ACTION: Final rule. ----------------------------------------------------------------------- SUMMARY: We are revising the Medicare hospital inpatient prospective payment systems (IPPS) for operating and capital-related costs of acute care hospitals to implement changes arising from our continuing experience with these systems for FY 2019. Some of these changes implement certain statutory provisions contained in the 21st Century Cures Act and the Bipartisan Budget Act of 2018, and other legislation. We also are making changes relating to Medicare graduate medical education (GME) affiliation agreements for new urban teaching hospitals. In addition, we are providing the market basket update that will apply to the rate-of-increase limits for certain hospitals excluded from the IPPS that are paid on a reasonable cost basis, subject to these limits for FY 2019. We are updating the payment policies and the annual payment rates for the Medicare prospective payment system (PPS) for inpatient hospital services provided by long- term care hospitals (LTCHs) for FY 2019. In addition, we are establishing new requirements or revising existing requirements for quality reporting by specific Medicare providers (acute care hospitals, PPS-exempt cancer hospitals, and LTCHs). We also are establishing new requirements or revising existing requirements for eligible professionals (EPs), eligible hospitals, and critical access hospitals (CAHs) participating in the Medicare and Medicaid Electronic Health Record (EHR) Incentive Programs (now referred to as the Promoting Interoperability Programs). In addition, we are finalizing modifications to the requirements that apply to States operating Medicaid Promoting Interoperability Programs. We are updating policies for the Hospital Value-Based Purchasing (VBP) Program, the Hospital Readmissions Reduction Program, and the Hospital- Acquired Condition (HAC) Reduction Program. We also are making changes relating to the required supporting documentation for an acceptable Medicare cost report submission and the supporting information for physician certification and recertification of claims. DATES: This final rule is effective on October 1, 2018.

Purpose and Legal Authority This final rule makes payment and policy changes under the Medicare inpatient prospective payment systems (IPPS) for operating and capital- related costs of acute care hospitals as well as for certain hospitals and hospital units excluded from the IPPS. In addition, it makes payment and policy changes for inpatient hospital services provided by long-term care hospitals (LTCHs) under the long-term care hospital prospective payment system (LTCH PPS). This final rule also makes policy changes to programs associated with Medicare IPPS hospitals, IPPS-excluded hospitals, and LTCHs. We are establishing new requirements and revising existing requirements for quality reporting by specific providers (acute care hospitals, PPS-exempt cancer hospitals, and LTCHs) that are participating in Medicare. We also are establishing new requirements and revising existing requirements for eligible professionals (EPs), eligible hospitals, and CAHs participating in the Medicare and Medicaid Promoting Interoperability Programs. We are updating policies for the Hospital Value-Based Purchasing (VBP) Program, the Hospital Readmissions Reduction Program, and the Hospital-Acquired Condition (HAC) Reduction Program. We are making changes relating to the supporting documentation required for an acceptable Medicare cost report submission and the supporting information for physician certification and recertification of claims. Under various statutory authorities, we are making changes to the Medicare IPPS, to the LTCH PPS, and to other related payment methodologies and programs for FY 2019 and subsequent fiscal years. These statutory authorities include, but are not limited to, the following:Section 1886(d) of the Social Security Act (the Act), which sets forth a system of payment for the operating costs of acute care hospital inpatient stays under Medicare Part A (Hospital Insurance) based on prospectively set rates. Section 1886(g) of the Act requires that, instead of paying for capital-related costs of inpatient hospital services on a reasonable cost basis, the Secretary use a prospective payment system (PPS). Section 1886(d)(1)(B) of the Act, which specifies that certain hospitals and hospital units are excluded from the IPPS. These hospitals and units are: Rehabilitation hospitals and units; LTCHs; psychiatric hospitals and units; children's hospitals; cancer hospitals; extended neoplastic disease care hospitals, and hospitals located outside the 50 States, the District of Columbia, and Puerto Rico (that is, hospitals located in the U.S. Virgin Islands, Guam, the Northern Mariana Islands, and American Samoa). Religious nonmedical health care institutions (RNHCIs) are also excluded from the IPPS. Sections 123(a) and (c) of the BBRA (Pub. L. 106-113) and section 307(b)(1) of the BIPA (Pub. L. 106-554) (as codified under section 1886(m)(1) of the Act), which provide for the development and implementation of a prospective payment system for payment for inpatient hospital services of LTCHs described in section 1886(d)(1)(B)(iv) of the Act. Sections 1814(l), 1820, and 1834(g) of the Act, which specify that payments are made to critical access hospitals (CAHs) (that is, rural hospitals or facilities that meet certain statutory requirements) for inpatient and outpatient services and that these payments are generally based on 101 percent of reasonable cost. Section 1866(k) of the Act, as added by section 3005 of the Affordable Care Act, which establishes a quality reporting program for hospitals described in section 1886(d)(1)(B)(v) of the Act, referred to as ``PPS-exempt cancer hospitals.'' Section 1886(a)(4) of the Act, which specifies that costs of approved educational activities are excluded from the operating costs of inpatient hospital services. Hospitals with approved graduate medical education (GME) programs are paid for the direct costs of GME in accordance with section 1886(h) of the Act. Section 1886(b)(3)(B)(viii) of the Act, which requires the Secretary to reduce the applicable percentage increase that would otherwise apply to the standardized amount applicable to a subsection (d) hospital for discharges occurring in a fiscal year if the hospital does not submit data on measures in a form and manner, and at a time, specified by the Secretary. Section 1886(o) of the Act, which requires the Secretary to establish a Hospital Value-Based Purchasing (VBP) Program, under which value-based incentive payments are made in a fiscal year to hospitals meeting performance standards established for a performance period for such fiscal year. Section 1886(p) of the Act, as added by section 3008 of the Affordable Care Act, which establishes a Hospital-Acquired Condition (HAC) Reduction Program, under which payments to applicable hospitals are adjusted to provide an incentive to reduce hospital- acquired conditions. Section 1886(q) of the Act, as added by section 3025 of the Affordable Care Act and amended by section 10309 of the Affordable Care Act and section 15002 of the 21st Century Cures Act, which establishes the ``Hospital [[Page 41147]] Readmissions Reduction Program.'' Under the program, payments for discharges from an ``applicable hospital'' under section 1886(d) of the Act will be reduced to account for certain excess readmissions. Section 15002 of the 21st Century Cures Act requires the Secretary to compare cohorts of hospitals to each other in determining the extent of excess readmissions. Section 1886(r) of the Act, as added by section 3133 of the Affordable Care Act, which provides for a reduction to disproportionate share hospital (DSH) payments under section 1886(d)(5)(F) of the Act and for a new uncompensated care payment to eligible hospitals. Specifically, section 1886(r) of the Act requires that, for fiscal year 2014 and each subsequent fiscal year, subsection (d) hospitals that would otherwise receive a DSH payment made under section 1886(d)(5)(F) of the Act will receive two separate payments: (1) 25 Percent of the amount they previously would have received under section 1886(d)(5)(F) of the Act for DSH (``the empirically justified amount''), and (2) an additional payment for the DSH hospital's proportion of uncompensated care, determined as the product of three factors. These three factors are: (1) 75 Percent of the payments that would otherwise be made under section 1886(d)(5)(F) of the Act; (2) 1 minus the percent change in the percent of individuals who are uninsured (minus 0.2 percentage point for FY 2018 and FY 2019); and (3) a hospital's uncompensated care amount relative to the uncompensated care amount of all DSH hospitals expressed as a percentage. Section 1886(m)(6) of the Act, as added by section 1206(a)(1) of the Pathway for Sustainable Growth Rate (SGR) Reform Act of 2013 (Pub. L. 113-67) and amended by section 51005(a) of the Bipartisan Budget Act of 2018 (Pub. L. 115-123), which provided for the establishment of site neutral payment rate criteria under the LTCH PPS, with implementation beginning in FY 2016, and provides for a 4-year transitional blended payment rate for discharges occurring in LTCH cost reporting periods beginning in FYs 2016 through 2019. Section 51005(b) of the Bipartisan Budget Act of 2018 amended section 1886(m)(6)(B) by adding new clause (iv), which specifies that the IPPS comparable amount defined in clause (ii)(I) shall be reduced by 4.6 percent for FYs 2018 through 2026. Section 1886(m)(6) of the Act, as amended by section 15009 of the 21st Century Cures Act (Pub. L. 114-255), which provides for a temporary exception to the application of the site neutral payment rate under the LTCH PPS for certain spinal cord specialty hospitals for discharges in cost reporting periods beginning during FYs 2018 and 2019. Section 1886(m)(6) of the Act, as amended by section 15010 of the 21st Century Cures Act (Pub. L. 114-255), which provides for a temporary exception to the application of the site neutral payment rate under the LTCH PPS for certain LTCHs with certain discharges with severe wounds occurring in cost reporting periods beginning during FY 2018. Section 1886(m)(5)(D)(iv) of the Act, as added by section 1206(c) of the Pathway for Sustainable Growth Rate (SGR) Reform Act of 2013 (Pub. L. 113-67), which provides for the establishment of a functional status quality measure in the LTCH QRP for change in mobility among inpatients requiring ventilator support. Section 1899B of the Act, as added by section 2(a) of the Improving Medicare Post-Acute Care Transformation Act of 2014 (IMPACT Act, Pub. L. 113-185), which provides for the establishment of standardized data reporting for certain post-acute care providers, including LTCHs. 2. Improving Patient Outcomes and Reducing Burden Through Meaningful Measures Regulatory reform and reducing regulatory burden are high priorities for CMS. To reduce the regulatory burden on the healthcare industry, lower health care costs, and enhance patient care, in October 2017, we launched the Meaningful Measures Initiative.\1\ This initiative is one component of our agency-wide Patients Over Paperwork Initiative,\2\ which is aimed at evaluating and streamlining regulations with a goal to reduce unnecessary cost and burden, increase efficiencies, and improve beneficiary experience. The Meaningful Measures Initiative is aimed at identifying the highest priority areas for quality measurement and quality improvement, in order to assess the core quality of care issues that are most vital to advancing our work to improve patient outcomes. The Meaningful Measures Initiative represents a new approach to quality measures that will foster operational efficiencies and will reduce costs, including collection and reporting burden while producing quality measurement that is more focused on meaningful outcomes. --------------------------------------------------------------------------- \1\ Meaningful Measures web page: https://www.cms.gov/Medicare/Quality-Initiatives-Patient-Assessment-Instruments/QualityInitiativesGenInfo/MMF/General-info-Sub-Page.html. \2\ Remarks by Administrator Seema Verma at the Health Care Payment Learning and Action Network (LAN) Fall Summit, as prepared for delivery on October 30, 2017. Available at: https://www.cms.gov/Newsroom/MediaReleaseDatabase/Fact-sheets/2017-Fact-Sheet-items/2017-10-30.html. --------------------------------------------------------------------------- The Meaningful Measures framework has the following objectives: Address high-impact measure areas that safeguard public health; Patient-centered and meaningful to patients; Outcome-based where possible; Fulfill each program's statutory requirements; Minimize the level of burden for health care providers (for example, through a preference for EHR-based measures, where possible, such as electronic clinical quality measures; \3\ --------------------------------------------------------------------------- \3\ We refer readers to section VIII.A.9.c. of the preamble of this final rule where we discuss public comments on the potential future development and adoption of eCQMs. --------------------------------------------------------------------------- Significant opportunity for improvement; Address measure needs for population based payment through alternative payment models; and Align across programs and/or with other payers. In order to achieve these objectives, we have identified 19 Meaningful Measures areas and mapped them to six overarching quality priorities, as shown in the following table: ------------------------------------------------------------------------ Quality priority Meaningful measure area ------------------------------------------------------------------------ Making Care Safer by Reducing Harm Healthcare-Associated Caused in the Delivery of Care. Infections. Preventable Healthcare Harm. Strengthen Person and Family Engagement Care is Personalized and as Partners in Their Care. Aligned with Patient's Goals. End of Life Care According to Preferences. Patient's Experience of Care. Patient Reported Functional Outcomes. [[Page 41148]] Promote Effective Communication and Medication Management. Coordination of Care. Admissions and Readmissions to Hospitals. Transfer of Health Information and Interoperability. Promote Effective Prevention and Preventive Care. Treatment of Chronic Disease. Management of Chronic Conditions. Prevention, Treatment, and Management of Mental Health. Prevention and Treatment of Opioid and Substance Use Disorders. Risk Adjusted Mortality. Work with Communities to Promote Best Equity of Care. Practices of Healthy Living. Community Engagement. Make Care Affordable................... Appropriate Use of Healthcare. Patient-focused Episode of Care. Risk Adjusted Total Cost of Care. ------------------------------------------------------------------------ By including Meaningful Measures in our programs, we believe that we can also address the following cross-cutting measure criteria: Eliminating disparities; Tracking measurable outcomes and impact; Safeguarding public health; Achieving cost savings; Improving access for rural communities; and Reducing burden. We believe that the Meaningful Measures Initiative will improve outcomes for patients, their families, and health care providers, while reducing burden and costs for clinicians and providers, as well as promoting operational efficiencies. We received numerous comments from stakeholders regarding the Meaningful Measures Initiative and the impact of its implementation in CMS' quality programs. Many of these comments pertained to specific program proposals, and are discussed in the appropriate program- specific sections of this final rule. However, commenters also provided insights and recommendations for the ongoing development of the Meaningful Measures Initiative generally, including: ensuring transparency in public reporting and usability of publicly reported data; evaluating the benefit of individual measures to patients via use in quality programs weighed against the burden to providers of collecting and reporting that measure data; and identifying additional opportunities for alignment across CMS quality programs. We look forward to continuing to work with stakeholders to refine and further implement the Meaningful Measures Initiative, and will take commenters' insights and recommendations into account moving forward. 3. Summary of the Major Provisions Below we provide a summary of the major provisions in this final rule. In general, these major provisions are as part of the annual update to the payment policies and payment rates, consistent with the applicable statutory provisions. A general summary of the proposed changes that we included in the proposed rule issued prior to this final rule is presented in section I.D. of the preamble of this final rule. a. MS-DRG Documentation and Coding Adjustment Section 631 of the American Taxpayer Relief Act of 2012 (ATRA, Pub. L. 112-240) amended section 7(b)(1)(B) of Public Law 110-90 to require the Secretary to make a recoupment adjustment to the standardized amount of Medicare payments to acute care hospitals to account for changes in MS-DRG documentation and coding that do not reflect real changes in case-mix, totaling $11 billion over a 4-year period of FYs 2014, 2015, 2016, and 2017. The FY 2014 through FY 2017 adjustments represented the amount of the increase in aggregate payments as a result of not completing the prospective adjustment authorized under section 7(b)(1)(A) of Public Law 110-90 until FY 2013. Prior to the ATRA, this amount could not have been recovered under Public Law 110- 90. Section 414 of the Medicare Access and CHIP Reauthorization Act of 2015 (MACRA) (Pub. L. 114-10) replaced the single positive adjustment we intended to make in FY 2018 with a 0.5 percent positive adjustment to the standardized amount of Medicare payments to acute care hospitals for FYs 2018 through 2023. (The FY 2018 adjustment was subsequently adjusted to 0.4588 percent by section 15005 of the 21st Century Cures Act.) Therefore, for FY 2019, we are making an adjustment of +0.5 percent to the standardized amount. b. Expansion of the Postacute Care Transfer Policy Section 53109 of the Bipartisan Budget Act of 2018 amended section 1886(d)(5)(J)(ii) of the Act to also include discharges to hospice care by a hospice program as a qualified discharge, effective for discharges occurring on or after October 1, 2018. Accordingly, we are making conforming amendments to Sec. 412.4(c) of the regulation, effective for discharges on or after October 1, 2018, to specify that if a discharge is assigned to one of the MS-DRGs subject to the postacute care transfer policy and the individual is transferred to hospice care by a hospice program, the discharge is subject to payment as a transfer case. c. DSH Payment Adjustment and Additional Payment for Uncompensated Care Section 3133 of the Affordable Care Act modified the Medicare disproportionate share hospital (DSH) payment methodology beginning in FY 2014. Under section 1886(r) of the Act, which was added by section 3133 of the Affordable Care Act, starting in FY 2014, DSHs receive 25 percent of the amount they previously would have received under the statutory formula for Medicare DSH payments in section 1886(d)(5)(F) of the Act. The remaining amount, equal to 75 percent of the amount that otherwise would have been paid as Medicare DSH payments, is paid as additional payments after the amount is reduced for changes in the percentage of individuals that are uninsured. Each Medicare DSH will receive an additional payment based on its share of the total amount of uncompensated care for all Medicare DSHs for a given time period. In this FY 2019 IPPS/LTCH PPS final rule, we are updating our estimates of the three factors used to determine uncompensated care payments for FY 2019. We are continuing to use uninsured estimates produced by CMS' Office of the Actuary (OACT) as part of the development of the National Health Expenditure Accounts (NHEA) in the calculation of Factor 2. We also are continuing to incorporate data from Worksheet S-10 in the calculation of hospitals' share of the aggregate amount [[Page 41149]] of uncompensated care by combining data on uncompensated care costs from Worksheet S-10 for FYs 2014 and 2015 with proxy data regarding a hospital's share of low-income insured days for FY 2013 to determine Factor 3 for FY 2019. In addition, we are using only data regarding low-income insured days for FY 2013 to determine the amount of uncompensated care payments for Puerto Rico hospitals, Indian Health Service and Tribal hospitals, and all-inclusive rate providers. For this final rule, we are establishing the following policies: (1) For providers with multiple cost reports, beginning in the same fiscal year, to use the longest cost report and annualize Medicaid data and uncompensated care data if a hospital's cost report does not equal 12 months of data; (2) in the rare case where a provider has multiple cost reports, beginning in the same fiscal year, but one report also spans the entirety of the following fiscal year, such that the hospital has no cost report for that fiscal year, the cost report that spans both fiscal years will be used for the latter fiscal year; and (3) to apply statistical trim methodologies to potentially aberrant cost-to-charge ratios (CCRs) and potentially aberrant uncompensated care costs reported on the Worksheet S-10. d. Changes to the LTCH PPS In this final rule, we set forth changes to the LTCH PPS Federal payment rates, factors, and other payment rate policies under the LTCH PPS for FY 2019. In addition, we are eliminating the 25-percent threshold policy, and under this policy, we are applying a one-time adjustment of approximately 0.9 percent to the LTCH PPS standard Federal payment rate in FY 2019 to ensure this elimination of the 25- percent threshold policy is budget neutral. e. Reduction of Hospital Payments for Excess Readmissions We are making changes to policies for the Hospital Readmissions Reduction Program, which was established under section 1886(q) of the Act, as added by section 3025 of the Affordable Care Act, as amended by section 10309 of the Affordable Care Act and further amended by section 15002 of the 21st Century Cures Act. The Hospital Readmissions Reduction Program requires a reduction to a hospital's base operating DRG payment to account for excess readmissions of selected applicable conditions. For FY 2018 and subsequent years, the reduction is based on a hospital's risk-adjusted readmission rate during a 3-year period for acute myocardial infarction (AMI), heart failure (HF), pneumonia, chronic obstructive pulmonary disease (COPD), total hip arthroplasty/ total knee arthroplasty (THA/TKA), and coronary artery bypass graft (CABG). In this final rule, we are establishing the applicable periods for FY 2019, FY 2020, and FY 2021. We also are codifying the definitions of dual-eligible patients, the proportion of dual- eligibles, and the applicable period for dual-eligibility. f. Hospital Value-Based Purchasing (VBP) Program Section 1886(o) of the Act requires the Secretary to establish a Hospital VBP Program under which value-based incentive payments are made in a fiscal year to hospitals based on their performance on measures established for a performance period for such fiscal year. As part of agency-wide efforts under the Meaningful Measures Initiative to use a parsimonious set of the most meaningful measures for patients, clinicians, and providers in our quality programs and the Patients Over Paperwork Initiative to reduce costs and burden and program complexity, as discussed in section I.A.2. of the preamble of this final rule, we are removing a total of 4 measures from the Hospital VBP Program, all of which will continue to be used in the Hospital IQR Program, in order to reduce the costs and complexity of tracking these measures in multiple programs. Specifically, we are removing one measure, beginning with the FY 2021 program year: (1) Elective Delivery (NQF #0469) (PC- 01). We also are removing three measures from the Hospital VBP Program, effective with the effective date of this FY 2019 IPPS/LTCH PPS final rule: (1) Hospital-Level, Risk-Standardized Payment Associated With a 30-Day Episode-of-Care for Acute Myocardial Infarction (NQF #2431) (AMI Payment); (2) Hospital-Level, Risk-Standardized Payment Associated With a 30-Day Episode-of-Care for Heart Failure (NQF #2436) (HF Payment); and (3) Hospital-Level, Risk-Standardized Payment Associated With a 30- Day Episode-of-Care for Pneumonia (PN Payment) (NQF #2579). In addition, we are renaming the Clinical Care domain as the Clinical Outcomes domain, beginning with the FY 2020 program year. We also are adopting measure removal factors for the Hospital VBP Program. We are not finalizing our proposals to remove of the following six patient safety measures: (1) National Healthcare Safety Network (NHSN) Catheter-Associated Urinary Tract Infection (CAUTI) Outcome Measure (NQF #0138); (2) National Healthcare Safety Network (NHSN) Central Line-Associated Bloodstream Infection (CLABSI) Outcome Measure (NQF #0139); (3) American College of Surgeons-Centers for Disease Control and Prevention (ACS-CDC) Harmonized Procedure Specific Surgical Site Infection (SSI) Outcome Measure (NQF #0753); (4) National Healthcare Safety Network (NHSN) Facility-wide Inpatient Hospital-onset Methicillin-resistant Staphylococcus aureus Bacteremia (MRSA) Outcome Measure (NQF #1716); (5) National Healthcare Safety Network (NHSN) Facility-wide Inpatient Hospital-onset Clostridium difficile Infection (CDI) Outcome Measure (NQF #1717); and (6) Patient Safety and Adverse Events (Composite) (NQF #0531) (PSI 90). We are not finalizing our proposal to remove the Safety domain from the Hospital VBP Program, as we are not finalizing our proposals to remove all of the measures in this domain, and therefore we also are not finalizing changes to the domain weighting. g. Hospital-Acquired Condition (HAC) Reduction Program Section 1886(p) of the Act, as added under section 3008(a) of the Affordable Care Act, establishes an incentive to hospitals to reduce the incidence of hospital-acquired conditions by requiring the Secretary to make an adjustment to payments to applicable hospitals effective for discharges beginning on October 1, 2014. This 1-percent payment reduction applies to a hospital whose ranking in the worst- performing quartile (25 percent) of all applicable hospitals, relative to the national average, of conditions acquired during the applicable period and on all of the hospital's discharges for the specified fiscal year. As part of our agency-wide Patients over Paperwork and Meaningful Measures Initiatives, discussed in section I.A.2. of the preamble of this final rule, we are retaining the measures currently included in the HAC Reduction Program because the measures address a performance gap in patient safety and reduce harm caused in the delivery of care. In this final rule, we are: (1) Establishing administrative policies to collect, validate, and publicly report NHSN healthcare-associated infection (HAI) quality measure data that facilitate a seamless transition, independent of the Hospital IQR Program, beginning with January 1, 2020 infectious events; (2) changing the scoring methodology by removing domains and assigning equal weighting to each measure for which a hospital has a measure; and (3) establishing the [[Page 41150]] applicable period for FY 2021. In addition, we are summarizing comments we received regarding the potential future inclusion of additional measures, including eCQMs. h. Hospital Inpatient Quality Reporting (IQR) Program Under section 1886(b)(3)(B)(viii) of the Act, subsection (d) hospitals are required to report data on measures selected by the Secretary for a fiscal year in order to receive the full annual percentage increase that would otherwise apply to the standardized amount applicable to discharges occurring in that fiscal year. In this final rule, we are making several changes. As part of agency-wide efforts under the Meaningful Measures Initiative to use a parsimonious set of the most meaningful measures for patients and clinicians in our quality programs and the Patients Over Paperwork initiative to reduce burden, cost, and program complexity, as discussed in section I.A.2. of the preamble of this final rule, we are adding a new measure removal factor and removing a total of 39 measures from the Hospital IQR Program. We are finalizing a modified version of our proposal to remove 5 of those measures such that removal is delayed by 1 year. For a full list of measures being removed, we refer readers to section VIII.A.5.c. of the preamble of this final rule. Beginning with the CY 2018 reporting period/FY 2020 payment determination and subsequent years, we are removing 17 claims-based measures and two structural measures. Beginning with the CY 2019 reporting period/FY 2021 payment determination and subsequent years, we are removing three chart-abstracted measures and two claims-based measures. Beginning with the CY 2020 reporting period/FY 2022 payment determination and subsequent years, we are removing six chart-abstracted measures, one claims-based measure, and seven eCQMs from the Hospital IQR Program measure set. Beginning with the CY 2021 reporting period/FY 2023 payment determination, we are removing one claims-based measure. In addition, for the CY 2019 reporting period/FY 2021 payment determination, we are: (1) Requiring the same eCQM reporting requirements that were adopted for the CY 2018 reporting period/FY 2020 payment determination (82 FR 38355 through 38361), such that hospitals submit one, self-selected calendar quarter of 2019 data for 4 eCQMs in the Hospital IQR Program measure set; and (2) requiring that hospitals use the 2015 Edition certification criteria for CEHRT. These changes are in alignment with changes or current established policies under the Medicare and Medicaid Promoting Interoperability Programs (previously known as the Medicare and Medicaid EHR Incentive Programs). In addition, we are summarizing public comments we received on two measures we are considering for potential future inclusion in the Hospital IQR Program, as well as on the potential future development and adoption of electronic clinical quality measures generally. i. Long-Term Care Hospital Quality Reporting Program (LTCH QRP) The LTCH QRP is authorized by section 1886(m)(5) of the Act and applies to all hospitals certified by Medicare as long-term care hospitals (LTCHs). Under the LTCH QRP, the Secretary reduces by 2 percentage points the annual update to the LTCH PPS standard Federal rate for discharges for an LTCH during a fiscal year if the LTCH fails to submit data in accordance with the LTCH QRP requirements specified for that fiscal year. As part of agency-wide efforts under the Meaningful Measures Initiative to use a parsimonious set of the most meaningful measures for patients and clinicians in our quality programs and the Patients Over Paperwork Initiative to reduce cost and burden and program complexity, as discussed in section I.A.2. of the preamble of this final rule, we are removing three measures from the LTCH QRP. We also are adopting a new measure removal factor and are codifying the measure removal factors in our regulations. In addition, we are updating our regulations to expand the methods by which an LTCH is notified of noncompliance with the requirements of the LTCH QRP for a program year and how CMS will notify an LTCH of a reconsideration decision. j. Medicare and Medicaid Promoting Interoperability Programs (Previously Referred to as Medicare and Medicaid EHR Incentive Programs) In this final rule, we are finalizing several changes to reduce burden, increase interoperability and improve patient electronic access to their health information under the Medicare and Medicaid Promoting Interoperability Programs (previously referred to as Medicare and Medicaid EHR Incentive Programs). Specifically, we are finalizing: (1) An EHR reporting period of a minimum of any continuous 90 days in CYs 2019 and 2020 for new and returning participants attesting to CMS or their State Medicaid agency; (2) modifications to our proposed performance-based scoring methodology, which consists of a smaller set of objectives as well as a smaller set of new and modified measures; (3) the removal of certain CQMs beginning with the reporting period in CY 2020 as well as the CY 2019 reporting requirements we proposed to align the CQM reporting requirements for the Promoting Interoperability Programs with the Hospital IQR Program; (4) the codification of policies for subsection (d) Puerto Rico hospitals; (5) amendments to the prior approval policy applicable in the Medicaid Promoting Interoperability Program to align with the prior approval policy for MMIS and ADP systems and to minimize burden on States; and (6) deadlines for funding availability for States to conclude the Medicaid Promoting Interoperability Program. 4. Summary of Costs and Benefits Adjustment for MS-DRG Documentation and Coding Changes. Section 414 of the MACRA replaced the single positive adjustment we intended to make in FY 2018 once the recoupment required by section 631 of the ATRA was complete with a 0.5 percent positive adjustment to the standardized amount of Medicare payments to acute care hospitals for FYs 2018 through 2023. (The FY 2018 adjustment was subsequently adjusted to 0.4588 percent by section 15005 of the 21st Century Cures Act.) For FY 2019, we are making an adjustment of +0.5 percent to the standardized amount consistent with the MACRA. Expansion of the Postacute Care Transfer Policy. Section 53109 of the Bipartisan Budget Act of 2018 amended section 1886(d)(5)(J)(ii) of the Act to also include discharges to hospice care by a hospice program as a qualified discharge, effective for discharges occurring on or after October 1, 2018. Accordingly, we are making conforming amendments to Sec. 412.4(c) of the regulation to specify that, effective for discharges on or after October 1, 2018, if a discharge is assigned to one of the MS-DRGs subject to the postacute care transfer policy, and the individual is transferred to hospice care by a hospice program, the discharge will be subject to payment as a transfer case. We estimate that this statutory expansion to the postacute care transfer policy will reduce Medicare payments under the IPPS by approximately $240 million in FY 2019. Medicare DSH Payment Adjustment and Additional Payment for Uncompensated Care. Under section 1886(r) of the Act (as added by section [[Page 41151]] 3133 of the Affordable Care Act), DSH payments to hospitals under section 1886(d)(5)(F) of the Act are reduced and an additional payment for uncompensated care is made to eligible hospitals, beginning in FY 2014. Hospitals that receive Medicare DSH payments receive 25 percent of the amount they previously would have received under the statutory formula for Medicare DSH payments in section 1886(d)(5)(F) of the Act. The remainder, equal to an estimate of 75 percent of what otherwise would have been paid as Medicare DSH payments, is the basis for determining the additional payments for uncompensated care after the amount is reduced for changes in the percentage of individuals that are uninsured and additional statutory adjustments. Each hospital that receives Medicare DSH payments will receive an additional payment for uncompensated care based on its share of the total uncompensated care amount reported by Medicare DSHs. The reduction to Medicare DSH payments is not budget neutral. For FY 2019, we are updating our estimates of the three factors used to determine uncompensated care payments. We are continuing to use uninsured estimates produced by OACT as part of the development of the NHEA in the calculation of Factor 2. We also are continuing to incorporate data from Worksheet S-10 in the calculation of hospitals' share of the aggregate amount of uncompensated care by combining data on uncompensated care costs from Worksheet S-10 for FY 2014 and FY 2015 with proxy data regarding a hospital's share of low-income insured days for FY 2013 to determine Factor 3 for FY 2019. To determine the amount of uncompensated care for Puerto Rico hospitals, Indian Health Service and Tribal hospitals, and all-inclusive rate providers, we are using only the data regarding low-income insured days for FY 2013. In addition, in this final rule, we are establishing the following policies: (1) For providers with multiple cost reports beginning in the same fiscal year, to use the longest cost report and annualize Medicaid data and uncompensated care data if a hospital's cost report does not equal 12 months of data; (2) in the rare case where a provider has multiple cost reports beginning in the same fiscal year, but one report also spans the entirety of the following fiscal year such that the hospital has no cost report for that fiscal year, the cost report that spans both fiscal years will be used for the latter fiscal year; and (3) to apply statistical trim methodologies to potentially aberrant CCRs and potentially aberrant uncompensated care costs. We project that the amount available to distribute as payments for uncompensated care for FY 2019 will increase by approximately $1.5 billion, as compared to the estimate of overall payments, including Medicare DSH payments and uncompensated care payments, that will be distributed in FY 2018. The payments have redistributive effects, based on a hospital's uncompensated care amount relative to the uncompensated care amount for all hospitals that are estimated to receive Medicare DSH payments, and the calculated payment amount is not directly tied to a hospital's number of discharges. Update to the LTCH PPS Payment Rates and Other Payment Policies. Based on the best available data for the 409 LTCHs in our database, we estimate that the changes to the payment rates and factors that we present in the preamble and Addendum of this final rule, which reflect the continuation of the transition of the statutory application of the site neutral payment rate, the update to the LTCH PPS standard Federal payment rate for FY 2019, and the one-time permanent adjustment of approximately 0.9 percent to the LTCH PPS standard Federal payment rate to ensure the elimination of the 25-percent threshold policy is budget neutral, will result in an estimated increase in payments in FY 2019 of approximately $39 million. Changes to the Hospital Readmissions Reduction Program. For FY 2019 and subsequent years, the reduction is based on a hospital's risk-adjusted readmission rate during a 3-year period for acute myocardial infarction (AMI), heart failure (HF), pneumonia, chronic obstructive pulmonary disease (COPD), total hip arthroplasty/ total knee arthroplasty (THA/TKA), and coronary artery bypass graft (CABG). Overall, in this final rule, we estimate that 2,610 hospitals will have their base operating DRG payments reduced by their determined proxy FY 2019 hospital-specific readmission adjustment. As a result, we estimate that the Hospital Readmissions Reduction Program will save approximately $566 million in FY 2019. Value-Based Incentive Payments under the Hospital VBP Program. We estimate that there will be no net financial impact to the Hospital VBP Program for the FY 2019 program year in the aggregate because, by law, the amount available for value-based incentive payments under the program in a given year must be equal to the total amount of base operating MS-DRG payment amount reductions for that year, as estimated by the Secretary. The estimated amount of base operating MS-DRG payment amount reductions for the FY 2019 program year and, therefore, the estimated amount available for value-based incentive payments for FY 2019 discharges is approximately $1.9 billion. Changes to the HAC Reduction Program. A hospital's Total HAC score and its ranking in comparison to other hospitals in any given year depend on several different factors. Any significant impact due to the HAC Reduction Program changes for FY 2019, including which hospitals will receive the adjustment, will depend on actual experience. The removal of NHSN HAI measures from the Hospital IQR Program and the subsequent cessation of its validation processes for NHSN HAI measures and the creation of a validation process for the HAC Reduction program represent no net change in reporting burden across CMS hospital quality programs. However, with the finalization of our proposal to remove HAI chart-abstracted measures from the Hospital IQR Program, we anticipate a total burden shift of 43,200 hours and approximately $1.6 million, as a result of no longer needing to validate those HAI measures under the Hospital IQR Program and beginning the validation process under the HAC Reduction Program. Changes to the Hospital Inpatient Quality Reporting (IQR) Program. Across 3,300 IPPS hospitals, we estimate that our finalized requirements for the Hospital IQR Program in this final rule will result in the following changes to costs and burdens related to information collection for this program, compared to previously adopted requirements: (1) A total collection of information burden reduction of 1,046,138 hours and a total cost reduction of approximately $38.3 million for the CY 2019 reporting period/FY 2021 payment determination, due to the removal of ED-1, IMM-2, and VTE-6 measures; and (2) a total collection of information burden reduction of 858,000 hours and a total cost reduction of $31.3 million for the CY 2020 reporting period/FY 2022 payment determination due to the removal of ED-2; and (3) a total collection of information burden reduction of 43,200 hours and a total of $1.6 million for the CY 2021 reporting period/FY 2023 payment determination due to validation of the NHSN HAI measures no longer being conducted under the Hospital IQR Program once the HAC Reduction Program begins validating these measures, as discussed [[Page 41152]] in the preamble of this final rule for the HAC Reduction Program. Further, we anticipate that the removal of 39 measures will result in a reduction in costs unrelated to information collection. For example, it may be costly for health care providers to track the confidential feedback, preview reports, and publicly reported information on a measure where we use the measure in more than one program. Also, when measures are in multiple programs, maintaining the specifications for those measures, as well as the tools we need to collect, validate, analyze, and publicly report the measure data may result in costs to CMS. In addition, beneficiaries may find it confusing to see public reporting on the same measure in different programs. We anticipate that our finalized policies will reduce the above-described costs. Changes Related to the LTCH QRP. In this final rule, we are removing two measures beginning with the FY 2020 LTCH QRP and one measure beginning with the FY 2021 LTCH QRP, for a total of three measures. We also are adopting a new quality measure removal factor for the LTCH QRP. We estimate that the impact of these changes is a reduction in costs of approximately $1,148 per LTCH annually or approximately $482,469 for all LTCHs annually. Changes to the Medicare and Medicaid Promoting Interoperability Programs. We believe that, overall, the finalized proposals in this final rule will reduce burden, as described in detail in section XIV.B.9. of the preamble and Appendix A, section I.N. of this final rule. B. Background Summary 1. Acute Care Hospital Inpatient Prospective Payment System (IPPS) Section 1886(d) of the Social Security Act (the Act) sets forth a system of payment for the operating costs of acute care hospital inpatient stays under Medicare Part A (Hospital Insurance) based on prospectively set rates. Section 1886(g) of the Act requires the Secretary to use a prospective payment system (PPS) to pay for the capital-related costs of inpatient hospital services for these ``subsection (d) hospitals.'' Under these PPSs, Medicare payment for hospital inpatient operating and capital-related costs is made at predetermined, specific rates for each hospital discharge. Discharges are classified according to a list of diagnosis-related groups (DRGs). The base payment rate is comprised of a standardized amount that is divided into a labor-related share and a nonlabor-related share. The labor-related share is adjusted by the wage index applicable to the area where the hospital is located. If the hospital is located in Alaska or Hawaii, the nonlabor-related share is adjusted by a cost-of- living adjustment factor. This base payment rate is multiplied by the DRG relative weight. If the hospital treats a high percentage of certain low-income patients, it receives a percentage add-on payment applied to the DRG- adjusted base payment rate. This add-on payment, known as the disproportionate share hospital (DSH) adjustment, provides for a percentage increase in Medicare payments to hospitals that qualify under either of two statutory formulas designed to identify hospitals that serve a disproportionate share of low-income patients. For qualifying hospitals, the amount of this adjustment varies based on the outcome of the statutory calculations. The Affordable Care Act revised the Medicare DSH payment methodology and provides for a new additional Medicare payment that considers the amount of uncompensated care beginning on October 1, 2013. If the hospital is training residents in an approved residency program(s), it receives a percentage add-on payment for each case paid under the IPPS, known as the indirect medical education (IME) adjustment. This percentage varies, depending on the ratio of residents to beds. Additional payments may be made for cases that involve new technologies or medical services that have been approved for special add-on payments. To qualify, a new technology or medical service must demonstrate that it is a substantial clinical improvement over technologies or services otherwise available, and that, absent an add- on payment, it would be inadequately paid under the regular DRG payment. The costs incurred by the hospital for a case are evaluated to determine whether the hospital is eligible for an additional payment as an outlier case. This additional payment is designed to protect the hospital from large financial losses due to unusually expensive cases. Any eligible outlier payment is added to the DRG-adjusted base payment rate, plus any DSH, IME, and new technology or medical service add-on adjustments. Although payments to most hospitals under the IPPS are made on the basis of the standardized amounts, some categories of hospitals are paid in whole or in part based on their hospital-specific rate, which is determined from their costs in a base year. For example, sole community hospitals (SCHs) receive the higher of a hospital-specific rate based on their costs in a base year (the highest of FY 1982, FY 1987, FY 1996, or FY 2006) or the IPPS Federal rate based on the standardized amount. SCHs are the sole source of care in their areas. Specifically, section 1886(d)(5)(D)(iii) of the Act defines an SCH as a hospital that is located more than 35 road miles from another hospital or that, by reason of factors such as an isolated location, weather conditions, travel conditions, or absence of other like hospitals (as determined by the Secretary), is the sole source of hospital inpatient services reasonably available to Medicare beneficiaries. In addition, certain rural hospitals previously designated by the Secretary as essential access community hospitals are considered SCHs. Under current law, the Medicare-dependent, small rural hospital (MDH) program is effective through FY 2022. Through and including FY 2006, an MDH received the higher of the Federal rate or the Federal rate plus 50 percent of the amount by which the Federal rate was exceeded by the higher of its FY 1982 or FY 1987 hospital-specific rate. For discharges occurring on or after October 1, 2007, but before October 1, 2022, an MDH receives the higher of the Federal rate or the Federal rate plus 75 percent of the amount by which the Federal rate is exceeded by the highest of its FY 1982, FY 1987, or FY 2002 hospital- specific rate. MDHs are a major source of care for Medicare beneficiaries in their areas. Section 1886(d)(5)(G)(iv) of the Act defines an MDH as a hospital that is located in a rural area (or, as amended by the Bipartisan Budget Act of 2018, a hospital located in a State with no rural area that meets certain statutory criteria), has not more than 100 beds, is not an SCH, and has a high percentage of Medicare discharges (not less than 60 percent of its inpatient days or discharges in its cost reporting year beginning in FY 1987 or in two of its three most recently settled Medicare cost reporting years). Section 1886(g) of the Act requires the Secretary to pay for the capital-related costs of inpatient hospital services in accordance with a prospective payment system established by the Secretary. The basic methodology for determining capital prospective payments is set forth in our regulations at 42 CFR 412.308 and 412.312. Under the capital IPPS, payments are adjusted by the same DRG for the case as they are under the operating IPPS. Capital IPPS payments are also adjusted for IME and DSH, similar to the adjustments made under the operating IPPS. In addition, hospitals may receive outlier payments for those cases that have unusually high costs. [[Page 41153]] The existing regulations governing payments to hospitals under the IPPS are located in 42 CFR part 412, subparts A through M. 2. Hospitals and Hospital Units Excluded From the IPPS Under section 1886(d)(1)(B) of the Act, as amended, certain hospitals and hospital units are excluded from the IPPS. These hospitals and units are: Inpatient rehabilitation facility (IRF) hospitals and units; long-term care hospitals (LTCHs); psychiatric hospitals and units; children's hospitals; cancer hospitals; extended neoplastic disease care hospitals, and hospitals located outside the 50 States, the District of Columbia, and Puerto Rico (that is, hospitals located in the U.S. Virgin Islands, Guam, the Northern Mariana Islands, and American Samoa). Religious nonmedical health care institutions (RNHCIs) are also excluded from the IPPS. Various sections of the Balanced Budget Act of 1997 (BBA, Pub. L. 105-33), the Medicare, Medicaid and SCHIP [State Children's Health Insurance Program] Balanced Budget Refinement Act of 1999 (BBRA, Pub. L. 106-113), and the Medicare, Medicaid, and SCHIP Benefits Improvement and Protection Act of 2000 (BIPA, Pub. L. 106-554) provide for the implementation of PPSs for IRF hospitals and units, LTCHs, and psychiatric hospitals and units (referred to as inpatient psychiatric facilities (IPFs)). (We note that the annual updates to the LTCH PPS are included along with the IPPS annual update in this document. Updates to the IRF PPS and IPF PPS are issued as separate documents.) Children's hospitals, cancer hospitals, hospitals located outside the 50 States, the District of Columbia, and Puerto Rico (that is, hospitals located in the U.S. Virgin Islands, Guam, the Northern Mariana Islands, and American Samoa), and RNHCIs continue to be paid solely under a reasonable cost-based system, subject to a rate-of-increase ceiling on inpatient operating costs. Similarly, extended neoplastic disease care hospitals are paid on a reasonable cost basis, subject to a rate-of-increase ceiling on inpatient operating costs. The existing regulations governing payments to excluded hospitals and hospital units are located in 42 CFR parts 412 and 413. 3. Long-Term Care Hospital Prospective Payment System (LTCH PPS) The Medicare prospective payment system (PPS) for LTCHs applies to hospitals described in section 1886(d)(1)(B)(iv) of the Act, effective for cost reporting periods beginning on or after October 1, 2002. The LTCH PPS was established under the authority of sections 123 of the BBRA and section 307(b) of the BIPA (as codified under section 1886(m)(1) of the Act). During the 5-year (optional) transition period, a LTCH's payment under the PPS was based on an increasing proportion of the LTCH Federal rate with a corresponding decreasing proportion based on reasonable cost principles. Effective for cost reporting periods beginning on or after October 1, 2006 through September 30, 2015 all LTCHs were paid 100 percent of the Federal rate. Section 1206(a) of the Pathway for SGR Reform Act of 2013 (Pub. L. 113-67) established the site neutral payment rate under the LTCH PPS, which made the LTCH PPS a dual rate payment system beginning in FY 2016. Under this statute, based on a rolling effective date that is linked to the date on which a given LTCH's Federal FY 2016 cost reporting period begins, LTCHs are generally paid for discharges at the site neutral payment rate unless the discharge meets the patient criteria for payment at the LTCH PPS standard Federal payment rate. The existing regulations governing payment under the LTCH PPS are located in 42 CFR part 412, subpart O. Beginning October 1, 2009, we issue the annual updates to the LTCH PPS in the same documents that update the IPPS (73 FR 26797 through 26798). 4. Critical Access Hospitals (CAHs) Under sections 1814(l), 1820, and 1834(g) of the Act, payments made to critical access hospitals (CAHs) (that is, rural hospitals or facilities that meet certain statutory requirements) for inpatient and outpatient services are generally based on 101 percent of reasonable cost. Reasonable cost is determined under the provisions of section 1861(v) of the Act and existing regulations under 42 CFR part 413. 5. Payments for Graduate Medical Education (GME) Under section 1886(a)(4) of the Act, costs of approved educational activities are excluded from the operating costs of inpatient hospital services. Hospitals with approved graduate medical education (GME) programs are paid for the direct costs of GME in accordance with section 1886(h) of the Act. The amount of payment for direct GME costs for a cost reporting period is based on the hospital's number of residents in that period and the hospital's costs per resident in a base year. The existing regulations governing payments to the various types of hospitals are located in 42 CFR part 413. C. Summary of Provisions of Recent Legislation Implemented in This Final Rule 1. Pathway for SGR Reform Act of 2013 (Pub. L. 113-67) The Pathway for SGR Reform Act of 2013 (Pub. L. 113-67) introduced new payment rules in the LTCH PPS. Under section 1206 of this law, discharges in cost reporting periods beginning on or after October 1, 2015, under the LTCH PPS, receive payment under a site neutral rate unless the discharge meets certain patient-specific criteria. In this final rule, we are continuing to update certain policies that implemented provisions under section 1206 of the Pathway for SGR Reform Act. 2. Improving Medicare Post-Acute Care Transformation Act of 2014 (IMPACT Act) (Pub. L. 113-185) The Improving Medicare Post-Acute Care Transformation Act of 2014 (IMPACT Act) (Pub. L. 113-185), enacted on October 6, 2014, made a number of changes that affect the Long-Term Care Hospital Quality Reporting Program (LTCH QRP). In this final rule, we are continuing to implement portions of section 1899B of the Act, as added by section 2(a) of the IMPACT Act, which, in part, requires LTCHs, among other post-acute care providers, to report standardized patient assessment data, data on quality measures, and data on resource use and other measures. 3. The Medicare Access and CHIP Reauthorization Act of 2015 (Pub. L. 114-10) Section 414 of the Medicare Access and CHIP Reauthorization Act of 2015 (MACRA, Pub. L. 114-10) specifies a 0.5 percent positive adjustment to the standardized amount of Medicare payments to acute care hospitals for FYs 2018 through 2023. These adjustments follow the recoupment adjustment to the standardized amounts under section 1886(d) of the Act based upon the Secretary's estimates for discharges occurring from FYs 2014 through 2017 to fully offset $11 billion, in accordance with section 631 of the ATRA. The FY 2018 adjustment was subsequently adjusted to 0.4588 percent by section 15005 of the 21st Century Cures Act. 4. The 21st Century Cures Act (Pub. L. 114-255) The 21st Century Cures Act (Pub. L. 114-255), enacted on December 13, 2016, contained the following provision affecting payments under the Hospital Readmissions Reduction Program, [[Page 41154]] which we are continuing to implement in this final rule: Section 15002, which amended section 1886(q)(3) of the Act by adding subparagraphs (D) and (E), which requires the Secretary to develop a methodology for calculating the excess readmissions adjustment factor for the Hospital Readmissions Reduction Program based on cohorts defined by the percentage of dual-eligible patients (that is, patients who are eligible for both Medicare and full-benefit Medicaid coverage) cared for by a hospital. In this final rule, we are continuing to implement changes to the payment adjustment factor to assess penalties based on a hospital's performance, relative to other hospitals treating a similar proportion of dual-eligible patients. 5. The Bipartisan Budget Act of 2018 (Pub. L. 115-123) The Bipartisan Budget Act of 2018 (Pub. L. 115-123), enacted on February 9, 2018, contains provisions affecting payments under the IPPS and the LTCH PPS, which we are implementing or continuing to implement in this final rule: Section 50204 amended section 1886(d)(12) of the Act to provide for certain temporary changes to the low-volume hospital payment adjustment policy for FYs 2018 through 2022. For FY 2018, this provision extends the qualifying criteria and payment adjustment formula that applied for FYs 2011 through 2017. For FYs 2019 through 2022, this provision modifies the discharge criterion and payment adjustment formula. In FY 2023 and subsequent fiscal years, the qualifying criteria and payment adjustment revert to the requirements that were in effect for FYs 2005 through 2010. Section 50205 extends the MDH program through FY 2022. It also provides for an eligible hospital that is located in a State with no rural area to qualify for MDH status under an expanded definition if the hospital satisfies any of the statutory criteria at section 1886(d)(8)(E)(ii)(I), (II) (as of January 1, 2018), or (III) of the Act to be reclassified as rural. Section 51005(a) modified section 1886(m)(6) of the Act by extending the blended payment rate for site neutral payment rate LTCH discharges for cost reporting periods beginning in FY 2016 by an additional 2 years (FYs 2018 and 2019). In addition, section 51005(b) reduces the LTCH IPPS comparable per diem amount used in the site neutral payment rate for FYs 2018 through 2026 by 4.6 percent. In this final rule, we are making conforming changes to the existing regulations. Section 53109 modified section 1886(d)(5)(J) of the Act to require that, beginning in FY 2019, discharges to hospice care also qualify as a postacute care transfer and are subject to payment adjustments. D. Issuance of a Notice of Proposed Rulemaking In the proposed rule that appeared in the Federal Register on May 7, 2018 (83 FR 20164), we set forth proposed payment and policy changes to the Medicare IPPS for FY 2019 operating costs and for capital- related costs of acute care hospitals and certain hospitals and hospital units that are excluded from IPPS. In addition, we set forth proposed changes to the payment rates, factors, and other payment and policy-related changes to programs associated with payment rate policies under the LTCH PPS for FY 2019. Below is a general summary of the major changes that we proposed to make in the proposed rule. 1.

Proposed Changes to the Payment Rates for Certain Excluded Hospitals: Rate-of-Increase Percentages In section VI. of the preamble of the proposed rule, we discussed-- Proposed changes to payments to certain excluded hospitals for FY 2019. Proposed changes to the regulations governing satellite facilities. Proposed changes to the regulations governing excluded units of hospitals. Proposed continued implementation of the Frontier Community Health Integration Project (FCHIP) Demonstration. 6. Proposed Changes to the LTCH PPS In section VII. of the preamble of the proposed rule, we set forth-- Proposed changes to the LTCH PPS Federal payment rates, factors, and other payment rate policies under the LTCH PPS for FY 2019. Proposed changes to the blended payment rate for site neutral payment rate cases. Proposed elimination of the 25-percent threshold policy. 7. Proposed Changes Relating to Quality Data Reporting for Specific Providers and Suppliers In section VIII. of the preamble of the proposed rule, we address-- Proposed requirements for the Hospital Inpatient Quality Reporting (IQR) Program. Proposed changes to the requirements for the quality reporting program for PPS-exempt cancer hospitals (PCHQR Program). Proposed changes to the requirements under the LTCH Quality Reporting Program (LTCH QRP). Proposed changes to requirements pertaining to the clinical quality measurement for eligible hospitals and CAHs participating in the Medicare and Medicaid Promoting Interoperability Programs. 8. Proposed Revision to the Supporting Documentation Requirements for an Acceptable Medicare Cost Report Submission In section IX. of the preamble of the proposed rule, we set forth proposed revisions to the supporting documentation required for an acceptable Medicare cost report submission. 9. Requirements for Hospitals To Make Public List of Standard Charges In section X. of the preamble of the proposed rule, we discussed our efforts to further improve the public accessibility of hospital standard charge information, effective January 1, 2019, in accordance with section 2718(e) of the Public Health Service Act. 10. Proposed Revisions Regarding Physician Certification and Recertification of Claims In section XI. of the preamble of the proposed rule, we set forth proposed revisions to the requirements for supporting information used for physician certification and recertification of claims. 11. Request for Information In section XII. of the preamble of the proposed rule, we included a request for information on the possible establishment of CMS patient health and safety requirements for hospitals and other Medicare- and Medicaid-participating providers and suppliers for interoperable electronic health records and systems for electronic health care information exchange. 12. Determining Prospective Payment Operating and Capital Rates and Rate-of-Increase Limits for Acute Care Hospitals In sections II. and III. of the Addendum to the proposed rule, we set forth the proposed changes to the amounts and factors for determining the proposed FY 2019 prospective payment rates for operating costs and capital-related costs for acute care hospitals. We proposed to establish the threshold amounts for outlier cases. In addition, in section IV. of the Addendum to the proposed rule, we addressed the update factors for determining the rate-of-increase limits for cost reporting periods beginning in FY 2019 for certain hospitals excluded from the IPPS. 13. Determining Prospective Payment Rates for LTCHs In section V. of the Addendum to the proposed rule, we set forth proposed changes to the amounts and factors for determining the proposed FY 2019 LTCH PPS standard Federal payment rate and other factors used to determine LTCH PPS payments under both the LTCH PPS standard Federal payment rate and the site neutral payment rate in FY 2019. We proposed to establish the adjustments for wage levels, the labor-related share, the cost-of-living adjustment, and high-cost outliers, including the applicable fixed-loss amounts and the LTCH cost-to-charge ratios (CCRs) for both payment rates. 14. Impact Analysis In Appendix A of the proposed rule, we set forth an analysis of the impact the proposed changes would have on affected acute care hospitals, CAHs, LTCHs, and PCHs. 15. Recommendation of Update Factors for Operating Cost Rates of Payment for Hospital Inpatient Services In Appendix B of the proposed rule, as required by sections 1886(e)(4) and (e)(5) of the Act, we provided our recommendations of the appropriate percentage changes for FY 2019 for the following: A single average standardized amount for all areas for hospital inpatient services paid under the IPPS for operating costs of acute care hospitals (and hospital-specific rates applicable to SCHs and MDHs). Target rate-of-increase limits to the allowable operating costs of hospital inpatient services furnished by certain hospitals excluded from the IPPS. The LTCH PPS standard Federal payment rate and the site neutral payment rate for hospital inpatient services provided for LTCH PPS discharges. 16. Discussion of Medicare Payment Advisory Commission Recommendations Under section 1805(b) of the Act, MedPAC is required to submit a report to Congress, no later than March 15 of each year, in which MedPAC reviews and makes recommendations on Medicare payment policies. MedPAC's March 2018 recommendations concerning hospital inpatient payment [[Page 41156]] policies addressed the update factor for hospital inpatient operating costs and capital-related costs for hospitals under the IPPS. We addressed these recommendations in Appendix B of the proposed rule. For further information relating specifically to the MedPAC March 2018 report or to obtain a copy of the report, contact MedPAC at (202) 220- 3700 or visit MedPAC's website at: http://www.medpac.gov. II. Changes to Medicare Severity Diagnosis-Related Group (MS-DRG) Classifications and Relative Weights A. Background Section 1886(d) of the Act specifies that the Secretary shall establish a classification system (referred to as diagnosis-related groups (DRGs)) for inpatient discharges and adjust payments under the IPPS based on appropriate weighting factors assigned to each DRG. Therefore, under the IPPS, Medicare pays for inpatient hospital services on a rate per discharge basis that varies according to the DRG to which a beneficiary's stay is assigned. The formula used to calculate payment for a specific case multiplies an individual hospital's payment rate per case by the weight of the DRG to which the case is assigned. Each DRG weight represents the average resources required to care for cases in that particular DRG, relative to the average resources used to treat cases in all DRGs. Section 1886(d)(4)(C) of the Act requires that the Secretary adjust the DRG classifications and relative weights at least annually to account for changes in resource consumption. These adjustments are made to reflect changes in treatment patterns, technology, and any other factors that may change the relative use of hospital resources. B. MS-DRG Reclassifications For general information about the MS-DRG system, including yearly reviews and changes to the MS-DRGs, we refer readers to the previous discussions in the FY 2010 IPPS/RY 2010 LTCH PPS final rule (74 FR 43764 through 43766) and the FYs 2011 through 2018 IPPS/LTCH PPS final rules (75 FR 50053 through 50055; 76 FR 51485 through 51487; 77 FR 53273; 78 FR 50512; 79 FR 49871; 80 FR 49342; 81 FR 56787 through 56872; and 82 FR 38010 through 38085, respectively). C. Adoption of the MS-DRGs in FY 2008 For information on the adoption of the MS-DRGs in FY 2008, we refer readers to the FY 2008 IPPS final rule with comment period (72 FR 47140 through 47189). D. FY 2019 MS-DRG Documentation and Coding Adjustment 1. Background on the Prospective MS-DRG Documentation and Coding Adjustments for FY 2008 and FY 2009 Authorized by Public Law 110-90 and the Recoupment or Repayment Adjustment Authorized by Section 631 of the American Taxpayer Relief Act of 2012 (ATRA) In the FY 2008 IPPS final rule with comment period (72 FR 47140 through 47189), we adopted the MS-DRG patient classification system for the IPPS, effective October 1, 2007, to better recognize severity of illness in Medicare payment rates for acute care hospitals. The adoption of the MS-DRG system resulted in the expansion of the number of DRGs from 538 in FY 2007 to 745 in FY 2008. By increasing the number of MS-DRGs and more fully taking into account patient severity of illness in Medicare payment rates for acute care hospitals, MS-DRGs encourage hospitals to improve their documentation and coding of patient diagnoses. In the FY 2008 IPPS final rule with comment period (72 FR 47175 through 47186), we indicated that the adoption of the MS-DRGs had the potential to lead to increases in aggregate payments without a corresponding increase in actual patient severity of illness due to the incentives for additional documentation and coding. In that final rule with comment period, we exercised our authority under section 1886(d)(3)(A)(vi) of the Act, which authorizes us to maintain budget neutrality by adjusting the national standardized amount, to eliminate the estimated effect of changes in coding or classification that do not reflect real changes in case-mix. Our actuaries estimated that maintaining budget neutrality required an adjustment of -4.8 percentage points to the national standardized amount. We provided for phasing in this -4.8 percentage point adjustment over 3 years. Specifically, we established prospective documentation and coding adjustments of -1.2 percentage points for FY 2008, -1.8 percentage points for FY 2009, and -1.8 percentage points for FY 2010. On September 29, 2007, Congress enacted the TMA [Transitional Medical Assistance], Abstinence Education, and QI [Qualifying Individuals] Programs Extension Act of 2007 (Pub. L. 110-90). Section 7(a) of Public Law 110-90 reduced the documentation and coding adjustment made as a result of the MS-DRG system that we adopted in the FY 2008 IPPS final rule with comment period to -0.6 percentage point for FY 2008 and -0.9 percentage point for FY 2009. As discussed in prior year rulemakings, and most recently in the FY 2017 IPPS/LTCH PPS final rule (81 FR 56780 through 56782), we implemented a series of adjustments required under sections 7(b)(1)(A) and 7(b)(1)(B) of Public Law 110-90, based on a retrospective review of FY 2008 and FY 2009 claims data. We completed these adjustments in FY 2013 but indicated in the FY 2013 IPPS/LTCH PPS final rule (77 FR 53274 through 53275) that delaying full implementation of the adjustment required under section 7(b)(1)(A) of Public Law 110-90 until FY 2013 resulted in payments in FY 2010 through FY 2012 being overstated, and that these overpayments could not be recovered under Public Law 110-90. In addition, as discussed in prior rulemakings and most recently in the FY 2018 IPPS/LTCH PPS final rule (82 FR 38008 through 38009), section 631 of the ATRA amended section 7(b)(1)(B) of Public Law 110-90 to require the Secretary to make a recoupment adjustment or adjustments totaling $11 billion by FY 2017. This adjustment represented the amount of the increase in aggregate payments as a result of not completing the prospective adjustment authorized under section 7(b)(1)(A) of Public Law 110-90 until FY 2013. 2. Adjustment Made for FY 2018 as Required Under Section 414 of Public Law 114-10 (MACRA) and Section 15005 of Public Law 114-255 As stated in the FY 2017 IPPS/LTCH PPS final rule (81 FR 56785), once the recoupment required under section 631 of the ATRA was complete, we had anticipated making a single positive adjustment in FY 2018 to offset the reductions required to recoup the $11 billion under section 631 of the ATRA. However, section 414 of the MACRA (which was enacted on April 16, 2015) replaced the single positive adjustment we intended to make in FY 2018 with a 0.5 percentage point positive adjustment for each of FYs 2018 through 2023. In the FY 2017 rulemaking, we indicated that we would address the adjustments for FY 2018 and later fiscal years in future rulemaking. Section 15005 of the 21st Century Cures Act (Pub. L. 114-255), which was enacted on December 13, 2016, amended section 7(b)(1)(B) of the TMA, as amended by section 631 of the ATRA and section 414 of the MACRA, to reduce the [[Page 41157]] adjustment for FY 2018 from a 0.5 percentage point to a 0.4588 percentage point. As we discussed in the FY 2018 rulemaking, we believe the directive under section 15005 of Public Law 114-255 is clear. Therefore, in the FY 2018 IPPS/LTCH PPS final rule (82 FR 38009) for FY 2018, we implemented the required +0.4588 percentage point adjustment to the standardized amount. This is a permanent adjustment to payment rates. While we did not address future adjustments required under section 414 of the MACRA and section 15005 of Public Law 114-255 at that time, we stated that we expected to propose positive 0.5 percentage point adjustments to the standardized amounts for FYs 2019 through 2023. 3. Adjustment for FY 2019 In the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20176 and 20177), consistent with the requirements of section 414 of the MACRA, we proposed to implement a positive 0.5 percentage point adjustment to the standardized amount for FY 2019. We indicated that this would be a permanent adjustment to payment rates. We stated in the proposed rule that we plan to propose future adjustments required under section 414 of the MACRA for FYs 2020 through 2023 in future rulemaking. Comment: Several commenters stated that CMS has misinterpreted the Congressional directives regarding the level of positive adjustment required for FY 2018 and FY 2019. The commenters contended that, while the positive adjustments required under section 414 of the MACRA would only total 3.0 percentage points by FY 2023, the levels of these adjustments were determined using an estimated positive ``3.2 percent baseline'' adjustment that otherwise would have been made in FY 2018. The commenters believed that because CMS implemented an adjustment of - 1.5 percentage points instead of the expected -0.8 percentage points in FY 2017, totaling -3.9 percentage points overall, CMS has imposed a permanent -0.7 percentage point negative adjustment beyond its statutory authority, contravening what the commenters asserted was Congress' clear instructions and intent. A majority of the commenters requested that CMS reverse its previous position and implement additional 0.7 percentage point adjustments for both FY 2018 and FY 2019. Some of the commenters requested that CMS use its statutory discretion to ensure that all 3.9 percentage points in negative adjustment be restored. In addition, some of the commenters, while acknowledging that CMS may be bound by law, expressed opposition to the permanent reductions and requested that CMS refrain from making any additional coding adjustments in the future. Response: As we discussed in the FY 2019 IPPS/LTCH PPS proposed rule, we believe section 414 of the MACRA and section 15005 of the 21st Century Cures Act clearly set forth the levels of positive adjustments for FYs 2018 through 2023. We are not convinced that the adjustments prescribed by MACRA were predicated on a specific ``baseline'' adjustment level. While we had anticipated making a positive adjustment in FY 2018 to offset the reductions required to recoup the $11 billion under section 631 of the ATRA, section 414 of the MACRA required that we implement a 0.5 percentage point positive adjustment for each of FYs 2018 through 2023, and not the single positive adjustment we intended to make in FY 2018. As noted by the commenters, and discussed in the FY 2017 IPPS/LTCH PPS final rule, by phasing in a total positive adjustment of only 3.0 percentage points, section 414 of the MACRA would not fully restore even the 3.2 percentage points adjustment originally estimated by CMS in the FY 2014 IPPS/LTCH PPS final rule (78 FR 50515). Moreover, as discussed in the FY 2018 IPPS/LTCH PPS final rule, Public Law 114-255, which further reduced the positive adjustment required for FY 2018 from 0.5 percentage point to 0.4588 percentage point, was enacted on December 13, 2016, after CMS had proposed and finalized the final negative -1.5 percentage points adjustment required under section 631 of the ATRA. We see no evidence that Congress enacted these adjustments with the intent that CMS would make an additional +0.7 percentage point adjustment in FY 2018 to compensate for the higher than expected final ATRA adjustment made in FY 2017. After consideration of the public comments we received, we are finalizing the +0.5 percentage point adjustment to the standardized amount for FY 2019, as required under section 414 of the MACRA. E. Refinement of the MS-DRG Relative Weight Calculation 1. Background Beginning in FY 2007, we implemented relative weights for DRGs based on cost report data instead of charge information. We refer readers to the FY 2007 IPPS final rule (71 FR 47882) for a detailed discussion of our final policy for calculating the cost-based DRG relative weights and to the FY 2008 IPPS final rule with comment period (72 FR 47199) for information on how we blended relative weights based on the CMS DRGs and MS-DRGs. We also refer readers to the FY 2017 IPPS/ LTCH PPS final rule (81 FR 56785 through 56787) for a detailed discussion of the history of changes to the number of cost centers used in calculating the DRG relative weights. Since FY 2014, we have calculated the IPPS MS-DRG relative weights using 19 CCRs, which now include distinct CCRs for implantable devices, MRIs, CT scans, and cardiac catheterization. 2. Discussion of Policy for FY 2019 Consistent with our established policy, we calculated the final MS- DRG relative weights for FY 2019 using two data sources: the MedPAR file as the claims data source and the HCRIS as the cost report data source. We adjusted the charges from the claims to costs by applying the 19 national average CCRs developed from the cost reports. The description of the calculation of the 19 CCRs and the MS-DRG relative weights for FY 2019 is included in section II.G. of the preamble to this FY 2019 IPPS/LTCH PPS final rule. As we did with the FY 2018 IPPS/ LTCH PPS final rule, for this FY 2019 final rule, we are providing the version of the HCRIS from which we calculated these 19 CCRs on the CMS website at: http://www.cms.gov/Medicare/Medicare-Fee-for-Service-Payment/AcuteInpatientPPS/index.html. Click on the link on the left side of the screen titled ``FY 2019 IPPS Final Rule Home Page'' or ``Acute Inpatient Files for Download.'' Comment: One commenter requested that CMS use a single diagnostic radiology CCR to set weights, rather than using the separate CT and MRI cost centers. The commenter requested that if CMS maintains the separate CT and MRI cost centers, CMS not include cost reports from hospitals that use the ``square foot'' allocation methodology. The commenter provided an analysis to support its assertion that the CCRs for CT and MRI are incorrect and are inappropriately reducing payments under the IPPS. The commenter indicated that the charge compression hypothesis has been shown to be false with the use of the separate CT and MRI cost centers. The commenter discussed problems with cost allocation to the CT and MRI cost centers and referenced discussions in prior IPPS/LTCH PPS rules about this issue. The commenter acknowledged that CMS did not include a specific proposal in the FY 2019 proposed rule regarding this issue. [[Page 41158]] Response: As the commenter noted, we did not make any proposal for FY 2019 relating to the number of cost centers used to calculate the relative weights. As noted previously and discussed in detail in prior rulemakings, and as noted in response to a similar public comment received last year, we have calculated the IPPS MS-DRG relative weights using 19 CCRs, including distinct CCRs for MRIs and CT scans, since FY 2014. We refer readers to the FY 2017 IPPS/LTCH PPS final rule (81 FR 56785) for a detailed discussion of the basis for establishing these 19 CCRs. We further note that in the FY 2014 IPPS/LTCH PPS final rule (78 FR 50518 through 50523), we presented data analyses using distinct CCRs for implantable devices, MRIs, CT scans, and cardiac catheterization. We will continue to explore ways in which we can improve the accuracy of the cost report data and calculated CCRs used in the cost estimation process. F. Changes to Specific MS-DRG Classifications 1. Discussion of Changes to Coding System and Basis for FY 2019 MS-DRG Updates a. Conversion of MS-DRGs to the International Classification of Diseases, 10th Revision (ICD-10) As of October 1, 2015, providers use the International Classification of Diseases, 10th Revision (ICD-10) coding system to report diagnoses and procedures for Medicare hospital inpatient services under the MS-DRG system instead of the ICD-9-CM coding system, which was used through September 30, 2015. The ICD-10 coding system includes the International Classification of Diseases, 10th Revision, Clinical Modification (ICD-10-CM) for diagnosis coding and the International Classification of Diseases, 10th Revision, Procedure Coding System (ICD-10-PCS) for inpatient hospital procedure coding, as well as the ICD-10-CM and ICD-10-PCS Official Guidelines for Coding and Reporting. For a detailed discussion of the conversion of the MS-DRGs to ICD-10, we refer readers to the FY 2017 IPPS/LTCH PPS final rule (81 FR 56787 through 56789). b. Basis for FY 2019 MS-DRG Updates CMS has previously encouraged input from our stakeholders concerning the annual IPPS updates when that input was made available to us by December 7 of the year prior to the next annual proposed rule update. As discussed in the FY 2018 IPPS/LTCH PPS final rule (82 FR 38010), as we work with the public to examine the ICD-10 claims data used for updates to the ICD-10 MS DRGs, we would like to examine areas where the MS-DRGs can be improved, which will require additional time for us to review requests from the public to make specific updates, analyze claims data, and consider any proposed updates. Given the need for more time to carefully evaluate requests and propose updates, we changed the deadline to request updates to the MS-DRGs to November 1 of each year. This will provide an additional 5 weeks for the data analysis and review process. Interested parties had to submit any comments and suggestions for FY 2019 by November 1, 2017, and are encouraged to submit any comments and suggestions for FY 2020 by November 1, 2018 via the CMS MS-DRG Classification Change Request Mailbox located at: [email protected]. The comments that were submitted in a timely manner for FY 2019 are discussed in this section of the preamble of this final rule. Following are the changes that we proposed to the MS-DRGs for FY 2019 in the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20177 through 20257). We invited public comments on each of the MS-DRG classification proposed changes, as well as our proposals to maintain certain existing MS-DRG classifications discussed in the proposed rule. In some cases, we proposed changes to the MS-DRG classifications based on our analysis of claims data and consultation with our clinical advisors. In other cases, we proposed to maintain the existing MS-DRG classifications based on our analysis of claims data and consultation with our clinical advisors. For the FY 2019 IPPS/LTCH PPS proposed rule, our MS-DRG analysis was based on ICD-10 claims data from the September 2017 update of the FY 2017 MedPAR file, which contains hospital bills received through September 30, 2017, for discharges occurring through September 30, 2017. In our discussion of the proposed MS-DRG reclassification changes, we referred to our analysis of claims data from the ``September 2017 update of the FY 2017 MedPAR file.'' In this FY 2019 IPPS/LTCH PPS final rule, we summarize the public comments we received on our proposals, present our responses, and state our final policies. For this FY 2019 final rule, we did not perform any further MS-DRG analysis of claims data. Therefore, all of the data analysis is based on claims data from the September 2017 update of the FY 2017 MedPAR file, which contains bills received through September 30, 2017, for discharges occurring through September 30, 2017. As explained in previous rulemaking (76 FR 51487), in deciding whether to propose to make further modifications to the MS-DRGs for particular circumstances brought to our attention, we consider whether the resource consumption and clinical characteristics of the patients with a given set of conditions are significantly different than the remaining patients represented in the MS-DRG. We evaluate patient care costs using average costs and lengths of stay and rely on the judgment of our clinical advisors to determine whether patients are clinically distinct or similar to other patients represented in the MS-DRG. In evaluating resource costs, we consider both the absolute and percentage differences in average costs between the cases we select for review and the remainder of cases in the MS-DRG. We also consider variation in costs within these groups; that is, whether observed average differences are consistent across patients or attributable to cases that are extreme in terms of costs or length of stay, or both. Further, we consider the number of patients who will have a given set of characteristics and generally prefer not to create a new MS-DRG unless it would include a substantial number of cases. In our examination of the claims data, we apply the following criteria established in FY 2008 (72 FR 47169) to determine if the creation of a new complication or comorbidity (CC) or major complication or comorbidity (MCC) subgroup within a base MS-DRG is warranted: A reduction in variance of costs of at least 3 percent; At least 5 percent of the patients in the MS-DRG fall within the CC or MCC subgroup; At least 500 cases are in the CC or MCC subgroup; There is at least a 20-percent difference in average costs between subgroups; and There is a $2,000 difference in average costs between subgroups. In order to warrant creation of a CC or MCC subgroup within a base MS-DRG, the subgroup must meet all five of the criteria. We are making the FY 2019 ICD-10 MS-DRG GROUPER and Medicare Code Editor (MCE) Software Version 36, the ICD-10 MS-DRG Definitions Manual files Version 36 and the Definitions of Medicare Code Edits Manual Version 36 available to the public on our CMS website at: https:// www.cms.gov/Medicare/Medicare-Fee-for-Service- [[Page 41159]] Payment/AcuteInpatientPPS/MS-DRG-Classifications-and-Software.html. 2. Pre-MDC a. Heart Transplant or Implant of Heart Assist System In the FY 2018 IPPS/LTCH PPS final rule (82 FR 38012), we stated our intent to review the ICD-10 logic for Pre-MDC MS-DRGs 001 and 002 (Heart Transplant or Implant of Heart Assist System with and without MCC, respectively), as well as MS-DRG 215 (Other Heart Assist System Implant) and MS-DRGs 268 and 269 (Aortic and Heart Assist Procedures Except Pulsation Balloon with and without MCC, respectively) where procedures involving heart assist devices are currently assigned. We also encouraged the public to submit any comments on restructuring the MS-DRGs for heart assist system procedures to the CMS MS-DRG Classification Change Request Mailbox located at: [email protected] by November 1, 2017. As discussed in the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20178 through 20179), the logic for Pre-MDC MS-DRGs 001 and 002 is comprised of two lists. The first list includes procedure codes identifying a heart transplant procedure, and the second list includes procedure codes identifying the implantation of a heart assist system. The list of procedure codes identifying the implantation of a heart assist system includes the following three codes. ------------------------------------------------------------------------ ICD-10-PCS code Code description ------------------------------------------------------------------------ 02HA0QZ................... Insertion of implantable heart assist system into heart, open approach. 02HA3QZ................... Insertion of implantable heart assist system into heart, percutaneous approach. 02HA4QZ................... Insertion of implantable heart assist system into heart, percutaneous endoscopic approach. ------------------------------------------------------------------------ In addition to these three procedure codes, there are also 33 pairs of code combinations or procedure code ``clusters'' that, when reported together, satisfy the logic for assignment to MS-DRGs 001 and 002. The code combinations are represented by two procedure codes and include either one code for the insertion of the device with one code for removal of the device or one code for the revision of the device with one code for the removal of the device. The 33 pairs of code combinations are listed below. ---------------------------------------------------------------------------------------------------------------- Code Code description Code Code description ---------------------------------------------------------------------------------------------------------------- 02HA0RS..................

Similar to the discussion in the FY 2018 IPPS/LTCH PPS final rule (82 FR 38011 through 38012) involving MS-DRG 215 (Other Heart Assist System Implant), the commenters provided examples of common clinical scenarios involving a left ventricular assist device (LVAD) and included the procedure codes that were reported under the ICD-9 based MS-DRGs in comparison to the procedure codes reported under the ICD-10 MS-DRGs, which are reflected in the following table. ---------------------------------------------------------------------------------------------------------------- ICD-9-CM procedure Procedure code ICD-9 MS-DRG ICD-10-PCS codes ICD-10 MS-DRG ---------------------------------------------------------------------------------------------------------------- New LVAD inserted................ 37.66 (Insertion of 001 or 002 02WA0QZ (Insertion of 001 or 002 implantable heart implantable heart assist system). assist system into heart, open approach). 02WA3QZ (Insertion of implantable heart assist system into heart, percutaneous approach). 02WA4QZ (Insertion of implantable heart assist system into heart, percutaneous endoscopic approach).

Although the commenters recommended that CMS maintain the current logic under the Pre-MDC MS- DRGs 001 and 002, they also recommended that CMS continue to monitor the data in these MS-DRGs for future consideration of distinctions (for example, different approaches and evolving technologies) that may impact the clinical and resource use of patients undergoing procedures utilizing heart assist devices. The commenters also requested that coding guidance be issued for assignment of the correct ICD-10-PCS procedure codes describing LVAD exchanges to encourage accurate reporting of these procedures. In the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20180), we stated that we agree with the commenters that we should continue to monitor the data in Pre-MDC MS-DRGs 001 and 002 for future consideration of distinctions (for example, different approaches and evolving technologies) that may impact the clinical and resource use of patients undergoing procedures utilizing heart assist devices. In response to the request that coding guidance be issued for assignment of the correct ICD-10-PCS procedure codes describing LVAD exchanges to encourage accurate reporting of these procedures, as we noted in the FY 2018 IPPS/LTCH PPS final rule (82 FR 38012), coding advice is issued independently from payment policy. We also noted that, historically, we have not provided coding advice in rulemaking with respect to policy (82 FR 38045). We collaborate with the American Hospital Association (AHA) through the Coding Clinic for ICD-10-CM and ICD-10-PCS to promote proper coding. We recommended that the requestor and other interested parties submit any questions pertaining to correct coding for these technologies to the AHA. In response to the public comments we received on this topic, in the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20180), we provided the results of our claims analysis from the September 2017 update of the FY 2017 MedPAR file for cases in Pre-MDC MS-DRGs 001 and 002. Our findings are shown in the following table. MS-DRGs for Heart Transplant or Implant of Heart Assist System ---------------------------------------------------------------------------------------------------------------- Number of Average length MS-DRG cases of stay Average costs ---------------------------------------------------------------------------------------------------------------- MS-DRG 001--All cases........................................... 1,993 35.6 $185,660 MS-DRG 002--All cases........................................... 179 18.3 99,635 ---------------------------------------------------------------------------------------------------------------- As shown in this table, for MS-DRG 001, there were a total of 1,993 cases with an average length of stay of 35.6 days and average costs of $185,660. For MS-DRG 002, there were a total of 179 cases with an average length of stay of 18.3 days and average costs of $99,635. We then examined claims data in Pre-MDC MS-DRGs 001 and 002 for cases that reported one of the three procedure codes identifying the implantation of a heart assist system such as the LVAD. Our findings are shown in the following table. MS-DRGs for Heart Transplant or Implant of Heart Assist System ---------------------------------------------------------------------------------------------------------------- Number of Average length MS-DRG cases of stay Average costs ---------------------------------------------------------------------------------------------------------------- MS-DRG 001--All cases........................................... 1,993 35.6 $185,660 [[Page 41162]] MS-DRG 001--Cases with procedure code 02HA0QZ (Insertion of 1,260 35.5 206,663 implantable heart assist system into heart, open approach).....

There was one case that reported procedure code 02HA3QZ (Insertion of implantable heart assist system into heart, percutaneous approach) with an average length of stay of 8 days and average costs of $33,889. There were no cases reporting procedure code 02HA4QZ (Insertion of implantable heart assist system into heart, percutaneous endoscopic approach). For MS-DRG 002, there were a total of 82 cases reporting procedure code 02HA0QZ (Insertion of implantable heart assist system into heart, open approach) with an average length of stay of 19.9 days and average costs of $131,957. There were no cases reporting procedure codes 02HA3QZ (Insertion of implantable heart assist system into heart, percutaneous approach) or 02HA4QZ (Insertion of implantable heart assist system into heart, percutaneous endoscopic approach). We also examined the cases in MS-DRGs 001 and 002 that reported one of the possible 33 pairs of code combinations or clusters. Our findings are shown in the following 8 tables. The first table provides the total number of cases reporting a procedure code combination (or cluster) compared to all of the cases in the respective MS-DRG, followed by additional detailed tables showing the number of cases, average length of stay, and average costs for each specific code combination that was reported in the claims data.

In the FY 2019 IPPS/LTCH PPS proposed rule, we agreed with the commenters' recommendation to maintain the structure of Pre-MDC MS-DRGs 001 and 002 for FY 2019 and stated that we would continue to analyze the claims data. Comment: Commenters supported CMS' proposal to maintain the current structure of Pre-MDC MS-DRGs 001 and 002 for FY 2019, and to continue to analyze claims data for consideration of [[Page 41165]] future modifications. The commenters agreed with CMS that current claims data do not yet reflect recent advice published in Coding Clinic for ICD-10-CM/PCS regarding the coding of procedures involving external heart assist devices or recent changes to ICD-10-PCS codes for these procedures. Response: We appreciate the commenters' support. After consideration of the public comments we received, we are maintaining the current structure of Pre-MDC MS-DRGs 001 and 002 for FY 2019. Commenters also suggested that CMS maintain the current logic for MS-DRG 215 (Other Heart Assist System Implant), but they recommended that CMS continue to monitor the data in MS-DRG 215 for future consideration of distinctions (for example, different approaches and evolving technologies) that may impact the clinical and resource use of procedures utilizing heart assist devices. As discussed in the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20184), we also received a request to review claims data for procedures involving extracorporeal membrane oxygenation (ECMO) in combination with the insertion of a percutaneous short-term external heart assist device to determine if the current MS- DRG assignment is appropriate. The logic for MS-DRG 215 is comprised of the procedure codes shown in the following table, for which we examined claims data in the September 2017 update of the FY 2017 MedPAR file in response to the commenters' requests. Our findings are shown in the following table. MS-DRG 215 [Other Heart Assist System Implant] ---------------------------------------------------------------------------------------------------------------- Number of Average length cases of stay Average costs ---------------------------------------------------------------------------------------------------------------- All cases....................................................... 3,428 8.7 $68,965 Cases with procedure code 02HA0RJ (Insertion of short-term 0 0 0 external heart assist system into heart, intraoperative, open approach)......................................................

Cases with procedure code 02WA4RS (Revision of biventricular 0 0 0 short-term external heart assist system in heart, percutaneous endoscopic approach)........................................... Cases with procedure code 02WA4RZ (Revision of short-term 0 0 0 external heart assist system in heart, percutaneous endoscopic approach)...................................................... ---------------------------------------------------------------------------------------------------------------- As shown in this table, for MS-DRG 215, we found a total of 3,428 cases with an average length of stay of 8.7 days and average costs of $68,965. For procedure codes describing the insertion of a biventricular short-term external heart assist system with open, percutaneous or percutaneous endoscopic approaches, we found a total of 127 cases with an average length of stay ranging from 2 to 10 days and average costs ranging from $43,988 to $118,361. For procedure codes describing the insertion of a short-term external heart assist system with open, percutaneous or percutaneous endoscopic approaches, we found a total of 3,233 cases with an average length of stay ranging from 5.3 days to 11.5 days and average costs ranging from $57,042 to $99,107. For procedure codes describing the revision of a short-term external heart assist system with open or percutaneous approaches, we found a total of 88 cases with an average length of stay ranging from 10 to 13.5 days and average costs ranging from $71,077 to $99,378. We found 1 case [[Page 41166]] reporting procedure code 02WA0JZ (Revision of synthetic substitute in heart, open approach), with an average length of stay of 84 days and average costs of $366,089. Lastly, we found 56 cases reporting procedure code 02WA0QZ (Revision of implantable heart assist system in heart, open approach) with an average length of stay of 25.1 days and average costs of $123,410. As the data show, there is a wide range in the average length of stay and the average costs for cases reporting procedures that involve a biventricular short-term external heart assist system versus a short- term external heart assist system. There is an even greater range in the average length of stay and the average costs when comparing the revision of a short-term external heart assist system to the revision of a synthetic substitute in the heart or to the revision of an implantable heart assist system. In the proposed rule, we stated that we agreed with the commenters that continued monitoring of the data and further analysis is necessary prior to proposing any modifications to MS-DRG 215. As stated in the FY 2018 IPPS/LTCH PPS final rule (82 FR 38012), we are aware that the AHA published Coding Clinic advice that clarified coding and reporting for certain external heart assist devices due to the technology being approved for new indications. The current claims data do not yet reflect that updated guidance. We also noted that there have been recent updates to the descriptions of the codes for heart assist devices in the past year. For example, the qualifier ``intraoperative'' was added effective October 1, 2017 (FY 2018) to the procedure codes describing the insertion of short-term external heart assist system procedures to distinguish between procedures where the device was only used intraoperatively and was removed at the conclusion of the procedure versus procedures where the device was not removed at the conclusion of the procedure and for which that qualifier would not be reported. The current claims data do not yet reflect these new procedure codes, which are displayed in the following table and are assigned to MS-DRG 215. ------------------------------------------------------------------------ ICD-10-PCS code Code description ------------------------------------------------------------------------ 02HA0RJ................... Insertion of short-term external heart assist system into heart, intraoperative, open approach. 02HA3RJ................... Insertion of short-term external heart assist system into heart, intraoperative, percutaneous approach. 02HA4RJ................... Insertion of short-term external heart assist system into heart, intraoperative, percutaneous endoscopic approach. ------------------------------------------------------------------------ In the proposed rule, we indicated that our clinical advisors also agreed that additional claims data are needed for analysis prior to proposing any changes to MS-DRG 215. Therefore, we did not propose to make any modifications to MS-DRG 215 for FY 2019. Comment: Commenters supported CMS' proposal to not make any modifications to MS-DRG 215 for FY 2019 and supported continued analysis of claims data for consideration of modifications in future rulemaking. The commenters noted that the proposal was reasonable, given the data, the ICD-10-PCS procedure codes, and information provided. Response: We appreciate the commenters' support. After consideration of the public comments we received, we are finalizing our proposal to maintain the current structure of MS-DRG 215 for FY 2019. As stated in the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20185) and earlier in this section, we also received a request to review cases reporting the use of ECMO in combination with the insertion of a percutaneous short-term external heart assist device. Under ICD-10-PCS, ECMO is identified with procedure code 5A15223 (Extracorporeal membrane oxygenation, continuous) and the insertion of a percutaneous short-term external heart assist device is identified with procedure code 02HA3RZ (Insertion of short-term external heart assist system into heart, percutaneous approach). According to the commenter, when ECMO procedures are performed percutaneously, they are less invasive and less expensive than traditional ECMO. The commenter also noted that, currently under ICD-10-PCS, there is not a specific procedure code to identify percutaneous ECMO, and providers are only able to report ICD- 10-PCS procedure code 5A15223, which may be inappropriately resulting in a higher paying MS-DRG. Therefore, the commenter submitted a separate request to create a new ICD-10-PCS procedure code specifically for percutaneous ECMO which was discussed at the March 6-7, 2018 ICD-10 Coordination and Maintenance Committee Meeting. We refer readers to section II.F.18. of the preamble of this final rule for further information regarding this meeting and the discussion for a new procedure code. The requestor suggested that cases reporting a procedure code for ECMO in combination with the insertion of a percutaneous short-term external heart assist device could be reassigned from Pre-MDC MS-DRG 003 (ECMO or Tracheostomy with Mechanical Ventilation >96 Hours or Principal Diagnosis Except Face, Mouth and Neck with Major O.R. Procedure) to MS-DRG 215. Our analysis involved examining cases in Pre- MDC MS-DRG 003 in the September 2017 update of the FY 2017 MedPAR file for cases reporting ECMO with and without the insertion of a percutaneous short-term external heart assist device. Our findings are shown in the following table. ECMO and Percutaneous Short-Term External Heart Assist Device ---------------------------------------------------------------------------------------------------------------- Number of Average length Pre-MDC MS-DRG cases of stay Average costs ---------------------------------------------------------------------------------------------------------------- MS-DRG 003--All cases........................................... 14,383 29.5 $118,218 MS-DRG 003--Cases with procedure code 5A15223 (Extracorporeal 1,786 19 119,340 membrane oxygenation, continuous).............................. MS-DRG 003--Cases with procedure code 5A15223 (Extracorporeal 94 11.4 110,874 membrane oxygenation, continuous) and 02HA3RZ (Insertion of short-term external heart assist system into heart, percutaneous approach)......................................... [[Page 41167]] MS-DRG 003--Cases with procedure code 5A15223 (Extracorporeal 1 1 64,319 membrane oxygenation, continuous) and 02HA4RZ (Insertion of short-term external heart assist system into heart, percutaneous endoscopic approach).............................. ---------------------------------------------------------------------------------------------------------------- As shown in this table, we found a total of 14,383 cases with an average length of stay of 29.5 days and average costs of $118,218 in Pre-MDC MS-DRG 003. We found 1,786 cases reporting procedure code 5A15223 (Extracorporeal membrane oxygenation, continuous) with an average length of stay of 19 days and average costs of $119,340. We found 94 cases reporting procedure code 5A15223 and 02HA3RZ (Insertion of short-term external heart assist system into heart, percutaneous approach) with an average length of stay of 11.4 days and average costs of $110,874. Lastly, we found 1 case reporting procedure code 5A15223 and 02HA4RZ (Insertion of short-term external heart assist system into heart, percutaneous endoscopic approach) with an average length of stay of 1 day and average costs of $64,319. We also reviewed the cases in MS-DRG 215 for procedure codes 02HA3RZ and 02HA4RZ. Our findings are shown in the following table. Percutaneous Short-Term External Heart Assist Device ---------------------------------------------------------------------------------------------------------------- Number of Average length MS-DRG cases of stay Average costs ---------------------------------------------------------------------------------------------------------------- MS-DRG 215--All cases........................................... 3,428 8.7 $68,965 MS-DRG 215--Cases with procedure code 02HA3RZ (Insertion of 3,136 8.4 67,670 short-term external heart assist system into heart, percutaneous approach)......................................... MS-DRG 215--Cases with procedure code 02HA4RZ (Insertion of 31 5.3 57,042 short-term external heart assist system into heart, percutaneous endoscopic approach).............................. ---------------------------------------------------------------------------------------------------------------- As shown in this table, we found a total of 3,428 cases with an average length of stay of 8.7 days and average costs of $68,965. We found a total of 3,136 cases reporting procedure code 02HA3RZ with an average length of stay of 8.4 days and average costs of $67,670. We found a total of 31 cases reporting procedure code 02HA4RZ with an average length of stay of 5.3 days and average costs of $57,042. We stated in the proposed rule that, for Pre-MDC MS-DRG 003, while the average length of stay and average costs for cases where procedure code 5A15223 was reported with procedure code 02HA3RZ or procedure code 02HA4RZ are lower than the average length of stay and average costs for cases where procedure code 5A15223 was reported alone, we are unable to determine from the data if those ECMO procedures were performed percutaneously in the absence of a unique code. In addition, the one case reporting procedure code 5A15223 with 02HA4RZ only had a 1 day length of stay and it is unclear from the data what the circumstances of that case may have involved. For example, the patient may have been transferred or may have expired. Therefore, in the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20186), we proposed to not reassign cases reporting procedure code 5A15223 when reported with procedure code 02HA3RZ or procedure code 02HA4RZ for FY 2019. We stated in the proposed rule that our clinical advisors agreed that until there is a way to specifically identify percutaneous ECMO in the claims data to enable further analysis, a proposal at this time is not warranted. Comment: Commenters supported CMS' proposal to not reassign cases reporting the use of ECMO (procedure code 5A15223) in combination with the insertion of a percutaneous short-term external heart assist device (procedure code 02HA3RZ or procedure code 02HA4RZ) for FY 2019. Response: We appreciate the commenters' support. Comment: Other commenters acknowledged that new ICD-10-PCS procedure codes that identify percutaneous ECMO procedures were made publicly available in May 2018. The commenters suggested that the new procedure codes be assigned to MS-DRGs that reflect cases representing patients with similar clinical characteristics and whose treatment requires similar resource utilization, such as MS-DRG 215. Some commenters specifically requested that the new procedure code describing a percutaneous veno-arterial (VA) ECMO procedure be considered for assignment to MS-DRG 215 versus Pre-MDC MS-DRG 003 because MS-DRG 215 is the primary MS-DRG for procedures involving the implantation of peripheral heart assist pumps, with similar cases representing patient conditions and clinical coherence. The commenters noted that the percutaneous ECMO procedure is less invasive and less expensive than the traditional ECMO procedure, and has the clinical similarities and requires similar resource utilization as procedures currently assigned to MS-DRG 215, such as the percutaneous ventricular assist devices procedure. Another commenter suggested that CMS should assign cases representing patients receiving treatment involving the peripheral VA ECMO procedure to MS-DRG 215 or another MS-DRG within MDC 5. The commenter stated that cases representing patients currently assigned to MS-DRG 215 are clinically coherent to the characteristics of the patients who undergo a peripheral VA ECMO procedure. Another commenter recommended that the new procedure code describing a percutaneous veno- venous (VV) ECMO procedure be considered for assignment to MS-DRG 004 or another MS-DRG within MDC 4 because the indication is to provide respiratory support. Response: The commenters are correct that the FY 2019 ICD-10-PCS procedure code files (which are available via the internet on the CMS website at: https://www.cms.gov/Medicare/Coding/ICD10/2019-ICD-10-PCS.html) include new ICD-10-PCS procedure codes that identify percutaneous ECMO procedures. In addition, the files also show that the current code for ECMO [[Page 41168]] procedures (ICD-10-PCS code 5A15223) has been revised. These new procedure codes, and the revised ECMO procedure code and description, effective October 1, 2018, are shown in the following table. ------------------------------------------------------------------------ ICD-10-PCS code Code description ------------------------------------------------------------------------ 5A1522F............................. Extracorporeal Oxygenation, Membrane, Central. 5A1522G............................. Extracorporeal Oxygenation, Membrane, Peripheral Veno- arterial. 5A1522H............................. Extracorporeal Oxygenation, Membrane, Peripheral Veno-venous. ------------------------------------------------------------------------ In response to the commenters' suggestions to assign the new procedure codes for percutaneous ECMO procedures to MS-DRG 215, we note that the new procedure codes created to describe percutaneous ECMO procedures were not finalized at the time of the proposed rule. In addition, the deletion of the current procedure code for ECMO (ICD-10- PCS code 5A15223) and the creation of the new procedure code for central ECMO were not finalized at the time of the proposed rule. As these codes were not finalized at the time of the proposed rule, they were not reflected in Table 6B.--New Procedure Codes (which is available via the internet on the CMS website at: http://www.cms.hhs.gov/Medicare/Medicare-Fee-for-Service-Payment/AcuteInpatientPPS/index.html) associated with the FY 2019 IPPS/LTCH PPS proposed rule. Therefore, because these procedure codes were not yet approved, there were no proposed MDC, MS-DRG, or O.R. and non-O.R. designations for these new procedure codes. Consistent with our annual process of assigning new procedure codes to MDCs and MS-DRGs, and designating a procedure as an O.R. or non-O.R. procedure, we reviewed the predecessor procedure code assignments. The predecessor procedure code (ICD-10-PCS code 5A15223) for the new percutaneous ECMO procedure codes describes an open approach which requires an incision along the sternum (sternotomy) and is performed for open heart surgery. It is considered extremely invasive and carries significant risks for complications, including bleeding, infection, and vessel injury. For central ECMO, arterial cannulation typically occurs directly into the ascending aorta and venous cannulation occurs directly into the right atrium. Conversely, percutaneous (peripheral) ECMO does not require a sternotomy and can be performed in the intensive care unit or at the bedside. The cannulae are placed percutaneously and can utilize a variety of configurations, according to the indication (VA or VV) and patient age (adult vs. pediatric). While percutaneous ECMO also carries risks, they differ from those of central ECMO. For example, our clinical advisor note that patients receiving percutaneous ECMO are at a greater risk of suffering vascular complications. Upon review, our clinical advisors do not support assigning the new procedure codes for peripheral ECMO procedures to the same MS-DRG as the predecessor code for open (central) ECMO in Pre-MDC MS-DRG 003. Our clinical advisors also do not agree with designating percutaneous ECMO procedures as O.R. procedures because they are less resource intensive compared to open ECMO procedures. As shown in Table 6B.--New Procedure Codes associated with this final rule (which is available via the internet on the CMS website at: http://www.cms.hhs.gov/Medicare/Medicare-Fee-for-Service-Payment/AcuteInpatientPPS/index.html), the new procedure codes for percutaneous ECMO procedures have been designated as non-O.R. procedures that will affect the MS-DRG assignment for specific medical MS-DRGs. Effective October 1, 2018, the MS-DRGs for which the percutaneous ECMO procedures will affect MS-DRG assignment are shown in the following table, along with the revised MS-DRG titles. ------------------------------------------------------------------------ MDC MS-DRG MS-DRG title ------------------------------------------------------------------------ 4.......................... 207 Respiratory System Diagnosis with Ventilator Support >96 Hours or Peripheral Extracorporeal Membrane Oxygenation (ECMO). 5.......................... 291 Heart Failure and Shock with MCC or Peripheral Extracorporeal Membrane Oxygenation (ECMO). 5.......................... 296 Cardiac Arrest, Unexplained with MCC or Peripheral Extracorporeal Membrane Oxygenation (ECMO). 18......................... 870 Septicemia or Severe Sepsis with MV >96 Hours or Peripheral Extracorporeal Membrane Oxygenation (ECMO). ------------------------------------------------------------------------ Our clinical advisors support the designation of the peripheral ECMO procedures as a non-O.R. procedure affecting the MS-DRG assignment of MS-DRG 207 because they consider the procedure to be similar to providing mechanical ventilation greater than 96 hours in terms of both clinical severity and resource use. Because any respiratory diagnosis classified under MDC 4 with mechanical ventilation greater than 96 hours is assigned to MS-DRG 207, it is reasonable to expect that any patient with a respiratory diagnosis who requires treatment involving a peripheral ECMO procedure should also be assigned to MS-DRG 207. The same rationale was applied for MS-DRG 870, which also includes mechanical ventilation greater than 96 hours. In addition, based on the common clinical indications for which a percutaneous ECMO procedure is utilized, such as cardiogenic shock and cardiac arrest, our clinical advisors determined that MS-DRGs 291 (Heart Failure and Shock with MCC) and 296 (Cardiac Arrest, Unexplained with MCC) also are appropriate for a percutaneous ECMO procedure to affect the MS-DRG assignment. The MS- DRG assignment for a central ECMO procedure will remain in Pre-MDC MS- DRG 003. In cases where a percutaneous external heart assist device is utilized, in combination with a percutaneous ECMO procedure, effective October 1, 2018, the ICD-10 MS-DRG Version 36 GROUPER logic results in a case assignment to MS-DRG 215 because the percutaneous external heart assist device procedure is designated as an O.R. procedure and assigned to MS-DRG 215. Because the procedure codes describing percutaneous ECMO procedures are new, becoming effective October 1, 2018, we do not yet have any claims data to analyze. Once claims data becomes available, we can examine the [[Page 41169]] volume, and length of stay and cost data to determine if modifications to the assignment of these procedure codes are warranted. After consideration of the public comments we received, we are finalizing our proposal to not reassign cases reporting ICD-10-PCS procedure code 5A15223 when reported with ICD-10-PCS procedure code 02HA3RZ or ICD-10-PCS procedure code 02HA4RZ for FY 2019. Consistent with our policy for determining MS-DRG assignment for new codes and for the reasons discussed, the two new procedure codes describing percutaneous ECMO procedures discussed and displayed in the table above, under the ICD-10 MS-DRGs Version 36 GROUPER logic, effective October 1, 2018, are designated as non-O.R. procedures impacting the MS-DRG assignment of MS-DRGs 207, 291, 296, and 870. The MS-DRG assignment for the central ECMO procedure remains in Pre-MDC MS-DRG 003. In the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20186), we also discussed that a commenter also suggested that CMS maintain the current logic for MS-DRGs 268 and 269 (Aortic and Heart Assist Procedures Except Pulsation Balloon with and without MCC, respectively), but recommended that CMS continue to monitor the data in these MS-DRGs for future consideration of distinctions (for example, different approaches and evolving technologies) that may impact the clinical and resource use of procedures involving heart assist devices. The logic for heart assist system devices in MS-DRGs 268 and 269 is comprised of the procedure codes shown in the following table, for which we examined claims data in the September 2017 update of the FY 2017 MedPAR file in response to the commenter's request. Our findings are shown in the following table. MS-DRGs for Aortic and Heart Assist Procedures Except Pulsation Balloon ---------------------------------------------------------------------------------------------------------------- Number of Average length cases of stay Average costs ---------------------------------------------------------------------------------------------------------------- MS-DRG 268--All cases........................................... 3,798 9.6 $49,122 MS-DRG 268--Cases with procedure code 02PA0QZ (Removal of 16 23.4 79,850 implantable heart assist system from heart, open approach).....

MS-DRG 269--Cases with procedure code 02PA4RZ (Removal of short- 0 0 0 term external heart assist system from heart, percutaneous endoscopic approach)........................................... ---------------------------------------------------------------------------------------------------------------- As shown in this table, for MS-DRG 268, there were a total of 3,798 cases, with an average length of stay of 9.6 days and average costs of $49,122. There were 16 cases reporting procedure code 02PA0QZ (Removal of implantable heart assist system from heart, open approach), with an average length of stay of 23.4 days and average costs of $79,850. There were no cases that reported procedure codes 02PA0RS (Removal of biventricular short-term external heart assist system from heart, open approach), 02PA0RZ (Removal of short-term external heart assist system from heart, open approach), 02PA3RS (Removal of biventricular short- term external heart assist system from heart, percutaneous approach), 02PA4RS (Removal of biventricular short-term external heart assist system from heart, percutaneous endoscopic approach) or 02PA4RZ (Removal of short-term external heart assist system from heart, percutaneous endoscopic approach). There were 28 cases reporting procedure code 02PA3QZ (Removal of implantable [[Page 41170]] heart assist system from heart, percutaneous approach), with an average length of stay of 10.5 days and average costs of $31,797. There were 96 cases reporting procedure code 02PA3RZ (Removal of short-term external heart assist system from heart, percutaneous approach), with an average length of stay of 12.4 days and average costs of $51,469. There were 5 cases reporting procedure code 02PA4QZ (Removal of implantable heart assist system from heart, percutaneous endoscopic approach), with an average length of stay of 7.8 days and average costs of $37,592. For MS-DRG 269, there were a total of 16,900 cases, with an average length of stay of 2.4 days and average costs of $30,793. There were 10 cases reporting procedure code 02PA0QZ (Removal of implantable heart assist system from heart, open approach), with an average length of stay of 8 days and average costs of $23,741. There were no cases reporting procedure codes 02PA0RS (Removal of biventricular short-term external heart assist system from heart, open approach), 02PA0RZ (Removal of short-term external heart assist system from heart, open approach), 02PA3RS (Removal of biventricular short-term external heart assist system from heart, percutaneous approach), 02PA4RS (Removal of biventricular short-term external heart assist system from heart, percutaneous endoscopic approach) or 02PA4RZ (Removal of short-term external heart assist system from heart, percutaneous endoscopic approach). There were 6 cases reporting procedure code 02PA3QZ (Removal of implantable heart assist system from heart, percutaneous approach), with an average length of stay of 5 days and average costs of $19,421. There were 11 cases reporting procedure code 02PA3RZ (Removal of short- term external heart assist system from heart, percutaneous approach), with an average length of stay of 4 days and average costs of $25,719. There was 1 case reporting procedure code 02PA4QZ (Removal of implantable heart assist system from heart, percutaneous endoscopic approach), with an average length of stay of 3 days and average costs of $14,415. The data show that there are differences in the average length of stay and average costs for cases in MS-DRGs 268 and 269 according to the type of device (short-term external heart assist system or implantable heart assist system), and the approaches that were utilized (open, percutaneous, or percutaneous endoscopic). In the proposed rule, we stated that we agreed with the recommendation to maintain the structure of MS-DRGs 268 and 269 for FY 2019 and will continue to analyze the claims data for possible future updates. As such, we proposed to not make any changes to the structure of MS-DRGs 268 and 269 for FY 2019. Comment: Commenters supported CMS' proposal to not make any changes to the structure of MS-DRGs 268 and 269 for FY 2019. Response: We appreciate the commenters' support. After consideration of the public comments we received, we are finalizing our proposal to maintain the structure of MS-DRGs 268 and 269 for FY 2019. b. Brachytherapy As discussed in the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20188), we received a request to create a new Pre-MDC MS-DRG for all procedures involving the CivaSheet[supreg] technology, an implantable, planar brachytherapy source designed to enable delivery of radiation to the site of the cancer tumor excision or debulking, while protecting neighboring tissue. The requestor stated that physicians have used the CivaSheet[supreg] technology for a number of indications, such as colorectal, gynecological, head and neck, soft tissue sarcomas and pancreatic cancer. The requestor noted that potential uses also include nonsmall-cell lung cancer, ocular melanoma, and atypical meningioma. Currently, procedures involving the CivaSheet[supreg] technology are reported using ICD-10-PCS Section D--Radiation Therapy codes, with the root operation ``Brachytherapy.'' These codes are non-O.R. codes and group to the MS-DRG to which the principal diagnosis is assigned. In response to this request, we analyzed claims data from the September 2017 update of the FY 2017 MedPAR file for cases representing patients who received treatment that reported low dose rate (LDR) brachytherapy procedure codes across all MS-DRGs. We referred readers to Table 6P.--ICD-10-CM and ICD-10-PCS Codes for Proposed MS-DRG Changes associated with the proposed rule, which is available via the internet on the CMS website at: https://www.cms.gov/Medicare/Medicare-Fee-for-Service-Payment/AcuteInpatientPPS/index.html. A detailed list of these procedure codes was shown in Table 6P.1.associated with the proposed rule. Our findings are reflected in the following table. As we note below in response to comments, there were errors in the table included in the proposed rule (83 FR 20188) with regard to an identified MS-DRG and procedure code. However, there were no errors in the data findings reported. In the proposed rule, we identified claims data for MS-DRG 129 with procedure code D710BBZ (Low dose rate (LDR) brachytherapy of bone marrow using Palladium-103 (Pd-103)). That entry was an inadventent error. The correct MS-DRG, that is, MS-DRG 054, and procedure code, that is, D010BBZ, are reflected in the table that follows. In addition, in the proposed rule we inadvertently identified MS-DRG 724 with procedure code DV10BBZ (Low dose rate (LDR) brachytherapy of prostate using Palladium 103 (Pd-103)). Upon review, this case was actually reported with MS-DRG 189. The data findings identified for each of these 4 cases are correctly reflected in the table that follows. Cases Reporting Low Dose Rate (LDR) Brachytherapy Procedure Codes Across All MS-DRGs ---------------------------------------------------------------------------------------------------------------- Number of Average length ICD-10-PCS procedures cases of stay Average costs ---------------------------------------------------------------------------------------------------------------- MS-DRG 054 (Nervous System Neoplasms with CC)--Cases with 1 7 $10,357 procedure code D010BBZ (Low dose rate (LDR) brachytherapy of brain using Palladium[dash]103 (Pd-103))....................... MS-DRG 189 (Pulmonary Edema and Respiratory Failure)--Cases with 1 7 32,298 procedure code DV10BBZ (Low dose rate (LDR) brachytherapy of prostate using Palladium[dash]103 (Pd-103)).................... MS-DRG 129 (Major Head and Neck Procedures with CC/MCC or Major 1 3 42,565 Device)--Cases with procedure code DW11BBZ (Low dose rate (LDR) brachytherapy of head and neck using Palladium[dash]103 (Pd- 103)).......................................................... MS-DRG 330 (Major Small and Large Bowel Procedures with CC)-- 1 8 74,190 Cases with procedure code DW16BBZ (Low dose rate (LDR) brachytherapy of pelvic region using Palladium[dash]103 (Pd- 103)).......................................................... ---------------------------------------------------------------------------------------------------------------- [[Page 41171]] As shown in the immediately preceding table, we identified 4 cases reporting one of these LDR brachytherapy procedure codes across all MS- DRGs, with an average length of stay of 6.3 days and average costs of $39,853. In the proposed rule, we stated that we believe that creating a new Pre-MDC MS-DRG based on such a small number of cases could lead to distortion in the relative payment weights for the Pre-MDC MS-DRG. Having a larger number of clinically cohesive cases within the Pre-MDC MS-DRG provides greater stability for annual updates to the relative payment weights. Therefore, we did not propose to create a new Pre-MDC MS-DRG for procedures involving the CivaSheet[supreg] technology for FY 2019. Comment: Some commenters supported CMS' proposal not to create a new MS-DRG for assignment of procedures involving the CivaSheet[supreg] technology. Several commenters, including the manufacturer of the CivaSheet[supreg] technology, disagreed with CMS' proposal, and stated that the current payment for cases involving the CivaSheet[supreg] technology is inadequate and does not currently allow widespread adoption and use of the technology. One commenter noted that its contractor also identified four cases in the proposed rule, but raised some concerns regarding the procedure codes and costs associated with the cases identified in the proposed rule. Other commenters described the clinical benefits and potential cost-savings associated with the CivaSheet[supreg] technology, and requested that CMS reconsider its proposal to not create a new Pre- MDC MS-DRG for the assignment of cases involving the use of this technology. The commenters stated that they understood CMS' concern about the lack of volume, but indicated that the lack of adequate payment for procedures involving the CivaSheet[supreg] technology does not allow more widespread use. The manufacturer requested that, if CMS finalizes its proposal not to create a new MS-DRG for assignment of cases involving the CivaSheet[supreg] technology, CMS consider other payment mechanisms by which to ensure adequate payment for hospitals providing this service. Response: We appreciate the commenters' support and input. With respect to the commenters who disagreed with our proposal, we reiterate that our analysis of the claims data and our clinical advisors did not support the creation of a new MS-DRG based on the very small number of cases identified. As we noted in the proposed rule, only four cases were identified. The MS-DRGs are a classification system intended to group together those diagnoses and procedures with similar clinical characteristics and utilization of resources. As we discussed in the proposed rule, basing a new MS-DRG on such a small number of cases could lead to distortions in the relative payment weights for the MS- DRG because several expensive cases could impact the overall relative payment weight. Having larger clinical cohesive groups within an MS-DRG provides greater stability for annual updates to the relative payment weights. We agree with the commenter that there were some inadvertent errors in the table included in the proposed rule in reference to certain procedure codes and MS-DRGs; the table in this final rule above now correctly reflects the procedure codes and MS-DRGs reflected in the FY 2017 MedPAR file (as of the September 2017 update). We note that because our proposal was based on the small number of cases, and not the nature of those cases, these errors had no bearing on our proposal or our decision to finalize this proposal. We acknowledge the commenters' concerns about the adequacy of payment for these low volume services. Therefore, as part of our ongoing, comprehensive analysis of the MS-DRGs under ICD-10, we will continue to explore mechanisms through which to address rare diseases and low volume DRGs. After consideration of the public comments we received, we are finalizing our proposal to maintain the current MS-DRG structure for procedures involving the CivaSheet[supreg] technology for FY 2019. c. Laryngectomy The logic for case assignment to Pre-MDC MS-DRGs 11, 12, and 13 (Tracheostomy for Face, Mouth and Neck Diagnoses with MCC, with CC, and without CC/MCC, respectively) as displayed in the ICD-10 MS-DRG Version 35 Definitions Manual, which is available via the internet on the CMS website at: https://www.cms.gov/Medicare/Medicare-Fee-for-Service-Payment/AcuteInpatientPPS/FY2018-IPPS-Final-Rule-Home-Page-Items/FY2018-IPPS-Final-Rule-Data-Files.html?DLPage=1&DLEntries=10&DLSort=0&DLSortDir=ascending, is comprised of a list of procedure codes for laryngectomies, a list of procedure codes for tracheostomies, and a list of diagnosis codes for conditions involving the face, mouth, and neck. The procedure codes for laryngectomies are listed separately and are reported differently from the procedure codes listed for tracheostomies. The procedure codes listed for tracheostomies must be reported with a diagnosis code involving the face, mouth, or neck as a principal diagnosis to satisfy the logic for assignment to Pre-MDC MS-DRG 11, 12, or 13. Alternatively, any principal diagnosis code reported with a procedure code from the list of procedure codes for laryngectomies will satisfy the logic for assignment to Pre-MDC MS-DRG 11, 12, or 13. To improve the manner in which the logic for assignment is displayed in the ICD-10 MS-DRG Definitions Manual and to clarify how it is applied for grouping purposes, in the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20188), we proposed to reorder the lists of the diagnosis and procedure codes. The list of principal diagnosis codes for face, mouth, and neck would be sequenced first, followed by the list of the tracheostomy procedure codes and, lastly, the list of laryngectomy procedure codes. We also proposed to revise the titles of Pre-MDC MS-DRGs 11, 12, and 13 from ``Tracheostomy for Face, Mouth and Neck Diagnoses with MCC, with CC and without CC/MCC, respectively'' to ``Tracheostomy for Face, Mouth and Neck Diagnoses or Laryngectomy with MCC'', ``Tracheostomy for Face, Mouth and Neck Diagnoses or Laryngectomy with CC'', and ``Tracheostomy for Face, Mouth and Neck Diagnoses or Laryngectomy without CC/MCC'', respectively, to reflect that laryngectomy procedures may also be assigned to these MS-DRGs. Comment: Commenters supported CMS' proposal to reorder the lists of diagnoses and procedure codes for Pre-MDC MS-DRGs 11, 12 and 13 in the ICD-10 MS-DRG Definitions Manual to clarify the GROUPER logic. The commenters stated that the proposal was reasonable given the ICD-10-CM diagnosis codes, the ICD-10-PCS procedure codes, and the information provided. Commenters also supported the proposal to revise the titles for Pre-MDC MS-DRGs 11, 12 and 13. Response: We appreciate the commenters' support. After consideration of the public comments we received, we are finalizing our proposal to reorder the lists of diagnoses and procedure codes for Pre-MDC MS-DRGs 11, 12, and 13 in the ICD-10 MS-DRG Definitions Manual Version 36. We also are finalizing our proposal to revise the titles for Pre-MDC MS-DRGs 11, 12, and 13 as follows for the ICD-10 MS-DRGs Version 36, effective October 1, 2018: MS-DRG 11 (Tracheostomy for Face, Mouth and Neck Diagnoses or Laryngectomy with MCC); [[Page 41172]] MS-DRG 12 (Tracheostomy for Face, Mouth and Neck Diagnoses or Laryngectomy with CC); and MS-DRG 13 (Tracheostomy for Face, Mouth and Neck Diagnoses or Laryngectomy without CC/MCC). d. Chimeric Antigen Receptor (CAR) T-Cell Therapy Chimeric Antigen Receptor (CAR) T-cell therapy is a cell-based gene therapy in which T-cells are genetically engineered to express a chimeric antigen receptor that will bind to a certain protein on a patient's cancerous cells. The CAR T-cells are then administered to the patient to attack certain cancerous cells and the individual is observed for potential serious side effects that would require medical intervention. Two CAR T-cell therapies received FDA approval in 2017. KYMRIAH[supreg] (manufactured by Novartis Pharmaceuticals Corporation) was approved for the use in the treatment of patients up to 25 years of age with B-cell precursor acute lymphoblastic leukemia (ALL) that is refractory or in second or later relapse. In May 2018, KYMRIAH received FDA approval for a second indication, treatment of adult patients with relapsed or refractory large B-cell lymphoma after two or more lines of systemic therapy, including diffuse large B-cell lymphoma (DLBCL), high grade B-cell lymphoma, and DLBCL arising from follicular lymphoma. YESCARTA[supreg] (manufactured by Kite Pharma, Inc.) was approved for use in the treatment of adult patients with relapsed or refractory large B-cell lymphoma and who have not responded to or who have relapsed after at least two other kinds of treatment. Procedures involving the CAR T-cell therapies are currently identified with ICD-10-PCS procedure codes XW033C3 (Introduction of engineered autologous chimeric antigen receptor t-cell immunotherapy into peripheral vein, percutaneous approach, new technology group 3) and XW043C3 (Introduction of engineered autologous chimeric antigen receptor t-cell immunotherapy into central vein, percutaneous approach, new technology group 3), which both became effective October 1, 2017. Procedures described by these two ICD-10-PCS procedure codes are designated as non-O.R. procedures that have no impact on MS-DRG assignment. As we discussed in the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20189), we have received many inquiries from the public regarding payment of CAR T-cell therapy under the IPPS. Suggestions for the MS- DRG assignment for FY 2019 ranged from assigning ICD-10-PCS procedure codes XW033C3 and XW043C3 to an existing MS-DRG to the creation of a new MS-DRG for CAR T-cell therapy. In the context of the recommendation to create a new MS-DRG for FY 2019, we also received suggestions that payment should be established in a way that promotes comparability between the inpatient setting and outpatient setting. As part of our review of these suggestions, we examined the existing MS-DRGs to identify the MS-DRGs that represent cases most clinically similar to those cases in which the CAR T-cell therapy procedures would be reported. The CAR T-cell procedures involve a type of autologous immunotherapy in which the patient's cells are genetically transformed and then returned to that patient after the patient undergoes cell depleting chemotherapy. Our clinical advisors believe that patients receiving treatment utilizing CAR T-cell therapy procedures would have similar clinical characteristics and comorbidities to those seen in cases representing patients receiving treatment for other hematologic cancers who are treated with autologous bone marrow transplant therapy that are currently assigned to MS-DRG 016 (Autologous Bone Marrow Transplant with CC/MCC). Therefore, after consideration of the inquiries received as to how the IPPS can appropriately group cases reporting the use of CAR T-cell therapy, in the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20189), we proposed to assign ICD-10-PCS procedure codes XW033C3 and XW043C3 to Pre-MDC MS-DRG 016 for FY 2019. In addition, we proposed to revise the title of MS-DRG 016 from ``Autologous Bone Marrow Transplant with CC/MCC'' to ``Autologous Bone Marrow Transplant with CC/MCC or T-cell Immunotherapy.'' However, we noted in the proposed rule that, as discussed in greater detail in section II.H.5.a. of the preamble of the proposed rule and this final rule, the manufacturer of KYMRIAH and the manufacturer of YESCARTA submitted applications for new technology add- on payments for FY 2019. We stated that we also recognize that many members of the public have noted that the combination of the new technology add-on payment applications, the extremely high-cost of these CAR T-cell therapies, and the potential for volume increases over time present unique challenges with respect to the MS-DRG assignment for procedures involving the utilization of CAR T-cell therapies and cases representing patients receiving treatment involving CAR T-cell therapies. We stated in the proposed rule that we believed that, in the context of these pending new technology add-on payment applications, there may also be merit in the alternative suggestion we received to create a new MS-DRG for procedures involving the utilization of CAR T- cell therapies and cases representing patients receiving treatment involving CAR T-cell therapy to which we could assign ICD-10-PCS procedure codes XW033C3 and XW043C3, effective for discharges occurring in FY 2019. We stated that, as noted in section II.H.5.a. of the preamble of the proposed rule, if a new MS-DRG were to be created then consistent with section 1886(d)(5)(K)(ix) of the Act there may no longer be a need for a new technology add-on payment under section 1886(d)(5)(K)(ii)(III) of the Act. We invited public comments on our proposed approach of assigning ICD-10-PCS procedure codes XW033C3 and XW043C3 to Pre-MDC MS-DRG 016 for FY 2019. We also invited public comments on alternative approaches, including in the context of the pending KYMRIAH and YESCARTA new technology add-on payment applications, and the most appropriate way to establish payment for FY 2019 under any alternative approaches. We indicated that such payment alternatives may include using a CCR of 1.0 for charges associated with ICD-10-PCS procedure codes XW033C3 and XW043C3, given that many public inquirers believed that hospitals would be unlikely to set charges different from the costs for KYMRIAH and YESCARTA CAR T-cell therapies, as discussed further in section II.A.4.g.2. of the Addendum of the proposed rule and this final rule. We further stated that these payment alternatives, including payment under any potential new MS-DRG, also could take into account an appropriate portion of the average sales price (ASP) for these drugs, including in the context of the pending new technology add-on payment applications. We invited comments on how these payment alternatives would affect access to care, as well as how they affect incentives to encourage lower drug prices, which is a high priority for this Administration. In addition, we stated that we are considering approaches and authorities to encourage value-based care and lower drug prices. We solicited comments on how the payment methodology alternatives may intersect and affect future participation in any such alternative approaches. We noted that, as stated in section II.F.1.b. of the preamble of the proposed rule, we described the criteria used to establish new MS- DRGs. In particular, [[Page 41173]] we consider whether the resource consumption and clinical characteristics of the patients with a given set of conditions are significantly different than the remaining patients in the MS-DRG. We evaluate patient care costs using average costs and lengths of stay and rely on the judgment of our clinical advisors to decide whether patients are clinically distinct or similar to other patients in the MS-DRG. In evaluating resource costs, we consider both the absolute and percentage differences in average costs between the cases we select for review and the remainder of cases in the MS-DRG. We also consider whether observed average differences are consistent across patients or attributable to cases that were extreme in terms of costs or length of stay, or both. Further, we consider the number of patients who will have a given set of characteristics and generally prefer not to create a new MS-DRG unless it would include a substantial number of cases. Based on the principles typically used to establish a new MS-DRG, we solicited comments on how the administration of the CAR T-cell therapies and associated services meet the criteria for the creation of a new MS-DRG. Also, section 1886(d)(4)(C)(iii) of the Act specifies that, beginning in FY 1991, the annual DRG reclassification and recalibration of the relative weights must be made in a manner that ensures that aggregate payments to hospitals are not affected. Given that a new MS-DRG must be established in a budget neutral manner, we stated that we are concerned with the redistributive effects away from core hospital services over time toward specialized hospitals and how that may affect payment for these core services. Therefore, we solicited public comments on our concerns with the payment alternatives that we were considering for CAR T-cell therapies. Comment: Many commenters stated that the existing payment mechanisms under the IPPS do not allow for accurate payment of CAR T- cell therapy due its unprecedented high cost. Commenters also asserted structural insufficiencies in the new technology add-on payments for the drug therapy, such as the maximum add-on payment of 50 percent; the inapplicability of the usual cost to charge ratios used in ratesetting and payment, including those used in determining new technology add-on payments, outlier payments, and payments to IPPS-excluded cancer hospitals; and a lack of sufficient historical data and experience related to a therapy with a cost of this magnitude. In addition, commenters stated that payment for CAR T-cell therapy should avoid inappropriate financial incentives for care to be provided in an outpatient instead of an inpatient setting. Many commenters requested a permanent and long-term solution to ensure accurate payment for CAR T- cell therapy while concurrently ensuring any redistributive payment effects within the IPPS are limited. Some commenters recommended that, until a more permanent solution is developed, CMS finalize the proposed assignment of CAR T-cell therapy to MS-DRG 016, approve the NTAP application for CAR T-cell therapy, and/or allow for a CCR of 1.0 for CAR T-cell therapy. However, some commenters disagreed with CMS' proposed assignment of CAR T-cell therapy to MS-DRG 016 and requested a new separate MS-DRG. These commenters disagreed that patients receiving CAR T-cell therapy are sufficiently clinically similar to patients receiving autologous bone marrow transplants. Reasons cited by these commenters included differences in lengths of stay, the level and predictability of associated toxicity, and the overall disease burden. Some of these commenters suggested creating a new separate MS-DRG for CAR T-cell therapy and developing the FY 2019 weight for this MS-DRG not based only on historical claims data but also including alternative data on the cost of CAR T-cell therapy drugs, such as average sales price (ASP) data. Some commenters pointed to the establishment of a separate DRG for drug eluting stents under the IPPS as a possible payment model for CAR T-cell therapy. Other commenters did not support the creation of a new separate MS- DRG for CAR T-cell therapy. Reasons cited by these commenters included the relative newness of the therapy, the limited number of providers delivering these treatments, the low volume of patients, redistributive effects, and the lack of long term data surrounding length of stay, treatment complexities, and costs. These commenters urged CMS to collect more comprehensive clinical and cost data before considering assignment of a new MS-DRG to these therapies. Some commenters requested that CMS carve out the cost of CAR T-cell therapy from the IPPS and pay for it on a pass-through basis reflecting the cost of the therapy to the hospital and indicated that this was the approach taken by some state Medicaid programs. These commenters believed that payment on a pass-through basis, for inpatient and/or outpatient care, provides the most accurate payment while minimizing inappropriate payment incentives across the inpatient and outpatient setting. Commenters also made technical and operational suggestions to CMS if we were to adopt changes to our existing payment mechanisms in the final rule as they apply to CAR T-cell therapy, including how a CCR of 1.0 would be operationalized, or how CMS would collect data on the cost of CAR T-cell therapy for pass-through and other purposes. Response: Building on President Trump's Blueprint to Lower Drug Prices and Reduce Out-of-Pocket Costs, the CMS Center for Medicare and Medicaid Innovation (Innovation Center) is soliciting public comment in the CY 2019 OPPS/ASC proposed rule on key design considerations for developing a potential model that would test private market strategies and introduce competition to improve quality of care for beneficiaries, while reducing both Medicare expenditures and beneficiaries' out of pocket spending. CMS sought similar feedback in a previous solicitation of comments,\4\ and, most recently, in the President's Blueprint to Lower Drug Prices and Reduce Out-of-Pocket Costs.\5\ --------------------------------------------------------------------------- \4\ CMS included a solicitation of comments on the Competitive Acquisition Program (CAP) for Part B Drugs and Biologicals (81 FR 13247) in a proposed rule, on March 11, 2016, entitled ``Medicare Program; Part B Drug Payment Model'' (81 FR 13230). The solicitation of comments sought to help CMS determine if there was sufficient interest in the CAP program, and to gather public input if we were to consider developing and testing a future model that would be at least partly based on the authority for the CAP under section 1847B of the Act. The March 11, 2016 proposed rule was withdrawn on October 4, 2017 (82 FR 46182) to ensure agency flexibility in reexamining important issues related to the proposed payment model and exploring new options and alternatives with stakeholders as CMS develops potential payment models that support innovative approaches to improve quality, accessibility, and affordability, reduce Medicare program expenditures, and empower patients and doctors to make decisions about their health care. \5\ President Donald J. Trump's Blueprint to Lower Drug Prices and Reduce Out-of-Pocket Costs, May 11, 2018. Available at: https://www.whitehouse.gov/briefings-statements/president-donald-j-trumps-blueprint-lower-drug-prices/. --------------------------------------------------------------------------- Given the relative newness of CAR T-cell therapy, the potential model, including the reasons underlying our consideration of a potential model described in greater detail in the CY 2019 OPPS/ASC proposed rule, and our request for feedback on this model approach, we believe it would be premature to adopt changes to our existing payment mechanisms, either under the IPPS or for IPPS-excluded cancer hospitals, specifically for CAR T-cell therapy. Therefore, we disagree with commenters who have requested such changes under the IPPS for FY [[Page 41174]] 2019, including, but not limited to, the creation of a pass-through payment; structural changes in new technology add-on payments for the drug therapy; changes in the usual cost-to-charge ratios (CCRs) used in ratesetting and payment, including those used in determining new technology add-on payments, outlier payments, and payments to IPPS excluded cancer hospitals; and the creation of a new MS-DRG specifically for CAR T-cell therapy prior to gaining more experience with the therapy. We agree with commenters who recommended that we finalize the proposed assignment of CAR-T therapy to MS-DRG 016 rather than consider the creation of a new MS-DRG for these therapies, given the relative newness of the therapy, the limited number of providers delivering these treatments, the low volume of patients, redistributive effects, and the lack of long-term data surrounding length of stay, treatment complexities, and costs. In addition to the potential model, we agree we should collect more comprehensive clinical and cost data before considering assignment of a new MS-DRG to these therapies. In response to the commenters who indicated that MS-DRG 016 is a poor clinical match for CAR T-cell therapy patients and would prefer that we create a new MS-DRG for CAR-T cell therapy, we acknowledge that there are differences between the treatment approaches, but we continue to believe that MS-DRG 016 is the most appropriate match of the existing MS-DRGs, given similarities between CAR-T cell therapy and autologous bone marrow transplant in harvesting and infusion of patient cells as well as post-infusion monitoring for and management of potentially severe adverse effects. We reiterate that, in light of the potential model and our request for feedback on this approach, it would be premature to create a new MS-DRG specifically for CAR T-cell therapy. We will consider requests for alternative MS-DRG assignments and/or the creation of a new MS-DRG for CAR T-cell therapy after we review the public feedback on a potential model and as we gain further experience with CAR T-cell therapy and can better evaluate the commenters' concerns. As described in more detail in section II.H. of the preamble of this final rule, we are approving new technology add-on payments for CAR T-cell therapy for FY 2019. In response to commenters who made technical and operational suggestions if CMS were to adopt changes to its existing payment mechanisms in the final rule as they apply to CAR T-cell therapy, because we are not adopting such changes, we are not addressing those technical and operational comments at the current time but will consider them for future rulemaking as appropriate. After consideration of the public comments we received, we are finalizing our proposed approach of assigning ICD-10-PCS procedure codes XW033C3 and XW043C3 to Pre-MDC MS-DRG 016 for FY 2019 and to revise the title of MS-DRG 016 from ``Autologous Bone Marrow Transplant with CC/MCC'' to ``Autologous Bone Marrow Transplant with CC/MCC or T- cell Immunotherapy.'' 3. MDC 1 (Diseases and Disorders of the Nervous System) a. Epilepsy With Neurostimulator In the FY 2018 IPPS/LTCH PPS final rule (82 FR 38015 through 38019), based on a request we received and our review of the claims data, the advice of our clinical advisors, and consideration of public comments, we finalized our proposal to reassign all cases reporting a principal diagnosis of epilepsy and one of the following ICD-10-PCS code combinations, which capture cases involving neurostimulator generators inserted into the skull (including cases involving the use of the RNS(copyright) neurostimulator), to retitled MS-DRG 023 (Craniotomy with Major Device Implant or Acute Complex Central Nervous System (CNS) Principal Diagnosis (PDX) with MCC or Chemotherapy Implant or Epilepsy with Neurostimulator), even if there is no MCC reported: 0NH00NZ (Insertion of neurostimulator generator into skull, open approach), in combination with 00H00MZ (Insertion of neurostimulator lead into brain, open approach); 0NH00NZ (Insertion of neurostimulator generator into skull, open approach), in combination with 00H03MZ (Insertion of neurostimulator lead into brain, percutaneous approach); and 0NH00NZ (Insertion of neurostimulator generator into skull, open approach), in combination with 00H04MZ (Insertion of neurostimulator lead into brain, percutaneous endoscopic approach). The finalized listing of epilepsy diagnosis codes (82 FR 38018 through 38019) contained codes provided by the requestor (82 FR 38016), in addition to diagnosis codes organized in subcategories G40.A- and G40.B- as recommended by a commenter in response to the proposed rule (82 FR 38018) because the diagnosis codes organized in these subcategories also are representative of diagnoses of epilepsy. For FY 2019, we received a request to include two additional diagnosis codes organized in subcategory G40.1- in the listing of epilepsy diagnosis codes for cases assigned to MS-DRG 023 because these diagnosis codes also represent diagnoses of epilepsy. The two additional codes identified by the requestor are: G40.109 (Localization-related (focal) (partial) symptomatic epilepsy and epileptic syndromes with simple partial seizures, not intractable, without status epilepticus); and G40.111 (Localization-related (focal) (partial) symptomatic epilepsy and epileptic syndromes with simple partial seizures, intractable, with status epilepticus). In the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20190), we stated that we agreed with the requestor that diagnosis codes G40.109 and G40.111 also are representative of epilepsy diagnoses and should be added to the listing of epilepsy diagnosis codes for cases assigned to MS-DRG 023 because they also capture a type of epilepsy. Our clinical advisors reviewed this issue and agreed that adding the two additional epilepsy diagnosis codes is appropriate. Therefore, we proposed to add ICD-10-CM diagnosis codes G40.109 and G40.111 to the listing of epilepsy diagnosis codes for cases assigned to MS-DRG 023, effective October 1, 2018. Comment: Commenters agreed with CMS' proposal to add ICD-10-CM diagnosis codes G40.109 and G40.111 to the list of epilepsy diagnosis codes for assignment to MS-DRG 023. The commenters stated that the proposal was reasonable, given the ICD-10-CM diagnosis codes and the information provided. Response: We appreciate the commenters' support. After consideration of the public comments we received, we are finalizing our proposal to add ICD-10-CM diagnosis codes G40.109 and G40.111 to the list of epilepsy diagnosis codes for assignment to MS- DRG 023 in the ICD-10 MS-DRGs Version 36, effective October 1, 2018. b. Neurological Conditions With Mechanical Ventilation As discussed in the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20190), we received two separate, but related requests to create new MS-DRGs for cases that identify patients who have been diagnosed with neurological conditions classified under MDC 1 (Diseases and Disorders of the Nervous [[Page 41175]] System) and who require mechanical ventilation with and without a thrombolytic and in the absence of an O.R. procedure. The requestors suggested that CMS consider when mechanical ventilation is reported with a neurological condition for the ICD-10 MS-DRG GROUPER assignment logic, similar to the current logic for MS-DRGs 207 and 208 (Respiratory System Diagnosis with Ventilator Support >96 Hours and <=96 Hours, respectively) under MDC 4 (Diseases and Disorders of the Respiratory System), which consider respiratory conditions that require mechanical ventilation and are assigned a higher relative weight. The requestors stated that patients with a principal diagnosis of respiratory failure requiring mechanical ventilation are currently assigned to MS-DRG 207 (Respiratory System Diagnoses with Ventilator Support >96 Hours), which has a relative weight of 5.4845, and to MS- DRG 208 (Respiratory System Diagnoses with Ventilator Support <=96 Hours), which has a relative weight of 2.3678. The requestors also stated that patients with a principal diagnosis of ischemic cerebral infarction who received a thrombolytic agent during the hospital stay and did not undergo an O.R. procedure are assigned to MS-DRGs 061, 062, and 063 (Ischemic Stroke, Precerebral Occlusion or Transient Ischemia with Thrombolytic Agent with MCC, with CC, and without CC/MCC, respectively) under MDC 1, while patients with a principal diagnosis of intracranial hemorrhage or ischemic cerebral infarction who did not receive a thrombolytic agent during the hospital stay and did not undergo an O.R. procedure are assigned to MS-DRGs 064, 065 and 66 (Intracranial Hemorrhage or Cerebral Infarction with MCC, with CC or TPA in 24 Hours, and without CC/MCC, respectively) under MDC 1. The requestors provided the current FY 2018 relative weights for these MS-DRGs as shown in the following table. ------------------------------------------------------------------------ Relative MS-DRG MS-DRG title weight ------------------------------------------------------------------------ MS-DRG 061.................. Ischemic Stroke, 2.7979 Precerebral Occlusion or Transient Ischemia with Thrombolytic Agent with MCC. MS-DRG 062.................. Ischemic Stroke, l.9321 Precerebral Occlusion or Transient Ischemia with Thrombolytic Agent with CC. MS-DRG 063.................. Ischemic Stroke, l.6169 Precerebral Occlusion or Transient Ischemia with Thrombolytic Agent without CC/MCC. MS-DRG 064.................. Intracranial Hemorrhage or l.7685 Cerebral Infarction with MCC. MS-DRG 065.................. Intracranial Hemorrhage or 1.0311 Cerebral Infarction with CC or TPA in 24 hours. MS-DRG 066.................. Intracranial Hemorrhage or .7466 Cerebral Infarction with MCC. ------------------------------------------------------------------------ The requestors stated that although the ICD-10-CM Official Guidelines for Coding and Reporting allow sequencing of acute respiratory failure as the principal diagnosis when it is jointly responsible (with an acute neurologic event) for admission, which would result in assignment to MS-DRGs 207 or 208 when the patient requires mechanical ventilation, it would not be appropriate to sequence acute respiratory failure as the principal diagnosis when it is secondary to intracranial hemorrhage or ischemic cerebral infarction. The requestors also stated that reporting for other purposes, such as quality measures, clinical trials, and Joint Commission and State certification or survey cases, is based on the principal diagnosis, and it is important, from a quality of care perspective, that the intracranial hemorrhage or cerebral infarction codes continue to be sequenced as principal diagnosis. The requestors believed that cases of patients who present with cerebral infarction or cerebral hemorrhage and acute respiratory failure are currently in conflict for principal diagnosis sequencing because the cerebral infarction or cerebral hemorrhage code is needed as the principal diagnosis for quality reporting and other purposes. However, acute respiratory failure is needed as the principal diagnosis for purposes of appropriate payment under the MS-DRGs. The requestors stated that by creating new MS-DRGs for neurological conditions with mechanical ventilation, those patients who require mechanical ventilation for airway protection on admission and those patients who develop acute respiratory failure requiring mechanical ventilation after admission can be grouped to MS-DRGs that provide appropriate payment for the mechanical ventilation resources. The requestors suggested two new MS-DRGs, citing as support that new MS- DRGs were created for patients with sepsis requiring mechanical ventilation greater than and less than 96 hours. As discussed in the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20191) and earlier in this section, the requests we received were separate, but related requests. The first request was to specifically identify patients presenting with intracranial hemorrhage or cerebral infarction with mechanical ventilation and create two new MS-DRGs as follows: Suggested new MS-DRG XXX (Intracranial Hemorrhage or Cerebral Infarction with Mechanical Ventilation >96 Hours); and Suggested new MS-DRG XXX (Intracranial Hemorrhage or Cerebral Infarction with Mechanical Ventilation <=96 Hours). The second request was to consider any principal diagnosis under the current GROUPER logic for MDC 1 with mechanical ventilation and create two new MS-DRGs as follows: Suggested New MS-DRG XXX (Neurological System Diagnosis with Mechanical Ventilation 96+ Hours); and Suggested New MS-DRG XXX (Neurological System Diagnosis with Mechanical Ventilation <96 Hours). Both requesters suggested that CMS use the three ICD-10-PCS codes identifying mechanical ventilation to assign cases to the respective suggested new MS-DRGs. The three ICD-10-PCS codes are shown in the following table. ------------------------------------------------------------------------ ICD-10-PCS code Code description ------------------------------------------------------------------------ 5A1935Z............................. Respiratory ventilation, less than 96 consecutive hours. 5A1945Z............................. Respiratory ventilation, 24-96 consecutive hours. 5A1955Z............................. Respiratory ventilation, greater than 96 consecutive hours. ------------------------------------------------------------------------ [[Page 41176]] Below we discuss the different aspects of each request in more detail. The first request involved two aspects: (1) Analyzing patients diagnosed with cerebral infarction and required mechanical ventilation who received a thrombolytic (for example, TPA) and did not undergo an O.R. procedure; and (2) analyzing patients diagnosed with intracranial hemorrhage or ischemic cerebral infarction and required mechanical ventilation who did not receive a thrombolytic (for example, TPA) during the current episode of care and did not undergo an O.R. procedure. For the first subset of patients, we analyzed claims data from the September 2017 update of the FY 2017 MedPAR file for MS-DRGs 061, 062, and 063 because cases that are assigned to these MS-DRGs specifically identify patients who were diagnosed with a cerebral infarction and received a thrombolytic. The 90 ICD-10-CM diagnosis codes that specify a cerebral infarction and were included in our analysis are listed in Table 6P.1a associated with the proposed rule (which is available via the internet on the CMS website at: http://www.cms.hhs.gov/Medicare/Medicare-Fee-for-Service-Payment/AcuteInpatientPPS/index.html). The ICD-10-PCS procedure codes displayed in the following table describe use of a thrombolytic agent. ------------------------------------------------------------------------ ICD-10-PCS code Code description ------------------------------------------------------------------------ 3E03017............................. Introduction of other thrombolytic into peripheral vein, open approach. 3E03317............................. Introduction of other thrombolytic into peripheral vein, percutaneous approach. 3E04017............................. Introduction of other thrombolytic into central vein, open approach. 3E04317............................. Introduction of other thrombolytic into central vein, percutaneous approach. 3E05017............................. Introduction of other thrombolytic into peripheral artery, open approach. 3E05317............................. Introduction of other thrombolytic into peripheral artery, percutaneous approach. 3E06017............................. Introduction of other thrombolytic into central artery, open approach. 3E06317............................. Introduction of other thrombolytic into central artery, percutaneous approach. 3E08017............................. Introduction of other thrombolytic into heart, open approach. 3E08317............................. Introduction of other thrombolytic into heart, percutaneous approach. ------------------------------------------------------------------------ We examined claims data in MS-DRGs 061, 062, and 063 and identified cases that reported mechanical ventilation of any duration with a principal diagnosis of cerebral infarction where a thrombolytic agent was administered and the patient did not undergo an O.R. procedure. Our findings are shown in the following table.

There were a total of 758 cases reporting the use of mechanical ventilation in MS-DRG 061 with an average length of stay ranging from 4.9 days to 12.8 days and average costs ranging from $19,795 to $41,691. For MS-DRG 062, there were a total of 9,730 cases with an average length of stay of 3.9 days and average costs of $13,865. There were a total of 33 cases reporting the use of mechanical ventilation in MS-DRG 062 with an average length of stay ranging from 3.8 days to 5.3 days and average costs ranging from $14,026 to $19,817. For MS-DRG 063, there were a total of 1,984 cases with an average length of stay of 2.7 days and average costs of $11,771. There were a total of 8 cases reporting the use of mechanical ventilation in MS-DRG 063 with an average length of stay ranging from 2.0 days to 2.7 days and average costs ranging from $11,195 to $14,588. We then compared the total number of cases in MS-DRGs 061, 062, and 063 specifically reporting mechanical [[Page 41177]] ventilation >96 hours with a principal diagnosis of cerebral infarction where a thrombolytic agent was administered and the patient did not undergo an O.R. procedure against the total number of cases reporting mechanical ventilation <=96 hours with a principal diagnosis of cerebral infarction where a thrombolytic agent was administered and the patient did not undergo an O.R. procedure. Our findings are shown in the following table.

MS-DRG 063--Cases with principal diagnosis of cerebral 8 2.3 12,467 infarction and mechanical ventilation <=96 hours............... ---------------------------------------------------------------------------------------------------------------- As shown in this table, the total number of cases reported in MS- DRG 061 was 5,192, with an average length of stay of 6.4 days and average costs of $20,097. There were 166 cases that reported mechanical ventilation >96 hours, with an average length of stay of 12.8 days and average costs of $41,691. There were 594 cases that reported mechanical ventilation <=96 hours, with an average length of stay of 6.5 days and average costs of $23,780. The total number of cases reported in MS-DRG 062 was 9,730, with an average length of stay of 3.9 days and average costs of $13,865. There were no cases identified in MS-DRG 062 where mechanical ventilation >96 hours was reported. However, there were 34 cases that reported mechanical ventilation <=96 hours, with an average length of stay of 4.2 days and average costs of $15,558. The total number of cases reported in MS-DRG 63 was 1,984 with an average length of stay of 2.7 days and average costs of $11,771. There were no cases identified in MS-DRG 063 where mechanical ventilation >96 hours was reported. However, there were 8 cases that reported mechanical ventilation <=96 hours, with an average length of stay of 2.3 days and average costs of $12,467. For the second subset of patients, we examined claims data for MS- DRGs 064, 065, and 066. We identified cases reporting mechanical ventilation of any duration with a principal diagnosis of cerebral infarction or intracranial hemorrhage where a thrombolytic agent was not administered during the current hospital stay and the patient did not undergo an O.R. procedure. The 33 ICD-10-CM diagnosis codes that specify an intracranial hemorrhage and were included in our analysis are listed in Table 6P.1b associated with the proposed rule (which is available via the internet on the CMS website at: http://www.cms.hhs.gov/Medicare/Medicare-Fee-for-Service-Payment/AcuteInpatientPPS/index.html). We also used the list of 90 ICD-10-CM diagnosis codes that specify a cerebral infarction listed in Table 6P.1a associated with the proposed rule for our analysis. We noted that the GROUPER logic for case assignment to MS-DRG 065 includes that a thrombolytic agent (for example, TPA) was administered within 24 hours of the current hospital stay. The ICD-10-CM diagnosis code that describes this scenario is Z92.82 (Status post administration of tPA (rtPA) in a different facility within the last 24 hours prior to admission to current facility). We did not review the cases reporting that diagnosis code for our analysis. Our findings are shown in the following table.

The total number of cases reported in MS-DRG 66 was 34,689, with an average length of stay of 2.5 days and average costs of $5,321. There was one case that reported mechanical ventilation >96 hours, with an average length of stay of 4.0 days and average costs of $3,426, and there were 194 cases that reported mechanical ventilation <=96 hours, with an average length of stay of 1.8 days and average costs of $5,141. We also analyzed claims data for MS-DRGs 207 and 208. As shown in the following table, there were a total of 19,471 cases found in MS-DRG 207 with an average length of stay of 13.8 days and average costs of $38,124. For MS-DRG 208, there were a total of 55,802 cases found with an average length of stay of 6.7 days and average costs of $17,439.

For the first subset of patients (in MS-DRGs 061, 062 and 063), our data findings for MS-DRG 061 demonstrate the 166 cases that reported mechanical ventilation >96 hours had a longer average length of stay (12.8 days versus 6.4 days) and higher average costs ($41,691 versus $20,097) compared to all the cases in MS-DRG 061. However, there were no cases that reported mechanical ventilation >96 hours for MS-DRG 062 or MS-DRG 063. For the 594 cases that reported mechanical ventilation <=96 hours in MS-DRG 061, the data show that the average length of stay was consistent with the average length of stay of all of the cases in MS-DRG 061 (6.5 days versus 6.4 days) and the average costs were also consistent with the average costs of all of the cases in MS-DRG 061 ($23,780 versus $20,097). For the 34 cases that reported mechanical ventilation <=996 hours in MS-DRG 062, the data show that the average length of stay was consistent with the average length of stay of all of the cases in MS-DRG 062 (4.2 days versus 3.9 days) and the average costs were also consistent with the average costs of all of the cases in MS DRG 062 ($15,558 versus $13,865). Lastly, for the 8 cases that reported mechanical ventilation <=96 hours in MS-DRG 063, the data show that the average length of stay was consistent with the average length of stay of all of the cases in MS-DRG 063 (2.3 days versus 2.7 days) and the average costs were also consistent with the average costs of all of the cases in MS DRG 063 ($12,467 versus $11,771). For the second subset of patients (in MS-DRGs 064, 065 and 066), the data findings for the 2,153 cases that reported mechanical ventilation >96 hours in MS-DRG 064 showed a longer average length of stay (13.4 days versus 6.0 days) and higher average costs ($38,262 versus $12,574) compared to all of the cases in MS-DRG 064. However, the 2,153 cases represent only 2.8 percent of all the cases in MS-DRG 064. For the 22 cases that reported mechanical ventilation >96 hours in MS-DRG 065, the data showed a longer average length of stay (10.2 days versus 3.7 days) and higher average costs ($20,759 versus $7,236) compared to all of the cases in MS-DRG 065. However, the 22 cases represent only 0.02 percent of all the cases in MS-DRG 065. For the one case that reported mechanical ventilation >96 hours in MS-DRG 066, the data showed a longer average length of stay (4.0 days versus 2.5 days) and lower average costs ($3,426 versus $5,321) compared to all of the cases in MS-DRG 066. For the 8,794 cases that reported mechanical ventilation <=96 hours in MS-DRG 064, the data showed that the average length of stay was shorter than the average length of stay for all of the cases in MS-DRG 064 (4.9 days versus 6.0 days) and the average costs were consistent with the average costs of all of the cases in MS- DRG 064 ($13,704 versus $12,574). For the 428 cases that reported mechanical ventilation <=96 hours in MS-DRG 065, the data showed that the average length of stay was shorter than the average length of stay for all of the cases in MS-DRG 065 (2.7 days versus 3.7 days) and the average costs were consistent with the average costs of all the cases in MS-DRG 065 ($8,086 versus $7,236). For the 194 cases that reported mechanical ventilation <=96 hours in MS-DRG 066, the data showed that the average length of stay was shorter than the average length of stay for all of the cases in MS-DRG 066 (1.8 days versus 2.5 days) and the average costs were less than the average costs of all of the cases in MS-DRG 066 ($5,141 versus $5,321). We stated in the proposed rule that, based on the analysis described above, the current MS-DRG assignment for the cases in MS-DRGs 061, 062, 063, 064, 065 and 066 that identify patients diagnosed with cerebral infarction or intracranial hemorrhage who require mechanical ventilation with or without a thrombolytic and in the absence of an O.R. procedure appears appropriate. Our clinical advisors also noted that patients requiring mechanical ventilation (in the absence of an O.R. procedure) are known to be more resource intensive and it would not be practical to create new MS-DRGs specifically for this subset of patients diagnosed with an acute neurologic event, given the various indications for which mechanical ventilation may be utilized. We stated in the proposed rule that, if we were to create new MS-DRGs for patients diagnosed with an intracranial hemorrhage or cerebral infarction who require mechanical ventilation, it would not address all of the other patients who also utilize mechanical ventilation resources. It would also necessitate further extensive analysis and evaluation for several other conditions that require mechanical ventilation across each of the 25 MDCs under the ICD-10 MS-DRGs. To evaluate the frequency in which the use of mechanical ventilation is reported for different clinical scenarios, we examined claims data across each of the 25 MDCs to determine the number of cases reporting the use of mechanical ventilation >96 hours. Our findings are shown in the table below.

MDC 25 (Human Immunodeficiency Virus Infections)--Cases with 363 19.1 56,688 mechanical ventilation >96 hours............................... ---------------------------------------------------------------------------------------------------------------- As shown in the table, the top 5 MDCs with the largest number of cases reporting mechanical ventilation >96 hours are MDC 18, with 48,176 cases; MDC 4, with 27,793 cases; MDC 5, with 16,923 cases; MDC 1, with 13,668 cases; and MDC 6, with 6,401 cases. We noted that the claims data demonstrate that the average length of stay is consistent with what we would expect for cases reporting the use of mechanical ventilation >96 hours across each of the 25 MDCs. The top 5 MDCs with the highest average costs for cases reporting mechanical ventilation >96 hours were MDC 22, with average costs of $188,704; MDC 17, with average costs of $99,968; MDC 12, with average costs of $95,204; MDC 5, with average costs of $84,565; and MDC 13, with average costs of $83,319. We noted that the data for MDC 8 demonstrated similar results compared to MDC 13 with average costs of $83,271 for cases reporting mechanical ventilation >96 hours. In summary, the claims data reflect a wide variance with regard to the frequency and average costs for cases reporting the use of mechanical ventilation >96 hours. We also examined claims data across each of the 25 MDCs for the number of cases reporting the use of mechanical ventilation <=96 hours. Our findings are shown in the table below.

MDC 25 (Human Immunodeficiency Virus Infections)--Cases with 541 10.4 29,255 mechanical ventilation <=96 hours.............................. ---------------------------------------------------------------------------------------------------------------- As shown in the table, the top 5 MDCs with the largest number of cases reporting mechanical ventilation <=96 hours are MDC 18, with 69,826 cases; MDC 4, with 64,861 cases; MDC 5, with 45,147 cases; MDC 1, with 29,896 cases; and MDC 6, with 15,629 cases. We noted that the claims data demonstrate that the average length of stay is consistent with what we would expect for cases reporting the use of mechanical ventilation <=96 hours across each of the 25 MDCs. The top 5 MDCs with the highest average costs for cases reporting mechanical ventilation <=96 hours are MDC 17, with average costs of $46,335; MDC 22, with average costs of $45,557; MDC 8, with average costs of $40,183; MDC 24, with average costs of $36,475; and MDC 5, with average costs of $35,818. Similar to the cases reporting mechanical ventilation >96 hours, the claims data for cases reporting the use of mechanical ventilation <=96 hours also reflect a wide variance with regard to the frequency and average costs. Depending on the number of cases in each MS-DRG, it may be difficult to detect patterns of complexity and resource intensity. With respect to the requestor's statement that reporting for other purposes, such as quality measures, clinical trials, and Joint Commission and State certification or survey cases, is based on the principal diagnosis, and their belief that patients who present with cerebral infarction or cerebral hemorrhage and acute respiratory failure are currently in conflict for principal diagnosis sequencing because the cerebral infarction or cerebral hemorrhage code is needed as the principal diagnosis for quality reporting and other purposes (however, acute respiratory failure is needed as the principal diagnosis for purposes of appropriate payment under the MS-DRGs), we noted that providers are required to assign the principal diagnosis according to the ICD-10-CM Official Guidelines for Coding and Reporting and these assignments are not based on factors such as quality measures or clinical trials indications. Furthermore, we do not base MS-DRG reclassification decisions on those factors. If the cerebral hemorrhage or ischemic cerebral infarction is the reason for admission to the hospital, the cerebral hemorrhage or ischemic cerebral infarction diagnosis code should be assigned as the principal diagnosis. We acknowledged in the proposed rule that new MS-DRGs were created for cases of patients with sepsis requiring mechanical ventilation greater than and less than 96 hours. However, those MS-DRGs (MS-DRG 575 (Septicemia with Mechanical Ventilation 96+ Hours Age >17) and MS-DRG 576 (Septicemia without Mechanical Ventilation 96+ Hours Age >17)) were created several years ago, in FY 2007 (71 FR 47938 through 47939) in response to public comments suggesting alternatives for the need to recognize the treatment for that subset of patients with severe sepsis who exhibit a greater degree of severity and resource consumption as septicemia is a systemic condition, and also as a [[Page 41182]] preliminary step in the transition from the CMS DRGs to MS-DRGs. We stated in the proposed rule that we believe that additional analysis and efforts toward a broader approach to refining the MS-DRGs for cases of patients requiring mechanical ventilation across the MDCs involves carefully examining the potential for instability in the relative weights and disrupting the integrity of the MS-DRG system based on the creation of separate MS-DRGs involving small numbers of cases for various indications in which mechanical ventilation may be required. The second request focused on patients diagnosed with any neurological condition classified under MDC 1 requiring mechanical ventilation in the absence of an O.R. procedure and without having received a thrombolytic agent. Because the first request specifically involved analysis for the acute neurological conditions of cerebral infarction and intracranial hemorrhage under MDC 1 and our findings did not support creating new MS-DRGs for those specific conditions, we did not perform separate claims analysis for other conditions classified under MDC 1. Therefore, in the FY 2019 IPPS/LTCH PPS proposed rule, we did not propose to create new MS-DRGs for cases that identify patients diagnosed with neurological conditions classified under MDC 1 who require mechanical ventilation with or without a thrombolytic and in the absence of an O.R. procedure. Comment: Commenters supported CMS' proposal to not create new MS- DRGs, classified under MDC 1, for cases representing patients diagnosed with a neurological condition who require mechanical ventilation with or without a thrombolytic, and in the absence of an O.R. procedure. The commenters stated that the proposal was reasonable, given the data, the ICD-10-CM diagnosis codes, the ICD-10-PCS procedure codes, and the information provided. However, the commenters also recommended that CMS continue to conduct further analyses across all the MDCs for the subset of patients who require mechanical ventilation in an effort to better address the reporting and payment issues. Response: We appreciate the commenters' support and agree that further analyses are necessary to evaluate the development of potential proposals for the subset of patients requiring mechanical ventilation across all the MDCs. Comment: One commenter disagreed with CMS' proposal to not create new MS-DRGs for patients admitted with strokes and treated with mechanical ventilation. The commenter expressed appreciation for CMS' efforts in analyzing the cost and length of stay data for this subset of patients. However, the commenter believed that the results of the analysis identifying patients who receive mechanical ventilation >96 hours and also have an MCC demonstrate that these cases require twice the cost of all cases in MS-DRG 61 (Ischemic Stroke, Precerebral Occlusion or Transient Ischemia with Thrombolytic Agent with MCC) and MS-DRG 64 (Intracranial Hemorrhage or Cerebral Infarction with MCC). The commenter requested that CMS reconsider alternative options for this subset of patients due to the cost and length of stay disparities. Response: We acknowledge the commenters' concern that the average length of stay and average costs for cases where mechanical ventilation >96 hours was reported with an MCC for MS-DRG 61 and MS-DRG 64 are greater when compared to the average length of stay and average costs for all cases in those MS-DRGs. However, as stated in the FY 2019 IPPS/ LTCH PPS proposed rule (83 FR 20195), our clinical advisors noted that patients requiring mechanical ventilation are known to be more resource intensive and it would not be practical to create new MS-DRGs for this subset of patients given the various other indications in which mechanical ventilation may be utilized for other patients. We will consider additional analysis in the future in our efforts toward a broader approach to refining the MS-DRGs for cases of patients requiring mechanical ventilation across the MDCs. Comment: One commenter suggested that, although CMS' analysis of the cases reporting a neurological condition with mechanical ventilation was acceptable, CMS consider creating a new MS-DRG for poisoning with mechanical ventilation in future rulemaking. The commenter believed that a patient who is in critical condition as a result of a poisoning and requires prolonged mechanical ventilation is not being recognized appropriately under the current MS-DRG relative payment weights. Response: We appreciate the commenter's input and suggestion. As noted earlier, we will consider additional analysis in our efforts toward a broader approach to refining the MS-DRGs for cases of patients requiring mechanical ventilation across the MDCs. After consideration of the public comments we received, we are finalizing our proposal to not create new MS-DRGs, classified under MDC 1, for cases that identify patients requiring mechanical ventilation and are diagnosed with stroke or any other neurological condition with or without a thrombolytic, and in the absence of an O.R. procedure for FY 2019. 4. MDC 5 (Diseases and Disorders of the Circulatory System) a. Pacemaker Insertions In the FY 2017 IPPS/LTCH PPS final rule (81 FR 56804 through 56809), we discussed a request to examine the ICD-10-PCS procedure code combinations that describe procedures involving pacemaker insertions to determine if some procedure code combinations were excluded from the Version 33 ICD-10 MS-DRG assignments for MS-DRGs 242, 243, and 244 (Permanent Cardiac Pacemaker Implant with MCC, with CC, and without CC/ MCC, respectively) under MDC 5. We finalized our proposal to modify the Version 34 ICD-10 MS-DRG GROUPER logic so the specified procedure code combinations were no longer required for assignment into those MS-DRGs. As a result, the logic for pacemaker insertion procedures was simplified by separating the procedure codes describing cardiac pacemaker device insertions into one list and separating the procedure codes describing cardiac pacemaker lead insertions into another list. Therefore, when any ICD-10-PCS procedure code describing the insertion of a pacemaker device is reported from that specific logic list with any ICD-10-PCS procedure code describing the insertion of a pacemaker lead from that specific logic list (81 FR 56804 through 56806), the case is assigned to MS-DRGs 242, 243, and 244 under MDC 5. We then discussed our examination of the Version 33 GROUPER logic for MS-DRGs 258 and 259 (Cardiac Pacemaker Device Replacement with and without MCC, respectively) because assignment of cases to these MS-DRGs also included qualifying ICD-10-PCS procedure code combinations involving pacemaker insertions (81 FR 56806 through 56808). Specifically, the logic for Version 33 ICD-10 MS-DRGs 258 and 259 included ICD-10-PCS procedure code combinations describing the removal of pacemaker devices and the insertion of new pacemaker devices. We finalized our proposal to modify the Version 34 ICD-10 MS-DRG GROUPER logic for MS-DRGs 258 and 259 to establish that a case reporting any procedure code from the list of ICD-10-PCS procedure codes describing procedures involving pacemaker device insertions without any other procedure [[Page 41183]] codes describing procedures involving pacemaker leads reported would be assigned to MS-DRGs 258 and 259 (81 FR 56806 through 56807) under MDC 5. In addition, we pointed out that a limited number of ICD-10-PCS procedure codes describing pacemaker insertion are classified as non- operating room (non-O.R.) codes within the MS-DRGs and that the Version 34 ICD-10 MS-DRG GROUPER logic would continue to classify these procedure codes as non-O.R. codes. We noted that a case reporting any one of these non-O.R. procedure codes describing a pacemaker device insertion without any other procedure code involving a pacemaker lead would be assigned to MS-DRGs 258 and 259. Therefore, the listed procedure codes describing a pacemaker device insertion under MS-DRGs 258 and 259 are designated as non-O.R. affecting the MS-DRG. Lastly, we discussed our examination of the Version 33 GROUPER logic for MS-DRGs 260, 261, and 262 (Cardiac Pacemaker Revision Except Device Replacement with MCC, with CC, and without CC/MCC, respectively), and noted that cases assigned to these MS-DRGs also included lists of procedure code combinations describing procedures involving the removal of pacemaker leads and the insertion of new leads, in addition to lists of single procedure codes describing procedures involving the insertion of pacemaker leads, removal of cardiac devices, and revision of cardiac devices (81 FR 56808). We finalized our proposal to modify the ICD-10 MS-DRG GROUPER logic for MS-DRGs 260, 261, and 262 so that cases reporting any one of the listed ICD-10-PCS procedure codes describing procedures involving pacemakers and related procedures and associated devices are assigned to MS DRGs 260, 261, and 262 under MDC 5. Therefore, the GROUPER logic that required a combination of procedure codes be reported for assignment into MS-DRGs 260, 261 and 262 under Version 33 was no longer required effective with discharges occurring on or after October 1, 2016 (FY 2017) under Version 34 of the ICD-10 MS-DRGs. In the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20198), we noted that while the discussion in the FY 2017 IPPS/LTCH PPS final rule focused on the MS-DRGs involving pacemaker procedures under MDC 5, similar GROUPER logic exists in Version 33 of the ICD-10 MS-DRGs under MDC 1 (Diseases and Disorders of the Nervous System) in MS-DRGs 040, 041 and 042 (Peripheral, Cranial Nerve and Other Nervous System Procedures with MCC, with CC or Peripheral Neurostimulator and without CC/MCC, respectively) and MDC 21 (Injuries, Poisonings and Toxic Effects of Drugs) in MS-DRGs 907, 908, and 909 (Other O.R. Procedures for Injuries with MCC, with CC, and without MCC, respectively) where procedure code combinations involving cardiac pacemaker device insertions or removals and cardiac pacemaker lead insertions or removals are required to be reported together for assignment into those MS-DRGs. We also noted that, with the exception of when a principal diagnosis is reported from MDC 1, MDC 5, or MDC 21, the procedure codes describing the insertion, removal, replacement, or revision of pacemaker devices are assigned to a medical MS-DRG in the absence of another O.R. procedure according to the GROUPER logic. We referred the reader to the ICD-10 MS-DRG Definitions Manual Version 33, which is available via the internet on the CMS website at: https://www.cms.gov/Medicare/Medicare-Fee-for-Service-Payment/AcuteInpatientPPS/FY2016-IPPS-Final-Rule-Home-Page-Items/FY2016-IPPS-Final-Rule-Data-Files.html?DLPage=1&DLEntries=10&DLSort=0&DLSortDir=ascending for complete documentation of the GROUPER logic that was in effect at that time for the Version 33 ICD-10 MS-DRGs discussed earlier. As discussed in the FY 2019 IPS/LTCH PPS proposed rule (83 FR 20198), for FY 2019, we received a request to assign all procedures involving the insertion of pacemaker devices to surgical MS-DRGs, regardless of the principal diagnosis. The requestor recommended that procedures involving pacemaker insertion be grouped to surgical MS-DRGs within the MDC to which the principal diagnosis is assigned, or that they group to MS-DRGs 981, 982, and 983 (Extensive O.R. Procedure Unrelated to Principal Diagnosis with MCC, with CC and without CC/MCC, respectively). Currently, in Version 35 of the ICD-10 MS-DRGs, procedures involving pacemakers are assigned to MS-DRGs 040, 041, and 042 (Peripheral, Cranial Nerve and Other Nervous System Procedures with MCC, with CC or Peripheral Neurostimulator and without CC/MCC, respectively) under MDC 1 (Diseases and Disorders of the Nervous System), to MS-DRGs 242, 243, and 244 (Permanent Cardiac Pacemaker Implant with MCC, with CC, and without CC/MCC, respectively), MS-DRGs 258 and 259 (Cardiac Pacemaker Device Replacement with MCC and without MCC, respectively), and MS-DRGs 260, 261 and 262 (Cardiac Pacemaker Revision Except Device Replacement with MCC, with CC, and without CC/ MCC, respectively) under MDC 5 (Diseases and Disorders of the Circulatory System), and to MS-DRGs 907, 908, and 909 (Other O.R. Procedures for Injuries with MCC, with CC, and without CC/MCC, respectively), under MDC 21 (Injuries, Poisoning and Toxic Effects of Drugs), with all other unrelated principal diagnoses resulting in a medical MS-DRG assignment. According to the requestor, the medical MS- DRGs do not provide adequate payment for the pacemaker device, specialized operating suites, time, skills, and other resources involved for pacemaker insertion procedures. Therefore, the requestor recommended that procedures involving pacemaker insertions be grouped to surgical MS-DRGs. We refer readers to the ICD-10 MS-DRG Definitions Manual Version 35, which is available via the internet on the CMS website at: https://www.cms.gov/Medicare/Medicare-Fee-for-Service-Payment/AcuteInpatientPPS/FY2018-IPPS-Final-Rule-Home-Page-Items/FY2018-IPPS-Final-Rule-Data-Files.html?DLPage=1&DLEntries=10&DLSort=0&DLSortDir=ascending for complete documentation of the GROUPER logic for the MS-DRGs discussed earlier. The following procedure codes describe procedures involving the insertion of a cardiac rhythm related device which are classified as a type of pacemaker insertion under the ICD-10 MS-DRGs. These four codes are assigned to MS-DRGs 040, 041, and 042, as well as MS-DRGs 907, 908, and 909, and are designated as O.R. procedures. ------------------------------------------------------------------------ ICD-10-PCS code Code description ------------------------------------------------------------------------ 0JH60PZ...................

The figure represents the frequency in which the number of pacemaker insertion procedures was reported. We found a total of 58,765 cases in MS-DRGs 242, 243, and 244 with an average length of stay of 4.6 days and average costs of $20,253. We found a total of 58,822 cases reporting pacemaker insertion procedures in MS-DRGs 242, 243, and 244 with an average length of stay of 4.6 days and average costs of $20,270. We note that the analysis performed is by procedure code, and because multiple pacemaker insertion procedures may be reported on a single claim, the total number of these pacemaker insertion procedure cases exceeds the total number of all cases found across MS-DRGs 242, 243, and 244 (58,822 procedures versus 58,765 cases). We then analyzed claims for cases reporting a procedure code describing (1) the insertion of a pacemaker device only, (2) the insertion of a pacemaker lead only, and (3) both the insertion of a pacemaker device and a pacemaker lead across all the MDCs except MDC 5 to determine the number of cases currently grouping to medical MS-DRGs and the potential impact of these cases moving into the surgical unrelated MS-DRGs 981, 982 and 983 (Extensive O.R. Procedure Unrelated to Principal Diagnosis with MCC, with CC and without CC/MCC, respectively). Our findings are shown in the following table. Pacemaker Insertion Procedures in Medical MS-DRGs ---------------------------------------------------------------------------------------------------------------- Number of Average length All MDCs except MDC 5 cases of stay Average costs ---------------------------------------------------------------------------------------------------------------- Procedures for insertion of pacemaker device.................... 2,747 9.5 $29,389 Procedures for insertion of pacemaker lead...................... 2,831 9.4 29,240 Procedures for insertion of pacemaker device with insertion of 2,709 9.4 29,297 pacemaker lead................................................. ---------------------------------------------------------------------------------------------------------------- We found a total of 2,747 cases reporting the insertion of a pacemaker device in 177 medical MS-DRGs with an average length of stay of 9.5 days and average costs of $29,389 across all the MDCs except MDC 5. We found a total of 2,831 cases reporting the insertion of a pacemaker lead in 175 medical MS-DRGs with an average length of stay of 9.4 days and average costs of $29,240 across all the MDCs except MDC 5. We found a total of 2,709 cases reporting both the insertion of a pacemaker device and the insertion of a pacemaker lead in 170 medical MS-DRGs with an average length of stay of 9.4 days and average costs of $29,297 across all the MDCs except MDC 5. We also analyzed claims for cases reporting a procedure code describing the insertion of a pacemaker device with a procedure code describing the insertion of a pacemaker lead in all the surgical MS- DRGs across all the MDCs except MDC 5. Our findings are shown in the following table. [[Page 41188]] Pacemaker Insertion Procedures in Surgical MS-DRGs ---------------------------------------------------------------------------------------------------------------- Average length All MDCs except MDC 5 Number of cases of stay Average costs ---------------------------------------------------------------------------------------------------------------- Procedures for insertion of pacemaker device with insertion 3,667 12.8 $48,856 of pacemaker lead........................................... ---------------------------------------------------------------------------------------------------------------- We found a total of 3,667 cases reporting the insertion of a pacemaker device and the insertion of a pacemaker lead in 194 surgical MS-DRGs with an average length of stay of 12.8 days and average costs of $48,856 across all the MDCs except MDC 5. For cases where the insertion of a pacemaker device, the insertion of a pacemaker lead or the insertion of both a pacemaker device and lead were reported on a claim grouping to a medical MS-DRG, the average length of stay and average costs were generally higher for these cases when compared to the average length of stay and average costs for all the cases in their assigned MS-DRGs. For example, we found 113 cases reporting both the insertion of a pacemaker device and lead in MS-DRG 378 (G.I. Hemorrhage with CC), with an average length of stay of 7.1 days and average costs of $23,711. The average length of stay for all cases in MS-DRG 378 was 3.6 days and the average cost for all cases in MS-DRG 378 was $7,190. The average length of stay for cases reporting both the insertion of a pacemaker device and lead were twice as long as the average length of stay for all the cases in MS-DRG 378 (7.1 days versus 3.6 days). In addition, the average costs for the cases reporting both the insertion of a pacemaker device and lead were approximately $16,500 higher than the average costs of all the cases in MS-DRG 378 ($23,711 versus $7,190). We refer readers to Table 6P.1c associated with the proposed rule (which is available via the internet on the CMS website) for the detailed report of our findings across the other medical MS-DRGs. We note that the average costs and average length of stay for cases reporting the insertion of a pacemaker device, the insertion of a pacemaker lead or the insertion of both a pacemaker device and lead are reflected in Columns D and E, while the average costs and average length of stay for all cases in the respective MS-DRG are reflected in Columns I and J. The claims data results from our analysis of this request showed that if we were to support restructuring the GROUPER logic so that pacemaker insertion procedures that include a combination of the insertion of the pacemaker device with the insertion of the pacemaker lead are designated as an O.R. procedure across all the MDCs, we would expect approximately 2,709 cases to move or ``shift'' from the medical MS-DRGs where they are currently grouping into the surgical unrelated MS-DRGs 981, 982, and 983. Our clinical advisors reviewed the data results and recommended that pacemaker insertion procedures involving a complete pacemaker system (insertion of pacemaker device combined with insertion of pacemaker lead) warrant classification into surgical MS-DRGs because the patients receiving these devices demonstrate greater treatment difficulty and utilization of resources when compared to procedures that involve the insertion of only the pacemaker device or the insertion of only the pacemaker lead. We note that the request we addressed in the FY 2017 IPPS/LTCH PPS proposed rule (81 FR 24981 through 24984) was to determine if some procedure code combinations were excluded from the ICD-10 MS-DRG assignments for MS-DRGs 242, 243, and 244. We proposed and, upon considering public comments received, finalized an alternate approach that we believed to be less complicated. We also stated in the FY 2017 IPPS/LTCH PPS final rule (81 FR 56806) that we would continue to monitor the MS-DRGs for pacemaker insertion procedures as we receive ICD-10 claims data. Upon further review, we stated that we believe that recreating the procedure code combinations for pacemaker insertion procedures would allow for the grouping of these procedures to the surgical MS-DRGs, which we believe is warranted to better recognize the resources and complexity of performing these procedures. Therefore, in the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20203), we proposed to recreate pairs of procedure code combinations involving both the insertion of a pacemaker device with the insertion of a pacemaker lead to act as procedure code combination pairs or ``clusters'' in the GROUPER logic that are designated as O.R. procedures outside of MDC 5 when reported together. Comment: Commenters supported the proposal to recreate pairs of procedure code combinations involving both the insertion of a pacemaker device with the insertion of a pacemaker lead to act as procedure code combination pairs or ``clusters'' in the GROUPER logic that are designated as O.R. procedures outside of MDC 5 when reported together. One commenter specifically expressed its appreciation of CMS' efforts to update the MS-DRG GROUPER logic to better recognize the resources and complexity of pacemaker device and lead procedures. Another commenter disagreed with the proposal to use pacemaker code pairs for assignment to a surgical MS-DRG, stating it would be more appropriate to designate each pacemaker device and pacemaker lead procedure code as an O.R. procedure to allow initial insertions and replacement of individual components to group to surgical MS-DRGs within all MDCs. According to the commenter, this designation would compensate providers for the cost of the device and the resources utilized in the performance of initial insertions and the replacement of individual components. Response: We appreciate the commenters' support. With regard to the commenter who disagreed with the proposal to utilize pacemaker code pairs for assignment to a surgical MS-DRG and suggested that the GROUPER logic designate each pacemaker device and pacemaker lead procedure code as an O.R. procedure to allow initial insertions and replacement of individual components to group to surgical MS-DRGs within all MDCs, we note that, as displayed in Table 6P.1c. associated with the FY 2019 IPPS/LTCH PPS proposed rule (which is available via the internet on the CMS website), our claims analysis for cases reporting a procedure code describing the insertion of a pacemaker device only demonstrated a total of six cases across all the medical MS-DRGs, and for cases reporting a procedure code describing the insertion of a pacemaker lead only, the data demonstrated a total of four cases across all the medical MS-DRGs. As a result, there were a total of only 10 cases where a stand-alone code for insertion of a pacemaker device procedure or a stand-alone code for insertion of a pacemaker lead procedure was reported. Those 10 cases grouped to 10 different medical MS-DRGs, of which 8 included a CC or MCC diagnosis. Therefore, it is not clear how much of the average costs, the average length of stay, the complexity of service, and resource utilization for those cases [[Page 41189]] are attributable to the insertion of the pacemaker device/lead procedure versus the severity of illness. After consideration of the public comments we received, we are finalizing our proposal to recreate pairs of procedure code combinations involving both the insertion of a pacemaker device with the insertion of a pacemaker lead to act as procedure code combination pairs or ``clusters'' in the GROUPER logic that are designated as O.R. procedures outside of MDC 5 when reported together under the ICD-10 MS- DRGs Version 36, effective October 1, 2018. We also proposed to designate all the procedure codes describing the insertion of a pacemaker device or the insertion of a pacemaker lead as non-O.R. procedures when reported as a single, individual stand-alone code based on the recommendation of our clinical advisors as noted in the proposed rule and earlier in this section and consistent with how these procedures were classified under the Version 33 ICD-10 MS-DRG GROUPER logic. Comment: A number of commenters supported the proposal to designate all the procedure codes describing the insertion of a pacemaker device or the insertion of a pacemaker lead as non-O.R. procedures when reported as a single, individual stand-alone code. However, other commenters opposed the proposal. One commenter acknowledged that the complexity of inserting a full pacemaker system is greater than when inserting a pacemaker lead or generator. However, this commenter asserted that the complexity does not increase significantly and that the placement of a lead or generator still requires the use of an operating room, sterile field, anesthesiology, and preparing the patient. The commenter believed that the placement of a pacemaker lead or device does require the use of an operating room and expressed concern that CMS would designate the procedures as a non-O.R. procedure. Response: We appreciate the commenters' support. With regard to the commenter who expressed concern that we proposed to designate procedure codes describing the insertion of a pacemaker device or the insertion of a pacemaker lead as non-O.R. procedures when reported as a single, individual stand-alone code, we note that historically, these procedures have been designated as non-O.R. procedures. As we noted in the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20203), our proposal to designate all the procedure codes describing the insertion of a pacemaker device or the insertion of a pacemaker lead as non-O.R. procedures when reported as a single, individual stand-alone code is consistent with how these procedures were classified under the Version 33 ICD-10 MS-DRG GROUPER logic. In addition, our clinical advisors continue to support the non-O.R. designation because, as the commenter noted in its own comments, while these procedures may require a sterile field, anesthesia and preparing the patient, the complexity of inserting a pacemaker lead or generator alone is less than that of inserting a full pacemaker system and the former can be performed in settings such as cardiac catheterization laboratories. After consideration of the public comments we received, we are finalizing our proposal to designate all the procedure codes describing the insertion of a pacemaker device or the insertion of a pacemaker lead as non-O.R. procedures when reported as a single, individual stand-alone code outside of MDC 5 under the ICD-10 MS-DRGs Version 36, effective October 1, 2018. In the proposed rule, we referred readers to Table 6P.1d, Table 6P.1e, and Table 6P.1f. associated with the proposed rule (which is available via the internet on the CMS website at: http://www.cms.hhs.gov/Medicare/Medicare-Fee-for-Service-Payment/AcuteInpatientPPS/index.html) for (1) a complete list of the proposed procedure code combinations or ``pairs''; (2) a complete list of the procedure codes describing the insertion of a pacemaker device; and (3) a complete list of the procedure codes describing the insertion of a pacemaker lead. We invited public comments on our lists of procedure codes that we proposed to include for restructuring the ICD-10 MS-DRG GROUPER logic for pacemaker insertion procedures. In addition, we proposed to maintain the current GROUPER logic for MS-DRGs 258 and 259 (Cardiac Pacemaker Device Replacement with MCC and without MCC, respectively) where the listed procedure codes as shown in the ICD-10 MS-DRG Definitions Manual Version 35, which is available via the internet on the CMS website at: https://www.cms.gov/Medicare/Medicare-Fee-for-Service-Payment/AcuteInpatientPPS/FY2018-IPPS-Final-Rule-Home-Page-Items/FY2018-IPPS-Final-Rule-Data-Files.html?DLPage=1&DLEntries=10&DLSort=0&DLSortDir=ascending, describing a pacemaker device insertion, continue to be designated as ``non-O.R. affecting the MS-DRG'' because they are reported when a pacemaker device requires replacement and have a corresponding diagnosis from MDC 5. Also, we proposed to maintain the current GROUPER logic for MS-DRGs 260, 261, and 262 (Cardiac Pacemaker Revision Except Device Replacement with MCC, with CC, and without CC/MCC, respectively) so that cases reporting any one of the listed ICD-10-PCS procedure codes as shown in the ICD-10 MS-DRG Definitions Manual Version 35 describing procedures involving pacemakers and related procedures and associated devices will continue to be assigned to those MS DRGs under MDC 5 because they are reported when a pacemaker device requires revision and they have a corresponding circulatory system diagnosis. Comment: Commenters agreed with the proposed lists of procedure codes for restructuring the ICD-10 MS DRG GROUPER logic for pacemaker insertion procedures. One commenter also suggested the addition of ICD- 10-PCS procedure code 02H63MZ (Insertion of cardiac lead into right atrium, percutaneous approach) and ICD-10-PCS procedure code 02H73MZ (Insertion of cardiac lead into left atrium, percutaneous approach) to Tables 6P.1d. and Table 6P.1f. that were associated with the proposed rule. The commenter noted that the tables included the open and percutaneous endoscopic approaches but did not include the percutaneous approach. Response: We appreciate the commenters' support. We agree with the commenter to add ICD-10-PCS procedure codes 02H63MZ and 02H73MZ to Table 6P.1d and as reflected in Table 6P.1f. associated with this final rule (which is available via the internet on the CMS website), to be included for the pacemaker insertion code pairs and as stand-alone codes for the insertion of a pacemaker lead. The codes are consistent with the other insertion of cardiac lead procedures and were inadvertently omitted from the initial list. After consideration of the public comments we received, we are finalizing the lists of the procedure codes in Tables 6P.1d., Table 6P.1e., and Table 6P.1f associated with the proposed rule, with the addition of ICD-10-PCS procedure codes 02H63MZ and 02H73MZ to be included for the pacemaker insertion code pairs and as stand-alone codes for the insertion of a pacemaker lead, as reflected in Tables 6P.1.d. and 6P.1.f. associated with this final rule. We also are finalizing our proposal to maintain the current GROUPER logic for MS- DRGs 258 and 259 and for MS-DRGs 260, 261, and 262 [[Page 41190]] under the ICD-10 Version 36, effective October 1, 2018. We noted in the proposed rule that, while the requestor did not include the following procedure codes in its request, these codes are also currently designated as O.R. procedure codes and are assigned to MS-DRGs 260, 261, and 262 under MDC 5. ------------------------------------------------------------------------ ICD-10-PCS code Code description ------------------------------------------------------------------------ 02PA0MZ.............................

Revision of cardiac rhythm related device in trunk subcutaneous tissue and fascia, open approach. 0JWT3PZ............................. Revision of cardiac rhythm related device in trunk subcutaneous tissue and fascia, percutaneous approach. ------------------------------------------------------------------------ In the proposed rule, we solicited public comments on whether these procedure codes describing the removal or revision of a cardiac lead and removal or revision of a cardiac rhythm related (pacemaker) device should also be designated as non-O.R. procedure codes for FY 2019 when reported as a single, individual stand-alone code with a principal diagnosis outside of MDC 5 for consistency in the classification among these devices. Comment: One commenter recommended that CMS not finalize the proposed designation of the procedure codes listed in the above table describing the removal or revisions of a cardiac lead and the removal or revision of a cardiac rhythm related (pacemaker) device from O.R. procedures to non-O.R. procedures when reported as a single, individual stand-alone code when reported with a principal diagnosis outside of MDC 5. Another commenter expressed concern that the rationale for the proposal was not clear and warranted additional clarification about the data used to arrive at this recommendation. According to this commenter, regardless of the principal diagnosis, the resources for procedures involving insertion, removal or revision of a pacemaker generator or lead are the same. The commenter further noted that revisions are often more complex and require greater resources. The commenter recommended that CMS continue to designate the procedures as O.R. procedures and further explain the proposal. Response: We appreciate the commenter's feedback. We note that while we were soliciting comments on the procedure codes listed in the table above that describe the removal or revision of a cardiac lead and the removal or revision of a cardiac rhythm related (pacemaker) device, we did not specifically recommend a change to the designation of the procedure codes at this time. We agree with the commenter that the removal or revision of a cardiac lead or pacemaker generator can be more complex and require greater resources than an initial insertion procedure. After consideration of the public comments we received, we are maintaining the O.R. designation of the procedure codes listed in the above table under the ICD-10 MS-DRGs Version 36, effective October 1, 2018. As additional claims data become available, we will continue to analyze these procedures. We also note in the proposed rule that, while the requestor did not include the following procedure codes in its request, the codes in the following table became effective October 1, 2016 (FY 2017) and also describe procedures involving the insertion of a pacemaker. Specifically, the following list includes procedure codes that describe an intracardiac or ``leadless'' pacemaker. These procedure codes are designated as O.R. procedure codes and are currently assigned to MS- DRGs 228 and 229 (Other Cardiothoracic Procedures with MCC and without MCC, respectively) under MDC 5. ------------------------------------------------------------------------ ICD-10-PCS code Code description ------------------------------------------------------------------------ 02H40NZ...................

Insertion of intracardiac pacemaker into coronary vein, percutaneous approach. ------------------------------------------------------------------------ We examined claims data for procedures involving an intracardiac pacemaker reporting any of the above codes across all MS-DRGs. Our findings are shown in the following table. Intracardiac Pacemaker Procedures ---------------------------------------------------------------------------------------------------------------- Average length Across all MS-DRGs Number of cases of stay Average costs ---------------------------------------------------------------------------------------------------------------- Procedures for intracardiac pacemaker........................ 1,190 8.6 $38,576 ---------------------------------------------------------------------------------------------------------------- We found 1,190 cases reporting a procedure involving an intracardiac pacemaker with an average length of stay of 8.6 days and average costs of $38,576. Of these 1,190 cases, we found 1,037 cases in MS-DRGs under MDC 5. We also found that the 153 cases that grouped to MS-DRGs outside of MDC 5 grouped to surgical MS-DRGs; therefore, another O.R. procedure was also reported on the claim. However, in the FY 2019 IPPS/LTCH PPS proposed rule, we solicited public comments on whether these procedure codes describing the insertion and revision of intracardiac pacemakers should also be considered for classification into all surgical unrelated MS-DRGs outside of MDC 5 for FY 2019. Comment: Commenters supported classifying the procedure codes listed in the table above describing the insertion and revision of intracardiac pacemakers into all surgical unrelated MS-DRGs outside of MDC 5. Response: We appreciate the commenters' feedback. We note that while we solicited comments on the procedure codes listed in the table above that describe the insertion of an intracardiac pacemaker device, we did not specifically recommend a change to the designation of the procedure codes at this time. We also note that, currently, the procedures are already classified within the GROUPER logic as extensive O.R. procedures. Therefore, if one of the procedure codes is reported with a principal diagnosis outside of MDC 5, the case will group to one of the unrelated surgical MS-DRGs. After consideration of the public comments we received, we are maintaining the O.R. designation of the procedure codes listed in the above table under the ICD-10 MS-DRGs Version 36, effective October 1, 2018. As additional claims data become available, we will continue to analyze these procedures. b. Drug-Coated Balloons in Endovascular Procedures In the FY 2018 IPPS/LTCH PPS final rule (82 FR 38111), we discontinued new technology add-on payments for the LUTONIX[supreg] and IN.PACTTM AdmiralTM drug-coated balloon (DCB) technologies, effective for FY 2018, because the technology no longer met the newness criterion for new technology add-on payments. For FY 2019, we received a request to reassign cases that utilize a drug- coated balloon in the performance of an endovascular procedure involving the treatment of superficial femoral arteries for peripheral arterial disease from the lower severity level MS-DRG 254 (Other Vascular Procedures without CC/MCC) and MS-DRG 253 (Other Vascular Procedures with CC) to the highest severity level MS-DRG 252 (Other Vascular Procedures with MCC). We also received a request to revise the title of MS-DRG 252 to ``Other Vascular Procedures with MCC or Drug- Coated Balloon Implant''. As discussed in the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20205), there are currently 36 ICD-10-PCS procedure codes that describe the performance of endovascular procedures involving treatment of the superficial femoral arteries that utilize a drug-coated balloon, which are listed in the following table. ------------------------------------------------------------------------ ICD-10-PCS code Code description ------------------------------------------------------------------------ 047K041...................

Dilation of left popliteal artery using drug- coated balloon, percutaneous endoscopic approach. ------------------------------------------------------------------------ The requestor performed its own analysis of claims data and expressed concern that it found that the average costs of cases using a drug-coated balloon in the performance of percutaneous endovascular procedures involving treatment of patients who have been diagnosed with peripheral arterial disease are significantly higher than the average costs of all of the cases in the MS-DRGs where these procedures are currently assigned. The requestor also expressed concern that payments may no longer be adequate because the new technology add-on payments have been discontinued and may affect patient access to these procedures. We first examined claims data from the September 2017 update of the FY 2017 MedPAR file for cases reporting any 1 of the 36 ICD-10-PCS procedure codes listed in the immediately preceding table that describe the use of a drug-coated balloon in the performance of endovascular procedures in MS-DRGs 252, 253, and 254. Our findings are shown in the following table. MS-DRGs for Other Vascular Procedures With Drug[dash]Coated Balloon ---------------------------------------------------------------------------------------------------------------- Number of Average length MS-DRG cases of stay Average costs ---------------------------------------------------------------------------------------------------------------- MS-DRG 252--All cases........................................... 33,583 7.6 $23,906 MS-DRG 252--Cases with drug-coated balloon...................... 870 8.8 30,912 MS-DRG 253--All cases........................................... 25,714 5.4 18,986 MS-DRG 253--Cases with drug-coated balloon...................... 1,532 5.4 23,051 MS-DRG 254--All cases........................................... 12,344 2.8 13,287 MS-DRG 254--Cases with drug-coated balloon...................... 488 2.4 17,445 ---------------------------------------------------------------------------------------------------------------- As shown in this table, there were a total of 33,583 cases in MS- DRG 252, with an average length of stay of 7.6 days and average costs of $23,906. There were 870 cases in MS-DRG 252 reporting the use of a drug-coated balloon in the performance of an endovascular procedure, with an average length of stay of 8.8 days and average costs of $30,912. The total number of cases in MS-DRG 253 was 25,714, with an average length of stay of 5.4 days and average costs of $18,986. There were 1,532 cases in MS-DRG 253 reporting the use of a DCB in the performance of an endovascular procedure, with an average length of stay of 5.4 days and average costs of $23,051. The total number of cases in MS-DRG 254 was 12,344, with an average length of stay of 2.8 days and average costs of $13,287. There were 488 cases in MS-DRG 254 reporting the use of a DCB in the performance of an endovascular procedure, with an average length of stay of 2.4 days and average costs of $17,445. The results of our data analysis show that there is not a very high volume of cases reporting the use of a drug-coated balloon in the performance of endovascular procedures compared to all of the cases in the assigned MS-DRGs. The data results also show that the average length of stay for cases reporting the use of a drug-coated balloon in the performance of endovascular procedures in MS-DRGs 253 and 254 is lower compared to the average length of stay for all of the cases in the assigned MS-DRGs, while the average length of stay for cases reporting the use of a drug-coated balloon in the performance of endovascular procedures in MS-DRG 252 is slightly higher compared to all of the cases in MS-DRG 252 (8.8 days versus 7.6 days). Lastly, the data results showed that the average costs for cases reporting the use of a drug-coated balloon in the performance of percutaneous endovascular procedures were higher compared to all of the cases in the assigned MS-DRGs. Specifically, for MS-DRG 252, the average costs for cases reporting the use of a DCB in the performance of endovascular procedures were $30,912 versus the average costs of $23,906 for all cases in MS-DRG 252, a difference of $7,006. For MS-DRG 253, the average costs for cases reporting the use of a drug-coated balloon in the performance of endovascular procedures were $23,051 versus the average costs of $18,986 for all cases in MS-DRG 253, a difference [[Page 41193]] of $4,065. For MS-DRG 254, the average costs for cases reporting the use of a drug-coated balloon in the performance of endovascular procedures were $17,445 versus the average costs of $13,287 for all cases in MS-DRG 254, a difference of $4,158. The following table is a summary of the findings discussed above from our review of MS-DRGs 252, 253 and 254 and the total number of cases that used a drug-coated balloon in the performance of the procedure across MS-DRGs 252, 253, and 254. MS-DRGs for Other Vascular Procedures and Cases With Drug-Coated Balloon ---------------------------------------------------------------------------------------------------------------- Number of Average length MS-DRG cases of stay Average costs ---------------------------------------------------------------------------------------------------------------- MS-DRGs 252, 253, and 254--All cases............................ 71,641 6.0 $20,310 MS-DRGs 252, 253, and 254--Cases with drug-coated balloon....... 2,890 6.0 24,569 ---------------------------------------------------------------------------------------------------------------- As shown in this table, there were a total of 71,641 cases across MS-DRGs 252, 253, and 254, with an average length of stay of 6.0 days and average costs of $20,310. There were a total of 2,890 cases across MS-DRGs 252, 253, and 254 reporting the use of a drug-coated balloon in the performance of the procedure, with an average length of stay of 6.0 days and average costs of $24,569. The data analysis showed that cases reporting the use of a drug-coated balloon in the performance of the procedure across MS-DRGs 252, 253 and 254 have similar lengths of stay (6.0 days) compared to the average length of stay for all of the cases in MS-DRGs 252, 253, and 254. The data results also showed that the cases reporting the use of a drug-coated balloon in the performance of the procedure across these MS-DRGs have higher average costs ($24,569 versus $20,310) compared to the average costs for all of the cases across these MS-DRGs. We stated in the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20207) that the results of our claims data analysis and the advice from our clinical advisors did not support reassigning cases reporting the use of a drug-coated balloon in the performance of these procedures from the lower severity level MS-DRGs 253 and 254 to the highest severity level MS-DRG 252 at this time. We further stated that, if we were to reassign cases that utilize a drug-coated balloon in the performance of these types of procedures from MS-DRG 254 to MS-DRG 252, the cases would result in overpayment and also would have a shorter length of stay compared to all of the cases in MS-DRG 252. While the cases reporting the use of a drug-coated balloon in the performance of these procedures are higher compared to the average costs for all cases in their assigned MS-DRGs, it is not by a significant amount. We stated that we believe that as use of a drug-coated balloon becomes more common, the costs will be reflected in the data. Our clinical advisors also agreed that it would not be clinically appropriate to reassign cases for patients from the lowest severity level (without CC/MCC) MS- DRG to the highest severity level (with MCC) MS-DRG in the absence of additional data to better determine the resource utilization for this subset of patients. Therefore, for these reasons, we proposed to not reassign cases reporting the use of a drug-coated balloon in the performance of endovascular procedures from MS-DRGs 253 and 254 to MS- DRG 252. Comment: A number of commenters supported maintaining the current classification of cases involving the use of a drug-coated balloon in the performance of endovascular procedures. The commenters stated that CMS' proposal was reasonable, given the data, ICD-10-PCS procedure codes, and information provided. Response: We appreciate the commenters' support. Comment: One commenter recommended that further data analysis be conducted after the new ICD-10-PCS procedure codes for endovascular procedures utilizing a drug-coated balloon in the upper extremity become effective on October 1, 2018, in order to determine if MS-DRG structure and assignment modifications are warranted in the future. Response: We agree with the commenter that continued monitoring of the cases reporting the use of a drug-coated balloon in the performance of endovascular procedures in the lower extremity, along with analysis of the new ICD-10-PCS procedure codes that identify the use of a drug- coated balloon in the upper extremity, would be advantageous. As claims data become available, we will be able to evaluate the resource utilization of these procedures more effectively. Comment: One commenter believed that an analysis of the average costs of cases performed with and without the use of drug-coated balloons in MS-DRGs 252, 253, and 254 justified assigning cases, including cases involving the use of drug-coated balloons in the performance of the procedure, to MS-DRGs 252 or 253, and not to MS-DRG 254. The commenter indicated that claims data showed the average costs of MS-DRG 253 for all cases is $18,986, while the average cost of cases utilizing drug-coated balloons in the performance of the procedure assigned to MS-DRG 254 is $17,445. The commenter believed that, while the average length-of-stay is lower for these cases, the average costs are consistent with that of MS-DRG 253. Therefore, the commenter suggested that CMS reassign these cases to MS-DRG 253 as a more appropriate reflection of the hospital resources utilized for these cases. Response: Our clinical advisors reviewed the data, and again determined that it would not be clinically appropriate to reassign cases for patients from the lowest severity level (without CC/MCC) MS- DRG to the higher severity level (with CC) MS-DRG in the absence of additional data to better determine the resource utilization for this subset of patients. We reiterate that we believe as use of the drug- coated balloon in the performance of endovascular procedures becomes more common, the costs will be reflected in the data. In addition, as noted above, new ICD-10-PCS procedure codes that describe the use of a drug-coated balloon in the upper extremity are effective with discharges occurring on or after October 1, 2018. As such, we will continue to monitor cases reporting the use of a drug-coated balloon in the performance of endovascular procedures and determine if future MS- DRG structure and assignment modifications are supported. After consideration of the public comments we received, we are finalizing our proposal to not reassign cases reporting the use of a drug-coated balloon in the performance of endovascular procedures from MS-DRGs 253 and 254 to MS-DRG 252 for FY 2019. We noted in the proposed rule that because 24 of the 36 ICD-10-PCS procedure codes describing the use of a [[Page 41194]] drug-coated balloon in the performance of endovascular procedures also include the use of an intraluminal device, we conducted further analysis to determine the number of cases reporting an intraluminal device with the use of a drug-coated balloon in the performance of the procedure versus the number of cases reporting the use of a drug-coated balloon alone. We analyzed the number of cases across MS-DRGs 252, 253, and 254 reporting: (1) The use of an intraluminal device (stent) with use of a drug-coated balloon in the performance of the procedure; (2) the use of a drug-eluting intraluminal device (stent) with the use of a drug-coated balloon in the performance of the procedure; and (3) the use of a drug-coated balloon only in the performance of the procedure. Our findings are shown in the following table. MS-DRGs for Other Vascular Procedures and Cases With Drug-Coated Balloon ---------------------------------------------------------------------------------------------------------------- Number of Average length MS-DRG cases of stay Average costs ---------------------------------------------------------------------------------------------------------------- MS-DRGs 252, 253 and 254--All cases............................. 71,641 6.0 $20,310 MS-DRGs 252, 253 and 254--Cases with intraluminal device with 522 6.0 28,418 drug-coated balloon............................................ MS-DRGs 252, 253 and 254--Cases with drug-eluting intraluminal 447 6.0 26,098 device with drug-coated balloon................................ MS-DRGs 252, 253 and 254--Cases with drug-coated balloon only... 2,705 6.1 24,553 ---------------------------------------------------------------------------------------------------------------- As shown in this table, there were a total of 71,641 cases across MS-DRGs 252, 253, and 254, with an average length of stay of 6.0 days and average costs of $20,310. There were 522 cases across MS-DRGs 252, 253, and 254 reporting the use of an intraluminal device with use of a drug-coated balloon in the performance of the procedure, with an average length of stay of 6.0 days and average costs of $28,418. There were 447 cases across MS-DRGs 252, 253, and 254 reporting the use of a drug-eluting intraluminal device with use of a drug-coated balloon in the performance of the procedure, with an average length of stay of 6.0 days and average costs of $26,098. Lastly, there were 2,705 cases across MS-DRGs 252, 253, and 254 reporting the use of a drug-coated balloon alone in the performance of the procedure, with an average length of stay of 6.1 days and average costs of $24,553. The data showed that the 2,705 cases in MS-DRGs 252, 253, and 254 reporting the use of a drug-coated balloon alone in the performance of the procedure have lower average costs compared to the 969 cases in MS- DRGs 252, 253, and 254 reporting the use of an intraluminal device (522 cases) or a drug-eluting intraluminal device (447 cases) with a drug- coated balloon in the performance of the procedure ($24,553 versus $28,418 and $26,098, respectively.) The data also showed that the cases reporting the use of a drug-coated balloon alone in the performance of the procedure have a comparable average length of stay compared to the cases reporting the use of an intraluminal device or a drug-eluting intraluminal device with a drug-coated balloon in the performance of the procedure (6.1 days versus 6.0 days). In summary, as we stated in the proposed rule, we believe that further analysis of endovascular procedures involving the treatment of superficial femoral arteries for peripheral arterial disease that utilize a drug-coated balloon in the performance of the procedure would be advantageous. As additional claims data become available, we will be able to more fully evaluate the differences in cases where a procedure utilizes a drug-coated balloon alone in the performance of the procedure versus cases where a procedure utilizes an intraluminal device or a drug-eluting intraluminal device in addition to a drug- coated balloon in the performance of the procedure. 5. MDC 6 (Diseases and Disorders of the Digestive System) a. Benign Lipomatous Neoplasm of Kidney As discussed in the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20207), we received a request to reassign ICD-10-CM diagnosis code D17.71 (Benign lipomatous neoplasm of kidney) from MDC 06 (Diseases and Disorders of the Digestive System) to MDC 11 (Diseases and Disorders of the Kidney and Urinary Tract). The requestor stated that this diagnosis code is used to describe a kidney neoplasm and believed that because the ICD-10-CM code is specific to the kidney, a more appropriate assignment would be under MDC 11. In FY 2015, under the ICD-9-CM classification, there was not a specific diagnosis code for a benign lipomatous neoplasm of the kidney. The only diagnosis code available was ICD-9-CM diagnosis code 214.3 (Lipoma of intra-abdominal organs), which was assigned to MS-DRGs 393, 394, and 395 (Other Digestive System Diagnoses with MCC, with CC, and without CC/MCC, respectively) under MDC 6. Therefore, when we converted from the ICD-9 based MS-DRGs to the ICD-10 MS-DRGs, there was not a specific code available that identified the kidney from which to replicate. As a result, ICD-10-CM diagnosis code D17.71 was assigned to those same MS-DRGs (MS-DRGs 393, 394, and 395) under MDC 6. While reviewing the MS-DRG classification of ICD-10-CM diagnosis code D17.71, we also reviewed the MS-DRG classification of another diagnosis code organized in subcategory D17.7, ICD-10-CM diagnosis code D17.72 (Benign lipomatous neoplasm of other genitourinary organ). ICD- 10-CM diagnosis code D17.72 is currently assigned under MDC 09 (Diseases and Disorders of the Skin, Subcutaneous Tissue and Breast) to MS-DRGs 606 and 607 (Minor Skin Disorders with and without MCC, respectively). Similar to the replication issue with ICD-10-CM diagnosis code D17.71, with ICD-10-CM diagnosis code D17.72, under the ICD-9-CM classification, there was not a specific diagnosis code to identify a benign lipomatous neoplasm of genitourinary organ. The only diagnosis code available was ICD-9-CM diagnosis code 214.8 (Lipoma of other specified sites), which was assigned to MS-DRGs 606 and 607 under MDC 09. Therefore, when we converted from the ICD-9 based MS-DRGs to the ICD-10 MS-DRGs, there was not a specific code available that identified another genitourinary organ (other than the kidney) from which to replicate. As a result, ICD-10-CM diagnosis code D17.72 was assigned to those same MS-DRGs (MS-DRGs 606 and 607) under MDC 9. In the proposed rule, we proposed to reassign ICD-10-CM diagnosis code D17.71 from MS-DRGs 393, 394, and 395 (Other Digestive System Diagnoses with MCC, with CC, and without CC/MCC, respectively) under MDC 06 to [[Page 41195]] MS-DRGs 686, 687, and 688 (Kidney and Urinary Tract Neoplasms with MCC, with CC, and without CC/MCC, respectively) under MDC 11 because this diagnosis code is used to describe a kidney neoplasm. We also proposed to reassign ICD-10-CM diagnosis code D17.72 from MS-DRGs 606 and 607 under MDC 09 to MS-DRGs 686, 687, and 688 under MDC 11 because this diagnosis code is used to describe other types of neoplasms classified to the genitourinary tract that do not have a specific code identifying the site. Our clinical advisors agreed that the conditions described by the ICD-10-CM diagnosis codes provide specific anatomic detail involving the kidney and genitourinary tract and, therefore, if reclassified under this proposed MDC and reassigned to these MS-DRGs, would improve the clinical coherence of the patients assigned to these groups. Comment: Commenters agreed with CMS' proposals to reassign ICD-10- CM diagnosis code D17.71 that describes benign lipomatous neoplasm of the kidney from MDC 6 to MDC 11, and to reassign ICD-10-CM diagnosis code D17.72 that describes benign lipomatous neoplasm of other genitourinary tract organ from MDC 9 to MDC 11. The commenters stated the proposals were reasonable, given the ICD-10-CM diagnosis codes and information provided. Response: We appreciate the commenters' support. After consideration of the public comments we received, we are finalizing our proposals to reassign ICD-10-CM diagnosis code D17.71 from MS-DRGs 393, 394, and 395 under MDC 6 to MS-DRGs 686, 687, and 688 under MDC 11, and to reassign ICD-10-CM diagnosis code D17.72 from MS- DRGs 606 and 607 under MDC 9 to MS-DRGs 686, 687, and 688 under MDC 11 in the ICD-10 MS-DRGs Version 36, effective October 1, 2018. b. Bowel Procedures As discussed in the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20208), we received a request to reassign the following 8 ICD-10-PCS procedure codes that describe repositioning of the colon and takedown of end colostomy from MS-DRGs 344, 345, and 346 (Minor Small and Large Bowel Procedures with MCC, with CC, and without CC/MCC, respectively) to MS-DRGs 329, 330, and 331 (Major Small and Large Bowel Procedures with MCC, with CC, and without CC/MCC, respectively): ------------------------------------------------------------------------ ICD-10-PCS code Code description ------------------------------------------------------------------------ 0DSK0ZZ................... Reposition ascending colon, open approach. 0DKL4ZZ................... Reposition ascending colon, percutaneous endoscopic approach. 0DSL0ZZ................... Reposition transverse colon, open approach. 0DSL4ZZ................... Reposition transverse colon, percutaneous endoscopic approach. 0DSM0ZZ................... Reposition descending colon, open approach. 0DSM4ZZ................... Reposition descending colon, percutaneous endoscopic approach. 0DSN0ZZ................... Reposition sigmoid colon, open approach. 0DSN4ZZ................... Reposition sigmoid colon, percutaneous endoscopic approach. ------------------------------------------------------------------------ The requestor indicated that the resources required for procedures identifying repositioning of specified segments of the large bowel are more closely aligned with other procedures that group to MS-DRGs 329, 330, and 331, such as repositioning of the large intestine (unspecified segment). We analyzed the claims data from the September 2017 update of the FY 2017 Med PAR file for MS-DRGs 344, 345 and 346 for all cases reporting the 8 ICD-10-PCS procedure codes listed in the table above. Our findings are shown in the following table: ---------------------------------------------------------------------------------------------------------------- Number of Average length MS-DRG cases of stay Average costs ---------------------------------------------------------------------------------------------------------------- MS-DRG 344--All cases........................................... 1,452 9.5 $20,609 MS-DRG 344--All cases with a specific large bowel reposition 52 9.6 23,409 procedure...................................................... MS-DRG 345--All cases........................................... 2,674 5.6 11,552 MS-DRG 345--All cases with a specific large bowel reposition.... 246 6 14,915 MS-DRG 346--All cases........................................... 990 3.8 8,977 MS-DRG 346--All cases with a specific large bowel reposition 223 4.5 12,279 procedure...................................................... ---------------------------------------------------------------------------------------------------------------- The data showed that the average length of stay and average costs for cases that reported a specific large bowel reposition procedure were generally consistent with the average length of stay and average costs for all of the cases in their assigned MS-DRG. We then examined the claims data in the September 2017 update of the FY 2017 MedPAR file for MS-DRGs 329, 330 and 331. Our findings are shown in the following table. ---------------------------------------------------------------------------------------------------------------- Number of Average length MS-DRG cases of stay Average costs ---------------------------------------------------------------------------------------------------------------- MS-DRGs 329, 330, and 331--All cases............................ 112,388 8.4 $21,382 MS-DRG 329--All cases........................................... 33,640 13.3 34,015 MS-DRG 330--All cases........................................... 52,644 7.3 17,896 MS-DRG 331--All cases........................................... 26,104 4.1 12,132 ---------------------------------------------------------------------------------------------------------------- [[Page 41196]] As shown in this table, across MS-DRGs 329, 330, and 331, we found a total of 112,388 cases, with an average length of stay of 8.4 days and average costs of $21,382. We stated in the FY 2019 IPPS/LTCH PPS proposed rule that the results of our analysis indicate that the resources required for cases reporting the specific large bowel repositioning procedures are more aligned with those resources required for all cases assigned to MS-DRGs 344, 345, and 346, with the average costs being lower than the average costs for all cases assigned to MS- DRGs 329, 330, and 331. Our clinical advisors also indicated that the 8 specific bowel repositioning procedures are best aligned with those in MS-DRGs 344, 345, and 346. Therefore, in the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20209), we proposed to maintain the current assignment of the 8 specific bowel repositioning procedures in MS-DRGs 344, 345, and 346 for FY 2019. Comment: Commenters supported CMS' proposal to maintain the current assignment of the 8 specific bowel repositioning procedures in MS DRGs 344, 345, and 346 for FY 2019. Response: We appreciate the commenters' support. After consideration of the public comments we received, we are finalizing our proposal to maintain the current assignment of the 8 specific bowel repositioning procedures in MS DRGs 344, 345, and 346 for FY 2019. In conducting our analysis of MS-DRGs 329, 330, and 331, we also examined the subset of cases reporting one of the bowel procedures listed in the following table as the only O.R. procedure. ------------------------------------------------------------------------ ICD-10-PCS code Code description ------------------------------------------------------------------------ 0DQK0ZZ................... Repair ascending colon, open approach. 0DQK4ZZ................... Repair ascending colon, percutaneous endoscopic approach. 0DQL0ZZ................... Repair transverse colon, open approach. 0DQL4ZZ................... Repair transverse colon, percutaneous endoscopic approach. 0DQM0ZZ................... Repair descending colon, open approach. 0DQM4ZZ................... Repair descending colon, percutaneous endoscopic approach. 0DQN0ZZ................... Repair sigmoid colon, open approach. 0DQN4ZZ................... Repair sigmoid colon, percutaneous endoscopic approach. 0DSB0ZZ................... Reposition ileum, open approach. 0DSB4ZZ................... Reposition ileum, percutaneous endoscopic approach. 0DSE0ZZ................... Reposition large intestine, open approach. 0DSE4ZZ................... Reposition large intestine, percutaneous endoscopic approach. ------------------------------------------------------------------------ This approach can be useful in determining whether resource use is truly associated with a particular procedure or whether the procedure frequently occurs in cases with other procedures with higher than average resource use. As shown in the following table, we identified 398 cases reporting a bowel procedure as the only O.R. procedure, with an average length of stay of 6.3 days and average costs of $13,595 across MS-DRGs 329, 330, and 331, compared to the overall average length of stay of 8.4 days and average costs of $21,382 for all cases in MS-DRGs 329, 330, and 331. ---------------------------------------------------------------------------------------------------------------- Number of Average length MS-DRG cases of stay Average costs ---------------------------------------------------------------------------------------------------------------- MS-DRGs 329, 330 and 331--All cases............................. 112,388 8.4 $21,382 MS-DRGs 329, 330 and 331--All cases with a bowel procedure as 398 6.3 13,595 only O.R. procedure............................................ MS-DRG 329--All cases........................................... 33,640 13.3 34,015 MS-DRG 329--Cases with a bowel procedure as only O.R. procedure. 86 8.3 19,309 MS-DRG 330--All cases........................................... 52,644 7.3 17,896 MS-DRG 330--Cases with a bowel procedure as only O.R. procedure. 183 6.9 13,617 MS-DRG 331--All cases........................................... 26,104 4.1 12,132 MS-DRG 331--Cases with a bowel procedure as only O.R. procedure. 129 4.3 9,754 ---------------------------------------------------------------------------------------------------------------- We stated in the FY 2019 IPPS/LTCH PPS proposed rule that the resources required for these cases are more aligned with the resources required for cases assigned to MS-DRGs 344, 345, and 346 than with the resources required for cases assigned to MS-DRGs 329, 330, and 331. Our clinical advisors also agreed that these cases are more clinically aligned with cases in MS-DRGs 344, 345, and 346, as they are minor procedures relative to the major bowel procedures assigned to MS-DRGs 329, 330, and 331. Therefore, in the proposed rule, we proposed to reassign the 12 ICD-10-PCS procedure codes listed above from MS-DRGs 329, 330, and 331 to MS-DRGs 344, 345, and 346. Comment: Commenters disagreed with CMS' proposal to reassign the 12 ICD-10-PCS procedure codes listed above from MS-DRGs 329, 330, and 331 to MS DRGs 344, 345, and 346. The commenters recommended that changes to these MS-DRGs be delayed until a thorough data analysis is conducted. The commenters further recommended that any future analysis include a thorough review of the principal diagnoses for cases involving these ICD-10-PCS codes, as the associated diagnosis significantly impacts the resource utilization and complexity of the procedure performed and MS-DRG assignment. The commenters noted that the root operation of ``Reposition'' may be used for the takedown of a stoma, as well as to treat a specific medical condition such as malrotation of the intestine, and that ``Repair'' is the root operation of last resort when no other ICD-10-PCS root operation applies and, therefore, is used for a wide range of procedures of varying complexity. Commenters also noted that several questions and answers regarding these ICD-10-PCS procedure codes were published in Coding Clinic for ICD-10-CM/PCS between late 2016 and the end of 2017, and stated that because 2 full [[Page 41197]] years of data were not available subsequent to publication of this advice, CMS' analysis and proposed MS-DRG modifications may be based on unreliable data. Response: Upon further review, we agree with the commenters that the availability of a full 2 years of data would allow us to conduct a more comprehensive analysis upon which to consider potential modifications to these MS-DRGs. Therefore, we believe it would be preferable to wait until these data are available before finalizing changes to the MS-DRG assignment for these bowel procedures. After consideration of the public comments we received, we are not finalizing our proposal to reassign the 12 ICD-10-PCS procedure codes listed above from MS-DRGs 329, 330, and 331 to MS-DRGs 344, 345, and 346 for FY 2019. 6. MDC 8 (Diseases and Disorders of the Musculoskeletal System and Connective Tissue): Spinal Fusion In the FY 2018 IPPS/LTCH PPS final rule (82 FR 38036), we announced our plans to review the ICD-10 logic for the MS-DRGs where procedures involving spinal fusion are currently assigned for FY 2019. After publication of the FY 2018 IPPS/LTCH PPS final rule, we received a comment suggesting that CMS publish findings from this review and discuss possible future actions. The commenter agreed that it is important to be able to fully evaluate the MS-DRGs to which all spinal fusion procedures are currently assigned with additional claims data, particularly considering the 33 clinically invalid codes that were identified through the rulemaking process (82 FR 38034 through 38035) and the 87 codes identified from the upper and lower joint fusion tables in the ICD-10-PCS classification and discussed at the September 12, 2017 ICD-10 Coordination and Maintenance Committee that were proposed to be deleted effective October 1, 2018 (FY 2019). The agenda and handouts from that meeting can be obtained from the CMS website at: https://www.cms.gov/Medicare/Coding/ICD9ProviderDiagnosticCodes/ICD-9-CM-C-and-M-Meeting-Materials.html. According to the commenter, deleting the 33 procedure codes describing clinically invalid spinal fusion procedures for FY 2018 partially resolves the issue for data used in setting the FY 2020 payment rates. However, the commenter also noted that the problem will not be fully resolved until the FY 2019 claims are available for FY 2021 ratesetting (due to the 87 codes identified at the ICD-10 Coordination and Maintenance Committee meeting for deletion effective October 1, 2018 (FY 2019)). The commenter noted that it analyzed claims data from the FY 2016 MedPAR data set and was surprised to discover a significant number of discharges reporting 1 of the 87 clinically invalid codes that were identified and discussed by the ICD-10 Coordination and Maintenance Committee among the following spinal fusion MS-DRGs. ------------------------------------------------------------------------ MS-DRG Description ------------------------------------------------------------------------ 453....................... Combined Anterior/Posterior Spinal Fusion with MCC. 454....................... Combined Anterior/Posterior Spinal Fusion with CC. 455....................... Combined Anterior/Posterior Spinal Fusion without CC/MCC. 456....................... Spinal Fusion Except Cervical with Spinal Curvature or Malignancy or Infection or Extensive Fusions with MCC. 457....................... Spinal Fusion Except Cervical with Spinal Curvature or Malignancy or Infection or Extensive Fusions with CC. 458....................... Spinal Fusion Except Cervical with Spinal Curvature or Malignancy or Infection or Extensive Fusions without CC/MCC. 459....................... Spinal Fusion Except Cervical with MCC. 460....................... Spinal Fusion Except Cervical without MCC. 471....................... Cervical Spinal Fusion with MCC. 472....................... Cervical Spinal Fusion with CC. 473....................... Cervical Spinal Fusion without CC/MCC. ------------------------------------------------------------------------ In addition, the commenter noted that it also identified a number of discharges for the 33 clinically invalid codes we identified in the FY 2018 IPPS/LTCH PPS final rule in the same MS-DRGs listed above. According to the commenter, its findings of these invalid spinal fusion procedure codes in the FY 2016 claims data comprise approximately 30 percent of all discharges for spinal fusion procedures. The commenter expressed its appreciation that CMS is making efforts to address coding inaccuracies within the classification and suggested that CMS publish findings from its own review of spinal fusion coding issues in those MS-DRGs where cases reporting spinal fusion procedures are currently assigned and include a discussion of possible future actions in the FY 2019 IPPS/LTCH PPS proposed rule. The commenter believed that such an approach would allow time for stakeholder input on any possible proposals along with time for the invalid codes to be worked out of the datasets. The commenter also noted that publishing CMS' findings will put the agency, as well as the public, in a better position to address any potential payment issues for these services beginning in FY 2021. In the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20210), we thanked the commenter for acknowledging the steps we have taken in our efforts to address coding inaccuracies within the classification as we continue to refine the ICD-10 MS-DRGs. We did not propose any changes to the MS-DRGs involving spinal fusion procedures for FY 2019. However, in response to the commenter's suggestion and findings, we provided the following results from our analysis of the September 2017 update of the FY 2017 MedPAR claims data for the MS-DRGs involving spinal fusion procedures. We noted that while the commenter stated that 87 codes were identified from the upper and lower joint fusion tables in the ICD-10- PCS classification and discussed at the September 12, 2017 ICD-10 Coordination and Maintenance Committee meeting to be deleted effective October 1, 2018 (FY 2019), there were 99 spinal fusion codes identified in the meeting materials, as shown in Table 6P.1g associated with the proposed rule (which is available via the internet on the CMS website at: http://www.cms.hhs.gov/Medicare/Medicare-Fee-for-Service-Payment/AcuteInpatientPPS/index.html). As shown in Table 6P.1g associated with the proposed rule, the 99 procedure codes describe spinal fusion procedures that have device value ``Z'' representing No Device for the 6th character in the code. Because a spinal fusion procedure always requires some type of device (for example, instrumentation with bone graft or bone [[Page 41198]] graft alone) to facilitate the fusion of vertebral bones, these codes are considered clinically invalid and were proposed for deletion at the September 12, 2017 ICD-10 Coordination and Maintenance Committee meeting. We received public comments in support of the proposal to delete the 99 codes describing a spinal fusion without a device, in addition to receiving support for the deletion of other procedure codes describing fusion of body sites other than the spine. A total of 213 procedure codes describing fusion of a specific body part with device value ``Z'' No Device are being deleted effective October 1, 2018 (FY 2019) as shown in Table 6D.--Invalid Procedure Codes associated with the proposed rule and this final rule (which is available via the internet on the CMS website at: http://www.cms.hhs.gov/Medicare/Medicare-Fee-for-Service-Payment/AcuteInpatientPPS/index.html). We examined claims data from the September 2017 update of the FY 2017 MedPAR file for cases reporting any of the clinically invalid spinal fusion procedures with device value ``Z'' No Device in MS-DRGs 028 (Spinal Procedures with MCC), 029 (Spinal Procedures with CC or Spinal Neurostimulators), and 030 (Spinal Procedures without CC/MCC) under MDC 1 and MS-DRGs 453, 454, 455, 456, 457, 458, 459, 460, 471, 472, and 473 under MDC 8 (that are listed and shown earlier in this section). Our findings are shown in the following tables. Spinal Fusion Procedures ---------------------------------------------------------------------------------------------------------------- Number of Average length MS-DRG cases of stay Average costs ---------------------------------------------------------------------------------------------------------------- MS-DRG 028--All cases........................................... 1,927 11.7 $37,524 MS-DRG 028--Cases with invalid spinal fusion procedures......... 132 13 52,034 MS-DRG 029--All cases........................................... 3,426 5.7 22,525 MS-DRG 029--Cases with invalid spinal fusion procedures......... 171 7.4 33,668 MS-DRG 030--All cases........................................... 1,578 3 15,984 MS-DRG 030--Cases with invalid spinal fusion procedures......... 52 2.6 22,471 MS-DRG 453--All cases........................................... 2,891 9.5 70,005 MS-DRG 453--Cases with invalid spinal fusion procedures......... 823 10.1 84,829 MS-DRG 454--All cases........................................... 12,288 4.7 47,334 MS-DRG 454--Cases with invalid spinal fusion procedures......... 2,473 5.4 59,814 MS-DRG 455--All cases........................................... 12,751 3 37,440 MS-DRG 455--Cases with invalid spinal fusion procedures......... 2,332 3.2 45,888 MS-DRG 456--All cases........................................... 1,439 11.5 66,447 MS-DRG 456--Cases with invalid spinal fusion procedures......... 404 12.5 71,385 MS-DRG 457--All cases........................................... 3,644 6 48,595 MS-DRG 457--Cases with invalid spinal fusion procedures......... 960 6.7 53,298 MS-DRG 458--All cases........................................... 1,368 3.6 37,804 MS-DRG 458--Cases with invalid spinal fusion procedures......... 244 4.1 43,182 MS-DRG 459--All cases........................................... 4,904 7.8 43,862 MS-DRG 459--Cases with invalid spinal fusion procedures......... 726 9 49,387 MS-DRG 460--All cases........................................... 59,459 3.4 29,870 MS-DRG 460--Cases with invalid spinal fusion procedures......... 5,311 3.9 31,936 MS-DRG 471--All cases........................................... 3,568 8.4 36,272 MS-DRG 471--Cases with invalid spinal fusion procedures......... 389 9.9 43,014 MS-DRG 472--All cases........................................... 15,414 3.2 21,836 MS-DRG 472--Cases with invalid spinal fusion procedures......... 1,270 4 25,780 MS-DRG 473--All cases........................................... 18,095 1.8 17,694 MS-DRG 473--Cases with invalid spinal fusion procedures......... 1,185 2.3 19,503 ---------------------------------------------------------------------------------------------------------------- Summary Table for Spinal Fusion Procedures ---------------------------------------------------------------------------------------------------------------- Number of Average length MS-DRG cases of stay Average costs ---------------------------------------------------------------------------------------------------------------- MS-DRGs 028, 029, 030, 453, 454, 455, 456, 457, 458, 459, 460, 142,752 3.9 $31,788 471, 472, and 473--All cases................................... MS-DRGs 028, 029, 030, 453, 454, 455, 456, 457, 458, 459, 460, 16,472 5.1 42,929 471, 472, and 473--Cases with invalid spinal fusion procedures. ---------------------------------------------------------------------------------------------------------------- As shown in this summary table, we found a total of 142,752 cases in MS-DRGs 028, 029, 030, 453, 454, 455, 456, 457, 458, 459, 460, 471, 472, and 473 with an average length of stay of 3.9 days and average costs of $31,788. We found a total of 16,472 cases reporting a procedure code for an invalid spinal fusion procedure with device value ``Z'' No Device across MS-DRGs 028, 029, and 030 under MDC 1 and MS- DRGs 453, 454, 455, 456, 457, 458, 459, 460, 471, 472, and 473 under MDC 8, with an average length of stay of 5.1 days and average costs of $42,929. The results of the data analysis demonstrate that these invalid spinal fusion procedures represent approximately 12 percent of all discharges across the spinal fusion MS-DRGs. Because these procedure codes describe clinically invalid procedures, we would not expect these codes to be reported on any claims data. We stated in the proposed rule that it is unclear why providers assigned procedure codes for spinal fusion procedures with the device value ``Z'' No Device. Our analysis did not examine whether these claims were isolated to a specific provider or whether this inaccurate reporting was widespread among a number of providers. [[Page 41199]] With regard to possible future action, we indicated in the proposed rule that we will continue to monitor the claims data for resolution of the coding issues previously identified. Because the procedure codes that we analyzed and presented findings for in the FY 2019 IPPS/LTCH PPS proposed rule will no longer be in the classification system, effective October 1, 2018 (FY 2019), the claims data that we examine for FY 2020 may still contain claims with the invalid codes. As such, we will continue to collaborate with the AHA as one of the four Cooperating Parties through the AHA's Coding Clinic for ICD-10-CM/PCS and provide further education on spinal fusion procedures and the proper reporting of the ICD-10-PCS spinal fusion procedure codes. We agreed with the commenter that until these coding inaccuracies are no longer reflected in the claims data, it would be premature to propose any MS-DRG modifications for spinal fusion procedures. Possible MS-DRG modifications may include taking into account the approach that was utilized in performing the spinal fusion procedure (for example, open versus percutaneous). For the reasons described and as stated in the proposed rule and earlier in our discussion, we proposed not to make any changes to the spinal fusion MS-DRGs for FY 2019. Comment: Commenters agreed with CMS' proposal not to make any changes to the MS-DRGs involving spinal fusion procedures for FY 2019. Response: We thank the commenters for their support. Comment: Some commenters noted that confusion has existed as to whether a spinal fusion code may be assigned when no bone graft or bone graft substitute is used (that is, instrumentation only) but the medical record documentation refers to the procedure as a spinal fusion. One commenter recommended that additional refinements be made to the ICD-10-PCS spinal fusion coding guidelines in order to further clarify appropriate reporting of spinal fusion codes. Another commenter asserted that the planned deletion of a total of 213 ICD-10-PCS fusion procedure codes with the device value ``Z'' for ``no device'', effective October 1, 2018, should help remedy the confusion regarding the correct coding of spinal procedures. Response: We agree with the commenters that accurate coding of spinal fusion procedures has been the subject of confusion in the past, and we will continue to monitor the claims data for spinal fusion procedures. As one of the four Cooperating Parties, we also will continue to collaborate with the American Hospital Association to provide guidance for coding spinal fusion procedures through the Coding Clinic for ICD-10-CM/PCS publication and to review the ICD-10-PCS spinal fusion coding guidelines to determine where further clarifications may be made. After consideration of the public comments we received, we are finalizing our proposal to not make any changes to the spinal fusion MS-DRGs for FY 2019. 7. MDC 9 (Diseases and Disorders of the Skin, Subcutaneous Tissue and Breast): Cellulitis With Methicillin Resistant Staphylococcus Aureus (MRSA) Infection As discussed in the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20212), we received a request to reassign ICD-10-CM diagnosis codes reported with a principal diagnosis of cellulitis and a secondary diagnosis code of B95.62 (Methicillin resistant Staphylococcus aureus infection as the cause of diseases classified elsewhere) or A49.02 (Methicillin resistant Staphylococcus aureus infection, unspecified site). Currently, these cases are assigned to MS-DRG 602 (Cellulitis with MCC) and MS-DRG 603 (Cellulitis without MCC) in MDC 9. The requestor believed that cases of cellulitis with MSRA infection should be reassigned to MS-DRG 867 (Other Infectious and Parasitic Diseases Diagnoses with MCC) because MS-DRGs 602 and 603 include cases that do not accurately reflect the severity of illness or risk of mortality for patients diagnosed with cellulitis and MRSA. The requestor acknowledged that the organism is not to be coded before the localized infection, but stated in its request that patients diagnosed with cellulitis and MRSA are entirely different from patients diagnosed only with cellulitis. The requestor stated that there is a genuine threat to life or limb in these cases. The requestor further stated that, with the opioid crisis and the frequency of MRSA infection among this population, cases of cellulitis with MRSA should be identified with a specific combination code and assigned to MS-DRG 867. For the FY 2019 IPPS/LTCH PPS proposed rule, we analyzed claims data from the September 2017 update of the FY 2017 MedPAR file for all cases assigned to MS-DRGs 602 and 603 and subsets of these cases reporting a principal ICD-10-CM diagnosis of cellulitis and a secondary diagnosis code of B95.62 or A49.02. Our findings are shown in the following table. ---------------------------------------------------------------------------------------------------------------- Number of Average length MS-DRG cases of stay Average costs ---------------------------------------------------------------------------------------------------------------- MS-DRG 602--All cases........................................... 26,244 5.8 $10,034 MS-DRG 603--All cases........................................... 104,491 3.9 6,128 MS-DRGs 602 and 603--Cases reported with a principal diagnosis 5,364 5.3 8,245 of cellulitis and a secondary diagnosis of B95.62.............. MS-DRGs 602 and 603--Cases reported with a principal diagnosis 309 5.4 8,832 of cellulitis and a secondary diagnosis of A49.02.............. ---------------------------------------------------------------------------------------------------------------- As shown in this table, we examined the subsets of cases in MS-DRGs 602 and 603 reported with a principal diagnosis of cellulitis and a secondary diagnosis code B95.62 or A49.02. Both of these subsets of cases had an average length of stay that was comparable to the average length of stay for all cases in MS-DRG 602 and greater than the average length of stay for all cases in MS-DRG 603, and average costs that were lower than the average costs of all cases in MS-DRG 602 and higher than the average costs of all cases in MS-DRG 603. As we have discussed in prior rulemaking (77 FR 53309), it is a fundamental principle of an averaged payment system that half of the procedures in a group will have above average costs. It is expected that there will be higher cost and lower cost subsets, especially when a subset has low numbers. To examine the request to reassign ICD-10-CM diagnosis codes reported with a principal diagnosis of cellulitis and a secondary diagnosis code of B95.62 or A49.02 from MS-DRGs 602 and 603 to MS-DRG 867 (which would typically involve also reassigning those cases to the two other severity level MS-DRGs 868 and 869 (Other Infectious [[Page 41200]] and Parasitic Diseases Diagnoses with CC and Other Infectious and Parasitic Diseases Diagnoses without CC/MCC, respectively)), we then analyzed the data for all cases in MS-DRGs 867, 868 and 869. The results of our analysis are shown in the following table. ---------------------------------------------------------------------------------------------------------------- Number of Average length MS-DRG cases of stay Average costs ---------------------------------------------------------------------------------------------------------------- MS-DRG 867--All cases........................................... 2,653 7.5 $14,762 MS-DRG 868--All cases........................................... 2,096 4.4 7,532 MS-DRG 869--All cases........................................... 499 3.3 5,624 ---------------------------------------------------------------------------------------------------------------- We compared the average length of stay and average costs for MS- DRGs 867, 868, and 869 to the average length of stay and average costs for the subsets of cases in MS-DRGs 602 and 603 reported with a principal diagnosis of cellulitis and a secondary diagnosis code of B95.62 or A49.02. We found that the average length of stay for these subsets of cases was shorter and the average costs were lower than those for all cases in MS-DRG 867, but that the average length of stay and average costs were higher than those for all cases in MS-DRG 868 and MS-DRG 869. We stated in the proposed rule that our findings from the analysis of claims data do not support reassigning cellulitis cases reported with ICD-10-CM diagnosis code B95.62 or A49.02 from MS-DRGs 602 and 603 to MS-DRGs 867, 868 and 869. Our clinical advisors noted that when a principal diagnosis of cellulitis is accompanied by a secondary diagnosis of B95.62 or A49.02 in MS-DRGs 602 or 603, the combination of these primary and secondary diagnoses is the reason for the hospitalization, and the level of acuity of these subsets of patients is similar to other patients in MS-DRGs 602 and 603. Therefore, in the proposed rule, we stated that these cases are more clinically aligned with all cases in MS-DRGs 602 and 603. For these reasons, we did not propose to reassign cellulitis cases reported with ICD-10-CM diagnosis code of B95.62 or A49.02 to MS-DRG 867, 868, or 869 for FY 2019. We invited public comments on our proposal to maintain the current MS-DRG assignment for ICD-10-CM codes B95.62 and A49.02 when reported as secondary diagnoses with a principal diagnosis of cellulitis. Comment: One commenter supported CMS' proposal to maintain the current MS-DRG assignment for ICD-10-CM codes B95.62 and A49.02 when reported as secondary diagnoses with a principal diagnosis of cellulitis. Response: We appreciate the commenter's support. After consideration of the public comments we received, we are finalizing our proposal to maintain the current MS-DRG classification for cases reported with ICD-10-CM diagnosis codes B95.62 and A49.02 when reported as secondary diagnoses with a principal diagnosis of cellulitis. 8. MDC 10 (Endocrine, Nutritional and Metabolic Diseases and Disorders): Acute Intermittent Porphyria As discussed in the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20212), we received a request to revise the MS-DRG classification for cases of patients diagnosed with porphyria and reported with ICD-10-CM diagnosis code E80.21 (Acute intermittent (hepatic) porphyria) to recognize the resource requirements in caring for these patients, to ensure appropriate payment for these cases, and to preserve patient access to necessary treatments. Porphyria is defined as a group of rare disorders (``porphyrias'') that interfere with the production of hemoglobin that is needed for red blood cells. While some of these disorders are genetic (inborn) and others are acquired, they all result in the abnormal accumulation of hemoglobin building blocks, called porphyrins, which can be deposited in the tissues where they particularly interfere with the functioning of the nervous system and the skin. Treatment for patients suffering from disorders of porphyrin metabolism consists of an intravenous injection of Panhematin[supreg] (hemin for injection). ICD-10-CM diagnosis code E80.21 is currently assigned to MS-DRG 642 (Inborn and Other Disorders of Metabolism). (We note that this issue has been discussed previously in the FY 2013 IPPS/ LTCH PPS proposed and final rules (77 FR 27904 through 27905 and 77 FR 53311 through 53313, respectively) and the FY 2015 IPPS/LTCH PPS proposed and final rules (79 FR 28016 and 79 FR 49901, respectively)). We analyzed claims data from the September 2017 update of the FY 2017 MedPAR file for cases assigned to MS-DRG 642. Our findings are shown in the following table. ---------------------------------------------------------------------------------------------------------------- Number of Average length MS-DRG 642 cases of stay Average costs ---------------------------------------------------------------------------------------------------------------- MS-DRG 642--All cases........................................... 1,801 4.3 $9,157 MS-DRG 642--Cases reporting diagnosis code E80.21 as principal 183 5.6 19,244 diagnosis...................................................... MS-DRG 642--Cases not reporting diagnosis code E80.21 as 1,618 4.1 8,016 principal diagnosis............................................ ---------------------------------------------------------------------------------------------------------------- As shown in this table, cases reporting diagnosis code E80.21 as the principal diagnosis in MS-DRG 642 had higher average costs and longer average lengths of stay compared to the average costs and lengths of stay for all other cases in MS-DRG 642. To examine the request to reassign cases with ICD-10-CM diagnosis code E80.21 as the principal diagnosis, we analyzed claims data for all cases in MS-DRGs for endocrine disorders, including MS-DRG 643 (Endocrine Disorders with MCC), MS-DRG 644 (Endocrine Disorders with CC), and MS-DRG 645 (Endocrine Disorders without CC/MCC). The results of our analysis are shown in the following table. ---------------------------------------------------------------------------------------------------------------- Number of Average length MS-DRG cases of stay Average costs ---------------------------------------------------------------------------------------------------------------- MS-DRG 643--All cases........................................... 9,337 6.3 $11,268 [[Page 41201]] MS-DRG 644--All cases........................................... 11,306 4.2 7,154 MS-DRG 645--All cases........................................... 4,297 3.2 5,406 ---------------------------------------------------------------------------------------------------------------- The data results showed that the average length of stay for the subset of cases reporting ICD-10-CM diagnosis code E80.21 as the principal diagnosis in MS-DRG 642 is lower than the average length of stay for all cases in MS-DRG 643, but higher than the average length of stay for all cases in MS-DRGs 644 and 645. The average costs for the subset of cases reporting ICD-10-CM diagnosis code E80.21 as the principal diagnosis in MS-DRG 642 are much higher than the average costs for all cases in MS-DRGs 643, 644, and 645. However, after considering these findings in the context of the current MS-DRG structure, we stated in the FY 2019 IPPS/LTCH PPS proposed rule that we were unable to identify an MS-DRG that would more closely parallel these cases with respect to average costs and length of stay that would also be clinically aligned. We further stated that our clinical advisors believe that, in the current MS-DRG structure, the clinical characteristics of patients in these cases are most closely aligned with the clinical characteristics of patients in all cases in MS-DRG 642. Moreover, given the small number of porphyria cases, we do not believe there is justification for creating a new MS-DRG. Basing a new MS-DRG on such a small number of cases could lead to distortions in the relative payment weights for the MS-DRG because several expensive cases could impact the overall relative payment weight. Having larger clinical cohesive groups within an MS-DRG provides greater stability for annual updates to the relative payment weights. In summary, we did not propose to revise the MS-DRG classification for porphyria cases. Comment: Some commenters supported CMS' proposal to maintain porphyria cases in MS-DRG 642. Response: We appreciate the commenters' support. Comment: Other commenters opposed CMS' proposal to not create a new MS-DRG for cases involving ICD-10-CM diagnosis code E80.21. These commenters described significant difficulties encountered by patients with acute porphyria attacks in obtaining Panhematin[supreg] when presenting to an inpatient hospital, which they attribute to the strong financial disincentives faced by facilities to treat these cases on an inpatient basis. The commenters asserted that the inpatient stays required for management of acute porphyria attacks are not clinically similar to inpatient stays for other inborn disorders of metabolism (which comprise the cases assigned to MS-DRG 642). The commenters stated that, based on the lower than expected average cost per case and longer than expected length of stay for acute porphyria attacks, it appears that facilities are frequently not providing Panhematin[supreg] to patients in this condition, and instead attempting to provide symptom relief and transferring patients to an outpatient setting to receive the drug where they can be adequately paid. The commenters stated that this is in contrast to the standard of care for acute porphyria attacks and can result in devastating long-term health consequences. The commenters suggested that CMS consider alternative mechanisms to ensure adequate payment for cases involving rare diseases. In summary, commenters asserted that creating a new MS-DRG would allow more accurate payment for the cases that remain in MS-DRG 642 and facilitate access to the standard of care for patients with acute porphyria attacks. Response: We acknowledge the commenters' concerns. As we have stated in prior rulemaking, it is not appropriate for facilities to deny treatment to beneficiaries needing a specific type of therapy or treatment that involves increased costs. The MS-DRG system is a system of averages and it is expected that across the diagnostic related groups that within certain groups, some cases may demonstrate higher than average costs, while other cases may demonstrate lower than average costs. As discussed in the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20212 through 20213), we recognize the average costs of the small number of porphyria cases are greater than the average costs of the cases in MS-DRG 642 overall. An averaged payment system depends on aggregation of similar cases with a range of costs, and it is therefore usually possible to define subsets with higher values and subsets with lower values. We seek to identify sufficiently large sets of claims data with a resource/cost similarity and clinical similarity in developing diagnostic-related groups rather than smaller subsets of diagnoses. In response to the commenters' assertion that these cases are not clinically similar to other cases within the MS-DRG, our clinical advisors continue to believe that MS-DRG 642 represents the most clinically appropriate placement within the current MS-DRG structure at this time because the clinical characteristics of patients in these cases are most closely aligned with the clinical characteristics of patients in all cases in MS-DRG 642. We are sensitive to the commenters' concerns about access to treatment for beneficiaries who have been diagnosed with this condition. Therefore, as part of our ongoing, comprehensive analysis of the MS-DRGs under ICD-10, we will continue to explore mechanisms through which to address rare diseases and low volume DRGs. However, at this time, for the reasons summarized earlier, we are finalizing our proposal for FY 2019 to maintain the MS-DRG classification for porphyria cases. 9. MDC 11 (Diseases and Disorders of the Kidney and Urinary Tract): Admit for Renal Dialysis As discussed in the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20213 through 20214),we received a request to review the codes assigned to MS-DRG 685 (Admit for Renal Dialysis) to determine if the MS-DRG should be deleted, or if it should remain as a valid MS-DRG. Currently, the ICD-10-CM diagnosis codes shown in the table below are assigned to MS-DRG 685: ------------------------------------------------------------------------ ICD-10-CM code ICD-10-CM code title ------------------------------------------------------------------------ Z49.01.................... Encounter for fitting and adjustment of extracorporeal dialysis catheter. Z49.02.................... Encounter for fitting and adjustment of peritoneal dialysis catheter. Z49.31.................... Encounter for adequacy testing for hemodialysis. [[Page 41202]] Z49.32.................... Encounter for adequacy testing for peritoneal dialysis. ------------------------------------------------------------------------ The requestor stated that, under ICD-9-CM, diagnosis code V56.0 (Encounter for extracorporeal dialysis) was reported as the principal diagnosis to identify patients who were admitted for an encounter for dialysis. However, under ICD-10-CM, there is no comparable code in which to replicate such a diagnosis. The requestor noted that, while patients continued to be admitted under inpatient status (under certain circumstances) for dialysis services, there is no existing ICD-10-CM diagnosis code within the classification that specifically identifies a patient being admitted for an encounter for dialysis services. The requestor also noted that three of the four ICD-10-CM diagnosis codes currently assigned to MS-DRG 685 are on the ``Unacceptable Principal Diagnosis'' edit code list in the Medicare Code Editor (MCE). Therefore, these codes are not allowed to be reported as a principal diagnosis for an inpatient admission. We examined claims data from the September 2017 update of the FY 2017 MedPAR file for cases reporting ICD-10-CM diagnosis codes Z49.01, Z49.02, Z49.31, and Z49.32. Our findings are shown in the following table. Admit for Renal Dialysis Encounter ---------------------------------------------------------------------------------------------------------------- Number of Average length MS-DRG cases of stay Average costs ---------------------------------------------------------------------------------------------------------------- MS-DRG 685--All cases........................................... 78 4 $8,871 MS-DRG 685--Cases reporting ICD-10-CM diagnosis code Z49.01..... 78 4 8,871 MS-DRG 685--Cases reporting ICD-10-CM diagnosis code Z49.02..... 0 0 0 MS-DRG 685--Cases reporting ICD-10-CM diagnosis code Z49.31..... 0 0 0 MS-DRG 685--Cases reporting ICD-10-CM diagnosis code Z49.32..... 0 0 0 ---------------------------------------------------------------------------------------------------------------- As shown in the table above, for MS-DRG 685, there were a total of 78 cases reporting ICD-10-CM diagnosis code Z49.01, with an average length of stay of 4 days and average costs of $8,871. There were no cases reporting ICD-10-CM diagnosis code Z49.02, Z49.31, or Z49.32. Our clinical advisors reviewed the clinical issues, as well as the claims data for MS-DRG 685. Based on their review of the data analysis, our clinical advisors recommended that MS-DRG 685 be deleted and ICD- 10-CM diagnosis codes Z49.01, Z49.02, Z49.31, and Z49.32 be reassigned. Historically, patients were admitted as inpatients to receive hemodialysis services. However, over time, that practice has shifted to outpatient and ambulatory settings. Because of this change in medical practice, we stated in the FY 2019 IPPS/LTCH PPS proposed rule that we did not believe that it was appropriate to maintain a vestigial MS-DRG, particularly due to the fact that the transition to ICD-10 had resulted in three out of four codes that mapped to the MS-DRG being precluded from being used as principal diagnosis codes on the claim. In addition, our clinical advisors believed that reassigning the ICD-10-CM diagnosis codes from MS-DRG 685 to MS-DRGs 698, 699, and 700 (Other Kidney and Urinary Tract Diagnoses with MCC, with CC, and without CC\MCC, respectively) was clinically appropriate because the reassignment would result in an accurate MS-DRG assignment of a specific case or inpatient service and encounter based on acceptable principal diagnosis codes under these MS-DRGs. Therefore, for FY 2019, because there is no existing ICD-10-CM diagnosis code within the classification system that specifically identifies a patient being admitted for an encounter for dialysis services; and three of the four ICD-10-CM diagnosis codes, Z49.02, Z49.31, and Z49.32, currently assigned to MS-DRG 685 are on the Unacceptable Principal Diagnosis edit code list in the MCE, we proposed to reassign ICD-10-CM diagnosis codes Z49.01, Z49.02, Z49.31, and Z49.32 from MS-DRG 685 to MS-DRGs 698, 699, and 700, and to delete MS- DRG 685. Comment: Commenters agreed with the proposal to reassign ICD-10-CM diagnosis codes Z49.01, Z49.02, Z49.31, and Z49.32 from MS-DRG 685 to MS-DRGs 698, 699, and 700, and to delete MS-DRG 685. Response: We thank the commenters for their support. After consideration of the public comments we received, we are finalizing our proposal to delete MS-DRG 685 and reassign ICD-10-CM diagnosis codes Z49.01, Z49.02, Z49.31, and Z49.32 from MS-DRG 685 to MS-DRGs 698, 699, and 700 for FY 2019, without modification. 10. MDC 14 (Pregnancy, Childbirth and the Puerperium) In the FY 2018 IPPS/LTCH PPS proposed rule (82 FR 19834) and final rule (82 FR 38036 through 38037), we noted that the MS-DRG logic involving a vaginal delivery under MDC 14 is technically complex as a result of the requirements that must be met to satisfy assignment to the affected MS-DRGs. As a result, we solicited public comments on further refinement to the following four MS-DRGs related to vaginal delivery: MS-DRG 767 (Vaginal Delivery with Sterilization and/or D&C); MS-DRG 768 (Vaginal Delivery with O.R. Procedure Except Sterilization and/or D&C); MS-DRG 774 (Vaginal Delivery with Complicating Diagnosis); and MS-DRG 775 (Vaginal Delivery without Complicating Diagnosis). In addition, we sought public comments on further refinements to the conditions defined as a complicating diagnosis in MS-DRG 774 and MS-DRG 781 (Other Antepartum Diagnoses with Medical Complications). We indicated that we would review public comments received in response to the solicitation as we continued to evaluate these MS-DRGs under MDC 14 and, if warranted, we would propose refinements for FY 2019. Commenters were instructed to direct comments for consideration to the CMS MS-DRG Classification Change Request Mailbox located at [email protected] by November 1, 2017. [[Page 41203]] In response to our solicitation for public comments on the MS-DRGs related to vaginal delivery, one commenter recommended that CMS convene a workgroup that would include hospital staff and physicians to systematically review the MDC 14 MS-DRGs and to identify which conditions should appropriately be considered complicating diagnoses. As an interim step, this commenter recommended that CMS consider the following suggestions as a result of its own evaluation of MS-DRGs 767, 774 and 775. For MS-DRG 767, the commenter recommended that the following ICD- 10-CM diagnosis codes and ICD-10-PCS procedure code be removed from the GROUPER logic and provided the rationale for why the commenter suggested removing each code.

For instance, the commenter noted that the GROUPER logic code lists appear redundant with several of the same codes listed for different MS-DRGs and that the GROUPER logic code list for a vaginal delivery in MS-DRG 774 is comprised of diagnosis codes while the GROUPER logic code list for a vaginal delivery in MS-DRG 775 is comprised of procedure codes. The commenter also noted that several of the ICD-10-CM diagnosis codes shown in the table below that became effective with discharges on and after October 1, 2016 (FY 2017) or October 1, 2017 (FY 2018) appear to be missing from the GROUPER logic code lists for MS-DRGs 781 and 774. ------------------------------------------------------------------------ ICD-10-CM code Code description ------------------------------------------------------------------------ O11.4.....................

We note that it was not clear which list of procedure codes the commenter was specifically referencing. The commenter did not provide a list of any procedure codes for CMS to review or reference a specific MS-DRG in its comment. Another commenter expressed concern that ICD-10-PCS procedure codes 10D17Z9 (Manual extraction of products of conception, retained, via natural or artificial opening) and 10D18Z9 (Manual extraction of products of conception, retained, via natural or artificial opening endoscopic) are not assigned to the appropriate MS-DRG. ICD-10-PCS procedure codes 10D17Z9 and 10D18Z9 describe the manual removal of a retained placenta and are currently assigned to MS-DRG 767 (Vaginal Delivery with Sterilization and/or D&C). According to the commenter, a patient that has a vaginal delivery with manual removal of a retained placenta is not having a sterilization or D&C procedure. The commenter noted that, under ICD-9-CM, a vaginal delivery with manual removal of retained placenta grouped to MS-DRG 774 (Vaginal Delivery with Complicating Diagnosis) or MS-DRG 775 (Vaginal Delivery without Complicating Diagnosis). The commenter suggested CMS review these procedure codes for appropriate MS-DRG assignment under the ICD-10 MS- DRGs. In the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20217), we thanked the commenters and stated that we appreciated the recommendations and suggestions provided in response to our solicitation for comments on the GROUPER logic for the MS-DRGs involving a vaginal delivery or complicating diagnosis under MDC 14. With regard to the commenter who recommended that we convene a workgroup that would include hospital staff and physicians to systematically review the MDC 14 MS-DRGs and to identify which conditions should appropriately be considered complicating diagnoses, we noted that we formed an internal workgroup comprised of clinical advisors that included physicians, coding specialists, and other IPPS policy staff that assisted in our review of the GROUPER logic for a vaginal delivery and complicating diagnoses. We indicated that we also received clinical input from 3M/Health Information Systems (HIS) staff, which, under contract with CMS, is responsible for updating and maintaining the GROUPER program. We note that our analysis involved other MS-DRGs under MDC 14, in addition to those for which we specifically solicited public comments. As one of the other commenters correctly pointed out, there is redundancy, with several of the same codes listed for different MS-DRGs. Below we provide a summary of our internal analysis with responses to the commenters' recommendations and suggestions incorporated into the applicable sections. We referred readers to the ICD-10 MS-DRG Version 35 Definitions Manual located via the internet on the CMS website at: https://www.cms.gov/Medicare/ Medicare-Fee-for-Service-Payment/ [[Page 41206]] AcuteInpatientPPS/FY2018-IPPS-Final-Rule-Home-Page-Items/FY2018-IPPS- Final-Rule-Data- Files.html?DLPage=1&DLEntries=10&DLSort=0&DLSortDir=ascending for documentation of the GROUPER logic associated with the MDC 14 MS-DRGs to assist in the review of our discussion that follows. We started our evaluation of the GROUPER logic for the MS-DRGs under MDC 14 by first reviewing the current concepts that exist. For example, there are ``groups'' for cesarean section procedures, vaginal delivery procedures, and abortions. There also are groups where no delivery occurs, and lastly, there are groups for after the delivery occurs, or the ``postpartum'' period. These groups are then further subdivided based on the presence or absence of complicating conditions or the presence of another procedure. We examined how we could simplify some of the older, complex GROUPER logic and remain consistent with the structure of other ICD-10 MS-DRGs. We identified the following MS-DRGs for closer review, in addition to MS-DRG 767, MS-DRG 768, MS-DRG 774, MS-DRG 775 and MS-DRG 781. ------------------------------------------------------------------------ MS-DRG Description ------------------------------------------------------------------------ MS-DRG 765................ Cesarean Section with CC/MCC. MS-DRG 766................ Cesarean Section without CC/MCC. MS-DRG 769................ Postpartum and Post Abortion Diagnoses with O.R. Procedure. MS-DRG 770................ Abortion with D&C, Aspiration Curettage or Hysterotomy. MS-DRG 776................ Postpartum and Post Abortion Diagnoses without O.R. Procedure. MS-DRG 777................ Ectopic Pregnancy. MS-DRG 778................ Threatened Abortion. MS-DRG 779................ Abortion without D&C. MS-DRG 780................ False Labor. MS-DRG 782................ Other Antepartum Diagnoses without Medical Complications. ------------------------------------------------------------------------ The first issue we reviewed was the GROUPER logic for complicating conditions (MS-DRGs 774 and 781). Because one of the main objectives in our transition to the MS-DRGs was to better recognize the severity of illness of a patient, we believed we could structure the vaginal delivery and other MDC 14 MS-DRGs in a similar way. Therefore, we began working with the concept of vaginal delivery ``with MCC, with CC and without CC/MCC'' to replace the older, ``complicating conditions'' logic. Next, we compared the additional GROUPER logic that exists between the vaginal delivery and the cesarean section MS-DRGs (MS-DRGs 765, 766, 767, 774, and 775). Currently, the vaginal delivery MS-DRGs take into account a sterilization procedure; however, the cesarean section MS-DRGs do not. Because a patient can have a sterilization procedure performed along with a cesarean section procedure, we adopted a working concept of ``cesarean section with and without sterilization with MCC, with CC and without CC/MCC'', as well as ``vaginal delivery with and without sterilization with MCC, with CC and without CC/MCC''. We then reviewed the GROUPER logic for the MS-DRGs involving abortion and where no delivery occurs (MS-DRGs 770, 777, 778, 779, 780, and 782). We believed that we could consolidate the groups in which no delivery occurs. Finally, we considered the GROUPER logic for the MS-DRGs related to the postpartum period (MS-DRGs 769 and 776) and determined that the structure of these MS-DRGs did not appear to require modification. After we established those initial working concepts for the MS-DRGs discussed above, we examined the list of the ICD-10-PCS procedure codes that comprise the sterilization procedure GROUPER logic for the vaginal delivery MS-DRG 767. We identified the two manual extraction of placenta codes that the commenter had brought to our attention (ICD-10- PCS codes 10D17Z9 and 10D18Z9). We also identified two additional procedure codes, ICD-10-PCS codes 10D17ZZ (Extraction of products of conception, retained, via natural or artificial opening) and 10D18ZZ (Extraction of products of conception, retained, via natural or artificial opening endoscopic) in the list that are not sterilization procedures. Two of the four procedure codes describe manual extraction (removal) of retained placenta and the other two procedure codes describe dilation and curettage procedures. We then identified four more procedure codes in the list that do not describe sterilization procedures. ICD-10-PCS procedure codes 0UDB7ZX (Extraction of endometrium, via natural or artificial opening, diagnostic), 0UDB7ZZ (Extraction of endometrium, via natural or artificial opening), 0UDB8ZX (Extraction of endometrium, via natural or artificial opening endoscopic, diagnostic), and 0UDB8ZZ (Extraction of endometrium, via natural or artificial opening endoscopic) describe dilation and curettage procedures that can be performed for diagnostic or therapeutic purposes. We stated in the proposed rule that we believe that these ICD-10-PCS procedure codes would be more appropriately assigned to MDC 13 (Diseases and Disorders of the Female Reproductive System) in MS-DRGs 744 and 745 (D&C, Conization, Laparaoscopy and Tubal Interruption with and without CC/MCC, respectively) and, therefore, removed them from our working list of sterilization and/or D&C procedures. Because the GROUPER logic for MS-DRG 767 includes both sterilization and/or D&C, we agreed that all the other procedure codes currently included under that logic list of sterilization procedures should remain, with the exception of the two identified by the commenter. Therefore, in the proposed rule, we stated we agreed with the commenter that the manual extraction of retained placenta procedure codes should be reassigned to a more clinically appropriate vaginal delivery MS-DRG because they are not describing sterilization procedures. Our attention then turned to other MDC 14 GROUPER logic code lists starting with the ``CC for C-section'' list under MS-DRGs 765 and 766 (Cesarean Section with and without CC/MCC, respectively). As noted in the proposed rule and earlier in this section, in conducting our review, we considered how we could utilize the severity level concept (with MCC, with CC, and without CC/MCC) where applicable. Consistent with this approach, we removed the ``CC for C-section'' logic from these MS-DRGs as part of our working concept and efforts to refine MDC 14. We determined it would be less complicated to simply allow the existing ICD-10 MS-DRG CC and MCC [[Page 41207]] code list logic to apply for these MS-DRGs. Next, we reviewed the logic code lists for ``Malpresentation'' and ``Twins'' and concluded that this logic was not necessary for the cesarean section MS-DRGs because these are describing antepartum conditions and it is the procedure of the cesarean section that determines whether or not a patient would be classified to these MS-DRGs. Therefore, those code lists were also removed for purposes of our working concept. With regard to the ``Operating Room Procedure'' code list, we stated in the proposed rule that we agreed there should be no changes. However, we noted that the title to ICD-10-PCS procedure code 10D00Z0 (Extraction of products of conception, classical, open approach) is being revised, effective October 1, 2018, to replace the term ``classical'' with ``high'' and ICD-10-PCS procedure code 10D00Z1 (Extraction of products of conception, low cervical, open approach) is being revised to replace the term ``low cervical'' to ``low''. These revisions are also shown in Table 6F--Revised Procedure Code Titles associated with the proposed rule and this final rule available via the internet on the CMS website at: http://www.cms.gov/Medicare/Medicare-Fee-for-Service-Payment/AcuteInpatientPPS/index.html. Next, we reviewed the ``Delivery Procedure'' and ``Delivery Outcome'' GROUPER logic code lists for the vaginal delivery MS-DRGs 767, 768, 774, and 775. We identified ICD-10-PCS procedure code 10A0726 (Abortion of products of conception, vacuum, via natural or artificial opening) and ICD-10-PCS procedure code 10S07ZZ (Reposition products of conception, via natural or artificial opening) under the ``Delivery Procedure'' code list as procedure codes that should not be included because ICD-10-PCS procedure code 10A07Z6 describes an abortion procedure and ICD-10-PCS procedure code 10S07ZZ describes repositioning of the fetus and does not indicate a delivery took place. We also noted that, as described in the proposed rule and earlier in this discussion, a commenter recommended that ICD-10-PCS procedure code 10A07Z6 be removed from the GROUPER logic specifically for MS-DRGs 767 and 775. Therefore, we removed these two procedure codes from the logic code list for ``Delivery Procedure'' in MS-DRGs 767, 768, 774, and 775. We stated in the proposed rule that we agreed with the commenter that ICD- 10-PCS procedure code 10A07Z6 would be more appropriately assigned to one of the Abortion MS-DRGs. For the remaining procedures currently included in the ``Delivery Procedure'' code list we considered which procedures would be expected to be performed during the course of a standard, uncomplicated delivery episode versus those that would reasonably be expected to require additional resources outside of the delivery room. The list of procedure codes we reviewed is shown in the following table. ------------------------------------------------------------------------ ICD-10-PCS code Code description ------------------------------------------------------------------------ 0DQP7ZZ................... Repair rectum, via natural or artificial opening. 0DQQ0ZZ................... Repair anus, open approach. 0DQQ3ZZ................... Repair anus, percutaneous approach. 0DQQ4ZZ................... Repair anus, percutaneous endoscopic approach. 0DQQ7ZZ................... Repair anus, via natural or artificial opening. 0DQQ8ZZ................... Repair anus, via natural or artificial opening endoscopic. 0DQR0ZZ................... Repair anal sphincter, open approach. 0DQR3ZZ................... Repair anal sphincter, percutaneous approach. 0DQR4ZZ................... Repair anal sphincter, percutaneous endoscopic approach. ------------------------------------------------------------------------ While we acknowledged that these procedures may be performed to treat obstetrical lacerations as discussed in prior rulemaking (81 FR 56853), we stated that we also believe that these procedures would reasonably be expected to require a separate operative episode and would not be performed immediately at the time of the delivery. Therefore, we removed those procedure codes describing repair of the rectum, anus, and anal sphincter shown in the table above from our working concept list of procedures to consider for a vaginal delivery. Our review of the list of diagnosis codes for the ``Delivery Outcome'' as a secondary diagnosis did not prompt any changes. We stated in the proposed rule we agreed that the current list of diagnosis codes continues to appear appropriate for describing the outcome of a delivery. As the purpose of our analysis and this review was to clarify what constitutes a vaginal delivery to satisfy the ICD-10 MS-DRG logic for the vaginal delivery MS-DRGs, we believed it was appropriate to expect that a procedure code describing the vaginal delivery or extraction of ``products of conception'' procedure and a diagnosis code describing the delivery outcome should be reported on every claim in which a vaginal delivery occurs. This is also consistent with Section I.C.15.b.5 of the ICD-10-CM Official Guidelines for Coding and Reporting, which states ``A code from category Z37, Outcome of delivery, should be included on every maternal record when a delivery has occurred. These codes are not to be used on subsequent records or on the newborn record.'' Therefore, we adopted the working concept that, regardless of the principal diagnosis, if there is a procedure code describing the vaginal delivery or extraction of ``products of conception'' procedure and a diagnosis code describing the delivery outcome, this logic would result in assignment to a vaginal delivery MS-DRG. In the proposed rule, we noted that, as a result of this working concept, there would no longer be a need to maintain the ``third condition'' list under MS-DRG 774. In addition, as noted in the proposed rule and earlier in this discussion, because we were working with the concept of vaginal delivery ``with MCC, with CC, and without CC/MCC'' to replace the older, ``complicating conditions'' logic, there would no longer be a need to maintain the ``second condition'' list of complicating diagnosis under MS-DRG 774. We then reviewed the GROUPER logic code list of ``Or Other O.R. procedures'' (MS-DRG 768) to determine if any changes to these lists were warranted. Similar to our analysis of the procedures listed under the ``Delivery Procedure'' logic code list, our examination of the procedures currently described in the ``Or Other O.R. procedures'' procedure code list also considered which procedures would be expected to be [[Page 41208]] performed during the course of a standard, uncomplicated delivery episode versus those that would reasonably be expected to require additional resources outside of the delivery room. Our analysis of all the procedures resulted in the working concept to allow all O.R. procedures to be applicable for assignment to MS-DRG 768, with the exception of the procedure codes for sterilization and/or D&C and ICD- 10-PCS procedure codes 0KQM0ZZ (Repair perineum muscle, open approach) and 0UJM0ZZ (Inspection of vulva, open approach), which we determined would be reasonably expected to be performed during a standard delivery episode and, therefore, assigned to MS-DRG 774 or MS-DRG 775. We also noted that, this working concept for MS-DRG 768 would eliminate vaginal delivery cases with an O.R. procedure grouping to the unrelated MS-DRGs because all O.R. procedures would be included in the GROUPER logic procedure code list for ``Or Other O.R. Procedures''. The next set of MS-DRGs we examined more closely included MS-DRGs 777, 778, 780, 781, and 782. We believed that, because the conditions in these MS-DRGs are all describing antepartum related conditions, we could group the conditions together clinically. Diagnoses described as occurring during pregnancy and diagnoses specifying a trimester or maternal care in the absence of a delivery procedure reported were considered antepartum conditions. We also believed we could better classify these groups of patients based on the presence or absence of a procedure. Therefore, we worked with the concept of ``antepartum diagnoses with and without O.R. procedure''. As noted in the proposed rule and earlier in the discussion, we adopted a working concept of ``cesarean section with and without sterilization with MCC, with CC, and without CC/MCC.'' This concept is illustrated in the following table and includes our suggested modifications. Suggested Modifications to MS-DRGs for MDC 14 [Pregnancy, childbirth and the puerperium] ------------------------------------------------------------------------ ------------------------------------------------------------------------- DELETE 2 MS-DRGs: MS-DRG 765 (Cesarean Section with CC/MCC). MS-DRG 766 (Cesarean Section without CC/MCC). CREATE 6 MS-DRGs: MS-DRG XXX (Cesarean Section with Sterilization with MCC). MS-DRG XXX (Cesarean Section with Sterilization with CC).

MS-DRG XXX (Cesarean Section without Sterilization without CC/MCC). ------------------------------------------------------------------------ As shown in the table, we suggested deleting MS-DRGs 765 and 766. We also suggested creating 6 new MS-DRGs that are subdivided by a 3-way severity level split that includes ``with Sterilization'' and ``without Sterilization''. We also adopted a working concept of ``vaginal delivery with and without sterilization with MCC, with CC, and without CC/MCC''. This concept is illustrated in the following table and includes our suggested modifications. Suggested Modifications to MS-DRGs for MDC 14 [Pregnancy, childbirth and the puerperium] ------------------------------------------------------------------------ ------------------------------------------------------------------------- DELETE 3 MS-DRGs: MS-DRG 767 (Vaginal Delivery with Sterilization and/or D&C).

We also suggested creating 6 new MS-DRGs that are subdivided by a 3-way severity level split that includes ``with Sterilization/D&C'' and ``without Sterilization/D&C''. In addition, as indicated above, we believed that we could consolidate the groups in which no delivery occurs. In the proposed rule, we stated we believe that consolidating MS-DRGs where clinically coherent conditions exist is consistent with our approach to MS-DRG reclassification and our continued refinement efforts. This concept is illustrated in the following table and includes our suggested modifications. Suggested Modifications to MS-DRGs for MDC 14 [Pregnancy, childbirth and the puerperium] ------------------------------------------------------------------------ ------------------------------------------------------------------------- DELETE 5 MS-DRGs: MS-DRG 777 (Ectopic Pregnancy).

MS-DRG XXX (Other Antepartum Diagnoses without O.R. Procedure with CC). MS-DRG XXX (Other Antepartum Diagnoses without O.R.

We also suggested creating 6 new MS-DRGs that are subdivided by a 3-way severity level split that includes ``with O.R. Procedure'' and ``without O.R. Procedure''. Once we established each of these fundamental concepts from a clinical perspective, we were able to analyze the data to determine if our initial suggested modifications were supported. To analyze our suggested modifications for the cesarean section and vaginal delivery MS-DRGs, we examined the claims data from the September 2017 update of the FY 2017 MedPAR file for MS-DRGs 765, 766, 767, 768, 774, and 775.

Lastly, for MS-DRG 775, there were a total of 4,676 cases, with an average length of stay of 2.4 days and average costs of $4,769. To compare and analyze the impact of our suggested modifications, we ran a simulation using the Version 35 ICD-10 MS-DRG GROUPER. The following table reflects our findings for the suggested Cesarean Section MS-DRGs with a 3-way severity level split.

There were a total of 4,105 cases for the vaginal delivery without sterilization/D&C without CC/MCC group, with an average length of stay of 2.3 days and average costs of $4,601. We then reviewed the claims data from the September 2017 update of the FY 2017 MedPAR file for MS-DRGs 777, 778, 780, 781, and 782. Our findings are shown in the following table. [[Page 41210]] MS-DRGs for MDC 14 Pregnancy, Childbirth and the Puerperium ---------------------------------------------------------------------------------------------------------------- Number of Average length MS-DRG cases of stay Average costs ---------------------------------------------------------------------------------------------------------------- MS-DRG 777 (Ectopic Pregnancy)--All cases....................... 72 1.9 $7,149 MS-DRG 778 (Threatened Abortion)--All cases..................... 205 2.7 4,001 MS-DRG 780 (False Labor)--All cases............................. 41 2.1 3,045 MS-DRG 781 (Other Antepartum Diagnoses with Medical 2,333 3.7 5,817 Complications)--All cases......................................

For MS-DRG 778, there were a total of 205 cases, with an average length of stay of 2.7 days and average costs of $4,001. For MS- DRG 780, there were a total of 41 cases, with an average length of stay of 2.1 days and average costs of $3,045.

Lastly, for MS-DRG 782, there were a total of 70 cases, with an average length of stay of 2.1 days and average costs of $3,381. To compare and analyze the impact of deleting those 5 MS-DRGs and creating 6 new MS-DRGs, we ran a simulation using the Version 35 ICD-10 MS-DRG GROUPER. Our findings below represent what we found and would expect under the suggested modifications. The following table reflects the MS-DRGs for the suggested Other Antepartum Diagnoses MS-DRGs with a 3-way severity level split. Suggested MS-DRGs for Other Antepartum Diagnoses ---------------------------------------------------------------------------------------------------------------- Number of Average length MS-DRG cases of stay Average costs ---------------------------------------------------------------------------------------------------------------- MS-DRG 817 (Other Antepartum Diagnoses with O.R.

Procedure 855 2.7 3,843 without CC/MCC)................................................ ---------------------------------------------------------------------------------------------------------------- Our analysis of claims data from the September 2017 update of the FY 2017 MedPAR file recognized that when the criteria to create subgroups were applied for the 3-way severity level splits for the suggested MS-DRGs, those criteria were not met in all instances. For example, the criteria that there are at least 500 cases in the MCC or CC group was not met for the suggested Vaginal Delivery with Sterilization/D&C 3-way severity level split or the suggested Other Antepartum Diagnoses with O.R. Procedure 3-way severity level split. However, as we have noted in prior rulemaking (72 FR 47152), we cannot adopt the same approach to refine the maternity and newborn MS- DRGs because of the extremely low volume of Medicare patients there are in these DRGs. While there is not a high volume of these cases represented in the Medicare data, and while we generally advise that other payers should develop MS-DRGs to address the needs of their patients, we believe that our suggested 3-way severity level splits would address the complexity of the current MDC 14 GROUPER logic for a vaginal delivery and takes into account the new and different clinical concepts that exist under ICD-10 for this subset of patients while also maintaining the existing MS-DRG structure for identifying severity of illness, utilization of resources and complexity of service. However, as an alternative option, we also performed analysis for a 2-way severity level split for the suggested MS-DRGs. Our findings are shown in the following tables. Suggested MS-DRGs for Cesarean Section ---------------------------------------------------------------------------------------------------------------- Number of Average length MS-DRG cases of stay Average costs ---------------------------------------------------------------------------------------------------------------- MS-DRG XXX (Cesarean Section with Sterilization with CC/MCC).... 689 4.7 $9,317 MS-DRG XXX (Cesarean Section with Sterilization without CC/MCC). 475 3.0 6,259 MS-DRG XXX (Cesarean Section without Sterilization with MCC).... 2,594 4.7 8,951 MS-DRG XXX (Cesarean Section without Sterilization without CC/ 1,710 3.3 6,663 MCC)........................................................... ---------------------------------------------------------------------------------------------------------------- Suggested MS-DRGs for Vaginal Delivery ---------------------------------------------------------------------------------------------------------------- Number of Average length MS-DRG cases of stay Average costs ---------------------------------------------------------------------------------------------------------------- MS-DRG XXX (Vaginal Delivery with Sterilization/D&C with CC/MCC) 88 3.6 $7,586 MS-DRG XXX (Vaginal Delivery with Sterilization/D&C without CC/ 126 2.3 6,697 MCC)...........................................................

Procedure 855 2.7 3,843 without CC/MCC)................................................ ---------------------------------------------------------------------------------------------------------------- Similar to the analysis performed for the 3-way severity level split, we acknowledged that when the criteria to create subgroups was applied for the alternative 2-way severity level splits for the suggested MS-DRGs, those criteria were not met in all instances. For example, the suggested Vaginal Delivery with Sterilization/D&C and the Other Antepartum Diagnoses with O.R. Procedure alternative option 2-way severity level splits did not meet the criteria for 500 or more cases in the MCC or CC group. Based on our review, which included support from our clinical advisors, and the analysis of claims data described above, in the FY 2019 IPPS/LTCH PPS proposed rule, we proposed the deletion of 10 MS- DRGs and the creation of 18 new MS-DRGs (as shown below). This proposal was based on the approach described above, which involves consolidating specific conditions and concepts into the structure of existing logic and making additional modifications, such as adding severity levels, as part of our refinement efforts for the ICD-10 MS-DRGs. We indicated in the proposed rule that our proposals are intended to address the vaginal delivery ``complicating diagnosis'' logic and antepartum diagnoses with ``medical complications'' logic with the proposed addition of the existing and familiar severity level concept (with MCC, with CC, and without CC/MCC) to the MDC 14 MS-DRGs to provide the ability to distinguish the varying resource requirements for this subset of patients and allow the opportunity to make more meaningful comparisons with regard to severity across the MS-DRGs. We stated that our proposals, as set forth below, would also simplify the vaginal delivery procedure logic that we identified and commenters acknowledged as technically complex by eliminating the extensive diagnosis and procedure code lists for several conditions that must be met for assignment to the vaginal delivery MS-DRGs. We stated that our proposals also are intended to respond to issues identified and brought to our attention through public comments for consideration in updating the GROUPER logic code lists in MDC 14. Specifically, we proposed to delete the following 10 MS-DRGs under MDC 14: MS-DRG 765 (Cesarean Section with CC/MCC); MS-DRG 766 (Cesarean Section without CC/MCC); MS-DRG 767 (Vaginal Delivery with Sterilization and/or D&C); MS-DRG 774 (Vaginal Delivery with Complicating Diagnosis); MS-DRG 775 (Vaginal Delivery without Complicating Diagnosis); MS-DRG 777 (Ectopic Pregnancy); MS-DRG 778 (Threatened Abortion); MS-DRG 780 (False Labor); MS-DRG 781 (Other Antepartum Diagnoses with Medical Complications); and MS-DRG 782 (Other Antepartum Diagnoses without Medical Complications). We proposed to create the following new 18 MS-DRGs under MDC 14: Proposed new MS-DRG 783 (Cesarean Section with Sterilization with MCC); Proposed new MS-DRG 784 (Cesarean Section with Sterilization with CC); Proposed new MS-DRG 785 (Cesarean Section with Sterilization without CC/MCC); Proposed new MS-DRG 786 (Cesarean Section without Sterilization with MCC); Proposed new MS-DRG 787 (Cesarean Section without Sterilization with CC); Proposed new MS-DRG 788 Cesarean Section without Sterilization without CC/MCC); Proposed new MS-DRG 796 (Vaginal Delivery with Sterilization/D&C with MCC); Proposed new MS-DRG 797 (Vaginal Delivery with Sterilization/D&C with CC); Proposed new MS-DRG 798 (Vaginal Delivery with Sterilization/D&C without CC/MCC); Proposed new MS-DRG 805 (Vaginal Delivery without Sterilization/D&C with MCC); Proposed new MS-DRG 806 (Vaginal Delivery without Sterilization/D&C with CC); Proposed new MS-DRG 807 (Vaginal Delivery without Sterilization/D&C without CC/MCC); Proposed new MS-DRG 817 (Other Antepartum Diagnoses with O.R. Procedure with MCC); Proposed new MS-DRG 818 (Other Antepartum Diagnoses with O.R. Procedure with CC); Proposed new MS-DRG 819 (Other Antepartum Diagnoses with O.R. Procedure without CC/MCC); Proposed new MS-DRG 831 (Other Antepartum Diagnoses without O.R. Procedure with MCC); Proposed new MS-DRG 832 (Other Antepartum Diagnoses without O.R. Procedure with CC); and Proposed new MS-DRG 833 (Other Antepartum Diagnoses without O.R. Procedure without CC/MCC). The diagrams below illustrate how the proposed MS-DRG logic for MDC 14 would function. The first diagram (Diagram 1.) begins by asking if there is a principal diagnosis from MDC 14. If no, the GROUPER logic directs the case to the appropriate MDC based on the principal diagnosis reported. Next, the logic asks if there is a cesarean section procedure reported on the claim. If yes, the logic asks if there was a sterilization procedure reported on the claim. If yes, the logic assigns the case to one of the proposed new MS-DRGs 783, 784, or 785. If no, the logic assigns the case to one of the proposed new MS-DRGs 786, 787, or 788. If there was not a cesarean section procedure reported on the claim, the logic asks if there was a vaginal delivery procedure reported on the claim. If yes, the logic asks if there was another O.R. procedure other than sterilization, D&C, delivery procedure or a delivery inclusive O.R. procedure. If yes, the logic assigns the case to existing MS-DRG 768. If no, the logic asks if there was a sterilization and/or D&C reported on the claim. If yes, the logic assigns the case to one of the proposed new MS-DRGs 796, 797, or 798. If no, the logic assigns the case to one of the proposed new MS-DRGs 805, 806, or 807. If there was not a vaginal delivery procedure reported on the claim, the GROUPER logic directs you to the other [[Page 41212]] non-delivery MS-DRGs as shown in Diagram 2. BILLING CODE 4120-01-P [GRAPHIC] [TIFF OMITTED] TR17AU18.000 The logic for Diagram 2. begins by asking if there is a principal diagnosis of abortion reported on the claim. If yes, the logic then asks if there was a D&C, aspiration curettage or hysterotomy procedure reported on the claim. If yes, the logic assigns the case to existing MS-DRG 770. If no, the logic assigns the case to existing MS-DRG 779. If there was not a principal diagnosis of abortion reported on the claim, the logic asks if there was a principal diagnosis of an antepartum condition reported on the claim. If yes, the logic then asks if there was an O.R. procedure reported on the claim. If yes, the logic assigns the case to one of the proposed new MS-DRGs 817, 818, or 819. If no, the logic assigns the case to one of the proposed new MS-DRGs 831, 832, or 833. If there was not a principal diagnosis of an antepartum condition reported on the claim, the logic asks if there was a principal diagnosis of a postpartum condition reported on the claim. If yes, the logic then asks if there was an O.R. procedure reported on the claim. If yes, the logic assigns the case to existing MS-DRG 769. If no, the logic assigns the case to existing MS-DRG 776. If there was not a principal diagnosis of a postpartum condition reported on the claim, the logic identifies that there was a principal diagnosis describing childbirth, delivery or an intrapartum condition reported on the claim without [[Page 41213]] any other procedures, and assigns the case to existing MS-DRG 998 (Principal Diagnosis Invalid as Discharge Diagnosis). To assist in detecting coding and MS-DRG assignment errors for MS- DRG 998 that could result when a provider does not report the procedure code for either a cesarean section or a vaginal delivery along with an outcome of delivery diagnosis code, as discussed in section II.F.13.d., we proposed to add a new Questionable Obstetric Admission edit under the MCE. We invited public comments on this proposed MCE edit and we also invited public comments on the need for any additional MCE considerations with regard to the proposed changes for the MDC 14 MS- DRGs. [GRAPHIC] [TIFF OMITTED] TR17AU18.001 BILLING CODE 4120-01-C We referred readers to Tables 6P.1h. through 6P.1k. associated with the proposed rule for the lists of the diagnosis and procedure codes that we proposed to assign to the GROUPER logic for the proposed new MS-DRGs and the existing MS-DRGs under MDC 14. We invited public comments on our proposed list of diagnosis codes, which also addresses the list of diagnosis codes that a commenter identified as missing from the GROUPER logic. We noted that, as a result of our proposed GROUPER logic changes to the vaginal delivery MS-DRGs, which would only take into account the procedure codes for a vaginal delivery and the outcome of delivery secondary diagnosis codes, there is no longer a need to maintain a specific principal diagnosis logic list for those MS-DRGs. Therefore, while we [[Page 41214]] appreciate the detailed suggestions and rationale submitted by the commenter for why specific diagnosis codes should be removed from the vaginal delivery principal diagnosis logic as displayed earlier in this discussion, we proposed to remove that logic. We invited public comments on this proposal, as well as our proposed list of procedure codes for the proposed revised MDC 14 MS-DRG logic, which would require a procedure code for case assignment. We also invited public comments on the proposed deletion of the 10 MS-DRGs and the proposed creation of 18 new MS-DRGs with a 3-way severity level split listed above in this section, as well as on the potential alternative new MS-DRGs using a 2- way severity level split as also presented above. Comment: Commenters agreed with CMS' proposal to restructure the MS-DRGs within MDC 14. A few commenters commended CMS on the proposed new structure and GROUPER logic for these MS-DRGs, and believed that the new structure and logic is clearer and clinically appropriate. Another commenter agreed with the proposed new GROUPER logic for MDC 14 for deliveries with the 3-way severity level splits. The commenters anticipated that the new structure and logic will provide more clarity than the current structure. Response: We appreciate the commenters' support. We agree the proposed new structure and GROUPER logic of the MS-DRGs under MDC 14 will provide more clarity than the current structure and logic. Comment: Another commenter stated that all of the diagnoses currently assigned to MS-DRG 774 (Vaginal Delivery with Complicating Diagnosis) in the GROUPER logic, along with some of the diagnoses that were noted to appear to be missing from the GROUPER logic (83 FR 20216 through 20217), should be added to the Principal Diagnosis Is Its Own CC Or MCC logic for the proposed new vaginal delivery MS-DRGs 796 (Vaginal Delivery with Sterilization/D&C with MCC), 797 (Vaginal Delivery with Sterilization/D&C with CC), 798 (Vaginal Delivery with Sterilization/D&C without CC/MCC), 805 (Vaginal Delivery without Sterilization/D&C with MCC), 806 (Vaginal Delivery without Sterilization/D&C with CC), and 807 (Vaginal Delivery without Sterilization/D&C without CC/MCC). The commenter provided the following list of diagnosis codes that were noted to appear to be missing from the GROUPER logic, and requested CMS consider adding these diagnosis codes to the Principal Diagnosis Is Its Own CC Or MCC Lists. The commenter believed that the current GROUPER logic for MS-DRG 774 includes diagnoses that could change the MS-DRG assignment of a case from MS-DRG 775 to MS-DRG 774 based on the principal diagnosis. The commenter further expressed concern that these same diagnoses may group to the proposed new MS-DRGs 798 or 807 (without CC/MCC) under the proposed new structure and GROUPER logic for the vaginal delivery MS- DRGs. ------------------------------------------------------------------------ ICD-10-CM code Code description ------------------------------------------------------------------------ O11.5.....................

For the reasons stated in section II.F.15.c. of the preamble of this final rule, we are finalizing that proposal, and therefore this logic will no longer apply for FY 2019. We refer readers to section II.F.15.c. of the preamble of this final rule for further discussion of the specific proposal, including summaries of the public comments we received and our responses and our statement of final policy. With regard to the commenter's concern that the diagnosis codes listed above appear to be missing from the GROUPER logic, we note that, currently, all of the diagnoses codes are included in the MDC 14 Assignment of Diagnosis Codes List. The diagnosis codes that include the terminology ``complicating the puerperium'' are listed under the ``Second Condition--Principal or Secondary Diagnosis'' code list in the diagnosis code logic for MS-DRG 774, and the diagnosis codes that include the terminology ``complicating childbirth'' are listed under the ``Principal Diagnosis'' code list for the diagnosis code logic for MS-DRG 781 (Other Antepartum Diagnoses with Medical Complications). We acknowledge that the diagnosis codes that include the [[Page 41215]] terminology ``complicating childbirth'' that the commenter referenced were inadvertently omitted, and are not listed in the ICD-10 MS-DRG Definitions Manual Version 35 under the diagnosis code logic list for MS-DRG 774 (or for MS-DRGs 767 (Vaginal Delivery with Sterilization and/or D&C) and 768 (Vaginal Delivery with O.R. Procedure Except Sterilization and/or D&C)). However, if one of those diagnosis codes is reported with a procedure code from the vaginal delivery code list, the ICD-10 MS-DRG GROUPER Version 35 accurately groups the case to a vaginal delivery MS-DRG. As stated in the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20220), in our proposal for restructuring the MDC 14 MS-DRGs under the ICD-10 MS-DRGs Version 36, diagnoses described as occurring during pregnancy and diagnoses specifying a trimester or maternal care in the absence of a delivery procedure reported are considered antepartum conditions. Also, as shown in Table 6P.1j. associated with the proposed rule (available via the internet on the CMS website at: https://www.cms.gov/Medicare/Medicare-Fee-for-Service-Payment/AcuteInpatientPPS/FY2019-IPPS-Proposed-Rule-Home-Page-Items/FY2019-IPPS-Proposed-Rule-Tables.html?DLPage=1&DLEntries=10&DLSort=0&DLSortDir=ascending), we did not propose to include any diagnosis codes describing a condition as ``complicating childbirth'' in the list of diagnosis codes describing antepartum conditions. Therefore, the diagnosis codes described as ``complicating childbirth'' would be applicable when a patient is admitted for a delivery episode and are subject to MS-DRG assignment to proposed MS-DRGs describing a cesarean or vaginal delivery. Comment: Another commenter agreed with CMS' initiative to restructure the MS-DRGs and GROUPER logic under MDC 14. However, the commenter expressed concerns with the proposed GROUPER logic, and requested CMS consider all of the issues prior to implementing the proposed new MS-DRGs and GROUPER logic. The commenter believed that grouping a vaginal delivery by procedure codes describing a delivery and a diagnosis code describing the outcome of delivery did not seem appropriate. The commenter stated that it is necessary to determine if a case should be assigned to a vaginal delivery MS-DRG based on the combination of principal diagnoses and procedure codes versus the combination of a procedure code with an outcome of delivery code. The commenter recommended that the first consideration should consist of identification of a principal diagnosis code within the O00-O08 code range (Pregnancy with Abortive Outcome) and then proceeding with grouping those cases to the Abortion MS-DRGs 770 (Abortion with D&C, Aspiration Curettage or Hysterotomy) and 779 (Abortion without D&C), prior to possibly grouping the cases to the cesarean or vaginal delivery MS-DRGs. The commenter provided the example of a blighted ovum that may be treated with ICD-10-PCS procedure codes 10D07Z6 (Extraction of products of conception, vacuum, via natural or artificial opening) or 10D07Z8 (Extraction of products of conception, other, via natural or artificial opening), which are reported for vaginal deliveries. Response: We appreciate the commenter's support for the effort to restructure the MS-DRGs and GROUPER logic under MDC 14. However, with respect to the commenter's concerns regarding the proposed new GROUPER logic for a vaginal delivery, we disagree with the commenter that it is necessary to determine if cases should be assigned to a vaginal delivery MS-DRG based on the combination of principal diagnoses and procedure codes versus the combination of a procedure code with an outcome of delivery code. One of the underlying purposes of the effort to restructure the vaginal delivery MS-DRGs was to simplify the complex logic currently associated with the vaginal delivery MS-DRGs, which includes multiple code lists for principal and secondary diagnoses. Based on the proposed new structure and GROUPER logic of the MS-DRGs under MDC 14, to identify that a vaginal delivery occurred, the logic does not have to consider or depend on the reason the patient was admitted. Rather, the GROUPER logic is structured to account for the fact that a delivery took place during that hospitalization. The delivery MS-DRGs (whether cesarean or vaginal) are specifically intended for that reason. With regard to the example provided by the commenter, we note that ICD-10-PCS procedure codes 10D07Z6 and 10D07Z8 are designated as non-O.R. procedures that affect the MS-DRG assignment of specific MS-DRGs. ICD-10-PCS procedure codes 10D07Z6 and 10D07Z8 impact the MS-DRG assignment of the vaginal delivery MS-DRGs. However, ICD-10-CM diagnosis code O02.0 (Blighted ovum and nonhydatidiform mole) is identified as a proposed antepartum condition, as shown in Table 6P.1j. associated with the proposed rule (available via the internet on the CMS website at: https://www.cms.gov/Medicare/Medicare-Fee-for-Service-Payment/AcuteInpatientPPS/FY2019-IPPS-Proposed-Rule-Home-Page-Items/FY2019-IPPS-Proposed-Rule-Tables.html?DLPage=1&DLEntries=10&DLSort=0&DLSortDir=ascending) and, therefore, as depicted in the commenter's example, if a patient has a principal diagnosis of a blighted ovum and either ICD-10-PCS procedure code 10D07Z6 or 10D07Z8 is reported, the proposed new GROUPER logic would result in an MS-DRG case assignment to one of the proposed new MS-DRGs 831, 832, or 833 (Other Antepartum Diagnoses without O.R. Procedure with MCC, with CC or without CC/MCC, respectively) and not a vaginal delivery MS-DRG. The diagnosis of a blighted ovum does not result in a viable pregnancy and, therefore, an outcome of delivery diagnosis code would not be reported. An illustration of how this proposed new GROUPER logic would apply for antepartum conditions was represented in Diagram 2 of the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20225). Comment: One commenter expressed concern about the proposed relative weights for several of the proposed new MS-DRGs under MDC 14. The commenter stated that the low volume of the procedures assigned to these MS-DRGs accounted for volatility in the relative weights. With regard to proposed new MS-DRGs 817, 818, and 819 (Other Antepartum Diagnoses with O.R. Procedure with MCC, CC, and without CC/MCC, respectively), the commenter stated that the proposed relative weights for these MS-DRGs are significantly lower than the proposed relative weights of the surgical MS-DRGs to which the procedure codes proposed to be assigned to these proposed new MS-DRGs would map for non- obstetrical patients. This commenter also stated that the relative weights for proposed new MS-DRGs 806 and 807 (Vaginal Delivery without Sterilization/D&C with CC and without CC/MCC, respectively) are lower than the current relative weights for MS-DRGs 774 and 775 (Vaginal Delivery with and without Complicating Diagnosis, respectively), and believed the relative weight for proposed new MS-DRG 805 (Vaginal Delivery without Sterilization/D&C with MCC) is likely inadequate for the resources required to care for patients with MCC severity level designations. The commenter suggested that CMS maintain the relative weights for proposed new MS-DRGs 806 and 807 at the same value of [[Page 41216]] the current MS-DRGs, and establish a relative weight for proposed new MS-DRG 805 that is more comparable with those values of medical MS-DRGs with MCC severity level designations. The commenter further noted that the relative weights for proposed new MS-DRGs 797 and 798 (Vaginal Delivery with Sterilization/D&C with CC and without CC/MCC, respectively) are the same value, but believed the relative weight should be greater for proposed new MS-DRG 797. The commenter also believed that the relative weight for proposed new MS-DRG 786 (Cesarean Section without Sterilization with MCC) is insufficient for the required resources necessary to perform these procedures and provide the appropriate care to patients, and requested CMS establish a relative weight with a value more consistent with values of surgical MS-DRGs with MCC severity level designations. The commenter also requested that CMS maintain the relative weights for MS-DRG 787 (Cesarean Section without Sterilization with CC) at the same value of current MS-DRG 765 (Cesarean Section with CC/MCC), and the relative weight for proposed new MS-DRG 833 (Other Antepartum Diagnoses without O.R. Procedure without CC/MCC) at the same value of current MS-DRG 782 (Other Antepartum Diagnoses without Medical Complications). Response: It is to be expected that when MS-DRGs are restructured, resulting in a different case-mix within the new MS-DRGs, the relative weights of the MS-DRGs will change as a result. With respect to the comment about the low volume of cases, as we have noted in the proposed rule, we were unable to use our usual criterion of ensuring that there are at least 500 cases in the MCC or CC group to refine the maternity MS-DRGs because of the extremely low volume of Medicare patients cases reflected in claims data for these DRGs. While there is not a high volume of these cases represented in the Medicare data, and while we generally advise that other payers should develop MS-DRGs to address the needs of their patients, we continue to believe that the restructured MS-DRGs within MDC 14 serve important purposes to account for the new and different clinical concepts that exist under ICD-10 for this subset of patients while also maintaining the existing MS-DRG structure for identifying severity of illness, utilization of resources, and complexity of service. We believe that even though some of the resulting MS-DRGs have relatively low volumes in the Medicare population, using our established methodology for developing DRG relative weights is the most appropriate approach for the new MS-DRGs within MDC 14. With regard to the comment about MS-DRGs 797 and 798, we note that the average cost per case for MS-DRG 797 was lower than the average cost per case for MS-DRG 798. Therefore, we blended the data for these two MS-DRGs to avoid nonmonotonocity, in which the lower severity MS-DRG has a higher relative weight than the higher severity MS-DRG. For these reasons, we are not finalizing a change to the calculation of the relative weights for the MS-DRGs under MDC 14. After consideration of the public comments we received, we are finalizing our proposals, without modification, including the list of diagnosis codes assigned to the MS-DRGs under the restructuring of the vaginal delivery MS-DRGs under MDC 14, which we note also addresses the list of diagnosis codes that a commenter identified and were noted in the proposed rule as appearing to be missing from the GROUPER logic. We also invited public comments on our proposal to reassign ICD-10- PCS procedure codes 0UDB7ZX, 0UDB7ZZ, 0UDB8ZX, and 0UDB8ZZ that describe dilation and curettage procedures from MS-DRG 767 under MDC 14 to MS-DRGs 744 and 745 under MDC 13. Comment: Commenters supported CMS' proposal to reassign ICD-10-PCS procedure codes 0UDB7ZX, 0UDB7ZZ, 0UDB8ZX, and 0UDB8ZZ from MS-DRG 767 to MS-DRGs 744 and 745. Response: We appreciate the commenters' support. After consideration of the public comments we received, we are finalizing our proposal to reassign ICD-10-PCS procedure codes 0UDB7ZX, 0UDB7ZZ, 0UDB8ZX, and 0UDB8ZZ that describe dilation and curettage procedures from MS-DRG 767 under MDC 14 to MS-DRGs 744 and 745 under MDC 13 in the ICD-10 MS-DRGs Version 36, effective October 1, 2018. After consideration of the public comments we received, we are finalizing our proposed list of diagnosis and procedure codes for assignment to the revised MDC 14 MS-DRGs including the deletion of 10 MS-DRGs and the creation of 18 new MS-DRGs in the ICD-10 MS-DRGs Version 36, effective October 1, 2018. 11. MDC 18 (Infectious and Parasitic Diseases (Systematic or Unspecified Sites): Systemic Inflammatory Response Syndrome (SIRS) of Non-Infectious Origin ICD-10-CM diagnosis codes R65.10 (Systemic Inflammatory Response Syndrome (SIRS) of non-infectious origin without acute organ dysfunction) and R65.11 (Systemic Inflammatory Response Syndrome (SIRS) of non-infectious origin with acute organ dysfunction) are currently assigned to MS-DRGs 870 (Septicemia or Severe Sepsis with Mechanical Ventilation >96 Hours), 871 (Septicemia or Severe Sepsis with Mechanical Ventilation >96 Hours with MCC), and 872 (Septicemia or Severe Sepsis with Mechanical Ventilation >96 Hours without MCC) under MDC 18 (Infectious and Parasitic Diseases, Systemic or Unspecified Sites). As discussed in the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20226), our clinical advisors noted that these diagnosis codes are specifically describing conditions of a non-infectious origin, and recommended that they be reassigned to a more clinically appropriate MS-DRG. We examined claims data from the September 2017 update of the FY 2017 MedPAR file for cases in MS-DRGs 870, 871, and 872. Our findings are shown in the following table. Septicemia or Severe Sepsis With and Without Mechanical Ventilation >96 Hours With and Without MCC ---------------------------------------------------------------------------------------------------------------- Number of Average length MS-DRG cases of stay Average costs ---------------------------------------------------------------------------------------------------------------- MS-DRG 870--All cases........................................... 31,658 14.3 $42,981 MS-DRG 871--All cases........................................... 566,531 6.3 13,002 MS-DRG 872--All cases........................................... 150,437 4.3 7,532 ---------------------------------------------------------------------------------------------------------------- As shown in this table, we found a total of 31,658 cases in MS-DRG 870, with an average length of stay of 14.3 days and average costs of $42,981. We found a total of 566,531 cases in MS-DRG 871, with an average length of stay [[Page 41217]] of 6.3 days and average costs of $13,002. Lastly, we found a total of 150,437 cases in MS-DRG 872, with an average length of stay of 4.3 days and average costs of $7,532. We then examined claims data in MS-DRGs 870, 871, or 872 for cases reporting an ICD-10-CM diagnosis code of R65.10 or R65.11. Our findings are shown in the following table.

We found a total of 138 cases reporting a principal diagnosis code of R65.11 in MS-DRGs 870, 871, and 872, with an average length of stay of 4.8 days and average costs of $9,655. We found a total of 1,232 cases reporting a secondary diagnosis code of R65.10 in MS-DRGs 870, 871, and 872, with an average length of stay of 5.5 days and average costs of $10,670. Lastly, we found a total of 117 cases reporting a secondary diagnosis code of R65.11 in MS-DRGs 870, 871, and 872, with an average length of stay of 6.2 days and average costs of $12,525. The claims data included a total of 1,392 cases in MS-DRGs 870, 871, and 872 that reported a principal diagnosis code of R65.10 or R65.11. We noted in the FY 2019 IPPS/LTCH PPS proposed rule that these 1,392 cases appear to have been coded inaccurately according to the ICD-10-CM Official Guidelines for Coding and Reporting at Section I.C.18.g., which specifically state: ``The systemic inflammatory response syndrome (SIRS) can develop as a result of certain non- infectious disease processes, such as trauma, malignant neoplasm, or pancreatitis. When SIRS is documented with a non-infectious condition, and no subsequent infection is documented, the code for the underlying condition, such as an injury, should be assigned, followed by code R65.10, Systemic inflammatory response syndrome (SIRS) of non- infectious origin without acute organ dysfunction or code R65.11, Systemic inflammatory response syndrome (SIRS) of non-infectious origin with acute organ dysfunction.'' Therefore, according to the Coding Guidelines, ICD-10-CM diagnosis codes R65.10 and R65.11 should not be reported as the principal diagnosis on an inpatient claim. We have acknowledged in past rulemaking the challenges with coding for SIRS (and sepsis) (71 FR 24037). In addition, we note that there has been confusion with regard to how these codes are displayed in the ICD-10 MS-DRG Definitions Manual under MS-DRGs 870, 871, and 872, which may also impact the reporting of these conditions. For example, in Version 35 of the ICD-10 MS-DRG Definitions Manual (which is available via the internet on the CMS website at: https://www.cms.gov/Medicare/Medicare-Fee-for-Service-Payment/AcuteInpatientPPS/FY2018-IPPS-Final-Rule-Home-Page-Items/FY2018-IPPS-Final-Rule-Data-Files.html?DLPage=1&DLEntries=10&DLSort=0&DLSortDir=ascending, the logic for case assignment to MS-DRGs 870, 871, and 872 is comprised of a list of several diagnosis codes, of which ICD-10-CM diagnosis codes R65.10 and R65.11 are included. Because these codes are listed under the heading of ``Principal Diagnosis'', it may appear that these codes are to be reported as a principal diagnosis for assignment to MS-DRGs 870, 871, or 872. However, the Definitions Manual display of the GROUPER logic assignment for each diagnosis code is for grouping purposes only. The GROUPER (and, therefore, documentation in the MS-DRG Definitions Manual) was not designed to account for coding guidelines or coverage policies. Since the inception of the IPPS, the data editing function has been a separate and independent step in the process of determining a DRG assignment. Except for extreme data integrity issues that prevent a DRG from being assigned, such as an invalid principal diagnosis, the DRG assignment GROUPER does not edit for data integrity. Prior to assigning the MS-DRG to a claim, the MACs apply a series of data integrity edits using programs such as the Medicare Code Editor (MCE). The MCE is designed to identify cases that require further review before classification into an MS-DRG. These data integrity edits address issues such as data validity, coding rules, and coverage policies. The separation of the MS-DRG grouping and data editing functions allows the MS-DRG GROUPER to remain stable during a fiscal year even though coding rules and coverage policies may change during the fiscal year. As such, in the FY 2018 IPPS/LTCH PPS final rule (82 FR 38050 through 38051), we finalized our proposal to add ICD-10-CM diagnosis codes R65.10 and R65.11 to the Unacceptable Principal Diagnosis edit in the MCE as a result of the Official Guidelines for Coding and Reporting related to SIRS, in efforts to improve coding accuracy for these types of cases. To address the issue of determining a more appropriate MS-DRG assignment for ICD-10-CM diagnosis codes R65.10 and R65.11, we reviewed alternative options under MDC 18. Our clinical advisors determined the most appropriate option is MS-DRG 864 (Fever) because the conditions that are assigned here describe conditions of a non-infectious origin. Therefore, in the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20227), we proposed to reassign ICD-10-CM diagnosis codes R65.10 and R65.11 to MS-DRG 864 and to revise the title of MS-DRG 864 to ``Fever and Inflammatory Conditions'' to better reflect the diagnoses assigned there. [[Page 41218]] Proposed Revised MS-DRG 864 (Fever and Inflammatory Conditions) ---------------------------------------------------------------------------------------------------------------- Average length MS-DRG Number of cases of stay Average costs ---------------------------------------------------------------------------------------------------------------- MS-DRG 864--All cases........................................ 12,144 3.4 $6,232 ---------------------------------------------------------------------------------------------------------------- Comment: Commenters supported the proposal to reassign ICD-10-CM diagnosis codes R65.10 and R65.11 to MS-DRG 864 and to revise the title of MS-DRG 864 to ``Fever and Inflammatory Conditions''. Response: We thank the commenters for their support. Comment: One commenter questioned the proposed logic for ICD-10-CM diagnosis codes R65.10 and R65.11 within MS-DRG 864. The commenter noted that the diagnosis codes are included on the unacceptable principal diagnoses code edit list in the MCE and specifically inquired if cases reporting diagnosis code R65.10 or R65.11 as a secondary diagnosis would result in assignment to MS-DRG 864. Response: The GROUPER logic assignment for each diagnosis code as a principal diagnosis is for grouping purposes only. The GROUPER was not designed to account for coding guidelines or coverage policies. The MCE is designed to identify cases that require further review before classification into an MS-DRG. Therefore, the MS-DRG logic must specifically require a condition to group based on whether it is reported as a principal diagnosis or a secondary diagnosis, and consider any procedures that are reported, in addition to consideration of the patient's age, sex and discharge status in order to affect the MS-DRG assignment. As noted in the ICD-10 MS-DRG Definitions Manual Version 35, Appendix B--Diagnosis Code/MDC/MS-DRG Index, each diagnosis code is listed with the MDC and the MS-DRGs to which the diagnosis is used to define the logic of the DRG either as a principal diagnosis or a secondary diagnosis. For diagnosis codes R65.10 and R65.11, the ICD-10 MS DRG Definitions Manual displays MDC 18 and MS-DRGs 870-872, as described previously. As discussed in the proposed rule, because the diagnosis are codes listed under the heading of ``Principal Diagnosis'' in the ICD-10 MS DRG Definitions Manual, it may appear to indicate that these codes are to be reported as a principal diagnosis for assignment to these MS-DRGs. However, the Definitions Manual display of the GROUPER logic assignment for each diagnosis code is for grouping purposes only and does not correspond to coding guidelines for reporting the principal diagnosis. In other words, cases will group according to the GROUPER logic, regardless of any coding guidelines or coverage policies. It is the MCE and other payer specific edits that identify inconsistencies in the coding guidelines or coverage policies. Under our proposed change to the ICD-10 MS-DRGs Version 36, cases reporting diagnosis code R65.10 or R65.11 as a secondary diagnosis would result in assignment to MS-DRG 864 when one of the other listed diagnosis codes in the MS-DRG 864 logic is reported as the principal diagnosis. After consideration of the public comments we received, we are finalizing our proposal to reassign ICD-10-CM diagnosis codes R65.10 and R65.11 to MS-DRG 864 and to revise the title of MS-DRG 864 to ``Fever and Inflammatory Conditions''. 12. MDC 21 (Injuries, Poisonings and Toxic Effects of Drugs): Corrosive Burns ICD-10-CM Coding Guidelines include ``Code first'' sequencing instructions for cases reporting a principal diagnosis of toxic effect (ICD-10-CM codes T51 through T65) and a secondary diagnosis of corrosive burn (ICD-10-CM codes T21.40 through T21.79). As discussed in the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20227), we received a request to reassign these cases from MS-DRGs 901 (Wound Debridements for Injuries with MCC), 902 (Wound Debridements for Injuries with CC), 903 (Wound Debridements for Injuries without CC/MCC), 904 (Skin Grafts for Injuries with CC/MCC), 905 (Skin Grafts for Injuries without CC/ MCC), 917 (Poisoning and Toxic Effects of Drugs with MCC), and 918 (Poisoning and Toxic Effects of Drugs without MCC) to MS-DRGs 927 (Extensive Burns or Full Thickness Burns with Mechanical Ventilation >96 Hours with Skin Graft), 928 (Full Thickness Burn with Skin Graft or Inhalation Injury with CC/MCC), 929 (Full Thickness Burn with Skin Graft or Inhalation Injury without CC/MCC), 933 (Extensive Burns or Full Thickness Burns with Mechanical Ventilation >96 Hours without Skin Graft), 934 (Full Thickness Burn without Skin Graft or Inhalation Injury), and 935 (Nonextensive Burns). The requestor noted that, for corrosion burns codes T21.40 through T21.79, ICD-10-CM Coding Guidelines instruct to ``Code first (T51 through T65) to identify chemical and intent.'' Because code first notes provide sequencing directive, when patients are admitted with corrosive burns (which can be full thickness and extensive), toxic effect codes T51 through T65 must be sequenced first followed by codes for the corrosive burns. This causes full-thickness and extensive burns to group to MS-DRGs 901 through 905 when excisional debridement and split thickness skin grafts are performed, and to MS-DRGs 917 and 918 when procedures are not performed. This is in contrast to cases reporting a principal diagnosis of corrosive burn, which group to MS- DRGs 927 through 935. The requestor stated that MS-DRGs 456 (Spinal Fusion except Cervical with Spinal Curvature or Malignancy or Infection or Extensive Fusions with MCC), 457 (Spinal Fusion Except Cervical with Spinal Curvature or Malignancy or Infection or Extensive Fusions with CC), and 458 (Spinal Fusion Except Cervical with Spinal Curvature or Malignancy or Infection or Extensive Fusions without CC/MCC) are grouped based on the procedure performed in combination with the principal diagnosis or secondary diagnosis (secondary scoliosis). The requestor stated that when codes for corrosive burns are reported as secondary diagnoses in conjunction with principal diagnoses codes T5l through T65, particularly when skin grafts are performed, they would be more appropriately assigned to MS-DRGs 927 through 935. We analyzed claims data from the September 2017 update of the FY 2017 MedPAR file for all cases assigned to MS-DRGs 901, 902, 903, 904, 905, 917, and 918, and subsets of these cases with principal diagnosis of toxic effect with secondary diagnosis of corrosive burn. We noted in the proposed rule that we found no cases from this subset in MS-DRGs 903, 907, 908, and 909 and, therefore, did not include the results for these MS-DRGs in the table below. We also analyzed all cases assigned to MS-DRGs 927, 928, 929, 933, 934, and 935 and those cases that reported a principal diagnosis of corrosive burn. Our findings are shown in the following two tables.

When comparing this subset of codes relative to those of each MS-DRG as a whole, we noted that, in most of these MS-DRGs, the average costs and average length of stay for this subset of cases were roughly equivalent to or lower than the average costs and average length of stay for cases in the MS-DRG as a whole, while in one case, they were higher. As we have noted in prior rulemaking (77 FR 53309) and elsewhere in the proposed rule and this final rule, it is a fundamental principle of an averaged payment system that half of the procedures in a group will have above average costs. It is expected that there will be higher cost and lower cost subsets, especially when a subset has low numbers. We stated in the proposed rule that the results of this analysis indicate that these cases are appropriately placed within their current MDC. Our clinical advisors reviewed this request and indicated that patients with a principal diagnosis of toxic effect and a secondary diagnosis of corrosive burn have been exposed to an irritant or corrosive substance and, therefore, are clinically similar to those patients in MDC 21. Furthermore, our clinical advisors did not believe that the size of this subset of cases justifies the significant changes to the GROUPER logic that would be required to address the commenter's request, which would involve rerouting cases when the primary and secondary diagnoses are in different MDCs.

We found a total of 60 cases reporting a principal diagnosis of corrosive burn, with an average length of stay of 8.5 days and average costs of $19,456. We stated in the proposed rule that our clinical advisors believe that these cases reporting a principal diagnosis of corrosive burn are appropriately placed in MDC 22 as they are clinically aligned with other patients in this MDC. We further stated that, in [[Page 41220]] summary, the results of our claims data analysis and the advice from our clinical advisors do not support reassigning cases in MS-DRGs 901, 902, 903, 904, 905, 917, and 918 reporting a principal diagnosis of toxic effect and a secondary diagnosis of corrosive burn to MS-DRGs 927, 928, 929, 933, 934 and 935. Therefore, we did not propose to reassign these cases. Comment: One commenter supported the proposal to maintain the current MS-DRG structure for cases reporting a principal diagnosis of toxic effect (ICD-10-CM codes T51 through T65) and a secondary diagnosis of corrosive burn (ICD-10-CM codes T21.40 through T21.79). Another commenter suggested that the 60 identified cases that CMS used in its analysis were incorrectly coded. The commenter noted that ICD- 10-CM coding guidelines under each code for corrosion burn state ``Code first (T51-T65) to identify chemical and intent.'' The commenter stated that corrosive burns cannot be sequenced as the principal diagnosis because the coding guidelines must be followed. The commenter stated that the toxic effect codes T51-T65 must be sequenced first, which causes these cases to group to MS-DRGs 901 through 905 and 917 and 918 instead of the more appropriate burn MS-DRGs. The commenter stated that it appears that when codes T51-T65 are the principal diagnosis, the cases group to MDC 21 (Injuries, Poisoning. and Toxic Effects of Drugs), and then to MS-DRGs 901 through 905 and 917 and 918. Response: We appreciate the commenter's support. With regard to the commenter who raised concerns about the coding guidelines and display of codes in the ICD-10 MS-DRG Definitions Manual, we note that the GROUPER logic was not designed to account for coding guidelines. With regard to the display of code lists in the ICD-10 MS-DRG Definitions Manual, the MS-DRG logic must specifically require a condition to group based on whether it is reported as a principal diagnosis or a secondary diagnosis and consider any procedures that are reported in order to affect the MS-DRG assignment. However, as stated previously, the GROUPER logic is not dependent on coding guidelines. The purpose of the GROUPER is to group cases into particular MS-DRGs. We recognize that, over time, the desire to create or modify existing GROUPER logic in response to coding guidelines has become more common. As we continue our efforts to refine the ICD-10 MS-DRGs, we will consider alternate approaches to ensure the integrity of both the GROUPER logic and coding guidelines. Based on the data available at this time, we do not believe that it is appropriate to change the MS-DRG assignment for the procedures identifying corrosive burns identified earlier. After consideration of the public comments we received, we are finalizing our proposal to maintain the current MS-DRG structure for cases reporting a principal diagnosis of toxic effect (ICD-10-CM codes T51 through T65) and a secondary diagnosis of corrosive burn (ICD-10-CM codes T21.40 through T21.79). 13. Changes to the Medicare Code Editor (MCE) The Medicare Code Editor (MCE) is a software program that detects and reports errors in the coding of Medicare claims data. Patient diagnoses, procedure(s), and demographic information are entered into the Medicare claims processing systems and are subjected to a series of automated screens. The MCE screens are designed to identify cases that require further review before classification into an MS-DRG. As discussed in the FY 2018 IPPS/LTCH PPS final rule (82 FR 38045), we made available the FY 2018 ICD-10 MCE Version 35 manual file. The link to this MCE manual file, along with the link to the mainframe and computer software for the MCE Version 35 (and ICD-10 MS-DRGs) are posted on the CMS website at https://www.cms.gov/Medicare/Medicare-Fee-for-Service-Payment/AcuteInpatientPPS/index.html through the FY 2018 IPPS Final Rule Home Page. In the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20229), we addressed the MCE requests we received by the November 1, 2017 deadline. We also discussed the proposals we were making based on our internal review and analysis. In this FY 2019 IPPS/LTCH PPS final rule, we present a summation of the comments we received in response to the MCE requests and proposals presented based on internal reviews and analyses in the proposed rule, our responses to those comments, and our finalized policies. In addition, as a result of new and modified code updates approved after the annual spring ICD-10 Coordination and Maintenance Committee meeting, we routinely make changes to the MCE. In the past, in both the IPPS proposed and final rules, we only provided the list of changes to the MCE that were brought to our attention after the prior year's final rule. We historically have not listed the changes we have made to the MCE as a result of the new and modified codes approved after the annual spring ICD-10 Coordination and Maintenance Committee meeting. These changes are approved too late in the rulemaking schedule for inclusion in the proposed rule. Furthermore, although our MCE policies have been described in our proposed and final rules, we have not provided the detail of each new or modified diagnosis and procedure code edit in the final rule. However, we make available the finalized Definitions of Medicare Code Edits (MCE) file. Therefore, we are making available the FY 2019 ICD-10 MCE Version 36 Manual file, along with the link to the mainframe and computer software for the MCE Version 36 (and ICD-10 MS DRGs), on the CMS website at: https://www.cms.gov/Medicare/Medicare-Fee-for-Service-Payment/AcuteInpatientPPS/MS-DRG-Classifications-and-Software.html. a. Age Conflict Edit In the MCE, the Age Conflict edit exists to detect inconsistencies between a patient's age and any diagnosis on the patient's record; for example, a 5-year-old patient with benign prostatic hypertrophy or a 78-year-old patient coded with a delivery. In these cases, the diagnosis is clinically and virtually impossible for a patient of the stated age. Therefore, either the diagnosis or the age is presumed to be incorrect. Currently, in the MCE, the following four age diagnosis categories appear under the Age Conflict edit and are listed in the manual and written in the software program: Perinatal/Newborn--Age of 0 years only; a subset of diagnoses which will only occur during the perinatal or newborn period of age 0 (for example, tetanus neonatorum, health examination for newborn under 8 days old). Pediatric--Age is 0-17 years inclusive (for example, Reye's syndrome, routine child health exam). Maternity--Age range is 12-55 years inclusive (for example, diabetes in pregnancy, antepartum pulmonary complication). Adult--Age range is 15-124 years inclusive (for example, senile delirium, mature cataract). (1) Perinatal/Newborn Diagnoses Category Under the ICD-10 MCE, the Perinatal/Newborn Diagnoses category under the Age Conflict edit considers the age of 0 years only; a subset of diagnoses which will only occur during the perinatal or newborn period of age 0 to be inclusive. This includes conditions that have their origin in the fetal or perinatal period (before birth through the first 28 days [[Page 41221]] after birth) even if morbidity occurs later. For that reason, the diagnosis codes on this Age Conflict edit list would be expected to apply to conditions or disorders specific to that age group only. In the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20229), we indicated that, in the ICD-10-CM classification, there are 14 diagnosis codes that describe specific suspected conditions that have been evaluated and ruled out during the newborn period and are currently not on the Perinatal/Newborn Diagnoses Category edit code list. We consulted with staff at the Centers for Disease Control's (CDC's) National Center for Health Statistics (NCHS) because NCHS has the lead responsibility for the ICD-10-CM diagnosis codes. The NCHS' staff confirmed that the following diagnosis codes are appropriate to add to the edit code list for the Perinatal/Newborn Diagnoses Category. ------------------------------------------------------------------------ ICD-10-CM code Code description ------------------------------------------------------------------------ Z05.0..................... Observation and evaluation of newborn for suspected cardiac condition ruled out. Z05.1..................... Observation and evaluation of newborn for suspected infectious condition ruled out. Z05.2..................... Observation and evaluation of newborn for suspected neurological condition ruled out. Z05.3..................... Observation and evaluation of newborn for suspected respiratory condition ruled out. Z05.41.................... Observation and evaluation of newborn for suspected genetic condition ruled out. Z05.42.................... Observation and evaluation of newborn for suspected metabolic condition ruled out. Z05.43.................... Observation and evaluation of newborn for suspected immunologic condition ruled out. Z05.5..................... Observation and evaluation of newborn for suspected gastrointestinal condition ruled out. Z05.6..................... Observation and evaluation of newborn for suspected genitourinary condition ruled out. Z05.71.................... Observation and evaluation of newborn for suspected skin and subcutaneous tissue condition ruled out. Z05.72.................... Observation and evaluation of newborn for suspected musculoskeletal condition ruled out. Z05.73.................... Observation and evaluation of newborn for suspected connective tissue condition ruled out. Z05.8..................... Observation and evaluation of newborn for other specified suspected condition ruled out. Z05.9..................... Observation and evaluation of newborn for unspecified suspected condition ruled out. ------------------------------------------------------------------------ Therefore, we proposed to add the ICD-10-CM diagnosis codes listed in the table above to the Age Conflict edit under the Perinatal/Newborn Diagnoses Category edit code list. We also proposed to continue to include the existing diagnosis codes currently listed under the Perinatal/Newborn Diagnoses Category edit code list. Comment: Commenters agreed with CMS' proposal to add the diagnosis codes listed in the table above to the Age Conflict edit under the Perinatal/Newborn Diagnoses Category edit code list. Response: We appreciate the commenters' support. After consideration of the public comments we received, we are finalizing our proposal to add the ICD-10-CM diagnosis codes listed in the table above to the Age Conflict edit under the Perinatal/Newborn Diagnoses Category edit code list. We also are finalizing our proposal to continue to include the existing list of codes on the Perinatal/ Newborn Diagnoses Category edit code list under the ICD-10 MCE Version 36, effective October 1, 2018. (2) Pediatric Diagnoses Category Under the ICD-10 MCE, the Pediatric Diagnoses Category for the Age Conflict edit considers the age range of 0 to 17 years inclusive. For that reason, the diagnosis codes on this Age Conflict edit list would be expected to apply to conditions or disorders specific to that age group only. As discussed in section II.F.15. of the preamble of the proposed rule, Table 6C.--Invalid Diagnosis Codes associated with the proposed rule and this final (which is available via the internet on the CMS website at: http://www.cms.hhs.gov/Medicare/Medicare-Fee-for-Service-Payment/AcuteInpatientPPS/index.html) lists the diagnoses that will no longer be effective as of October 1, 2018. Included in this table is an ICD-10-CM diagnosis code currently listed on the Pediatric Diagnoses Category edit code list, ICD-10-CM diagnosis code Z13.4 (Encounter for screening for certain developmental disorders in childhood). In the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20230), we proposed to remove this code from the Pediatric Diagnoses Category edit code list. We also proposed to continue to include the other existing diagnosis codes currently listed under the Pediatric Diagnoses Category edit code list. Comment: Commenters agreed with the proposal to remove ICD-10-CM diagnosis code Z13.4 from the Pediatric Diagnoses Category edit code list because this code will no longer be effective as of October 1, 2018. Response: We appreciate the commenters' support. After consideration of the public comments we received, we are finalizing our proposal to remove ICD-10-CM diagnosis code Z13.4 from the Pediatric Diagnoses Category edit code list. We also are finalizing our proposal to maintain the other existing codes on the Pediatric Diagnoses Category edit code list under the ICD-10 MCE Version 36, effective October 1, 2018. (3) Maternity Diagnoses Under the ICD-10 MCE, the Maternity Diagnoses Category for the Age Conflict edit considers the age range of 12 to 55 years inclusive. For that reason, the diagnosis codes on this Age Conflict edit list would be expected to apply to conditions or disorders specific to that age group only. As discussed in section II.F.15. of the preamble of the proposed rule, Table 6A.--New Diagnosis Codes associated with the proposed rule (which is available via the internet on the CMS website at: http://www.cms.hhs.gov/Medicare/Medicare-Fee-for-Service-Payment/AcuteInpatientPPS/index.html) listed the new diagnoses codes that had been approved to date, which will be effective with discharges occurring on and after October 1, 2018. The following table lists the new ICD-10-CM diagnosis codes included in Table 6A associated with pregnancy and maternal care that we stated we believe are appropriate to add to the Maternity Diagnoses Category edit code list under the Age Conflict edit. Therefore, in the proposed rule, we proposed to add these codes to the Maternity Diagnoses Category edit code list under the Age Conflict edit.

Included in this table are two ICD-10-CM diagnosis codes currently listed on the Maternity Diagnoses Category edit code list: ICD-10-CM diagnosis codes F53 (Puerperal psychosis) and O86.0 (Infection of obstetric surgical wound). In the proposed rule, we proposed to remove these codes from the Maternity Diagnoses Category Edit code list. We also proposed to continue to include the other existing diagnosis codes currently listed under the Maternity Diagnoses Category edit code list. Comment: Commenters agreed with the proposal to add the diagnosis codes listed in the table above to the Maternity Diagnoses Category edit code list. Commenters also agreed with the proposal to remove ICD- 10-CM diagnosis codes F53 and O86.0 from the Maternity Diagnoses Category edit code list. Response: We appreciate the commenters' support. After consideration of the public comments we received, we are finalizing our proposal to add the diagnosis codes listed in the table above to the Maternity Diagnoses Category edit code list and our proposal to remove ICD-10-CM diagnosis codes F53 and O86.0 from the Maternity Diagnoses Category edit code list. We also are finalizing our proposal to maintain the other existing codes on the Maternity Diagnoses Category edit code list under the ICD-10 MCE Version 36, effective October 1, 2018. b. Sex Conflict Edit In the MCE, the Sex Conflict edit detects inconsistencies between a patient's sex and any diagnosis or procedure on the patient's record; for example, a male patient with cervical cancer (diagnosis) or a female patient with a prostatectomy (procedure). In both instances, the indicated diagnosis or the procedure conflicts with the stated sex of the patient. Therefore, the patient's diagnosis, procedure, or sex is presumed to be incorrect. (1) Diagnoses for Females Only Edit In the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20231), we indicated that we received a request to consider the addition of the following ICD-10-CM diagnosis codes to the list for the Diagnoses for Females Only edit. ------------------------------------------------------------------------ ICD-10-CM code Code description ------------------------------------------------------------------------ Z30.015................... Encounter for initial prescription of vaginal ring hormonal contraceptive. Z31.7..................... Encounter for procreative management and counseling for gestational carrier. Z98.891................... History of uterine scar from previous surgery. ------------------------------------------------------------------------ The requestor noted that, currently, ICD-10-CM diagnosis code Z30.44 (Encounter for surveillance of vaginal ring hormonal contraceptive device) is on the Diagnoses for Females Only edit code list and suggested that ICD-10-CM diagnosis code Z30.015, which also describes an encounter involving a vaginal ring hormonal contraceptive, be added to the Diagnoses for Females Only edit code list as well. In addition, the requestor suggested that ICD-10-CM diagnosis codes Z31.7 and Z98.891 be added to the Diagnoses for Females Only edit code list. We reviewed ICD-10-CM diagnosis codes Z30.015, Z31.7, and Z98.891, and we agreed with the requestor that it is clinically appropriate to add these three ICD-10-CM diagnosis codes to the Diagnoses for Females Only edit code list because the conditions described by these codes are specific to and consistent with the female sex. In addition, as discussed in section II.F.15. of the preamble of the proposed rule, Table 6A.--New Diagnosis Codes associated with the proposed rule (which is available via the internet on the CMS website at: http://www.cms.hhs.gov/Medicare/Medicare-Fee-for-Service-Payment/AcuteInpatientPPS/index.html) listed [[Page 41223]] the new diagnosis codes that had been approved to date, which will be effective with discharges occurring on and after October 1, 2018. The following table lists the new diagnosis codes that are associated with conditions consistent with the female sex. We proposed to add these ICD-10-CM diagnosis codes to the Diagnoses for Females Only edit code list under the Sex Conflict edit. ------------------------------------------------------------------------ ICD-10-CM code Code description ------------------------------------------------------------------------ F53.0..................... Postpartum depression. F53.1..................... Puerperal psychosis. N35.82.................... Other urethral stricture, female. N35.92.................... Unspecified urethral stricture, female.

Q51.21.................... Other complete doubling of uterus. Q51.22.................... Other partial doubling of uterus. Q51.28.................... Other doubling of uterus, other specified. Z13.32.................... Encounter for screening for maternal depression. ------------------------------------------------------------------------ Comment: Commenters supported the proposals to add ICD-10-CM diagnosis codes Z30.015, Z31.7 and Z98.891 and the ICD-10-CM diagnosis codes listed in the table above to the Diagnoses for Females Only edit code list. Response: We appreciate the commenters' support. After consideration of the public comments we received, we are finalizing our proposals to add ICD-10-CM diagnosis codes Z30.015, Z31.7 and Z98.891 and the ICD-10-CM diagnosis codes listed in the table above to the Diagnoses for Females Only edit code list under the ICD-10 MCE Version 36, effective October 1, 2018. In addition, as discussed in section II.F.15. of the preamble of the proposed rule, Table 6C.--Invalid Diagnosis Codes associated with the proposed rule (which is available via the internet on the CMS website at: http://www.cms.hhs.gov/Medicare/Medicare-Fee-for-Service-Payment/AcuteInpatientPPS/index.html) listed the diagnosis codes that are no longer effective as of October 1, 2018. Included in this table were the following three ICD-10-CM diagnosis codes currently listed on the Diagnoses for Females Only edit code list. ------------------------------------------------------------------------ ICD-10-CM code Code description ------------------------------------------------------------------------ F53....................... Puerperal psychosis. O86.0..................... Infection of obstetric surgical wound. Q51.2..................... Other doubling of uterus, unspecified. ------------------------------------------------------------------------ Because these three ICD-10-CM diagnosis codes will no longer be effective as of October 1, 2018, we proposed to remove them from the Diagnoses for Females Only edit code list under the Sex Conflict edit. Comment: Commenters supported the proposal to remove ICD-10-CM diagnosis codes F53, O86.0, and Q51.2, from the Diagnoses for Females Only edit code list, as they are no longer valid effective October 1, 2018. One commenter also noted that there were typographical errors in the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20232) for diagnosis codes O86.0 and Q51.2, where an extra zero was inadvertently included as a fifth digit. Response: We appreciate the commenters' support. We agree with the commenter that there were typographical errors in the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20232) for diagnosis codes O86.0 and Q51.2, where an extra zero was inadvertently included as a fifth digit, and have corrected these errors in the table presented in this final rule preamble. After consideration of the public comments we received, we are finalizing our proposal to remove ICD-10-CM diagnosis codes F53, O86.0, and Q51.2, from the Diagnoses for Females Only edit code list under the ICD-10 MCE Version 36, effective October 1, 2018. [[Page 41224]] (2) Procedures for Females Only Edit As discussed in section II.F.15. of the preamble of the FY 2019 IPPS/LTCH PPS proposed rule, Table 6B.--New Procedure Codes associated with the proposed rule (which is available via the internet on the CMS website at: http://www.cms.hhs.gov/Medicare/Medicare-Fee-for-Service-Payment/AcuteInpatientPPS/index.html) listed the procedure codes that had been approved to date, which will be effective with discharges occurring on and after October 1, 2018. In the proposed rule, we proposed to add the three ICD-10-PCS procedure codes in the following table describing procedures associated with the female sex to the Procedures for Females Only edit code list. ------------------------------------------------------------------------ ICD-10-PCS code Code description ------------------------------------------------------------------------ 0UY90Z0................... Transplantation of uterus, allogeneic, open approach. 0UY90Z1................... Transplantation of uterus, syngeneic, open approach. 0UY90Z2................... Transplantation of uterus, zooplastic, open approach. ------------------------------------------------------------------------ We also proposed to continue to include the existing procedure codes currently listed under the Procedures for Females Only edit code list. Comment: Commenters supported the proposal to add ICD-10-PCS procedure codes 0UY90Z0, 0UY90Z1 and 0UY90Z2 to the Procedures for Females Only edit code list. Response: We appreciate the commenters' support. After consideration of the public comments we received, we are finalizing our proposal to add ICD-10-PCS procedure codes 0UY90Z0, 0UY90Z1 and 0UY90Z2 to the Procedures for Females Only edit code list. We also are finalizing our proposal to maintain the existing list of codes on the Procedures for Females Only edit code list under the ICD- 10 MCE Version 36, effective October 1, 2018. (3) Diagnoses for Males Only Edit As discussed in section II.F.15. of the preamble of the proposed rule, Table 6A.--New Diagnosis Codes associated with the proposed rule (which is available via the internet on the CMS website at: http://www.cms.hhs.gov/Medicare/Medicare-Fee-for-Service-Payment/AcuteInpatientPPS/index.html) listed the new diagnosis codes that had been approved to date, which will be effective with discharges occurring on and after October 1, 2018. The following table lists the new diagnosis codes that are associated with conditions consistent with the male sex. In the proposed rule, we proposed to add these ICD-10-CM diagnosis codes to the Diagnoses for Males Only edit code list under the Sex Conflict edit. ------------------------------------------------------------------------ ICD-10-CM code Code description ------------------------------------------------------------------------ N35.016...................

Comment: Commenters supported the proposal to add the ICD-10-CM diagnosis codes listed in the table above to the Diagnoses for Males Only edit code list. Response: We appreciate the commenters' support. After consideration of the public comments we received, we are finalizing our proposal to add the ICD-10-CM diagnosis codes listed in the table above to the Diagnoses for Males Only edit code list. We also are finalizing our proposal to maintain the existing list of codes on the Diagnoses for Males Only edit code list under the ICD-10 MCE Version 36, effective October 1, 2018. c. Manifestation Code as Principal Diagnosis Edit In the ICD-10-CM classification system, manifestation codes describe the manifestation of an underlying disease, not the disease itself and, therefore, should not be used as a principal diagnosis. In the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20232), we noted that, as discussed in section II.F.15. of the preamble of the proposed rule, Table 6A.--New Diagnosis Codes associated with the proposed rule (which is available via the internet on the CMS website at: http://www.cms.hhs.gov/Medicare/Medicare-Fee-for-Service-Payment/AcuteInpatientPPS/index.html) listed the new diagnosis codes that had been approved to date which will be effective with discharges [[Page 41225]] occurring on and after October 1, 2018. Included in this table are ICD- 10-CM diagnosis codes K82.A1 (Gangrene of gallbladder in cholecystitis) and K82.A2 (Perforation of gallbladder in cholecystitis). We proposed to add these two ICD-10-CM diagnosis codes to the Manifestation Code as Principal Diagnosis edit code list because the type of cholecystitis would be required to be reported first. We also proposed to continue to include the existing diagnosis codes currently listed under the Manifestation Code as Principal Diagnosis edit code list. We invited public comments on our proposals. Comment: Commenters supported the proposal to add ICD-10-CM diagnosis codes K82.A1 and K82.A2 to the Manifestation Code as Principal Diagnosis edit code list and to continue to include the existing diagnosis codes currently listed under the Manifestation Code as Principal Diagnosis edit code list. Response: We appreciate the commenters' support. After consideration of the public comments we received, we are finalizing our proposal to add ICD-10-CM diagnosis codes K82.A1 and K82.A2 to the Manifestation Code as Principal Diagnosis edit code list and to continue to include the existing diagnosis codes currently listed under the Manifestation Code as Principal Diagnosis edit code list under the ICD-10 MCE Version 36, effective October 1, 2018. d. Questionable Admission Edit In the MCE, some diagnoses are not usually sufficient justification for admission to an acute care hospital. For example, if a patient is assigned ICD-10-CM diagnosis code R03.0 (Elevated blood pressure reading, without diagnosis of hypertension), the patient would have a questionable admission because an elevated blood pressure reading is not normally sufficient justification for admission to a hospital. In the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20233), we noted that, as discussed in section II.F.10. of the preamble of the proposed rule, we were proposing several modifications to the MS-DRGs under MDC 14 (Pregnancy, Childbirth and the Puerperium). We stated in the proposed rule that one aspect of these proposed modifications involves the GROUPER logic for the cesarean section and vaginal delivery MS- DRGs. We referred readers to section II.F.10. of the preamble of the proposed rule for a detailed discussion of the proposals regarding these MS-DRG modifications under MDC 14 and the relation to the MCE. If a patient presents to the hospital and either a cesarean section or a vaginal delivery occurs, it is expected that, in addition to the specific type of delivery code, an outcome of delivery code is also assigned and reported on the claim. The outcome of delivery codes are ICD-10-CM diagnosis codes that are to be reported as secondary diagnoses as instructed in Section I.C.15.b.5 of the ICD-10-CM Official Guidelines for Coding and Reporting which states: ``A code from category Z37, Outcome of delivery, should be included on every maternal record when a delivery has occurred. These codes are not to be used on subsequent records or on the newborn record.'' Therefore, to encourage accurate coding and appropriate MS-DRG assignment in alignment with the proposed modifications to the delivery MS-DRGs, we proposed to create a new ``Questionable Obstetric Admission Edit'' under the Questionable Admission edit to read as follows: ``b. Questionable obstetric admission ICD-10-PCS procedure codes describing a cesarean section or vaginal delivery are considered to be a questionable admission except when reported with a corresponding secondary diagnosis code describing the outcome of delivery. Procedure code list for cesarean section 10D00Z0 Extraction of Products of Conception, High, Open Approach 10D00Z1 Extraction of Products of Conception, Low, Open Approach 10D00Z2 Extraction of Products of Conception, Extraperitoneal, Open Approach Procedure code list for vaginal delivery 10D07Z3 Extraction of Products of Conception, Low Forceps, Via Natural or Artificial Opening 10D07Z4 Extraction of Products of Conception, Mid Forceps, Via Natural or Artificial Opening 10D07Z5 Extraction of Products of Conception, High Forceps, Via Natural or Artificial Opening 10D07Z6 Extraction of Products of Conception, Vacuum, Via Natural or Artificial Opening 10D07Z7 Extraction of Products of Conception, Internal Version, Via Natural or Artificial Opening 10D07Z8 Extraction of Products of Conception, Other, Via Natural or Artificial Opening 10D17Z9 Manual Extraction of Products of Conception, Retained, Via Natural or Artificial Opening 10D18Z9 Manual Extraction of Products of Conception, Retained, Via Natural or Artificial Opening Endoscopic 10E0XZZ Delivery of Products of Conception, External Approach Secondary diagnosis code list for outcome of delivery Z37.0 Single live birth Z37.1 Single stillbirth Z37.2 Twins, both liveborn Z37.3 Twins, one liveborn and one stillborn Z37.4 Twins, both stillborn Z37.50 Multiple births, unspecified, all liveborn Z37.51 Triplets, all liveborn Z37.52 Quadruplets, all liveborn Z37.53 Quintuplets, all liveborn Z37.54 Sextuplets, all liveborn Z37.59 Other multiple births, all liveborn Z37.60 Multiple births, unspecified, some liveborn Z37.61 Triplets, some liveborn Z37.62 Quadruplets, some liveborn Z37.63 Quintuplets, some liveborn Z37.64 Sextuplets, some liveborn Z37.69 Other multiple births, some liveborn Z37.7 Other multiple births, all stillborn Z37.9 Outcome of delivery, unspecified'' We proposed that the three ICD-10-PCS procedure codes listed in the following table would be used to establish the list of codes for the proposed Questionable Obstetric Admission edit logic for cesarean section.

Commenters also supported the list of diagnoses and procedure codes that we proposed to include for the proposed new edit. However, a few commenters expressed concern with several of the procedure codes that were proposed for inclusion under the vaginal delivery procedure code list. Specifically, the commenters identified that ICD-10-PCS procedure codes 10D17Z9 and 10D18Z9 may be reported for other clinical indications, in the absence of an outcome of delivery diagnosis code. Therefore, the commenter stated that the edit would be triggered erroneously for those case scenarios. Response: We appreciate the commenters' support. We reviewed the procedure codes for which the commenters expressed concern under the vaginal delivery procedure code list (ICD-10-PCS procedure codes 10D17Z9 and 10D18Z9) and agree that there may be instances in which the procedure codes could be reported in the absence of an outcome of delivery diagnosis code. Therefore, we believe it is appropriate to remove these two procedure codes from the vaginal delivery procedure code list for the edit. In addition, we reviewed ICD-10-PCS procedure codes 10D07Z6 and 10D07Z8 and believe the procedures could potentially be performed for other clinical indications, in the absence of an outcome of delivery code, and erroneously trigger the proposed edit if reported. After consideration of the public comments we received, we are finalizing our proposal to create the new Questionable Obstetric Admission edit. We also are finalizing our proposal to include ICD-10- PCS procedure codes 10D00Z0, 10D00Z1, and 10D00Z2 listed above for the ``Procedure code list for cesarean section'' portion of the edit. We are finalizing our proposal to include the procedure codes listed above for vaginal delivery with modifications. Specifically, we are not including ICD-10-PCS procedure codes 10D07Z6, 10D07Z87, 10D17Z9 and 10D18Z9 in the ``Procedure code list for vaginal delivery'' portion of the edit and finalizing the inclusion of the remaining [[Page 41227]] procedure codes listed above. In addition, we are finalizing our proposal to include the diagnosis codes listed above under the ``Secondary diagnosis code list for outcome of delivery'' portion of the edit. We are finalizing these changes as described above under the ICD-10 MCE Version 36, effective October 1, 2018. e. Unacceptable Principal Diagnosis Edit In the MCE, there are select codes that describe a circumstance which influences an individual's health status, but does not actually describe a current illness or injury. There also are codes that are not specific manifestations, but may be due to an underlying cause. These codes are considered unacceptable as a principal diagnosis. In limited situations, there are a few codes on the MCE Unacceptable Principal Diagnosis edit code list that are considered ``acceptable'' when a specified secondary diagnosis is also coded and reported on the claim. In the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20234), we noted that, as discussed in section II.F.9. of the preamble of the proposed rule, ICD-10-CM diagnosis codes Z49.02 (Encounter for fitting and adjustment of peritoneal dialysis catheter), Z49.31 (Encounter for adequacy testing for hemodialysis), and Z49.32 (Encounter for adequacy testing for peritoneal dialysis) are currently on the Unacceptable Principal Diagnosis edit code list. We proposed to add diagnosis code Z49.01 (Encounter for fitting and adjustment of extracorporeal dialysis catheter) to the Unacceptable Principal Diagnosis edit code list because this is an encounter code that would more likely be performed in an outpatient setting. Comment: Some commenters supported the proposal to add ICD-10-CM diagnosis code Z49.01 to the Unacceptable Principal Diagnosis edit code list. However, some commenters recommended that CMS reconsider the proposal. These commenters did not dispute the fact that this code is more likely to be reported in the outpatient setting. However, they stated that the proposal to add it to the edit appeared to conflict with the proposal that was discussed in section II.F.9. for MDC 11 (Diseases and Disorders of the Kidney and Urinary Tract) and MS-DRG 685 (Admit for Renal Dialysis). According to the commenters, CMS proposed to only reassign diagnosis code Z49.01 as a principal diagnosis in the proposal to delete MS-DRG 685 and reassign diagnosis code Z49.01 to MS- DRGs 698, 699 and 700. Response: We appreciate the commenters' support. With regard to the commenters who recommended that we reconsider the proposal to add diagnosis code Z49.01 to the Unacceptable Principal Diagnoses edit code list, we believe there is some confusion with respect to the proposal that was discussed in section II.F.9. of the preamble of the proposed rule. The proposal was to reassign diagnosis codes Z49.01, Z49.02, Z49.31 and Z49.32 to MS-DRGs 698, 699 and 700 (Other Kidney and Urinary Tract Diagnoses with MCC, with CC and without CC/MCC, respectively) with the proposed deletion of MS-DRG 685. We are unable to determine what aspect of the proposal that was discussed in section II.F. 9. of the preamble of the proposed rule was unclear. For example, it is not clear if the commenters' confusion relates to the GROUPER logic for MS- DRGs 698, 699, and 700 as shown in the ICD-10 MS-DRG Definitions Manual. As discussed elsewhere in this final rule, in the ICD-10 MS-DRG Definitions Manual, diagnosis codes listed under the heading of ``Principal Diagnosis'' may appear to indicate that those codes are to be reported as a principal diagnosis for assignment to the respective MS-DRG. However, the Definitions Manual display of the GROUPER logic assignment for each diagnosis code is for grouping purposes only and does not correspond to coding guidelines for reporting the principal diagnosis. In other words, cases will group according to the GROUPER logic, regardless of any coding guidelines or coverage policies. It is the MCE and other payer-specific edits that identify inconsistencies in the coding guidelines or coverage policies. We also noted in the proposed rule that, as discussed in section II.F.15. of the preamble of the proposed rule, Table 6C.--Invalid Diagnosis Codes associated with the proposed rule (which is available via the internet on the CMS website at: http://www.cms.hhs.gov/Medicare/Medicare-Fee-for-Service-Payment/AcuteInpatientPPS/index.html) listed the diagnosis codes that will no longer be effective as of October 1, 2018. As previously noted, included in this table is an ICD- 10-CM diagnosis code Z13.4 (Encounter for screening for certain developmental disorders in childhood) which is currently listed on the Unacceptable Principal Diagnoses edit code list. We proposed to remove this code from the Unacceptable Principal Diagnosis edit code list. We also proposed to continue to include the other existing diagnosis codes currently listed under the Unacceptable Principal Diagnosis edit code list. Comment: Commenters supported the proposal to remove ICD-10-CM diagnosis code Z13.4 from the Unacceptable Principal diagnoses category edit code list because it will be an invalid code effective October 1, 2018. Response: We appreciate the commenters' support. After consideration of the public comments we received, we are finalizing our proposal to add ICD-10-CM diagnosis code Z49.01 to the Unacceptable Principal Diagnosis edit code list. We also are finalizing our proposal to remove ICD-10-CM diagnosis code Z13.4 from the Unacceptable Principal Diagnosis edit code list. In addition, we are finalizing our proposal to maintain the other existing codes on the Unacceptable Principal Diagnosis edit code list under the ICD-10 MCE Version 36, effective October 1, 2018. Comment: One commenter requested that CMS review a coverage edit in the MCE manual and software. According to the commenter, CMS began covering multiple myeloma on January 1, 2016 under the condition of coverage with evidence development (CED) as shown in guidance located at: https://www.cms.gov/Medicare/Coverage/Coverage-with-Evidence-Development/allo-MM.html. The commenter noted that the applicable procedure codes along with diagnosis codes C90.00 (Multiple myeloma not having achieved remission) and C90.01 (Multiple myeloma in remission) are listed as ``non-covered'' in the MCE manual and encouraged CMS to review further and make any necessary updates as needed to ensure claims are processed appropriately. Response: We thank the commenter for bringing this to our attention. Upon review, guidance was issued on January 27, 2016 for allogeneic hematopoietic stem cell transplant (HSCT) for certain Medicare beneficiaries with multiple myeloma under CED. This guidance is available via the internet on the CMS website at: https://www.cms.gov/Medicare/Coverage/Coverage-with-Evidence-Development/allo-MM.html. We agree with the commenter and, therefore, are removing the following noncovered procedure edit from the ICD-10 MCE Version 36 manual, effective October 1, 2018: ``E. Non-covered procedure codes The procedures shown below are identified as non-covered procedures only when any code from the diagnoses list shown below is present as either a principal or secondary diagnosis.

Future Enhancement In the FY 2018 IPPS/LTCH PPS final rule (82 FR 38053 through 38054), we noted the importance of ensuring accuracy of the coded data from the reporting, collection, processing, coverage, payment, and analysis aspects. We have engaged a contractor to assist in the review of the limited coverage and noncovered procedure edits in the MCE that may also be present in other claims processing systems that are utilized by our MACs. The MACs must adhere to criteria specified within the National Coverage Determinations (NCDs) and may implement their own edits in addition to what are already incorporated into the MCE, resulting in duplicate edits. The objective of this review is to identify where duplicate edits may exist and to determine what the impact might be if these edits were to be removed from the MCE. We have noted that the purpose of the MCE is to ensure that errors and inconsistencies in the coded data are recognized during Medicare claims processing. In the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20235), we indicated that we are considering whether the inclusion of coverage edits in the MCE necessarily aligns with that specific goal because the focus of coverage edits is on whether or not a particular service is covered for payment purposes and not whether it was coded correctly. As we continue to evaluate the purpose and function of the MCE with respect to ICD-10, we encourage public input for future discussion. As we discussed in the FY 2018 IPPS/LTCH PPS final rule, we recognize a need to further examine the current list of edits and the definitions of those edits. We continue to encourage public comments on whether there are additional concerns with the current edits, including specific edits or language that should be removed or revised, edits that should be combined, or new edits that should be added to assist in detecting errors or inaccuracies in the coded data. Comments should be directed to the MS-DRG Classification Change Mailbox located at: [email protected] by November 1, 2018 for FY 2020. 14. Changes to Surgical Hierarchies Some inpatient stays entail multiple surgical procedures, each one of which, occurring by itself, could result in assignment of the case to a different MS-DRG within the MDC to which the principal diagnosis is assigned. Therefore, it is necessary to have a decision rule within the GROUPER by which these cases are assigned to a single MS-DRG. The surgical hierarchy, an ordering of surgical classes from most resource- intensive to least resource-intensive, performs that function. Application of this hierarchy ensures that cases involving multiple surgical procedures are assigned to the MS-DRG associated with the most resource-intensive surgical class. A surgical class can be composed of one or more MS-DRGs. For example, in MDC 11, the surgical class ``kidney transplant'' consists of a single MS-DRG (MS-DRG 652) and the class ``major bladder procedures'' consists of three MS-DRGs (MS-DRGs 653, 654, and 655). Consequently, in many cases, the surgical hierarchy has an impact on more than one MS-DRG. The methodology for determining the most resource-intensive surgical class involves weighting the average resources for each MS-DRG by frequency to determine the weighted average resources for each surgical class. For example, assume surgical class A includes MS-DRGs 001 and 002 and surgical class B includes MS- DRGs 003, 004, and 005. Assume also that the average costs of MS-DRG 001 are higher than that of MS-DRG 003, but the average costs of MS- DRGs 004 and 005 are higher than the average costs of MS-DRG 002. To determine whether surgical class A should be higher or lower than surgical class B in the surgical hierarchy, we would weigh the average costs of each MS-DRG in the class by frequency (that is, by the number of cases in the MS-DRG) to determine average resource consumption for the surgical class. The surgical classes would then be ordered from the class with the highest average resource utilization to that with the lowest, with the exception of ``other O.R. procedures'' as discussed in this final rule. This methodology may occasionally result in assignment of a case involving multiple procedures to the lower-weighted MS-DRG (in the highest, most resource-intensive surgical class) of the available alternatives. However, given that the logic underlying the surgical hierarchy provides that the GROUPER search for the procedure in the most resource-intensive surgical class, in [[Page 41229]] cases involving multiple procedures, this result is sometimes unavoidable. We note that, notwithstanding the foregoing discussion, there are a few instances when a surgical class with a lower average cost is ordered above a surgical class with a higher average cost. For example, the ``other O.R. procedures'' surgical class is uniformly ordered last in the surgical hierarchy of each MDC in which it occurs, regardless of the fact that the average costs for the MS-DRG or MS-DRGs in that surgical class may be higher than those for other surgical classes in the MDC. The ``other O.R. procedures'' class is a group of procedures that are only infrequently related to the diagnoses in the MDC, but are still occasionally performed on patients with cases assigned to the MDC with these diagnoses. Therefore, assignment to these surgical classes should only occur if no other surgical class more closely related to the diagnoses in the MDC is appropriate. A second example occurs when the difference between the average costs for two surgical classes is very small. We have found that small differences generally do not warrant reordering of the hierarchy because, as a result of reassigning cases on the basis of the hierarchy change, the average costs are likely to shift such that the higher- ordered surgical class has lower average costs than the class ordered below it. Based on the changes that we proposed to make in the FY 2019 IPPS/ LTCH PPS proposed rule, as discussed in section II.F.10. of the preamble of this final rule, in the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20235), we proposed to revise the surgical hierarchy for MDC 14 (Pregnancy, Childbirth & the Puerperium) as follows: In MDC 14, we proposed to delete MS-DRGs 765 and 766 (Cesarean Section with and without CC/MCC, respectively) and MS-DRG 767 (Vaginal Delivery with Sterilization and/or D&C) from the surgical hierarchy. We proposed to sequence proposed new MS-DRGs 783, 784, and 785 (Cesarean Section with Sterilization with MCC, with CC and without CC/MCC, respectively) above proposed new MS-DRGs 786, 787, and 788 (Cesarean Section without Sterilization with MCC, with CC and without CC/MCC, respectively). We proposed to sequence proposed new MS-DRGs 786, 787, and 788 (Cesarean Section without Sterilization with MCC, with CC and without CC/MCC, respectively) above MS-DRG 768 (Vaginal Delivery with O.R. Procedure Except Sterilization and/or D&C). We also proposed to sequence proposed new MS-DRGs 796, 797, and 798 (Vaginal Delivery with Sterilization/D&C with MCC, with CC and without CC/MCC, respectively) below MS-DRG 768 and above MS-DRG 770 (Abortion with D&C, Aspiration Curettage or Hysterotomy). Finally, we proposed to sequence proposed new MS-DRGs 817, 818, and 819 (Other Antepartum Diagnoses with O.R. procedure with MCC, with CC and without CC/MCC, respectively) below MS-DRG 770 and above MS-DRG 769 (Postpartum and Post Abortion Diagnoses with O.R. Procedure). Our proposals for Appendix D MS-DRG Surgical Hierarchy by MDC and MS-DRG of the ICD-10 MS-DRG Definitions Manual Version 36 are illustrated in the following table. Proposed Surgical Hierarchy: MDC 14 [Pregnancy, childbirth and the puerperium] ------------------------------------------------------------------------ ------------------------------------------------------------------------ Proposed New MS-DRGs 783-785........... Cesarean Section with Sterilization. Proposed New MS-DRGs 786-788........... Cesarean Section without Sterilization. MS-DRG 768............................. Vaginal Delivery with O.R. Procedures. Proposed New MS-DRGs 796-798........... Vaginal Delivery with Sterilization/D&C. MS-DRG 770............................. Abortion with D&C, Aspiration Curettage or Hysterotomy. Proposed New MS-DRGs 817-819........... Other Antepartum Diagnoses with O.R. Procedure. MS-DRG 769............................. Postpartum and Post Abortion Diagnoses with O.R. Procedure. ------------------------------------------------------------------------ Comment: Commenters supported the proposed additions, deletions, and sequencing for the surgical hierarchy under MDC 14. Response: We appreciate the commenters' support. After consideration of the public comments we received, we are finalizing our proposed changes to Appendix D MS-DRG Surgical Hierarchy by MDC and MS-DRG of the ICD-10 MS-DRG Definitions Manual Version 36 as illustrated in the table above effective October 1, 2018. As with other MS-DRG related issues, we encourage commenters to submit requests to examine ICD-10 claims pertaining to the surgical hierarchy via the CMS MS-DRG Classification Change Request Mailbox located at: [email protected] by November 1, 2018 for FY 2020 consideration. 15. Changes to the MS-DRG Diagnosis Codes for FY 2019 a. Background of the CC List and the CC Exclusions List Under the IPPS MS-DRG classification system, we have developed a standard list of diagnoses that are considered CCs. Historically, we developed this list using physician panels that classified each diagnosis code based on whether the diagnosis, when present as a secondary condition, would be considered a substantial complication or comorbidity. A substantial complication or comorbidity was defined as a condition that, because of its presence with a specific principal diagnosis, would cause an increase in the length-of-stay by at least 1 day in at least 75 percent of the patients. However, depending on the principal diagnosis of the patient, some diagnoses on the basic list of complications and comorbidities may be excluded if they are closely related to the principal diagnosis. In FY 2008, we evaluated each diagnosis code to determine its impact on resource use and to determine the most appropriate CC subclassification (non-CC, CC, or MCC) assignment. We refer readers to sections II.D.2. and 3. of the preamble of the FY 2008 IPPS final rule with comment period for a discussion of the refinement of CCs in relation to the MS-DRGs we adopted for FY 2008 (72 FR 47152 through 47171). b. Additions and Deletions to the Diagnosis Code Severity Levels for FY 2019 In the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20236), we indicated that the following tables identifying the proposed additions and deletions to the MCC severity levels list and the proposed additions and deletions to the CC severity levels list for FY 2019 were available via the internet on the CMS website at: https://www.cms.gov/Medicare/Medicare-Fee-for-Service-Payment/AcuteInpatientPPS/index.html. [[Page 41230]] Table 6I.1--Proposed Additions to the MCC List--FY 2019; Table 6I.2--Proposed Deletions to the MCC List--FY 2019; Table 6J.1--Proposed Additions to the CC List--FY 2019; and Table 6J.2--Proposed Deletions to the CC List--FY 2019. We invited public comments on our proposed severity level designations for the diagnosis codes listed in Table 6I.1. and Table 6J.1. We noted that, for Table 6I.2. and Table 6J.2., the proposed deletions are a result of code expansions, with the exception of diagnosis codes B20 and J80, which are the result of proposed severity level designation changes. Therefore, the diagnosis codes on these lists will no longer be valid codes, effective FY 2019. We referred readers to the Tables 6I.1, 6I.2, 6J.1, and 6J.2 associated with the proposed rule, which are available via the internet on the CMS website at: https://www.cms.gov/Medicare/Medicare-Fee-for-Service-Payment/AcuteInpatientPPS/index.html. Comment: Commenters supported the proposed additions and deletions for the diagnosis codes, and their corresponding severity level designations that were listed in Tables 6I.1, 6I.2, 6J.1, and 6J.2. associated with the FY 2019 IPPS/LTCH PPS proposed rule. However, a few commenters expressed concern with the proposed severity level designation change to diagnosis code B20, and recommended CMS conduct further analysis prior to finalizing any proposals. Response: We appreciate the commenters' support. We refer readers to section II.F.16.b. of the preamble of this final rule for the detailed discussion of public comments related to the proposals and final statement of policy involving diagnosis codes B20 and J80. Comment: One commenter disagreed with CMS' proposal to designate diagnosis codes K35.20 (Acute appendicitis with generalized peritonitis, without abscess) and T81.44XA (Sepsis following a procedure, initial encounter) as CC severity levels, and recommended CMS reconsider the conditions and classify the severity levels as MCCs. The commenter noted that the predecessor code for diagnosis code K35.20 is diagnosis code K35.2 (Acute appendicitis with generalized peritonitis), which is classified as a MCC severity level designation. Therefore, the commenter also believed that diagnosis code K35.20 should be designated as a MCC severity level. Additionally, the commenter stated that diagnosis code T81.44XA should be classified as an MCC severity level because sepsis is defined as a life-threatening organ dysfunction caused by a host response to infection. Response: While we acknowledge that our process in assigning a severity level designation for a diagnosis code generally begins with identifying the designation of the predecessor code assignment, we believe that any new or revised clinical concepts included in the new diagnosis codes should also be considered when making a severity level designation. We reviewed diagnosis codes K35.20 and T81.44XA and our clinical advisors continue to support the CC severity level designation of these diagnosis codes. The commenter is correct that, effective October 1, 2018, diagnosis code K35.20 has been expanded from the current diagnosis code K35.2. However, we also note that, effective October 1, 2018, diagnosis code K35.2 has been expanded to create new diagnosis code K35.21 (Acute appendicitis with generalized peritonitis, with abscess). In addition, effective October 1, 2018, diagnosis code K35.3 (Acute appendicitis with localized peritonitis) has been expanded to create new diagnosis codes K35.30 (Acute appendicitis with localized peritonitis, without perforation or gangrene), K35.31 (Acute appendicitis with localized peritonitis and gangrene, without perforation), K35.32 (Acute appendicitis with perforation and localized peritonitis, without abscess) and K35.33 (Acute appendicitis with perforation and localized peritonitis, with abscess). Consistent with our usual process, in reviewing all of these newly expanded conditions, our clinical advisors considered the additional clinical concepts now included with each diagnosis code in evaluating the appropriate proposed severity level assignments. Our clinical advisors believed that the new diagnosis codes for acute appendicitis described as ``with abscess'' or ``with perforation'' were clinically qualified for the MCC severity level designation, while acute appendicitis ``without abscess'' or ``without perforation'' were clinically qualified for the CC severity level designation because cases with abscess or perforation would be expected to require more clinical resources and time to treat while those cases ``without abscess'' or ``without perforation'' are not as severe clinical conditions. As such, we disagree with the commenter that, based on the designation of its predecessor code alone, diagnosis code K35.20 should be designated as an MCC severity level instead of a CC for FY 2019. With regard to diagnosis code T81.44XA, our clinical advisors maintain that a CC severity level designation is most appropriate because the new code is clinically consistent with the predecessor code, T81.4XXA (Infection following a procedure, initial encounter), which also has a CC severity level designation. Currently, under Version 35 of the ICD-10 MS-DRGs, diagnosis code T81.4XXA contains several inclusion terms (conditions for which the code may be reported), one of which is ``sepsis following a procedure''. Our clinical advisors do not believe that the creation of a unique diagnosis code to specifically identify this condition within the classification introduces a new clinical concept requiring a higher level of resources. The new diagnosis code provides additional detail as to the type of infection following a procedure. However, it is considered to be clinically similar to the current diagnosis code describing an infection following a procedure. We also note that an additional five new diagnosis codes describing infections of varying degrees following a procedure were created for FY 2019 based on the other inclusion terms that currently exist at diagnosis code T81.4XXA. As shown in the table below and in Table 6J.1. associated with the proposed rule, a total of six new diagnosis codes were proposed to be designated at the CC severity level based on review of the predecessor code (T81.4XXA), clinical coherence, and resource considerations. ------------------------------------------------------------------------ ICD-10-CM code Code description ------------------------------------------------------------------------ T81.40XA.................. Infection following a procedure, unspecified, initial encounter. T81.41XA.................. Infection following a procedure, superficial incisional surgical site, initial encounter. T81.42XA.................. Infection following a procedure, deep incisional surgical site, initial encounter. T81.43XA.................. Infection following a procedure, organ and space surgical site, initial encounter. T81.44XA.................. Sepsis following a procedure, initial encounter. T81.49XA.................. Infection following a procedure, other surgical site, initial encounter. ------------------------------------------------------------------------ [[Page 41231]] Therefore, for the reasons discussed above, our clinical advisors continue to support the proposed CC severity level designation for diagnosis code T81.44XA for FY 2019. In addition, because these diagnosis codes identified by the commenter are new, we do not have any claims data for further analysis. Once we have additional claims data to allow us to conduct further review, we can continue to examine these conditions to determine if their impact on resource use is equal to or above the expected value of a CC severity level designation. After consideration of the public comments we received, we are finalizing our proposal to designate diagnosis codes K35.20 and T81.44XA as CC severity levels. We also are finalizing our other proposed additions and deletions with their corresponding severity level designations for FY 2019. We refer readers to Tables 6I.1., 6I.2, 6J.1, and 6J.2. associated with this final rule, which are available via the internet on the CMS website at: https://www.cms.gov/Medicare/Medicare-Fee-for-Service-Payment/AcuteInpatientPPS/index.html. c. Principal Diagnosis Is Its Own CC or MCC In the FY 2018 IPPS/LTCH PPS final rule (82 FR 38060), we provided the public with notice of our plans to conduct a comprehensive review of the CC and MCC lists for FY 2019. In the FY 2018 IPPS/LTCH PPS final rule (82 FR 38056 through 38057), we also finalized our proposal to maintain the existing lists of principal diagnosis codes in Table 6L.-- Principal Diagnosis Is Its Own MCC List and Table 6M.--Principal Diagnosis Is Its Own CC List for FY 2018, without any changes to the existing lists, noting our plans to conduct a comprehensive review of the CC and MCC lists for FY 2019 (82 FR 38060). We stated that having multiple lists for CC and MCC diagnoses when reported as a principal and/or secondary diagnosis may not provide an accurate representation of resource utilization for the MS-DRGs. We also stated that the purpose of the Principal Diagnosis Is Its Own CC or MCC Lists was to ensure consistent MS-DRG assignment between the ICD-9-CM and ICD-10 MS-DRGs. The Principal Diagnosis Is Its Own CC or MCC Lists were developed for the FY 2016 implementation of the ICD- 10 version of the MS-DRGs to facilitate replication of the ICD-9-CM MS- DRGs. As part of our efforts to replicate the ICD-9-CM MS-DRGs, we implemented logic that may have increased the complexity of the MS-DRG assignment hierarchy and altered the format of the ICD-10 MS-DRG Definitions Manual. Two examples of workarounds used to facilitate replication are the proliferation of procedure clusters in the surgical MS-DRGs and the creation of the Principal Diagnosis Is Its Own CC or MCC Lists special logic. The following paragraph was added to the Version 33 ICD-10 MS-DRG Definitions Manual to explain the use of the Principal Diagnosis Is Its Own CC or MCC Lists: ``A few ICD-10-CM diagnosis codes express conditions that are normally coded in ICD-9-CM using two or more ICD-9- CM diagnosis codes. In the interest of ensuring that the ICD-10 MS-DRGs Version 33 places a patient in the same DRG regardless whether the patient record were to be coded in ICD-9-CM or ICD-10-CM/PCS, whenever one of these ICD-10-CM combination codes is used as principal diagnosis, the cluster of ICD-9-CM codes that would be coded on an ICD- 9-CM record is considered. If one of the ICD-9-CM codes in the cluster is a CC or MCC, then the single ICD-10-CM combination code used as a principal diagnosis must also imply the CC or MCC that the ICD-9-CM cluster would have presented. The ICD-10-CM diagnoses for which this implication must be made are listed here.'' Versions 34 and 35 of the ICD-10 MS-DRG Definitions Manual also include this special logic for the MS-DRGs. The Principal Diagnosis Is Its Own CC or MCC Lists were developed in the absence of ICD-10 coded data by mapping the ICD-9-CM diagnosis codes to the new ICD-10-CM combination codes. CMS has historically used clinical judgment combined with data analysis to assign a principal diagnosis describing a complex or severe condition to the appropriate DRG or MS-DRG. The initial ICD-10 version of the MS-DRGs replicated from the ICD-9 version can now be evaluated using clinical judgment combined with ICD-10 coded data because it is no longer necessary to replicate MS-DRG assignment across the ICD-9 and ICD-10 versions of the MS-DRGs for purposes of calculating relative weights. Now that ICD-10 coded data are available, in addition to using the data for calculating relative weights, ICD-10 data can be used to evaluate the effectiveness of the special logic for assigning a severity level to a principal diagnosis, as an indicator of resource utilization. In the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20237), to evaluate the effectiveness of the special logic, we conducted analysis of the ICD-10 coded data combined with clinical review to determine whether to propose to keep the special logic for assigning a severity level to a principal diagnosis, or to propose to remove the special logic and use other available means of assigning a complex principal diagnosis to the appropriate MS-DRG. In the proposed rule, using claims data from the September 2017 update of the FY 2017 MedPAR file, we employed the following method to determine the impact of removing the special logic used in the current Version 35 GROUPER to process claims containing a code on the Principal Diagnosis Is Its Own CC or MCC Lists. Edits and cost estimations used for relative weight calculations were applied, resulting in 9,070,073 IPPS claims analyzed for this special logic impact evaluation. We refer readers to section II.G. of the preamble of this final rule for further information regarding the methodology for calculation of the relative weights. First, we identified the number of cases potentially impacted by the special logic. We identified 310,184 cases reporting a principal diagnosis on the Principal Diagnosis Is Its Own CC or MCC lists. Of the 310,184 total cases that reported a principal diagnosis code on the Principal Diagnosis Is Its Own CC or MCC Lists, 204,749 cases also reported a secondary diagnosis code at the same severity level or higher severity level, and therefore the special logic had no impact on MS-DRG assignment. However, of the 310,184 total cases, there were 105,435 cases that did not report a secondary diagnosis code at the same severity level or higher severity level, and therefore the special logic could potentially impact MS-DRG assignment, depending on the specific severity leveling structure of the base DRG. Next, we removed the special logic in the GROUPER that is used for processing claims reporting a principal diagnosis on the Principal Diagnosis Is Its Own CC or MCC Lists, thereby creating a Modified Version 35 GROUPER. Using this Modified Version 35 GROUPER, we reprocessed the 105,435 claims for which the principal diagnosis code was the sole source of a MCC or CC on the case, to obtain data for comparison showing the effect of removing the special logic. After removing the special logic in the Version 35 GROUPER for processing claims containing diagnosis codes on the Principal Diagnosis Is Its Own CC or MCC Lists, and reprocessing the claims using the Modified Version 35 GROUPER software, we found that 18,596 (6 percent) of the 310,184 cases reporting a principal diagnosis on the Principal Diagnosis Is Its Own CC or MCC Lists resulted in a different MS- [[Page 41232]] DRG assignment. Overall, the number of claims impacted by removal of the special logic (18,596) represents 0.2 percent of the 9,070,073 IPPS claims analyzed. Below we provide a summary of the steps that we followed for the analysis performed. Step 1. We analyzed 9,070,073 claims to determine the number of cases impacted by the special logic. With Special Logic--9,070,073 Claims Analyzed ------------------------------------------------------------------------ ------------------------------------------------------------------------ Number of cases reporting a principal diagnosis from the 310,184 Principal Diagnosis Is Its Own CC/MCC lists (special logic)................................................. Number of cases reporting an additional CC/MCC secondary 204,749 diagnosis code at or above the level of the designated severity level of the principal diagnosis.............. Number of cases not reporting an additional CC/MCC 105,435 secondary diagnosis code............................... ------------------------------------------------------------------------ Step 2. We removed special logic from GROUPER and created a modified GROUPER. Step 3. We reprocessed 105,435 claims with modified GROUPER. Without Special Logic--105,435 Claims Analyzed ------------------------------------------------------------------------ ------------------------------------------------------------------------ Number of cases reporting a principal diagnosis from the 310,184 Principal Diagnosis Is Its Own CC/MCC lists............ Number of cases resulting in different MS-DRG assignment 18,596 ------------------------------------------------------------------------ To estimate the overall financial impact of removing the special logic from the GROUPER, we calculated the aggregate change in estimated payment for the MS-DRGs by comparing average costs for each MS-DRG affected by the change, before and after removing the special logic. Before removing the special logic in the Version 35 GROUPER, the cases impacted by the special logic had an estimated average payment of $58 million above the average costs for all the MS-DRGs to which the claim was originally assigned. After removing the special logic in the Version 35 GROUPER, the 18,596 cases impacted by the special logic had an estimated average payment of $39 million below the average costs for the newly assigned MS-DRGs. We performed regression analysis to compare the proportion of variance in the MS-DRGs with and without the special logic. The results of the regression analysis showed a slight decrease in variance when the logic was removed. While the decrease itself was not statistically significant (an R-squared of 36.2603 percent after the special logic was removed, compared with an R-squared of 36.2501 percent in the current version 35 GROUPER), we note that the proportion of variance across the MS-DRGs essentially stayed the same, and certainly did not increase, when the special logic was removed. We further examined the 18,596 claims that were impacted by the special logic in the GROUPER for processing claims containing a code on the Principal Diagnosis Is Its Own CC or MCC Lists. The 18,596 claims were analyzed by the principal diagnosis code and the MS-DRG assigned, resulting in 588 principal diagnosis and MS-DRG combinations or subsets. Of the 588 subsets of cases that utilized the special logic, 556 of the 588 subsets (95 percent) had fewer than 100 cases, 529 of the 588 subsets (90 percent) had fewer than 50 cases, and 489 of the 588 subsets (83 percent) had fewer than 25 cases. We examined the 32 subsets of cases (5 percent of the 588 subsets) that utilized the special logic and had 100 or more cases. Of the 32 subsets of cases, 18 (56 percent) are similar in terms of average costs and length of stay to the MS-DRG assignment that results when the special logic is removed, and 14 of the 32 subsets of cases (44 percent) are similar in terms of average costs and length of stay to the MS-DRG assignment that results when the special logic is utilized. The table below contains examples of four subsets of cases that utilize the special logic, comparing average length of stay and average costs between two MS-DRGs within a base DRG, corresponding to the MS- DRG assigned when the special logic is removed and the MS-DRG assigned when the special logic is utilized. All four subsets of cases involve the principal diagnosis code E11.52 (Type 2 diabetes mellitus with diabetic peripheral angiopathy with gangrene). There are four subsets of cases in this example because the records involving the principal diagnosis code E11.52 are assigned to four different base DRGs, one medical MS-DRG and three surgical MS-DRGs, depending on the procedure code(s) reported on the claim. All subsets of cases contain more than 100 claims. In three of the four subsets, the cases are similar in terms of average length of stay and average costs to the MS-DRG assignment that results when the special logic is removed, and in one of the four subsets, the cases are similar in terms of average length of stay and average costs to the MS-DRG assignment that results when the special logic is utilized. As shown in the following table, using ICD-10-CM diagnosis code E11.52 (Type 2 diabetes mellitus with diabetic peripheral angiopathy with gangrene) as our example, the data findings show four different MS-DRG pairs for which code E11.52 was the principal diagnosis on the claim and where the special logic impacted MS-DRG assignment. For the first MS-DRG pair, we examined MS-DRGs 240 and 241 (Amputation for Circulatory System Disorders Except Upper Limb and Toe with CC and without CC/MCC, respectively). We found 436 cases reporting diagnosis code E11.52 as the principal diagnosis, with an average length of stay of 5.5 days and average costs of $11,769. These 436 cases are assigned to MS-DRG 240 with the special logic utilized, and assigned to MS-DRG 241 with the special logic removed. The total number of cases reported in MS-DRG 240 was 7,675, with an average length of stay of 8.3 days and average costs of $17,876. The total number of cases reported in MS-DRG 241 was 778, with an average length of stay of 5.0 days and average costs of $10,882. The 436 cases are more similar to MS-DRG 241 in terms of length of stay and average cost and less similar to MS-DRG 240. For the second MS-DRG pair, we examined MS-DRGs 256 and 257 (Upper Limb and Toe Amputation for Circulatory System Disorders with CC and without CC/MCC, respectively). We found 193 cases reporting ICD-10-CM [[Page 41233]] diagnosis code E11.52 as the principal diagnosis, with an average length of stay of 4.2 days and average costs of $8,478. These 193 cases are assigned to MS-DRG 256 with the special logic utilized, and assigned to MS-DRG 257 with the special logic removed. The total number of cases reported in MS-DRG 256 was 2,251, with an average length of stay of 6.1 days and average costs of $11,987. The total number of cases reported in MS-DRG 257 was 115, with an average length of stay of 4.6 days and average costs of $7,794. These 193 cases are more similar to MS-DRG 257 in terms of average length of stay and average costs and less similar to MS-DRG 256. For the third MS-DRG pair, we examined MS-DRGs 300 and 301 (Peripheral Vascular Disorders with CC and without CC/MCC, respectively). We found 185 cases reporting ICD-10-CM diagnosis code E11.52 as the principal diagnosis, with an average length of stay of 3.6 days and average costs of $5,981. These 185 cases are assigned to MS-DRG 300 with the special logic utilized, and assigned to MS-DRG 301 with the special logic removed. The total number of cases reported in MS-DRG 300 was 29,327, with an average length of stay of 4.1 days and average costs of $7,272. The total number of cases reported in MS-DRG 301 was 9,611, with an average length of stay of 2.8 days and average costs of $5,263. These 185 cases are more similar to MS-DRG 301 in terms of average length of stay and average costs and less similar to MS-DRG 300. For the fourth MS-DRG pair, we examined MS-DRGs 253 and 254 (Other Vascular Procedures with CC and without CC/MCC, respectively). We found 225 cases reporting diagnosis code E11.52 as the principal diagnosis, with an average length of stay of 5.2 days and average costs of $17,901. These 225 cases are assigned to MS-DRG 253 with the special logic utilized, and assigned to MS-DRG 254 with the special logic removed. The total number of cases reported in MS-DRG 253 was 25,714, with an average length of stay of 5.4 days and average costs of $18,986. The total number of cases reported in MS-DRG 254 was 12,344, with an average length of stay of 2.8 days and average costs of $13,287. Unlike the previous three MS-DRG pairs, these 225 cases are more similar to MS-DRG 253 in terms of average length of stay and average costs and less similar to MS-DRG 254.

As stated in the proposed rule and earlier in this discussion, it is no longer necessary to replicate MS-DRG assignment across the ICD-9 and ICD-10 versions of the MS-DRGs. The available ICD-10 data can now be used to evaluate other indicators of resource utilization. Therefore, as an initial recommendation from the first phase in our comprehensive review of the CC and MCC lists, we proposed to remove the special logic in the GROUPER for processing claims containing a diagnosis code from the Principal Diagnosis Is Its Own CC or MCC Lists, and we proposed to delete the tables containing the lists of principal diagnosis codes, Table 6L.--Principal Diagnosis Is Its Own MCC List and Table 6M.--Principal Diagnosis Is Its Own CC List, from the ICD-10 MS- DRG Definitions Manual for FY 2019. We invited public comments on our proposals. Comment: Commenters supported the proposed deletion of the Principal Diagnosis Is Its Own CC or MCC logic. One commenter stated that the lists were created to facilitate replication of the ICD-9 based MS-DRGs and are an artifact of the ICD-10 transitions. Another commenter recommended removing some of the conditions that are currently on the lists but expressed concern that eliminating the logic completely could impact the ability to measure a patient's severity of illness. One commenter noted that CMS described its internal comprehensive review and analysis that were conducted, which provided some level of insight for the proposal; however, the overarching comment was that CMS believed there were more effective indicators of resource utilization. Other commenters disagreed with CMS' proposal to ``globally'' remove the Principal Diagnosis Is Its Own CC or MCC logic. A few commenters stated that a more detailed analysis, consistent with the comprehensive CC/MCC analysis approach conducted for severity level changes, should occur. One commenter recommended that the logic described as part of the MS-DRG Conversion Project with the MCC and CC translations from ICD-9 to ICD-10 be considered. Another commenter acknowledged that CMS is no longer attempting to replicate the ICD-9 based MS-DRG GROUPER logic. However, this commenter noted that the conditions represented by the ICD-10-CM combination codes are clinically the [[Page 41234]] same conditions that were CCs or MCCs under ICD-9-CM. Response: We appreciate the commenters' support. With regard to the commenter who recommended removing some of the conditions that are currently on the lists but expressed concern that eliminating the logic completely could impact the ability to measure a patient's severity of illness, we disagree because, in general, the description of a diagnosis code itself describes or implies a certain level of severity. In addition, there are other factors to consider besides the principal diagnosis when determining severity of illness and resource utilization. In response to the other commenters who disagreed with our proposal to remove the Principal Diagnosis Is Its Own CC or MCC logic and recommended that we perform an analysis consistent with the comprehensive CC/MCC analysis, we note that such an analysis would not be conclusive because the purpose of the comprehensive CC/MCC analysis is to evaluate the impact in resource use for patients with conditions reported as secondary diagnoses. We believe that the analysis that was performed and discussed in the proposed rule was appropriate for assessing if we should maintain the special logic that currently exists for assigning a severity level to a principal diagnosis, as well as to assess whether it would be appropriate to propose removing the special logic and utilize alternate methods to evaluate what should be considered a complex principal diagnosis for MS-DRG assignment purposes. As stated in the proposed rule (83 FR 20237), CMS has historically used clinical judgment combined with data analysis to assign a principal diagnosis describing a complex or severe condition to the appropriate MS-DRG. We also note that, as stated in the proposed rule (83 FR 20238), the findings from our analysis of the 18,596 claims that were impacted by the special logic in the GROUPER for processing claims containing a code on the Principal Diagnosis Is Its Own CC or MCC Lists demonstrated that 556 of the 588 subsets had fewer than 100 cases. The low number of cases means that if the special logic had been proposed for the first time under ICD-10, 95 percent of the diagnosis codes that were responsible for 95 percent of the cases using the special logic would not have met the criteria for proposing a change to their severity level. With regard to the commenter who stated that the conditions represented by the ICD-10-CM combination codes are clinically the same conditions that were CCs or MCCs under ICD-9-CM, we note that combination diagnosis codes are a feature of the classification of both ICD-9-CM and ICD-10-CM. The majority of the combination diagnosis codes in ICD-9-CM are also combination codes in ICD-10-CM. The current list of ICD-10-CM codes that are included in the special logic is a result of the fact that the codes were classified differently in ICD-9-CM than in ICD-10-CM. Diagnoses represented as two separate codes under ICD-9-CM were represented in a combination code under ICD-10-CM. Codes that were combination codes in both ICD-9-CM and ICD-10-CM do not have any special severity logic applied, regardless of the clinical severity of the conditions described, or the increased use of resources that could be associated with a particular combination principal diagnosis. As a result, the categorization of ICD-10-CM codes into lists wherein the principal diagnosis is its own CC or MCC is based not on a systematic clinical evaluation of the severity of illness of patients with these combination diagnosis codes, or on a systematic evaluation of data containing these combination diagnosis codes used as principal diagnosis, but on a collection of codes selected exclusively because there were structural differences between the classification scheme in ICD-9-CM versus ICD-10-CM. Now that ICD-10 coded data are available, it can be used to evaluate other indicators of resource utilization, along with clinical judgment. After consideration of the public comments we received, we are finalizing our proposal to remove the special logic in the GROUPER for processing claims containing a code on the Principal Diagnosis Is Its Own CC or MCC Lists as an initial step in our first phase of the comprehensive review of the CC and MCC lists. We also are finalizing our proposal to delete the tables containing the lists of principal diagnosis codes, Table 6L.--Principal Diagnosis Is Its Own MCC List and Table 6M.--Principal Diagnosis Is Its Own CC List, from the ICD-10 MS- DRG Definitions Manual Version 36, effective October 1, 2018. d. CC Exclusions List for FY 2019 In the September 1, 1987 final notice (52 FR 33143) concerning changes to the DRG classification system, we modified the GROUPER logic so that certain diagnoses included on the standard list of CCs would not be considered valid CCs in combination with a particular principal diagnosis. We created the CC Exclusions List for the following reasons: (1) To preclude coding of CCs for closely related conditions; (2) to preclude duplicative or inconsistent coding from being treated as CCs; and (3) to ensure that cases are appropriately classified between the complicated and uncomplicated DRGs in a pair. In the May 19, 1987 proposed notice (52 FR 18877) and the September 1, 1987 final notice (52 FR 33154), we explained that the excluded secondary diagnoses were established using the following five principles: Chronic and acute manifestations of the same condition should not be considered CCs for one another; Specific and nonspecific (that is, not otherwise specified (NOS)) diagnosis codes for the same condition should not be considered CCs for one another; Codes for the same condition that cannot coexist, such as partial/total, unilateral/bilateral, obstructed/unobstructed, and benign/malignant, should not be considered CCs for one another; Codes for the same condition in anatomically proximal sites should not be considered CCs for one another; and Closely related conditions should not be considered CCs for one another. The creation of the CC Exclusions List was a major project involving hundreds of codes. We have continued to review the remaining CCs to identify additional exclusions and to remove diagnoses from the master list that have been shown not to meet the definition of a CC. We refer readers to the FY 2014 IPPS/LTCH PPS final rule (78 FR 50541 through 50544) for detailed information regarding revisions that were made to the CC and CC Exclusion Lists under the ICD-9-CM MS-DRGs. The ICD-10 MS-DRGs Version 35 CC Exclusion List is included as Appendix C in the ICD-10 MS-DRG Definitions Manual, which is available via the internet on the CMS website at: https://www.cms.gov/Medicare/Medicare-Fee-for-Service-Payment/AcuteInpatientPPS/index.html, and includes two lists identified as Part 1 and Part 2. Part 1 is the list of all diagnosis codes that are defined as a CC or MCC when reported as a secondary diagnosis. If the code designated as a CC or MCC is allowed with all principal diagnoses, the phrase ``NoExcl'' (for no exclusions) follows the CC or MCC designation. For example, ICD-10-CM diagnosis code A17.83 (Tuberculous neuritis) has this ``NoExcl'' entry. For all other diagnosis codes on the list, a link is provided to a collection of diagnosis codes which, when used as the principal diagnosis, would cause the CC or MCC diagnosis to be considered as a non-CC. Part 2 is the list of diagnosis codes designated as a MCC only for [[Page 41235]] patients discharged alive; otherwise, they are assigned as a non-CC. In the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20239), for FY 2019, we proposed changes to the ICD-10 MS-DRGs Version 36 CC Exclusion List. Therefore, we developed Table 6G.1.--Proposed Secondary Diagnosis Order Additions to the CC Exclusions List--FY 2019; Table 6G.2.-- Proposed Principal Diagnosis Order Additions to the CC Exclusions List--FY 2019; Table 6H.1.--Proposed Secondary Diagnosis Order Deletions to the CC Exclusions List--FY 2019; and Table 6H.2.--Proposed Principal Diagnosis Order Deletions to the CC Exclusions List--FY 2019. For Table 6G.1, each secondary diagnosis code proposed for addition to the CC Exclusion List is shown with an asterisk and the principal diagnoses proposed to exclude the secondary diagnosis code are provided in the indented column immediately following it. For Table 6G.2, each of the principal diagnosis codes for which there is a CC exclusion is shown with an asterisk and the conditions proposed for addition to the CC Exclusion List that will not count as a CC are provided in an indented column immediately following the affected principal diagnosis. For Table 6H.1, each secondary diagnosis code proposed for deletion from the CC Exclusion List is shown with an asterisk followed by the principal diagnosis codes that currently exclude it. For Table 6H.2, each of the principal diagnosis codes is shown with an asterisk and the proposed deletions to the CC Exclusions List are provided in an indented column immediately following the affected principal diagnosis. Tables 6G.1., 6G.2., 6H.1., and 6H.2. associated with the proposed rule are available via the internet on the CMS website at: https://www.cms.gov/Medicare/Medicare-Fee-for-Service-Payment/AcuteInpatientPPS/index.html. To identify new, revised and deleted diagnosis and procedure codes, for FY 2019, we developed Table 6A.--New Diagnosis Codes, Table 6B.-- New Procedure Codes, Table 6C.--Invalid Diagnosis Codes, Table 6D.-- Invalid Procedure Codes, Table 6E.--Revised Diagnosis Code Titles, and Table 6F.--Revised Procedure Code Titles for the proposed rule and this final rule. These tables are not published in the Addendum to the proposed rule or the final rule but are available via the internet on the CMS website at: https://www.cms.gov/Medicare/Medicare-Fee-for-Service-Payment/AcuteInpatientPPS/index.html as described in section VI. of the Addendum to this final rule. As discussed in section II.F.18. of the preamble of this final rule, the code titles are adopted as part of the ICD-10 (previously ICD-9-CM) Coordination and Maintenance Committee process. Therefore, although we publish the code titles in the IPPS proposed and final rules, they are not subject to comment in the proposed or final rules. In the FY 2019 IPPS/LTCH PPS proposed rule, we invited public comments on the MDC and MS-DRG assignments for the new diagnosis and procedure codes as set forth in Table 6A.--New Diagnosis Codes and Table 6B.--New Procedure Codes. In addition, we invited public comments on the proposed severity level designations for the new diagnosis codes as set forth in Table 6A. and the proposed O.R. status for the new procedure codes as set forth in Table 6B. Comment: One commenter addressed the proposed MS-DRG assignment for ICD-10-CM diagnosis code K35.20 (Acute appendicitis with generalized peritonitis, without abscess) that was included in Table 6A.--New Diagnosis Codes associated with the proposed rule. The commenter included the following codes that describe conditions involving appendicitis with peritonitis, abscess, perforation and gangrene. ------------------------------------------------------------------------ ICD-10-CM code Code description Proposed MS-DRG ------------------------------------------------------------------------ K35.20..................... Acute appendicitis with 371, 372, 373 generalized peritonitis, without abscess. K35.21..................... Acute appendicitis with 338, 339, 340 generalized peritonitis, 371, 372, 373 with abscess. K35.30..................... Acute appendicitis with 371, 372, 373 localized peritonitis, without perforation or gangrene. K35.31..................... Acute appendicitis with 371, 372, 373 localized peritonitis and gangrene, without perforation. K35.32..................... Acute appendicitis with 338, 339, 340 perforation and 371, 372, 373 localized peritonitis, without abscess. K35.33..................... Acute appendicitis with 338, 339, 340 perforation and 371, 372, 373 localized peritonitis, with abscess. K35.890.................... Other acute appendicitis 371, 372, 373 without perforation or gangrene. K35.891.................... Other acute appendicitis 371, 372, 373 without perforation, with gangrene. ------------------------------------------------------------------------ The commenter stated that the proposed MS-DRG assignment for diagnosis code K35.20 is inappropriate and urged CMS to assign additional MS-DRGs and revise Table 6A. Specifically, the commenter expressed concern that MS-DRGs 371, 372, and 373 (Major Gastrointestinal Disorders and Peritoneal Infections with MCC, with CC, and without CC/MCC, respectively) were the only MS-DRGs assigned to diagnosis code K35.20 and requested that MS-DRGs 338, 339, and 340 (Appendectomy with Complicated Principal Diagnosis with MCC, with CC, and without CC/MCC, respectively) also be assigned. The commenter questioned why CMS only assigned MS-DRGs 371, 372, and 373 for diagnosis code K35.20 when diagnosis code K35.32 was assigned to MS- DRGs 338, 339, and 340 in addition to MS-DRGs 371, 372, and 373. The commenter stated that the FY 2019 ICD-10-CM Tabular List of Diseases and Injuries indicates that codes at the new subcategory K35.2 include a ruptured or perforated appendix, which is a complicating diagnosis and requires additional resources. The commenter expressed concern that the proposed MS-DRG assignment for diagnosis code K35.20 does not appropriately reflect the complications of the underlying disease or resources associated with acute appendicitis with generalized peritonitis. The commenter also noted that studies of patients admitted with appendicitis define complicated appendicitis as the presence of either generalized peritonitis due to perforated appendicitis or appendicular abscess. The commenter further noted that an appendix may perforate and cause generalized peritonitis without abscess if the perforation is walled off from the remainder of the peritoneal cavity because of its retroperitoneal location or by loops of small intestine or omentum. Response: We note that the predecessor code for new diagnosis code K35.20 is diagnosis code K35.2 (Acute appendicitis with generalized peritonitis), which is currently assigned [[Page 41236]] to MS-DRGs 338, 339, 340, 371, 372, and 373. Diagnosis code K35.2 was subdivided into diagnosis codes K35.20 and K35.21. In assigning the proposed MS-DRGs for these new diagnosis codes, we considered the predecessor code MS-DRG assignment and the descriptions of the new diagnosis codes. Our clinical advisors determined that diagnosis code K35.21 ``with abscess'' was more appropriate to assign to MS-DRGs 338, 339, and 340 in addition to MS-DRGs 371, 372, and 373 versus diagnosis code K35.20 ``without abscess''. The degree and severity of the peritonitis in a patient with acute appendicitis can vary greatly. However, not all patients with peritonitis develop an abscess. While we agree that peritonitis is a serious condition when it develops in a patient with acute appendicitis, we also believe that, clinically, an abscess presents an even greater risk of complications that requires more resources as discussed in section II.F.15.b. of the preamble of this final rule with regard to the severity level designation. We also consulted with the staff at the Centers for Disease Control's (CDC's) National Center for Health Statistics (NCHS) because NCHS has the lead responsibility for maintaining the ICD-10-CM diagnosis codes. The NCHS' staff acknowledged the clinical concerns of the commenter based on the manner in which diagnosis codes K35.2 and K35.3 were expanded and confirmed that they will consider further review of these newly expanded codes with respect to the clinical concepts. Therefore, we maintain that the proposed MS-DRG assignment for diagnosis code K35.20 as shown in Table 6A is appropriate. Because the diagnosis codes that the commenter submitted in its comments are new, effective October 1, 2018, we do not yet have any claims data. We will continue to monitor these codes as data become available. After consideration of the public comments we received, we are finalizing our proposal to assign diagnosis code K35.20 to MS-DRGs 371, 372, and 373 under the ICD-10 MS-DRGs Version 36, effective October 1, 2018. Comment: One commenter recommended that the following new diagnosis codes that were included in Table 6A.--New Diagnosis Codes--FY 2019, be designated as a CC in the ICD-10-CM classification. ------------------------------------------------------------------------ ICD-10-CM code Code description ------------------------------------------------------------------------ K61.31......................... Horseshoe abscess. K61.39......................... Other ischiorectal abscess. K61.5.......................... Supralevator abscess. K82.A1......................... Gangrene of gallbladder in cholecystitis. O86.00......................... Infection of obstetric surgical wound, unspecified. O86.01......................... Infection of obstetric surgical wound, superficial incisional site. O86.02......................... Infection of obstetric surgical wound, deep incisional site. O86.03......................... Infection of obstetric surgical wound, organ and space site. O86.09......................... Infection of obstetric surgical wound, other surgical site. ------------------------------------------------------------------------ According to the commenter, abscesses, postoperative infections, and gangrene of gallbladder warrant the CC designation because they are acute conditions and require antibiotics or surgical treatment and impact the length of stay. The commenter noted that, currently, diagnosis codes K61.3 (Ischiorectal abscess) and K61.4 (Intrasphincteric abscess) are designated as CCs. The commenter also noted that gangrene of gallbladder classifies to acute cholecystitis, which is a CC, and recommended that the codes listed in the above table all be designated as CCs. Response: We appreciate the commenter's feedback on the proposed severity level designations of the diagnosis codes that were included in Table 6A.--New Diagnosis Codes--FY 2019. The commenter is correct that, currently, diagnosis codes K61.3 and K61.4 are designated as CCs. However, our clinical advisors reviewed diagnosis codes K61.31, K61.39, and K61.5 and continue to support maintaining the proposed non-CC designation because they do not agree from a clinical perspective that these conditions warrant a CC designation or significantly impact resource utilization as a secondary diagnosis. Specifically, our clinical advisors believe that these diagnosis codes described conditions that can range in severity and subsequently, the treatment that is rendered. With regard to the commenter's statement that abscesses, postoperative infections, and gangrene of gallbladder warrant the CC designation because they are acute conditions and require antibiotics or surgical treatment and impact the length of stay, we note that there are various types of abscesses and postoperative infections with varying levels of severity that do not always warrant surgical intervention. With regard to the commenter's statement that gangrene of gallbladder classifies to acute cholecystitis which is a CC, we acknowledge that, currently, diagnosis code K81.0 (Acute cholecystitis) is a CC and has an inclusion term for gangrene of gallbladder. However, the new code description does not include the term ``acute''. Upon review of code K82.A1, our clinical advisors continue to support maintaining the proposed non-CC designation because they do not agree from a clinical perspective that this condition warrants a CC designation or significantly impacts resource utilization as a secondary diagnosis as the primary diagnosis likely is a more significant contributor to resource utilization. With regard to the codes describing infection of obstetrical wound of varying degrees and depths, the predecessor code O86.0 (Infection of obstetric wound) is currently classified as a non-CC and our clinical advisors agreed that, in the absence of data for the new codes, they are appropriately designated as non-CCs. After consideration of the public comments we received, we are finalizing our proposed severity level assignments for the above listed diagnosis codes under the ICD-10 MS-DRGs Version 36, effective October 1, 2018. We also are making available on the CMS website at https://www.cms.gov/Medicare/Medicare-Fee-for-Service-Payment/AcuteInpatientPPS/index.html the following final tables associated with this final rule: Table 6A.--New Diagnosis Codes--FY 2019; Table 6B.--New Procedure Codes--FY 2019; Table 6C.--Invalid Diagnosis Codes--FY 2019; [[Page 41237]] Table 6D.--Invalid Procedure Codes--FY 2019; Table 6E.--Revised Diagnosis Code Titles--FY 2019; Table 6F.--Revised Procedure Code Titles--FY 2019; Table 6G.1.--Secondary Diagnosis Order Additions to the CC Exclusions List--FY 2019; Table 6G.2.--Principal Diagnosis Order Additions to the CC Exclusions List--FY 2019; Table 6H.1.--Secondary Diagnosis Order Deletions to the CC Exclusions List--FY 2019; Table 6H.2.--Principal Diagnosis Order Deletions to the CC Exclusions List--FY 2019; Table 6I.1.--Additions to the MCC List--FY 2019; Table 6I.2.-Deletions to the MCC List--FY 2019; Table 6J.1.--Additions to the CC List--FY 2019; and Table 6J.2.--Deletions to the CC List--FY 2019. We note that, as discussed in section II.F.15.c. of the preamble of this final rule, we proposed, and in this final rule are finalizing, to delete Table 6L. and Table 6M. from the ICD-10 MS-DRG Definitions Manual for FY 2019. 16. Comprehensive Review of CC List for FY 2019 a. Overview of Comprehensive CC/MCC Analysis In the FY 2008 IPPS/LTCH PPS final rule (72 FR 47159), we described our process for establishing three different levels of CC severity into which we would subdivide the diagnosis codes. The categorization of diagnoses as an MCC, a CC, or a non-CC was accomplished using an iterative approach in which each diagnosis was evaluated to determine the extent to which its presence as a secondary diagnosis resulted in increased hospital resource use. We refer readers to the FY 2008 IPPS/ LTCH PPS final rule (72 FR 47159) for a complete discussion of our approach. Since this comprehensive analysis was completed for FY 2008, we have evaluated diagnosis codes individually when receiving requests to change the severity level of specific diagnosis codes. However, given the transition to ICD-10-CM and the significant changes that have occurred to diagnosis codes since this review, we believe it is necessary to conduct a comprehensive analysis once again. We have begun this analysis and will discuss our findings in future rulemaking. We are currently using the same methodology utilized in FY 2008 and described below to conduct this analysis. For each secondary diagnosis, we measured the impact in resource use for the following three subsets of patients: (1) Patients with no other secondary diagnosis or with all other secondary diagnoses that are non-CCs. (2) Patients with at least one other secondary diagnosis that is a CC but none that is an MCC. (3) Patients with at least one other secondary diagnosis that is an MCC. Numerical resource impact values were assigned for each diagnosis as follows: ------------------------------------------------------------------------ Value Meaning ------------------------------------------------------------------------ 0................................ Significantly below expected value for the non-CC subgroup. 1................................ Approximately equal to expected value for the non-CC subgroup. 2................................ Approximately equal to expected value for the CC subgroup. 3................................ Approximately equal to expected value for the MCC subgroup. 4................................ Significantly above the expected value for the MCC subgroup. ------------------------------------------------------------------------ Each diagnosis for which Medicare data were available was evaluated to determine its impact on resource use and to determine the most appropriate CC subclass (non-CC, CC, or MCC) assignment. In order to make this determination, the average cost for each subset of cases was compared to the expected cost for cases in that subset. The following format was used to evaluate each diagnosis: -------------------------------------------------------------------------------------------------------------------------------------------------------- -------------------------------------------------------------------------------------------------------------------------------------------------------- Code Diagnosis Cnt1 C1 Cnt2 C2 Cnt3 C3 -------------------------------------------------------------------------------------------------------------------------------------------------------- Count (Cnt) is the number of patients in each subset and C1, C2, and C3 are a measure of the impact on resource use of patients in each of the subsets. The C1, C2, and C3 values are a measure of the ratio of average costs for patients with these conditions to the expected average cost across all cases. The C1 value reflects a patient with no other secondary diagnosis or with all other secondary diagnoses that are non-CCs. The C2 value reflects a patient with at least one other secondary diagnosis that is a CC but none that is a major CC. The C3 value reflects a patient with at least one other secondary diagnosis that is a major CC. A value close to 1.0 in the C1 field would suggest that the code produces the same expected value as a non-CC diagnosis. That is, average costs for the case are similar to the expected average costs for that subset and the diagnosis is not expected to increase resource usage. A higher value in the C1 (or C2 and C3) field suggests more resource usage is associated with the diagnosis and an increased likelihood that it is more like a CC or major CC than a non-CC. Thus, a value close to 2.0 suggests the condition is more like a CC than a non- CC but not as significant in resource usage as an MCC. A value close to 3.0 suggests the condition is expected to consume resources more similar to an MCC than a CC or non-CC. For example, a C1 value of 1.8 for a secondary diagnosis means that for the subset of patients who have the secondary diagnosis and have either no other secondary diagnosis present, or all the other secondary diagnoses present are non-CCs, the impact on resource use of the secondary diagnoses is greater than the expected value for a non-CC by an amount equal to 80 percent of the difference between the expected value of a CC and a non- CC (that is, the impact on resource use of the secondary diagnosis is closer to a CC than a non-CC). These mathematical constructs are used as guides in conjunction with the judgment of our clinical advisors to classify each secondary diagnosis reviewed as an MCC, CC or non-CC. Our clinical panel reviews the resource use impact reports and suggests modifications to the initial CC subclass assignments when clinically appropriate. b. Requested Changes to Severity Levels (1) Human Immunodeficiency Virus [HIV] Disease As discussed in the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20241), we received a request that we consider changing the severity level of ICD-10-CM diagnosis code B20 (Human immunodeficiency virus [HIV] disease) from an MCC to a CC. We used the approach outlined above to evaluate this request. The table below contains the data that were evaluated for this request. [[Page 41238]] -------------------------------------------------------------------------------------------------------------------------------------------------------- Proposed ICD-10-CM diagnosis code Cnt1 C1 Cnt2 C2 Cnt3 C3 Current CC CC subclass subclass -------------------------------------------------------------------------------------------------------------------------------------------------------- B20 (Human immunodeficiency virus [HIV] disease)........ 2,918 0.9946 8,938 2.1237 11,479 3.0960 MCC CC -------------------------------------------------------------------------------------------------------------------------------------------------------- We stated in the proposed rule that while the data did not strongly suggest that the categorization of HIV as an MCC was inaccurate, our clinical advisors indicated that, for many patients with HIV disease, symptoms are well controlled by medications. Our clinical advisors stated that if these patients have an HIV-related complicating disease, that complicating disease would serve as a CC or an MCC. Therefore, they advised us that ICD-10-CM diagnosis code B20 is more similar to a CC than an MCC. Based on the data results and the advice of our clinical advisors, we proposed to change the severity level of ICD-10- CM diagnosis code B20 from an MCC to a CC. Comment: Commenters opposed the proposal to change the severity level for ICD-10-CM diagnosis code B20 from an MCC to a CC. The commenters stated that the change should not be made without strong supporting empirical data, referencing the language in the proposed rule that indicated that the data did not strongly suggest that the categorization of HIV as an MCC was inaccurate. One commenter indicated that patients with CD4 counts of less than 100, or elevated viral loads, would need more laboratory tests, more imaging, and a higher level of care even if they are in the hospital for a non-HIV related condition. This commenter suggested that if diagnosis code B20 is changed to a CC, CMS develop distinct codes for patients with AIDS based on their level of CD4 and whether viral loads are suppressed. Response: While we stated in the proposed rule that the data did not strongly suggest correlation of a secondary diagnosis code of B20 with a severity level of an MCC was inaccurate, the data also did not definitively support maintaining a severity level of an MCC. While we understand that HIV is a serious disease that causes significant chronic illness and can lead to serious complications, we note that when a patient is admitted for a non-HIV related condition, our clinical advisors do not believe that the secondary diagnosis of HIV would be expected to result in the additional resources associated with an MCC. As explained in the proposed rule, our clinical advisors believe that, for many patients with HIV disease, symptoms are well controlled by medications, and if these patients have an HIV-related complicating disease, that complicating disease would serve as a CC or an MCC. For these reasons, our clinical advisors continue to believe that ICD-10-CM diagnosis code B20 is more accurately characterized as a CC. As discussed in section II.F.18. of the preamble of this final rule, requests for new ICD-10-CM diagnosis codes are discussed at the ICD-10 Coordination and Maintenance Committee meetings. We refer the commenter to the National Center for Health Statistics (NCHS) website at https://www.cdc.gov/nchs/icd/icd10_maintenance.html for further information regarding these meetings and the process for how to request code updates. After consideration of the public comments we received, we are finalizing our proposal to change the severity level of diagnosis code of B20 from an MCC to a CC. (2) Acute Respiratory Distress Syndrome As discussed in the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20241), we also received a request to change the severity level for ICD-10-CM diagnosis code J80 (Acute respiratory distress syndrome) from a CC to a MCC. We used the approach outlined above to evaluate this request. The following table contains the data that were evaluated for this request. -------------------------------------------------------------------------------------------------------------------------------------------------------- Proposed ICD-10-CM diagnosis code Cnt1 C1 Cnt2 C2 Cnt3 C3 Current CC CC subclass subclass -------------------------------------------------------------------------------------------------------------------------------------------------------- J80 (Acute respiratory distress syndrome)............... 1,840 1.7704 6,818 2.5596 18,376 3.3428 CC MCC -------------------------------------------------------------------------------------------------------------------------------------------------------- We stated in the proposed rule that the data suggest that the resources involved in caring for a patient with this condition are 77 percent greater than expected when the patient has either no other secondary diagnosis present or all the other secondary diagnoses present are non-CCs. The resources are 56 percent greater than expected when reported in conjunction with another secondary diagnosis that is a CC, and 34 percent greater than expected when reported in conjunction with another secondary diagnosis code that is an MCC. Our clinical advisors agreed that the resources required to care for a patient with this secondary diagnosis are consistent with those of an MCC. Therefore, we proposed to change the severity level of ICD-10-CM diagnosis code J80 from a CC to an MCC. Comment: Commenters supported the proposal to change the severity level of ICD-10-CM diagnosis code J80 from a CC to an MCC. Response: We appreciate the commenters' support. After consideration of the public comments we received, we are finalizing our proposal to change the severity level of ICD-10-CM diagnosis code J80 from a CC to an MCC. (3) Encephalopathy As discussed in the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20241), we also received a request to change the severity level for ICD-10-CM diagnosis code G93.40 (Encephalopathy, unspecified) from an MCC to a non-CC. The requestor pointed out that the nature of the encephalopathy or its underlying cause should be coded. The requestor also noted that unspecified heart failure is a non-CC. We used the approach outlined earlier to evaluate this request. The following table contains the data that were evaluated for this request. [[Page 41239]] -------------------------------------------------------------------------------------------------------------------------------------------------------- Proposed ICD-10-CM diagnosis code Cnt1 C1 Cnt2 C2 Cnt3 C3 Current CC CC subclass subclass -------------------------------------------------------------------------------------------------------------------------------------------------------- G93.40 (Encephalopathy, unspecified).................... 16,306 1.840 80,222 1.8471 139,066 2.4901 MCC MCC -------------------------------------------------------------------------------------------------------------------------------------------------------- We stated in the proposed rule that the data suggest that the resources involved in caring for a patient with this condition are 84 percent greater than expected when the patient has either no other secondary diagnosis present or all the other secondary diagnoses present are non-CCs. We stated in the proposed rule that the resources are 15 percent lower than expected when reported in conjunction with another secondary diagnosis that is a CC, and 49 percent lower than expected when reported in conjunction with another secondary diagnosis code that is an MCC. The sentence should have read as follows: The resources are 15 percent lower than expected when reported in conjunction with another secondary diagnosis that is a CC, and 51 percent lower than expected when reported in conjunction with another secondary diagnosis code that is an MCC. We noted that the pattern observed in resource use for the condition of unspecified heart failure (ICD-10-CM diagnosis code I50.9) differs from that of unspecified encephalopathy. Our clinical advisors reviewed this request and agreed that, from a clinical standpoint, the resources involved in caring for a patient with this condition are aligned with those of an MCC. Therefore, we did not propose a change to the severity level for ICD- 10-CM diagnosis code G93.40. Comment: Several commenters supported the proposal to maintain the severity level for ICD-10-CM diagnosis code G93.40 as an MCC. One commenter opposed the proposal, stating that unspecified encephalopathy is poorly defined, not all specified encephalopathies are MCCs, and the MCC status creates an incentive for coding personnel to not pursue specificity of encephalopathy which could lead to a lower relative weight. Response: We appreciate the commenters' support. After reviewing the rationale provided by the commenter who opposed our proposal, we concur with the commenter that unspecified encephalopathy is poorly defined, not all encephalopathies are MCCs, and the MCC status creates an incentive for coding personnel to not pursue specificity of encephalopathy. For these reason, our clinical advisors agree that it is appropriate to change the severity level from an MCC to a CC. After consideration of the public comments we received, we are changing the severity level for ICD-10-CM diagnosis code G93.40 from an MCC to a CC. (4) End-Stage Heart Failure and Hepatic Encephalopathy Comment: One commenter stated that ICD-10-CM code I50.84 (End-stage heart failure) should be assigned the severity level of a CC and that hepatic encephalopathy should be assigned the severity level of an MCC. The commenter did not provide the specific ICD-10-CM diagnosis codes that describe hepatic encephalopathy. Response: Because ICD-10-CM code I50.84 and the codes that describe hepatic encephalopathy referred to by the commenter are newly created codes, we do not yet have data with which to evaluate the commenter's request. We will consider these diagnosis codes during our ongoing comprehensive CC/MCC analysis once data become available. After consideration of the public comment received, we are not changing the severity level of ICD-10-CM code I50.84 or the ICD-10-CM codes describing hepatic encephalopathy for FY 2019. 17. Review of Procedure Codes in MS DRGs 981 Through 983 and 987 Through 989 Each year, we review cases assigned to MS-DRGs 981, 982, and 983 (Extensive O.R. Procedure Unrelated to Principal Diagnosis with MCC, with CC, and without CC/MCC, respectively) and MS-DRGs 987, 988, and 989 (Nonextensive O.R. Procedure Unrelated to Principal Diagnosis with MCC, with CC, and without CC/MCC, respectively) to determine whether it would be appropriate to change the procedures assigned among these MS- DRGs. MS-DRGs 981 through 983 and 987 through 989 are reserved for those cases in which none of the O.R. procedures performed are related to the principal diagnosis. These MS-DRGs are intended to capture atypical cases, that is, those cases not occurring with sufficient frequency to represent a distinct, recognizable clinical group. a. Moving Procedure Codes From MS-DRGs 981 Through 983 or MS-DRGs 987 Through 989 Into MDCs We annually conduct a review of procedures producing assignment to MS-DRGs 981 through 983 (Extensive O.R. Procedure Unrelated to Principal Diagnosis with MCC, with CC, and without CC/MCC, respectively) or MS-DRGs 987 through 989 (Nonextensive O.R. Procedure Unrelated to Principal Diagnosis with MCC, with CC, and without CC/MCC, respectively) on the basis of volume, by procedure, to see if it would be appropriate to move procedure codes out of these MS-DRGs into one of the surgical MS-DRGs for the MDC into which the principal diagnosis falls. The data are arrayed in two ways for comparison purposes. We look at a frequency count of each major operative procedure code. We also compare procedures across MDCs by volume of procedure codes within each MDC. We identify those procedures occurring in conjunction with certain principal diagnoses with sufficient frequency to justify adding them to one of the surgical MS-DRGs for the MDC in which the diagnosis falls. Based on the results of our review of the claims data from the September 2017 update of the FY 2017 MedPAR file, in the FY 2019 IPPS/ LTCH PPS proposed rule (83 FR 20242), we did not propose to move any procedures from MS-DRGs 981 through 983 or MS-DRGs 987 through 989 into one of the surgical MS-DRGs for the MDC into which the principal diagnosis is assigned. Comment: One commenter identified two scenarios that involve some cases that are grouping to MS-DRGs 981 through 983 and MS-DRGs 987 through 989. The commenter stated that these grouping issues should be addressed by CMS and provided specific examples with a combination of several codes. Response: We appreciate the commenter bringing these issues to our attention. However, we were unable to fully evaluate these scenarios for consideration in FY 2019. We intend to review and consider these items for FY 2020 as part of our ongoing analysis of the unrelated procedure MS-DRGs. As stated in section II.F.1.b. of the preamble of this final rule, we encourage individuals with comments about MS-DRG classification issues to submit these comments no later than November 1 of each year so that they can be considered for possible inclusion in the annual proposed rule. After consideration of the public comments we received, we are not [[Page 41240]] moving any procedures from MS-DRGs 981 through 983 or MS-DRGs 987 through 989 into one of the surgical MS-DRGs for the MDC into which the principal diagnosis is assigned for FY 2019. b. Reassignment of Procedures Among MS-DRGs 981 Through 983 and 987 Through 989 We also review the list of ICD-10-PCS procedures that, when in combination with their principal diagnosis code, result in assignment to MS-DRGs 981 through 983, or 987 through 989, to ascertain whether any of those procedures should be reassigned from one of those two groups of MS-DRGs to the other group of MS-DRGs based on average costs and the length of stay. We look at the data for trends such as shifts in treatment practice or reporting practice that would make the resulting MS-DRG assignment illogical. If we find these shifts, we would propose to move cases to keep the MS-DRGs clinically similar or to provide payment for the cases in a similar manner. Generally, we move only those procedures for which we have an adequate number of discharges to analyze the data. Based on the results of our review of the September 2017 update of the FY 2017 MedPAR file, we also proposed to maintain the current structure of MS-DRGs 981 through 983 and MS-DRGs 987 through 989. Comment: One commenter recommended that CMS classify the insertion and revision of intracardiac pacemakers as discussed in section II.F.4.a. of the proposed rule (83 FR 20204) as extensive O.R. procedures (MS-DRG 981 through 983). The commenter performed its own analysis where the results demonstrated the average costs of the intracardiac pacemakers were higher than the average costs of cases in MS-DRGs 981 through 983. Response: We are unclear as to the nature of the commenter's request, as the intracardiac pacemaker procedure codes are already designated as extensive O.R. procedures in the GROUPER logic, as discussed in section II.F.4.a. of the preamble of this final rule After consideration of the public comments we received, we are finalizing our proposal to maintain the current structure of MS-DRGs 981 through 983 and MS-DRGs 987 through 989 under the ICD-10 MS-DRGs Version 36, effective October 1, 2018. c. Adding Diagnosis or Procedure Codes to MDCs We received a request recommending that CMS reassign cases for congenital pectus excavatum (congenital depression of the sternum or concave chest) when reported with a procedure describing repositioning of the sternum (the Nuss procedure) from MS-DRGs 981, 982, and 983 (Extensive O.R. Procedure Unrelated to Principal Diagnosis with MCC, with CC, and without CC/MCC, respectively) to MS-DRGs 515, 516, and 517 (Other Musculoskeletal System and Connective Tissue O.R. Procedures with MCC, with CC, and without CC/MCC, respectively). ICD-10-CM diagnosis code Q67.6 (Pectus excavatum) is reported for this congenital condition and is currently assigned to MDC 4 (Diseases and Disorders of the Respiratory System). ICD-10-PCS procedure code 0PS044Z (Reposition sternum with internal fixation device, percutaneous endoscopic approach) may be reported to identify the Nuss procedure and is currently assigned to MDC 8 (Diseases and Disorders of the Musculoskeletal System and Connective Tissue) in MS-DRGs 515, 516, and 517. The requester noted that acquired pectus excavatum (ICD-10-CM diagnosis code M95.4) groups to MS-DRGs 515, 516, and 517 when reported with a ICD-10-PCS procedure code describing repositioning of the sternum and requested that cases involving diagnoses describing congenital pectus excavatum also group to those MS-DRGs when reported with a ICD-10-PCS procedure code describing repositioning of the sternum. Our analysis of this grouping issue confirmed that, when pectus excavatum (ICD-10-CM diagnosis code Q67.6) is reported as a principal diagnosis with a procedure such as the Nuss procedure (ICD-10-PCS procedure code 0PS044Z), these cases group to MS-DRGs 981, 982, and 983. The reason for this grouping is because whenever there is a surgical procedure reported on a claim, which is unrelated to the MDC to which the case was assigned based on the principal diagnosis, it results in an MS-DRG assignment to a surgical class referred to as ``unrelated operating room procedures.'' In the example provided, because the ICD-10-CM diagnosis code Q67.6 describing pectus excavatum is classified to MDC 4 and the ICD-10-PCS procedure code 0PS044Z is classified to MDC 8, the GROUPER logic assigns this case to the ``unrelated operating room procedures'' set of MS-DRGs. During our review of ICD-10-CM diagnosis code Q67.6, we also reviewed additional ICD-10-CM diagnosis codes in the Q65 through Q79 code range to determine if there might be other conditions classified to MDC 4 that describe congenital malformations and deformities of the musculoskeletal system. We identified the following six ICD-10-CM diagnosis codes: ------------------------------------------------------------------------ ICD-10-CM code Code description ------------------------------------------------------------------------ Q67.7.......................... Pectus carinatum. Q76.6.......................... Other congenital malformations of ribs. Q76.7.......................... Congenital malformation of sternum. Q76.8.......................... Other congenital malformations of bony thorax. Q76.9.......................... Congenital malformation of bony thorax, unspecified. Q77.2.......................... Short rib syndrome. ------------------------------------------------------------------------ In the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20243), we proposed to reassign ICD-10-CM diagnosis code Q67.6, as well as the additional six ICD-10-CM diagnosis codes above describing congenital musculoskeletal conditions, from MDC 4 to MDC 8 where other related congenital conditions that correspond to the musculoskeletal system are classified, as discussed further below. We identified other related ICD-10-CM diagnosis codes that are currently assigned to MDC 8 in categories Q67 (Congenital musculoskeletal deformities of head, face, spine and chest), Q76 (Congenital malformations of spine and bony thorax), and Q77 (Osteochondrodysplasia with defects of growth of tubular bones and spine) that are listed in the following table. [[Page 41241]] ------------------------------------------------------------------------ ICD-10-CM code Code description ------------------------------------------------------------------------ Q67.0.......................... Congenital facial asymmetry. Q67.1.......................... Congenital compression facies. Q67.2.......................... Dolichocephaly. Q67.3.......................... Plagiocephaly. Q67.4.......................... Other congenital deformities of skull, face and jaw. Q67.5.......................... Congenital deformity of spine. Q67.8.......................... Other congenital deformities of chest. Q76.1.......................... Klippel-Feil syndrome. Q76.2.......................... Congenital spondylolisthesis. Q76.3.......................... Congenital scoliosis due to congenital bony malformation. Q76.411........................ Congenital kyphosis, occipito-atlanto- axial region. Q76.412........................ Congenital kyphosis, cervical region. Q76.413........................ Congenital kyphosis, cervicothoracic region. Q76.414........................ Congenital kyphosis, thoracic region. Q76.415........................ Congenital kyphosis, thoracolumbar region. Q76.419........................ Congenital kyphosis, unspecified region. Q76.425........................ Congenital lordosis, thoracolumbar region. Q76.426........................ Congenital lordosis, lumbar region. Q76.427........................ Congenital lordosis, lumbosacral region. Q76.428........................ Congenital lordosis, sacral and sacrococcygeal region. Q76.429........................ Congenital lordosis, unspecified region. Q76.49......................... Other congenital malformations of spine, not associated with scoliosis. Q76.5.......................... Cervical rib. Q77.0.......................... Achondrogenesis. Q77.1.......................... Thanatophoric short stature. Q77.3.......................... Chondrodysplasia punctate. Q77.4.......................... Achondroplasia. Q77.5.......................... Diastrophic dysplasia. Q77.6.......................... Chondroectodermal dysplasia. Q77.7.......................... Spondyloepiphyseal dysplasia. Q77.8.......................... Other osteochondrodysplasia with defects of growth of tubular bones and spine. Q77.9.......................... Osteochondrodysplasia with defects of growth of tubular bones and spine, unspecified. ------------------------------------------------------------------------ Next, we analyzed the MS-DRG assignments for the related codes listed above and found that cases with the following conditions are assigned to MS-DRGs 551 and 552 (Medical Back Problems with and without MCC, respectively) under MDC 8. ------------------------------------------------------------------------ ICD-10-CM code Code description ------------------------------------------------------------------------ Q76.2.......................... Congenital spondylolisthesis. Q76.411........................ Congenital kyphosis, occipito-atlanto- axial region. Q76.412........................ Congenital kyphosis, cervical region. Q76.413........................ Congenital kyphosis, cervicothoracic region. Q76.414........................ Congenital kyphosis, thoracic region. Q76.415........................ Congenital kyphosis, thoracolumbar region. Q76.419........................ Congenital kyphosis, unspecified region. Q76.49......................... Other congenital malformations of spine, not associated with scoliosis. ------------------------------------------------------------------------ The remaining conditions shown below are assigned to MS-DRGs 564, 565, and 566 (Other Musculoskeletal System and Connective Tissue Diagnoses with MCC, with CC, and without CC/MCC, respectively) under MDC 8. ------------------------------------------------------------------------ ICD-10-CM code Code description ------------------------------------------------------------------------ Q67.0.......................... Congenital facial asymmetry. Q67.1.......................... Congenital compression facies. Q67.2.......................... Dolichocephaly. Q67.3.......................... Plagiocephaly. Q67.4.......................... Other congenital deformities of skull, face and jaw. Q67.5.......................... Congenital deformity of spine. Q67.8.......................... Other congenital deformities of chest. Q76.1.......................... Klippel-Feil syndrome. Q76.3.......................... Congenital scoliosis due to congenital bony malformation. Q76.425........................ Congenital lordosis, thoracolumbar region. Q76.426........................ Congenital lordosis, lumbar region. Q76.427........................ Congenital lordosis, lumbosacral region. Q76.428........................ Congenital lordosis, sacral and sacrococcygeal region. [[Page 41242]] Q76.429........................ Congenital lordosis, unspecified region. Q76.5.......................... Cervical rib. Q77.0.......................... Achondrogenesis. Q77.1.......................... Thanatophoric short stature. Q77.3.......................... Chondrodysplasia punctate. Q77.4.......................... Achondroplasia. Q77.5.......................... Diastrophic dysplasia. Q77.6.......................... Chondroectodermal dysplasia. Q77.7.......................... Spondyloepiphyseal dysplasia. Q77.8.......................... Other osteochondrodysplasia with defects of growth of tubular bones and spine. Q77.9.......................... Osteochondrodysplasia with defects of growth of tubular bones and spine, unspecified. ------------------------------------------------------------------------ As a result of our review, we proposed to reassign ICD-10-CM diagnosis code Q67.6, as well as the additional six ICD-10-CM diagnosis codes above describing congenital musculoskeletal conditions, from MDC 4 to MDC 8 in MS-DRGs 564, 565, and 566. Our clinical advisors agreed with this proposed reassignment because it is clinically appropriate and consistent with the other related ICD-10-CM diagnosis codes grouped in the Q65 through Q79 range that describe congenital malformations and deformities of the musculoskeletal system that are classified under MDC 8 in MS-DRGs 564, 565, and 566. We stated in the propsed rule that by reassigning ICD-10-CM diagnosis code Q67.6 and the additional six ICD- 10-CM diagnosis codes listed in the table above from MDC 4 to MDC 8, cases reporting these ICD-10-CM diagnosis codes in combination with the respective ICD-10-PCS procedure code will reflect a more appropriate grouping from a clinical perspective because they will now be classified under a surgical musculoskeletal system related MS-DRG and will no longer result in an MS-DRG assignment to the ``unrelated operating room procedures'' surgical class. In summary, we proposed to reassign ICD-10-CM diagnosis codes Q67.6, Q67.7, Q76.6, Q76.7, Q76.8, Q76.9, and Q77.2 from MDC 4 to MDC 8 in MS-DRGs 564, 565, and 566 (Other Musculoskeletal System and Connective Tissue Diagnoses with MCC, with CC, and without CC/MCC, respectively). Comment: Commenters supported the proposal to reassign the seven ICD-10-CM diagnosis codes describing congenital musculoskeletal conditions from MDC 4 to MDC 8 into MS-DRGs 564, 565 and 566. The commenters stated that the proposal was reasonable, given the ICD-10-CM codes and the information provided. Response: We appreciate the commenters' support. After consideration of the public comments we received, we are finalizing the proposal to reassign ICD-10-CM diagnosis codes Q67.6, Q67.7, Q76.6, Q76.7, Q76.8, Q76.9, and Q77.2 from MDC 4 to MDC 8 in MS- DRGs 564, 565, and 566 under the ICD-10 MS-DRGs Version 36, effective October 1, 2018. We also received a request recommending that CMS reassign cases for sternal fracture repair procedures from MS-DRGs 981, 982, and 983 and from MS-DRGs 166, 167 and 168 (Other Respiratory System O.R. Procedures with MCC, with CC and without CC/MCC, respectively) under MDC 4 to MS- DRGs 515, 516, and 517 under MDC 8. The requester noted that clavicle fracture repair procedures with an internal fixation device group to MS-DRGs 515, 516, and 517 when reported with an ICD-10-CM diagnosis code describing a fractured clavicle. However, sternal fracture repair procedures with an internal fixation device group to MS-DRGs 981, 982, and 983 or MS-DRGs 166, 167 and 168 when reported with an ICD-10-CM diagnosis code describing a fracture of the sternum. According to the requestor, because the clavicle and sternum are in the same anatomical region of the body, it would appear that assignment to MS-DRGs 515, 516, and 517 would be more appropriate for sternal fracture repair procedures. The requestor provided the following list of ICD-10-PCS procedure codes in its request for consideration to reassign to MS-DRGs 515, 516 and 517 when reported with an ICD-10-CM diagnosis code for sternal fracture. ------------------------------------------------------------------------ ICD-10-PCS code Code description ------------------------------------------------------------------------ 0PS000Z........................ Reposition sternum with rigid plate internal fixation device, open approach. 0PS004Z........................ Reposition sternum with internal fixation device, open approach. 0PS00ZZ........................ Reposition sternum, open approach. 0PS030Z........................ Reposition sternum with rigid plate internal fixation device, percutaneous approach. 0PS034Z........................ Reposition sternum with internal fixation device, percutaneous approach. ------------------------------------------------------------------------ We noted that the above five ICD-10-PCS procedure codes that may be reported to describe a sternal fracture repair are already assigned to MS-DRGs 515, 516, and 517 under MDC 8. In addition, ICD-10-PCS procedure codes 0PS000Z and 0PS030Z are assigned to MS-DRGs 166, 167 and 168 under MDC 4. As noted in the previous discussion, whenever there is a surgical procedure reported on a claim, which is unrelated to the MDC to which the case was assigned based on the principal diagnosis, it results in an MS-DRG assignment to a surgical class referred to as ``unrelated operating room procedures.'' In the examples provided by the requestor, when the ICD-10-CM diagnosis code describing a sternal fracture is classified under MDC 4 and the ICD-10-PCS procedure code describing a sternal fracture repair procedure is classified under MDC 8, the GROUPER logic assigns these cases to the ``unrelated operating room procedures'' group of MS-DRGs (981, 982, and 983) and when the ICD-10- CM diagnosis code describing a sternal fracture is classified under MDC 4 and the ICD-10-PCS procedure code [[Page 41243]] describing a sternal repair procedure is also classified under MDC 4, the GROUPER logic assigns these cases to MS-DRG 166, 167, or 168. For our review of this grouping issue and the request to have procedures for sternal fracture repairs assigned to MDC 8, we analyzed the ICD-10-CM diagnosis codes describing a sternal fracture currently classified under MDC 4. We identified 10 ICD-10-CM diagnosis codes describing a sternal fracture with an ``initial encounter'' classified under MDC 4 that are listed in the following table. ------------------------------------------------------------------------ ICD-10-CM code Code description ------------------------------------------------------------------------ S22.20XA....................... Unspecified fracture of sternum, initial encounter for closed fracture. S22.20XB....................... Unspecified fracture of sternum, initial encounter for open fracture. S22.21XA....................... Fracture of manubrium, initial encounter for closed fracture. S22.21XB....................... Fracture of manubrium, initial encounter for open fracture. S22.22XA....................... Fracture of body of sternum, initial encounter for closed fracture. S22.22XB....................... Fracture of body of sternum, initial encounter for open fracture. S22.23XA....................... Sternal manubrial dissociation, initial encounter for closed fracture. S22.23XB....................... Sternal manubrial dissociation, initial encounter for open fracture. S22.24XA....................... Fracture of xiphoid process, initial encounter for closed fracture. S22.24XB....................... Fracture of xiphoid process, initial encounter for open fracture. ------------------------------------------------------------------------ Our analysis of this grouping issue confirmed that when 1 of the 10 ICD-10-CM diagnosis codes describing a sternal fracture listed in the table above from MDC 4 is reported as a principal diagnosis with an ICD-10-PCS procedure code for a sternal repair procedure from MDC 8, these cases group to MS-DRG 981, 982, or 983. We also confirmed that when 1 of the 10 ICD-10-CM diagnosis codes describing a sternal fracture listed in the table above from MDC 4 is reported as a principal diagnosis with an ICD-10-PCS procedure code for a sternal repair procedure from MDC 4, these cases group to MS-DRG 166, 167 or 168. Our clinical advisors agreed with the requested reclassification of ICD-10-CM diagnosis codes S22.20XA, S22.20XB, S22.21XA, S22.21XB, S22.22XA, S22.22XB, S22.23XA, S22.23XB, S22.24XA, and S22.24XB describing a sternal fracture with an initial encounter from MDC 4 to MDC 8. They advised that this requested reclassification is clinically appropriate because it is consistent with the other related ICD-10-CM diagnosis codes that describe fractures of the sternum and which are classified under MDC 8. The ICD-10-CM diagnosis codes describing a sternal fracture currently classified under MDC 8 to MS-DRGs 564, 565, and 566 are listed in the following table. ------------------------------------------------------------------------ ICD-10-CM code Code description ------------------------------------------------------------------------ S22.20XD....................... Unspecified fracture of sternum, subsequent encounter for fracture with routine healing. S22.20XG....................... Unspecified fracture of sternum, subsequent encounter for fracture with delayed healing. S22.20XK....................... Unspecified fracture of sternum, subsequent encounter for fracture with nonunion. S22.20XS....................... Unspecified fracture of sternum, sequela. S22.21XD....................... Fracture of manubrium, subsequent encounter for fracture with routine healing. S22.21XG....................... Fracture of manubrium, subsequent encounter for fracture with delayed healing. S22.21XK....................... Fracture of manubrium, subsequent encounter for fracture with nonunion. S22.21XS....................... Fracture of manubrium, sequela. S22.22XD....................... Fracture of body of sternum, subsequent encounter for fracture with routine healing. S22.22XG....................... Fracture of body of sternum, subsequent encounter for fracture with delayed healing. S22.22XK....................... Fracture of body of sternum, subsequent encounter for fracture with nonunion. S22.22XS....................... Fracture of body of sternum, sequela. S22.23XD....................... Sternal manubrial dissociation, subsequent encounter for fracture with routine healing. S22.23XG....................... Sternal manubrial dissociation, subsequent encounter for fracture with delayed healing. S22.23XK....................... Sternal manubrial dissociation, subsequent encounter for fracture with nonunion. S22.23XS....................... Sternal manubrial dissociation, sequela. S22.24XD....................... Fracture of xiphoid process, subsequent encounter for fracture with routine healing. S22.24XG....................... Fracture of xiphoid process, subsequent encounter for fracture with delayed healing. S22.24XK....................... Fracture of xiphoid process, subsequent encounter for fracture with nonunion. S22.24XS....................... Fracture of xiphoid process, sequela. ------------------------------------------------------------------------ We stated in the proposed rule that by reclassifying the 10 ICD-10- CM diagnosis codes listed in the table earlier in this section describing sternal fracture codes with an ``initial encounter'' from MDC 4 to MDC 8, the cases reporting these ICD-10-CM diagnosis codes in combination with the respective ICD-10-PCS procedure codes will reflect a more appropriate grouping from a clinical perspective and will no longer result in an MS-DRG assignment to the ``unrelated operating room procedures'' surgical class when reported with a surgical procedure classified under MDC 8. Therefore, in the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20245), we proposed to reassign ICD-10-CM diagnosis codes S22.20XA, S22.20XB, S22.21XA, S22.21XB, S22.22XA, S22.22XB, S22.23XA, S22.23XB, S22.24XA, and S22.24XB from under MDC 4 to MDC 8 to MS-DRGs 564, 565, and 566. We invited public comments on our proposals. Comment: Commenters supported the proposal to reassign the 10 ICD- 10-CM diagnosis codes describing sternal fractures with an initial encounter from MDC 4 to MDC 8 into MS-DRGs 564, 565 and 566. The commenters stated that the proposal was reasonable, given [[Page 41244]] the ICD-10-CM codes and the information provided. Response: We appreciate the commenters' support. After consideration of the public comments we received, we are finalizing the proposal to reassign ICD-10-CM diagnosis codes S22.20XA, S22.20XB, S22.21XA, S22.21XB, S22.22XA, S22.22XB, S22.23XA, S22.23XB, S22.24XA, and S22.24XB from MDC 4 to MDC 8 to MS-DRGs 564, 565, and 566 under the ICD-10 MS-DRGs Version 36, effective October 1, 2018. In addition, we received a request recommending that CMS reassign cases for rib fracture repair procedures from MS-DRGs 981, 982, and 983, and from MS-DRGs 166, 167 and 168 (Other Respiratory System O.R. Procedures with MCC, with CC, and without CC/MCC, respectively) under MDC 4 to MS-DRGs 515, 516, and 517 under MDC 8. The requestor noted that clavicle fracture repair procedures with an internal fixation device group to MS-DRGs 515, 516, and 517 when reported with an ICD-10- CM diagnosis code describing a fractured clavicle. However, rib fracture repair procedures with an internal fixation device group to MS-DRGs 981, 982, and 983 or to MS-DRGs 166, 167 and 168 when reported with an ICD-10-CM diagnosis code describing a rib fracture. According to the requestor, because the clavicle and ribs are in the same anatomical region of the body, it would appear that assignment to MS- DRGs 515, 516, and 517 would be more appropriate for rib fracture repair procedures. The requestor provided the following list of 10 ICD-10-PCS procedure codes in its request for consideration for reassignment to MS-DRGs 515, 516 and 517 when reported with an ICD-10-CM diagnosis code for rib fracture. ------------------------------------------------------------------------ ICD-10-PCS code Code description ------------------------------------------------------------------------ 0PH104Z................... Insertion of internal fixation device into 1 to 2 ribs, open approach. 0PH134Z................... Insertion of internal fixation device into 1 to 2 ribs, percutaneous approach. 0PH144Z................... Insertion of internal fixation device into 1 to 2 ribs, percutaneous endoscopic approach. 0PH204Z................... Insertion of internal fixation device into 3 or more ribs, open approach. 0PH234Z................... Insertion of internal fixation device into 3 or more ribs, percutaneous approach. 0PH244Z................... Insertion of internal fixation device into 3 or more ribs, percutaneous endoscopic approach. 0PS104Z................... Reposition 1 to 2 ribs with internal fixation device, open approach. 0PS134Z................... Reposition 1 to 2 ribs with internal fixation device, percutaneous approach. 0PS204Z................... Reposition 3 or more ribs with internal fixation, device, open approach. 0PS234Z................... Reposition 3 or more ribs with internal fixation device, percutaneous approach. ------------------------------------------------------------------------ We note that the above 10 ICD-10-PCS procedure codes that may be reported to describe a rib fracture repair are already assigned to MS- DRGs 515, 516, and 517 under MDC 8. In addition, 6 of the 10 ICD-10-PCS procedure codes listed above (0PH104Z, 0PH134Z, 0PH144Z, 0PH204Z, 0PH234Z and 0PH244Z) are also assigned to MS-DRGs 166, 167, and 168 under MDC 4. As noted in the previous discussions above, whenever there is a surgical procedure reported on a claim, which is unrelated to the MDC to which the case was assigned based on the principal diagnosis, it results in an MS-DRG assignment to a surgical class referred to as ``unrelated operating room procedures.'' In the examples provided by the requestor, when the ICD-10-CM diagnosis code describing a rib fracture is classified under MDC 4 and the ICD-10-PCS procedure code describing a rib fracture repair procedure is classified under MDC 8, the GROUPER logic assigns these cases to the ``unrelated operating room procedures'' group of MS-DRGs (981, 982, and 983) and when the ICD-10- CM diagnosis code describing a rib fracture is classified under MDC 4 and the ICD-10-PCS procedure code describing a rib repair procedure is also classified under MDC 4, the GROUPER logic assigns these cases to MS-DRG 166, 167, or 168. For our review of this grouping issue and the request to have procedures for rib fracture repairs assigned to MDC 8, we analyzed the ICD-10-CM diagnosis codes describing a rib fracture and found that, while some rib fracture ICD-10-CM diagnosis codes are classified under MDC 8 (which would result in those cases grouping appropriately to MS- DRGs 515, 516, and 517), there are other ICD-10-CM diagnosis codes that are currently classified under MDC 4. We identified the following ICD- 10-CM diagnosis codes describing a rib fracture with an initial encounter classified under MDC 4, as listed in the following table. ------------------------------------------------------------------------ ICD-10-CM code Code description ------------------------------------------------------------------------ S2231XA................... Fracture of one rib, right side, initial encounter for closed fracture. S2231XB................... Fracture of one rib, right side, initial encounter for open fracture. S2232XA................... Fracture of one rib, left side, initial encounter for closed fracture. S2232XB................... Fracture of one rib, left side, initial encounter for open fracture. S2239XA................... Fracture of one rib, unspecified side, initial encounter for closed fracture. S2239XB................... Fracture of one rib, unspecified side, initial encounter for open fracture.

During our review of those four repositioning of the rib procedure codes, we also identified the following four ICD-10-PCS procedure codes classified to MDC 8 that describe repositioning of the ribs. ------------------------------------------------------------------------ ICD-10-PCS code Code description ------------------------------------------------------------------------ 0PS10ZZ................... Reposition 1 to 2 ribs, open approach. 0PS144Z................... Reposition 1 to 2 ribs with internal fixation device, percutaneous endoscopic approach. 0PS20ZZ................... Reposition 3 or more ribs, open approach. 0PS244Z................... Reposition 3 or more ribs with internal fixation device, percutaneous endoscopic approach. ------------------------------------------------------------------------ We confirmed that when one of the above four procedure codes is reported with a principal diagnosis code for a rib fracture listed in the table above from MDC 4, these cases also group to MS-DRG 981, 982, or 983. Lastly, we confirmed that when one of the six ICD-10-PCS procedure codes describing a rib fracture repair listed in the previous table above from MDC 4 is reported with a principal diagnosis code for a rib fracture with an initial encounter from MDC 4, these cases group to MS- DRG 166, 167, or 168. In response to the request to reassign the procedure codes that describe a rib fracture repair procedure from MS-DRGs 981, 982, and 983 and from MS-DRGs 166, 167, and 168 under MDC 4 to MS-DRGs 515, 516, and 517 under MDC 8, as discussed above, the 10 ICD-10-PCS procedure codes submitted by the requestor that may be reported to describe a rib fracture repair are already assigned to MS-DRGs 515, 516, and 517 under MDC 8 and 6 of those 10 procedure codes (0PH104Z, 0PH134Z, 0PH144Z, 0PH204Z, 0PH234Z, and 0PH244Z) are also assigned to MS-DRGs 166, 167, and 168 under MDC 4. We analyzed claims data from the September 2017 update of the FY 2017 MedPAR file for cases reporting a principal diagnosis of a rib fracture (initial encounter) from the list of diagnosis codes shown in the table above with one of the six ICD-10-PCS procedure codes describing the insertion of an internal fixation device into the rib (0PH104Z, 0PH134Z, 0PH144Z, 0PH204Z, 0PH234Z, and 0PH244Z) in MS-DRGs 166, 167, and 168 under MDC 4. Our findings are shown in the table below. MS-DRGs for Other Respiratory System O.R. Procedures ---------------------------------------------------------------------------------------------------------------- Number of Average length MS-DRG cases of stay Average costs ---------------------------------------------------------------------------------------------------------------- MS-DRG 166-All cases............................................ 22,938 10.2 $24,299 MS-DRG 166-Cases with principal diagnosis of rib fracture(s) and 40 11.4 43,094 insertion of internal fixation device for the rib(s)...........

MS-DRG 168-All cases............................................ 3,242 3.1 9,708 MS-DRG 168-Cases with principal diagnosis of rib fracture(s) and 4 2 21,501 insertion of internal fixation device for the rib(s)........... ---------------------------------------------------------------------------------------------------------------- As shown in this table, there were a total of 22,938 cases in MS- DRG 166, with an average length of stay of 10.2 days and average costs of $24,299. In MS-DRG 166, we found 40 cases reporting a principal diagnosis of a rib fracture(s) with insertion of an internal fixation device for the rib(s), with an average length of stay of 11.4 days and average costs of $43,094. There were a total of 10,815 cases in MS-DRG 167, with an average length of stay of 5.7 days and average costs of $13,252. In MS-DRG 167, we found 10 cases reporting a principal diagnosis of a rib fracture(s) with insertion of an internal fixation device for the rib(s), with an average length of stay of 6.7 days and average costs of $30,617. There were a total of 3,242 cases in MS-DRG 168, with an average length of stay of 3.1 days and average costs of $9,708. In MS-DRG 168, we found 4 cases reporting a principal diagnosis of a rib fracture(s) with insertion of an internal fixation device for the rib(s), with an average length of stay of 2 days and average costs of $21,501. Overall, for MS-DRGs 166, 167, and 168, there were a total of 54 cases reporting a principal diagnosis of a rib fracture(s) with insertion of an internal fixation device for the rib(s), demonstrating that while rib fractures may require treatment, they are not typically corrected surgically. Our clinical advisors agreed with the current assignment of procedure codes to MS-DRGs 166, 167, and 168 that may be reported to describe repair of a rib fracture under MDC 4, as well as the current assignment of procedure codes to MS-DRGs 515, 516, and 517 that may be reported to describe repair of a rib fracture under MDC 8. Our clinical advisors noted that initial, acute rib fractures can cause numerous respiratory related issues requiring various treatments and problems with the healing of a rib fracture are considered musculoskeletal issues. We also noted that the procedure codes submitted by the requestor may be reported for other indications and they are not restricted to reporting for repair of a rib fracture. Therefore, assignment of these codes to the MDC 4 MS-DRGs and the MDC 8 MS-DRGs is clinically appropriate. To address the cases reporting procedure codes describing the [[Page 41246]] repositioning of a rib(s) that are grouping to MS-DRGs 981, 982, and 983 when reported with a principal diagnosis of a rib fracture (initial encounter), in the FY 2019 IPPS/LTCH PPS proposed rule, we proposed to add the following eight ICD-10-PCS procedure codes currently assigned to MDC 8 into MDC 4, in MS-DRGs 166, 167 and 168. ------------------------------------------------------------------------ ICD-10-PCS code Code description ------------------------------------------------------------------------ 0PS104Z................... Reposition 1 to 2 ribs with internal fixation device, open approach. 0PS10ZZ................... Reposition 1 to 2 ribs, open approach. 0PS134Z................... Reposition 1 to 2 ribs with internal fixation device, percutaneous approach. 0PS144Z................... Reposition 1 to 2 ribs with internal fixation device, percutaneous endoscopic approach. 0PS204Z................... Reposition 3 or more ribs with internal fixation device, open approach. 0PS20ZZ................... Reposition 3 or more ribs, open approach. 0PS234Z................... Reposition 3 or more ribs with internal fixation device, percutaneous approach. 0PS244Z................... Reposition 3 or more ribs with internal fixation device, percutaneous endoscopic approach. ------------------------------------------------------------------------ Our clinical advisors agreed with this proposed addition to the classification structure because it is clinically appropriate and consistent with the other related ICD-10-PCS procedure codes that may be reported to describe rib fracture repair procedures with the insertion of an internal fixation device and are classified under MDC 4. We stated in the proposed rule that by adding the eight ICD-10-PCS procedure codes describing repositioning of the rib(s) that may be reported to describe a rib fracture repair procedure under the classification structure for MDC 4, these cases will no longer result in an MS-DRG assignment to the ``unrelated operating room procedures'' surgical class when reported with a diagnosis code under MDC 4. Comment: Commenters supported the proposal to add the eight ICD-10- PCS procedure codes describing repositioning of the ribs to MDC 4 in MS-DRGs 166, 167 and 168. The commenters stated that the proposal was reasonable, given the data, the ICD-10-PCS codes and the information provided. Response: We appreciate the commenters' support. After consideration of the public comments we received, we are finalizing the proposal to add ICD-10-PCS procedure codes 0PS104Z, 0PS10ZZ, 0PS134Z, 0PS144Z, 0PS204Z, 0PS20ZZ, 0PS234Z and 0PS244Z currently assigned to MDC 8 into MDC 4 in MS-DRGs 166, 167 and 168 under the ICD-10 MS-DRGs Version 36, effective October 1, 2018. 18. Changes to the ICD-10-CM and ICD-10-PCS Coding Systems In September 1985, the ICD-9-CM Coordination and Maintenance Committee was formed. This is a Federal interdepartmental committee, co-chaired by the National Center for Health Statistics (NCHS), the Centers for Disease Control and Prevention (CDC), and CMS, charged with maintaining and updating the ICD-9-CM system. The final update to ICD- 9-CM codes was made on October 1, 2013. Thereafter, the name of the Committee was changed to the ICD-10 Coordination and Maintenance Committee, effective with the March 19-20, 2014 meeting. The ICD-10 Coordination and Maintenance Committee addresses updates to the ICD-10- CM and ICD-10-PCS coding systems. The Committee is jointly responsible for approving coding changes, and developing errata, addenda, and other modifications to the coding systems to reflect newly developed procedures and technologies and newly identified diseases. The Committee is also responsible for promoting the use of Federal and non- Federal educational programs and other communication techniques with a view toward standardizing coding applications and upgrading the quality of the classification system. The official list of ICD-9-CM diagnosis and procedure codes by fiscal year can be found on the CMS website at: http://cms.hhs.gov/Medicare/Coding/ICD9ProviderDiagnosticCodes/codes.html. The official list of ICD-10-CM and ICD-10-PCS codes can be found on the CMS website at: http://www.cms.gov/Medicare/Coding/ICD10/index.html. The NCHS has lead responsibility for the ICD-10-CM and ICD-9-CM diagnosis codes included in the Tabular List and Alphabetic Index for Diseases, while CMS has lead responsibility for the ICD-10-PCS and ICD- 9-CM procedure codes included in the Tabular List and Alphabetic Index for Procedures. The Committee encourages participation in the previously mentioned process by health-related organizations. In this regard, the Committee holds public meetings for discussion of educational issues and proposed coding changes. These meetings provide an opportunity for representatives of recognized organizations in the coding field, such as the American Health Information Management Association (AHIMA), the American Hospital Association (AHA), and various physician specialty groups, as well as individual physicians, health information management professionals, and other members of the public, to contribute ideas on coding matters. After considering the opinions expressed at the public meetings and in writing, the Committee formulates recommendations, which then must be approved by the agencies. The Committee presented proposals for coding changes for implementation in FY 2019 at a public meeting held on September 12-13, 2017, and finalized the coding changes after consideration of comments received at the meetings and in writing by November 13, 2017. The Committee held its 2018 meeting on March 6-7, 2018. The deadline for submitting comments on these code proposals was scheduled for April 6, 2018. It was announced at this meeting that any new ICD- 10-CM/PCS codes for which there was consensus of public support and for which complete tabular and indexing changes would be made by May 2018 would be included in the October 1, 2018 update to ICD-10-CM/ICD-10- PCS. As discussed in earlier sections of the preamble of this final rule, there are new, revised, and deleted ICD-10-CM diagnosis codes and ICD-10-PCS procedure codes that are captured in Table 6A.--New Diagnosis Codes, Table 6B.--New Procedure Codes, Table 6C.--Invalid Diagnosis Codes, Table 6D.--Invalid Procedure Codes, Table 6E.--Revised Diagnosis Code Titles, and Table 6F.--Revised Procedure Code Titles for this final rule, which are available via the internet on the CMS website at: http://www.cms.gov/Medicare/Medicare-Fee-for-Service-Payment/AcuteInpatientPPS/index.html. The code titles are adopted as part of the [[Page 41247]] ICD-10 (previously ICD-9-CM) Coordination and Maintenance Committee process. Therefore, although we make the code titles available for the IPPS proposed rule, they are not subject to comment in the proposed rule. Because of the length of these tables, they were not published in the Addendum to the proposed rule. Rather, they are available via the internet as discussed in section VI. of the Addendum to the proposed rule. Live Webcast recordings of the discussions of procedure codes at the Committee's September 12-13, 2017 meeting and March 6-7, 2018 meeting can be obtained from the CMS website at: http://cms.hhs.gov/Medicare/Coding/ICD9ProviderDiagnosticCodes/index.html?redirect=/icd9ProviderDiagnosticCodes/03_meetings.asp. The minutes of the discussions of diagnosis codes at the September 12-13, 2017 meeting and March 6-7, 2018 meeting can be found at: http://www.cdc.gov/nchs/icd/icd10cm_maintenance.html. These websites also provide detailed information about the Committee, including information on requesting a new code, attending a Committee meeting, and timeline requirements and meeting dates. We encourage commenters to address suggestions on coding issues involving diagnosis codes to: Donna Pickett, Co-Chairperson, ICD-10 Coordination and Maintenance Committee, NCHS, Room 2402, 3311 Toledo Road, Hyattsville, MD 20782. Comments may be sent by Email to: [email protected]. Questions and comments concerning the procedure codes should be submitted via Email to: [email protected]. In the September 7, 2001 final rule implementing the IPPS new technology add-on payments (66 FR 46906), we indicated we would attempt to include proposals for procedure codes that would describe new technology discussed and approved at the Spring meeting as part of the code revisions effective the following October. Section 503(a) of Public Law 108-173 included a requirement for updating diagnosis and procedure codes twice a year instead of a single update on October 1 of each year. This requirement was included as part of the amendments to the Act relating to recognition of new technology under the IPPS. Section 503(a) amended section 1886(d)(5)(K) of the Act by adding a clause (vii) which states that the Secretary shall provide for the addition of new diagnosis and procedure codes on April 1 of each year, but the addition of such codes shall not require the Secretary to adjust the payment (or diagnosis-related group classification) until the fiscal year that begins after such date. This requirement improves the recognition of new technologies under the IPPS by providing information on these new technologies at an earlier date. Data will be available 6 months earlier than would be possible with updates occurring only once a year on October 1. While section 1886(d)(5)(K)(vii) of the Act states that the addition of new diagnosis and procedure codes on April 1 of each year shall not require the Secretary to adjust the payment, or DRG classification, under section 1886(d) of the Act until the fiscal year that begins after such date, we have to update the DRG software and other systems in order to recognize and accept the new codes. We also publicize the code changes and the need for a mid-year systems update by providers to identify the new codes. Hospitals also have to obtain the new code books and encoder updates, and make other system changes in order to identify and report the new codes. The ICD-10 (previously the ICD-9-CM) Coordination and Maintenance Committee holds its meetings in the spring and fall in order to update the codes and the applicable payment and reporting systems by October 1 of each year. Items are placed on the agenda for the Committee meeting if the request is received at least 2 months prior to the meeting. This requirement allows time for staff to review and research the coding issues and prepare material for discussion at the meeting. It also allows time for the topic to be publicized in meeting announcements in the Federal Register as well as on the CMS website. Final decisions on code title revisions are currently made by March 1 so that these titles can be included in the IPPS proposed rule. A complete addendum describing details of all diagnosis and procedure coding changes, both tabular and index, is published on the CMS and NCHS websites in June of each year. Publishers of coding books and software use this information to modify their products that are used by health care providers. This 5-month time period has proved to be necessary for hospitals and other providers to update their systems. A discussion of this timeline and the need for changes are included in the December 4-5, 2005 ICD-9-CM Coordination and Maintenance Committee Meeting minutes. The public agreed that there was a need to hold the fall meetings earlier, in September or October, in order to meet the new implementation dates. The public provided comment that additional time would be needed to update hospital systems and obtain new code books and coding software. There was considerable concern expressed about the impact this April update would have on providers. In the FY 2005 IPPS final rule, we implemented section 1886(d)(5)(K)(vii) of the Act, as added by section 503(a) of Public Law 108-173, by developing a mechanism for approving, in time for the April update, diagnosis and procedure code revisions needed to describe new technologies and medical services for purposes of the new technology add-on payment process. We also established the following process for making these determinations. Topics considered during the Fall ICD-10 (previously ICD-9-CM) Coordination and Maintenance Committee meeting are considered for an April 1 update if a strong and convincing case is made by the requester at the Committee's public meeting. The request must identify the reason why a new code is needed in April for purposes of the new technology process. The participants at the meeting and those reviewing the Committee meeting summary report are provided the opportunity to comment on this expedited request. All other topics are considered for the October 1 update. Participants at the Committee meeting are encouraged to comment on all such requests. There were not any requests approved for an expedited April 1, 2018 implementation of a code at the September 12-13, 2017 Committee meeting. Therefore, there were not any new codes for implementation on April 1, 2018. ICD-9-CM addendum and code title information is published on the CMS website at: http://www.cms.hhs.gov/Medicare/Coding/ICD9ProviderDiagnosticCodes/index.html?redirect=/icd9ProviderDiagnosticCodes/01overview.asp#TopofPage. ICD-10-CM and ICD-10-PCS addendum and code title information is published on the CMS website at: http://www.cms.gov/Medicare/Coding/ICD10/index.html. CMS also sends copies of all ICD-10-CM and ICD-10-PCS coding changes to its Medicare contractors for use in updating their systems and providing education to providers. Information on ICD-10-CM diagnosis codes, along with the Official ICD-10-CM Coding Guidelines, can also be found on the CDC website at: http://www.cdc.gov/nchs/icd/icd10.htm. Additionally, information on new, revised, and deleted ICD-10-CM/ICD-10-PCS codes is provided to the AHA for publication in the Coding Clinic for ICD-10. AHA also distributes coding update information to publishers and software vendors. [[Page 41248]] The following chart shows the number of ICD-10-CM and ICD-10-PCS codes and code changes since FY 2016 when ICD-10 was implemented. Total Number of Codes and Changes in Total Number of Codes per Fiscal Year ICD-10-CM and ICD-10-PCS Codes ------------------------------------------------------------------------ Fiscal year Number Change ------------------------------------------------------------------------ FY 2016: ICD-10-CM............................. 69,823 .............. ICD-10-PCS............................ 71,974 ..............

ICD-10-CM............................. 71,932 +228 ICD-10-PCS............................ 78,881 +176 ------------------------------------------------------------------------ As mentioned previously, the public is provided the opportunity to comment on any requests for new diagnosis or procedure codes discussed at the ICD-10 Coordination and Maintenance Committee meeting. At the September 12-13, 2017 and March 6-7, 2018 Committee meetings, we discussed any requests we had received for new ICD-10-CM diagnosis codes and ICD-10-PCS procedure codes that were to be implemented on October 1, 2018. We invited public comments on any code requests discussed at the September 12-13, 2017 and March 6-7, 2018 Committee meetings for implementation as part of the October 1, 2018 update. The deadline for commenting on code proposals discussed at the September 12-13, 2017 Committee meeting was November 13, 2017. The deadline for commenting on code proposals discussed at the March 6-7, 2018 Committee meeting was April 6, 2018. 19. Replaced Devices Offered Without Cost or With a Credit a. Background In the FY 2008 IPPS final rule with comment period (72 FR 47246 through 47251), we discussed the topic of Medicare payment for devices that are replaced without cost or where credit for a replaced device is furnished to the hospital. We implemented a policy to reduce a hospital's IPPS payment for certain MS-DRGs where the implantation of a device that subsequently failed or was recalled determined the base MS- DRG assignment. At that time, we specified that we will reduce a hospital's IPPS payment for those MS-DRGs where the hospital received a credit for a replaced device equal to 50 percent or more of the cost of the device. In the FY 2012 IPPS/LTCH PPS final rule (76 FR 51556 through 51557), we clarified this policy to state that the policy applies if the hospital received a credit equal to 50 percent or more of the cost of the replacement device and issued instructions to hospitals accordingly. b. Changes for FY 2019 In the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20250 through 20251), for FY 2019, we did not propose to add any MS-DRGs to the policy for replaced devices offered without cost or with a credit. We proposed to continue to include the existing MS-DRGs currently subject to the policy as displayed in the table below. ------------------------------------------------------------------------ MDC MS-DRG MS-DRG title ------------------------------------------------------------------------ Pre-MDC........................ 001 Heart Transplant or Implant of Heart Assist System with MCC.

Therefore, we are finalizing the list of MS-DRGs in the table included in the proposed rule and above that will be subject to the replaced devices offered without cost or with a credit policy, effective October 1, 2018. 20. Other Policy Changes: Other Operating Room (O.R.) and Non-O.R. Issues In the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20251 through 20257), we addressed requests that we received regarding changing the designation of specific ICD-10-PCS procedure codes from non-O.R. to O.R. procedures, or changing the designation from O.R. procedure to non-O.R. procedure. In cases where we proposed to change the designation of procedure codes from non-O.R. to O.R. procedures, we also proposed one or more MS-DRGs with which these procedures are clinically aligned and to which the procedure code would be assigned. We generally examine the MS-DRG assignment for similar procedures, such as the other approaches for that procedure, to determine the most appropriate MS-DRG assignment for procedures newly designated as O.R. procedures. We invited public comments on these proposed MS-DRG assignments. We also noted that many MS-DRGs require the presence of any O.R. procedure. As a result, cases with a principal diagnosis associated with a particular MS-DRG would, by default, be grouped to that MS-DRG. Therefore, we do not list these MS-DRGs in our discussion below. Instead, we only discussed MS-DRGs that require explicitly adding the relevant procedures codes to the GROUPER logic in order for those procedure codes to affect the MS-DRG assignment as intended. In addition, cases that contain O.R. procedures will map to MS-DRGs 981, 982, or 983 (Extensive O.R. Procedure Unrelated to Principal Diagnosis with MCC, with CC, and without CC/MCC, respectively) or MS-DRGs 987, 988, or 989 (Non-Extensive O.R. Procedure Unrelated to Principal Diagnosis with MCC, with CC, and without CC/MCC, respectively) when they do not contain a principal diagnosis that corresponds to one of the MDCs to which that procedure is assigned. These procedures need not be assigned to MS-DRGs 981 through 989 in order for this to occur. Therefore, if requestors included some or all of MS-DRGs 981 through 989 in their request or included MS-DRGs that require the presence of any O.R. procedure, we did not specifically address that aspect in summarizing their request or our response to the request in the section below. (a) Percutaneous and Percutaneous Endoscopic Excision of Brain and Cerebral Ventricle One requestor identified 22 ICD-10-PCS procedure codes that describe procedures involving transcranial brain and cerebral ventricle excision that the requestor stated would generally require the resources of an operating room. The 22 procedure codes are listed in the following table. ------------------------------------------------------------------------ ICD-10-PCS procedure code Code description ------------------------------------------------------------------------ 00B03ZX................... Excision of brain, percutaneous approach, diagnostic. [[Page 41250]] 00B13ZX................... Excision of cerebral meninges, percutaneous approach, diagnostic. 00B23ZX...................

Excision of medulla oblongata, percutaneous endoscopic approach, diagnostic. ------------------------------------------------------------------------ The requestor stated that, although percutaneous burr hole biopsies are performed through smaller openings in the skull than open burr hole biopsies, these procedures require drilling or cutting through the skull using sterile technique with anesthesia for pain control. The requestor also noted that similar procedures involving percutaneous drainage of the subdural space are currently classified as O.R. procedures in Version 35 of the ICD-10 MS-DRGs. However, these 22 ICD- 10-PCS procedure codes are not recognized as O.R. procedures for purposes of MS-DRG assignment. The requestor recommended that the 22 ICD-10-PCS codes be designated as O.R. procedures and assigned to MS- DRGs 25, 26, and 27 (Craniotomy and Endovascular Intracranial Procedures with MCC, with CC, and without CC/MCC, respectively). In the proposed rule, we stated that we agreed with the requestor that these procedures typically require the resources of an operating room. Therefore, we proposed to add these 22 ICD-10-PCS procedure codes to the FY 2019 ICD-10 MS-DRGs Version 36 Definitions Manual in Appendix E--Operating Room Procedures and Procedure Code/MS-DRG Index as O.R. procedures assigned to MS-DRGs 25, 26, and 27 in MDC 1 (Diseases and Disorders of the Nervous System). Comment: One commenter supported the proposal to change the designation of the 22 procedure codes listed in the table above to O.R. procedures. Response: We appreciate the commenter's support. After consideration of the public comment we received, we are finalizing our proposal to change the designation of the 22 ICD-10-PCS procedure codes shown in the table above from non-O.R. procedures to O.R. procedures, effective October 1, 2018. b. Open Extirpation of Subcutaneous Tissue and Fascia One requestor identified 22 ICD-10-PCS procedure codes that describe procedures involving open extirpation of subcutaneous tissue and fascia that the requestor stated would generally require the resources of an operating room. The 22 procedure codes are listed in the following table. ------------------------------------------------------------------------ ICD-10-PCS procedure code Code description ------------------------------------------------------------------------ 0JC00ZZ................... Extirpation of matter from scalp subcutaneous tissue and fascia, open approach. 0JC10ZZ................... Extirpation of matter from face subcutaneous tissue and fascia, open approach. 0JC40ZZ................... Extirpation of matter from right neck subcutaneous tissue and fascia, open approach. 0JC50ZZ................... Extirpation of matter from left neck subcutaneous tissue and fascia, open approach. 0JC60ZZ................... Extirpation of matter from chest subcutaneous tissue and fascia, open approach. 0JC70ZZ................... Extirpation of matter from back subcutaneous tissue and fascia, open approach. 0JC80ZZ................... Extirpation of matter from abdomen subcutaneous tissue and fascia, open approach. 0JC90ZZ................... Extirpation of matter from buttock subcutaneous tissue and fascia, open approach. 0JCB0ZZ................... Extirpation of matter from perineum subcutaneous tissue and fascia, open approach. 0JCC0ZZ................... Extirpation of matter from pelvic region subcutaneous tissue and fascia, open approach. 0JCD0ZZ................... Extirpation of matter from right upper arm subcutaneous tissue and fascia, open approach. 0JCF0ZZ................... Extirpation of matter from left upper arm subcutaneous tissue and fascia, open approach. 0JCG0ZZ................... Extirpation of matter from right lower arm subcutaneous tissue and fascia, open approach. 0JCH0ZZ................... Extirpation of matter from left lower arm subcutaneous tissue and fascia, open approach. 0JCJ0ZZ................... Extirpation of matter from right hand subcutaneous tissue and fascia, open approach. 0JCK0ZZ................... Extirpation of matter from left hand subcutaneous tissue and fascia, open approach. 0JCL0ZZ................... Extirpation of matter from right upper leg subcutaneous tissue and fascia, open approach. 0JCM0ZZ................... Extirpation of matter from left upper leg subcutaneous tissue and fascia, open approach. 0JCN0ZZ................... Extirpation of matter from right lower leg subcutaneous tissue and fascia, open approach. 0JCP0ZZ................... Extirpation of matter from left lower leg subcutaneous tissue and fascia, open approach. 0JCQ0ZZ................... Extirpation of matter from right foot subcutaneous tissue and fascia, open approach. 0JCR0ZZ................... Extirpation of matter from left foot subcutaneous tissue and fascia, open approach. ------------------------------------------------------------------------ [[Page 41251]] The requestor stated that these procedures involve making an open incision deeper than the skin under general anesthesia, and that irrigation and/or excision of devitalized tissue or cavity are often required and are considered inherent to the procedure. The requestor also stated that open drainage of subcutaneous tissue and fascia, open excisional debridement of subcutaneous tissue and fascia, and open nonexcisional debridement/extraction of subcutaneous tissue and fascia are designated as O.R. procedures, and that these 22 procedures should be designated as O.R. procedures for the same reason. In the ICD-10 MS- DRGs Version 35, these 22 ICD-10-PCS procedure codes are not recognized as O.R. procedures for purposes of MS-DRG assignment. The requestor recommended that the 22 ICD-10-PCS procedure codes listed in the table be assigned to MS-DRGs 579, 580, and 581 (Other Skin, Subcutaneous Tissue and Breast Procedures with MCC, CC, and without CC/MCC, respectively). In the proposed rule, we stated that we disagreed with the requestor that these procedures typically require the resources of an operating room. Our clinical advisors indicated that these open extirpation procedures are minor procedures that can be performed outside of an operating room, such as in a radiology suite with CT or MRI guidance. We disagreed that these procedures are similar to open drainage procedures. Therefore, we proposed to maintain the status of these 22 ICD-10-PCS procedure codes as non-O.R. procedures. Comment: Some commenters supported the proposal to maintain the designation of the 22 identified procedure codes as non-O.R. procedures. One commenter opposed the proposal, stating that open extirpation procedures typically require the use of anesthesia and an operating room. This commenter stated that the 22 procedures are similar to open drainage, excisional debridement, and non-excisional debridement/extraction of subcutaneous tissue and fascia, which are designated as O.R. procedures. Response: We appreciate the commenters' support. In response to the commenter who opposed the proposal, our clinical advisors continue to believe that these open extirpation procedures are minor procedures that can be performed outside of an operating room, such as in a radiology suite with CT or MRI guidance, and therefore do not require the use of an operating room. Our clinical advisors further noted that the use of anesthesia frequently occurs in a CT or MRI suite. In addition, our clinical advisors continue to disagree with the assertion that these procedures are similar to open drainage procedures because fewer resources are required for open extirpation procedures relative to open drainage procedures and the open extirpation procedures are not usually performed in the operating room. After consideration of the public comments we received, we are finalizing our proposal to maintain the non-O.R. status of the 22 identified open extirpation procedures. c. Open Scrotum and Breast Procedures One requestor identified 13 ICD-10-PCS procedure codes that describe procedures involving open drainage, open extirpation, and open debridement/excision of the scrotum and breast. The requestor stated that the 13 procedures listed in the following table involve making an open incision deeper than the skin under general anesthesia, and that irrigation and/or excision of devitalized tissue or cavity are often required and are considered inherent to the procedure. The requestor also stated that open drainage of subcutaneous tissue and fascia, open excisional debridement of subcutaneous tissue and fascia, open non- excisional debridement/extraction of subcutaneous tissue and fascia, and open excision of breast are designated as O.R. procedures, and that these 13 procedures should be designated as O.R. procedures for the same reason. In the ICD-10 MS-DRGs Version 35, these 13 ICD-10-PCS procedure codes are not recognized as O.R. procedures for purposes of MS-DRG assignment. ------------------------------------------------------------------------ ICD-10-PCS procedure code Code description ------------------------------------------------------------------------ 0V950ZZ................... Drainage of scrotum, open approach. 0VB50ZZ................... Excision of scrotum, open approach. 0VC50ZZ................... Extirpation of matter from scrotum, open approach. 0H9U0ZZ................... Drainage of left breast, open approach. 0H9T0ZZ................... Drainage of right breast, open approach. 0H9V0ZZ................... Drainage of bilateral breast, open approach. 0H9W0ZZ................... Drainage of right nipple, open approach. 0H9X0ZZ................... Drainage of left nipple, open approach. 0HCT0ZZ................... Extirpation of matter from right breast, open approach. 0HCU0ZZ................... Extirpation of matter from left breast, open approach. 0HCV0ZZ................... Extirpation of matter from bilateral breast, open approach. 0HCW0ZZ................... Extirpation of matter from right nipple, open approach. 0HCX0ZZ................... Extirpation of matter from left nipple, open approach. ------------------------------------------------------------------------ The requestor recommended that the 3 ICD-10-PCS scrotal procedure codes be assigned to MS-DRGs 717 and 718 (Other Male Reproductive System O.R. Procedures Except Malignancy with CC/MCC and without CC/ MCC, respectively) and the 10 breast procedure codes be assigned to MS- DRGs 584 and 585 (Breast Biopsy, Local Excision and Other Breast Procedures with CC/MCC and without CC/MCC, respectively). In the proposed rule, we stated that we agreed with the requestor that these procedures typically require the resources of an operating room due to the nature of breast and scrotal tissue, as well as with the MS-DRG assignments recommended by the requestor. In addition, we stated that we believe that the scrotal codes should also be assigned to MS-DRGs 715 and 716 (Other Male Reproductive System O.R. Procedures for Malignancy with CC/MCC and without CC/MCC, respectively). Therefore, we proposed to add these 13 ICD-10-PCS procedure codes to the FY 2019 ICD-10 MS-DRGs Version 36 Definitions Manual in Appendix E--Operating Room Procedures and Procedure Code/MS-DRG Index as O.R. procedures, assigned to MS-DRGs 715, 716, 717, and 718 in MDC 12 (Diseases and Disorders of the Male Reproductive System) for the scrotal procedure codes and assigned to MS-DRGs 584 and 585 in MDC 9 (Diseases and Disorders of the Skin, [[Page 41252]] Subcutaneous Tissue & Breast) for the breast procedure codes. Comment: Commenters supported the proposal to change the designation of the 13 identified procedure codes to O.R. procedures. Response: We appreciate the commenters' support. After consideration of the public comments we received, we are finalizing our proposal to change the designation of the 13 ICD-10-PCS procedure codes shown in the table above from non-O.R. procedures to O.R. procedures, effective October 1, 2018. d. Open Parotid Gland and Submaxillary Gland Procedures One requestor identified eight ICD-10-PCS procedure codes that describe procedures involving open drainage and open extirpation of the parotid or submaxillary glands, shown in the following table. ------------------------------------------------------------------------ ICD-10-PCS procedure code Code description ------------------------------------------------------------------------ 0C980ZZ................... Drainage of right parotid gland, open approach. 0C990ZZ................... Drainage of left parotid gland, open approach. 0C9G0ZZ................... Drainage of right submaxillary gland, open approach. 0C9H0ZZ................... Drainage of left submaxillary gland, open approach. 0CC80ZZ................... Extirpation of matter from right parotid gland, open approach. 0CC90ZZ................... Extirpation of matter from left parotid gland, open approach. 0CCG0ZZ................... Extirpation of matter from right submaxillary gland, open approach. 0CCH0ZZ................... Extirpation of matter from left submaxillary gland, open approach. ------------------------------------------------------------------------ The requestor stated that these procedures involve making an open incision through subcutaneous tissue, fascia, and potentially muscle, to reach and incise the parotid or submaxillary gland under general anesthesia, and that irrigation and/or excision of devitalized tissue or cavity may be required and are considered inherent to the procedure. The requestor also stated that open drainage of subcutaneous tissue and fascia, open excisional debridement of subcutaneous tissue and fascia, and open non-excisional debridement/extraction of subcutaneous tissue and fascia are designated as O.R. procedures, and that these eight procedures should be designated as O.R. procedures for the same reason. In the ICD-10 MS-DRGs Version 35, these eight ICD-10-PCS procedure codes are not recognized as O.R. procedures for purposes of MS-DRG assignment. The requestor requested that these procedures be assigned to MS-DRG 139 (Salivary Gland Procedures). In the proposed rule, we stated that we agreed with the requestor that these eight procedures typically require the resources of an operating room. Therefore, we proposed to add these ICD-10-PCS procedure codes to the FY 2019 ICD-10 MS-DRGs Version 36 Definitions Manual in Appendix E--Operating Room Procedures and Procedure Code/MS- DRG Index as O.R. procedures assigned to MS-DRG 139 in MDC 3 (Diseases and Disorders of the Ear, Nose, Mouth and Throat). Comment: One commenter supported the proposal to change the designation of the 8 identified procedure codes to O.R. procedures. Response: We appreciate the commenter's support. After consideration of the public comments we received, we are finalizing our proposal to change the designation of the 8 ICD-10-PCS procedure codes shown in the table above from non-O.R. procedures to O.R. procedures, effective October 1, 2018. e. Removal and Reinsertion of Spacer; Knee Joint and Hip Joint One requestor identified four sets of ICD-10-PCS procedure code combinations (eight ICD-10-PCS codes) that describe procedures involving open removal and insertion of spacers into the knee or hip joints, shown in the following table. The requestor stated that these are invasive procedures involving removal and reinsertion of devices into major joints and are performed in the operating room under general anesthesia. In the ICD-10 MS-DRGs Version 35, these four ICD-10-PCS procedure code combinations are not recognized as O.R. procedures for purposes of MS-DRG assignment. The requestor recommended that CMS determine the most appropriate surgical DRGs for these procedures. ------------------------------------------------------------------------ ICD-10-PCS procedure code Code description ------------------------------------------------------------------------ 0SPC08Z........................ Removal of spacer from right knee joint, open approach. 0SHC08Z........................ Insertion of spacer into right knee joint, open approach. 0SPD08Z........................ Removal of spacer from left knee joint, open approach. 0SHD08Z........................ Insertion of spacer into left knee joint, open approach. 0SP908Z........................ Removal of spacer from right hip joint, open approach. 0SH908Z........................ Insertion of spacer into right hip joint, open approach. 0SPB08Z........................ Removal of spacer from left hip joint, open approach. 0SHB08Z........................ Insertion of spacer into left hip joint, open approach. ------------------------------------------------------------------------ In the proposed rule, we stated that we agreed with the requestor that these procedures typically require the resources of an operating room. However, our clinical advisors indicated that these codes should be designated as O.R. procedures even when reported as stand-alone procedures. Therefore, for the knee procedures, we proposed to add these four ICD-10-PCS procedure codes to the FY 2019 ICD-10 MS-DRGs Version 36 Definitions Manual in Appendix E--Operating Room Procedures and Procedure Code/MS-DRG Index as O.R. procedures assigned to MS-DRGs 485, 486, and 487 (Knee Procedures with Principal Diagnosis of Infection with MCC, with CC, and without CC/MCC, respectively) or MS- DRGs 488 and 489 (Knee Procedures without Principal diagnosis of Infection with CC/MCC and without CC/MCC, respectively), both in MDC 8 (Diseases and Disorders of the Musculoskeletal [[Page 41253]] System and Connective Tissue). For the hip procedures, we proposed to add these four ICD-10-PCS procedure codes to the FY 2019 ICD-10 MS-DRGs Version 36 Definitions Manual in Appendix E--Operating Room Procedures and Procedure Code/MS-DRG Index as O.R. procedures assigned to MS-DRGs 480, 481, and 482 (Hip and Femur Procedures Except Major Joint with MCC, with CC, and without CC/MCC, respectively) in MDC 8 (Diseases and Disorders of the Musculoskeletal System and Connective Tissue). Comment: Commenters supported the proposal to change the designation of the eight identified procedure codes to O.R. procedures. Several commenters who supported the proposal also requested that CMS ensure that changing the designation to O.R. procedures not have the unintended impact of reducing payment for these procedures. These commenters also requested that CMS clarify that the proposed MS-DRG assignments only apply when the eight codes are reported as stand-alone procedures and not, for example, when a spacer is removed and a permanent joint implant is inserted. One commenter stated that additional cost data would be useful in determining whether the payment for the proposed MS-DRGs fully reflect the O.R. resources used in these procedures. Response: We appreciate the commenters' support. With regard to the MS-DRG assignment, we are clarifying that, in all cases, the GROUPER logic would consider all of the procedures reported, the principal diagnosis, the surgical hierarchy, and the MS-DRG assignments for those procedures to determine the appropriate MS-DRG assignment. In cases where there is a procedure that is used for MS-DRG assignment that is higher in the surgical hierarchy, that procedure code would determine the MS-DRG assignment. In cases where the other procedure(s) are lower in the surgical hierarchy, the case would be assigned to the MS-DRGs listed above. With regard to the comments about the implications for payment and the cost data, we note that the goals of changing the designation of procedures from non-O.R. to O.R., or vice versa, are to better clinically represent the resources involved in caring for these patients and to enhance the overall accuracy of the system. Therefore, decisions to change an O.R. designation are based on whether such a change would accomplish those goals and not whether the change in designation would impact the payment in a particular direction. After consideration of the public comments we received, we are finalizing our proposal to change the designation of the eight ICD-10- PCS procedure codes shown in the table above from non-O.R. procedures to O.R. procedures, effective October 1, 2018. f. Endoscopic Dilation of Ureter(s) With Intraluminal Device One requestor identified the following three ICD-10-PCS procedure codes that describe procedures involving endoscopic dilation of ureter(s) with intraluminal device. ------------------------------------------------------------------------ ICD-10-PCS procedure code Code description ------------------------------------------------------------------------ 0T778DZ................... Dilation of left ureter with intraluminal device, via natural or artificial opening endoscopic. 0T768DZ................... Dilation of right ureter with intraluminal device, via natural or artificial opening endoscopic. 0T788DZ................... Dilation of bilateral ureters with intraluminal device, via natural or artificial opening endoscopic. ------------------------------------------------------------------------ The requestor stated that these procedures involve the use of cystoureteroscopy to view the bladder and ureter and dilation under visualization, which are often followed by placement of a ureteral stent. The requestor also stated that endoscopic extirpation of matter from ureter, endoscopic biopsy of bladder, endoscopic dilation of bladder, endoscopic dilation of renal pelvis, and endoscopic dilation of the ureter without insertion of intraluminal device are all assigned to surgical DRGs, and that these three procedures should be designated as O.R. procedures for the same reason. In the ICD-10 MS-DRGs Version 35, these three ICD-10-PCS procedure codes are not recognized as O.R. procedures for purposes of MS-DRG assignment. The requestor recommended that these procedures be assigned to MS-DRGs 656, 657, and 658 (Kidney and Ureter Procedures for Neoplasm with MCC, with CC, and without CC/ MCC, respectively) and MS-DRGs 659, 660, and 661 (Kidney and Ureter Procedures for Non-Neoplasm with MCC, with CC, and without CC/MCC, respectively). In the proposed rule, we stated that we agreed with the requestor that these procedures typically require the resources of an operating room. In addition to the MS-DRGs recommended by the requestor, we further stated that we believe that these procedure codes should also be assigned to other MS-DRGs, consistent with the assignment of other dilation of ureter procedures: MS-DRG 907, 908, and 909 (Other O.R. Procedures for Injuries with MCC, with CC, and without CC/MCC, respectively) and MS-DRGs 957, 958, and 959 (Other O.R. Procedures for Multiple Significant Trauma with MCC, with CC, and without CC/MCC, respectively). Therefore, we proposed to add the three ICD-10-PCS procedure codes identified by the requestor to the FY 2019 ICD-10 MS- DRGs Version 36 Definitions Manual in Appendix E--Operating Room Procedures and Procedure Code/MS-DRG Index as O.R. procedures assigned to MS-DRGs 656, 657, and 658 in MDC 11 (Diseases and Disorders of the Kidney and Urinary Tract), MS-DRGs 659, 660, and 661 in MDC 11, MS-DRGs 907, 908, and 909 in MDC 21 (Injuries, Poisonings and Toxic Effects of Drugs), and MS-DRGs 957, 958, and 959 in MDC 24 (Multiple Significant Trauma). Comment: One commenter supported the proposal to change the designation of the three identified procedure codes to O.R. procedures. Response: We appreciate the commenter's support. After consideration of the public comments we received, we are finalizing our proposal to change the designation of the three ICD-10- PCS procedure codes shown in the table above from non-O.R. procedures to O.R. procedures, effective October 1, 2018. g. Thoracoscopic Procedures of Pericardium and Pleura One requestor identified seven ICD-10-PCS procedure codes that describe procedures involving thoracoscopic drainage of the pericardial cavity or pleural cavity, or extirpation of matter from the pleura, as shown in the following table. [[Page 41254]] ------------------------------------------------------------------------ ICD-10-PCS procedure code Code description ------------------------------------------------------------------------ 0W9D4ZZ................... Drainage of pericardial cavity, percutaneous endoscopic approach. 0W9D40Z................... Drainage of pericardial cavity with drainage device, percutaneous endoscopic approach. 0W9D4ZX................... Drainage of pericardial cavity, percutaneous endoscopic approach, diagnostic. 0W994ZX................... Drainage of right pleural cavity, percutaneous endoscopic approach, diagnostic. 0W9B4ZX................... Drainage of left pleural cavity, percutaneous endoscopic approach, diagnostic. 0BCP4ZZ................... Extirpation of matter from left pleura, percutaneous endoscopic approach. 0BCN4ZZ................... Extirpation of matter from right pleura, percutaneous endoscopic approach. ------------------------------------------------------------------------ The requestor stated that these procedures involve making an incision through the chest wall and inserting a thoracoscope for visualization of thoracic structures during the procedure. The requestor also stated that some thoracoscopic procedures are assigned to surgical MS-DRGs, while other procedures are assigned to medical MS- DRGs. In the ICD-10 MS-DRGs Version 35, these seven ICD-10-PCS procedure codes are not recognized as O.R. procedures for purposes of MS-DRG assignment. In the proposed rule, we stated that we agreed with the requestor that these procedures typically require the resources of an operating room, as well as significant time and skill. During our review, we noted that the following two related procedures using the open approach also were not currently recognized as O.R. procedures: ------------------------------------------------------------------------ ICD-10-PCS procedure code Code description ------------------------------------------------------------------------ 0BCP0ZZ........................ Extirpation of matter from left pleura, open approach. 0BCN0ZZ........................ Extirpation of matter from right pleura, open approach. ------------------------------------------------------------------------ Therefore, to be consistent with the MS-DRGs to which other approaches for procedures involving drainage or extirpation of matter from the pleura are assigned, we proposed to add these nine ICD-10-PCS procedure codes to the FY 2019 ICD-10 MS-DRGs Version 36 Definitions Manual in Appendix E--Operating Room Procedures and Procedure Code/MS- DRG Index as O.R. procedures assigned to one of the following MS-DRGs: MS-DRGs 163, 164, and 165 (Major Chest Procedures with MCC, with CC, and without CC/MCC, respectively) in MDC 4 (Diseases and Disorders of the Respiratory System); MS-DRGs 270, 271, and 272 (Other Major Cardiovascular Procedures with MCC, with CC, and without CC/MCC, respectively) in MDC 5 (Diseases and Disorders of the Circulatory System); MS-DRGs 820, 821, and 822 (Lymphoma and Leukemia with Major O.R. Procedure with MCC, with CC, and without CC/MCC, respectively) in MDC 17 (Myeloproliferative Diseases and Disorders, Poorly Differentiated Neoplasms); MS-DRGs 826, 827, and 828 (Myeloproliferative Disorders or Poorly Differentiated Neoplasms with Major O.R. Procedure with MCC, with CC, and without CC/MCC, respectively) in MDC 17; MS-DRGs 907, 908, and 909 (Other O.R. Procedures for Injuries with MCC, with CC, and without CC/MCC, respectively) in MDC 21 (Injuries, Poisonings and Toxic Effects of Drugs); and MS-DRGs 957, 958, and 959 (Other O.R. Procedures for Multiple Significant Trauma with MCC, with CC, and without CC/MCC, respectively) in MDC 24 (Multiple Significant Trauma). We invited public comments on our proposal. Comment: One commenter supported the proposal to change the designation of the nine identified procedure codes to O.R. procedures. Response: We appreciate the commenter's support. After consideration of the public comments we received, we are finalizing our proposal to change the designation of the nine ICD-10- PCS procedure codes shown in the tables above from non-O.R. procedures to O.R. procedures, effective October 1, 2018. h. Open Insertion of Totally Implantable and Tunneled Vascular Access Devices One requestor identified 20 ICD-10-PCS procedure codes that describe procedures involving open insertion of totally implantable and tunneled vascular access devices. The codes are identified in the following table. ------------------------------------------------------------------------ ICD-10-PCS procedure code Code description ------------------------------------------------------------------------ 0JH60WZ................... Insertion of totally implantable vascular access device into chest subcutaneous tissue and fascia, open approach. 0JH60XZ................... Insertion of tunneled vascular access device into chest subcutaneous tissue and fascia, open approach. 0JH80WZ................... Insertion of totally implantable vascular access device into abdomen subcutaneous tissue and fascia, open approach. 0JH80XZ................... Insertion of tunneled vascular access device into abdomen subcutaneous tissue and fascia, open approach. 0JHD0WZ................... Insertion of totally implantable vascular access device into right upper arm subcutaneous tissue and fascia, open approach. 0JHD0XZ................... Insertion of tunneled vascular access device into right upper arm subcutaneous tissue and fascia, open approach. 0JHF0WZ................... Insertion of totally implantable vascular access device into left upper arm subcutaneous tissue and fascia, open approach. 0JHF0XZ................... Insertion of tunneled vascular access device into left upper arm subcutaneous tissue and fascia, open approach. 0JHG0WZ................... Insertion of totally implantable vascular access device into right lower arm subcutaneous tissue and fascia, open approach. 0JHG0XZ................... Insertion of tunneled vascular access device into right lower arm subcutaneous tissue and fascia, open approach. 0JHH0WZ................... Insertion of totally implantable vascular access device into left lower arm subcutaneous tissue and fascia, open approach. 0JHH0XZ................... Insertion of tunneled vascular access device into left lower arm subcutaneous tissue and fascia, open approach. 0JHL0WZ................... Insertion of totally implantable vascular access device into right upper leg subcutaneous tissue and fascia, open approach. 0JHL0XZ................... Insertion of tunneled vascular access device into right upper leg subcutaneous tissue and fascia, open approach. 0JHM0WZ................... Insertion of totally implantable vascular access device into left upper leg subcutaneous tissue and fascia, open approach. 0JHM0XZ................... Insertion of tunneled vascular access device into left upper leg subcutaneous tissue and fascia, open approach. 0JHN0WZ................... Insertion of totally implantable vascular access device into right lower leg subcutaneous tissue and fascia, open approach. [[Page 41255]] 0JHN0XZ................... Insertion of tunneled vascular access device into right lower leg subcutaneous tissue and fascia, open approach. 0JHP0WZ................... Insertion of totally implantable vascular access device into left lower leg subcutaneous tissue and fascia, open approach. 0JHP0XZ................... Insertion of tunneled vascular access device into left lower leg subcutaneous tissue and fascia, open approach. ------------------------------------------------------------------------ The requestor stated that open procedures to insert totally implantable vascular access devices (VAD) involve implantation of a port by open approach, cutting through subcutaneous tissue/fascia, placing the device, and then closing tissues so that none of the device is exposed. The requestor explained that open procedures to insert tunneled VADs involve insertion of the catheter into central vasculature, and then open incision of subcutaneous tissue and fascia through which the device is tunneled. The requestor also indicated that these procedures require two ICD-10-PCS codes: One for the insertion of the VAD or port within the subcutaneous tissue; and one for percutaneous insertion of the central venous catheter that is connected to the device. The requestor further noted that, in MDC 11, cases with these procedure codes are assigned to surgical MS-DRGs and that insertion of infusion pumps by open approach groups to surgical MS- DRGs. The requestor recommended that these procedures be assigned to surgical MS-DRGs in MDC 09 as well. We examined the O.R. designations for this group of procedures and determined that they currently are designated as non-O.R. procedures for MDC 09 and MDC 11. In the proposed rule, we stated that we agreed with the requestor that procedures involving open insertion of totally implantable VAD procedures typically require the resources of an operating room. However, we stated that we disagreed that the tunneled VAD procedures typically require the resources of an operating room. Therefore, we proposed to update the FY 2019 ICD-10 MS-DRGs Version 36 Definitions Manual in Appendix E--Operating Room Procedures and Procedure Code/MS- DRG Index to designate the 10 ICD-10-PCS procedure codes describing the totally implantable VAD procedures as O.R. procedures, which will continue to be assigned to MS-DRGs 579, 580, and 581 (Other Skin, Subcutaneous Tissue and Breast Procedures with MCC, with CC, and without CC/MCC, respectively) in MDC 9 (Diseases and Disorders of the Skin, Subcutaneous Tissue and Breast) and MS-DRGs 673, 674, and 675 (Other Kidney and Urinary Tract Procedures, with CC, with MCC, and without CC/MCC, respectively) in MDC 11 (Diseases and Disorders of the Kidney and Urinary Tract). We noted that these procedures already affect MS-DRG assignment to these MS-DRGs. However, we stated that if the procedure is unrelated to the principal diagnosis, it will be assigned to MS-DRGs 981, 982, and 983 instead of a medical MS-DRG. Comment: Commenters supported the proposal to change the designation of the open insertion of totally implantable VAD procedures to O.R. procedures. One commenter requested that CMS reconsider the GROUPER logic to add totally implantable VADs to additional MDCs, and not just MDCs 9 and 11. Response: We appreciate the commenters' support. With regard to the GROUPER logic, we will consider whether procedures should be added to additional MDCs during our annual assessment of the codes that group to the unrelated procedure MS-DRGs, which is discussed later in this section of the preamble of this final rule. After consideration of the public comments we received, we are finalizing our proposal to change the designation of the 10 ICD-10-PCS procedure codes describing open insertion of totally implantable VAD procedures shown in the table above from non-O.R. procedures to O.R. procedures, effective October 1, 2018. Comment: Some commenters supported the proposal to maintain the non-O.R. assignment of the tunneled VAD procedures listed in the table above, while others opposed this proposal. The commenters who opposed the proposal stated that tunneled VAD procedures involve significantly more resources than non-tunneled catheters because of the significant subcutaneous tunneling required. The commenters also noted that the procedures require the specialized setting of an operating room or interventional radiology suite. The commenters explained the following aspects of the technique that they believe indicate that the procedures should be designated as O.R. procedures: A small incision is typically made and one end of the catheter is advanced into the internal jugular vein, and threaded into the superior/inferior vena cava, or right atrium under fluoroscopic guidance. The other end of the catheter is tunneled beneath the skin and subcutaneous tissue and a small incision is made at the exit site on the chest. A small cuff is sometimes anchored to the skin to stabilize and prevent infection. While the tunneled VADs are typically performed with small incisions, the subcutaneous tunneling is the most complex portion of the procedure. In addition, one commenter listed additional tunneled VAD codes (performed on other body parts, such as the arms and legs) that should also be considered for a change to the O.R. designation. Response: Our clinical advisors continue to believe that tunneled VAD procedures do not typically require the use of an operating room. As the commenter stated, these procedures are frequently performed under image guidance, which our clinical advisors believe would typically take place in a radiology suite. Our clinical advisors believe that the list of other VAD procedures cited by the commenter would also typically take place in the radiology suite and, therefore, would not typically require the use of an operating room. Therefore, we are not making a change to the O.R. designation of the codes suggested by the commenter. After consideration of the public comments we received, we are finalizing our proposals to change the designation of the totally implantable VAD procedures to O.R. procedures and to maintain the non- O.R. designation of the tunneled VAD procedures. i. Percutaneous Joint Reposition With Internal Fixation Device One requestor identified 20 ICD-10-PCS procedure codes that describe procedures involving percutaneous joint reposition with internal fixation device, shown in the following table. [[Page 41256]] ------------------------------------------------------------------------ ICD-10-PCS procedure code Code description ------------------------------------------------------------------------ 0SS034Z................... Reposition lumbar vertebral joint with internal fixation device, percutaneous approach. 0SS334Z................... Reposition lumbosacral joint with internal fixation device, percutaneous approach. 0SS534Z................... Reposition sacrococcygeal joint with internal fixation device, percutaneous approach. 0SS634Z................... Reposition coccygeal joint with internal fixation device, percutaneous approach. 0SS734Z................... Reposition right sacroiliac joint with internal fixation device, percutaneous approach. 0SS834Z................... Reposition left sacroiliac joint with internal fixation device, percutaneous approach. 0SS934Z................... Reposition right hip joint with internal fixation device, percutaneous approach. 0SSB34Z................... Reposition left hip joint with internal fixation device, percutaneous approach. 0SSC34Z................... Reposition right knee joint with internal fixation device, percutaneous approach. 0SSD34Z................... Reposition left knee joint with internal fixation device, percutaneous approach. 0SSF34Z................... Reposition right ankle joint with internal fixation device, percutaneous approach. 0SSG34Z................... Reposition left ankle joint with internal fixation device, percutaneous approach. 0SSH34Z................... Reposition right tarsal joint with internal fixation device, percutaneous approach. 0SSJ34Z................... Reposition left tarsal joint with internal fixation device, percutaneous approach. 0SSK34Z................... Reposition right tarsometatarsal joint with internal fixation device, percutaneous approach. 0SSL34Z................... Reposition left tarsometatarsal joint with internal fixation device, percutaneous approach. 0SSM34Z................... Reposition right metatarsal-phalangeal joint with internal fixation device, percutaneous approach. 0SSN34Z................... Reposition left metatarsal-phalangeal joint with internal fixation device, percutaneous approach. 0SSP34Z................... Reposition right toe phalangeal joint with internal fixation device, percutaneous approach. 0SSQ34Z................... Reposition left toe phalangeal joint with internal fixation device, percutaneous approach. ------------------------------------------------------------------------ The requestor stated that reposition of the sacrum, femur, tibia, fibula, and other fractures of bone with internal fixation device by percutaneous approach are assigned to surgical DRGs, and that reposition of sacroiliac, hip, knee, and other joint locations with internal fixation should therefore also be assigned to surgical DRGs. In the ICD-10 MS-DRGs Version 35, these 20 ICD-10-PCS procedure codes are not recognized as O.R. procedures for purposes of MS-DRG assignment. In the proposed rule, we stated that we disagreed with the requestor that these procedures typically require the resources of an operating room, as these procedures are not as invasive as the bone reposition procedures referenced by the requestor. Our clinical advisors advised that these procedures are typically performed in a radiology suite. Therefore, we proposed to maintain the status of these 20 ICD-10-PCS procedure codes as non-O.R. procedures. Comment: Some commenters supported the proposal to maintain the status of the 20 ICD-10-PCS procedure codes that describe procedures involving percutaneous joint reposition with internal fixation device listed in the table above, while one commenter opposed our proposal. The commenter who opposed the proposal stated that these procedures are often done under image guidance, but that they are typically done in the operating room because they require anesthesia. The commenter stated that these procedures involving dislocated joints are even more resource intensive than fracture treatment involving a single bone, which are classified as O.R. procedures. Response: Our clinical advisors continue to believe that the resources involved in furnishing these procedures are consistent with non-O.R. procedures, given that they are typically done with imaging guidance. Our clinical advisors noted that it is not uncommon for anesthesia to be used in the radiology suite, and that the nature of the resources used in repositioning displaced joints do not require the use of an operating room. After consideration of the public comments we received, we are finalizing our proposal to maintain the non-O.R. status of the 20 ICD- 10-PCS procedure codes that describe procedures involving percutaneous joint reposition with internal fixation device listed in the table above. j. Endoscopic Destruction of Intestine One requestor identified four ICD-10-PCS procedure codes that describe procedures involving endoscopic destruction of the intestine, as shown in the following table. ------------------------------------------------------------------------ ICD-10-PCS procedure code Code description ------------------------------------------------------------------------ 0D5A8ZZ................... Destruction of jejunum, via natural or artificial opening endoscopic. 0D5B8ZZ................... Destruction of ileum, via natural or artificial opening endoscopic. 0D5C8ZZ................... Destruction of ileocecal valve, via natural or artificial opening endoscopic. 0D588ZZ................... Destruction of small intestine, via natural or artificial opening endoscopic. ------------------------------------------------------------------------ The requestor stated that these procedures are rarely performed in the operating room. In the ICD-10 MS-DRGs Version 35, these four ICD- 10-PCS procedure codes are currently recognized as O.R. procedures for purposes of MS-DRG assignment. In the proposed rule, we stated that we agreed with the requestor that these procedures do not typically require the resources of an operating room. Therefore, we proposed to remove these four procedure codes from the FY 2019 ICD-10 MS-DRGs Version 36 Definitions Manual in Appendix E--Operating Room Procedures and Procedure Code/MS-DRG Index as O.R. procedures. Comment: One commenter supported the proposal to change the designation of the four identified procedure codes to non-O.R. procedures. Response: We appreciate the commenter's support. After consideration of the public comments we received, we are finalizing our proposal to change the designation of the four ICD-10- PCS procedure codes shown in the table above from O.R. procedures to non-O.R. procedures, effective October 1, 2018. [[Page 41257]] k. Drainage of Lower Lung Via Natural or Artificial Opening Endoscopic, Diagnostic One requestor identified the following ICD-10-PCS procedure codes that describe procedures involving endoscopic drainage of the lung via natural or artificial opening for diagnostic purposes. ------------------------------------------------------------------------ ICD-10-PCS procedure code Code description ------------------------------------------------------------------------ 0B9J8ZX................... Drainage of left lower lung lobe, via natural or artificial opening endoscopic, diagnostic. 0B9F8ZX................... Drainage of right lower lung lobe, via natural or artificial opening endoscopic, diagnostic. ------------------------------------------------------------------------ The requestor stated that these procedures are rarely performed in the operating room. In the proposed rule, we stated that we agreed with the requestor that these procedures do not require the resources of an operating room. In addition, while we were reviewing this comment, we identified three additional related codes: ------------------------------------------------------------------------ ICD-10-PCS procedure code Code description ------------------------------------------------------------------------ 0B9D8ZX................... Drainage of right middle lung lobe, via natural or artificial opening endoscopic, diagnostic. 0B9C8ZX................... Drainage of right upper lung lobe, via natural or artificial opening endoscopic, diagnostic. 0B9G8ZX................... Drainage of left upper lung lobe, via natural or artificial opening endoscopic, diagnostic. ------------------------------------------------------------------------ In the ICD-10 MS-DRGs Version 35, these ICD-10-PCS procedure codes are currently recognized as O.R. procedures for purposes of MS-DRG assignment. We proposed to remove ICD-10-PCS procedure codes 0B9J8ZX, 0B9F8ZX, 0B9D8ZX, 0B9C8ZX, and 0B9G8ZX from the FY 2019 ICD-10 MS-DRGs Version 36 Definitions Manual in Appendix E--Operating Room Procedures and Procedure Code/MS-DRG Index as O.R. procedures. Comment: One commenter supported the proposal to change the designation of the five identified procedure codes to non-O.R. procedures. Response: We appreciate the commenter's support. After consideration of the public comments we received, we are finalizing our proposal to change the designation of the five ICD-10- PCS procedure codes shown in the tables above from O.R. procedures to non-O.R. procedures, effective October 1, 2018. l. Endobronchial Valve Procedures One commenter responding to the FY 2019 IPPS/LTCH PPS proposed rule identified eight ICD-10-PCS procedure codes that describe endobronchial valve procedures that the commenter believed should be designated as O.R. procedures. The codes are identified in the following table. ------------------------------------------------------------------------ ICD-10-PCS procedure code Code description ------------------------------------------------------------------------ 0BH38GZ................... Insertion of endobronchial valve into right main bronchus, via natural or artificial opening endoscopic. 0BH48GZ................... Insertion of endobronchial valve into right upper lobe bronchus, via natural or artificial opening endoscopic. 0BH58GZ................... Insertion of endobronchial valve into right middle lobe bronchus, via natural or artificial opening endoscopic. 0BH68GZ................... Insertion of endobronchial valve into right lower lobe bronchus, via natural or artificial opening endoscopic. 0BH78GZ................... Insertion of endobronchial valve into left main bronchus, via natural or artificial opening endoscopic. 0BH88GZ................... Insertion of endobronchial valve into left upper lobe bronchus, via natural or artificial opening endoscopic. 0BH98GZ................... Insertion of endobronchial valve into lingula bronchus, via natural or artificial opening endoscopic. 0BHB8GZ................... Insertion of endobronchial valve into left lower lobe bronchus, via natural or artificial opening endoscopic. ------------------------------------------------------------------------ The commenter stated that these procedures are most commonly performed in the O.R., given the need for better monitoring and support through the process of identifying and occluding a prolonged air leak using endobronchial valve technology. The commenter also noted that other endobronchial valve procedures have an O.R. designation. In the ICD-10 MS-DRGs Version 35, these eight ICD-10-PCS procedure codes are not recognized as O.R. procedures for purposes of MS-DRG assignment. The commenter requested that these eight codes be assigned to MS-DRG 163 (Major Chest Procedures with MCC) due to similar cost and resource use. Our clinical advisors disagree with the commenter that the eight identified procedures typically require the use of an operating room. Our clinical advisors believe that these procedures would typically be performed in an endoscopy suite. Therefore, we are not changing the non-O.R. designation of the eight identified ICD-10-PCS codes listed in the table above. 21. Out of Scope Public Comments Received We received public comments regarding a number of MS-DRG and related issues that were outside the scope of the proposals included in the FY 2019 IPPS/LTCH PPS proposed rule. These comments were as follows: One commenter requested that CMS evaluate the MS-DRG assignment for Face Transplant procedures and its designation as an extensive versus nonextensive O.R. procedure. One commenter requested that a new ICD-10-CM diagnosis code be created for a Kennedy terminal ulcer. One commenter requested that CMS examine the MS-DRG assignment and/or payment of patients who are admitted to the hospital for initiation or titration of certain antiarrhythmic drugs. One commenter requested that diagnosis codes in category O9A.2- and [[Page 41258]] O9A.3- for obstetrical patients be considered as a principal diagnosis for MDC 24 (Multiple Significant Trauma). One commenter requested that new MS-DRGs be created for endovascular cardiac valve replacements with and without a cardiac catheterization. One commenter recommended that CMS analyze claims data for cases reporting renal replacement therapy and issue guidance to facilities on the use of the ICD-10-PCS procedure codes. One commenter requested specific MS-DRG assignments for ICD-10-PCS codes that were not yet approved at the time of issuance of the proposed rule. One commenter recommended changes to the severity level designation for diagnosis codes that appear in Table 6E.--Revised Diagnosis Code Titles associated with the proposed rule. Because we consider these public comments to be outside the scope of the proposed rule, we are not addressing them in this final rule. As stated in section II.F.1.b. of the preamble of this final rule, we encourage individuals with comments about MS-DRG classification to submit these comments no later than November 1 of each year so that they can be considered for possible inclusion in the annual proposed rule and, if included, may be subjected to public review and comment. We will consider these public comments for possible proposals in future rulemaking as part of our annual review process. G. Recalibration of the FY 2019 MS-DRG Relative Weights 1. Data Sources for Developing the Relative Weights In developing the FY 2019 system of weights, we proposed to use two data sources: Claims data and cost report data. As in previous years, the claims data source is the MedPAR file. This file is based on fully coded diagnostic and procedure data for all Medicare inpatient hospital bills. The FY 2017 MedPAR data used in this final rule include discharges occurring on October 1, 2016, through September 30, 2017, based on bills received by CMS through March 31, 2018, from all hospitals subject to the IPPS and short-term, acute care hospitals in Maryland (which at that time were under a waiver from the IPPS). The FY 2017 MedPAR file used in calculating the relative weights includes data for approximately 9,689,743 Medicare discharges from IPPS providers. Discharges for Medicare beneficiaries enrolled in a Medicare Advantage managed care plan are excluded from this analysis. These discharges are excluded when the MedPAR ``GHO Paid'' indicator field on the claim record is equal to ``1'' or when the MedPAR DRG payment field, which represents the total payment for the claim, is equal to the MedPAR ``Indirect Medical Education (IME)'' payment field, indicating that the claim was an ``IME only'' claim submitted by a teaching hospital on behalf of a beneficiary enrolled in a Medicare Advantage managed care plan. In addition, the March 31, 2018 update of the FY 2017 MedPAR file complies with version 5010 of the X12 HIPAA Transaction and Code Set Standards, and includes a variable called ``claim type.'' Claim type ``60'' indicates that the claim was an inpatient claim paid as fee-for- service. Claim types ``61,'' ``62,'' ``63,'' and ``64'' relate to encounter claims, Medicare Advantage IME claims, and HMO no-pay claims. Therefore, the calculation of the relative weights for FY 2019 also excludes claims with claim type values not equal to ``60.'' The data exclude CAHs, including hospitals that subsequently became CAHs after the period from which the data were taken. We note that the FY 2019 relative weights are based on the ICD-10-CM diagnoses and ICD-10-PCS procedure codes from the FY 2017 MedPAR claims data, grouped through the ICD-10 version of the FY 2019 GROUPER (Version 36). The second data source used in the cost-based relative weighting methodology is the Medicare cost report data files from the HCRIS. Normally, we use the HCRIS dataset that is 3 years prior to the IPPS fiscal year. Specifically, we used cost report data from the March 31, 2018 update of the FY 2016 HCRIS for calculating the final FY 2019 cost-based relative weights. 2. Methodology for Calculation of the Relative Weights As we explain in section II.E.2. of the preamble of this final rule, we calculated the FY 2019 relative weights based on 19 CCRs, as we did for FY 2018. The methodology we used to calculate the FY 2019 MS-DRG cost-based relative weights based on claims data in the FY 2017 MedPAR file and data from the FY 2016 Medicare cost reports is as follows: To the extent possible, all the claims were regrouped using the FY 2019 MS-DRG classifications discussed in sections II.B. and II.F. of the preamble of this final rule. The transplant cases that were used to establish the relative weights for heart and heart-lung, liver and/or intestinal, and lung transplants (MS-DRGs 001, 002, 005, 006, and 007, respectively) were limited to those Medicare-approved transplant centers that have cases in the FY 2017 MedPAR file. (Medicare coverage for heart, heart- lung, liver and/or intestinal, and lung transplants is limited to those facilities that have received approval from CMS as transplant centers.) Organ acquisition costs for kidney, heart, heart-lung, liver, lung, pancreas, and intestinal (or multivisceral organs) transplants continue to be paid on a reasonable cost basis. Because these acquisition costs are paid separately from the prospective payment rate, it is necessary to subtract the acquisition charges from the total charges on each transplant bill that showed acquisition charges before computing the average cost for each MS-DRG and before eliminating statistical outliers. Claims with total charges or total lengths of stay less than or equal to zero were deleted. Claims that had an amount in the total charge field that differed by more than $30.00 from the sum of the routine day charges, intensive care charges, pharmacy charges, implantable devices charges, supplies and equipment charges, therapy services charges, operating room charges, cardiology charges, laboratory charges, radiology charges, other service charges, labor and delivery charges, inhalation therapy charges, emergency room charges, blood and blood products charges, anesthesia charges, cardiac catheterization charges, CT scan charges, and MRI charges were also deleted. At least 92.5 percent of the providers in the MedPAR file had charges for 14 of the 19 cost centers. All claims of providers that did not have charges greater than zero for at least 14 of the 19 cost centers were deleted. In other words, a provider must have no more than five blank cost centers. If a provider did not have charges greater than zero in more than five cost centers, the claims for the provider were deleted. Statistical outliers were eliminated by removing all cases that were beyond 3.0 standard deviations from the geometric mean of the log distribution of both the total charges per case and the total charges per day for each MS-DRG. Effective October 1, 2008, because hospital inpatient claims include a POA indicator field for each diagnosis present on the claim, only for purposes of relative weight-setting, the POA indicator field was reset to ``Y'' for ``Yes'' for all claims that otherwise have an ``N'' (No) or a ``U'' (documentation insufficient to determine if the condition was present at the time of inpatient admission) in the POA field. [[Page 41259]] Under current payment policy, the presence of specific HAC codes, as indicated by the POA field values, can generate a lower payment for the claim. Specifically, if the particular condition is present on admission (that is, a ``Y'' indicator is associated with the diagnosis on the claim), it is not a HAC, and the hospital is paid for the higher severity (and, therefore, the higher weighted MS-DRG). If the particular condition is not present on admission (that is, an ``N'' indicator is associated with the diagnosis on the claim) and there are no other complicating conditions, the DRG GROUPER assigns the claim to a lower severity (and, therefore, the lower weighted MS-DRG) as a penalty for allowing a Medicare inpatient to contract a HAC. While the POA reporting meets policy goals of encouraging quality care and generates program savings, it presents an issue for the relative weight-setting process. Because cases identified as HACs are likely to be more complex than similar cases that are not identified as HACs, the charges associated with HAC cases are likely to be higher as well. Therefore, if the higher charges of these HAC claims are grouped into lower severity MS-DRGs prior to the relative weight-setting process, the relative weights of these particular MS-DRGs would become artificially inflated, potentially skewing the relative weights. In addition, we want to protect the integrity of the budget neutrality process by ensuring that, in estimating payments, no increase to the standardized amount occurs as a result of lower overall payments in a previous year that stem from using weights and case-mix that are based on lower severity MS-DRG assignments. If this would occur, the anticipated cost savings from the HAC policy would be lost. To avoid these problems, we reset the POA indicator field to ``Y'' only for relative weight-setting purposes for all claims that otherwise have an ``N'' or a ``U'' in the POA field. This resetting ``forced'' the more costly HAC claims into the higher severity MS-DRGs as appropriate, and the relative weights calculated for each MS-DRG more closely reflect the true costs of those cases. In addition, in the FY 2013 IPPS/LTCH PPS final rule, for FY 2013 and subsequent fiscal years, we finalized a policy to treat hospitals that participate in the Bundled Payments for Care Improvement (BPCI) initiative the same as prior fiscal years for the IPPS payment modeling and ratesetting process without regard to hospitals' participation within these bundled payment models (77 FR 53341 through 53343). Specifically, because acute care hospitals participating in the BPCI Initiative still receive IPPS payments under section 1886(d) of the Act, we include all applicable data from these subsection (d) hospitals in our IPPS payment modeling and ratesetting calculations as if the hospitals were not participating in those models under the BPCI Initiative. We refer readers to the FY 2013 IPPS/LTCH PPS final rule for a complete discussion on our final policy for the treatment of hospitals participating in the BPCI Initiative in our ratesetting process. The participation of hospitals in the BPCI initiative is set to conclude on September 30, 2018. The participation of hospitals in the Bundled Payments for Care Improvement (BPCI) Advanced model is set to start on October 1, 2018. The BPCI Advanced model, tested under the authority of section 3021 of the Affordable Care Act (codified at section 1115A of the Act), is comprised of a single payment and risk track, which bundles payments for multiple services beneficiaries receive during a Clinical Episode. Acute care hospitals may participate in BPCI Advanced in one of two capacities: As a model Participant or as a downstream Episode Initiator. Regardless of the capacity in which they participate in the BPCI Advanced model, participating acute care hospitals will continue to receive IPPS payments under section 1886(d) of the Act. Acute care hospitals that are Participants also assume financial and quality performance accountability for Clinical Episodes in the form of a reconciliation payment. For additional information on the BPCI Advanced model, we refer readers to the BPCI Advanced web page on the CMS Center for Medicare and Medicaid Innovation's website at: https://innovation.cms.gov/initiatives/bpci-advanced/. As we stated in the proposed rule, for FY 2019, consistent with how we have treated hospitals that participated in the BPCI Initiative, we believe it is appropriate to include all applicable data from the subsection (d) hospitals participating in the BPCI Advanced model in our IPPS payment modeling and ratesetting calculations because, as noted above and in the proposed rule, these hospitals are still receiving IPPS payments under section 1886(d) of the Act. The charges for each of the 19 cost groups for each claim were standardized to remove the effects of differences in area wage levels, IME and DSH payments, and for hospitals located in Alaska and Hawaii, the applicable cost-of-living adjustment. Because hospital charges include charges for both operating and capital costs, we standardized total charges to remove the effects of differences in geographic adjustment factors, cost-of-living adjustments, and DSH payments under the capital IPPS as well. Charges were then summed by MS-DRG for each of the 19 cost groups so that each MS-DRG had 19 standardized charge totals. Statistical outliers were then removed. These charges were then adjusted to cost by applying the national average CCRs developed from the FY 2016 cost report data. The 19 cost centers that we used in the relative weight calculation are shown in the following table. The table shows the lines on the cost report and the corresponding revenue codes that we used to create the 19 national cost center CCRs. In the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20259), we stated that if stakeholders have comments about the groupings in this table, we may consider those comments as we finalize our policy. However, we did not receive any comments on the groupings in this table, and therefore, we are finalizing the groupings as proposed. BILLING CODE 4120-01-P [[Page 41260]] [GRAPHIC] [TIFF OMITTED] TR17AU18.002 [[Page 41261]] [GRAPHIC] [TIFF OMITTED] TR17AU18.003 [[Page 41262]] [GRAPHIC] [TIFF OMITTED] TR17AU18.004 [[Page 41263]] [GRAPHIC] [TIFF OMITTED] TR17AU18.005 [[Page 41264]] [GRAPHIC] [TIFF OMITTED] TR17AU18.006 [[Page 41265]] [GRAPHIC] [TIFF OMITTED] TR17AU18.007 [[Page 41266]] [GRAPHIC] [TIFF OMITTED] TR17AU18.008 [[Page 41267]] [GRAPHIC] [TIFF OMITTED] TR17AU18.009 [[Page 41268]] [GRAPHIC] [TIFF OMITTED] TR17AU18.010 [[Page 41269]] [GRAPHIC] [TIFF OMITTED] TR17AU18.011 [[Page 41270]] [GRAPHIC] [TIFF OMITTED] TR17AU18.012 [[Page 41271]] [GRAPHIC] [TIFF OMITTED] TR17AU18.013 [[Page 41272]] [GRAPHIC] [TIFF OMITTED] TR17AU18.014 BILLING CODE 4120-01-C In the FY 2019 IPPS/LTCH PPS proposed rule, we also invited public comments on our proposals related to recalibration of the proposed FY 2019 relative weights and the changes in the relative weights from FY 2018. Comment: Several commenters expressed concern about significant reductions in the relative weights for certain MS-DRGs, typically citing reductions of greater than 20 percent from FY 2018. Some commenters specifically addressed the significant reductions to MS-DRG 215. Commenters stated that the proposed payment rate for MS-DRG 215 is less than the cost of the medical devices used in these procedures, and suggested that the reduced payments resulting from the reduction in the relative weight could limit access to the procedures that map to this MS-DRG. Some commenters suggested that CMS maintain the relative weight for MS-DRG 215 at the FY 2018 level until the claims data reflects the changes in coding advice for [[Page 41273]] procedures that map to this MS-DRG. Other commenters suggested a 1-year policy for FY 2019 to ensure that the 2-year decrease in payment rates for any MS-DRG from FY 2017 does not exceed 20 percent. Yet other commenters suggested a phase-in for MS-DRGs with significant reductions to their weights to give hospitals time to modify their operations to adapt to the new rates. Commenters referenced prior rulemaking in which CMS delayed or transitioned changes impacting payment rates to limit the impact on providers. Response: As we indicated in the FY 2018 IPPS/LTCH final rule (82 FR 38103), we do not believe it is normally appropriate to address relative weight fluctuations that appear to be driven by changes in the underlying data. Nevertheless, after reviewing the comments received and the data used in our ratesetting calculations, we acknowledge an outlier circumstance where the weight for an MS-DRG is seeing a significant reduction of at least 20 percent for each of the 2 years since CMS began using the ICD-10 data in calculating the relative weights. While we would ordinarily consider this weight change to be appropriately driven by the underlying data, given the comments received and the potential for these declines to be related to the ongoing implementation of ICD-10, we are adopting a temporary one-time measure for FY 2019 for an MS-DRG where the FY 2018 relative weight declined by 20 percent from the FY 2017 relative weight and the FY 2019 relative weight would have declined by 20 percent or more from the FY 2018 relative weight. (We note that no FY 2018 weight declined by more than 20 percent from FY 2017 due to our FY 2018 policy.) Specifically, for an MS-DRG meeting this criterion, the FY 2019 relative weight will be set equal to the FY 2018 final relative weight. We believe this policy is consistent with our general authority to assign and update appropriate weighting factors under sections 1886(d)(4)(B) and (C) of the Act. We also believe that it appropriately addresses the situation in which the reduction to the FY 2019 relative weights may still be potentially related to the implementation of ICD-10. We continue to believe that changes in relative weights that are not of this outlier magnitude over the 2 years since we first incorporated the ICD-10 data in our ratesetting are appropriately being driven by the underlying data and not the implementation of ICD-10. There is a significant approximately 10-percentage point outlier gap between this type of reduction and any other reduction that has occurred over the 2-year period. 3. Development of National Average CCRs We developed the national average CCRs as follows: Using the FY 2016 cost report data, we removed CAHs, Indian Health Service hospitals, all-inclusive rate hospitals, and cost reports that represented time periods of less than 1 year (365 days). We included hospitals located in Maryland because we include their charges in our claims database. We then created CCRs for each provider for each cost center (see prior table for line items used in the calculations) and removed any CCRs that were greater than 10 or less than 0.01. We normalized the departmental CCRs by dividing the CCR for each department by the total CCR for the hospital for the purpose of trimming the data. We then took the logs of the normalized cost center CCRs and removed any cost center CCRs where the log of the cost center CCR was greater or less than the mean log plus/minus 3 times the standard deviation for the log of that cost center CCR. Once the cost report data were trimmed, we calculated a Medicare-specific CCR. The Medicare-specific CCR was determined by taking the Medicare charges for each line item from Worksheet D-3 and deriving the Medicare-specific costs by applying the hospital-specific departmental CCRs to the Medicare-specific charges for each line item from Worksheet D-3. Once each hospital's Medicare-specific costs were established, we summed the total Medicare-specific costs and divided by the sum of the total Medicare-specific charges to produce national average, charge-weighted CCRs. Comment: Several commenters noted that the CCRs used in the calculation of the relative weights did not match those calculated using the FY 2016 HCRIS. Response: We appreciate the commenters bringing this issue to our attention. The commenters are correct that there was an error in the calculation of the national average CCRs in the FY 2019 proposed rule, in that we inadvertently used the FY 2015 HCRIS data rather than the FY 2016 HCRIS data. The CCRs used in the calculation of the relative weights in this final rule correctly reflect the described methodology and the FY 2016 HCRIS data. After we multiplied the total charges for each MS-DRG in each of the 19 cost centers by the corresponding national average CCR, we summed the 19 ``costs'' across each MS-DRG to produce a total standardized cost for the MS-DRG. The average standardized cost for each MS-DRG was then computed as the total standardized cost for the MS-DRG divided by the transfer-adjusted case count for the MS-DRG. We calculated the transfer-adjusted discharges for use in the calculation of the Version 36 MS-DRG relative weights using the statutory expansion of the postacute care transfer policy to include discharges to hospice care by a hospice program discussed in section IV.A.2.b. of the preamble of this final rule. For the purposes of calculating the normalization factor, we used the transfer-adjusted discharges with the expanded postacute care transfer policy for Version 35 as well. (When we calculate the normalization factor, we calculate the transfer- adjusted case count for the prior GROUPER version (in this case Version 35) and multiply by the weights of that GROUPER. We then compare that pool to the transfer-adjusted case count using the new GROUPER version.) The average cost for each MS-DRG was then divided by the national average standardized cost per case to determine the relative weight. The FY 2019 cost-based relative weights were then normalized by an adjustment factor of 1.761194774 so that the average case weight after recalibration was equal to the average case weight before recalibration. The normalization adjustment is intended to ensure that recalibration by itself neither increases nor decreases total payments under the IPPS, as required by section 1886(d)(4)(C)(iii) of the Act. The 19 national average CCRs for FY 2019 are as follows: ------------------------------------------------------------------------ Group CCR ------------------------------------------------------------------------ Routine Days................................................... 0.442 Intensive Days................................................. 0.368 Drugs.......................................................... 0.191 Supplies & Equipment........................................... 0.299 Implantable Devices............................................ 0.309 Therapy Services............................................... 0.304 Laboratory..................................................... 0.113 Operating Room................................................. 0.179 Cardiology..................................................... 0.103 Cardiac Catheterization........................................ 0.11 Radiology...................................................... 0.145 MRIs........................................................... 0.074 CT Scans....................................................... 0.035 Emergency Room................................................. 0.159 Blood and Blood Products....................................... 0.296 Other Services................................................. 0.345 Labor & Delivery............................................... 0.382 Inhalation Therapy............................................. 0.156 Anesthesia..................................................... 0.078 ------------------------------------------------------------------------ Since FY 2009, the relative weights have been based on 100 percent cost weights based on our MS-DRG grouping system. When we recalibrated the DRG weights for previous years, we set a [[Page 41274]] threshold of 10 cases as the minimum number of cases required to compute a reasonable weight. We proposed to use that same case threshold in recalibrating the MS-DRG relative weights for FY 2019. Using data from the FY 2017 MedPAR file, there were 7 MS-DRGs that contain fewer than 10 cases. For FY 2019, because we do not have sufficient MedPAR data to set accurate and stable cost relative weights for these low-volume MS-DRGs, we proposed to compute relative weights for the low-volume MS-DRGs by adjusting their final FY 2018 relative weights by the percentage change in the average weight of the cases in other MS-DRGs. The crosswalk table is shown: ------------------------------------------------------------------------ Low-volume MS-DRG MS-DRG title Crosswalk to MS-DRG ------------------------------------------------------------------------ 789...................... Neonates, Died or Final FY 2018 relative Transferred to weight (adjusted by Another Acute Care percent change in Facility. average weight of the cases in other MS- DRGs). 790...................... Extreme Immaturity Final FY 2018 relative or Respiratory weight (adjusted by Distress Syndrome, percent change in Neonate. average weight of the cases in other MS- DRGs). 791...................... Prematurity with Final FY 2018 relative Major Problems. weight (adjusted by percent change in average weight of the cases in other MS- DRGs). 792...................... Prematurity without Final FY 2018 relative Major Problems. weight (adjusted by percent change in average weight of the cases in other MS- DRGs). 793...................... Full-Term Neonate Final FY 2018 relative with Major weight (adjusted by Problems. percent change in average weight of the cases in other MS- DRGs). 794...................... Neonate with Other Final FY 2018 relative Significant weight (adjusted by Problems. percent change in average weight of the cases in other MS DRGs). 795...................... Normal Newborn..... Final FY 2018 relative weight (adjusted by percent change in average weight of the cases in other MS- DRGs). ------------------------------------------------------------------------ After consideration of the comments we received, we are finalizing our proposals, with the modification for recalibrating the relative weights for FY 2019 at the same level as the FY 2018 relative weights for MS-DRGs where the FY 2018 relative weight declined by 20 percent from the FY 2017 relative weight and the FY 2019 relative weight would have declined by 20 percent or more from the FY 2018 relative weight. H. Add-On Payments for New Services and Technologies for FY 2019 1. Background Sections 1886(d)(5)(K) and (L) of the Act establish a process of identifying and ensuring adequate payment for new medical services and technologies (sometimes collectively referred to in this section as ``new technologies'') under the IPPS. Section 1886(d)(5)(K)(vi) of the Act specifies that a medical service or technology will be considered new if it meets criteria established by the Secretary after notice and opportunity for public comment. Section 1886(d)(5)(K)(ii)(I) of the Act specifies that a new medical service or technology may be considered for new technology add-on payment if, based on the estimated costs incurred with respect to discharges involving such service or technology, the DRG prospective payment rate otherwise applicable to such discharges under this subsection is inadequate. We note that, beginning with discharges occurring in FY 2008, CMS transitioned from CMS-DRGs to MS-DRGs. The regulations at 42 CFR 412.87 implement these provisions and specify three criteria for a new medical service or technology to receive the additional payment: (1) The medical service or technology must be new; (2) the medical service or technology must be costly such that the DRG rate otherwise applicable to discharges involving the medical service or technology is determined to be inadequate; and (3) the service or technology must demonstrate a substantial clinical improvement over existing services or technologies. Below we highlight some of the major statutory and regulatory provisions relevant to the new technology add-on payment criteria, as well as other information. For a complete discussion on the new technology add-on payment criteria, we refer readers to the FY 2012 IPPS/LTCH PPS final rule (76 FR 51572 through 51574). Under the first criterion, as reflected in Sec. 412.87(b)(2), a specific medical service or technology will be considered ``new'' for purposes of new medical service or technology add-on payments until such time as Medicare data are available to fully reflect the cost of the technology in the MS-DRG weights through recalibration. We note that we do not consider a service or technology to be new if it is substantially similar to one or more existing technologies. That is, even if a technology receives a new FDA approval or clearance, it may not necessarily be considered ``new'' for purposes of new technology add-on payments if it is ``substantially similar'' to a technology that was approved or cleared by FDA and has been on the market for more than 2 to 3 years. In the FY 2010 IPPS/RY 2010 LTCH PPS final rule (74 FR 43813 through 43814), we established criteria for evaluating whether a new technology is substantially similar to an existing technology, specifically: (1) Whether a product uses the same or a similar mechanism of action to achieve a therapeutic outcome; (2) whether a product is assigned to the same or a different MS-DRG; and (3) whether the new use of the technology involves the treatment of the same or similar type of disease and the same or similar patient population. If a technology meets all three of these criteria, it would be considered substantially similar to an existing technology and would not be considered ``new'' for purposes of new technology add-on payments. For a detailed discussion of the criteria for substantial similarity, we refer readers to the FY 2006 IPPS final rule (70 FR 47351 through 47352), and the FY 2010 IPPS/LTCH PPS final rule (74 FR 43813 through 43814). Under the second criterion, Sec. 412.87(b)(3) further provides that, to be eligible for the add-on payment for new medical services or technologies, the MS-DRG prospective payment rate otherwise applicable to discharges involving the new medical service or technology must be assessed for adequacy. Under the cost criterion, consistent with the formula specified in section 1886(d)(5)(K)(ii)(I) of the Act, to assess the adequacy of payment for a new technology paid under the applicable MS-DRG prospective payment rate, we evaluate whether the charges for cases involving the new technology exceed certain threshold amounts. Table 10 that was released with the FY 2018 IPPS/LTCH PPS final rule contains the final thresholds that we used to evaluate applications for new medical service or technology add- [[Page 41275]] on payments for FY 2019. We refer readers to the CMS website at: https://www.cms.gov/Medicare/Medicare-Fee-for-Service-Payment/AcuteInpatientPPS/FY2018-IPPS-Final-Rule-Home-Page-Items/FY2018-IPPS-Final-Rule-Tables.html to download and view Table 10. As previously stated, Table 10 that is released with each proposed and final rule contains the thresholds that we use to evaluate applications for new medical service and technology add-on payments for the fiscal year that follows the fiscal year that is otherwise the subject of the rulemaking. For example, the thresholds in Table 10 released with the FY 2018 IPPS/LTCH PPS final rule are applicable to FY 2019 new technology applications. In the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20276), we proposed, beginning with the thresholds for FY 2020 and future years, to provide the thresholds that we previously included in Table 10 as one of our data files posted via the internet on the CMS website at: http://www.cms.hhs.gov/Medicare/Medicare-Fee-for-Service-Payment/AcuteInpatientPPS/index.html, which is the same URL where the impact data files associated with the rulemaking for the applicable fiscal year are posted. We stated that we believed this proposed change in the presentation of this information, specifically in the data files rather than in a Table 10, will clarify for the public that the listed thresholds will be used for new technology add- on payment applications for the next fiscal year (in this case, for FY 2020) rather than for the fiscal year that is otherwise the subject of the rulemaking (in this case, for FY 2019), while continuing to furnish the same information on the new technology add-on payment thresholds for applications for the next fiscal year as has been provided in previous fiscal years. Accordingly, we would no longer include Table 10 as one of our IPPS tables, but would instead include the thresholds applicable to the next fiscal year (beginning with FY 2020) in the data files associated with the prior fiscal year (in this case, FY 2019). We did not receive any public comments on this proposal. Therefore, we are finalizing the proposal, without modification, and presenting the MS-DRG threshold amounts (previously included in Table 10 of the annual IPPS/LTCH PPS proposed and final rules) that will be used in evaluating new technology add-on payment applications for FY 2020 in a data file that is available, along with the other data files associated with this FY 2019 IPPS/LTCH PPS final rule, on the CMS website at: http://www.cms.hhs.gov/Medicare/Medicare-Fee-for-Service-Payment/AcuteInpatientPPS/index.html. In the September 7, 2001 final rule that established the new technology add-on payment regulations (66 FR 46917), we discussed the issue of whether the Health Insurance Portability and Accountability Act (HIPAA) Privacy Rule at 45 CFR parts 160 and 164 applies to claims information that providers submit with applications for new medical service or technology add-on payments. We refer readers to the FY 2012 IPPS/LTCH PPS final rule (76 FR 51573) for complete information on this issue. Under the third criterion, Sec. 412.87(b)(1) of our existing regulations provides that a new technology is an appropriate candidate for an additional payment when it represents an advance that substantially improves, relative to technologies previously available, the diagnosis or treatment of Medicare beneficiaries. For example, a new technology represents a substantial clinical improvement when it reduces mortality, decreases the number of hospitalizations or physician visits, or reduces recovery time compared to the technologies previously available. (We refer readers to the September 7, 2001 final rule for a more detailed discussion of this criterion (66 FR 46902).) The new medical service or technology add-on payment policy under the IPPS provides additional payments for cases with relatively high costs involving eligible new medical services or technologies, while preserving some of the incentives inherent under an average-based prospective payment system. The payment mechanism is based on the cost to hospitals for the new medical service or technology. Under Sec. 412.88, if the costs of the discharge (determined by applying cost-to- charge ratios (CCRs) as described in Sec. 412.84(h)) exceed the full DRG payment (including payments for IME and DSH, but excluding outlier payments), Medicare will make an add-on payment equal to the lesser of: (1) 50 percent of the estimated costs of the new technology or medical service (if the estimated costs for the case including the new technology or medical service exceed Medicare's payment); or (2) 50 percent of the difference between the full DRG payment and the hospital's estimated cost for the case. Unless the discharge qualifies for an outlier payment, the additional Medicare payment is limited to the full MS-DRG payment plus 50 percent of the estimated costs of the new technology or medical service. Section 503(d)(2) of Public Law 108-173 provides that there shall be no reduction or adjustment in aggregate payments under the IPPS due to add-on payments for new medical services and technologies. Therefore, in accordance with section 503(d)(2) of Public Law 108-173, add-on payments for new medical services or technologies for FY 2005 and later years have not been subjected to budget neutrality. In the FY 2009 IPPS final rule (73 FR 48561 through 48563), we modified our regulations at Sec. 412.87 to codify our longstanding practice of how CMS evaluates the eligibility criteria for new medical service or technology add-on payment applications. That is, we first determine whether a medical service or technology meets the newness criterion, and only if so, do we then make a determination as to whether the technology meets the cost threshold and represents a substantial clinical improvement over existing medical services or technologies. We amended Sec. 412.87(c) to specify that all applicants for new technology add-on payments must have FDA approval or clearance for their new medical service or technology by July 1 of the year prior to the beginning of the fiscal year that the application is being considered. The Council on Technology and Innovation (CTI) at CMS oversees the agency's cross-cutting priority on coordinating coverage, coding and payment processes for Medicare with respect to new technologies and procedures, including new drug therapies, as well as promoting the exchange of information on new technologies and medical services between CMS and other entities. The CTI, composed of senior CMS staff and clinicians, was established under section 942(a) of Public Law 108- 173. The Council is co-chaired by the Director of the Center for Clinical Standards and Quality (CCSQ) and the Director of the Center for Medicare (CM), who is also designated as the CTI's Executive Coordinator. The specific processes for coverage, coding, and payment are implemented by CM, CCSQ, and the local Medicare Administrative Contractors (MACs) (in the case of local coverage and payment decisions). The CTI supplements, rather than replaces, these processes by working to assure that all of these activities reflect the agency- wide priority to promote high-quality, innovative care. At the same time, the CTI also works to streamline, accelerate, and improve coordination of these processes to ensure that they remain up to date as new issues arise. To achieve its goals, the CTI works to streamline [[Page 41276]] and create a more transparent coding and payment process, improve the quality of medical decisions, and speed patient access to effective new treatments. It is also dedicated to supporting better decisions by patients and doctors in using Medicare-covered services through the promotion of better evidence development, which is critical for improving the quality of care for Medicare beneficiaries. To improve the understanding of CMS' processes for coverage, coding, and payment and how to access them, the CTI has developed an ``Innovator's Guide'' to these processes. The intent is to consolidate this information, much of which is already available in a variety of CMS documents and in various places on the CMS website, in a user friendly format. This guide was published in 2010 and is available on the CMS website at: https://www.cms.gov/Medicare/Coverage/CouncilonTechInnov/Downloads/Innovators-Guide-Master-7-23-15.pdf. As we indicated in the FY 2009 IPPS final rule (73 FR 48554), we invite any product developers or manufacturers of new medical services or technologies to contact the agency early in the process of product development if they have questions or concerns about the evidence that would be needed later in the development process for the agency's coverage decisions for Medicare. The CTI aims to provide useful information on its activities and initiatives to stakeholders, including Medicare beneficiaries, advocates, medical product manufacturers, providers, and health policy experts. Stakeholders with further questions about Medicare's coverage, coding, and payment processes, or who want further guidance about how they can navigate these processes, can contact the CTI at [email protected]. In the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20277), we noted that applicants for add-on payments for new medical services or technologies for FY 2020 must submit a formal request, including a full description of the clinical applications of the medical service or technology and the results of any clinical evaluations demonstrating that the new medical service or technology represents a substantial clinical improvement, along with a significant sample of data to demonstrate that the medical service or technology meets the high-cost threshold. Complete application information, along with final deadlines for submitting a full application, will be posted as it becomes available on the CMS website at: https://www.cms.gov/Medicare/Medicare-Fee-for-Service-Payment/AcuteInpatientPPS/newtech.html. To allow interested parties to identify the new medical services or technologies under review before the publication of the proposed rule for FY 2020, the CMS website also will post the tracking forms completed by each applicant. We note that the burden associated with this information collection requirement is the time and effort required to collect and submit the data in the formal request for add-on payments for new medical services and technologies to CMS. The aforementioned burden is subject to the PRA; it is currently approved under OMB control number 0938-1347, which expires on December 31, 2020. 2. Public Input Before Publication of a Notice of Proposed Rulemaking on Add-On Payments Section 1886(d)(5)(K)(viii) of the Act, as amended by section 503(b)(2) of Public Law 108-173, provides for a mechanism for public input before publication of a notice of proposed rulemaking regarding whether a medical service or technology represents a substantial clinical improvement or advancement. The process for evaluating new medical service and technology applications requires the Secretary to-- Provide, before publication of a proposed rule, for public input regarding whether a new service or technology represents an advance in medical technology that substantially improves the diagnosis or treatment of Medicare beneficiaries; Make public and periodically update a list of the services and technologies for which applications for add-on payments are pending; Accept comments, recommendations, and data from the public regarding whether a service or technology represents a substantial clinical improvement; and Provide, before publication of a proposed rule, for a meeting at which organizations representing hospitals, physicians, manufacturers, and any other interested party may present comments, recommendations, and data regarding whether a new medical service or technology represents a substantial clinical improvement to the clinical staff of CMS. In order to provide an opportunity for public input regarding add- on payments for new medical services and technologies for FY 2019 prior to publication of the FY 2019 IPPS/LTCH PPS proposed rule, we published a notice in the Federal Register on December 4, 2017 (82 FR 57275), and held a town hall meeting at the CMS Headquarters Office in Baltimore, MD, on February 13, 2018. In the announcement notice for the meeting, we stated that the opinions and presentations provided during the meeting would assist us in our evaluations of applications by allowing public discussion of the substantial clinical improvement criterion for each of the FY 2019 new medical service and technology add-on payment applications before the publication of the FY 2019 IPPS/LTCH PPS proposed rule. As stated in the proposed rule, approximately 150 individuals registered to attend the town hall meeting in person, while additional individuals listened over an open telephone line. We also live-streamed the town hall meeting and posted the town hall on the CMS YouTube web page at: https://www.youtube.com/watch?v=9niqfxXe4oA&t=217s. We considered each applicant's presentation made at the town hall meeting, as well as written comments submitted on the applications that were received by the due date of February 23, 2018, in our evaluation of the new technology add-on payment applications for FY 2019 in the FY 2019 IPPS/LTCH PPS proposed rule. In response to the published notice and the February 13, 2018 New Technology Town Hall meeting, we received written comments regarding the applications for FY 2019 new technology add-on payments. (We refer readers to the FY 2019 IPPS/LTCH PPS proposed rule for summaries of the comments received in response to the published notice and the New Technology Town Hall meeting and our responses (83 FR 20278 through 20280).) We also noted in the proposed rule that we do not summarize comments that are unrelated to the ``substantial clinical improvement'' criterion. As explained earlier and in the Federal Register notice announcing the New Technology Town Hall meeting (82 FR 57275 through 57277), the purpose of the meeting was specifically to discuss the substantial clinical improvement criterion in regard to pending new technology add-on payment applications for FY 2019. Therefore, we did not summarize those written comments in the proposed rule. In section II.H.5. of the preamble of the FY 2019 IPPS/LTCH PPS proposed rule, we summarized comments regarding individual applications, or, if applicable, indicated that there were no comments received in response to the New Technology Town Hall meeting [[Page 41277]] notice, at the end of each discussion of the individual applications. Public commenters stated opinions and made suggestions relating to the mapping of new technologies to the appropriate MS-DRG, deeming a new technology a substantial clinical improvement if it receives HDE approval from the FDA, and the use of external data in determining the cost threshold that CMS considers to be outside of the scope of the proposed rule. Because we did not request public comments nor propose to make any changes to any of the issues above, we are not summarizing these public comments, nor responding to them in this final rule. As noted below in section II.H.5.a. of the preamble of this final rule, we refer readers to section II.F.2.d. of the preamble of this final rule for a summary of and our responses to the public comments we received in response to our solicitation regarding the most appropriate mechanism to provide payment to hospitals for new technologies, such as CAR T-cell therapy drugs, including through the use of new technology add-on payments (82 FR 20294), as well as a summary of the public comments we received in response to the solicitation for public comment on our concerns with the payment alternatives that we considered for CAR T-cell therapy drugs and therapies and our responses to those comments (83 FR 20190). 3. ICD-10-PCS Section ``X'' Codes for Certain New Medical Services and Technologies As discussed in the FY 2016 IPPS/LTCH final rule (80 FR 49434), the ICD-10-PCS includes a new section containing the new Section ``X'' codes, which began being used with discharges occurring on or after October 1, 2015. Decisions regarding changes to ICD-10-PCS Section ``X'' codes will be handled in the same manner as the decisions for all of the other ICD-10-PCS code changes. That is, proposals to create, delete, or revise Section ``X'' codes under the ICD-10-PCS structure will be referred to the ICD-10 Coordination and Maintenance Committee. In addition, several of the new medical services and technologies that have been, or may be, approved for new technology add-on payments may now, and in the future, be assigned a Section ``X'' code within the structure of the ICD-10-PCS. We posted ICD-10-PCS Guidelines on the CMS website at: http://www.cms.gov/Medicare/Coding/ICD10/2016-ICD-10-PCS-and-GEMs.html, including guidelines for ICD-10-PCS Section ``X'' codes. We encourage providers to view the material provided on ICD-10-PCS Section ``X'' codes. 4. FY 2019 Status of Technologies Approved for FY 2018 Add-On Payments a. Defitelio[supreg] (Defibrotide) Jazz Pharmaceuticals submitted an application for new technology add-on payments for FY 2017 for Defitelio[supreg] (defibrotide), a treatment for patients diagnosed with hepatic veno-occlusive disease (VOD) with evidence of multiorgan dysfunction. VOD, also known as sinusoidal obstruction syndrome (SOS), is a potentially life- threatening complication of hematopoietic stem cell transplantation (HSCT), with an incidence rate of 8 percent to 15 percent. Diagnoses of VOD range in severity from what has been classically defined as a disease limited to the liver (mild) and reversible, to a severe syndrome associated with multi-organ dysfunction or failure and death. Patients treated with HSCT who develop VOD with multi-organ failure face an immediate risk of death, with a mortality rate of more than 80 percent when only supportive care is used. The applicant asserted that Defitelio[supreg] improves the survival rate of patients diagnosed with VOD with multi-organ failure by 23 percent. Defitelio[supreg] received Orphan Drug Designation for the treatment of VOD in 2003 and for the prevention of VOD in 2007. It has been available to patients as an investigational drug through an expanded access program since 2006. The applicant's New Drug Application (NDA) for Defitelio[supreg] received FDA approval on March 30, 2016. The applicant confirmed that Defitelio[supreg] was not available on the U.S. market as of the FDA NDA approval date of March 30, 2016. According to the applicant, commercial packaging could not be completed until the label for Defitelio[supreg] was finalized with FDA approval, and that commercial shipments of Defitelio[supreg] to hospitals and treatment centers began on April 4, 2016. Therefore, we agreed that, based on this information, the newness period for Defitelio[supreg] begins on April 4, 2016, the date of its first commercial availability. The applicant received approval to use unique ICD-10-PCS procedure codes to describe the use of Defitelio[supreg], with an effective date of October 1, 2016. The approved ICD-10PCS procedure codes are: XW03392 (Introduction of defibrotide sodium anticoagulant into peripheral vein, percutaneous approach); and XW04392 (Introduction of defibrotide sodium anticoagulant into central vein, percutaneous approach). After evaluation of the newness, costs, and substantial clinical improvement criteria for new technology add-on payments for Defitelio[supreg] and consideration of the public comments we received in response to the FY 2017 IPPS/LTCH PPS proposed rule, we approved Defitelio[supreg] for new technology add-on payments for FY 2017 (81 FR 56906). With the new technology add-on payment application, the applicant estimated that the average Medicare beneficiary would require a dosage of 25 mg/kg/day for a minimum of 21 days of treatment. The recommended dose is 6.25 mg/kg given as a 2-hour intravenous infusion every 6 hours. Dosing should be based on a patient's baseline body weight, which is assumed to be 70 kg for an average adult patient. All vials contain 200 mg at a cost of $825 per vial. Therefore, we determined that cases involving the use of the Defitelio[supreg] technology would incur an average cost per case of $151,800 (70 kg adult x 25 mg/kg/day x 21 days = 36,750 mg per patient/200 mg vial = 184 vials per patient x $825 per vial = $151,800). Under Sec. 412.88(a)(2), we limit new technology add-on payments to the lesser of 50 percent of the average cost of the technology or 50 percent of the costs in excess of the MS-DRG payment for the case. As a result, the maximum new technology add-on payment amount for a case involving the use of Defitelio[supreg] is $75,900. Our policy is that a medical service or technology may continue to be considered ``new'' for purposes of new technology add-on payments within 2 or 3 years after the point at which data begin to become available reflecting the inpatient hospital code assigned to the new service or technology. Our practice has been to begin and end new technology add-on payments on the basis of a fiscal year, and we have generally followed a guideline that uses a 6-month window before and after the start of the fiscal year to determine whether to extend the new technology add-on payment for an additional fiscal year. In general, we extend new technology add-on payments for an additional year only if the 3-year anniversary date of the product's entry onto the U.S. market occurs in the latter half of the fiscal year (70 FR 47362). With regard to the newness criterion for Defitelio[supreg], we considered the beginning of the newness period to commence on the first day Defitelio[supreg] was commercially available (April 4, 2016). Because the 3-year anniversary date of the entry of the Defitelio[supreg] onto the U.S. market (April 4, 2019) will [[Page 41278]] occur in the latter half of FY 2019, in the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20280 through 20281), we proposed to continue new technology add-on payments for this technology for FY 2019. We proposed that the maximum payment for a case involving Defitelio[supreg] would remain at $75,900 for FY 2019. We invited public comments on our proposal to continue new technology add-on payments for Defitelio[supreg] for FY 2019. Comment: A few commenters agreed with CMS' proposal to continue new technology add-on payments for Defitelio[supreg] for FY 2019. In addition, the applicant provided updated cost information that indicated, as of April 4, 2018, the current Wholesale Acquisition Cost (WAC) for Defitelio[supreg] is $875.24 per vial, which changes the average cost per case from $151,800 to $161,000 (70 kg adult x 25 mg/ kg/day x 21 days = 36,750 mg per patient/200 mg vial = 184 vials per patient x $875 per vial = $161,000). As such, the applicant requested that CMS revise the maximum new technology add-on payment for Defitelio[supreg] for FY 2019 to $80,500, or increase the maximum new technology add-on payment for cases involving the use of Defitelio[supreg] to 50 percent of the revised WAC of the technology per case. Response: We appreciate the commenters' support and the updated cost information submitted by the applicant. After consideration of the public comments we received, we are finalizing our proposal, with modification, to continue new technology add-on payments for Defitelio[supreg] for FY 2019. Based on the applicant's updated cost information, the maximum new technology add-on payment for a case involving the use of Defitelio[supreg] is $80,500 for FY 2019. b. EDWARDS INTUITY Elite\TM\ Valve System (INTUITY) and LivaNova Perceval Valve (Perceval) Two manufacturers, Edwards Lifesciences and LivaNova, submitted applications for new technology add-on payments for FY 2018 for the INTUITY Elite\TM\ Valve System (INTUITY) and the Perceval Valve (Perceval), respectively. Both of these technologies are prosthetic aortic valves inserted using surgical aortic valve replacement (AVR). The applicant for the INTUITY valve stated that it has a unique design, which utilizes features that were not previously included in conventional aortic valves. The deployment mechanism allows for rapid deployment. The expandable frame can reshape the native valve's orifice, creating a larger and more efficiently shaped effective orifice area. In addition, the expandable skirt allows for structural differentiation upon fixation of the valve requiring 3 permanent, guiding sutures rather than the 12 to 18 permanent sutures used to fasten standard prosthetic aortic valves. The applicant for the Perceval valve described the Perceval valve as including: (a) No permanent sutures; (b) a dedicated delivery system that increases the surgeon's visibility; (c) an enabler of a minimally invasive approach; (d) a capability to promote complexity reduction and reproducibility of the procedure; and (e) a unique device assembly and delivery system. Aortic valvular disease is relatively common, primarily manifested by aortic stenosis. Most aortic stenosis is due to calcification of the valve, either on a normal tri-leaflet valve or on a congenitally bicuspid valve. The resistance to outflow of blood is progressive over time, and as the size of the aortic orifice narrows, the heart must generate increasingly elevated pressures to maintain blood flow. Symptoms such as angina, heart failure, and syncope eventually develop, and portend a very serious prognosis. There is no effective medical therapy for aortic stenosis, so the diseased valve must be replaced or, less commonly, repaired. According to both applicants, the INTUITY valve and the Perceval valve are the first sutureless, rapid deployment aortic valves that can be used for the treatment of patients who are candidates for surgical AVR. Because potential cases representing patients who are eligible for treatment using the INTUITY and the Perceval aortic valve devices would group to the same MS-DRGs, and we believe that these devices are intended to treat the same or similar disease in the same or similar patient population, and are purposed to achieve the same therapeutic outcome using the same or similar mechanism of action, we determined these two devices are substantially similar to each other and that it was appropriate to evaluate both technologies as one application for new technology add-on payments under the IPPS. With respect to the newness criterion, the INTUITY valve received FDA approval on August 12, 2016, and was commercially available on the U.S. market on August 19, 2016. The Perceval valve received FDA approval on January 8, 2016, and was commercially available on the U.S. market on February 29, 2016. In accordance with our policy, we stated in the FY 2018 IPPS/LTCH PPS final rule (82 FR 38120) that we believe it is appropriate to use the earliest market availability date submitted as the beginning of the newness period. Accordingly, for both devices, we stated that the beginning of the newness period is February 29, 2016, when the Perceval valve became commercially available. The ICD-10-PCS code approved to identify procedures involving the use of both devices when surgically implanted is ICD-10-PCS code X2RF032 (Replacement of aortic valve using zooplastic tissue, rapid deployment technique, open approach, new technology group 2). After evaluation of the newness, costs, and substantial clinical improvement criteria for new technology add-on payments for the INTUITY and Perceval valves and consideration of the public comments we received in response to the FY 2018 IPPS/LTCH PPS proposed rule, we approved the INTUITY and Perceval valves for new technology add-on payments for FY 2018 (82 FR 38125). We stated that we believed that the use of a weighted-average of the cost of the standard valves based on the projected number of cases involving each technology to determine the maximum new technology add-on payment was most appropriate. To compute the weighted-cost average, we summed the total number of projected cases for each of the applicants, which equaled 2,429 cases (1,750 plus 679). We then divided the number of projected cases for each of the applicants by the total number of cases, which resulted in the following case-weighted percentages: 72 percent for the INTUITY and 28 percent for the Perceval valve. We then multiplied the cost per case for the manufacturer specific valve by the case-weighted percentage (0.72 * $12,500 = $9,005.76 for INTUITY and 0.28 * $11,500 = $3,214.70 for the Perceval valve). This resulted in a case-weighted average cost of $12,220.46 for the valves. Under Sec. 412.88(a)(2), we limit new technology add-on payments to the lesser of 50 percent of the average cost of the device or 50 percent of the costs in excess of the MS-DRG payment for the case. As a result, the maximum new technology add-on payment for a case involving the INTUITY or Perceval valves is $6,110.23 for FY 2018. With regard to the newness criterion for the INTUITY and Perceval valves, we considered the newness period for the INTUITY and Perceval valves to begin February 29, 2016. As discussed previously in this section, in general, we extend new technology add-on payments for an additional year only if the 3-year anniversary date of the product's entry onto the U.S. market [[Page 41279]] occurs in the latter half of the upcoming fiscal year. Because the 3- year anniversary date of the entry of the technology onto the U.S. market (February 29, 2019) will occur in the first half of FY 2019, in the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20281), we proposed to discontinue new technology add-on payments for the INTUITY and Perceval valves for FY 2019. We invited public comments on our proposal to discontinue new technology add-on payments for the INTUITY and Perceval valves. Comment: Some commenters supported CMS' proposal to discontinue new technology add-on payments for the INTUITY and Perceval valves and stated that the consideration of these two applications together demonstrated CMS' commitment to efficiency and optimization of the new technology add-on payment application process. Most commenters agreed that it is appropriate for the newness period to be based on the earliest anniversary date of the product's entry onto the U.S. market, given that the two technologies were evaluated and approved as one application. Other commenters disagreed with CMS' proposal to discontinue new technology add-on payments for the INTUITY and Perceval valves for reasons including the following: (1) There is no precedent for CMS to determine the 3-year anniversary date of a product's entry onto the U.S. market for two technologies that have been jointly awarded new technology add-on payments with different market availability dates; (2) it is inappropriate to choose the earliest market availability date for this class of technologies because it does not acknowledge the disparate newness periods for the two applicants; and (3) Medicare claims data and MS-DRG payment rates do not adequately reflect the additional costs of these technologies. Instead, some of these commenters suggested that the mid-point of the two commercial market availability dates for the Perceval and INTUITY valves be used as the beginning of the newness period, which would be May 25, 2016. These commenters believed that, by using the May 25, 2016 mid-point commercial market availability date, the newness period would conclude on May 25, 2019, which occurs in the second half of the fiscal year and, therefore, would allow new technology add-on payments for the Perceval and INTUITY valves to continue through FY 2019. Another commenter also disagreed with CMS' proposal to discontinue new technology add-on payments for the Perceval and INTUITY valves because the commenter believed that the commercial market availability date of February 29, 2016, is an inappropriate beginning for the newness period for the Perceval valve due to the thorough training and education process that was implemented by LivaNova, which impacted the market availability of the Perceval valve prior to April 1, 2016, and noted there were fewer than 30 Medicare patients who received implants involving the use of the Perceval valve prior to April 1, 2016. Response: We appreciate the commenters' input. With regard to the beginning of the technology's newness period, as discussed in the FY 2005 IPPS final rule (69 FR 49003), the timeframe that a new technology can be eligible to receive new technology add-on payments begins when data begin to become available. Therefore, the precedent the commenter mentions regarding two technologies that have been jointly awarded new technology add-on payments with different commercial market availability dates is not relevant. Section 412.87(b)(2) states that a medical service or technology may be considered ``new'' within 2 or 3 years after the point at which data begin to become available reflecting the inpatient hospital code assigned to the new service or technology (depending on when a new code is assigned and data on the new service or technology become available for DRG recalibration). Section 412.87(b)(2) also specifies that after CMS has recalibrated the DRGs, based on available data, to reflect the costs of an otherwise new medical service or technology, the medical service or technology will no longer be considered ``new'' under the criterion of the section. Additionally, as stated above, we have determined that the Perceval and INTUITY valves are substantially similar to each other and, therefore, we used the earliest date when data became available for the technology to determine the beginning of the newness period. Therefore, the newness period began February 29, 2016. In addition, we do not believe that case volume is a relevant consideration for making the determination as to whether a product is ``new.'' Consistent with the statute and our implementing regulations, a technology is no longer considered as ``new'' once it is more than 2 to 3 years old, irrespective of how frequently the medical service or technology has been used in the Medicare population (70 FR 47349). As such, in this case, because the Perceval and INTUITY valves have been available on the U.S. market for more than 2 to 3 years, we consider the costs to have been included in the MS-DRG relative weights regardless of whether the technologies' use in the Medicare population has been frequent or infrequent. Based on all of the reasons stated above, the Perceval and INTUITY valves are no longer considered ``new'' for purposes of new technology add-on payments for FY 2019. Therefore, after consideration of the public comments we received, we are finalizing our proposal to discontinue new technology add-on payments for the Perceval and INTUITY valves for FY 2019. c. GORE[supreg] EXCLUDER[supreg] Iliac Branch Endoprosthesis (Gore IBE Device) W. L. Gore and Associates, Inc. submitted an application for new technology add-on payments for the GORE[supreg] EXCLUDER[supreg] Iliac Branch Endoprosthesis (GORE IBE device) for FY 2017. The device consists of two components: The Iliac Branch Component (IBC) and the Internal Iliac Component (IIC). The applicant indicated that each endoprosthesis is pre-mounted on a customized delivery and deployment system allowing for controlled endovascular delivery via bilateral femoral access. According to the applicant, the device is designed to be used in conjunction with the GORE[supreg] EXCLUDER[supreg] AAA Endoprosthesis for the treatment of patients requiring repair of common iliac or aortoiliac aneurysms. When deployed, the GORE IBE device excludes the common iliac aneurysm from systemic blood flow, while preserving blood flow in the external and internal iliac arteries. With regard to the newness criterion, the applicant received FDA pre-market approval of the GORE IBE device on February 29, 2016. The following procedure codes describe the use of this technology: 04VC0EZ (Restriction of right common iliac artery with branched or fenestrated intraluminal device, one or two arteries, open approach); 04VC3EZ (Restriction of right common iliac artery with branched or fenestrated intraluminal device, one or two arteries, percutaneous approach); 04VC4EZ (Restriction of right common iliac artery with branched or fenestrated intraluminal device, one or two arteries, percutaneous approach); 04VD0EZ (Restriction of left common iliac artery with branched or fenestrated intraluminal device, one or two arteries, open approach); 04VD3EZ (Restriction of left common iliac artery with branched or fenestrated intraluminal device, one or two arteries, percutaneous approach); 04VD4EZ (Restriction of left common iliac artery [[Page 41280]] with branched or fenestrated intraluminal device, one or two arteries, percutaneous endoscopic approach). After evaluation of the newness, costs, and substantial clinical improvement criteria for new technology add-on payments for the GORE IBE device and consideration of the public comments we received in response to the FY 2017 IPPS/LTCH PPS proposed rule, we approved the GORE IBE device for new technology add-on payments for FY 2017 (81 FR 56909). With the new technology add-on payment application, the applicant indicated that the total operating cost of the GORE IBE device is $10,500. Under Sec. 412.88(a)(2), we limit new technology add-on payments to the lesser of 50 percent of the average cost of the device, or 50 percent of the costs in excess of the MS-DRG payment for the case. As a result, the maximum new technology add-on payment for a case involving the GORE IBE device is $5,250. With regard to the newness criterion for the GORE IBE device, we considered the beginning of the newness period to commence when the GORE IBE device received FDA approval on February 29, 2016. As discussed previously in this section, in general, we extend new technology add-on payments for an additional year only if the 3-year anniversary date of the product's entry onto the U.S. market occurs in the latter half of the upcoming fiscal year. Because the 3-year anniversary date of the entry of the GORE IBE device onto the U.S. market (February 28, 2019) will occur in the first half of FY 2019, in the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20282), we proposed to discontinue new technology add-on payments for this technology for FY 2019. We invited public comments on our proposal to discontinue new technology add-on payments for the GORE IBE device. Comment: The applicant (manufacturer) disagreed with CMS' proposal to discontinue new technology add-on payments for the GORE IBE device, and recommended that CMS continue new technology add-on payments for an additional year until sufficient claims data are available to reflect the cost of the technology. The applicant indicated that the FDA approval date is the date that the manufacturer may begin commercialization and actual manufacturing and marketing takes several months. As such, the applicant believed that it would be more appropriate to use the date of first sale or the date of the first procedure as the beginning of the newness period because it would more appropriately align with the point at which claims and costs data would begin to become available. With regard to the GORE IBE device, the applicant noted that there was a deletion of ICD-10-PCS procedure codes in FY 2018 used for the coding of procedures identifying the GORE IBE implant, which created confusion for hospital billing departments that were reporting these codes. As a result, the applicant believed that the GORE IBE implant procedures may have been under-reported and the claims data has not captured the utilization and cost data for these implant procedures. Additionally, the applicant stated that MACs, as a general practice, do not include Category III CPT codes in their internal processes and, specifically, do not include 0254T for the identification of the GORE IBE procedure. The applicant believed that this lack of alignment between the new technology add-on payment policy and the MACs' treatment of Category III CPT codes for the identification of GORE IBE procedures likely contributed to the severe under-reporting of procedures involving the GORE IBE implant. Therefore, the applicant recommended that CMS maintain consistent ICD-10 coding practices, encourage the MACs to include procedures involving devices for which new technology add-on payments are effective in their internal processes, and extend new technology add-on payments for the GORE IBE technology through FY 2019 to allow assessment of sufficient claims data that reflect the costs of the GORE IBE device. Response: We appreciate the applicant's input. As stated above, while CMS may consider a documented delay in a technology's availability on the U.S. market in determining when the newness period begins, its policy for determining whether to extend new technology add-on payments for an additional year generally applies regardless of the volume of claims for the technology after the beginning of the newness period. Similar to our discussion earlier and in the FY 2006 IPPS final rule (70 FR 47349), we do not believe that case volume is a relevant consideration for making the determination as to whether a product is considered ``new'' for purposes of new technology add-on payments. Consistent with the statute and our implementing regulations, a technology is no longer considered ``new'' once it is more than 2 to 3 years old, and the costs of the procedures are considered to be included in the relative weights irrespective of how frequently the technology has been used in the Medicare population. Additionally, since the technology is on the market coding changes or local coverage determinations typically do not delay the beginning of the newness period. Therefore, in this case, because the GORE IBE device has been available on the U.S. market for more than 2 to 3 years, we consider claims and costs data to be available for DRG recalibration of the relative weights, and the costs of the technology to have been included in the MS-DRG relative weights regardless of whether the technology's use in the Medicare population has been frequent or infrequent. Based on the reasons stated above, the GORE IBE device is no longer considered ``new'' for purposes of new technology add-on payments for FY 2019. Therefore, after consideration of the public comments we received, we are finalizing our proposal to discontinue new technology add-on payments for the GORE IBE device for FY 2019. d. PRAXBIND (Idarucizumab) Boehringer Ingelheim Pharmaceuticals, Inc. submitted an application for new technology add-on payments for FY 2017 for idarucizumab (also known as PRAXBIND), a product developed as an antidote to reverse the effects of PRADAXA (dabigatran), which is also manufactured by Boehringer Ingelheim Pharmaceuticals, Inc. Dabigatran is an oral direct thrombin inhibitor currently indicated: (1) To reduce the risk of stroke and systemic embolism in patients who have been diagnosed with nonvalvular atrial fibrillation (NVAF); (2) for the treatment of deep venous thrombosis (DVT) and pulmonary embolism (PE) in patients who have been administered a parenteral anticoagulant for 5 to 10 days; (3) to reduce the risk of recurrence of DVT and PE in patients who have been previously treated; and (4) for the prophylaxis of DVT and PE in patients who have undergone hip replacement surgery. Currently, unlike the anticoagulant warfarin, there is no specific way to reverse the anticoagulant effect of dabigatran in the event of a major bleeding episode. Idarucizumab is a humanized fragment antigen binding (Fab) molecule, which specifically binds to dabigatran to deactivate the anticoagulant effect, thereby allowing thrombin to act in blood clot formation. The applicant stated that idarucizumab represents a new pharmacologic approach to neutralizing the specific anticoagulant effect of dabigatran in emergency situations. PRAXBIND was approved by the FDA on October 16, 2015. PRAXBIND is indicated for the use in the treatment of [[Page 41281]] patients who have been administered PRADAXA when reversal of the anticoagulant effects of dabigatran is needed for emergency surgery or urgent medical procedures or in life-threatening or uncontrolled bleeding. The applicant was granted approval to use unique ICD-10-PCS procedure codes that became effective October 1, 2016, to describe the use of this technology. The approved ICD-10-PCS procedure codes are: XW03331 (Introduction of idarucizumab, dabigatran reversal agent into peripheral vein, percutaneous approach, new technology group 1); and XW04331 (Introduction of idarucizumab, dabigatran reversal agent into central vein, percutaneous approach, new technology group 1). After evaluation of the newness, costs, and substantial clinical improvement criteria for new technology add-on payments for idarucizumab and consideration of the public comments we received in response to the FY 2017 IPPS/LTCH PPS proposed rule, we approved idarucizumab for new technology add-on payments for FY 2017 (81 FR 56897). With the new technology add-on payment application, the applicant indicated that the total operating cost of idarucizumab is $3,500. Under Sec. 412.88(a)(2), we limit new technology add-on payments to the lesser of 50 percent of the average cost of the technology, or 50 percent of the costs in excess of the MS-DRG payment for the case. As a result, the maximum new technology add-on payment for a case involving idarucizumab is $1,750. With regard to the newness criterion for idarucizumab, we considered the beginning of the newness period to commence when PRAXBIND was approved by the FDA on October 16, 2015. As discussed previously in this section, in general, we extend new technology add-on payments for an additional year only if the 3-year anniversary date of the product's entry onto the U.S. market occurs in the latter half of the upcoming fiscal year. Because the 3-year anniversary date of the entry of PRAXBIND onto the U.S. market will occur in the first half of FY 2019 (October 15, 2018), in the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20282), we proposed to discontinue new technology add-on payments for this technology for FY 2019. We invited public comments on our proposal to discontinue new technology add-on payments for idarucizumab. Comment: A few commenters supported CMS' proposal to discontinue new technology add-on payments for FY 2019 for idarucizumab. Response: We appreciate the commenters' support. After consideration of the public comments we received, we are finalizing our proposal to discontinue new technology add-on payments for idarucizumab for FY 2019. e. Stelara[supreg] (Ustekinumab) Janssen Biotech submitted an application for new technology add-on payments for the Stelara[supreg] induction therapy for FY 2018. Stelara[supreg] received FDA approval as an intravenous (IV) infusion treatment for adult patients with moderately to severe active Crohn's disease (CD) who have failed or were intolerant to treatment using immunomodulators or corticosteroids, but never failed a tumor necrosis factor (TNF) blocker, or failed or were intolerant to treatment using one or more TNF blockers. The FDA approved Stelara[supreg] on September 23, 2016. Stelara[supreg] IV is intended for induction--subcutaneous prefilled syringes are intended for maintenance dosing. Stelara[supreg] must be administered intravenously by a health care professional in either an inpatient hospital setting or an outpatient hospital setting. Stelara[supreg] for IV infusion is packaged in single 130 mg vials. Induction therapy consists of a single IV infusion dose using the following weight-based dosing regimen: Patients weighing less than (<)55 kg are administered 260 mg of Stelara[supreg] (2 vials); patients weighing more than (>)55 kg, but less than (<)85 kg are administered 390 mg of Stelara[supreg] (3 vials); and patients weighing more than (>)85 kg are administered 520 mg of Stelara[supreg] (4 vials). An average dose of Stelara[supreg] administered through IV infusion is 390 mg (3 vials). Maintenance doses of Stelara[supreg] are administered at 90 mg, subcutaneously, at 8-week intervals and may occur in the outpatient hospital setting. CD is an inflammatory bowel disease of unknown etiology, characterized by transmural inflammation of the gastrointestinal (GI) tract. Symptoms of CD may include fatigue, prolonged diarrhea with or without bleeding, abdominal pain, weight loss and fever. CD can affect any part of the GI tract including the mouth, esophagus, stomach, small intestine, and large intestine. Conventional pharmacologic treatments of CD include antibiotics, mesalamines, corticosteroids, immunomodulators, tumor necrosis alpha (TNF[alpha]) inhibitors, and anti-integrin agents. Surgery may be necessary for some patients diagnosed with CD in which conventional therapies have failed. After evaluation of the newness, costs, and substantial clinical improvement criteria for new technology add-on payments for Stelara[supreg] and consideration of the public comments we received in response to the FY 2018 IPPS/LTCH PPS proposed rule, we approved Stelara[supreg] for new technology add-on payments for FY 2018 (82 FR 38129). Cases involving Stelara[supreg] that are eligible for new technology add-on payments are identified by ICD-10-PCS procedure code XW033F3 (Introduction of other New Technology therapeutic substance into peripheral vein, percutaneous approach, new technology group 3). With the new technology add-on payment application, the applicant estimated that the average Medicare beneficiary would require a dosage of 390 mg (3 vials) at a hospital acquisition cost of $1,600 per vial (for a total of $4,800). Under Sec. 412.88(a)(2), we limit new technology add-on payments to the lesser of 50 percent of the average cost of the technology or 50 percent of the costs in excess of the MS- DRG payment for the case. As a result, the maximum new technology add- on payment amount for a case involving the use of Stelara[supreg] is $2,400. With regard to the newness criterion for Stelara[supreg], we considered the beginning of the newness period to commence when Stelara[supreg] received FDA approval as an IV infusion treatment of Crohn's disease (CD) on September 23, 2016. Because the 3-year anniversary date of the entry of Stelara[supreg] onto the U.S. market (September 23, 2019) will occur after FY 2019, in the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20282 through 20283) we proposed to continue new technology add-on payments for this technology for FY 2019. We proposed that the maximum payment for a case involving Stelara[supreg] would remain at $2,400 for FY 2019. We invited public comments on our proposal to continue new technology add-on payments for Stelara[supreg] for FY 2019. Comment: A few commenters supported CMS' proposal to continue new technology add-on payments for Stelara[supreg] for FY 2019. In addition, the applicant (manufacturer) also agreed with CMS' proposal to continue new technology add-on payments for the Stelara[supreg] for FY 2019, and noted that because the technology's 3-year anniversary date of the product's entry onto the U.S. market would not occur until September 23, 2019, it is appropriate to continue new technology add-on payments for FY 2019. Response: We appreciate the commenters' support. After consideration of the public comments [[Page 41282]] we received, we are finalizing our proposal to continue new technology add-on payments for Stelara[supreg] for FY 2019. The maximum payment for a case involving Stelara[supreg] will remain at $2,400 for FY 2019. f. VistogardTM (Uridine Triacetate) BTG International Inc. submitted an application for new technology add-on payments for the VistogardTM for FY 2017. VistogardTM was developed as an emergency treatment for fluorouracil or capecitabine overdose regardless of the presence of symptoms and for those who exhibit early-onset, severe, or life- threatening toxicity. Chemotherapeutic agent 5-fluorouracil (5-FU) is used to treat specific solid tumors. It acts upon deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) in the body, as uracil is a naturally occurring building block for genetic material. Fluorouracil is a fluorinated pyrimidine. As a chemotherapy agent, fluorouracil is absorbed by cells and causes the cell to metabolize into byproducts that are toxic and used to destroy cancerous cells. According to the applicant, the byproducts fluorodoxyuridine monophosphate (F-dUMP) and floxuridine triphosphate (FUTP) are believed to do the following: (1) Reduce DNA synthesis; (2) lead to DNA fragmentation; and (3) disrupt RNA synthesis. Fluorouracil is used to treat a variety of solid tumors such as colorectal, head and neck, breast, and ovarian cancer. With different tumor treatments, different dosages, and different dosing schedules, there is a risk for toxicity in these patients. Patients may suffer from fluorouracil toxicity/death if 5-FU is delivered in slight excess or at faster infusion rates than prescribed. The cause of overdose can happen for a variety of reasons including: Pump malfunction, incorrect pump programming or miscalculated doses, and accidental or intentional ingestion. VistogardTM is an antidote to fluorouracil toxicity and is a prodrug of uridine. Once the drug is metabolized into uridine, it competes with the toxic byproduct FUTP in binding to RNA, thereby reducing the impact FUTP has on cell death. With regard to the newness criterion, VistogardTM received FDA approval on December 11, 2015. However, as discussed in the FY 2017 IPPS/LTCH PPS final rule (81 FR 56910), due to the delay in VistogardTM's commercial availability, we considered the newness period to begin March 2, 2016, instead of December 11, 2015. The applicant noted that the VistogardTM is the first FDA- approved antidote used to reverse fluorouracil toxicity. The applicant submitted a request for a unique ICD-10-PCS procedure code and was granted approval for the following procedure code: XW0DX82 (Introduction of Uridine Triacetate into Mouth and Pharynx, External Approach, new technology group 2). The new code became effective on October 1, 2016. After evaluation of the newness, costs, and substantial clinical improvement criteria for new technology add-on payments for VistogardTM and consideration of the public comments we received in response to the FY 2017 IPPS/LTCH PPS proposed rule, we approved VistogardTM for new technology add-on payments for FY 2017 (81 FR 56912). With the new technology add-on payment application, the applicant stated that the total operating cost of VistogardTM is $75,000. Under Sec. 412.88(a)(2), we limit new technology add-on payments to the lesser of 50 percent of the average cost of the technology or 50 percent of the costs in excess of the MS-DRG payment for the case. As a result, the maximum new technology add-on payment for a case involving VistogardTM is $37,500. With regard to the newness criterion for the VistogardTM, we considered the beginning of the newness period to commence upon the entry of VistogardTM onto the U.S. market on March 2, 2016. As discussed previously in this section, in general, we extend new technology add-on payments for an additional year only if the 3-year anniversary date of the product's entry onto the U.S. market occurs in the latter half of the upcoming fiscal year. Because the 3-year anniversary date of the entry of the VistogardTM onto the U.S. market (March 2, 2019) will occur in the first half of FY 2019, in the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20283), we proposed to discontinue new technology add-on payments for this technology for FY 2019. We invited public comments on our proposal to discontinue new technology add-on payments for the VistogardTM. Comment: A few commenters supported CMS' proposal to discontinue new technology add-on payments for FY 2019 for VistogardTM. Response: We appreciate the commenters' support. After consideration of the public comments we received, we are finalizing our proposal to discontinue new technology add-on payments for VistogardTM for FY 2019. g. ZINPLAVATM (Bezlotoxumab) Merck & Co., Inc. submitted an application for new technology add- on payments for ZINPLAVATM for FY 2018. ZINPLAVATM is indicated to reduce recurrence of Clostridium difficile infection (CDI) in adult patients who are receiving antibacterial drug treatment for a diagnosis of CDI who are at high risk for CDI recurrence. ZINPLAVATM is not indicated for the treatment of the presenting episode of CDI and is not an antibacterial drug. Clostridium difficile (C-diff) is a disease-causing anaerobic, spore forming bacteria that can affect the gastrointestinal (GI) tract. Some people carry the C-diff bacterium in their intestines, but never develop symptoms of an infection. The difference between asymptomatic colonization and pathogenicity is caused primarily by the production of an enterotoxin (Toxin A) and/or a cytotoxin (Toxin B). The presence of either or both toxins can lead to symptomatic CDI, which is defined as the acute onset of diarrhea with a documented infection with toxigenic C-diff, or the presence of either toxin A or B. The GI tract contains millions of bacteria, commonly referred to as ``normal flora'' or ``good bacteria,'' which play a role in protecting the body from infection. Antibiotics can kill these good bacteria and allow the C- diff bacteria to multiply and release toxins that damage the cells lining the intestinal wall, resulting in a CDI. CDI is a leading cause of hospital-associated gastrointestinal illnesses. Persons at increased risk for CDI include people who are treated with current or recent antibiotic use, people who have encountered current or recent hospitalization, people who are older than 65 years, immunocompromised patients, and people who have recently had a diagnosis of CDI. CDI symptoms include, but are not limited to, diarrhea, abdominal pain, and fever. CDI symptoms range in severity from mild (abdominal discomfort, loose stools) to severe (profuse, watery diarrhea, severe pain, and high fevers). Severe CDI can be life-threatening and, in rare cases, can cause bowel rupture, sepsis and organ failure. CDI is responsible for 14,000 deaths per year in the United States. C-diff produces two virulent, pro-inflammatory toxins, Toxin A and Toxin B, which target host colonocytes (that is, large intestine endothelial cells) by binding to endothelial cell surface receptors via combined repetitive oligopeptide (CROP) domains. These toxins cause the release of inflammatory cytokines leading to intestinal fluid secretion and intestinal inflammation. The applicant asserted that ZINPLAVATM targets Toxin B sites within the CROP domain rather than the [[Page 41283]] C-diff organism itself. According to the applicant, by targeting C-diff Toxin B, ZINPLAVATM neutralizes Toxin B, prevents large intestine endothelial cell inflammation, symptoms associated with CDI, and reduces the recurrence of CDI. ZINPLAVATM received FDA approval on October 21, 2016, for reduction of recurrence of CDI in adult patients receiving antibacterial drug treatment for CDI and who are at high risk of CDI recurrence. ZINPLAVATM became commercially available on February 10, 2017. Therefore, the newness period for ZINPLAVATM began on February 10, 2017. The applicant submitted a request for a unique ICD-10-PCS procedure code and was granted approval for the following procedure codes: XW033A3 (Introduction of bezlotoxumab monoclonal antibody, into peripheral vein, percutaneous approach, new technology group 3) and XW043A3 (Introduction of bezlotoxumab monoclonal antibody, into central vein, percutaneous approach, new technology group 3). After evaluation of the newness, costs, and substantial clinical improvement criteria for new technology add-on payments for ZINPLAVATM and consideration of the public comments we received in response to the FY 2018 IPPS/LTCH PPS proposed rule, we approved ZINPLAVATM for new technology add-on payments for FY 2018 (82 FR 38119). With the new technology add-on payment application, the applicant estimated that the average Medicare beneficiary would require a dosage of 10mg/kg of ZINPLAVATM administered as an IV infusion over 60 minutes as a single dose. According to the applicant, the WAC for one dose is $3,800. Under Sec. 412.88(a)(2), we limit new technology add-on payments to the lesser of 50 percent of the average cost of the technology, or 50 percent of the costs in excess of the MS-DRG payment for the case. As a result, the maximum new technology add-on payment amount for a case involving the use of ZINPLAVATM is $1,900. With regard to the newness criterion for ZINPLAVATM, we considered the beginning of the newness period to commence on February 10, 2017. Because the 3-year anniversary date of the entry of ZINPLAVATM onto the U.S. market (February 10, 2020) will occur after FY 2019, in the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20283 through 20284), we proposed to continue new technology add-on payments for this technology for FY 2019. We proposed that the maximum payment for a case involving ZINPLAVATM would remain at $1,900 for FY 2019. We invited public comments on our proposal to continue new technology add-on payments for ZINPLAVATM for FY 2019. Comment: A few commenters supported CMS' proposal to continue new technology add-on payments for ZINPLAVATM for FY 2019. Response: We appreciate the commenters' support. After consideration of the public comments we received, we are finalizing our proposal to continue new technology add-on payments for ZINPLAVATM for FY 2019. The maximum new technology add-on payment for a case involving ZINPLAVATM will remain at $1,900 for FY 2019. 5. FY 2019 Applications for New Technology Add-On Payments We received 15 applications for new technology add-on payments for FY 2019. In accordance with the regulations under Sec. 412.87(c), applicants for new technology add-on payments must have FDA approval or clearance by July 1 of the year prior to the beginning of the fiscal year that the application is being considered. Since the issuance of the FY 2019 IPPS/LTCH PPS proposed rule, three applicants, Progenics Pharmaceuticals, Inc. (the applicant for AZEDRA[supreg]), Somahlution, Inc. (the applicant for DURAGRAFT[supreg]), and TherOx, Inc. (the applicant for Supersaturated Oxygen (SSO 2 ) Therapy), withdrew their applications. One applicant, Isoray Medical, Inc. and GT Medical Technologies, Inc. (the applicant for GammaTileTM), did not meet the deadline of July 1 for FDA approval or clearance of the technology and, therefore, the technology is not eligible for consideration for new technology add-on payments for FY 2019. A discussion of the remaining 11 applications is presented below. a. KYMRIAH[supreg] (Tisagenlecleucel) and YESCARTA[supreg] (Axicabtagene Ciloleucel) Two manufacturers, Novartis Pharmaceuticals Corporation and Kite Pharma, Inc. submitted separate applications for new technology add-on payments for FY 2019 for KYMRIAH (tisagenlecleucel) and YESCARTA (axicabtagene ciloleucel), respectively. Both of these technologies are CD-19-directed T-cell immunotherapies used for the purposes of treating patients with aggressive variants of non-Hodgkin lymphoma (NHL). In the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20284), we noted that KYMRIAH was approved by the FDA on August 30, 2017, for use in the treatment of patients up to 25 years of age with B-cell precursor acute lymphoblastic leukemia (ALL) that is refractory or in second or later relapse, which is a different indication and patient population than the new indication and targeted patient population for which the applicant submitted a request for approval of new technology add-on payments for FY 2019. Specifically, and as summarized in a table presented in the proposed rule and updated in the following table presented in this final rule, the new indication for which Novartis Pharmaceuticals Corporation is requesting approval for new technology add-on payments for KYMRIAH is as an autologous T-cell immune therapy indicated for use in the treatment of patients with relapsed/refractory (r/r) diffuse large B-Cell lymphoma after two or more lines of systemic therapy including diffuse large B-cell lymphoma (DLBCL) not eligible for autologous stem cell transplant (ASCT). In addition, we indicated that as of the time of the development of the proposed rule, Novartis Pharmaceuticals Corporation had been granted Breakthrough Therapy designation by the FDA, and was awaiting FDA approval for the use of KYMRIAH under this new indication. The updated table that follows reflects that Novartis Pharmaceuticals Corporation received FDA approval for the use of KYMRIAH under this new indication on May 1, 2018. We also noted that Kite Pharma, Inc. previously submitted an application for approval for new technology add-on payments for FY 2018 for KTE-C19 for use as an autologous T-cell immune therapy in the treatment of adult patients with r/r aggressive B-cell NHL who are ineligible for ASCT. However, Kite Pharma, Inc. withdrew its application for KTE-C19 prior to publication of the FY 2018 IPPS/LTCH PPS final rule. Kite Pharma, Inc. resubmitted an application for approval for new technology add-on payments for FY 2019 for KTE-C19 under a new name, YESCARTA, for the same indication. Kite Pharma, Inc. received FDA approval for this original indication and treatment use of YESCARTA on October 18, 2017. (We refer readers to the following updated table for a comparison of the indications and FDA approvals for KYMRIAH and YESCARTA).

YESCARTA (Kite Pharma, Inc.)............ None...................................... N/A. ---------------------------------------------------------------------------------------------------------------- We note that procedures involving the KYMRIAH and YESCARTA therapies are both reported using the following ICD-10-PCS procedure codes: XW033C3 (Introduction of engineered autologous chimeric antigen receptor t-cell immunotherapy into peripheral vein, percutaneous approach, new technology group 3); and XW043C3 (Introduction of engineered autologous chimeric antigen receptor t-cell immunotherapy into central vein, percutaneous approach, new technology group 3). We further note that, in section II.F.2.d. of the preamble of this final rule, we are finalizing our proposal to assign cases reporting these ICD-10-PCS procedure codes to Pre-MDC MS-DRG 016 for FY 2019 and to revise the title of this MS-DRG to (Autologous Bone Marrow Transplant with CC/MCC or T-cell Immunotherapy). We refer readers to section II.F.2.d. of the preamble of this final rule for a complete discussion of these final policies. According to the applicants, patients with NHL represent a heterogeneous group of B-cell malignancies with varying patterns of behavior and response to treatment. B-cell NHL can be classified as either an aggressive, or indolent disease, with aggressive variants including DLBCL; primary mediastinal large B-cell lymphoma (PMBCL); and transformed follicular lymphoma (TFL). Within diagnoses of NHL, DLBCL is the most common subtype of NHL, accounting for approximately 30 percent of patients who have been diagnosed with NHL, and survival without treatment is measured in months.\6\ Despite improved therapies, only 50 to 70 percent of newly diagnosed patients are cured by standard first-line therapy alone. Furthermore, r/r disease continues to carry a poor prognosis because only 50 percent of patients are eligible for autologous stem cell transplantation (ASCT) due to advanced age, poor functional status, comorbidities, inadequate social support for recovery after ASCT, and provider or patient choice.\7\ \8\ \9\ \10\ Of the roughly 50 percent of patients that are eligible for ASCT, nearly 50 percent fail to respond to prerequisite salvage chemotherapy and cannot undergo ASCT.\11\ \12\ \13\ \14\ Second-line chemotherapy regimens studied to date include rituximab, ifosfamide, carboplatin and etoposide (R-ICE), and rituximab, dexamethasone, cytarabine, and cisplatin (R-DHAP), followed by consolidative high-dose therapy (HDT)/ ASCT. Both regimens offer similar overall response rates (ORR) of 51 percent with 1 in 4 patients achieving long-term complete response (CR) at the expense of increased toxicity.\15\ Second-line treatment with dexamethasone, high-dose cytarabine, and cisplatin (DHAP) is considered a standard chemotherapy regimen, but is associated with substantial treatment-related toxicity.\16\ For patients who experience disease progression during or after primary treatment, the combination of HDT/ ASCT remains the only curative option.\17\ According to the applicants, given the modest response to second-line therapy and/or HDT/ASCT, the population of patients with the highest unmet need is those with chemorefractory disease, which include DLBCL, PMBCL, and TFL. These [[Page 41285]] patients are defined as either progressive disease (PD) as best response to chemotherapy, stable disease as best response following greater than or equal to 4 cycles of first-line or 2 cycles of later- line therapy, or relapse within less than or equal to 12 months of ASCT.\18\ Based on these definitions and available data from a multi- center retrospective study (SCHOLAR-1), chemorefractory disease treated with current and historical standards of care has consistently poor outcomes with an ORR of 26 percent and median overall survival (OS) of 6.3 months.\19\ --------------------------------------------------------------------------- \6\ Chaganti, S., et al., ``Guidelines for the management of diffuse large B-cell lymphoma,'' BJH Guideline, 2016.

Novartis Pharmaceuticals Corporation describes KYMRIAH as a CD-19-directed genetically modified autologous T-cell immunotherapy which utilizes peripheral blood T-cells, which have been reprogrammed with a transgene encoding, a chimeric antigen receptor (CAR), to identify and eliminate CD-19-expressing malignant and normal cells. Upon binding to CD-19-expressing cells, the CAR transmits a signal to promote T-cell expansion, activation, target cell elimination, and persistence of KYMRIAH cells. The transduced T-cells expand in vivo to engage and eliminate CD-19-expressing cells and may exhibit immunological endurance to help support long-lasting remission.\20\ \21\ \22\ \23\ At the time the applicant submitted its application for new technology add-on payments, the applicant conveyed that no other agent currently used in the treatment of patients with r/ r DLBCL employs gene modified autologous cells to target and eliminate malignant cells. --------------------------------------------------------------------------- \20\ KYMRIAHTM [prescribing information], East Hanover, NJ: Novartis Pharmaceuticals Corp, 2017. \21\ Kalos, M., Levine, B.L., Porter, D.L., et al., ``T-cells with chimeric antigen receptors have potent antitumor effects and can establish memory in patients with advanced leukemia,'' Sci Transl Med, 2011, vol. 3(95), pp, 95ra73. \22\ FDA Briefing Document.

YESCARTA is not indicated for the treatment of patients with primary central nervous system lymphoma. The applicant for YESCARTA described the technology as a CD-19-directed genetically modified autologous T-cell immunotherapy that binds to CD-19-expressing cancer cells and normal B-cells. These normal B-cells are considered to be non-essential tissue, as they are not required for patient survival. According to the applicant, studies demonstrated that following anti- CD-19 CAR T-cell engagement with CD-19-expressing target cells, the CD- 28 and CD-3-zeta co-stimulatory domains activate downstream signaling cascades that lead to T-cell activation, proliferation, acquisition of effector functions and secretion of inflammatory cytokines and chemokines. This sequence of events leads to the elimination of CD-19- expressing tumor cells. Both applicants expressed that their technology is the first treatment of its kind for the targeted adult population. In addition, both applicants asserted that their technology is new and does not use a substantially similar mechanism of action or involve the same treatment indication as any other currently FDA-approved technology. In the FY 2019 IPPS/LTCH PPS proposed rule, we noted that, at the time each applicant submitted its new technology add-on payment application, neither technology had received FDA approval for the indication for which the applicant requested approval for the new technology add-on payment. We indicated that KYMRIAH had been granted Breakthrough Therapy designation for the use in the treatment of patients for the additional indication that is the subject of its new technology add-on application and, as of the time of the development of the proposed rule, was awaiting FDA approval. As noted previously, the applicant for KYMRIAH received approval for this additional indication on May 1, 2018. We further noted in the proposed rule that, YESCARTA received FDA approval for use in the treatment of patients and the indication stated in its application on October 18, 2017, after each applicant submitted its new technology add-on payment application. As noted, according to both applicants, KYMRIAH and YESCARTA are the first CAR T-cell immunotherapies of their kind. Because potential cases representing patients who may be eligible for treatment using KYMRIAH and YESCARTA would group to the same MS-DRGs (because the same ICD-10-CM diagnosis codes and ICD-10-PCS procedures codes are used to report treatment using either KYMRIAH or YESCARTA), and we believed that these technologies are intended to treat the same or similar disease in the same or similar patient population, and are purposed to achieve the same therapeutic outcome using the same or similar mechanism of action, we disagreed with the applicants and believed these two technologies are substantially similar to each other and that it was appropriate to evaluate both technologies as one application for new technology add-on payments under the IPPS. For these reasons, and as discussed further below, we stated that we intended to make one determination regarding approval for new technology add-on payments that would apply to both applications, and in accordance with our policy, would use the earliest market availability date submitted as the beginning of the newness period for both KYMRIAH and YESCARTA. Several public commenters submitted comments regarding whether the technologies are substantially similar to each other in response to the proposed rule and we summarize and respond to the public comments below. With respect to the newness criterion, as previously stated, YESCARTA received FDA approval on October 18, 2017. According to the applicant, prior to FDA approval, YESCARTA had been available in the U.S. only on an investigational basis under an investigational new drug (IND) application. For the same IND patient population, and until commercial availability, YESCARTA was available under an Expanded Access Program (EAP) which started on May 17, 2017. The applicant stated that it did not recover any costs associated with the EAP. According to the applicant, the first commercial shipment of YESCARTA was received by a certified treatment center on November 22, 2017. As discussed previously, KYMRIAH received FDA approval May 1, 2018, for use in the treatment of patients diagnosed with r/r DLBCL that are not eligible for ASCT. Additionally, as noted in the proposed rule, KYMRIAH was previously granted Breakthrough Therapy designation by the FDA. We stated in the proposed rule that we believe that, in accordance with our policy, if these technologies are substantially similar to each other, it is appropriate to use the earliest market [[Page 41286]] availability date submitted as the beginning of the newness period for both technologies. Therefore, based on our policy, with regard to both technologies, if the technologies are approved for new technology add- on payments, we stated that we believe that the beginning of the newness period would be November 22, 2017. We stated in the proposed rule that, because we believe these two technologies are substantially similar to each other, we believe it is appropriate to evaluate both technologies as one application for new technology add-on payments under the IPPS. The applicants submitted separate cost and clinical data, and we reviewed and discussed each set of data separately. However, we stated that we intended to make one determination regarding new technology add-on payments that would apply to both applications. We stated that we believe that this is consistent with our policy statements in the past regarding substantial similarity. Specifically, we have noted that approval of new technology add-on payments would extend to all technologies that are substantially similar (66 FR 46915), and we believe that continuing our current practice of extending new technology add-on payments without a further application from the manufacturer of the competing product, or a specific finding on cost and clinical improvement if we make a finding of substantial similarity among two products is the better policy because we avoid--Creating manufacturer-specific codes for substantially similar products; Requiring different manufacturers of substantially similar products to submit separate new technology add-on payment applications; Having to compare the merits of competing technologies on the basis of substantial clinical improvement; and Bestowing an advantage to the first applicant representing a particular new technology to receive approval (70 FR 47351). We stated that, if substantially similar technologies are submitted for review in different (and subsequent) years, rather than the same year, we would evaluate and make a determination on the first application and apply that same determination to the second application. However, we stated that, because the technologies have been submitted for review in the same year and we believe they are substantially similar to each other, we believe that it is appropriate to consider both sets of cost data and clinical data in making a determination, and we do not believe that it is possible to choose one set of data over another set of data in an objective manner. We received public comments regarding our proposal to evaluate KYMRIAH and YESCARTA as one application for new technology add-on payments under the IPPS and we summarize and respond to these public comments below. In the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20284), we stated that we believe that KYMRIAH and YESCARTA are substantially similar to each other for purposes of analyzing these two applications as one application. As discussed in the proposed rule, we stated that we also need to determine whether KYMRIAH and YESCARTA are substantially similar to existing technologies prior to their approval by the FDA and their release onto the U.S. market. As discussed earlier, if a technology meets all three of the substantial similarity criteria, it would be considered substantially similar to an existing technology and would not be considered ``new'' for purposes of new technology add-on payments. With respect to the first criterion, whether a product uses the same or a similar mechanism of action to achieve a therapeutic outcome, the applicant for KYMRIAH asserted that its unique design, which utilizes features that were not previously included in traditional cytotoxic chemotherapeutic or immunotherapeutic agents, constitutes a new mechanism of action. The deployment mechanism allows for identification and elimination of CD-19-expressing malignant and non- malignant cells, as well as possible immunological endurance to help support long-lasting remission.\24\ \25\ \26\ \27\ The applicant provided context regarding how KYMRIAH's unique design contributes to a new mechanism of action by explaining that peripheral blood T-cells, which have been reprogrammed with a transgene encoding, a CAR, identify and eliminate CD-19-expressing malignant and nonmalignant cells. As explained by the applicant, upon binding to CD-19-expressing cells, the CAR transmits a signal to promote T-cell expansion, activation, target cell elimination, and persistence of KYMRIAH cells.\28\ \29\ \30\ According to the applicant, transduced T-cells expand in vivo to engage and eliminate CD-19-expressing cells and may exhibit immunological endurance to help support long-lasting remission.\31\ \32\ \33\ --------------------------------------------------------------------------- \24\ KYMRIAH [prescribing information].

Therefore, the applicant believed that YESCARTA's mechanism of action is distinct and unique from any other cancer drug or biologic that is currently approved for use in the treatment of patients who have been diagnosed with aggressive B-cell NHL, namely single-agent or combination chemotherapy regimens. At the time of the development of the proposed rule, the applicant also pointed out that YESCARTA was the only available therapy that has been granted FDA approval for the treatment of adult patients with r/r large B-cell lymphoma after two or more lines of systemic therapy, including DLBCL not otherwise specified, PMBCL, high grade B-cell lymphoma, and DLBCL arising from follicular lymphoma. With respect to the second and third criteria, whether a product is assigned to the same or a different MS-DRG and whether the new use of the technology involves the treatment of the same or similar type of disease and the same or similar patient population, the applicant [[Page 41287]] for KYMRIAH indicated that the technology is used in the treatment of the same patient population, and potential cases representing patients that may be eligible for treatment using KYMRIAH would be assigned to the same MS-DRGs as cases involving patients with a DLBCL diagnosis. Potential cases representing patients that may be eligible for treatment using KYMRIAH map to 437 separate MS-DRGs, with the top 20 MS-DRGs covering approximately 68 percent of all patients who have been diagnosed with DLBCL. For patients with DLBCL and who have received chemotherapy during their hospital stay, the target population mapped to 8 separate MS-DRGs, with the top 2 MS-DRGs covering over 95 percent of this population: MS-DRGs 847 (Chemotherapy without Acute Leukemia as Secondary Diagnosis with CC), and 846 (Chemotherapy without Acute Leukemia as Secondary Diagnosis with MCC). The applicant for YESCARTA submitted findings that potential cases representing patients that may be eligible for treatment using YESCARTA span 15 unique MS-DRGs, 8 of which contain more than 10 cases. The most common MS-DRGs were: MS-DRGs 840 (Lymphoma and Non-Acute Leukemia with MCC), 841 (Lymphoma and Non- Acute Leukemia with CC), and 823 (Lymphoma and Non-Acute Leukemia with other O.R. Procedures with MCC). These 3 MS-DRGs accounted for 628 (76 percent) of the 827 cases. While the applicants for KYMRIAH and YESCARTA submitted different findings regarding the most common MS-DRGs to which potential cases representing patients who may be eligible for treatment involving their technology would map, we stated in the proposed rule that we believe that, under the current MS-DRGs (FY 2018), potential cases representing patients who may be eligible for treatment involving either KYMRIAH or YESCARTA would map to the same MS-DRGs because the same ICD-10-CM diagnosis codes and ICD-10-PCS procedures codes will be used to report cases for patients who may be eligible for treatment involving KYMRIAH and YESCARTA. Furthermore, as noted above, we proposed, and are finalizing, that cases reporting these ICD-10-PCS procedure codes would be assigned to MS-DRG 016 for FY 2019. Therefore, under this proposal (and our finalized policy), for FY 2019, cases involving the utilization of KYMRIAH and YESCARTA would continue to map to the same MS-DRGs. The applicant for YESCARTA also addressed the concern expressed by CMS in the FY 2018 IPPS/LTCH PPS proposed rule regarding Kite Pharma Inc.'s FY 2018 new technology add-on payment application for the KTE- C19 technology (82 FR 19888). At the time, CMS expressed concern that KTE-C19 may use the same or similar mechanism of action as the Bi- Specific T-Cell engagers (BiTE) technology. The applicant for YESCARTA explained that YESCARTA has a unique and distinct mechanism of action that is substantially different from BiTE's or any other drug or biologic currently assigned to any MS-DRG in the FY 2016 MedPAR Hospital Limited Data Set. In providing more detail regarding how YESCARTA is different from the BiTE technology, the applicant explained that the BiTE technology is not an engineered autologous T-cell immunotherapy derived from a patient's own T-cells. Instead, it is a bi-specific T-cell engager that recognizes CD-19 and CD-3 cancer cells. Unlike engineered T-cell therapy, BiTE does not have the ability to enhance the proliferative and cytolytic capacity of T-cells through ex- vivo engineering. Further, BiTE is approved for the treatment of patients who have been diagnosed with Philadelphia chromosome-negative relapsed or refractory B-cell precursor acute lymphoblastic leukemia (ALL) and is not approved for patients with relapsed or refractory large B-cell lymphoma, whereas YESCARTA is indicated for use in the treatment of adult patients with r/r aggressive B-cell NHL who are ineligible for ASCT. The applicant for YESCARTA also indicated that its mechanism of action is not the same or similar to the mechanism of action used by KYMRIAH's currently available FDA-approved CD-19-directed genetically modified autologous T-cell immunotherapy indicated for use in the treatment of patients up to 25 years of age with B-cell precursor acute lymphoblastic leukemia (ALL) that is refractory or in second or later relapse.\34\ The applicant for YESCARTA stated that the mechanism of action is different from KYMRIAH's FDA-approved therapy because the spacer, transmembrane and co-stimulatory domains of YESCARTA are different from those of KYMRIAH. The applicant explained that YESCARTA is comprised of a CD-28 co-stimulatory domain and KYMRIAH has 4-1BB co- stimulatory domain. Further, the applicant stated the manufacturing processes of the two immunotherapies are also different, which may result in cell composition differences leading to possible efficacy and safety differences. --------------------------------------------------------------------------- \34\ Food and Drug Administration. Available at: www.accessdata.fda.gov/scripts/opdlisting/oopd/. --------------------------------------------------------------------------- We stated in the proposed rule that while the applicant for YESCARTA stated how its technology is different from KYMRIAH, because both technologies are CD-19-directed T-cell immunotherapies used for the purpose of treating patients with aggressive variants of NHL, we believe that YESCARTA and KYMRIAH are substantially similar treatment options. Furthermore, in the FY 2019 IPPS/LTCH PPS proposed rule, we also stated that we were concerned there may be an age overlap (18 to 25) between the two different patient populations for the currently approved KYMRIAH technology and YESCARTA technology. We stated in the proposed rule, which was issued prior to the approval for a second indication (adult patients), that the indication for the KYMRIAH technology is for use in the treatment of patients who are up to 25 years of age and the YESCARTA technology is indicated for use in the treatment of adult patients. We noted in the proposed rule that the applicant asserted that YESCARTA is not substantially similar to KYMRIAH. We stated that under this scenario, if both YESCARTA and KYMRIAH meet all of the new technology add-on payment criteria and are approved for new technology add-on payments for FY 2019, for purposes of making the new technology add-on payment, because procedures utilizing either YESCARTA or KYMRIAH CAR T-cell therapy drugs are reported using the same ICD-10-PCS procedure codes, in order to accurately pay the new technology add-on payment to hospitals that perform procedures utilizing either technology, it may be necessary to use alternative coding mechanisms to make the new technology add-on payments. In the FY 2019 IPPS/LTCH PPS proposed rule, CMS invited comments on alternative coding mechanisms to make the new technology add-on payments, if necessary. We also invited public comments on whether KYMRIAH and YESCARTA are substantially similar to existing technologies and whether the technologies meet the newness criterion. Comment: The applicants for KYMRIAH and YESCARTA each provided comments regarding whether KYMRIAH and YESCARTA were substantially similar to the other, or to any existing technology. Additional commenters also submitted comments. [[Page 41288]] The applicant for YESCARTA stated that it continued to believe each technology consists of notable differences in the construction, as well as manufacturing processes and successes that may lead to differences in activity. The applicant encouraged CMS to evaluate YESCARTA as a separate new technology add-on payment application and approve separate new technology add-on payments for YESCARTA, effective October 1, 2018, and to not move forward with a single new technology add-on payment evaluation determination that covers both CAR T-cell therapies, YESCARTA and KYMRIAH. The applicant stated that the transmembrane domain of YESCARTA is comprised of a fragment of CD-28 co-stimulatory molecule, including an extracellular hinge domain, which provides structural flexibility for optimal binding of the target antigen by the scFV target binding region. The applicant further stated that, in contrast, KYMRIAH consists of a spacer and a transmembrane domain, which are derived from CD8-a. The applicant for YESCARTA believed that, the spacer provides a flexible link between the scFv and the transmembrane domain, which then accommodates different orientations of the antigen binding domain upon CD19 antigen recognition. The applicant stated that these differences in the origin of the transmembrane component between the YESCARTA and KYMRIAH may be one of the differences which lead to differentiation in CAR function and resulting activity between the two CAR constructs, which will be described later in this section. The applicant for YESCARTA believed perhaps the most critical difference between the two technologies, YESCARTA and KYMRIAH, may be that of the co-stimulatory domains, which connect the extracellular scFv antigen binding domain to the cytoplasmic CD3-zeta downstream signaling domain. The applicant explained that, for YESCARTA, the technology is derived from the intracellular domains of co-stimulatory protein CD-28. However, for KYMRIAH, in contrast, the technology is derived from the co-stimulatory protein 4-1BB (CD137). The applicant believed that, although clear mechanisms are unknown, it is surmised that the difference in co-stimulatory region of the two CAR products may be responsible for differences in activity. The applicant stated that the ongoing hypothesis for these differences are based on differentially affecting CAR T-cell cytokine production, expansion, cytotoxicity and persistence after administration. The applicant for YESCARTA also described an additional concept regarding the manufacturing process that it believed supported why the two technologies were different. The applicant explained that both, YESCARTA and KYMRIAH, are prepared from the patient's peripheral blood mononuclear cells, which are obtained via a standard leukapheresis procedure. However, the applicant stated that, with YESCARTA, the mononuclear cells are then enriched for T-cells and activated with anti-CD-3 antibody in the presence of IL-2 then transduced with the replication incompetent y-retroviral vector containing the anti-CD-19 CAR transgene. The applicant further explained that the transduced T- cells are expanded in cell culture, washed, formulated into a suspension, and cryopreserved. The applicant for YESCARTA believed that, in contrast, KYMRIAH uses anti CD-3/anti CD-28 coated magnetic beads for T-cell enrichment and activation, rather than anti-CD-3 antibody and IL-2, which are removed after CAR T-cell expansion and prior to harvest. The applicant explained that a further difference in the manufacturing of KYMRIAH is the use of lentiviral vector in the anti-CD-19 CAR gene transduction rather than a y-retroviral vector, as used for YESCARTA in manufacturing. The applicant stated that both y- retroviral or lentiviral vectors can permanently insert DNA into the genome. However, lentiviral vectors are capable of transducing quiescent cells, while y-retroviral vectors require cells in mitosis. According to the applicant, the manufacturing success in clinical trials is also different with results showing median turnaround time of 17 days for YESCARTA, with 99 percent success rate versus median turnaround time of 113 days, with 93 percent success rate for KYMRIAH. The applicant for YESCARTA further stated that, if CMS decides to establish one new technology add-on payment determination and approval for both CAR T-cell therapies, the add-on payments should be structured to ensure that payment does not hinder access in any way for patients to receive the most appropriate cell therapy and use of YESCARTA and KYMRIAH can be uniquely and individually identified in the Medicare inpatient data. Other commenters believed that the two CAR T-cell technologies should be considered as separate new technology add-on payment applications because the technologies' indications are approved for two different patient populations and diagnoses. The commenters stated that, while the approval for one of the diagnoses for adults is the same for KYMRIAH and YESCARTA, KYMRIAH has also been approved for treating children and, therefore, that should be reasoning to consider the application separately. Additionally, commenters stated that the pricing of both medications varies based on the patient population, and encouraged CMS to recognize this discrepancy when determining approval of new technology add-on payment and establishing adequate payments rates. Commenters agreed with CMS' conclusion that it is appropriate to consider both sets of cost and clinical data when determining whether the standard criteria for new technology add-on payments for KYMRIAH and YESCARTA were met, but also encouraged CMS to consider evaluation and determination of both technologies as separate applications. Some commenters disagreed with CMS' views of the YESCARTA and KYMRIAH with respect to substantial similarity and expressed concerns with CMS' conclusion that the two CAR T-cell therapies are substantially similar to each other. The commenters believed that, because each therapy has received separate FDA Breakthrough designations, is approved based on separate Biological License Applications, and may likely be used in the treatment of different patient populations in different sites of care, consideration for approval of new technology add-on payments should be based on separate applications. Commenters further believed that, for purposes of meeting the newness criterion, each new technology add-on payment application must be treated as being unique. Despite these concerns, commenters supported CMS creating a new MS-DRG for procedures and cases representing patients receiving treatment involving CAR T-cell therapies, and recognized that each of the CAR T-cell therapies would be used in the treatment of cases representing patients that would be assigned to the same MS-DRG. Several commenters disagreed with CMS' determination that the applications for KYMRIAH and YESCARTA are similar enough to warrant consideration as a single new technology add-on payment application, and recommended CMS consider the applications separately. Commenters believed that because KYMRIAH received FDA approval for the use in the treatment of patients diagnosed with [[Page 41289]] r/r DLBCL on May 1, 2018, the beginning of the newness period for KYMRIAH for cases reporting the ICD-10-PCS procedure codes representing patients diagnosed with r/r DLBCL should not be the same as YESCARTA, which began November 22, 2017. Commenters stated that equating the two beginning dates for the start of the newness periods will prematurely shorten the new technology add-on payment period for KYMRIAH's new patient population, which commenters believed would wrongfully withhold anticipated payments from hospitals. Commenters also recommended that, if CMS finalized its position to consider KYMRIAH and YESCARTA as one application, to use the approval date for KYMRIAH as the beginning of the newness period to avoid any inappropriate shortening of the new technology add-on payment length. Other commenters further cautioned CMS that combining the new technology add-on payment applications' evaluation and determination for these two therapies would create precedent that may make it unlikely for future CAR T-cell therapies to be considered distinct from existing CAR T-cell therapies, or substantially similar. As a result, the commenters believed that, if CMS finalized its proposal to make a combined decision for KYMRIAH and YESCARTA, it is more likely that future CAR T-cell therapies will not qualify for new technology add-on payments. The commenters noted that, to mitigate any potential negative impact if CMS combines both the applications and makes its determination, it would be important for CMS to leave open the option for future CAR T-cell therapies to apply for and receive approval of new technology add-on payments, regardless of the decision made for the current applications under consideration. Some commenters believed that section 1886(d)(5)(K) of the Act does not appear to clearly authorize CMS to jointly evaluate KYMRIAH and YESCARTA, which were submitted by separate manufacturers, as separate new technology add-on payment applications for two different products approved by FDA under two separate Biologics License Applications with distinct clinical and cost data submissions. The commenters believed that CMS' assessment appeared concentrated on a handful of perceived similarities in the mechanism of action and the patient and disease categories between the two newly approved CAR T-cell products. Commenters stated that this focused approach appeared to give little weight to the distinctions in the manufacturing process and co- stimulatory domains between the two CAR T-cell therapies, which obscures the important distinctions in how the different CAR T-cell technologies have been refined and optimized. The commenters further stated that CMS' evaluation also does not fully account for the difference in clinical profiles of these two agents. Other commenters believed that failure to recognize the legitimate distinctions and technological innovations reflected by CAR T-cell therapy--and inherent across different CAR T-cell treatments, such as KYMRIAH and YESCARTA, could artificially restrict access to new technology add-on payments for these new and promising technologies. Commenters recommended CMS encourage development of medical innovation by applying the new technology add-on payment ``newness'' criterion in a way that recognizes the unique, novel, and distinct nature of the CAR T-cell technology. In evaluating the new technology add-on payment applications for KYMRIAH and YESCARTA, some commenters believed that CMS may be overlooking the significant ways these two technologies represent a substantial medical advancement compared to existing therapies, most of which patients have already failed, before they go on to receive treatment involving CAR T-cell therapy. The commenters stated that CMS appeared to be unduly focusing on the perceived similarities between the two newly approved CAR T-cell therapies versus the advancement the technologies represent over existing therapies. The commenters encouraged CMS to recognize the ways in which KYMRIAH and YESCARTA significantly differ from existing technologies and to further apply the ``newness'' eligibility requirement for new technology add-on payments in a manner that does not unnecessarily discourage the availability of new technology add-on payments for these newly approved CAR T-cell therapies that represent significant clinical advantages over existing treatments. The applicant for KYMRIAH stated that, at the time it submitted its new technology add-on payment application and as summarized in the FY 2019 IPPS/LTCH PPS proposed rule, similar to the applicant for YESCARTA, it believed the two technologies were not substantially similar to the other, or to other cancer drugs or biologics currently approved for use in the treatment of aggressive B-cell NHL and, therefore, met the newness criterion. However, the applicant acknowledged that, since the date it submitted its new technology add- on payment application both technologies, YESCARTA and KYMRIAH, have received FDA approval for the technologies' intended indications. The applicant for KYMRIAH further indicated that, based on FDA's recent approval, it agreed with CMS that KYMRIAH is substantially similar to YESCARTA, as defined by the new technology add-on payment application evaluation criteria. The applicant for KYMRIAH detailed how it believed the technology is substantially similar to YESCARTA with respect to each criterion pertaining to substantial similarity. With regard to the first criterion, whether YESCARTA and KYMRIAH use the same or a similar mechanism of action to achieve a therapeutic action, the applicant stated that, although KYMRIAH's and YESCARTA's mechanisms of actions are distinct and unique from any other cancer drug or biologic that is currently FDA-approved, namely single-agent or combination chemotherapy regimens, the applicant believed KYMRIAH and YESCARTA use the same or similar mechanisms of action to achieve the therapeutic outcome. To further support the assertion that the two technologies are substantially similar to one another, the applicant for KYMRIAH also provided the FDA-approved prescribing information (``12.1 Mechanism of Action'') issued for KYMRIAH and YESCARTA describing the mechanisms of actions as being the same or similar for both technologies in the following manner: [ssquf] KYMRIAH: KYMRIAH is a CD19-directed genetically modified autologous T cell immunotherapy which involves reprogramming a patient's own T cells with a transgene encoding a chimeric antigen receptor (CAR) to identify and eliminate CD-19-expressing malignant and normal cells. The CAR is comprised of a murine single-chain antibody fragment which recognizes CD-19 and is fused to intracellular signaling domains from 4-1BB (CD137) and CD3 zeta. The CD3 zeta component is critical for initiating T-cell activation and antitumor activity, while 4-1BB enhances the expansion and persistence of KYMRIAH. Upon binding to CD-19-expressing cells, the CAR transmits a signal to promote T-cell expansion, activation, target cell elimination, and persistence of the KYMRIAH cells. [ssquf] YESCARTA: YESCARTA, a CD-19-directed genetically modified autologous T-cell immunotherapy, binds to CD-19-expressing cancer cells and normal B cells. Studies [[Page 41290]] demonstrated that following anti-CD-19 CAR T cell engagement with CD- 19-expressing target cells, the CD28 and CD3-zeta co-stimulatory domains activate downstream signaling cascades that lead to T-cell activation, proliferation, acquisition of effector functions and secretion of inflammatory cytokines and chemokines. This sequence of events leads to killing of CD-19-expressing cells. In a summary of the FDA-approved prescribing information, the applicant further noted that, within the FDA-approved prescribing information, both KYMRIAH and YESCARTA are CD-19-directed genetically modified autologous T-cell immunotherapies that bind to CD-19- expressing cancer cells and normal B cells. Upon binding to CD-19- expressing cells, the respective CARs transmit a signal to promote T cell expansion, activation, and target cell elimination. In response to the differences between KYMRIAH and YESCARTA related to spacer, transmembrane and co-stimulatory domains, which were stated by the applicant for YESCARTA, the applicant for KYMRIAH believed that, although there are structural differences that impact aspects of how the treatment effect is achieved, the overall mechanisms of actions of the two CAR T-cell therapy products are similar. The applicant explained that in defining drug classes, the FDA provided guidance that a class defined by mechanism of action would include drugs that have similar pharmacologic action at the receptor, membrane or tissue level. The applicant indicated that KYMRIAH is a cellular immunotherapy generated by gene modification of autologous donor T-cells. Further, the applicant for KYMRIAH stated that through the process of apheresis, leukocytes are harvested from the patient and undergo a process of ex- vivo gene transfer in which a CAR is introduced by lentiviral transduction. The applicant further explained that the CAR construct contains an antigen binding region designed to target CD-19, a co- stimulatory domain known as 4-1BB and a signaling domain called CD-3- zeta. The applicant stated that once transferred, the patient's T-cells will express the CAR construct anti-CD-19 4-1BB/CD-3-zeta, and undergo ex-vivo expansion. The applicant for KYMRIAH stated that both, KYMRIAH and YESCARTA, utilize a gene transfer process to modify autologous patient immune cells with a chimeric antigen receptor capable of directing immune mediated killing at a pre-specified target. The applicant further explained that both technologies accomplish their pharmacological effect through the use of three specialized domains, which are structurally different, but achieve similar environmental interactions. The applicant indicated that, in both agents, the antigen binding domain identifies CD-19 and, therefore, the interaction between the agent and its environment begins with the same receptor target interaction. Additionally, the applicant noted that both KYMRIAH and YESCARTA induce T-cell mediated cell death of the bound tumor cell by activating the T-cell expressing the CAR through the signaling domain, which is common to both agents and, therefore, at the tissue level, both generate a pharmacological impact by producing T-cell mediated apoptosis. The applicant for KYMRIAH stated that the pharmacological effect of these two agents is attained through tumor directed expansion of CAR T-cells and the development of memory T-cells that allow for potential long-term persistence and immunosurveillance. The applicant believed that, in both agents, this is achieved through the use of a co-stimulatory domain, which leads to the secretion of inflammatory substances such as cytokines, chemokines and growth factors, which induce T-cell proliferation and differentiation. The applicant for KYMRIAH stated that, although it agreed with the applicant for YESCARTA\'\s assertion that 41BB and CD-28 are both structurally and functionally different and that at a micro level they generate a different metabolic profile and stimulate different types of memory T- cell, on a macroscopic level the general impact is ``substantially similar'' in that the mechanisms of actions allow for expansion and memory, which yield tumor-directed killing of the target tissue and memory T-cell generation for longer duration response that can be expected with a traditional biologic agent. The applicant further believed that, while the manufacturing process, safety and efficacy outcomes of any two members of a class of drugs may differ, these factors do not impact the mechanism of action. With regard to the second criterion, whether YESCARTA and KYMRIAH will be assigned to the same or a different MS-DRG, the applicant stated that this criterion is met because cases representing patients eligible for treatment involving both, KYMRIAH and YESCARTA, will be reported using the same ICD-10-PCS procedure codes (XW033C3 and XW043C3) and will be assigned to the same MS-DRG--Pre-MDC MS-DRG 016 (as discussed in section II.F.2.d. of the preamble of this final rule). With regard to the third criterion, whether YESCARTA[supreg] and KYMRIAH[supreg] will be used to treat the same or similar patient population, the applicant stated that both, KYMRIAH and YESCARTA, are FDA approved to treat adult patients diagnosed with r/r aggressive B- cell NHL in the same or similar patient population. The applicant, in summary, agreed with CMS' conclusion that KYMRIAH is ``substantially similar'' to YESCARTA, as defined by CMS, because both technologies are: (1) Intended to treat the same or similar disease in the same or similar patient population; (2) purposed to achieve the same therapeutic outcome using the same or similar mechanism of action; and (3) would be assigned to the same MS-DRGs. However, the applicant stated that, despite being ``substantially similar'' technologies, KYMRIAH and YESCARTA are not ``substantially similar'' to any other existing technology and, therefore, it believed KYMRIAH met the newness criterion. Other commenters, generally, agreed that both, KYMRIAH and YESCARTA, are substantially similar technologies. One commenter stated that it agreed with CMS' approach on both clinical and policy grounds because given the promises and perils of both therapies, the surrounding coverage and payment issues present to be the same and that will also be the case for the successor drugs expected to soon achieve FDA approval and enter the U.S. market. The commenter explained that consideration of KYMRIAH and YESCARTA as one new technology add-on payment application simplifies the newness test because both technologies were assigned an ICD-10-PCS procedure code in 2017, and cases involving the utilization of the technologies and procedures reporting the ICD-10-PCS procedure codes will be assigned to the same MS-DRG, effective with the beginning of FY 2019 on October 1, 2018. The commenter also noted that, CMS indicated that November 22, 2017, would be the beginning date for the ``newness'' period because it marks the first delivery of YESCARTA to eligible treatment centers. The commenter believed this date was somewhat arbitrary, but did not provide an alternative date for consideration and, therefore, agreed that KYMRIAH and YESCARTA should be considered together as one new technology add-on payment application, both technologies met the criterion for newness, and the newness period appropriately begins on November 22, 2017. The commenter stated that, if approved for new [[Page 41291]] technology add-on payments, this newness period should grant CMS and the public sufficient time under the MS-DRG recalibration and the new technology add-on payment policies to determine whether MS-DRG 016 is an appropriate MS-DRG assignment for payment of CAR T-cell therapies. Response: We appreciate all the commenters' input and the additional detail regarding whether KYMRIAH and YESCARTA are substantially similar to each other and existing technologies. After consideration of the public comments we received, although we recognize the technologies are not completely the same in terms of their manufacturing process, co-stimulatory domains, and clinical profiles, we and also as the commenters expressed, are not convinced that these differences result in the use of a different mechanism of action and, therefore, infer that the two technologies' mechanisms of action are the same. Furthermore, we believe that KYMRIAH and YESCARTA are substantially similar to one another because potential cases representing patients who may be eligible for treatment using KYMRIAH and YESCARTA would group to the same MS-DRGs (because the same ICD-10- CM diagnosis codes and ICD-10-PCS procedures codes are used to report treatment using either KYMRIAH or YESCARTA). We also believe, as we and other commenters describe throughout this section, that these technologies are intended to treat the same or similar disease in the same or similar patient population--patients with r/r DLBCL who are ineligible for, or who have failed ASCT, and are purposed to achieve the same therapeutic outcome--ORR, CR, OS using the same or similar mechanism of action using genetically modified autologous T-cell immunotherapies. The respective CAR T-cells transmit a signal to promote T-cell expansion, activation, and ultimately cancer cell elimination to produce a targeted cellular therapy that may persist in the body even after the malignancy is eradicated. We also believe that KYMRIAH and YESCARTA are not substantially similar to any other existing technologies because, as both applicants asserted in their FY 2019 new technology add-on payment applications and as stated by the other commenters, the technologies do not use the same or similar mechanism of action to achieve a therapeutic outcome as any other existing drug or therapy assigned to the same or different MS-DRG and represent the only FDA-approved technologies for this treatment population. With regard to the commenter that indicated pricing of both products varies based on the patient population, and encouraged CMS to recognize this discrepancy when determining approval of new technology add-on payment and establishing adequate payments rates, we note that the applicants for both, KYMRIAH and YESCARTA, estimate that the average cost for an administered dose of KYMRIAH or YESCARTA is $373,000. We refer readers to the end of this discussion for complete details on the pricing of KYMRIAH and YESCARTA. With respect to CMS' policy for evaluating substantially similar technologies, we believe our current policy is consistent with the authority and criteria in section 1886(d)(5)(K) of the Act. We note that CMS is authorized by the Act to develop criteria for the purposes of evaluating new technology add-on payment applications. For the purposes of new technology add-on payments, when technologies are substantially similar to each other, we believe it is appropriate to evaluate both technologies as one application for new technology add-on payments under the IPPS, for the reasons we discussed above and consistent with our evaluation of substantially similar technologies in prior rulemaking (82 FR 38120). Finally, we note that for FY 2019, there is no payment impact regarding the determination that the two technologies are substantially similar to each other because the cost of the technologies is the same. However, we welcome additional comments in future rulemaking regarding whether KYMRIAH and YESCARTA are substantially similar and intend to revisit this issue in next year's proposed rule. As we stated in the proposed rule and above, each applicant submitted separate analysis regarding the cost criterion for each of their products, and both applicants maintained that their product meets the cost criterion. We summarize each analysis below. With regard to the cost criterion, the applicant for KYMRIAH searched the FY 2016 MedPAR claims data file to identify potential cases representing patients who may be eligible for treatment using KYMRIAH. The applicant identified claims that reported an ICD-10-CM diagnosis code of: C83.30 (DLBCL, unspecified site); C83.31 (DLBCL, lymph nodes of head, face and neck); C83.32 (DLBCL, intrathoracic lymph nodes); C83.33 (DLBCL, intra-abdominal lymph nodes); C83.34 (DLBCL, lymph nodes of axilla and upper limb); C83.35 (DLBCL, lymph nodes of inquinal region and lower limb); C83.36 (DLBCL, intrapelvic lymph nodes); C83.37 (DLBCL, spleen); C83.38 (DLBCL, lymph nodes of multiple sites); or C83.39 (DLBCL, extranodal and solid organ sites). The applicant also identified potential cases where patients received chemotherapy using two encounter codes, Z51.11 (Antineoplastic chemotherapy) and Z51.12 (Antineoplastic immunotherapy), in conjunction with DLBCL diagnosis codes. Applying the parameters above, the applicant for KYMRIAH identified a total of 22,589 DLBCL potential cases that mapped to 437 MS-DRGs. The applicant chose the top 20 MS-DRGs which made up a total of 15,451 potential cases at 68 percent of total cases. Of the 22,589 total DLBCL potential cases, the applicant also provided a breakdown of DLBCL potential cases where chemotherapy was used, and DLBCL potential cases where chemotherapy was not used. Of the 6,501 DLBCL potential cases where chemotherapy was used, MS-DRGs 846 and 847 accounted for 6,181 (95 percent) of the 6,501 cases. Of the 16,088 DLBCL potential cases where chemotherapy was not used, the applicant chose the top 20 MS-DRGs which made up a total of 9,333 potential cases at 58 percent of total cases. The applicant believed the distribution of patients that may be eligible for treatment using KYMRIAH will include a wide variety of MS- DRGs. As such, the applicant conducted an analysis of three scenarios: potential DLBCL cases, potential DLBCL cases with chemotherapy, and potential DLBCL cases without chemotherapy. The applicant removed reported historic charges that would be avoided through the use of KYMRIAH. Next, the applicant removed 50 percent of the chemotherapy pharmacy charges that would not be required for patients that may be eligible to receive treatment using KYMRIAH. The applicant standardized the charges and then applied an inflation factor of 1.09357, which is the 2-year inflation factor in the FY 2018 IPPS/LTCH PPS final rule (82 FR 38527), to update the charges from FY 2016 to FY 2018. The applicant did not add charges for KYMRIAH to its analysis. However, the applicant provided a cost analysis related to the three categories of claims data it previously researched (that is, potential DLBCL cases, potential DLBCL cases with chemotherapy, and potential DLBCL cases without chemotherapy). The applicant's analysis showed the inflated average case-weighted standardized charge per case for [[Page 41292]] potential DLBCL cases, potential DLBCL cases with chemotherapy, and potential DLBCL cases without chemotherapy was $63,271, $39,723, and $72,781, respectively. The average case-weighted threshold amount for potential DLBCL cases, potential DLBCL cases with chemotherapy, and potential DLBCL cases without chemotherapy was $58,278, $48,190, and $62,355 respectively. While the inflated average case-weighted standardized charge per case ($39,723) is lower than the average case- weighted threshold amount ($48,190) for potential DLBCL cases with chemotherapy, the applicant expected the cost of KYMRIAH to be higher than the new technology add-on payment threshold amount for all three cohorts. Therefore, the applicant maintained that it met the cost criterion. We noted in the proposed rule that, as discussed in section II.F.2.d. of the preamble of the proposed rule, we proposed to assign the ICD-10-PCS procedure codes that describe procedures involving the utilization of these CAR T-cell therapy drugs and cases representing patients receiving treatment involving CAR T-cell therapy procedures to Pre-MDC MS-DRG 016 for FY 2019. Therefore, in addition to the analysis above, we compared the inflated average case-weighted standardized charge per case from all three cohorts above to the average case- weighted threshold amount for MS-DRG 016. The average case-weighted threshold amount for MS-DRG 016 from Table 10 in the FY 2018 IPPS/LTCH PPS final rule is $161,058. Although the inflated average case-weighted standardized charge per case for all three cohorts ($63,271, $39,723, and $72,781) is lower than the average case-weighted threshold amount for MS-DRG 016, we noted that similar to above, the applicant expected the cost of KYMRIAH to be higher than the new technology add-on payment threshold amount for MS-DRG 016. Therefore, it appeared that KYMRIAH would meet the cost criterion under this scenario as well. We stated in the proposed rule that we appreciated the applicant's analysis. However, we noted that the applicant did not provide information regarding which specific historic charges were removed in conducting its cost analysis. Nonetheless, we stated that we believed that even if historic charges were identified and removed, the applicant would meet the cost criterion because, as indicated, the applicant expected the cost of KYMRIAH to be higher than the new technology add-on payment threshold amounts listed earlier. We invited public comments on whether KYMRIAH meets the cost criterion. Comment: Commenters agreed with CMS that KYMRIAH meets the cost criterion for new technology add-on payments based on the analysis above. The commenters noted that more recent information indicates that the cost of the drug alone is more than twice the estimated new technology add-on payment MS-DRG threshold amount. Response: We appreciate the commenters' input and note that, since the publication of the proposed rule, CMS has received supplemental information that the cost for each administration of KYMRIAH is $373,000. After consideration of the public comments we received, we agree that KYMRIAH meets the cost criterion. With regard to the cost criterion in reference to YESCARTA, the applicant conducted the following analysis. The applicant examined FY 2016 MedPAR claims data restricted to patients discharged in FY 2016. The applicant included potential cases reporting an ICD-10 diagnosis code of C83.38. Noting that only MS-DRGs 820 (Lymphoma and Leukemia with Major O.R. Procedure with MCC), 821 (Lymphoma and Leukemia with Major O.R. Procedure with CC), 823 and 824 (Lymphoma and Non-Acute Leukemia with Other O.R. Procedure with MCC, with CC, respectively), 825 (Lymphoma and Non Acute Leukemia with Other O.R Procedure without CC/MCC), and 840, 841 and 842 (Lymphoma and Non-Acute Leukemia with MCC, with CC and without CC/MCC, respectively) consisted of 10 or more cases, the applicant limited its analysis to these 8 MS-DRGs. The applicant identified 827 potential cases across these MS-DRGs. The average case-weighted unstandardized charge per case was $126,978. The applicant standardized charges using FY 2016 standardization factors and applied an inflation factor of 1.09357 from the FY 2018 IPPS/LTCH PPS final rule (82 FR 38527). The applicant for YESCARTA did not include the cost of its technology in its analysis. Included in the average case-weighted standardized charge per case were charges for the current treatment components. Therefore, the applicant for YESCARTA removed 20 percent of radiology charges to account for chemotherapy, and calculated the adjusted average case- weighted standardized charge per case by subtracting these charges from the standardized charge per case. Based on the distribution of potential cases within the eight MS-DRGs, the applicant case-weighted the final inflated average case-weighted standardized charge per case. This resulted in an inflated average case-weighted standardized charge per case of $118,575. Using the FY 2018 IPPS Table 10 thresholds, the average case-weighted threshold amount was $72,858. Even without considering the cost of its technology, the applicant maintained that because the inflated average case-weighted standardized charge per case exceeded the average case-weighted threshold amount, the technology met the cost criterion. We noted in the proposed rule that, as discussed in section II.F.2.d. of the preamble of the proposed rule, we proposed to assign the ICD-10-PCS procedure codes that describe procedures involving the utilization of these CAR T-cell therapy drugs and cases representing patients receiving treatment involving CAR T-cell therapy procedures to Pre-MDC MS-DRG 016 for FY 2019. Therefore, in addition to the analysis above, we compared the inflated average case-weighted standardized charge per case ($118,575) to the average case-weighted threshold amount for MS-DRG 016. The average case-weighted threshold amount for MS-DRG 016 from Table 10 in the FY 2018 IPPS/LTCH PPS final rule is $161,058. Although the inflated average case-weighted standardized charge per case is lower than the average case-weighted threshold amount for MS-DRG 016, we noted that the applicant expected the cost of YESCARTA to be higher than the new technology add-on payment threshold amount for MS-DRG 016. Therefore, we stated that it appeared that YESCARTA would meet the cost criterion under this scenario as well. We invited public comments on whether YESCARTA technology meets the cost criterion. Comment: Commenters agreed with CMS that YESCARTA meets the cost criterion for new technology add-on payments based on the analysis above. The commenters noted that more recent information indicates the cost of the drug alone is more than twice the estimated new technology add-on payment MS-DRG threshold amount. Response: We appreciate the commenters' input and note that, since the publication of the proposed rule, CMS has received supplemental information that the cost for each administration of YESCARTA is $373,000. After consideration of the public comments we received, we agree that YESCARTA meets the cost criterion. [[Page 41293]] With regard to substantial clinical improvement for KYMRIAH, the applicant asserted that several aspects of the treatment represent a substantial clinical improvement over existing technologies. The applicant believed that KYMRIAH allows access for a treatment option for those patients who are unable to receive standard-of-care treatment. The applicant stated in its application that there are no currently FDA-approved treatment options for patients with r/r DLBCL who are ineligible for or who have failed ASCT. Additionally, the applicant maintained that KYMRIAH significantly improves clinical outcomes, including ORR, CR, OS, and durability of response, and allows for a manageable safety profile. The applicant asserted that, when compared to the historical control data (SCHOLAR-1) and the currently available treatment options, it is clear that KYMRIAH significantly improves clinical outcomes for patients with r/r DLBCL who are not eligible for ASCT. The applicant conveyed that, given that the patient population has no other available treatment options and an expected very short lifespan without therapy, there are no randomized controlled trials of the use of KYMRIAH in patients with r/r DLBCL and, therefore, efficacy assessments must be made in comparison to historical control data. The SCHOLAR-1 study is the most comprehensive evaluation of the outcome of patients with refractory DLBCL. SCHOLAR-1 includes patients from two large randomized controlled trials (Lymphoma Academic Research Organization-CORAL and Canadian Cancer Trials Group LY.12) and two clinical databases (MD Anderson Cancer Center and University of Iowa/ Mayo Clinic Lymphoma Specialized Program of Research Excellence).\35\ --------------------------------------------------------------------------- \35\ Crump, M., Neelapu, S.S., Farooq, U., et al., ``Outcomes in refractory diffuse large B-cell lymphoma: Results from the international SCHOLAR-1 study,'' Blood, Published online: August 3, 2017, doi: 10.1182/blood-2017-03-769620. --------------------------------------------------------------------------- The applicant for KYMRIAH conveyed that the PARMA study established high-dose chemotherapy and ASCT as the standard treatment for patients with r/r DLBCL.\36\ However, according to the applicant, many patients with r/r DLBCL are ineligible for ASCT because of medical frailty. Patients who are ineligible for ASCT because of medical frailty would also be adversely affected by high-dose chemotherapy regimens.\37\ Lowering the toxicity of chemotherapy regimens becomes the only treatment option, leaving patients with little potential for therapeutic outcomes. According to the applicant, the lack of efficacy of these aforementioned salvage regimens was demonstrated in nine studies evaluating combined chemotherapeutic regimens in patients who were either refractory to first-line or first salvage. Chemotherapy response rates ranged from 0 percent to 23 percent with OS less than 10 months in all studies.\38\ For patients who do not respond to combined therapy regimens, the National Comprehensive Cancer Network (NCCN) offers only clinical trials or palliative care as therapeutic options.\39\ --------------------------------------------------------------------------- \36\ Philip, T., Guglielmi, C., Hagenbeek, A., et al., ``Autologous bone marrow transplantation as compared with salvage chemotherapy in relapses of chemotherapy-sensitive non-Hodgkin's lymphoma,'' N Engl J Med, 1995, vol. 333(23), pp. 1540-1545. \37\ Friedberg, J.W., ``Relapsed/refractory diffuse large B-cell lymphoma,'' Hematology AM Soc Hematol Educ Program, 2011, vol.

However, none induced a CR rate higher than 20 percent or showed a median duration of response longer than 1 year.\41\ --------------------------------------------------------------------------- \40\ Klyuchnikov, E., Bacher, U., Kroll, T., et al., ``Allogeneic hematopoietic cell transplantation for diffuse large B cell lymphoma: Who, when and how?,'' Bone Marrow Transplant, 2014, vol. 49(1), pp. 1-7. \41\ Ibid. --------------------------------------------------------------------------- According to the applicant, although controversial, allogeneic stem cell transplantation (allo-SCT) has been proposed for patients who have been diagnosed with r/r disease. It is hypothesized that the malignant cell will be less able to escape the immune targeting of allogenic T- cells--known as the graft-vs-lymphoma effect.42 43 The use of allo-SCT is limited in patients who are not eligible for ASCT because of the high rate of morbidity and mortality. This medically frail population is generally excluded from participation. The population most impacted by this is the elderly, who are often excluded based on age alone. In seven studies evaluating allo-SCT in patients with r/r DLBCL, the median age at transplant was 43 years old to 52 years old, considerably lower than the median age of patients with DLBCL of 64 years old. Only two studies included any patients over 66 years old. In these studies, allo-SCT provided OS rates ranging from 18 percent to 52 percent at 3 to 5 years, but was accompanied by treatment-related mortality rates ranging from 23 percent to 56 percent.\44\ According to the applicant, this toxicity and efficacy profile of allo-SCT substantially limits its use, especially in patients 65 years old and older. Given the high unmet medical need, the applicant maintained that KYMRIAH represents a substantial clinical improvement by offering a treatment option for a patient population unresponsive to, or ineligible for, currently available treatments. --------------------------------------------------------------------------- \42\ Ibid. \43\ Maude, S.L., Teachey, D.T., Porter, D.L., Grupp, S.A., ``CD19-targeted chimeric antigen receptor T-cell therapy for acute lymphoblastic leukemia,'' Blood, 2015, vol. 125(26), pp. 4017-4023. \44\ Klyuchnikov, E., Bacher, U., Kroll, T., et al., ``Allogeneic hematopoietic cell transplantation for diffuse large B cell lymphoma: Who, when and how?,'' Bone Marrow Transplant, 2014, vol. 49(1), pp. 1-7. --------------------------------------------------------------------------- To express how KYMRIAH has improved clinical outcomes, including ORR, CR rate, OS, and durability of response, the applicant referenced clinical trials in which KYMRIAH was tested. Study 1 was a single-arm, open-label, multi-site, global Phase II study to determine the safety and efficacy of tisagenlecleucel in patients with R/R DLBCL (CCTL019C2201/CT02445248/`JULIET' study).45 46 47 Key inclusion criteria included patients who were 18 years old and older, patients with refractory to at least two lines of chemotherapy and either relapsed post ASCT or who were ineligible for ASCT, measurable disease at the time of infusion, and adequate organ and bone marrow function. The study was conducted in three phases. In the screening phase patient eligibility was [[Page 41294]] assessed and patient cells collected for product manufacture. Patients were also able to receive bridging, cytotoxic chemotherapy during this time. In the pre-treatment phase patients underwent a restaging of disease followed by lymphodepleting chemotherapy with fludarabine 25mg/ m2 x 3 and cyclophosphamide 250mg/m2/d x 3 or bendamustine 90mg/m2/d x 2 days. The treatment and follow-up phase began 2 to 14 days after lymphodepleting chemotherapy, when the patient received a single infusion of tisagenlecleucel with a target dose of 5 x 108 CTL019 transduced viable cells. The primary objective was to assess the efficacy of tisagenlecleucel, as measured by the best overall response (BOR), which was defined as CR or partial response (PR). It was assessed on the Chesson 2007 response criteria amended by Novartis Pharmaceutical Corporation as confirmed by an Independent Review Committee (IRC). One hundred forty-seven patients were enrolled, and 99 of them were infused with tisagenlecleucel. Forty-three patients discontinued prior to infusion (9 due to inability to manufacture and 34 due to patient-related issues).\48\ The median age of treated patients was 56 years old with a range of 24 to 75; 20 percent were older than 65 years old. Patients had received 2 to 7 prior lines of therapy, with 60 percent receiving 3 or more therapies, and 51 percent having previously undergone ASCT. A primary analysis was performed on 81 patients infused and followed for more than or at least 3 months. In this primary analysis, the BOR was 53 percent; the study met its primary objective based on statistical analysis (that is, testing whether BOR was greater than 20 percent, a clinically relevant threshold chosen based on the response to chemotherapy in a patient with r/r DLBCL). Forty-three percent (43 percent) of evaluated patients reached a CR, and 14 percent reached a PR. ORR evaluated at 3 months was 38 percent with a distribution of 32 percent CR and 6 percent PR. All patients in CR at 3 months continued to be in CR. ORR was similar across subgroups including 64.7 percent response in patients who were older than 65 years old, 61.1 percent response in patients with Grade III/IV disease at the time of enrollment, 58.3 percent response in patients with Activated B-cell, 52.4 percent response in patients with Germinal Center B-cell subtype, and 60 percent response in patients with double and triple hit lymphoma. Durability of response was assessed based on relapse free survival (RFS), which was estimated at 74 percent at 6 months. --------------------------------------------------------------------------- \45\ Data on file, Oncology clinical trial protocol CCTL019C2201: ``A Phase II, single-arm, multi-center trial to determine the efficacy and safety of CTL019 in adult patients with relapsed or refractory diffuse large Bcell lymphoma (DLBCL),'' Novartis Pharmaceutical Corp, 2015. \46\ Schuster, S.J., Bishop, M.R., Tam, C., et al., ``Global trial of the efficacy and safety of CTL019 in adult patients with relapsed or refractory diffuse large B-cell lymphoma: An interim analysis,'' Presented at: 22nd Congress of the European Hematology Association, June 22-25, 2017, Madrid, Spain. \47\ ClinicalTrials.gov, ``Study of efficacy and safety of CTL019 in adult DLBCL patients (JULIET).''Available at: https://clinicaltrials.gov/ct2/show/NCT02445248. \48\ Schuster, S.J., Bishop, M.R., Tam, C., et al., ``Global trial of the efficacy and safety of CTL019 in adult patients with relapsed or refractory diffuse large B-cell lymphoma: an interim analysis,'' Presented at: 22nd Congress of the European Hematology Association, June 22-25, 2017, Madrid, Spain. --------------------------------------------------------------------------- The applicant for KYMRIAH reported that Study 2 was a supportive Phase IIa single institution study of adults who were diagnosed with advanced CD19+ NHL conducted at the University of Pennsylvania.49 50 Tisagenlecleucel cells were produced at the University of Pennsylvania using the same genetic construct and a similar manufacturing technique as employed in Study 1. Key inclusion criteria included patients who were at least 18 years old, patients with CD19+ lymphoma with no available curative options, and measurable disease at the time of enrollment. Tisagenlecleucel was delivered in a single infusion 1 to 4 days after restaging and lymphodepleting chemotherapy. The median tisagenlecleucel cell dose was 5.0 x 108 transduced cells. The study enrolled 38 patients; of these, 21 were diagnosed with DLBCL and 13 received treatment involving KYMRIAH. Patients ranged in age from 25 to 77 years old, and had a median of 4 prior therapies. Thirty-seven percent had undergone ASCT and 63 percent were diagnosed with Grade III/IV disease. ORR at 3 months was 54 percent. Progression free survival was 43 percent at a median follow-up of 11.7 months. Safety and efficacy results are similar to those of the multi-center study. --------------------------------------------------------------------------- \49\ ClinicalTrials.gov, ``Phase IIa study of redirected autologous T-cells engineered to contain anti-CD19 attached to TCRz and 4-signaling domains in patients with chemotherapy relapsed or refractory CD19+ lymphomas,'' Available at: https://clinicaltrials.gov/ct2/show/NCT02030834. \50\ Schuster, S.J., Svoboda, J., Nasta, S.D., et al., ``Sustained remissions following chimeric antigen receptor modified T-cells directed against CD-19 (CTL019) in patients with relapsed or refractory CD19+ lymphomas,'' Presented at: 57th Annual Meeting of the American Society of Hematology, December 6, 2015, Orlando, FL. --------------------------------------------------------------------------- The applicant for KYMRIAH reported that Study 3 was a supportive, patient-level meta-analysis of historical outcomes in patients who were diagnosed with refractory DLBCL (SCHOLAR-1).\51\ This study included a pooled data analysis of two Phase III clinical trials (Lymphoma Academic Research Organization-CORAL and Canadian Cancer Trials Group LY.12) and two observational cohorts (MD Anderson Cancer Center and University of Iowa/Mayo Clinic Lymphoma Specialized Program of Research Excellence). Refractory disease was defined as progressive disease or stable disease as best response to chemotherapy (received more than or at least 4 cycles of first-line therapy or 2 cycles of later-line therapy, respectively) or relapse in less than or at 12 months post- ASCT. Of 861 abstracted records, 636 were included based on these criteria. All patients from each data source who met criteria for diagnosis of refractory DLBCL, including TFL and PMBCL, who went on to receive subsequent therapy were considered for analysis. Patients who were diagnosed with TFL and PMBCL were included because they are histologically similar and clinically treated as large cell lymphoma. Response rates were similar across the 4 datasets, ranging from 20 percent to 31 percent, with a pooled response rate of 26 percent. CR rates ranged from 2 percent to 15 percent, with a pooled CR rate of 7 percent. Subgroup analyses including patients with primary refractory, refractory to second or later-line therapy, and relapse in less than 12 months post-ASCT revealed response rates similar to the pooled analysis, with worst outcomes in the primary refractory group (20 percent). OS from the commencement of therapy was 6.3 months and was similar across subgroup analyses. Achieving a CR after last salvage chemotherapy predicted a longer OS of 14.9 months compared to 4.6 months in nonresponders. Patients who had not undergone ASCT had an OS of 5.1 months with a 2 year OS rate of 11 percent. --------------------------------------------------------------------------- \51\ Crump, M., Neelapu, S.S., Farooq, U., et al., ``Outcomes in refractory diffuse large B-cell lymphoma: Results from the international SCHOLAR-1 study,'' Blood, Published online: August 3, 2017, doi: 10.1182/blood-2017-03-769620. --------------------------------------------------------------------------- The applicant asserted that KYMRIAH provides a manageable safety profile when treatment is performed by trained medical personnel and, as opposed to ASCT, KYMRIAH mitigates the need for high-dose chemotherapy to induce response prior to infusion. Adverse events were most common in the 8 weeks following infusion and were manageable by a trained staff. Cytokine Relapse Syndrome (CRS) occurred in 58 percent of patients with 23 percent having Grade III or IV events as graded on the University of Pennsylvania grading system.52 53 Median time to [[Page 41295]] onset of CRS was 3 days and median duration was 7 days with a range of 2 to 30 days. Twenty-four percent of the patients required ICU admission. CRS was managed with supportive care in most patients. However, 16 percent required anti-cytokine therapy including tocilizumab (15 percent) and corticosteroids (11 percent). Other adverse events of special interest include infection in 34 percent (20 percent Grade III or IV) of patients, cytopenias not resolved by day 28 in 36 percent (27 percent Grade III or IV) of patients, neurologic events in 21 percent (12 percent Grade III or IV) of patients, febrile neutropenia in 13 percent (13 percent Grade III or IV) of patients, and tumor lysis syndrome 1 percent (1 percent Grade III). No deaths were attributed to tisagenlecleucel including no fatal cases of CRS or neurologic events. No cerebral edema was observed.\54\ Study 2 safety results were consistent to those of Study 1.\55\ --------------------------------------------------------------------------- \52\ ClinicalTrials.gov, ``Phase IIa study of redirected autologous T-cells engineered to contain anti-CD19 attached to TCRz and 4-signaling domains in patients with chemotherapy relapsed or refractory CD19+ lymphomas.''

Furthermore, the discontinue rate of the JULIET trial was high. Of 147 patients enrolled for infusion involving KYMRIAH, 43 discontinued prior to infusion (9 discontinued due to inability to manufacture, and 34 discontinued due to patient-related issues). Finally, the rate of patients who experienced a diagnosis of CRS was high, 58 percent.\56\ --------------------------------------------------------------------------- \56\ Schuster, S.J., Bishop, M.R., Tam, C., et al., ``Global trial of the efficacy and safety of CTL019 in adult patients with relapsed or refractory diffuse large B-cell lymphoma: an interim analysis,'' Presented at: 22nd Congress of the European Hematology Association, June 22-25, 2017, Madrid, Spain. --------------------------------------------------------------------------- The applicant for YESCARTA stated that YESCARTA represents a substantial clinical improvement over existing technologies when used in the treatment of patients with aggressive B-cell NHL. The applicant asserted that YESCARTA can benefit the patient population with the highest unmet need, patients with r/r disease after failure of first- line or second-line therapy, and patients who have failed or who are ineligible for ASCT. These patients, otherwise, have adverse outcomes as demonstrated by historical control data. Regarding clinical data for YESCARTA, the applicant stated that historical control data was the only ethical and feasible comparison information for these patients with chemorefractory, aggressive NHL who have no other available treatment options and who are expected to have a very short lifespan without therapy. According to the applicant, based on meta-analysis of outcomes in patients with chemorefractory DLBCL, there are no curative options for patients with aggressive B- cell NHL, regardless of refractory subgroup, line of therapy, and disease stage with their median OS being 6.6 months.\57\ --------------------------------------------------------------------------- \57\ Seshardi, T., et al., ``Salvage therapy for relapsed/ refractory diffuse large B-cell lymphoma,'' Biol Blood Marrow Transplant, 2008 Mar, vol. 14(3), pp. 259-67. --------------------------------------------------------------------------- In the applicant's FY 2018 new technology add-on payment application for the KTE-C19 technology, which was discussed in the FY 2018 IPPS/LTCH PPS proposed rule (82 FR 19889), the applicant cited ongoing clinical trials. The applicant provided updated data related to these ongoing clinical trials as part of its FY 2019 application for YESCARTA.58 59 60 The updated analysis of the pivotal Study 1 (ZUMA-1, KTE-C19-101), Phase I and II occurred when patients had been followed for 12 months after infusion of YESCARTA. Study 1 is a Phase I-II multi-center, open-label study evaluating the safety and efficacy of the use of YESCARTA in patients with aggressive refractory NHL. The trial consists of two distinct phases designed as Phase I (n=7) and Phase II (n=101). Phase II is a multi-cohort open-label study evaluating the efficacy of YESCARTA.\61\ The applicant noted that, as of the analysis cutoff date for the interim analysis, the results of Study 1 demonstrated rapid and substantial improvement in objective, or ORR. After 6 and 12 months, the ORR was 82 and 83 percent, respectively. Consistent response rates were observed in both Study 1, Cohort 1 (DLBCL; n=77) and Cohort 2 (PMBCL or TFL; n=24) and across covariates including disease stage, age, IPI scores, CD-19 status, and refractory disease subset. In the updated analysis, results were consistent across age groups. In this analysis, 39 percent of patients younger than 65 years old were in ongoing response, and 50 percent of patients at least 65 years old or older were in ongoing response. Similarly, the survival rate at 12 months was 57 percent among patients younger than 65 years old and 71 percent among patients at least 65 years old or older versus historical control of 26 percent. The applicant further stated that evidence of substantial clinical improvement regarding the efficacy of YESCARTA for the treatment of patients with chemorefractory, aggressive B-cell NHL is supported by the CR of YESCARTA in Study 1, Phase II (54 percent) versus the historical control (7 percent).62 63 64 65 The applicant noted that CR rates were observed in both Study 1, Cohort 1. The applicant reported that, in the updated analysis, results were in ongoing response (46 percent of patients at least 65 years old or older were in ongoing response). Similarly, the survival rate at 12 months was 57 percent among patients younger than 65 years old and 71 percent among patients at least 65 years old or older.66 67 68 69 The applicant also [[Page 41296]] provided the following tables to depict data to support substantial clinical improvement (we refer readers to the two tables below). --------------------------------------------------------------------------- \58\ Locke, F.L., et al., ``Ongoing complete remissions in Phase 1 of ZUMA-1: a phase I-II multicenter study evaluating the safety and efficacy of KTE-C19 (anti-CD19 CAR T cells) in patients with refractory aggressive B-cell non-Hodgkin lymphoma (NHL),'' Oral presentation (abstract 10480) presented at European Society for Medical Oncology (ESMO), October 2016. \59\ Locke, F.L., et al., ``Primary results from ZUMA-1: a pivotal trial of axicabtagene ciloretroleucel (axi-cel; KTE-C19) in patients with refractory aggressive non-Hodgkins lymphoma (NHL),'' Oral presentation, American Association of Cancer Research (AACR). \60\ Locke, F.L., et al., ``Phase I results of ZUMA-1: a multicenter study of KTE-C19 anti-CD19 CAR T cell therapy in refractory aggressive lymphoma,'' Mol Ther, vol. 25, No 1, January 2017. \61\ Neelapu, S.S., Locke, F.L., et al., 2016, ``KTE-C19 (anti- CD19 CAR T cells) induces complete remissions in patients with refractory diffuse large B-cell lymphoma (DLBCL): results from the pivotal Phase II ZUMA-1,'' Abstract presented at American Society of Hematology (ASH) 58th Annual Meeting, December 2016. \62\ Locke, F.L., et al., ``Ongoing complete remissions in Phase I of ZUMA-1: a phase I-II multicenter study evaluating the safety and efficacy of KTE-C19 (anti-CD19 CAR T cells) in patients with refractory aggressive B-cell non-Hodgkin lymphoma (NHL),'' Oral presentation (abstract 10480) presented at European Society for Medical Oncology (ESMO), October 2016. \63\ Locke, F.L., et al., ``Primary results from ZUMA-1: a pivotal trial of axicabtagene ciloretroleucel (axi-cel; KTE-C19) in patients with refractory aggressive non-Hodgkins lymphoma (NHL),'' Oral presentation, American Association of Cancer Research (AACR). \64\ Locke, F.L., et al., ``Phase I results of ZUMA-1: a multicenter study of KTE-C19 anti-CD19 CAR T cell therapy in refractory aggressive lymphoma,'' Mol Ther, vol. 25, No 1, January 2017. \65\ Crump, et al., 2017, ``Outcomes in refractory diffuse large B-cell lymphoma: Results from the international SCHOLAR-1 study,'' Blood, vol. 0, 2017, pp. blood-2017-03-769620v1. \66\ Locke, F.L., et al., ``Ongoing complete remissions in Phase I of ZUMA-1: a phase I-II multicenter study evaluating the safety and efficacy of KTE-C19 (anti-CD19 CAR T cells) in patients with refractory aggressive B-cell non-Hodgkin lymphoma (NHL),'' Oral presentation (abstract 10480) presented at European Society for Medical Oncology (ESMO), October 2016. \67\ Locke, F.L., et al., ``Primary results from ZUMA-1: a pivotal trial of axicabtagene ciloretroleucel (axi-cel; KTE-C19) in patients with refractory aggressive non-Hodgkins lymphoma (NHL),'' Oral presentation, American Association of Cancer Research (AACR). \68\ Locke, F.L., et al., ``Phase I results of ZUMA-1: a multicenter study of KTE-C19 anti-CD19 CAR T cell therapy in refractory aggressive lymphoma,'' Mol Ther, vol. 25, No 1, January 2017. \69\ Crump, et al., ``Outcomes in refractory diffuse large B- cell lymphoma: results from the international SCHOLAR-1 study,'' Blood, vol. 0, 2017, pp. blood-2017-03-769620v1.

According to the applicant, the clinical trial protocol stipulated that patients were infused with YESCARTA in the hospital inpatient setting and were monitored in the inpatient setting for at least 7 days for early identification and treatment involving YESCARTA- related toxicities, which primarily included CRS diagnoses and neurotoxicities. The applicant noted that the interim analysis showed the length of stay following infusion of YESCARTA was a median of 15 days. Ninety-three percent of patients experienced CRS diagnoses, 13 percent of whom experienced Grade III or higher (severe, life threatening or fatal) CRS diagnoses. The median time to onset of CRS diagnosis was 2 days (range 1 to 12 days) and the median time to resolution was 8 days. Ninety-eight percent of patients recovered from CRS diagnosis. Neurologic events occurred in 64 percent of patients, 28 percent of whom experienced Grade III or higher (severe or life threatening) events. The median time to onset of neurologic events was 5 days (range 1 to 17 days). The median time to resolution was 17 days. Nearly all patients recovered from neurologic events. The medications most often used to treat these complications included growth factors, blood products, anti-infectives, steroids, tocilizumab, and vasopressors. Two patients died from YESCARTA-related adverse events (hemophagocytic lymphohistiocytosis and cardiac arrest in the hospital setting as a result of CRS diagnoses). According to the applicant, there were no clinically important differences in adverse event rates across age groups (younger than 65 years old; 65 years old or older), including CRS diagnoses and neurotoxicity.74 75 --------------------------------------------------------------------------- \74\ Locke, F.L., et al., ``Ongoing complete remissions in Phase I of ZUMA-1: a phase I-II multicenter study evaluating the safety and efficacy of KTE-C19 (anti-CD19 CAR T cells) in patients with refractory aggressive B-cell non-Hodgkin lymphoma (NHL),'' Oral presentation (abstract 10480) presented at European Society for Medical Oncology (ESMO), October 2016. \75\ Locke, F.L., et al., ``Primary results from ZUMA-1: a pivotal trial of axicabtagene ciloretroleucel (axi-cel; KTE-C19) in patients with refractory aggressive non-Hodgkins lymphoma (NHL),'' Oral presentation, American Association of Cancer Research (AACR). --------------------------------------------------------------------------- The applicant for YESCARTA provided information regarding a safety expansion cohort, Study 1 Phase II Safety Expansion Cohort 3 that was created and carried out in 2017. According to the applicant, this Safety Expansion Cohort investigated measures to mitigate the incidence and/or severity of anti-CD-19 CAR T therapy and evaluated an adverse event mitigation strategy by prophylactically using levetiracetam (Keppra), an anticonvulsant, and tocilizumab, an IL-6 receptor inhibitor. Of the 30 patients treated, 2 patients experienced Grade III CRS diagnoses; 1 of the 2 patients recovered. In late April 2017, the other patient also experienced multi-organ failure and a neurologic event that subsequently progressed to a fatal Grade V cerebral edema that was deemed related to YESCARTA treatment. This case of cerebral edema was observed in a 21 year-old male with refractory, rapidly progressive, symptomatic, stage IVB PMBCL. Analysis of the baseline serum and cerebrospinal fluid (CSF) obtained prior to any study treatment demonstrated high cytokine and [[Page 41297]] chemokine levels. According to the applicant, this suggests a significant preexisting underlying inflammatory process, both systemically and within the central nervous system. Rapidly progressing disease, recent mediastinal XRT (external beam radiation therapy) and/ or CMV (cytomegalovirus) reactivation may have contributed to the pre- existing state. There were no prior cases of cerebral edema in the 200 patients who have been treated with YESCARTA in the ZUMA clinical development program. The single patient event from the Study 1 Phase II Safety Expansion Cohort 3 was the first Grade V cerebral edema event.76 77 --------------------------------------------------------------------------- \76\ Locke, F.L., et al., ``Ongoing complete remissions in Phase I of ZUMA-1: a phase I-II multicenter study evaluating the safety and efficacy of KTE-C19 (anti-CD19 CAR T cells) in patients with refractory aggressive B-cell non-Hodgkin lymphoma (NHL),'' Oral presentation (abstract 10480) presented at European Society for Medical Oncology (ESMO), October 2016. \77\ Locke, F.L., et al., ``Primary results from ZUMA-1: a pivotal trial of axicabtagene ciloretroleucel (aci-cel; KTE-C19) in patients with refractory aggressive non-Hodgkins lymphoma (NHL),'' Oral presentation, American Association of Cancer Research (AACR). --------------------------------------------------------------------------- After reviewing the information submitted by the applicant as part of its FY 2019 new technology add-on payment application for YESCARTA, we stated in the FY 2019 IPPS/LTCH PPS proposed rule that we were concerned that it does not appear to include patient mortality data that was included as part of the applicant's FY2018 new technology add- on payment application for the KTE-C19 technology. In that application, as discussed in the FY 2018 IPPS/LTCH PPS proposed rule (82 FR 19890), the applicant provided that by an earlier cutoff date for the interim analysis of Study 1, among all KTE-C19 treated patients, 12 patients in Study 1, Phase II, including 10 from Cohort 1, and 2 from Cohort 2, died. Eight of these deaths were due to disease progression. One patient had disease progression after receiving KTE-C19 treatment and subsequently had ASCT. After ASCT, the patient died due to sepsis. Two patients (3 percent) died due to KTE-C19-related adverse events (Grade V hemophagocytic lymphohistiocytosis event and Grade V anoxic brain injury), and one died due to an adverse event deemed unrelated to treatment involving KTE-C19 (Grade V pulmonary embolism), without disease progression. We believed it would be relevant to include this information because it is related to the same treatment that is the subject of the applicant's FY 2019 new technology add-on payment application. --------------------------------------------------------------------------- \77\ Locke, F.L., et al., ``Primary results from ZUMA-1: a pivotal trial of axicabtagene ciloretroleucel (aci-cel; KTE-C19) in patients with refractory aggressive non-Hodgkins lymphoma (NHL),'' Oral presentation, American Association of Cancer Research (AACR). --------------------------------------------------------------------------- We also stated that we were concerned that there are few published results showing any survival benefits from the use of this treatment. In addition, we were concerned with the limited number of patients (n=108) that were studied after infusion involving YESCARTA T-cell immunotherapy. Finally, we indicated that we were concerned about the data related to the percentage of patients who experienced complications or toxicities related to YESCARTA treatment. According to the applicant, of the patients who participated in YESCARTA clinical trials, 93 percent developed CRS diagnoses and 64 percent experienced neurological adverse events. We invited public comments on whether KYMRIAH and YESCARTA meet the substantial clinical improvement criterion. The applicants for KYMRIAH and YESCARTA, as well as others submitted comments regarding whether KYMRIAH and YESCARTA met the substantial clinical improvement criterion. Comment: The applicant for KYMRIAH responded to CMS' concerns presented in the proposed rule regarding the JULIET trial and provided updated trial results. According to the applicant, of the 160 patients enrolled in the JULIET trial, 106 patients received treatment involving tisagenlecleucel, including 92 patients who received the product manufactured in the U.S. and were followed for at least 3 months or discontinued earlier. The applicant stated that 11 out of 160 patients (7 percent) enrolled did not receive treatment involving tisagenlecleucel due to manufacturing failure and 38 other patients did not receive treatment involving tisagenlecleucel due to patient-related issues. In response to CMS' concerns that the use of the SCHOLAR-1 study as a baseline for comparison to the JULIET trial may have skewed results because the baseline population of the SCHOLAR-1 study included patient populations diagnosed with TFL and PMBCL, the applicant for KYMRIAH stated that the JULIET trial included patients diagnosed with TFL, making this patient population similar in nature to what was included in the SCHOLAR study. The applicant also indicated that, although it is true that patients diagnosed with PMBCL were excluded from the JULIET trial, these patients only make up 2 percent of the total population of the 636 patients evaluated in the SCHOLAR-1 study; limiting the impact that these patients could have had on the observed response rates. The applicant further explained that PMBCL is a form of large cell lymphoma, which differs from DLBCL in that the patient population is often younger and healthier and patients diagnosed with PMBCL are more likely to respond to first-line therapy, therefore, relapsed and refractory (r/r) patients are rare compared to those diagnosed with DLBCL. The applicant also stated that, due to the infrequency of patients diagnosed with r/r PMBCL, research isolating this pathology for treatment effect is limited. The applicant indicated that, although some studies estimate that chemorefractory PMBCL has a lower response rate than refractory DLBCL, those studies still report ORR equivalent to what was shown in SCHOLAR and each of these studies' results show r/ r PMBCL patients having a CR rate that is equivalent or better than what was observed in the larger SCHOLAR study. The applicant believed that, given these outcomes and the small number of patients diagnosed with PMBCL in the SCHOLAR literature, it is unlikely that the results are skewed in such a way as to overestimate the comparative efficacy of KYMRIAH for patients diagnosed with r/r DLBCL. In response to CMS' concerns regarding the drop-out rate within the JULIET trial, the applicant for KYMRIAH stated that the JULIET trial was designed to reflect a paradigm of patient management that the applicant believes reflects the real-world treatment decisions of health care providers. The applicant explained that in the JULIET trial, any patient who was identified as a candidate for treatment involving KYMRIAH and could undergo apheresis was enrolled in the trial at the time of apheresis collection, then patients were allowed to undergo bridging chemotherapy during the time that they awaited a manufacturing slot assignment and during the manufacturing process. The applicant indicated that this is in contrast with protocols of other trials in which patients are not enrolled until such time as a manufacturing slot is available because patients diagnosed with r/r DLBCL have rapidly progressive disease and they often have disease which is resistant or refractory to therapy and, therefore, patients may progress during this time. The applicant further stated that the design of the JULIET trial allowed these events to be captured, whereas other study designs that do not [[Page 41298]] enroll patients until a manufacturing slot is available and assigned would not capture such events because such patients would never be enrolled in the study. The applicant explained that the median time from apheresis to infusion of 113 days is not a direct measure of manufacturing time and reflects the fact that cryopreserved apheresis allowed patients to be apheresed before trial enrollment. Additionally, the applicant stated that the point at which the patient is infused after manufacturing is at the discretion of the treating physician, based on what is appropriate for the patient. The applicant explained that the use of cryopreserved apheresis material allows physicians to maximize the timing of apheresis for the benefit of patients and to minimize the effect of preceding chemotherapy on the health of the cells, which is not accounted for in a measurement of apheresis to infusion. The applicant further stated that the clinical trial was managed differently than their commercial process. The applicant indicated that, early in the JULIET trial, capacity-limited manufacturing could have led to longer wait times compared to their current commercial (non-trial) process, where patient cells are manufactured on a first-in, first manufactured basis and, their target is a 22-day manufacturing cycle from receipt of leukapheresis material, according to Novartis's requirements, to return shipping of KYMRIAH. The applicant also responded to CMS' concern regarding the percentage of patients who experienced CRS in the JULIET trial. The applicant for KYMRIAH stated that updated results show, using the conservative University of Pennsylvania Scale, CRS occurred in 78 percent of the patients enrolled in the JULIET clinical trial. However, only 23 percent of the patients had >=Grade III CRS and no patient had Grade V CRS. The applicant further stated that patients with low grade CRS may reflect symptoms such as fever, myalgia, nausea or fatigue. The applicant noted that, in this context, the patients with >=Grade III CRS represent those with a life-threatening condition that requires interventions to support respiratory or circulatory function. The applicant indicated that CRS was manageable by a trained staff according to a specific CRS treatment algorithm and current standard- of-care for these patients includes high-dose salvage chemotherapy regimens, as well as myeloablative therapy prior to autologous stem cell transplant, both of which have aggressive toxicity profiles. However, the applicant indicated that many of the toxicities of autologous stem cell transplant are managed without the benefit of treatment algorithms and directed therapies which aid in the management of CRS. The applicant for YESCARTA responded to CMS' concern that its new technology add-on payment application did not appear to include patient mortality data that was included as part of the applicant's FY 2018 new technology add-on payment application for the KTE-C19 technology. The applicant acknowledged that the Study 1 interim analysis data included in the FY2018 new technology add-on payment application and depicted as CMS' concern was not explicitly detailed in the FY 2019 application, which focused on the primary analysis, nor in Supplement 2, which provided data from the updated analysis. The applicant confirmed that there were no new deaths from adverse events at the time of the Study 1 primary analysis (median follow-up of 6 months) or at the time of the updated analysis (median follow-up of 15.4 months). The applicant also responded to CMS' concern that there are few published results describing survival benefits from the use of YESCARTA. The applicant indicated that information to address this issue was submitted to CMS in a new technology add-on payment supplemental file. The applicant indicated that this file provided data from the updated analysis (median follow-up of 15.4 months) and references for the published manuscripts. (We note that the information the applicant provided with its public comment was also previously provided to CMS in the supplemental file mentioned above). The applicant stated that, in December 2017, the long-term follow-up of Study 1 (ZUMA-1), Phase I (n=7), and Phase II (n=101) was published in the New England Journal of Medicine and presented at ASH 2017. The applicant explained that at median 15.4 months follow-up at the time of the updated analysis data cutoff (August 11, 2017), responses were ongoing in 42 percent of the patients where median duration of response for complete response has not been reached and median overall survival has not been reached. The applicant indicated that the authors concluded these high levels of durable response confirmed that YESCARTA is highly effective and provides substantial clinical benefit for patients diagnosed with large B-cell lymphoma who otherwise have no curative options. Additionally, the applicant stated that results show (best objective response, ongoing) ORR (82 percent, 42 percent) and CR (58 percent, 40 percent) at the time of the updated analysis (15.4 months) are significantly improved over results from SCHOLAR-1 historical control of 26 percent. The applicant stated that, based on the evidence of improved benefits provided to patients with no other treatment options, this study supports the finding that YESCARTA demonstrates that it represents a substantial clinical improvement over existing treatment options. The applicant further detailed that the results from the updated analysis show: The median time to response was rapid (1.0 month; range, 0.8 to 6.0) and that the median duration of complete response has not been reached. Additionally, the applicant explained that responses to treatment, including ongoing ones, were consistent across key covariates, including in individuals 65 years of age and younger and those individuals 65 years of age and older. The applicant also indicated that the median overall survival has not been reached. However, the applicant stated that the results of the updated analysis show the overall survival rate at 18 months was 52 percent and 56 percent of patients enrolled in the study were alive at the time of the updated analysis. The applicant also indicated that results show ongoing durable remissions have been observed in patients at 24 months. The applicant for YESCARTA also responded to CMS' concern regarding the limited number of patients (n=108) that were studied after infusion involving YESCARTA T-cell immunotherapy. The applicant stated that the statistical plan for Study 1 was developed by Kite in close discussion with FDA. The applicant explained that the design of this statistical plan was developed so that the study size would be powered to show statistical significance for the primary end point: ORR. The applicant indicated that the primary analysis of Study 1, Phase II demonstrates that the primary endpoint has been met and that key secondary endpoints including Duration of Response and Overall Survival were also met. Therefore, the applicant believed that the results of the clinical data show YESCARTA has demonstrated substantial clinical improvement for patients who previously had no curative options, no standard therapy and a short expected survival. The applicant also explained that the sample size (the number of patients planned) for Study 1 was determined by the number of patients required to statistically demonstrate an improvement in the response rate with treatment involving YESCARTA and is [[Page 41299]] consistent with other single-arm oncology studies with a response rate endpoint. The applicant indicated that Study 1 had an adequate sample size to provide 90 percent power to statistically demonstrate an improvement in response rate relative to the historical control rate of 20 percent, and a historical control was the only ethical and feasible study design for these r/r large B-cell lymphoma patients who previously had no other treatment options and have a uniformly very poor outcome without therapy. The applicant stated that standard protocols, when evaluating a therapy with a profound improvement in the endpoint, usually require a smaller sample size and larger studies are required when the improvement in the endpoint is small or difficult to demonstrate. The applicant believed that, given the magnitude of improved benefit from treatment with YESCARTA, the sample size of n=108 was adequate to demonstrate efficacy and the trial was adequately sized to demonstrate a positive risk-benefit consistent with Good Clinical Practice (GCP)17 and International Conference on Harmonization (ICH) guidelines. Response: We appreciate the applicants' submission of additional information to address the concerns presented in the proposed rule. After consideration of the public comments we received, we agree that both, KYMRIAH and YESCARTA, represent a substantial clinical improvement over existing technologies because the technologies allow access for a treatment option for those patients who are unable to receive standard-of-care treatment. Additionally, there are no other currently FDA-approved treatment options for patients with r/r DLBCL who are ineligible for, or who have failed ASCT. Finally, both technologies appear to significantly improve clinical outcomes, including ORR, CR, OS, and durability of response, and allow for a manageable safety profile. In summary, we have determined that KYMRIAH and YESCARTA meet all of the criteria for approval of new technology add-on payments. Therefore, we are approving new technology add-on payments for KYMRIAH and YESCARTA for FY 2019. We expect that KYMRIAH will be administered for the treatment of adult patients (18 years old and older) diagnosed with r/r DLBCL not eligible for ASCT, and YESCARTA will be administered for the treatment of adult patients diagnosed with r/r large B-cell lymphoma after two or more lines of systemic therapy, including DLBCL not otherwise specified, primary mediastinal large B-cell, high grade B-cell lymphoma, and DLBCL arising from follicular lymphoma. Cases involving KYMRIAH and YESCARTA that are eligible for new technology add-on payments will be identified by ICD-10-PCS procedure codes XW033C3 and XW043C3. The applicants for both, KYMRIAH and YESCARTA, estimate that the average cost for an administered dose of KYMRIAH or YESCARTA is $373,000. Under Sec. 412.88(a)(2), we limit new technology add-on payments to the lesser of 50 percent of the average cost of the technology, or 50 percent of the costs in excess of the MS-DRG payment for the case. As a result, the maximum new technology add-on payment for a case involving the use of KYMRIAH or YESCARTA is $186,500 for FY 2019. We note that on May 16, 2018, CMS opened a national coverage determination (NCD) analysis on CAR T-cell therapy for Medicare beneficiaries with advanced cancer. The expected national coverage analysis completion date is May 17, 2019. For more information, we refer reader to the CMS website at: https://www.cms.gov/medicare-coverage-database/details/nca-tracking-sheet.aspx?NCAId=291. Lastly, we note that in the FY 2019 IPPS/LTCH proposed rule (83 FR 20294), we discussed possible payment alternatives and invited public comments regarding the most appropriate mechanism to provide payment to hospitals for new technologies such as CAR T-cell therapy drugs, including through the use of new technology add-on payments. We also invited public comments on how they would affect incentives to encourage lower drug prices. As discussed further in section II.F.2.d. of the preamble of this final rule, building on President Trump's Blueprint to Lower Drug Prices and Reduce Out-of-Pocket Costs, the CMS Center for Medicare and Medicaid Innovation (Innovation Center) is soliciting public comment in the CY 2019 OPPS/ASC proposed rule on key design considerations for developing a potential model that would test private market strategies and introduce competition to improve quality of care for beneficiaries, while reducing both Medicare expenditures and beneficiaries' out-of- pocket spending. Given the relative newness of CAR T-cell therapy, the potential model, and our request for feedback on this model approach, we believe that it would be premature to adopt changes to our existing payment mechanisms, including structural changes in new technology add- on payments. Therefore, we disagree with commenters who have requested such changes under the IPPS for FY 2019. b. VYXEOSTM (Cytarabine and Daunorubicin Liposome for Injection) Jazz Pharmaceuticals, Inc. submitted an application for new technology add-on payments for the VYXEOSTM technology for FY 2019. (We note that Celator Pharmaceuticals, Inc. submitted an application for new technology add-on payments for VYXEOSTM for FY 2018. However, Celator Pharmaceuticals did not receive FDA approval by the July 1, 2017 deadline for applications for FY 2018.) VYXEOSTM was approved by FDA on August 3, 2017, for the treatment of adults with newly diagnosed therapy-related acute myeloid leukemia (t-AML) or AML with myelodysplasia-related changes (AML-MRC). AML is a type of cancer in which the bone marrow makes abnormal myeloblasts (immature bone marrow white blood cells), red blood cells, and platelets. If left untreated, AML progresses rapidly. Normally, the bone marrow makes blood stem cells that develop into mature blood cells over time. Stem cells have the potential to develop into many different cell types in the body. Stem cells can act as an internal repair system, dividing, essentially without limit, to replenish other cells. When a stem cell divides, each new cell has the potential to either remain a stem cell or become a specialized cell, such as a muscle cell, a red blood cell, or a brain cell, among others. A blood stem cell may become a myeloid stem cell or a lymphoid stem cell. Lymphoid stem cells become white blood cells. A myeloid stem cell becomes one of three types of mature blood cells: (1) Red blood cells that carry oxygen and other substances to body tissues; (2) white blood cells that fight infection; or (3) platelets that form blood clots and help to control bleeding. In patients diagnosed with AML, the myeloid stem cells usually become a type of myeloblast. The myeloblasts in patients diagnosed with AML are abnormal and do not become healthy white blood cells. Sometimes in patients diagnosed with AML, too many stem cells become abnormal red blood cells or platelets. These abnormal cells are called leukemia cells or blasts. AML is defined by the World Health Organization (WHO) as greater than 20 percent blasts in the bone marrow or blood. AML can also be diagnosed if the blasts are found to have a chromosome change that occurs only in a specific type of AML diagnosis, even if the blast percentage does not reach 20 percent. Leukemia cells can build up in the bone [[Page 41300]] marrow and blood, resulting in less room for healthy white blood cells, red blood cells, and platelets. When this occurs, infection, anemia, or increased risk for bleeding may result. Leukemia cells can spread outside the blood to other parts of the body, including the central nervous system (CNS), skin, and gums. Treatment of AML diagnoses usually consists of two phases; remission induction and post-remission therapy. Phase one, remission induction, is aimed at eliminating as many myeloblasts as possible. The most common used remission induction regimens for AML diagnoses are the ``7+3'' regimens using an antineoplastic and an anthracycline. Cytarabine and daunorubicin are two commonly used drugs for ``7+3'' remission induction therapy. Cytarabine is continuously administered intravenously over the course of 7 days, while daunorubicin is intermittently administered intravenously for the first 3 days. The ``7+3'' regimen typically achieves a 70 to 80 percent complete remission (CR) rate in most patients under 60 years of age. High rates of CR are not generally seen in older patients for a number of reasons, such as different leukemia biology, much higher incidence of adverse cytogenetic abnormalities, higher rate of multidrug resistant leukemic cells, and comparatively lower patient performance status (the standard criteria for measuring how the disease impacts a patient's daily living abilities). Intensive induction therapy has worse outcomes in this patient population.\78\ The applicant asserted that many older adults diagnosed with AML have a poor performance status \79\ at presentation and multiple medical comorbidities that make the use of intensive induction therapy quite difficult or contraindicated altogether. Moreover, the CR rates of poor-risk patients diagnosed with AML are substantially higher in patients over 60 years of age; owing to a higher proportion of secondary AML, disease developing in the setting of a prior myeloid disorder.\80\ --------------------------------------------------------------------------- \78\ Juliusson, G., Lazarevic, V., Horstedt, A.S., Hagberg, O., Hoglund, M., ``Acute myeloid leukemia in the real world: why population-based registries are needed'', Blood, 2012 Apr 26; vol. 119(17), pp. 3890-9. \79\ Stone, R.M., et al., (2004), ``Acute myeloid leukemia.

According to the applicant, while CR rates of success vary widely depending on underlying disease biology and host factors, there is a lower success rate overall in achievement of CR with ``7 +3'' regimens compared to VYXEOSTM therapy. According to the applicant, ``7+3'' regimens produce a CR rate of approximately 50 percent in younger adult patients who have relapsed, but were in CR for at least 1 year.\81\ --------------------------------------------------------------------------- \81\ Kantarjian, H., Rayandi, F., O'Brien, S., et al., ``Intensive chemotherapy does not benefit most older patients (age 70 years and older) with acute myeloid leukemia,'' Blood, 2010, vol. 116(22), pp. 4422. --------------------------------------------------------------------------- VYXEOSTM is a nano-scale liposomal formulation containing a fixed combination of cytarabine and daunorubicin in a 5:1 molar ratio. This formulation was developed by the applicant using a proprietary system known as CombiPlex. According to the applicant, CombiPlex addresses several fundamental shortcomings of conventional combination regimens, specifically the conventional ``7+3'' free drug dosing, as well as the challenges inherent in combination drug development, by identifying the most effective synergistic molar ratio of the drugs being combined in vitro, and fixing this ratio in a nano- scale drug delivery complex to maintain the optimized combination after administration and ensuring exposure of this ratio to the tumor. Cytarabine and daunorubicin are co-encapsulated inside the VYXEOSTM liposome at a fixed ratiometrically, optimized 5:1 cytarabine: daunorubicin molar ratio. According to the applicant, encapsulation maintains the synergistic ratios, reduces degradation, and minimizes the impact of drug transporters and the effect of known resistant mechanisms. The applicant stated that the 5:1 molar ratio has been shown, in vitro, to maximize synergistic antitumor activity across multiple leukemic and solid tumor cell lines, including AML, and in animal model studies to be optimally efficacious compared to other cytarabine: daunorubicin ratios. In addition, the applicant stated that in clinical studies, the use of VYXEOSTM has demonstrated consistently more efficacious results than the conventional ``7+3'' free drug dosing. VYXEOSTM is intended for intravenous administration after reconstitution with 19 mL sterile water for injection. VYXEOSTM is administered as a 90-minute intravenous infusion on days 1, 3, and 5 (induction therapy), as compared to the ``7+3'' free drug dosing, which consists of two individual drugs administered on different days, including 7 days of continuous infusion. With regard to the newness criterion, as discussed earlier, if a technology meets all three of the substantial similarity criteria, it would be considered substantially similar to an existing technology and would not be considered ``new'' for purposes of new technology add-on payments. With regard to the first criterion, whether a product uses the same or a similar mechanism of action to achieve a therapeutic outcome, the applicant asserted that VYXEOSTM does not use the same or similar mechanism of action to achieve a therapeutic outcome as any other drug assigned to the same or a different MS-DRG. The applicant stated that no other AML treatment is designed, nor is able, to deliver a fixed, ratiometrically optimized and synergistic drug:drug ratio of 5:1 cytarabine to daunorubicin, and selectively target and accumulate at the site of malignancy, while minimizing unwanted exposure, which the applicant based on the data results of preclinical and clinical studies of the use of VYXEOSTM. The applicant indicated that VYXEOSTM is a nano-scale liposomal formulation of a fixed combination of cytarabine and daunorubicin. Further, the applicant stated that the rationale for the development of VYXEOSTM is based on prolonged delivery of synergistic drug ratios utilizing the applicant's proprietary, ratiometric CombiPlex technology. According to the applicant, conventional ``7+3'' free drug dosing has no delivery complex, and these individual drugs are administered without regard to their ratio dependent interaction. According to the applicant, enzymatic inactivation and imbalanced drug efflux and transporter expression reduce drug levels in the cell. Further, decreased cytotoxicity leads to cell survival, emergence of drug resistant cells, and decreased overall survival. The applicant provided the results of clinical studies to demonstrate that the CombiPlex technology and the ratiometric dosing of VYXEOSTM represent a shift in anticancer agent delivery, whereby the fixed, optimized dosing provides less drug to achieve improved efficacy, while maintaining a favorable risk-benefit profile. The results of this ratiometric dosing approach are in contrast to the typical combination chemotherapy [[Page 41301]] development that establishes the recommended dose of one agent and then adds subsequent drugs to the combination at increasing concentrations until the aggregate effects of toxicity are considered to be limiting (the ``7+3'' drug regimen). According to the applicant, this current approach to combination chemotherapy development assumes that maximum therapeutic activity will be achieved with maximum dose intensity for all drugs in the combination, and ignores the possibility that more subtle concentration-dependent drug interactions could result in frankly synergistic outcomes. The applicant maintained that, while VYXEOSTM contains no novel active agents, its innovative drug delivery mechanism appears to be a superior way to deliver the two active compounds in an effort to optimize their efficacy in killing leukemic blasts. However, in the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20296), we stated that we were concerned it is possible that VYXEOSTM may use a similar mechanism of action compared to currently available treatment options because both the current treatment regimen and VYXEOSTM are used in the treatment of AML by intravenous administration of cytarabine and daunorubicin. We specifically stated that we were concerned that the mechanism of action of the ratiometrically fixed liposomal formulation of VYXEOSTM is the same or similar to that of the current intravenous administration of cytarabine and daunorubicin. With respect to the second criterion, whether a product is assigned to the same or a different MS-DRG, we stated that we believe that potential cases representing patients who may be eligible for treatment involving VYXEOSTM would be assigned to the same MS-DRGs as cases representing patients who receive treatment for diagnoses of AML. With respect to the third criterion, whether the new use of the technology involves the treatment of the same or similar type of disease and the same or similar patient population, the applicant asserted that VYXEOSTM is indicated for use in the treatment of patients who have been diagnosed with high-risk AML. The applicant also asserted that VYXEOSTM is the first and only approved fixed combination of cytarabine and daunorubicin and is designed to uniquely control the exposure using a nano-scale drug delivery vehicle leading to statistically significant improvements in survival in patients who have been diagnosed with high-risk AML compared to the conventional ``7+3'' free drug dosing. We stated in the proposed rule that we believe that VYXEOSTM involves the treatment of the same patient population as other AML treatment therapies. The following unique ICD-10-PCS codes were created to describe the administration of VYXEOSTM: XW033B3 (Introduction of cytarabine and caunorubicin liposome antineoplastic into peripheral vein, percutaneous approach, new technology group 3) and XW043B3 (Introduction of cytarabine and daunorubicin liposome antineoplastic into central vein, percutaneous approach, new technology group 3). In the FY 2019 IPPS/LTCH PPS proposed rule, we invited public comments on whether VYXEOSTM is substantially similar to existing technology, including whether the mechanism of action of VYXEOSTM differs from the mechanism of action of the currently available treatment regimen. We also invited public comments on whether VYXEOSTM meets the newness criterion. Comment: Several commenters supported the novel and effective ratiometric dosing drug delivery mechanism of VYXEOSTM. The applicant stated that preclinical and clinical evidence confirms the differentiated mechanism of action of VYXEOSTM from other available treatment options. The applicant also reiterated that it believed VYXEOSTM is not substantially similar to any other currently available drug and is highly differentiated from the conventional ``7+3'' free drug dosing treatment regimen. Response: We appreciate the commenters' and the applicant's input on whether VYXEOSTM meets the newness criterion. After consideration of the public comments we received, we believe that VYXEOSTM has a unique mechanism of action and, therefore, is not substantially similar to other drug therapies. We believe that the liposomal formulation used to combine daunorubicin and cytarabine to create VYXEOSTM is unique and distinct from other anti- cancer agents and, therefore, we believe that VYXEOSTM meets the newness criterion. With regard to the cost criterion, the applicant conducted the following analysis. The applicant used the FY 2016 MedPAR Hospital Limited Data Set (LDS) to assess the MS-DRGs to which cases representing potential patient hospitalizations that may be eligible for treatment involving VYXEOSTM would most likely be assigned. These potential cases representing patients who may be VYXEOSTM candidates were identified if they: (1) Were diagnosed with acute myeloid leukemia (AML); and (2) received chemotherapy during their hospital stay. The cohort was further limited by excluding patients who had received bone marrow transplants. The cohort used in the analysis is referred to in this discussion as the primary cohort. According to the applicant, the primary cohort of cases spans 131 unique MS-DRGs, 16 of which contained more than 10 cases. The most common MS-DRGs are MS-DRG 837, 834, 838, and 839. These 4 MS-DRGs account for 4,457 (81 percent) of the 5,483 potential cases in the cohort. The case-weighted unstandardized charge per case is approximately $185,844. The applicant then removed charges related to other chemotherapy agents because VYXEOSTM would replace the need for the use of current chemotherapy agents. The applicant explained that charges for chemotherapy drugs are grouped with charges for oncology, diagnostic radiology, therapeutic radiology, nuclear medicine, CT scans, and other imaging services in the ``Radiology Charge Amount.'' According to the applicant, removing 100 percent of the ``Radiology Charge Amount'' would understate the cost of care for treatment involving VYXEOSTM for patients who may be eligible because treatment involving VYXEOSTM would be unlikely to replace many of the services captured in the ``Radiology Charge Amount'' category. The applicant found that chemotherapy charges represent less than 20 percent of the charges associated with revenue centers grouped into the ``Radiology Charge Amount'' and removed 20 percent of the radiology charge amount in order to capture the effect of removing chemotherapy pharmacy charges. The applicant noted that regardless of the type of induction chemotherapy, patients being treated for AML have AML-related complications, such as bleeding or infection that require supportive care drug therapy. For this reason, it is expected that eligible patients receiving treatment involving VYXEOSTM will continue to incur other pharmacy and IV therapy charges for AML-related complications. After removing the charges for the prior technology, the applicant standardized the charges. The applicant then applied an inflation factor of 1.09357, the value used in the FY 2018 IPPS/LTCH PPS final rule (82 FR 38527) to update the charges from FY 2016 to FY 2018. According to the applicant, for the primary new technology add-on payment cohort, the cost criterion was [[Page 41302]] met without consideration of VYXEOSTM charges. The average case-weighted standardized charge was $170,458, which exceeded the average case-weighted Table 10 MS-DRG threshold amount of $82,561 by $87,897. The applicant provided additional analyses with the inclusion of VYXEOSTM charges under 3-vial, 4-vial, 6-vial, and 10-vial treatment scenarios. According to the applicant, the cost criterion was satisfied in each of these scenarios, with charges in excess of the average case-weighted threshold amount. Finally, the applicant also provided the following sensitivity analyses (that did not include charges for VYXEOSTM) using the methodology above: Sensitivity Analysis 1--limited the cohort to patients who have been diagnosed with AML without remission (C92.00 or C92.50) who received chemotherapy and did not receive bone marrow transplant. Sensitivity Analysis 2--the modified cohort was limited to patients who have been diagnosed with relapsed AML who received chemotherapy and did not receive bone marrow transplant. Sensitivity Analysis 3--the modified cohort was limited to patients who have been diagnosed with AML and who did not receive bone marrow transplant. Sensitivity Analysis 4--the primary cohort was maintained, but 100 percent of the charges for revenue centers grouped into the ``Pharmacy Charge Amount'' were excluded. Sensitivity Analysis 5--identified patients who have been diagnosed with AML in remission. The applicant noted that, in all of the sensitivity analysis scenarios, the average case-weighted standardized charge per case exceeded the average case-weighted Table 10 MS-DRG threshold amount. Based on all of the analyses above, the applicant maintained that VYXEOSTM met the cost criterion. We invited public comments on whether VYXEOSTM meets the cost criterion. Comment: The applicant noted the detailed summary presented in the proposed rule of the cost analysis of the VYXEOSTM, including a primary cohort analysis and five sensitivity analyses. The applicant stated that, in each of the analyses, it was demonstrated that the average case-weighted standardized charge per case for the applicable MS-DRGs exceeded the average case-weighted threshold amount before considering the average per patient cost of VYXEOSTM to the hospital. Response: We appreciate the applicant's input. After consideration of the public comments we received, we believe that VYXEOSTM meets the cost criterion. With regard to substantial clinical improvement, according to the applicant, clinical data results have shown that the use of VYXEOSTM represents a substantial clinical improvement for the treatment of AML in newly diagnosed high-risk, older (60 years of age and older) patients, marked by statistically significant improvements in overall survival, event free survival and response rates, and in relapsed patients age 18 to 65 years of age, where a statistically significant improvement in overall survival has been documented for the poor-risk subset of patients as defined by the European Prognostic Index. In both groups of patients, the applicant stated that there was significant improvement in survival for the high- risk patient group. The applicant provided the following specific clinical data results. The applicant stated that clinical data results show that treatment with VYXEOSTM for older patients (60 years of age and older) who have been diagnosed with untreated, high-risk AML will result in superior survival rates, as compared to patients treated with conventional ``7+3'' free drug dosing. The applicant provided a summary of the pivotal Phase III Study 301 in which 309 patients were enrolled, with 153 patients randomized to the VYXEOSTM treatment arm and 156 to the ``7+3'' free drug dosing treatment arm. Among patients who were 60 to 69 years old, there were 96 patients in the VYXEOSTM treatment arm and 102 in the ``7+3'' free drug dosing treatment arm. For patients who were 70 to 75 years old, there were 57 and 54 patients in each treatment arm, respectively. The applicant noted that the data results from the Phase III Study 301 demonstrated that first-line treatment of patients diagnosed with high- risk AML in the VYXEOSTM treatment arm resulted in substantially greater median overall survival of 9.56 months versus 5.95 months in the ``7+3'' free drug dosing treatment arm (hazard ratio of 0.69; p=0.005). The applicant further asserted that high-risk, older patients (60 years old and older) previously untreated for diagnoses of AML will have a lower risk of early death when treated with VYXEOSTM than those treated with the conventional ``7+3'' free drug dosing. The applicant cited Medeiros, et al.,\82\ which reported a large observational study of Medicare beneficiaries and noted the following: The data result of the study showed that 50 to 60 percent of elderly patients diagnosed with AML remain untreated following diagnosis; treated patients were more likely younger, male, and married, and less likely to have secondary diagnoses of AML, poor performance indicators, and poor comorbidity scores compared to untreated patients; and in multivariate survival analyses, treated patients exhibited a significant 33 percent lower risk of death compared to untreated patients. --------------------------------------------------------------------------- \82\ Medeiros, B., et al., ``Big data analysis of treatment patterns and outcomes among elderly acute myeloid leukemia patients in the United States'', Ann Hematol, 2015, vol. 94(7), pp. 1127- 1138. --------------------------------------------------------------------------- Based on data from the Phase III Study 301,\83\ the applicant cited the following results: The rate of 60-day mortality was less in the VYXEOSTM treatment arm (13.7 percent) versus the ``7+3'' free drug dosing treatment arm (21.2 percent); the reduction in early mortality was due to fewer deaths from refractory AML (3.3 percent versus 11.3 percent), with very similar rates of 60-day mortality due to adverse events (10.4 percent versus 9.9 percent); there were fewer deaths in the VYXEOSTM treatment arm versus the ``7+3'' free drug dosing treatment arm during the treatment phase (7.8 percent versus 11.3 percent); and there were fewer deaths in the VYXEOSTM treatment arm during the follow-up phase than in the ``7+3'' free drug dosing treatment arm (59.5 percent versus 71.5 percent). --------------------------------------------------------------------------- \83\ Lancet, J., et al., ``Final results of a Phase III randomized trial of VYXEOS (CPX-351) versus 7+3 in older patients with newly diagnosed, high-risk (secondary) AML''. Abstract and oral presentation at American Society of Clinical Oncology (ASCO), June 2016. --------------------------------------------------------------------------- The applicant asserted that high-risk, older patients (60 years old and older) previously untreated for a diagnosis of AML exhibited statistically significant improvements in response rates after treatment with VYXEOSTM versus treatment with the conventional ``7+3'' free drug chemotherapy dosing, suggesting that the use of VYXEOSTM is a superior pre-transplant induction treatment versus ``7+3'' free drug dosing. Restoration of normal hematopoiesis is the ultimate goal of any therapy for AML diagnoses. The first phase of treatment consists of induction chemotherapy, in which the goal is to ``empty'' the bone marrow of all hematopoietic elements (both benign and malignant), and to allow repopulation of the marrow with normal cells, thereby yielding remission. According to the applicant, post-induction response rates were [[Page 41303]] significantly higher following the use of VYXEOSTM, which elicited a 47.7 percent total response rate and a 37.3 percent rate for CR, whereas the total response and CR rates for the ``7+3'' free drug dosing arm were 33.3 percent and 25.6 percent, respectively. The CR+CRi rates for patients who were 60 to 69 years of age were 50.0 percent in the VYXEOSTM treatment arm and 36.3 percent in the ``7+3'' free drug dosing treatment arm, with an odds ratio of 1.76 (95 percent CI, 1.00-3.10). For patients who were 70 to 75 years old, the rates of CR+CRi were 43.9 percent in the VYXEOSTM treatment arm and 27.8 percent in the ``7+3'' free drug dosing treatment arm. The applicant asserted that VYXEOSTM treatment will enable high-risk, older patients (60 years old and older) to bridge to allogeneic transplant, and VYXEOSTM treated responding patients will have markedly better outcomes following transplant. The applicant stated that diagnoses of secondary AML are considered incurable with standard chemotherapy approaches and, as with other high-risk hematological malignancies, transplantation is a useful treatment alternative. The applicant further stated that autologous HSCT has limited effectiveness and at this time, only allogeneic HSCT with full intensity conditioning has been reported to produce long-term remissions. However, the applicant stated that the clinical study by Medeiros, et al. reported that, while the use of allogeneic HSCT is considered a potential cure for AML, its use is limited in older patients because of significant baseline comorbidities and increased transplant-related morbidity and mortality. Patients in either treatment arm of the Phase III Study 301 responding to induction with a CR or CR+CRi (n=125) were considered for allogeneic hematopoietic cell transplant (HCT) when possible. In total, 91 patients were transplanted: 52 (34 percent) from the VYXEOSTM treatment arm and 39 (25 percent) from the ``7+3'' free drug dosing treatment arm. Patient and AML characteristics were similar according to randomized arm, including percentage of patients in each treatment arm that underwent transplant in CR+CRi status. However, the applicant noted that the VYXEOSTM treatment arm contained a higher percentage of older patients (70 years old or older) who were transplanted (VYXEOSTM, 31 percent; ``7+3'' free drug dosing, 15 percent).\84\ --------------------------------------------------------------------------- \84\ Stone Hematology 2004; Gordon AACR 2016; NCI. Available at: www.cancer.gov. --------------------------------------------------------------------------- According to the applicant, patient outcome following transplant strongly favored patients in the VYXEOSTM treatment arm. The Kaplan-Meier analysis of the 91 transplanted patients landmarked at the time of HCT showed that patients in the VYXEOSTM treatment arm had markedly better overall survival (hazard ratio 0.46; p=0.0046). The time-dependent Adjustment Model (Cox proportional hazard ratio) was used to evaluate the contribution of VYXEOSTM treatment to overall survival rate after adjustment for transplant and showed that VYXEOSTM treatment remained a significant contributor, even after adjusting for transplant. The time-dependent Cox hazard ratio for overall survival rates in the VYXEOSTM treatment arm versus the ``7+3'' free drug dosing treatment arm was 0.51 (95 percent CI, 0.35-0.75; p=.0007). The applicant asserted that VYXEOSTM treatment of previously untreated older patients (60 years old and older) diagnosed with high-risk AML increases the response rate and improves survival compared to conventional ``7+3'' free drug dosing treatment in patients diagnosed with FLT3 mutation. The applicant noted the following: Approximately 20 to 30 percent of AML patients harbor some form of FLT3 mutation, AML patients with a FLT3 mutation have a higher relapse rate and poorer prognosis than the overall population diagnosed with AML, and the most common type of mutation is internal tandem duplication (ITD) mutation localized to a membrane region of the receptor. The applicant cited Gordon, et al., 2016,\85\ which reported on the significant anti-leukemic activity of VYXEOSTM treatment in AML blasts exhibiting high-risk characteristics, including FLT3-ITD, that are typically associated with poor outcomes when treated with conventional ``7+3'' free drug dosing treatment. To determine whether the improved complete remission and overall survival rates of treatment using VYXEOSTM as compared to conventional ``7+3'' free drug dosing treatment are attributable to liposome-mediated altered drug PK or direct cellular interactions with specific AML blast samples, the authors evaluated cytotoxicity in 53 AML patient specimens. Cytotoxicity results were correlated with patient characteristics, as well as VYXEOSTM treatment cellular uptake and molecular phenotype status including FLT3-ITD, which is a predictor of poor patient outcomes to conventional ``7+3'' free drug dosing treatment. The applicant stated that a notable result from this research was the observation that AML blasts exhibiting the FLT3-ITD phenotype exhibited some of the lowest IC 50 (the 50 percent inhibitory concentration) values and, as a group, were five-fold more sensitive to the VYXEOSTM treatment than those with wild type FLT3. In addition, there was evidence that increased sensitivity to VYXEOSTM treatment was associated with increased uptake of the drug-laden liposomes by the patient-derived AML blasts. The applicant noted that Gordon, et al. 2016, concluded taken together, the data are consistent with clinical observations where VYXEOSTM treatment retains significant anti-leukemic activity in AML patients exhibiting high-risk characteristics. The applicant also noted that a subanalysis of Phase III Study 301 identified 22 patients who had been diagnosed with FLT3 mutation in the VYXEOSTM treatment arm and 20 in the ``7+3'' free drug dosing treatment arm, which resulted in the following response rates of FLT3 mutated patients, which were higher with VYXEOSTM treatments (15 of 22, 68.2 percent) versus ``7+3'' free drug dosing treatments (5 of 20, 25.0 percent); and the Kaplan-Meier analysis of the 42 FLT3 mutated patients showed that patients in the VYXEOSTM treatment arm had a trend towards better overall survival rates (hazard ratio 0.57; p=0.093). --------------------------------------------------------------------------- \85\ Gordon, M., Tardi, P., Lawrence, M.D., et al., ``CPX-351 cytotoxicity against fresh AML blasts increased for FLT3-ITD+ cells and correlates with drug uptake and clinical outcomes,'' Abstract 287 and poster presented at AACR (American Association for Cancer Research), April 2016. ---------------------------------------------------------------------------The applicant asserted that younger patients (18 to 65 years old) with poor risk first relapse AML have shown higher response rates with VYXEOSTM treatment versus conventional ``salvage'' chemotherapy. Overall, the applicant stated that the use of VYXEOSTM had an acceptable safety profile in this patient population based on 60-day mortality data. Study 205 \86\ was a randomized study comparing VYXEOSTM treatment against the investigator's choice of first ``salvage'' chemotherapy in patients who had been diagnosed with relapsed AML after a first remission lasting greater than 1 month (VYXEOSTM treatment arm, n=81 and ``7+3'' free drug dosing treatment arm, n=44; 18 to 65 years old). Investigator's choice was almost always based on cytarabine + anthracycline, usually with the addition [[Page 41304]] of one or two new agents. According to the applicant, treatment involving VYXEOSTM demonstrated a higher rate of morphological leukemia clearance among all patients, 43.2 percent versus 40.0 percent, and the advantage was most apparent in poor-risk patients, 78.7 percent versus 44.4 percent, as defined by the European Prognostic Index (EPI). In the subset analysis of this EPI poor-risk patient subset, the applicant stated there was a significant improvement in survival rate (6.6 versus 4.2 months median, hazard ratio=0.55, p=0.02) and improved response rate (39.3 percent versus 27 percent). The applicant also noted the following: The safety profile for the use of VYXEOSTM was qualitatively similar to that of control ``salvage'' therapy, with nearly identical 60-day mortality rates (14.8 percent versus 15.9 percent); among VYXEOSTM treated patients, those with no history of prior HSCT (n=59) had higher response rates (54.2 percent versus 37.8 percent) and lower 60-day mortality (10.2 percent versus 16.2 percent); overall, the use of VYXEOSTM had acceptable safety based on 60-day mortality data, with somewhat higher frequency of neutropenia and thrombocytopenia-related grade III-IV adverse events. Even though these patients are younger (18 to 65 years old) than the population studied in Phase III Study 301 (60 years old and older), Study 205 patients were at a later stage of the disease and almost all had responded to first-line therapy (cytarabine + anthracycline) and had relapsed. The applicant also cited Cortes, et al. 2015,\87\ which reported that patients who have been diagnosed with first relapse AML have limited likelihood of response and short expected survival following ``salvage'' treatment with the results from literature showing that: --------------------------------------------------------------------------- \86\ Cortes, J., et al., ``Significance of prior HSCT on the outcome of salvage therapy with CPX-351 or conventional chemotherapy among first relapse AML patients.'' Abstract and poster presented at ASH 2011. \87\ Cortes, J., et al., (2015), ``Phase II, multicenter, randomized trial of CPX-351 (cytarabine:daunorubicin) liposome injection versus intensive salvage therapy in adults with first relapse AML,'' Cancer, January 2015, pp. 234-42. --------------------------------------------------------------------------- Mitoxantrone, etoposide, and cytarabine induced response in 23 percent of patients, with median overall survival of only 2 months. Modulation of deoxycitidine kinase by fludarabine led to the combination of fludarabine and cytarabine, resulting in a 36 percent CR rate with median remission duration of 39 weeks. First salvage gemtuzumab ozogamicin induced CR+CRp (or CR+CRi) response in 30 percent of patients with CD33+AML and, for patients with short first CR durations, appeared to be superior to cytarabine-based therapy. The applicant noted that Study 205 results showed the use of VYXEOSTM retained greater anti-leukemic efficacy in patients who have been diagnosed with poor-risk first relapse AML, and produced higher morphological leukemia clearance rates (78.7 percent) compared to conventional ``salvage'' therapy (44 percent). The applicant further noted that, overall, the use of VYXEOSTM had acceptable safety profile in this patient population based on 60-day mortality data. Based on all of the data presented above, the applicant concluded that VYXEOSTM represents a substantial clinical improvement over existing technologies. However, in the proposed rule, we stated we were concerned that, although there was an improvement in a number of outcomes in Phase III Study 301, specifically overall survival rate, lower risk of early death, improved response rates, better outcomes following transplant, increased response rate and overall survival in patients diagnosed with FLT3 mutation, and higher response rates versus conventional ``salvage'' chemotherapy in younger patients diagnosed with poor-risk first relapse, the improved outcomes may not be statistically significant. Furthermore, we indicated we were concerned that the overall improvement in survival from 5.95 months to 9.56 months may not represent a substantial clinical improvement. In addition, the rate of adverse events in both treatment arms of Study 205, given the theoretical benefit of reduced toxicity with the liposomal formulation, was similar for both the VYXEOSTM and ``7+3''free drug treatment groups. Therefore, we also were concerned that there is a similar rate of adverse events, such as febrile neutropenia (68 percent versus 71 percent), pneumonia (20 percent versus 15 percent), and hypoxia (13 percent versus 15 percent), with the use of VYXEOSTM as compared with the conventional ``7+3'' free drug regimen. We invited public comments on whether VYXEOSTM meets the substantial clinical improvement criterion. Comment: Several commenters supported the use of VYXEOSTM as a viable treatment option in the treatment of older adults who have been diagnosed with high-risk AML, and believed that clinically meaningful survival and response improvements have been and can be achieved for a highly difficult to treat population of patients with extremely limited treatment options. The applicant summarized the efficacy outcomes of the pivotal Phase III Study 301 and noted that significant improvement in overall survival was achieved with a hazard ratio of 0.69, p=0.005. The applicant indicated that, although many days of increased survival are desired rather than few, clinical benefit cannot be determined solely by the absolute number of days or months of survival increase. Rather, clinical benefit is determined by the relative improvement in survival. The applicant stated that, based on the data results from the Phase III Study 301, the observed improvement in median survival was 3.61 months (Control, 5.95m versus VYXEOS, 9.56m). In other words, a 3.61 month increase in median survival is substantial and of great benefit given an expected median survival of only 5.95 months for patients treated with control arm therapy. The applicant believed that this result was statistically significant and demonstrates clinically high benefits. Response: We appreciate the commenters' and the applicant's input in response to our concerns. After consideration of the public comments we received, we believe that based on the statistically significant increase in median survival rate from the Phase III Study 301, VYXEOSTM is a treatment option which offers a substantial clinical improvement over standard therapy for patients who have been diagnosed with AML. Therefore, we believe that VYXEOSTM meets the substantial clinical improvement criterion. Based on evaluation of the new technology add-on payment application and consideration of the public comments we received, we have determined that VYXEOSTM meets all of the criteria for approval for new technology add-on payments. Therefore, we are approving new technology add-on payments for VYXEOSTM for FY 2019. We expect that VYXEOSTM will be administered, as indicated, for use in the treatment of adults who have been newly diagnosed with therapy-related acute myeloid leukemia (t-AML) or AML with myelodysplasia-related changes (AML-MRC). Cases involving the use of VYXEOSTM that are eligible for new technology add-on payments will be identified by ICD-10-PCS procedure codes: XW033B3 (Introduction of cytarabine and caunorubicin liposome antineoplastic into peripheral vein, percutaneous approach, new technology group 3); and XW043B3 (Introduction of cytarabine and daunorubicin liposome antineoplastic into central vein, percutaneous approach, new technology group 3). [[Page 41305]] In its application, the applicant estimated that the average cost of a single vial for VYXEOSTM is $7,750 (daunorubicin 44 mg/ m2 and cytarabine 100 mg/m2). The applicant stated that the first induction of 6 vials is administered in the inpatient hospital setting, with 31 percent of the patients receiving a second induction of an administration of 4 vials. Of the 31 percent of the patients that receive the second induction, 85 percent of the patients receive the second induction in the inpatient hospital setting during the same inpatient stay of the first induction. The applicant further stated that 32 percent of all of the patients receive a first consolidation therapy of an administration of 3 vials, with 50 percent of these patients being treated in the inpatient hospital setting. The applicant also indicated that 50 percent of all of the patients receive a second consolidation therapy of an administration of 3 vials, with 40 percent of these patients being treated in the inpatient hospital setting. As is our past practice, based on the information above, we believe that it is appropriate to use an average to set the maximum amount of vials used in the inpatient hospital setting. For the induction therapy, all patients receive an administration of 6 vials for the first induction in the inpatient hospital setting, with 31 percent of all of the patients receiving a second induction therapy of an administration of 4 vials--of which 85 percent of these patients are treated in the inpatient hospital setting during the same stay as the first induction therapy. Therefore, we computed the average of 6 vials for the first induction plus 3.4 vials for the second induction (4 vials * 0.85), which results in a maximum average of 9.4 vials used in the inpatient hospital setting. Therefore, the maximum average cost for VYXEOSTM used in the inpatient hospital setting is $72,850 ($7,750 cost per vial * 9.4 vials). Under Sec. 412.88(a)(2), we limit new technology add-on payments to the lesser of 50 percent of the average cost of the technology, or 50 percent of the costs in excess of the MS-DRG payment for the case. As a result, the maximum new technology add-on payment for a case involving the use of VYXEOSTM is $36,425. c. VABOMERETM (Meropenem-vaborbactam) Melinta Therapeutics, Inc., submitted an application for new technology add-on payments for VABOMERETM for FY 2019. VABOMERETM is indicated for use in the treatment of adult patients who have been diagnosed with complicated urinary tract infections (cUTIs), including pyelonephritis, caused by designated susceptible bacteria. VABOMERETM received FDA approval on August 29, 2017. Complicated urinary tract infections (cUTIs) are defined as chills, rigors, or fever (temperature of greater than or equal to 38.0 [deg]C); elevated white blood cell count (greater than 10,000/mm3), or left shift (greater than 15 percent immature PMNs); nausea or vomiting; dysuria, increased urinary frequency, or urinary urgency; lower abdominal pain or pelvic pain. Acute pyelonephritis is defined as chills, rigors, or fever (temperature of greater than or equal to 38.0 [deg]C); elevated white blood cell count (greater than 10,000/mm3), or left shift (greater than 15 percent immature PMNs); nausea or vomiting; dysuria, increased urinary frequency, or urinary urgency; flank pain; costo-vertebral angle tenderness on physical examination. Risk factors for infection with drug-resistant organisms do not, on their own, indicate a cUTI.\88\ The increasing incidence of multidrug-resistant gram-negative bacteria, such as carbapenem-resistant Enterobacteriacea (CRE), has resulted in a critical need for new antimicrobials. --------------------------------------------------------------------------- \88\ Hooton, T. and Kalpana, G., 2018, ``Acute complicated urinary tract infection (including pyelonephritis) in adults,'' In A. Bloom (Ed.), UpToDate. Available at: https://www.uptodate.com/contents/acute-complicated-urinary-tract-infection-including-pyelonephritis-in-adults. --------------------------------------------------------------------------- The applicant reported that it has developed a beta-lactamase combination antibiotic, VABOMERETM, to treat cUTIs, including those caused by certain carbapenem-resistant organisms. By combining the carbapenem class antibiotic meropenem with vaborbactam, VABOMERETM protects meropenem from degradation by certain CRE strains. The applicant stated that meropenem, a carbapenem, is a broad spectrum beta-lactam antibiotic that works by inhibiting cell wall synthesis of both gram-positive and gram-negative bacteria through binding of penicillin-binding proteins (PBP). Carbapenemase producing strains of bacteria have become more resistant to beta-lactam antibiotics, such as meropenem. However, meropenem in combination with vaborbactam, inhibits the carbapenemase activity, thereby allowing the meropenem to bind PBP and kill the bacteria. According to the applicant, vaborbactam, a boronic acid inhibitor, is a first-in class beta-lactamase inhibitor. Vaborbactam blocks the breakdown of carbapenems, such as meropenem, by bacteria containing carbapenemases. Although vaborbactam has no antibacterial properties, it allows for the treatment of resistant infections by increasing bacterial sensitivity to meropenem. New carbapenemase producing strains of bacteria have become more resistant to beta-lactam antibiotics. However, meropenem in combination with vaborbactam, can inhibit the carbapenemase enzyme, thereby allowing the meropenem to bind PBP and kill the bacteria. The applicant stated that the vaborbactem component of VABOMERETM helps to protect the meropenem from degradation by certain beta-lactamases, such as Klebsiella pneumonia carbapenemase (KPC). According to the applicant, VABOMERETM is the first of a novel class of beta-lactamase inhibitors. The applicant asserted that VABOMERETM's use of vaborbactam to restore the efficacy of meropenem is a novel approach to fighting antimicrobial resistance. The applicant stated that VABOMERETM is indicated for use in the treatment of adult patients 18 years old and older who have been diagnosed with cUTIs, including pyelonephritis. The recommended dosage of VABOMERETM is 4 grams (2 grams of meropenem and 2 grams of vaborbactam) administered every 8 hours by intravenous (IV) infusion over 3 hours with an estimated glomerular filtration rate (eGFR) greater than or equal to 50 ml/min/1.73m\2\. The recommended dosage of VABOMERETM for patients with varying degrees of renal function is included in the prescribing information. The duration of treatment is for up to 14 days. As discussed earlier, if a technology meets all three of the substantial similarity criteria, it would be considered substantially similar to an existing technology and would not be considered ``new'' for purposes of new technology add-on payments. With regard to the first criterion, whether a product uses the same or a similar mechanism of action to achieve a therapeutic outcome, according to the applicant, VABOMERETM is designed primarily for the treatment of gram-negative bacteria that are resistant to other current antibiotic therapies. The applicant stated that VABOMERETM does not use the same or similar mechanism of action to achieve a therapeutic outcome. The applicant asserted that the vaborbactam component of VABOMERETM is a new class of beta-lactamase inhibitor that protects meropenem from degradation by certain enzymes such as carbapenamases. The applicant indicated that the structure of [[Page 41306]] vaborbactam is distinctly optimized for inhibition of serine carbapenamases and for combination with a carbapenem antibiotic. Beta- lactamase inhibitors are agents that inhibit bacterial enzymes--enzymes that destroy beta-lactam antibiotics and result in resistance to first- line as well as ``last defense'' antimicrobials used in hospitals. According to the applicant, in order for carbapenems to be effective these enzymes must be inhibited. The applicant stated that the addition of vaborbactam as a potent inhibitor against Class A and C serine beta- lactamases, particularly KPC, represents a new mechanism of action. According to the applicant, VABOMERETM's use of vaborbactam to restore the efficacy of meropenem is a novel approach and that the FDA's approval of VABOMERETM for the treatment of cUTIs represents a significant label expansion because mereopenem alone (without the addition of vaborbactam) is not indicated for the treatment of patients with cUTI infections. Therefore, the applicant maintained that this technology and resistance-fighting mechanism involved in the therapeutic effect achieved by VABOMERETM is distinct from any other existing product. The applicant noted that VABOMERETM was designated as a qualified infectious disease product (QIDP) in January 2014. This designation is given to antibacterial products that treat serious or life-threatening infections under the Generating Antibiotic Incentives Now (GAIN) title of the FDA Safety and Innovation Act. In the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20300), we stated that we believed, although the molecular structure of the vaborbactam component of VABOMERETM is unique, the bactericidal action of VABOMERETM is the same as meropenem alone. In addition, we noted that there are other similar beta-lactam/beta-lactamase inhibitor combination therapies currently available as treatment options. We invited public comments on whether VABOMERETM's mechanism of action is similar to other existing technologies. With respect to the second criterion, whether a product is assigned to the same or a different MS-DRG, the applicant asserted that patients who may be eligible to receive treatment involving VABOMERETM include hospitalized patients who have been diagnosed with a cUTI. These potential cases can be identified by a variety of ICD-10-CM diagnosis codes. Therefore, potential cases representing patients who have been diagnosed with a cUTI who may be eligible for treatment involving VABOMERETM can be mapped to multiple MS-DRGs. The following are the most commonly used MS-DRGs for patients who have been diagnosed with a cUTI: MS-DRG 690 (Kidney and Urinary Tract Infections without MCC); MS-DRG 853 (Infectious and Parasitic Diseases with O.R. Procedure with MCC); MS-DRG 870 (Septicemia or Sever Sepsis with Mechanical Ventilation 96+ Hours); MS- DRG 871 (Septicemia or Severe Sepsis without Mechanical Ventilation 96+ Hours with MCC); and MS-DRG 872 (Septicemia or Severe Sepsis without Mechanical Ventilation 96+ Hours without MCC). Potential cases representing patients who may be eligible for treatment with VABOMERETM would be assigned to the same MS-DRGs as cases representing hospitalized patients who have been diagnosed with a cUTI. With respect to the third criterion, whether the use of the technology involves the treatment of the same or similar type of disease and the same or similar patient population, the applicant asserted that the use of VABOMERETM would treat a different patient population than existing and currently available treatment options. According to the applicant, VABOMERETM's use of vaborbactam to restore the efficacy of meropenem is a novel approach to fighting the global and national public health crisis of antimicrobial resistance, and as such, the use of VABOMERETM reaches different and expanded patient populations. The applicant further asserted that future patient populations are saved as well because the growth of resistant infections is slowed. The applicant believed that, because of the threat posed by gram-negative bacterial infections and the limited number of available treatments currently on the market or in development, the combination structure and development of VABOMERETM and its potential expanded use is new. We stated in the proposed rule that while the applicant believes that VABOMERETM treats a different patient population, we note that VABOMERETM is only approved for use in the treatment of adult patients who have been diagnosed with cUTIs. Therefore, we stated that it appears that VABOMERETM treats the same population (adult patients with a cUTI) and there are already other treatment options available for diagnoses of cUTIs. In the proposed rule, we stated that we were concerned VABOMERETM may be substantially similar to existing beta- lactam/beta-lactamase inhibitor combination therapies. As noted in the proposed rule and above, we were concerned that VABOMERETM may have a similar mechanism of action, treats the same population (patients with a cUTI) and would be assigned to the same MS-DRGs (similar to existing beta-lactam/beta-lactamase inhibitor combination therapies currently available as treatment options). We invited public comments on whether VABOMERETM meets the substantial similarity criteria and the newness criterion. Comment: The applicant addressed the issue regarding the substantial similarity criteria and recommended CMS apply its standards under the newness criterion in a manner that recognizes the innovative nature and unique aspects of VABOMERETM. The applicant explained that meropenem alone is not indicated to treat a diagnosis of a cUTI and, moreover, is not active against KPC-producing CRE. The applicant stated that the action of the vaborbactam's protection of the meropenem is fundamental and essential to how VABOMERETM acts on and inhibits bacterial enzymes, and allows VABOMERETM to treat even those infections that would otherwise be resistant and not susceptible to therapy with meropenem alone. The applicant believed that, accordingly, VABOMERETM's mechanism of action is distinct from that of meropenem and is not the same. The applicant further explained that, meropenem is degraded by beta-lactamases enzymes, including KPC enzymes, and, therefore, is ineffective against KPC-producing CRE. The applicant indicated that VABOMERETM, in contrast, is not degraded by these enzymes and is able to provide effective treatment against infections that are not susceptible to meropenem. The applicant also reiterated that, unlike meropenem alone, VABOMERETM is on-label indicated for the use in the treatment of a cUTI diagnosis. Several commenters believed that VABOMERETM may be substantially similar to other existing therapies. The applicant believed that CMS' application of the ``substantial similarity'' standards for newness as described in prior IPPS rulemakings, including aspects of CMS' discussion of these criteria in the FY 2019 IPPS/LTCH PPS proposed rule as applied to VABOMERETM, are restrictive and may impose unnecessarily narrow standards for newness that are not included in the statute or regulations. The applicant stated that, if applied as suggested in the proposed rule, CMS may not account for the realities and circumstances involved in developing and bringing a new therapy--particularly a new antibiotic--to the U.S. market. The applicant [[Page 41307]] suggested CMS apply its newness standards in a manner that recognizes the innovative nature and unique aspects of new technologies, like VABOMERETM, consistent with the text and spirit of the new technology add-on payment provisions. Other commenters stated that, given the recognized shortage of new antibiotics, the unique benefits of VABOMERETM should not be ignored because of substantial similarities to other medicines. Response: We appreciate the applicant's and commenters' input. We agree that VABOMERETM has a unique mechanism of action that is not similar to other existing technologies because it is a new class of beta-lactamase inhibitor that protects meropenem from degradation by certain enzymes such as carbapenamases. We agree that the addition of vaborbactam as a potent inhibitor against Class A and C serine beta- lactamases, particularly KPC, represents a new mechanism of action. After consideration of the public comments we received, we believe that VABOMERETM is not substantially similar to existing technologies and meets the newness criterion. With regard to the cost criterion, the applicant conducted the following analysis to demonstrate that the technology meets the cost criterion. In order to identify the range of MS-DRGs to which cases representing potential patients who may be eligible for treatment using VABOMERETM may map, the applicant used the Premier Research Database from 2nd Quarter 2015 to 4th Quarter 2016. According to the applicant, Premier is an electronic laboratory, pharmacy, and billing data repository that collects data from over 600 hospitals and captures nearly 20 percent of U.S. hospitalizations. The applicant's list of most common MS-DRGs is based on data regarding CRE from the Premier Research Database. According to the applicant, approximately 175 member hospitals also submit microbiology data, which allowed the applicant to identify specific pathogens such as CRE infections. Using the Premier Research Database, the applicant identified over 350 MS-DRGs containing data for 2,076 cases representing patients who had been hospitalized for CRE infections. The applicant used the top five most common MS- DRGs: MS-DRG 871 (Septicemia or Severe Sepsis without Mechanical Ventilation >96 Hours with MCC), MS-DRG 853 (Infectious and Parasitic Disease with O.R. Procedure with MCC), MS-DRG 870 (Septicemia or Severe Sepsis with Mechanical Ventilation >96 Hours), MS-DRG 872 (Septicemia or Severe Sepsis without Mechanical Ventilation >96 Hours without MCC), and MS-DRG 690 (Kidney and Urinary Tract Infections without MCC), to which 627 cases representing potential patients who may be eligible for treatment involving VABOMERETM, or approximately 30.2 percent of the total cases identified, mapped. The applicant reported that the resulting 627 cases from the identified top 5 MS-DRGs have an average case-weighted unstandardized charge per case of $74,815. In the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20301), we noted that, instead of using actual charges from the Premier Research Database, the applicant computed this amount based on the average case-weighted threshold amounts in Table 10 from the FY 2018 IPPS/LTCH PPS final rule. For the rest of the analysis, the applicant adjusted the average case-weighted threshold amounts (referred to above as the average case-weighted unstandardized charge per case) rather than the actual average case-weighted unstandardized charge per case from the Premier Research Database. According to the applicant, based on the Premier data, $1,999 is the mean antibiotic costs of treating patients hospitalized with CRE infections with current therapies. The applicant explained that it identified 69 different regimens that ranged from 1 to 4 drugs from a study conducted to understand the current management of patients diagnosed with CRE infections. Accordingly, the applicant estimated the removal of charges for a prior technology of $1,999. The applicant then standardized the charges. The applicant applied an inflation factor of 9.357 percent from the FY 2018 IPPS/LTCH PPS final rule (82 FR 38527) to inflate the charges. At the time of the development of the proposed rule, the applicant noted that it did not yet have sufficient charge data from hospitals and would work to supplement its application with the information once it was available. However, for purposes of calculating charges, the applicant used the average charge as the wholesale acquisition cost (WAC) price for a treatment duration of 14 days and added this amount to the average charge per case. Using this estimate, the applicant calculated the final inflated case-weighted standardized charge per case as $91,304, which exceeded the average case-weighted threshold amount of $74,815. Therefore, the applicant asserted that VABOMERETM met the cost criterion. In the proposed rule, we indicated we were concerned that, as noted earlier, instead of using actual charges from the Premier Research Database, the applicant computed the average case-weighted unstandardized charge per case based on the average case-weighted threshold amounts in Table 10 from the FY 2018 IPPS/LTCH PPS final rule. Because the applicant did not demonstrate that the average case- weighted standardized charge per case for VABOMERETM (using actual charges from the Premier Research Database) would exceed the average case-weighted threshold amounts in Table 10, we were unable to determine if the applicant met the cost criterion. We invited public comments on whether VABOMERETM met the cost criterion, including with respect to the concern regarding the applicant's analysis. Comment: The applicant addressed CMS' concern regarding the cost criterion and analysis and submitted a revised cost analysis in response. The applicant conducted a revised analysis using claims from the FY 2016 MedPAR to demonstrate that VABOMERETM meets the cost criterion. To identify potential cases representing patients who may be eligible for treatment involving VABOMERETM, the applicant identified 34 ICD-10-CM diagnosis codes from claims from the FY 2016 MedPAR specific to the anticipated VABOMERETM patient population. The applicant distinguished the 34 ICD-10-CM diagnosis codes by three different subsets, with Subset 1 based on 17 of the 34 ICD-10-CM diagnosis codes; Subset 2 based on 13 of the 34 ICD-10-CM diagnosis codes; and Subset 3 based on 8 of the 34 ICD-10-CM diagnosis codes. The applicant noted that the 8 ICD-10-CM diagnosis codes used in the Subset 3 analysis also are included in all three of the analyses, and the 13 ICD-10-CM diagnosis codes included in the Subset 2 analysis also are included among the 17 diagnosis codes used in the Subset 1 analysis. For each subset, the applicant conducted a cost analysis for 100 percent of the identified cases, 75 percent of the identified cases, the top 20 MS-DRGs to which potential cases would map, and the top 10 MS-DRGs to which potential cases would map. For each subset, the applicant performed the following: (1) Calculated the case-weighted unstandardized charge per case; (2) removed 100 percent of the drug charges from the relevant cases in order to conservatively estimate for charges for drugs that potentially may be replaced by VABOMERETM; (3) standardized the charges; (4) applied the 2- year inflation factor of 9.357 percent from the FY 2018 IPPS/LTCH PPS final rule (82 FR 38527); (5) added the charges for VABOMERETM (the [[Page 41308]] applicant calculated the charges for VABOMERETM by converting the costs of VABOMERETM to charges and dividing the costs by the national CCR of 0.194 for ``Drugs'' from the FY2018 IPPS/LTCH PPS final rule (82 FR 38103)); and (6) computed the inflated average case-weighted standardized charge per case and the average case-weighted threshold amount. The applicant stated that the cost of VABOMERETM is $165 per vial. The applicant indicated that a patient receives two vials per dose and three doses per day. Therefore, the per-day cost of VABOMERETM is $990 per patient. The duration of therapy, consistent with the Prescribing Information, is up to 14 days. Therefore, the applicant estimated that the cost of VABOMERETM to the hospital, per patient, is $13,860. The applicant believed that, based on limited data from the product's launch, approximately 80 percent of VABOMERETM's usage would be in the inpatient hospital setting, and approximately 20 percent of VABOMERETM's usage may take place outside of the inpatient hospital setting. Therefore, the applicant stated that the average number of days of VABOMERETM administration in the inpatient hospital setting is estimated at 80 percent of 14 days, or approximately 11.2 days. As a result, the applicant calculated that the total inpatient cost is $11,088 ($990 * 11.2 days), which was then converted to charges in the calculations above. The applicant stated that each subset demonstrated the average case-weighted standardized charge per case exceeded the average case- weighted threshold amount. Below are three tables, one for each subset, showing that the average case-weighted standardized charge per case exceeded the average case-weighted threshold amount. ---------------------------------------------------------------------------------------------------------------- 100 Percent of 75 Percent of Subset 1 cost analysis the identified the identified Top 20 Top 10 cases cases MS[dash]DRGs MS[dash]DRGs ---------------------------------------------------------------------------------------------------------------- Case[dash]Weighted Unstandardized Charge Per $66,978 $61,313 $54,894 $56,004 Case...........................................

After consideration of the public comment and revised cost analysis we received, we believe that VABOMERETM meets the cost criterion. With regard to the substantial clinical improvement criterion, the applicant believed that the results from the VABOMERETM clinical trials clearly establish that VABOMERETM represents a substantial clinical improvement for treatment of deadly, antibiotic resistant infections. Specifically, the applicant asserted that VABOMERETM offers a treatment option for a patient population unresponsive to, or ineligible for, currently available treatments, and the use of VABOMERETM significantly improves clinical outcomes for a patient population as compared to currently available treatments. The applicant provided the results of the Targeting Antibiotic Non-sensitive Gram-Negative Organisms (TANGO) I and II clinical trials to support its assertion. TANGO I \89\ was a prospective, randomized, double-blinded trial of VABOMERETM versus piperacillin-tazobactam in patients with cUTIs and acute pyelonephritis (A/P). TANGO I is also a noninferiority (NI) trial powered to evaluate the efficacy, safety, and tolerability of VABOMERETM compared to piperacillin-tazobactam in the treatment of cUTI, including AP, in adult patients. There were two primary endpoints for this study, one for the FDA, which was cure or improvement and microbiologic outcome of eradication at the end-of- treatment (EOT) (day 5 to 14) in the proportion of patients in the Microbiologic Evaluable Modified Intent-to-Treat (m-MITT) population who achieved overall success (clinical cure or improvement and eradication of baseline pathogen to <104 CFU/mL), and one for the European Medicines Agency (EMA), which was the proportion of patients in the co-primary m-MITT and Microbiologic Evaluable (ME) populations who achieve a microbiologic outcome of eradication (eradication of baseline pathogen to <103 CFU/mL) at the test-of-cure (TOC) visit (day 15 to 23). The trial enrolled 550 adult patients who were randomized 1:1 to receive [[Page 41309]] VABOMERETM as a 3-hour IV infusion every 8 hours, or piperacillin 4g-tazobactam 500 mg as a 30 minute IV infusion every 8 hours, for at least 5 days for the treatment of a cUTI. Therapy was set at a minimum of 5 days to fully assess the efficacy and safety of VABOMERETM. After a minimum of 5 days of IV therapy, patients could be switched to oral levofloxacin (500 mg once every 24 hours) to complete a total of 10-day treatment course (IV+oral), if they met pre-specified criteria. Treatment was allowed for up to 14 days, if clinically indicated. --------------------------------------------------------------------------- \89\ Vabomere Prescribing Information, Clinical Studies (August 2017), available at: https://www.accessdata.fda.gov/drugsatfda_docs/label/2017/209776lbl.pdf. --------------------------------------------------------------------------- Patient demographic and baseline characteristics were balanced between treatment groups in the m-MITT population. Approximately 93 percent of patients were Caucasian and 66 percent were females in both treatment groups. The mean age was 54 years old with 32 percent and 42 percent of the patients 65 years old and older in the VABOMERETM and piperacillin/tazobactam treatment groups, respectively. Mean body mass index was approximately 26.5 kg/m2 in both treatment groups. Concomitant bacteremia was identified in 12 (6 percent) and 15 (8 percent) of the patients at baseline in the VABOMERETM and piperacillin/tazobactam treatment groups, respectively. The proportion of patients who were diagnosed with diabetes mellitus at baseline was 17 percent and 19 percent in the VABOMERETM and piperacillin/tazobactam treatment groups, respectively. The majority of the patients (approximately 90 percent) were enrolled from Europe, and approximately 2 percent of the patients were enrolled from North America. Overall, in both treatment groups, 59 percent of the patients had pyelonephritis and 40 percent had a cUTI, with 21 percent and 19 percent of the patients having a non-removable and removable source of infection, respectively. Mean duration of IV treatment in both treatment groups was 8 days and mean total treatment duration (IV and oral) was 10 days; patients with baseline bacteremia could receive up to 14 days of therapy (IV and oral). Approximately 10 percent of the patients in each treatment group in the m-MITT population had a levofloxacin-resistant pathogen at baseline and received levofloxacin as the oral switch therapy. According to the applicant, this protocol violation may have impacted the assessment of the outcomes at the TOC visit. These patients were not excluded from the analysis of adverse reactions (headache, phlebitis, nausea, diarrhea, and others) occurring in 1 percent or more of the patients receiving VABOMERETM, as the decision to switch to oral levofloxacin was based on post-randomization factors. Regarding the FDA primary endpoint, the applicant stated the following: Overall success rate at the end of IV treatment (day 5 to 14) was 98.4 percent and 94 percent for the VABOMERETM and piperacillin/tazobactam treatment groups, respectively. The TOC--7 days post IV therapy was 76.5 percent (124 of 162 patients) for the VABOMERETM group and 73.2 percent (112 of 153 patients) for the piperacillin/tazobactam group. Despite being an NI trial, TANGO-I showed a statistically significant difference favoring VABOMERETM in the primary efficacy endpoint over piperacillin/tazobactam (a commonly used agent for gram-negative infections in U.S. hospitals). VABOMERETM demonstrated statistical superiority over piperacillin-tazobactam with overall success of 98.4 percent of patients treated with VABOMERETM in the TANGO-I clinical trial compared to 94.0 percent for patients treated with piperacillin/ tazobactam, with a treatment difference of 4.5 percent and 95 percent CI of (0.7 percent, 9.1 percent). Because the lower limit of the 95 percent CI is also greater than 0 percent, VABOMERETM was statistically superior to piperacillin/tazobactam. Because non-inferiority was demonstrated, then superiority was tested. Further, the applicant asserted that a non-inferiority design may have a ``superiority'' hypothesis imbedded within the study design that is appropriately tested using a non-inferiority design and statistical analysis. As such, according to the applicant, superiority trials concerning antibiotics are impractical and even unethical in many cases because one cannot randomize patients to receive inactive therapies. The applicant stated that it would be unethical to leave a patient with a severe infection without any treatment. The EMA endpoint of eradication rates at TOC were higher in the VABOMERETM group compared to the piperacillin/ tazobactam group in both the m-MITT (66.7 percent versus 57.7 percent) and ME (66.3 percent and 60.4 percent) populations; however, it was not a statistically significant improvement. In the proposed rule, we noted that the eradication rates of the EMA endpoint were not statistically significant. We invited public comments with respect to our concern as to whether the FDA endpoints demonstrating non-inferiority are statistically sufficient data to support that VABOMERETM is a substantial clinical improvement in the treatment of patients with a cUTI. In its application, the applicant offered data from the TANGO-I trial comparing VABOMERETM to piperacillin-tazobactam EOT/ TOC rates in the setting of cUTIs/AP, but in the proposed rule we stated that the applicant did not offer a comparison to other antibiotic treatments of cUTIs known to be effective against gram- negative uropathogens, specifically other carbapenems.\90\ In the proposed rule, we also noted that the study population is largely European (98 percent), and given the variable geographic distribution of antibiotic resistance we indicated we were concerned that the use of piperacillin/tazobactam as the comparator may have skewed the eradication rates in favor of VABOMERETM, or that the favorable results would not be applicable to patients in the United States. We invited public comments regarding the lack of a comparison to other antibiotic treatments of cUTIs known to be effective against gram-negative uropathogens, whether the comparator the applicant used in its trial studies may have skewed the eradication rates in favor of VABOMERETM, and if the favorable results would be applicable to patients in the United States to allow for sufficient information in evaluating substantial clinical improvement. --------------------------------------------------------------------------- \90\ Golan, Y., 2015, ``Empiric therapy for hospital-acquired, Gram-negative complicated intra-abdominal infection and complicated urinary tract infections: a systematic literature review of current and emerging treatment options,'' BMC Infectious Diseases, vol. 15, pp. 313. http://doi.org/10.1186/s12879-015-1054-1. --------------------------------------------------------------------------- In the proposed rule we noted that the applicant asserted that the TANGO II study \91\ of monotherapy with VABOMERETM compared to best available therapy (BAT) (salvage care of cocktails of toxic/ poorly efficacious last resort agents) for the treatment of CRE infections showed important differences in clinical outcomes, including reduced mortality, higher clinical cure at EOT and TOC, benefit in important patient subgroups of HABP/VABP, bacteremia, renal impairment, and immunocompromised and reduced AEs, particularly lower nephrotoxicity in the study group. TANGO II is a multi- [[Page 41310]] center, randomized, Phase III, open-label trial of patients with infections due to known or suspected CRE, including cUTI, AP, HABP/ VABP, bacteremia, or complicated intra-abdominal infection (cIAI). Eligible patients were randomized 2:1 to monotherapy with VABOMERETM or BAT for 7 to 14 days. There were no consensus BAT regimes, it could include (alone or in combination) a carbapenem, aminoglycoside, polymyxin B, colistin, tigecycline or ceftazidime- avibactam. --------------------------------------------------------------------------- \91\ Alexander, et al., ``CRE Infections: Results From a Retrospective Series and Implications for the Design of Prospective Clinical Trials,'' Open Forum Infectious Diseases. --------------------------------------------------------------------------- A total of 72 patients were enrolled in the TANGO II trial. Of these, 50 of the patients (69.4 percent) had a gram-negative baseline organism (m-MITT population), and 43 of the patients (59.7 percent) had a baseline CRE (mCRE-MITT population). Within the mCRE-MITT population, 20 of the patients had bacteremia, 15 of the patients had a cUTI/AP, 5 of the patients had HABP/VABP, and 3 of the patients had a cIAI. The most common baseline CRE pathogens were K. pneumoniae (86 percent) and Escherichia coli (7 percent). Cure rates of the mCRE-MITT population at EOT for VABOMERETM and BAT groups were 64.3 percent and 40 percent, respectively, TOC, 7 days after EOT, were 57.1 percent and 26.7 percent, respectively, 28-day mortality was 17.9 percent (5 of 28 patients) and 33.3 percent (5 of 15 patients), respectively. The applicant asserted that with further sensitivity analysis, taking into account prior antibiotic failures among the VABOMERETM study arm, the 28-day all-cause mortality rates were even lower among VABOMERETM versus BAT patients (5.3 percent (1 of 19 patients) versus 33.3 percent (5 of 15 patients). Additionally, in July 2017, randomization in the trial was stopped early following a recommendation by the TANGO II Data Safety Monitoring Board (DSMB) based on risk-benefit considerations that randomization of additional patients to the BAT comparator arm should not continue. According to the applicant, subgroup analyses of the TANGO II studies include an analysis of adverse events in which VABOMERETM compared to BAT demonstrated the following: VABOMERETM was associated with less severe treatment emergent adverse events of 13.3 percent versus 28 percent. VABOMERETM was less likely to be associated with a significant increase in creatinine 3 percent versus 26 percent. Efficacy results of the TANGO II trial cUTI/AP subgroup demonstrated VABOMERETM was associated with an overall success rate at EOT for the mCRE-MITT populations of 72 percent (8 of 11 patients) versus 50 percent (2 of 4 patients) and an overall success rate at TOC of 27.3 percent (3 of 7 patients) versus 50 percent (2 of 4 patients). In the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20303), we noted that many of the TANGO II trial outcomes showing improvements in the use of VABOMERETM over BAT are not statistically significant. We also noted that the TANGO II study included a small number of patients; the study population in the mCRE-MITT only included 43 patients. Additionally, the cUTI/AP subgroup analysis only included a total of 15 patients and did not show an increased overall success rate at TOC (27.3 percent versus 50 percent) over the BAT group. We invited public comments with respect to our concern as to whether the lack of statistically significant outcomes and the small number of study participants allows for enough information to evaluate substantial clinical improvement. We invited public comments on whether the VABOMERETM technology meets the substantial clinical improvement criterion, including with respect to the specific concerns we have raised. Comment: The applicant stated that VABOMERETM represents and has demonstrated a substantial clinical improvement over other existing available therapies. The applicant also stated that, in particular, the results from the TANGO I and TANGO II, Phase III clinical trials establish that VABOMERETM represents a ``substantial clinical improvement'' for treatment of deadly, antibiotic-resistant infections. The applicant reiterated the results of the TANGO I and TANGO II trials and noted the results show VABOMERETM had a statistically significant higher response rate than piperacillin/tazobactam in clinical cure and microbial eradication. The applicant stated that, in TANGO I, piperacillin- tazobactam was used as a comparator because it is very commonly used in U.S. hospitals to treat infections, including severe UTIs. The applicant indicated that, for example, as reflected in the VABOMERETM Prescribing Information, the results of the TANGO I demonstrate superiority as evidenced by the overall success rate at the end of IV treatment (day 5 to 14) at 98.4 percent and 94 percent for the VABOMERETM and piperacillin/tazobactam treatment groups, respectively, and the TOC--7 days post IV therapy at 76.5 percent (124 of 162 patients) for the VABOMERETM group and 73.2 percent (112 of 153 patients) for the piperacillin/tazobactam group. The applicant noted that, regarding non-inferiority and superiority data, the statutory and regulatory standards for new technology add-on payments do not preclude the relevance of non- inferiority data for purposes of demonstrating that a new therapy meets the ``substantial clinical improvement'' criterion. The applicant indicated that CMS has previously approved an application for new technology add-on payments and agreed that it represented a substantial clinical improvement over existing technologies on the basis of non- inferior data. The applicant further indicated that, with regard to the size of the study population for TANGO II, this study focused specifically on a patient population known to have or suspected of having CRE. The applicant further stated that, despite a concerted effort to search for patients with CRE infection and intensive pre-screening and screening activities across the globe, it took more than 2.5 years to enroll 77 patients. The applicant also noted that many other clinical studies in the context of new antibiotics development and other areas have involved similar or smaller cohorts of patients. According to the applicant, in the specific context of TANGO II, approximately 100 patients were pre-screened for each individual enrolled patient. The applicant stated that challenges are typical of the ``ultra-orphan'' world of antimicrobial development, where new treatments are needed, and pathogen-focused or resistance-focused clinical trials are crucial to accurately determine the efficacy of the treatment. The applicant further stated that unfortunately, study challenges (including difficulty consenting seriously-ill patients and their families, restricted entry criteria, exclusion for prior antibiotics, among others), along with a rare diagnosis, make larger trials with this life-threatening condition quite difficult to conduct. The applicant indicated that the patients enrolled in this study had a high incidence of underlying comorbidities and a high disease severity, with approximately 40 percent of the patients being immunocompromised and 75 percent with a Charlson Comorbidity Score >5. The applicant also noted appreciation that CMS recognized these challenges, particularly in the context of clinical trials for new antibiotic products that treat serious and life-threatening infections. The applicant believed that, for these reasons, the sample size used in the TANGO II trial does not undermine or diminish the significance of its results. The applicant indicated that the study focused specifically on [[Page 41311]] patients with known or suspected CRE and was powered specifically to test certain endpoints, which it demonstrated--and, notably--did so using VABOMERETM as a monotherapy. The applicant believed that this is distinct from other clinical trials and underscores the significance of the TANGO II results. The applicant further noted that the TANGO II trial demonstrated certain improved outcomes with such statistical significance that the independent data monitoring review board recommended early termination of the randomization in the trial to allow patients to cross over to the VABOMERETM arm instead of the BAT arm in the trial. One commenter agreed with CMS' concern that improved outcomes in some trials may not be statistically significant and that the small number of patients, and the lack of a comparison to other antibiotic treatments of cUTIs known to be effective against uropathogens may not support that VABOMERETM represents a substantial clinical improvement in the treatment of patients diagnosed with a cUTI. Response: We appreciate the commenter's input and the applicant's responses to our concerns. After consideration of the public comments we received, we believe that VABOMERETM offers a substantial clinical improvement for patients who have limited or no alternative treatment options because it is a new antibiotic that offers a treatment option for a patient population unresponsive to currently available treatments. Specifically, VABOMERETM is a novel, first-in-class beta-lactamase inhibitor helps to protect the meropenem from degradation by certain beta-lactamases, such as KPC. Additionally, results from the TANGO II study demonstrate better outcomes regarding 28-day all-cause mortality taking into account prior antibiotic failures (VABOMERETM patients (5.3 percent) versus BAT patients (33.3 percent), p=0.03), as well as decreases nephrotoxicity (VABOMERETM 11.1 percent versus BAT 24.0 percent). Therefore, based on the above, we believe that VABOMERETM represents a substantial clinical improvement. In summary, we have determined that VABOMERETM meets all of the criteria for approval of new technology add-on payments. Therefore, we approving new technology add-on payments for VABOMERETM for FY 2019. We note that, the applicant did not request approval for the use of a unique ICD-10-PCS procedure code for VABOMERETM for FY 2019. As a result, hospitals will be unable to uniquely identify the use of VABOMERETM on an inpatient claim using the typical coding of an ICD-10-PCS procedure code. In the FY 2013 IPPS/LTCH PPS final rule (77 FR 53352), with regard to the oral drug DIFICIDTM, we revised our policy to allow for the use of an alternative code set to identify oral medications where no inpatient procedure is associated for the purposes of new technology add-on payments. We established the use of a National Drug Code (NDC) as the alternative code set for this purpose and described our rationale for this particular code set. This change was effective for payments for discharges occurring on or after October 1, 2012. We acknowledge that VABOMERETM is not an oral drug and is administered by IV infusion, but it is the first approved new technology aside from an oral drug with no uniquely assigned inpatient procedure code. We, therefore, believe that the circumstances with respect to the identification of eligible cases using VABOMERETM are similar to those addressed in the FY 2013 IPPS/LTCH PPS final rule with regard to DIFICIDTM because we do not have current ICD-10-PCS code(s) to uniquely identify the use of VABOMERETM to make the new technology add-on payment. Because we have determined that VABOMERETM has met all of the new technology add-on payment criteria and cases involving the use of VABOMERETM will be eligible for such payments for FY 2019, we need to use an alternative coding method to identify these cases and make the new technology add-on payment for use of VABOMERETM in FY 2019. Therefore, similar to the policy in the FY 2013 IPPS/LTCH PPS final rule, in the place of an ICD-10-PCS procedure code, FY 2019 cases involving the use of VABOMERETM that are eligible for the FY 2019 new technology add-on payments will be identified by the NDC of 65293-009-01 (VABOMERETM Meropenem-Vaborbactam Vial). Providers must code the NDC in data element LIN03 of the 837i Health Care Claim Institutional form in order to receive the new technology add-on payment for procedures involving the use of VABOMERETM. The applicant may request approval for a unique ICD-10-PCS procedure code for FY 2020. As discussed above, according to the applicant, the cost of VABOMERETM is $165 per vial. A patient receives two vials per dose and three doses per day. Therefore, the per-day cost of VABOMERETM is $990 per patient. The duration of therapy, consistent with the Prescribing Information, is up to 14 days. Therefore, the estimated cost of VABOMERETM to the hospital, per patient, is $13,860. Based on the limited data from the product's launch, approximately 80 percent of VABOMERETM's usage would be in the inpatient hospital setting, and approximately 20 percent of VABOMERETM's usage may take place outside of the inpatient hospital setting. Therefore, the average number of days of VABOMERETM administration in the inpatient hospital setting is estimated at 80 percent of 14 days, or approximately 11.2 days. As a result, the total inpatient cost for VABOMERETM is $11,088 ($990 * 11.2 days). Under Sec. 412.88(a)(2), we limit new technology add-on payments to the lesser of 50 percent of the average cost of the technology, or 50 percent of the costs in excess of the MS-DRG payment for the case. As a result, the maximum new technology add-on payment for a case involving the use of VABOMERETM is $5,544 for FY 2019. d. remed[emacr][supreg] System Respicardia, Inc. submitted an application for new technology add- on payments for the remed[emacr][supreg] System for FY 2019. According to the applicant, the remed[emacr][supreg] System is indicated for use as a transvenous phrenic nerve stimulator in the treatment of adult patients who have been diagnosed with moderate to severe central sleep apnea. The remed[emacr][supreg] System consists of an implantable pulse generator, and a stimulation and sensing lead. The pulse generator is placed under the skin, in either the right or left side of the chest, and it functions to monitor the patient's respiratory signals. A transvenous lead for unilateral stimulation of the phrenic nerve is placed either in the left pericardiophrenic vein or the right brachiocephalic vein, and a second lead to sense respiration is placed in the azygos vein. Both leads, in combination with the pulse generator, function to sense respiration and, when appropriate, generate an electrical stimulation to the left or right phrenic nerve to restore regular breathing patterns. The applicant describes central sleep apnea (CSA) as a chronic respiratory disorder characterized by fluctuations in respiratory drive, resulting in the cessation of respiratory muscle activity and airflow during sleep.\92\ The applicant reported that CSA, as a primary disease, has a low prevalence in the United States population; and it is [[Page 41312]] more likely to occur in those individuals who have cardiovascular disease, heart failure, atrial fibrillation, stroke, or chronic opioid usage. The apneic episodes which occur in patients with CSA cause hypoxia, increased blood pressure, increased preload and afterload, and promotes myocardial ischemia and arrhythmias. In addition, CSA ``enhances oxidative stress, causing endothelial dysfunction, inflammation, and activation of neurohormonal systems, which contribute to progression of underlying diseases.'' \93\ --------------------------------------------------------------------------- \92\ Jagielski, D., Ponikowski, P., Augostini, R., Kolodziej, A., Khayat, R., Abraham, W.T., 2016, ``Transvenous Stimulation of the Phrenic Nerve for the Treatment of Central Sleep Apnoea: 12 months' experience with the remede[reg] Ssystem,'' European Journal of Heart Failure, pp. 1-8. \93\ Costanzo, M.R., Ponikowski, P., Javaheri, S., Augostini, R., Goldberg, L., Holcomb, R., Abraham, W.T., ``Transvenous Neurostimulation for Centra Sleep Apnoea: A randomised controlled trial,'' Lacet, 2016, vol. 388, pp. 974-982. --------------------------------------------------------------------------- According to the applicant, prior to the introduction of the remed[emacr][supreg] System, typical treatments for CSA took the form of positive airway pressure devices. Positive airway pressure devices, such as continuous positive airway pressure (CPAP), have previously been used to treat patients diagnosed with obstructive sleep apnea. Positive airway devices deliver constant pressurized air via a mask worn over the mouth and nose, or nose alone. For this reason, positive airway devices may only function when the patient wears the necessary mask. Similar to CPAP, adaptive servo-ventilation (ASV) provides noninvasive respiratory assistance with expiratory positive airway pressure. However, ASV adds servo-controlled inspiratory pressure, as well, in an effort to maintain airway patency.\94\ --------------------------------------------------------------------------- \94\ Cowie, M.R., Woehrle, H., Wegscheider, K., Andergmann, C., d'Ortho, M.P., Erdmann, E., Teschler, H., ``Adaptive Servo- Ventilation for Central Sleep Apneain Systolic Heart Failure,'' N Eng Jour of Med, 2015, pp. 1-11. --------------------------------------------------------------------------- On October 6, 2017, the remed[emacr][supreg] System was approved by the FDA as an implantable phrenic nerve stimulator indicated for the use in the treatment of adult patients who have been diagnosed with moderate to severe CSA. The device was available commercially upon FDA approval. Therefore, the newness period for the remed[emacr][supreg] System is considered to begin on October 6, 2017. The applicant has indicated that the device also is designed to restore regular breathing patterns in the treatment of CSA in patients who also have been diagnosed with heart failure. The applicant was approved for two unique ICD-10-PCS procedure codes for the placement of the leads: 05H33MZ (Insertion of neurostimulator lead into right innominate (brachiocephalic) vein) and 05H03MZ (Insertion of neurostimulator lead into azygos vein), effective October 1, 2016. The applicant indicated that implantation of the pulse generator is currently reported using ICD-10-PCS procedure code 0JH60DZ (Insertion of multiple array stimulator generator into chest subcutaneous tissue). As discussed above, if a technology meets all three of the substantial similarity criteria, it would be considered substantially similar to an existing technology and would not be considered ``new'' for the purposes of new technology add-on payments. As stated in the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20309), with regard to the first criterion, whether a product uses the same or a similar mechanism of action to achieve a therapeutic outcome, according to the applicant, the remed[emacr][supreg] System provides stimulation to nerves to stimulate breathing. Typical treatments for hyperventilation CSA include supplemental oxygen and CPAP. Mechanical ventilation also has been used to maintain a patent airway. The applicant asserted that the remed[emacr][supreg] System is a neurostimulation device resulting in negative airway pressure, whereas devices such as CPAP and ASV utilize positive airway pressure. With respect to the second criterion, whether a product is assigned to the same or a different MS-DRG, the applicant stated that the remed[emacr][supreg] System is assigned to MS-DRGs 040 (Peripheral, Cranial Nerve and Other Nervous System Procedures with MCC), 041 (Peripheral, Cranial Nerve and Other Nervous System Procedures with CC or Peripheral Neurostimulator), and 042 (Peripheral, Cranial Nerve and Other Nervous System Procedures without CC/MCC). The current procedures for the treatment options of CPAP and ASV are not assigned to these MS- DRGs. With respect to the third criterion, whether the new use of the technology involves the treatment of the same or similar type of disease and the same or similar patient population, according to the applicant, the remed[emacr][supreg] System is indicated for the use as a transvenous unilateral phrenic nerve stimulator in the treatment of adult patients who have been diagnosed with moderate to severe CSA. The applicant stated that the remed[emacr][supreg] System reduces the negative symptoms associated with CSA, particularly among patients who have been diagnosed with heart failure. The applicant asserted that patients who have been diagnosed with heart failure are particularly negatively affected by CSA and currently available CSA treatment options of CPAP and ASV. According to the applicant, the currently available treatment options, CPAP and ASV, have been found to have worsened mortality and morbidity outcomes for patients who have been diagnosed with both CSA and heart failure. Specifically, ASV is currently contraindicated in the treatment of CSA in patients who have been diagnosed with heart failure. The applicant also suggested that the remed[emacr][supreg] System is particularly suited for the treatment of CSA in patients who also have been diagnosed with heart failure. In the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20310), we stated we were concerned that, while the remed[emacr][supreg] System may be beneficial to patients who have been diagnosed with both CSA and heart failure, the FDA-approved indication is for use in the treatment of adult patients who have been diagnosed with moderate to severe CSA. We noted that the applicant's clinical analyses and data results related to patients who specifically were diagnosed with CSA and heart failure. We invited public comments on whether the remed[emacr][supreg] System meets the newness criterion. Comment: The applicant stated that the remed[emacr][supreg] System uses a different mechanism of action because neurostimulation of the phrenic nerve to treat patients who have been diagnosed with CSA is a new concept, both, in terms of its mechanism of action and approach. The applicant explained that utilizing small electrical pulses delivered to the phrenic nerve via a transvenous lead helps restore a more normal breathing pattern and indicated that there are no other FDA-approved CSA therapies that either utilize transvenous neurostimulation or generate negative pressure to treat patients who have been diagnosed with CSA. The applicant explained that currently, cases representing Medicare patients who have been admitted to the hospital with a diagnosis of CSA to receive treatment map to a wide array of MS-DRGs. However, the applicant believed that cases representing patients eligible for treatment involving the remed[emacr][supreg] System would be assigned to a different MS-DRG than cases representing patients treated using standard treatment options, including CPAP or ASV. The applicant further explained that, based on an analysis of FY 2018 MedPAR data, claims including a diagnosis of CSA mapped to 458 MS-DRGs with no single MS-DRG representing more than 4.5 percent of the total claims. The applicant believed this variant assignment of cases representing patients who have been diagnosed with CSA and received treatment is likely due to the fact that [[Page 41313]] the vast majority of claims in the MedPAR data included the CSA diagnosis as a secondary or tertiary diagnosis reported on the claim. The applicant indicated that cases representing patients receiving treatment involving the remed[emacr][supreg] System with CSA as a primary diagnosis would typically be assigned to MS-DRGs 040 or 041. Several other commenters also supported approval of new technology add-on payments for the remed[emacr][supreg] System, and asserted that the neurostimulation of the phrenic nerve is a different mechanism of action. The commenters indicated that they believed positive airway pressure (PAP) treatment is inferior to phrenic nerve stimulation because of patient intolerability, a lack of evidence in support of the success of PAP treatment in this population, or evidence showing that PAP such as ASV being contraindicated in the treatment of patients who have been diagnosed with CSA and heart failure. Another commenter agreed with the applicant, and stated that the remed[emacr][supreg] System's mechanism of action to deliver treatment, the neurostimulation of the phrenic nerve, is a new treatment approach that has never previously been used. Response: We appreciate the commenters' support and the applicant's further analysis and explanation regarding why the remed[emacr][supreg] System is not substantially similar to other currently available treatment options, as well as the input provided by the commenters. Based on review of the comments, we agree that utilization of the neurostimulation of the phrenic nerve, as performed by the remed[emacr][supreg] System, is a different mechanism of action and that cases representing patients receiving treatment involving the use of the remed[emacr][supreg] System would be assigned to a different MS- DRG than currently available treatment options. Therefore, we believe that the remed[emacr][supreg] System is not substantially similar to any other existing technology. We also note that the applicant provided additional information regarding patients who have been diagnosed with CSA, without a diagnosis of heart failure, and we considered this additional information in our evaluation of the application. After consideration of the public comments we received, for the reasons discussed, we believe that the remed[emacr][supreg] System is not substantially similar to any existing technology and it meets the newness criterion. Comment: The applicant stated that the remed[emacr][supreg] received FDA approval on October 6, 2017. However, the applicant noted that the first implant procedure was completed on February 01, 2018. Therefore, the applicant believed that the newness period should begin on February 01, 2018, rather than the FDA approval date. Response: As we discuss in section II.H.4. and in our discussion of Voraxaze included in the FY 2013 IPPS/LTCH PPS final rule (77 FR 53348), generally, our policy is to begin the newness period on the date of FDA approval or clearance or, if later, the date of availability of the product on the U.S. market. However, the applicant did not provide additional information to explain why there was a delay from the time of FDA approval until the completion of the first implant procedure to establish a different date of availability. Without additional information, we continue to believe that the newness period for the remed[emacr][supreg] System begins on October 6, 2017. We may consider any further information that may be provided regarding the date of availability in future rulemaking. With regard to the cost criterion, the applicant provided the following analysis to demonstrate that the technology meets the cost criterion. The applicant identified cases representing potential patients who may be eligible for treatment involving the remed[emacr][supreg] System within MS-DRGs 040, 041, and 042. Using the Standard Analytical File (SAF) Limited Data Set (MedPAR) for FY 2015, the applicant included all claims for the previously stated MS-DRGs for its cost threshold calculation. The applicant stated that typically claims are selected based on specific ICD-10-PCS parameters, however this is a new technology for which no ICD-10-PCS procedure code and ICD-10-CM diagnosis code combination exists. Therefore, all claims for the selected MS-DRGs were included in the cost threshold analysis. This process resulted in 4,462 cases representing potential patients who may be eligible for treatment involving the remed[emacr][supreg] System assigned to MS-DRG 040; 5,309 cases representing potential patients who may be eligible for treatment involving the remed[emacr][supreg] System assigned to MS-DRG 041; and 2,178 cases representing potential patients who may be eligible for treatment involving the remed[emacr][supreg] System assigned to MS-DRG 042, for a total of 11,949 cases. Using the 11,949 identified cases, the applicant determined that the average unstandardized case-weighted charge per case was $85,357. Using the FY 2015 MedPAR dataset to identify the total mean charges for revenue code 0278, the applicant removed charges associated with the current treatment options for each MS-DRG as follows: $9,153.83 for MS- DRG 040; $12,762.31 for MS-DRG 041; and $21,547.73 for MS-DRG 042. The applicant anticipated that no other related charges would be eliminated or replaced. The applicant then standardized the charges and applied a 2-year inflation factor of 1.104055 obtained from the FY 2018 IPPS/LTCH PPS final rule (82 FR 38524). The applicant then added charges for the new technology to the inflated average case-weighted standardized charges per case. No other related charges were added to the cases. The applicant calculated a final inflated average case-weighted standardized charge per case of $175,329 and a Table 10 average case- weighted threshold amount of $78,399. Because the final inflated average case-weighted standardized charge per case exceeded the average case-weighted threshold amount, the applicant maintained that the technology met the cost criterion. With regard to the analysis above, in the proposed rule, we stated that we were concerned that all cases in MS-DRGs 040, 041, and 042 were used in the analysis. We further stated that we were unsure if all of these cases represent patients that may be truly eligible for treatment involving the remed[emacr][supreg] System. We invited public comments on whether the remed[emacr][supreg] System meets the cost criterion. Comment: In response to our concern presented in the FY 2019 IPPS/ LTCH PPS proposed rule, the applicant submitted a revised analysis with regard to the cost criterion. In its revised cost calculations, the applicant searched the FY 2016 MedPAR data for cases reporting an ICD- 10-CM procedure code for the insertion of an array stimulator generator, in combination with a neurostimulator lead. Below is a table listing the codes searched by the applicant. ------------------------------------------------------------------------ ICD-10-PCS code Description (array stimulator generator) ------------------------------------------------------------------------ 0JH60BZ...................

The applicant removed 100 percent of the charges associated with the services provided in connection with the prior technology. The applicant then standardized the charges and inflated the charges by an inflation factor of 9.36 percent, which resulted in an inflated average case-weighted standardized charge per case of $61,426. According to the applicant, the cost of the remed[emacr][supreg] System is $34,500. The applicant converted the costs of the technology to charges by dividing the costs by the national CCR of 0.332 for ``Implantable Devices'' from the FY 2018 IPPS/LTCH PPS final rule. This resulted in $103,916 in estimated hospital charges for the new technology, which were added to the inflated standardized charges per case. The final inflated average case-weighted standardized charge per case is $165,342, which is $87,877 more than the Table 10 average case-weighted threshold amount of $77,465. Therefore, the applicant maintained that it meets the cost criterion. Response: We appreciate the applicant's submission of revised cost calculations in response to our concerns. After consideration of the additional information provided by the applicant, we agree that the remed[emacr][supreg] System meets the cost criterion. With respect to the substantial clinical improvement criterion, the applicant asserted that the remed[emacr][supreg] System meets the substantial clinical improvement criterion. The applicant stated that the remed[emacr][supreg] System offers a treatment option for a patient population unresponsive to, or ineligible for, treatment involving currently available options. According to the applicant, patients who have been diagnosed with CSA have no other available treatment options than the remed[emacr][supreg] System. The applicant stated that published studies on both CPAP and ASV have proven that primary endpoints have not been met for treating patients who have been diagnosed with CSA. In addition, according to the ASV study, there was an increase in cardiovascular mortality. According to the applicant, the remed[emacr][supreg] System will prove to be a better treatment for the negative effects associated with CSA in patients who have been diagnosed with heart failure, such as cardiovascular insults resulting from sympathetic nervous system [[Page 41315]] activation, pulmonary hypertension, and arrhythmias, which ultimately contribute to the downward cycle of heart failure,\95\ when compared to the currently available treatment options. The applicant also indicated that prior studies have assessed CPAP and ASV as options for the treatment of diagnoses of CSA primarily in patients who have been diagnosed with heart failure. --------------------------------------------------------------------------- \95\ Abraham, W., Jagielski, D., Oldenburg, O., Augostini, R., Kreuger, S., Kolodziej, A., Ponikowski, P., ``Phrenic Nerve Stimulation for the Treatment of Central Sleep Apnea,'' JACC: Heart Failure, 2015, vol. 3(5), pp. 360-369. --------------------------------------------------------------------------- The applicant shared the results from two studies concerning the effects of positive airway pressure ventilation treatment: The Canadian Continuous Positive Airway Pressure for Patients with Central Sleep Apnea and Heart Failure trial found that, while CPAP managed the negative symptoms of CSA, such as improved nocturnal oxygenation, increased ejection fraction, lower norepinephrine levels, and increased walking distance, it did not affect overall patient survival; \96\ and --------------------------------------------------------------------------- \96\ Bradley, T.D., Logan, A.G., Kimoff, R.J., Series, F., Morrison, D., Ferguson, K., Phil, D., 2005, ``Continous Positive Airway Pressure for Central Sleep Apnea and Heart Failure,'' N Eng Jour of Med, vol. 353(19), pp. 2025-2033. --------------------------------------------------------------------------- In a randomized trial of 1,325 patients who had been diagnosed with heart failure who received treatment with ASV plus standard treatment or standard treatment alone, ASV was found to increase all-cause and cardiovascular mortality as compared to the control treatment.\97\ --------------------------------------------------------------------------- \97\ Cowie, M.R., Woehrle, H., Wegscheider, K., Andergmann, C., d'Ortho, M.-P., Erdmann, E., Teschler, H., ``Adaptive Servo- Ventilation for Central Sleep Apneain Systolic Heart Failure,'' N Eng Jour of Med, 2015, pp. 1-11. --------------------------------------------------------------------------- The applicant also stated that published literature indicates that currently available treatment options do not meet primary endpoints with concern to the treatment of CSA; patients treated with ASV experienced an increased likelihood of mortality,\98\ and patients treated with CPAP experienced alleviation of symptoms, but no change in survival.\99\ The applicant provided further research, which suggested that a primary drawback of CPAP in the treatment of diagnoses of CSA is a lack of patient adherence to therapy.\100\ --------------------------------------------------------------------------- \98\ Ibid. \99\ Bradley, T.D., Logan, A.G., Kimoff, R.J., Series, F., Morrison, D., Ferguson, K., Phil, D., 2005, ``Continous Positive Airway Pressure for Central Sleep Apnea and Heart Failure,'' N Engl Jour of Med, vol. 353(19), pp. 2025-2033. \100\ Ponikowski, P., Javaheri, S., Michalkiewicz, D., Bart, B.A., Czarnecka, D., Jastrzebski, M., Abraham, W.T., ``Transvenous Phrenic Nerve Stimulation for the Treatment of Central Sleep Apnoea in Heart Failure,'' European Heart Journal, 2012, vol. 33, pp. 889- 894. --------------------------------------------------------------------------- The applicant also stated that the remed[emacr][supreg] System represents a substantial clinical improvement over existing technologies because of the reduction in the number of future hospitalizations, few device-related complications, and improvement in CSA symptoms and quality of life. Specifically, the applicant stated that the clinical data has shown a statistically significant reduction in Apnea-hypopnea index (AHI), improvement in quality of life, and significantly improved Minnesota Living with Heart Failure Questionnaire score. In addition, the applicant indicated that study results showed the remed[emacr][supreg] System demonstrated an acceptable safety profile, and there was a trend toward fewer heart failure hospitalizations. The applicant provided six published articles as evidence. All six articles were prospective studies. In three of the six studies, the majority of patients studied had been diagnosed with CSA with a heart failure comorbidity, while the remaining three studies only studied patients who had been diagnosed with CSA with a heart failure comorbidity. The first study \101\ assessed the treatment of patients who had been diagnosed with CSA in addition to heart failure. According to the applicant, as referenced in the results of the published study, Ponikowski, et al., assessed the treatment effects of 16 of 31 enrolled patients with evidence of CSA within 6 months prior to enrollment who met inclusion criteria (apnea-hypopnea index of greater than or equal to 15 and a central apnea index of greater than or equal to 5) and who did not meet exclusion criteria (a baseline oxygen saturation of less than 90 percent, being on supplemental oxygen, having evidence of phrenic nerve palsy, having had severe chronic obstructive pulmonary disease (COPD), having hard angina or a myocardial infarction in the past 3 months, being pacemaker dependent, or having inadequate capture of the phrenic nerve during neurostimulation). Of the 16 patients whose treatment was assessed, all had various classifications of heart failure diagnoses: 3 (18.8 percent) were classified as class I on the New York Heart Association classification scale (No limitation of physical activity. Ordinary physical activity does not cause undue fatigue, palpitation, dyspnea (shortness of breath)); 8 (50 percent) were classified as a class II (Slight limitation of physical activity. Comfortable at rest. Ordinary physical activity results in fatigue, palpitation, dyspnea (shortness of breath)); and 5 (31.3 percent) were classified as class III (Marked limitation of physical activity. Comfortable at rest. Less than ordinary activity causes fatigue, palpitation, or dyspnea).\102\ After successful surgical implantation of a temporary transvenous lead for unilateral phrenic nerve stimulation, patients underwent a control night without nerve stimulation and a therapy night with stimulation, while undergoing polysomnographic (PSG) testing. Comparison of both nights was performed. --------------------------------------------------------------------------- \101\ Ponikowski, P., Javaheri, S., Michalkiewicz, D., Bart, B.A., Czarnecka, D., Jastrzebski, M., Abraham, W.T., ``Transvenous Phrenic Nerve Stimulation for the Treatment of Central Sleep Apnoea in Heart Failure,'' European Heart Journal, 2012, vol. 33, pp. 889- 894. \102\ American Heart Association: ``Classes of Heart Failure,'' May 8, 2017. Available at: http://www.heart.org/HEARTORG/Conditions/HeartFailure/AboutHeartFailure/Classes-of-Heart-Failure_UCM_306328_Article.jsp#.WmE2rlWnGUk. --------------------------------------------------------------------------- According to the applicant, some improvements of CSA symptoms were identified in statistical analyses. Sleep time and efficacy were not statistically significantly different for control night and therapy night, with median sleep times of 236 minutes and 245 minutes and sleep efficacy of 78 percent and 71 percent, respectively. There were no statistical differences across categorical time spent in each sleep stage (for example, N1, N2, N3, and REM) between control and therapy nights. The average respiratory rate and hypopnea index did not differ statistically across nights. Marginal positive statistical differences occurred between control and therapy nights for the baseline oxygen saturation median values (95 and 96 respectively) and obstructive apnea index (OAI) (1 and 4, respectively). Beneficial statistically significant differences occurred from control to therapy nights for the average heart rate (71 to 70, respectively), arousal index events per hour (32 to 12, respectively), apnea-hypopnea index (AHI) (45 to 23, respectively), central apnea index (CAI) (27 to 1, respectively), and oxygen desaturation index of 4 percent (ODI = 4 percent) (31 to 14, respectively). Two adverse events were noted: (1) Lead tip thrombus noted when lead was removed; the patient was anticoagulated without central nervous system sequelae; and (2) an episode of ventricular tachycardia upon lead placement and before stimulation was initiated. The episode was successfully treated by defibrillation of the patient's implanted ICD. Neither adverse event was directly related to the phrenic nerve stimulation therapy. [[Page 41316]] The second study \103\ was a prospective, multi-center, nonrandomized study that followed patients diagnosed with CSA and other underlying comorbidities. According to the applicant, as referenced in the results of the published study, Abraham, et al., 49 of the 57 enrolled patients who were followed indicated a primary endpoint of a reduction of AHI with secondary endpoints of feasibility and safety of the therapy. Patients were included if they had an AHI of 20 or greater and apneic events that were related to CSA. Among the study patient population, 79 percent had diagnoses of heart failure, 2 percent had diagnoses of atrial fibrillation, 13 percent had other cardiac etiology diagnoses, and the remainder of patients had other cardiac unrelated etiology diagnoses. Exclusion criteria were similar to the previous study (that is, (Ponikowski P., 2012)), with the addition of a creatinine of greater than 2.5 mg/dl. After implantation of the remed[emacr][supreg] System, patients were assessed at baseline, 3 months (n=47) and 6 months (n=44) on relevant measures. At 3 months, statistically nonsignificant results occurred for the OAI and hypopnea index (HI) measures. The remainder of the measures showed statistically significant differences from baseline to 3 months: AHI with a -27.1 episodes per hour of sleep difference; CAI with a -23.4 episodes per hour of sleep difference; MAI with a -3 episodes per hour of sleep difference; ODI = 4 percent with a -23.7 difference; arousal index with -12.5 episodes per hour of sleep difference; sleep efficiency with a 8.4 percent increase; and REM sleep with a 4.5 percent increase. Similarly, among those assessed at 6 months, statistically significant improvements on all measures were achieved, including OAI and HI. Regarding safety, a data safety monitoring board (DSMB) adjudicated and found the following 3 of 47 patients (6 percent) as having serious adverse events (SAE) related to the device, implantation procedure or therapy. None of the DSMB adjudicated SAEs was due to lead dislodgement. Two SAEs of hematoma or headache were related to the implantation procedure and occurred as single events in two patients. A single patient experienced atypical chest discomfort during the first night of stimulation, but on reinitiation of therapy on the second night no further discomfort occurred. --------------------------------------------------------------------------- \103\ Abraham, W., Jagielski, D., Oldenburg, O., Augostini, R., Kreuger, S., Kolodziej, A., Ponikowski, P., ``Phrenic Nerve Stimulation for the Treatment of Central Sleep Apnea,'' JACC: Heart Failure, 2015, vol. 3(5), pp. 360-369. --------------------------------------------------------------------------- The third study \104\ assessed the safety and feasibility of phrenic nerve stimulation for 6 monthly follow-ups of 8 patients diagnosed with heart failure with CSA. Of the eight patients assessed, one was lost to follow-up and one died from pneumonia. According to the applicant, as referenced in the results in the published study, Zheng, et al. (2015), no unanticipated serious adverse events were found to be related to the therapy; in one patient, a lead became dislodged and subsequently successfully repositioned. Three patients reported improved sleep quality, and all patients reported increased energy. A reduction in sleep apneic events and decreases in AHI and CAI were related to application of the treatment. Gradual increases to the 6- minute walking time occurred through the study. --------------------------------------------------------------------------- \104\ Zhang, X., Ding, N., Ni, B., Yang, B., Wang, H., & Zhang, S.J., ``Satefy and Feasibility of Chronic Transvenous Phrenic Nerve Stimulation for Treatment of Central Sleep Apnea in Heart Failure Patients,'' The Clinical Respiratory Journal, 2015, pp. 1-9. --------------------------------------------------------------------------- The fourth study \105\ extended the previous Phase I study \106\ from 6 months to 12 months, and included only 41 of the original 49 patients continuing in the study. Of the 57 patients enrolled at the time of the Phase I study, 41 were evaluated at the 12-month follow-up. Of the 41 patients examined at 12 months, 78 percent had diagnoses of CSA related to heart failure, 2 percent had diagnoses of atrial fibrillation with related CSA, 12 percent had diagnoses of CSA related to other cardiac etiology diagnoses, and the remainder of patients had diagnoses of CSA related to other noncardiac etiology diagnoses. At 12 months, 6 sleep parameters remained statistically different and 3 were no longer statistically significant. The HI, OAI, and arousal indexes were no longer statistically significantly different from baseline values. A new parameter, time spent with peripheral capillary oxygen saturation (SpO2) below 90 percent was not statistically different at 12 months (31.4 minutes) compared to baseline (38.2 minutes). The remaining 6 parameters showed maintenance of improvements at the 12- month time point as compared to the baseline: AHI from 49.9 to 27.5 events per hour; CAI from 28.2 to 6.0 events per hour; MAI from 3.0 to 0.5 events per hour; ODI = 4 percent from 46.1 to 26.9 events per hour; sleep efficiency from 69.3 percent to 75.6 percent; and REM sleep from 11.4 percent to 17.1 percent. At the 3-month, 6-month, and 12-month time points, patient quality of life was assessed to be 70.8 percent, 75.6 percent, and 83.0 percent, respectively, indicating that patients experienced mild, moderate, or marked improvement. Seventeen patients were followed at 18 months with statistical differences from baseline for AHI and CAI. Three patients died over the 12-month follow-up period: 2 Died of end-stage heart failure and 1 died from sudden cardiac death. All three deaths were adjudicated by the DSMB and none were related to the procedure or to phrenic nerve stimulation therapy. Five patients were found to have related serious adverse events over the 12-month study time. Three events were previously described in the results referenced in the published study, Abraham, et al., and an additional 2 SAEs occurred during the 12-month follow-up. One patient experienced impending pocket perforation resulting in pocket revision, and another patient experienced lead failure. --------------------------------------------------------------------------- \105\ Jagielski, D., Ponikowski, P., Augostini, R., Kolodziej, A., Khayat, R., & Abraham, W.T., ``Transvenous Stimulation of the Phrenic Nerve for the Treatment of Central Sleep Apnoea: 12 months' experience with the remede[supreg]system,'' European Journal of Heart Failure, 2016, pp. 1-8. \106\ Abraham, W., Jagielski, D., Oldenburg, O., Augostini, R., Kreuger, S., Kolodziej, A., Ponikowski, P., 2015, ``Phrenic Nerve Stimulation for the Treatment of Central Sleep Apnea,'' JACC: Heart Failure, 2015, vol. 3(5), pp. 360-369. --------------------------------------------------------------------------- The fifth study \107\ was a randomized control trial with a primary outcome of achieving a reduction in AHI of 50 percent or greater from baseline to 6 months enrolling 151 patients with the neurostimulation treatment (n=73) and no stimulation control (n=78). Of the total sample, 96 (64 percent) of the patients had been diagnosed with heart failure; 48 (66 percent) of the treated patients had been diagnosed with heart failure, and 48 (62 percent) of the control patients had been diagnosed with heart failure. Sixty-four (42 percent) of all of the patients included in the study had been diagnosed with atrial fibrillation and 84 (56 percent) had been diagnosed with coronary artery disease. All of the patients had been treated with the remed[emacr][supreg] System device implanted; the system was activated in the treatment group during the first month. ``Over about 12 weeks, stimulation was gradually increased in the treatment group until diaphragmatic capture was consistently achieved without disrupting sleep.'' \108\ While patients and physicians were unblinded, the polysomnography core laboratory remained blinded. The per- [[Page 41317]] protocol population from which statistical comparisons were made is 58 patients treated with the remed[emacr][supreg] System and 73 patients in the control group. The authors appropriately controlled for Type I errors (false positives), which arise from performing multiple tests. Thirty-five treated patients and 8 control patients met the primary end point, the number of patients with a 50 percent or greater reduction in AHI from baseline; the difference of 41 percent is statistically significant. All seven of the secondary endpoints were assessed and found to have statistically significant difference in change from baseline between groups at the 6-month follow-up after controlling for multiple comparisons: CAI of -22.8 events per hour lower for the treatment group; AHI (continuous) of -25.0 events per hour lower for the treatment group; arousal events per hour of -15.2 lower for the treatment group; percent of sleep in REM of 2.4 percent higher for the treatment group; patients with marked or moderate improvement in patient global assessment was 55 percent higher in the treatment group; ODI = 4 percent was -22.7 events per hour lower for the treatment group; and the Epworth sleepiness scale was -3.7 lower for the treatment group. At 12 months, 138 (91 percent) of the patients were free from device, implant, and therapy related adverse events. --------------------------------------------------------------------------- \107\ Costanzo, M.R., Ponikowski, P., Javaheri, S., Augostini, R., Goldberg, L., Holcomb, R., Abraham, W.T.,''Transvenous Neurostimulation for Centra Sleep Apnoea: A randomised controlled trial,'' Lacet, 2016, vol. 388, pp. 974-982. \108\ Ibid. --------------------------------------------------------------------------- The final study data was from the pivotal study with limited information in the form of an abstract \109\ and an executive summary.\110\ The executive summary detailed an exploratory analysis of the 141 patients enrolled in the pivotal trial which were patients diagnosed with CSA. The abstract indicated that the 141 patients from the pivotal trial were randomized to either the treatment arm (68 patients) in which initiation of treatment began 1 month after implantation of the remed[emacr][supreg] System device with a 6-month follow-up period, or to the control group arm (73 patients) in which the initiation of treatment with the remed[emacr][supreg] System device was delayed for 6 months after implantation. Randomization efficacy was compared across baseline polysomnography and associated respiratory indices in which four of the five measures showed no statistical differences between those treated and controls; treated patients had an average MAI score of 3.1 as compared to control patients with an average MAI score of 2.2 (p=0.029). Patients included in the trial must have been medically stable, at least 18 years old, have had an electroencephalogram within 40 days of scheduled implantation, had an apnoea-hypopnoea index (AHI) of 20 events per hour or greater, a central apnoea index at least 50 percent of all apneas, and an obstructive apnea index less than or equal to 20 percent.\111\ Primary exclusion criteria were CSA caused by pain medication, heart failure of state D from the American Heart Association, a new implantable cardioverter defibrillator, pacemaker dependent subjects without any physiologic escape rhythm, evidence of phrenic nerve palsy, documented history of psychosis or severe bipolar disorder, a cerebrovascular accident within 12 months of baseline testing, limited pulmonary function, baseline oxygen saturation less than 92 percent while awake and on room air, active infection, need for renal dialysis, or poor liver function.\112\ Patients included in this trial were primarily male (89 percent), white (95 percent), with at least one comorbidity with cardiovascular conditions being most prevalent (heart failure at 64 percent), with a concomitant implantable cardiovascular stimulation device in 42 percent of patients at baseline. The applicant stated that, after randomization, there were no statistically significant differences between the treatment and control groups, with the exception of the treated group having a statistically higher rate of events per hour on the mixed apnea index (MAI) at baseline than the control group. --------------------------------------------------------------------------- \109\ Goldberg, L., Ponikowski, P., Javaheri, S., Augostini, R., McKane, S., Holcomb, R., Costanzo, M.R., ``In Heart Failure Patients with Central Sleep Apnea, Transvenous Stimulation of the Phrenic Nerve Improves Sleep and Quality of Life,'' Heart Failure Society of America, 21st annual meeting. 2017. \110\ Respicardia, Inc.

Remede System Pivotal Trial. https://clinicaltrials.gov/ct2/show/NCT01816776. \112\ Ibid. --------------------------------------------------------------------------- The applicant asserted that the results from the pivotal trial \113\ allow for the comparison of heart failure status in patients; we note that patients with American Heart Association objective assessment Class D (Objective evidence of severe cardiovascular disease. Severe limitations. Experiences symptoms even while at rest) were excluded from this pivotal trial. The primary endpoint in the pivotal trial was the proportion of patients with an AHI reduction greater than or equal to 50 percent at 6 months. When controlling for heart failure status, both treated groups experienced a statistically greater proportion of patients with AHI reductions than the controls at 6 months (58 percent more of treated patients with diagnoses of heart failure and 35 percent more of treated patients without diagnoses of heart failure as compared to their respective controls). The secondary endpoints assessed were the CAI average events per hour, AHI average events per hour, arousal index (ArI) average events per hour, percent of sleep in REM, and oxygen desaturation index 4 percent (ODI = 4 percent) average events per hour. Excluding the percent of sleep in REM, the treatment groups for both patients with diagnoses of heart failure and non-heart failure conditions experienced statistically greater improvements at 6 months on all secondary endpoints as compared to their respective controls. Lastly, quality of life secondary endpoints were assessed by the Epworth sleepiness scale (ESS) average scores and the patient global assessment (PGA). For both the ESS and PGA assessments, both treatment groups of patients with diagnoses of heart failure and non-heart failure conditions had statistically beneficial changes between baseline and 6 months as compared to their respective control groups. --------------------------------------------------------------------------- \113\ Respicardia, Inc. (n.d.). Remede System Pivotal Trial. https://clinicaltrials.gov/ct2/show/NCT01816776. --------------------------------------------------------------------------- The applicant provided analyses from the above report focusing on the primary and secondary polysomnography endpoints, specifically, across patients who had been diagnosed with CSA with heart failure and non-heart failure. Eighty patients included in the study from the executive summary report had comorbid heart failure, while 51 patients did not. Of those patients with heart failure, 35 were treated while 45 patients were controls. Of those patients without heart failure, 23 were treated and 28 patients were controls. The applicant did not provide baseline descriptive statistical comparisons between treated and control groups controlling for heart failure status. Across all primary and secondary endpoints, the patient group who were diagnosed with CSA and comorbid heart failure experienced statistically significant improvements. Excepting percent of sleep in REM, the patient group who were diagnosed with CSA without comorbid heart failure experienced statistically significant improvements in all primary and secondary endpoints. In the FY 2019 IPPS/LTCH PPS proposed rule, we invited public comments on whether this current study design is sufficient to support substantial clinical improvement of the remed[emacr][supreg] System with respect to all patient populations, [[Page 41318]] particularly the non-heart failure population. As previously noted, the applicant also contends that the technology offers a treatment option for a patient population unresponsive to, or ineligible for, currently available treatment options. Specifically, the applicant stated that the remed[emacr][supreg] System is the only treatment option for patients who have been diagnosed with moderate to severe CSA; published studies on positive pressure treatments like CPAP and ASV have not met primary endpoints; and there was an increase in cardiovascular mortality according to the ASV study. According to the applicant, approximately 40 percent of patients who have been diagnosed with CSA have heart failure. The applicant asserted that the use of the remed[emacr][supreg] System not only treats and improves the symptoms of CSA, but there is evidence of reverse remodeling in patients with reduced left ventricular ejection fraction (LVEF). In the proposed rule we stated we were concerned that the remed[emacr][supreg] System is not directly compared to the CPAP or ASV treatment options, which, to our understanding, are the current treatment options available for patients who have been diagnosed with CSA without heart failure. We noted that the FDA-approved indication for the implantation of the remed[emacr][supreg] System is for use in the treatment of adult patients who have been diagnosed with moderate to severe CSA. We also noted that the applicant's supporting studies were directed primarily at patients who had been treated with the remed[emacr][supreg] System who also had been diagnosed with heart failure. The applicant asserted that it would not be appropriate to use CPAP and ASV treatment options when comparing CPAP and ASV to the remed[emacr][supreg] System in the patient population of heart failure diagnoses because these treatment options have been found to increase mortality outcomes in this population. In light of the limited length of time in which the remed[emacr][supreg] System has been studied, we indicated we were concerned that any claims on mortality as they relate to treatment involving the use of the remed[emacr][supreg] System may be limited. Therefore, we were concerned as to whether there is sufficient data to determine that the technology represents a substantial clinical improvement with respect to patients who have been diagnosed with CSA without heart failure. We stated in the proposed rule that the applicant has shown that, among the subpopulation of patients who have been diagnosed with CSA and heart failure, the remed[emacr][supreg] System decreases morbidity outcomes as compared to the CPAP and ASV treatment options. In the proposed rule, we noted that we understood that not all patients evaluated in the applicant's supporting clinical trials had been diagnosed with CSA with a comorbidity of heart failure. However, in all of the supporting studies for this application, the vast majority of study patients did have this specific comorbidity of CSA and heart failure. Of the three studies which enrolled both patients diagnosed with CSA with and without heart failure,114 115 116 117 only two studies performed analyses controlling for heart failure status.118 119 The data from these two studies, the Costanzo, et al. (2016) and the Respicardia, Inc. executive report, are analyses based on the same pivotal trial data and, therefore, do not provide results from two separate samples. Descriptive comparisons are made in the executive summary of the pivotal trial \120\ between all treated and control patients. However, we were unable to determine the similarities and differences between patients with heart failure and non-heart failure treated versus controlled groups. Because randomization resulted in one difference between the overall treated and control groups (MAI events per hour), we stated that it is possible that further failures of randomization may have occurred when controlling for heart failure status in unmeasured variables. Finally, the sample size analyzed and the subsample sizes of the heart failure patients (80) and non-heart failure patients (51) are particularly small. We stated that it is possible that these results are not representative of the larger population of patients who have been diagnosed with CSA. --------------------------------------------------------------------------- \114\ Respicardia, Inc.

Specifically, the two patient populations, those who have been diagnosed with heart failure and CSA versus those who have been diagnosed with CSA alone, may experience different symptoms and outcomes associated with their disease processes. Patients who have been diagnosed with CSA alone present with excessive sleepiness, poor sleep quality, insomnia, poor concentration, and inattention.\121\ Conversely, patients who have been diagnosed with the comorbid conditions of CSA as a result of heart failure experience significant cardiovascular insults resulting from sympathetic nervous system activation, pulmonary hypertension, and arrhythmias, which ultimately contribute to the downward cycle of heart failure.\122\ --------------------------------------------------------------------------- \121\ Badr, M.S., 2017, Dec 11, ``Central sleep apnea: Risk factors, clinical presentation, and diagnosis,'' Available at: https://www.uptodate.com/contents/central-sleep-apnea-risk-factors-clinical-presentation-and-diagnosis?csi=d3a535e6-1cca-4cd5-ab5e-50e9847bda6c&source=contentShare. \122\ Abraham, W., Jagielski, D., Oldenburg, O., Augostini, R., Kreuger, S., Kolodziej, A., Ponikowski, P., ``Phrenic Nerve Stimulation for the Treatment of Central Sleep Apnea,'' JACC: Heart Failure, 2015, vol. 3(5), pp. 360-369. --------------------------------------------------------------------------- We also noted that the clinical study had a small patient population (n=151), with follow-up for 6 months. We stated that we were interested in longer follow-up data that would further validate the points made by the applicant regarding the beneficial outcomes seen in patients who have been diagnosed with CSA who have been treated using the remed[emacr][supreg] System. We also expressed interest in additional information regarding the possibility of electrical stimulation of unintended targets and devices combined with the possibility of interference from outside devices. Furthermore, we stated that we were unsure with regard to the longevity of the implanted device, batteries, and leads because it appears that the technology is meant to remain in use for the remainder of a patient's life. We invited public comments on whether the remed[emacr][supreg] System represents a substantial clinical improvement over existing technologies. Comment: The applicant provided responses to CMS' substantial clinical improvement concerns presented in the FY 2019 IPPS/LTCH PPS proposed rule [[Page 41319]] regarding the use of the remed[emacr][supreg] System. With regard to CMS' concern that the clinical studies of the remed[emacr][supreg] System did not include comparisons to PAP treatments, which are available treatment options for non-heart failure patients who have been diagnosed with CSA, the applicant stated that the following are several reasons for not using PAP treatments as comparators in their clinical trials: Other clinical trials, such as the CANPAP and SERVE-HF, which used PAP treatments in the course of treating patients who had been diagnosed with CSA were halted early due to the possibility of increased mortality; There exists little evidence showing that PAP treatments are effective for treatment of non-heart failure patients who have been diagnosed with CSA, according to the AASM; and Prior to the development of the remed[emacr][supreg] System's pivotal trial, there was a lack of prospective, randomized data showing a relationship between PAP treatments and morbidity outcomes. The applicant also believed that positive airway pressure devices were more likely to be considered for use in the treatment of patients who have been diagnosed with CSA, but without a diagnosis of heart failure. Another commenter stated that it agreed with the applicant's reasons and supported the rationale for not using PAP treatments as comparators in its clinical trials. With regard to CMS' concern that claims related to mortality following treatment with the remed[emacr][supreg] System are limited, the applicant agreed with CMS' assessment and stated that limited research on the system's impact on mortality for patients who have been diagnosed with CSA has been completed. The applicant further noted that mortality information was collected primarily for safety purposes during the pivotal trial. Another commenter also agreed with CMS' and the applicant's assessment and reiterated the applicant's statements. The applicant addressed CMS' concern that the FDA-approved indication for the remed[emacr][supreg] System is for all patients diagnosed with moderate to severe CSA and not specifically those diagnosed with a heart failure comorbidity. The applicant stated that the data from the pivotal trial provided evidence that the use of the remed[emacr][supreg] System as a treatment option is safe and effective for patients who have been diagnosed with CSA, regardless of a heart failure comorbidity. Another commenter agreed with the applicant and stated that the data from the pivotal trial supported the applicant's response regarding the concern of the FDA-approved indication. Regarding the concern that baseline statistical comparisons between treatment groups were not provided controlling for heart failure status, the applicant stated that there were no significant differences in baseline CSA disease burden between the treatment and control groups. The applicant further stated that, as expected, the heart failure and non-heart failure groups differed slightly by age and cardiac (for example, atrial fibrillation and hypertension) and other comorbidities (for example, hospitalizations within the last 12 months, diabetes, renal disease, depression). In regard to the results at 6 and 12 months, the applicant stated that in all categories, except for quality of life, both the heart failure and non-heart failure groups showed statistically significant improvements from the baseline. The applicant asserted that for quality of life, which did not have a baseline, both groups had greater than 50 percent of respondents, which demonstrates marked or moderate improvement to their quality of life with a higher proportion in the non-heart failure group as compared to the heart failure group. Another commenter added that given the overall consistent balance achieved between the treatment and control groups across the many baseline variables examined, there is no evidence suggesting noteworthy imbalances to be expected in these subgroups. The applicant addressed CMS' concerns related to the differences between heart failure and non-heart failure patients who received treatment with the remed[emacr][supreg] System. The applicant asserted that it is well established that a significant proportion of patients who have been diagnosed with CSA have a heart failure comorbidity; 64 percent of patients enrolled in the pivotal trial had a diagnosis of heart failure. The applicant stated that it expected a higher proportion of heart failure patients enrolled in the study of CSA due to the correlated incidence of these diseases and the pivotal trial inclusion criteria being based on conventional sleep apnea metrics and not comorbidities. The applicant further stated that, regardless of the patients' comorbidity status, patients experienced consistent and durable improvements with the use of the remed[emacr][supreg] System as a treatment option. The applicant responded to CMS' concern regarding the small sample size used for the pivotal trial. The applicant stated that the sample size was chosen with an alpha error of 0.025, a power of 80 percent, an expected 50 percent response rate in the treatment group, and a 25 percent response rate in the control group. The applicant further stated that the study accounted for a 15 percent implantation failure and a 10 percent drop-out rate. The applicant indicated that, ultimately, the trial randomized 151 patients, with 147 successful implantations. Another commenter stated that the results showing highly statistical significance were derived from a sample size of patients across 31 different places around the world and, therefore, are generalizable. The applicant responded to CMS' interest in longer term follow-up data. The applicant stated that 12-month follow-up data was recently published providing 12 months of treatment data for patients enrolled in the treated group and 6 months of treatment data for patients enrolled in the control group. Other commenters stated that 12-month follow-up data results are available and show continued durability of 6-month results. The applicant addressed CMS' concern about the potential for electrical stimulation of unintended targets and interference from outside devices. The applicant stated that 42 percent of the patients involved in the pivotal trial had a concomitant cardiac device. The applicant stated that interactions between devices are not unique to the remed[emacr][supreg] System and that only three serious device interactions were reported, all of which were resolved with reprogramming. The applicant further indicated that, all except 1 of the 21 extra-respiratory stimulation cases that occurred were resolved with routine reprogramming of the remed[emacr][supreg] System, the other required repositioning of the lead. Ultimately, 96 percent of the patients enrolled in the pivotal trial would elect to have the medical procedure again. Lastly, the applicant addressed CMS' concern about longevity of the implanted device, batteries, and leads. The applicant stated that the expected typical battery life is 41 months, which is consistent with other implanted neurostimulation devices. The applicant further stated that the leads were FDA pre-market approved and designed based on predicate, permanent cardiac pacing leads for which the standards are more rigorous than those for neurostimulation. The applicant indicated that, the leads, therefore, compare favorably to leads used for neurostimulation in categories such as lead breakage, connector failure, lead dislodgement, and infection. [[Page 41320]] Another commenter responded to CMS' concern about the possible failure in randomization when controlling for heart failure status. The commenter stated that it does not consider the reported baseline difference as a failure of randomization. The commenter further noted that, of the approximately 50 baseline factors examined and reported in the clinical study report from the pivotal trial, only MAI had a p- value equal to less than 0.05 associated with a study group difference. Many commenters stated that the remed[emacr][supreg] System represented a substantial clinical improvement and referenced clinical data, in general, and others specifically mentioned the pivotal trial results as demonstration of the improved benefit over existing treatment options. These commenters also noted that the use of the remed[emacr][supreg] System and the mechanism of action of phrenic nerve stimulation showed sustained benefits for patients who have been diagnosed with CSA and received treatment using the system. Response: We appreciate the thoroughness of the additional information and analyses provided by the applicant and commenters in response to our concerns regarding whether the technology meets the substantial clinical improvement criterion. We agree with the applicant and commenters that the use of the remed[emacr][supreg] System represents a substantial clinical improvement over existing technologies because, based on the information provided by the applicant, it substantially improves relevant metrics related to the CSA condition, regardless of whether there is the presence of heart failure comorbidities. Specifically, the applicant provided data which demonstrated the effectiveness of the remed[emacr][supreg] System for the treatment of moderate and severe CSA in all treated patients, regardless of a heart failure comorbidity. Patients without a diagnosis of heart failure benefited from treatment involving the remed[emacr][supreg] System, as well as those with a diagnosis of heart failure. Furthermore, the applicant and commenters provided evidence to allay our concerns as they related to a lack of use of CPAP as a comparator for the remed[emacr][supreg] System in clinical trials, baseline data regarding differences between heart failure and non-heart failure groups, a small sample size in the pivotal trial, longer term follow-up data, the potential for interplay between concomitant devices, and the longevity of the device, batteries, and leads. After consideration of the public comments we received, we have determined that the remed[emacr][supreg] System meets all of the criteria for approval for new technology add-on payments. Therefore, we are approving new technology add-on payments for the remed[emacr][supreg] System for FY 2019. Cases involving the use of the remed[emacr][supreg] System that are eligible for new technology add-on payments will be identified by ICD-10-PCS procedures codes 0JH60DZ and 05H33MZ in combination with procedure code 05H03MZ (Insertion of neurostimulator lead into right innominate vein, percutaneous approach) or 05H043MZ (Insertion of neurostimulator lead into left innominate vein, percutaneous approach). In its application, the applicant estimated that the average Medicare beneficiary would require the surgical implantation of one remed[emacr][supreg] System per patient. According to the application, the cost of the remed[emacr][supreg] System is $34,500 per patient. Under Sec. 412.88(a)(2), we limit new technology add-on payments to the lesser of 50 percent of the average cost of the technology, or 50 percent of the costs in excess of the MS-DRG payment for the case. As a result, the maximum new technology add-on payment for a case involving the use of the remed[emacr][supreg] System is $17,250 for FY 2019. In accordance with the current indication for the use of the remed[emacr][supreg] System, CMS expects that the remed[emacr][supreg] System will be used for the treatment of adult patients who have been diagnosed with moderate to severe CSA. e. Titan Spine nanoLOCK[supreg] (Titan Spine nanoLOCK[supreg] Interbody Device) Titan Spine submitted an application for new technology add-on payments for the Titan Spine nanoLOCK[supreg] Interbody Device (the Titan Spine nanoLOCK[supreg]) for FY 2019. (We note that the applicant previously submitted an application for new technology add-on payments for this device for FY 2017.) The Titan Spine nanoLOCK[supreg] is a nanotechnology-based interbody medical device with a dual acid-etched titanium interbody system used to treat patients diagnosed with degenerative disc disease (DDD). One of the key distinguishing features of the device is the surface manufacturing technique and materials, which produce macro, micro, and nano-surface textures. According to the applicant, the combination of surface topographies enables initial implant fixation, mimics an osteoclastic pit for bone growth, and produces the nano-scale features that interface with the integrins on the outside of the cellular membrane. Further, the applicant noted that these features generate better osteogenic and angiogenic responses that enhance bone growth, fusion, and stability. The applicant asserted that the Titan Spine nanoLOCK[supreg]'s clinical features also reduce pain, improve recovery time, and produce lower rates of device complications such as debris and inflammation. On October 27, 2014, the Titan Spine nanoLOCK[supreg] received FDA clearance for the use of five lumbar interbody devices and one cervical interbody device: The nanoLOCK[supreg] TA--Sterile Packaged Lumbar ALIF Interbody Fusion Device with nanoLOCK[supreg] surface, available in multiple sizes to accommodate anatomy; the nanoLOCK[supreg] TAS-- Sterile Packaged Lumbar ALIF Stand Alone Interbody Fusion Device with nanoLOCK[supreg] surface, available in multiple sizes to accommodate anatomy; the nanoLOCK[supreg] TL--Sterile Packaged Lumbar Lateral Approach Interbody Fusion Device with nanoLOCK[supreg] surface, available in multiple sizes to accommodate anatomy; the nanoLOCK[supreg] TO--Sterile Packaged Lumbar Oblique/PLIF Approach Interbody Fusion Device with nanoLOCK[supreg] surface, available in multiple sizes to accommodate anatomy; the nanoLOCK[supreg] TT--Sterile Packaged Lumbar TLIF Interbody Fusion Device with nanoLOCK[supreg] surface, available in multiple sizes to accommodate anatomy; and the nanoLOCK[supreg] TC--Sterile Packaged Cervical Interbody Fusion Device with nanoLOCK[supreg] surface, available in multiple sizes to accommodate anatomy. The applicant received FDA clearance on December 14, 2015, for the nanoLOCK[supreg] TCS--Sterile Package Cervical Stand Alone Interbody Fusion Device with nanoLOCK[supreg] surface, available in multiple sizes to accommodate anatomy. According to the applicant, July 8, 2016, was the first date that the nanotechnology production facility completed validations and clearances needed to manufacture the nanoLOCK[supreg] interbody fusion devices. Once validations and clearances were completed, the technology was available on the U.S. market on October 1, 2016. Therefore, the applicant believes that the newness period for nanoLOCK[supreg] would begin on October 1, 2016. Procedures involving the Titan Spine nanoLOCK[supreg] technology can be identified by the following ICD-10-PCS Section ``X'' New Technology codes: XRG0092 (Fusion of occipital-cervical joint using nanotextured surface interbody fusion device, open approach); [[Page 41321]] XRG1092 (Fusion of cervical vertebral joint using nanotextured surface interbody fusion device, open approach); XRG2092 (Fusion of 2 or more cervical vertebral joints using nanotextured surface interbody fusion device, open approach); XRG4092 (Fusion of cervicothoracic vertebral joint using nanotextured surface interbody fusion device, open approach); XRG6092 (Fusion of thoracic vertebral joint using nanotextured surface interbody fusion device, open approach); XRG7092 (Fusion of 2 to 7 thoracic vertebral joints using nanotextured surface interbody fusion device, open approach); XRG8092 (Fusion of 8 or more thoracic vertebral joints using nanotextured surface interbody fusion device, open approach); XRGA092 (Fusion of thoracolumbar vertebral joint using nanotextured surface interbody fusion device, open approach); XRGB092 (Fusion of lumbar vertebral joint using nanotextured surface interbody fusion device, open approach); XRGC092 (Fusion of 2 or more lumbar vertebral joints using nanotextured surface interbody fusion device, open approach); and XRGD092 (Fusion of lumbosacral joint using nanotextured surface interbody fusion device, open approach). We note that the applicant expressed concern that interbody fusion devices that have failed to gain or apply for FDA clearance with nanoscale features could confuse health care providers with marketing and advertising using terms related to nanotechnology and ultimately adversely affect patient outcomes. As discussed previously, if a technology meets all three of the substantial similarity criteria, it would be considered substantially similar to an existing technology and would not be considered ``new'' for the purposes of new technology add-on payments. In the proposed rule we noted that the substantial similarity discussion is applicable to both the lumbar and the cervical interbody devices because all of the devices use the Titan Spine nanoLOCK[supreg] technology. With regard to the first criterion, whether a product uses the same or a similar mechanism of action to achieve a therapeutic outcome, the applicant stated that, for both interbody devices (the lumbar and the cervical interbody device), the Titan Spine nanoLOCK[supreg]'s surface stimulates osteogenic cellular response to assist in bone formation during fusion. According to the applicant, the mechanism of action exhibited by the Titan Spine's nanoLOCK[supreg] surface technology involves the ability to create surface features that are meaningful to cellular regeneration at the nano-scale level. During the manufacturing process, the surface produces macro, micro, and nano-surface textures. The applicant believed that this unique combination and use of these surface topographies represents a new approach to stimulating osteogenic cellular response. The applicant further asserted that the macro-scale textured features are important for initial implant fixation; the micro-scale textured features mimic an osteoclastic pit for supporting bone growth; and the nano-scale textured features interface with the integrins on the outside of the cellular membrane, which generates the osteogenic and angiogenic (mRNA) responses necessary to promote healthy bone growth and fusion. The applicant stated that when correctly manufactured, an interbody fusion device includes a hierarchy of complex surface features, visible at different levels of magnification, that work collectively to impact cellular response through mechanical, cellular, and biochemical properties. The applicant stated that Titan Spine's proprietary and unique surface technology, the Titan Spine nanoLOCK[supreg] interbody devices, contain optimized nano surface characteristics, which generate the distinct cellular responses necessary for improved bone growth, fusion, and stability. The applicant further stated that the Titan Spine nanoLOCK[supreg]'s surface engages with the strongest portion of the vertebral endplate, which enables better resistance to subsidence because a unique dual acid-etched titanium surface promotes earlier bone in-growth. According to the applicant, the Titan Spine nanoLOCK[supreg]'s surface is created by using a reductive process of the titanium itself. The applicant asserted that use of the Titan Spine nanoLOCK[supreg] significantly reduces the potential for debris generated during impaction when compared to treatments using Polyetheretherketone (PEEK)-based implants coated with titanium. According to the results of an in vitro study (provided by the applicant), which examined factors produced by human mesenchymal stem cells on spine implant materials that compared angiogenic factor production using PEEK-based versus titanium alloy surfaces, osteogenic production levels were greater with the use of rough titanium alloy surfaces than the levels produced using smooth titanium alloy surfaces. Human mesenchymal stem cells were cultured on tissue culture polystyrene, PEEK, smooth TiAlV, or macro-/micro-/nanotextured rough TiAlV (mmnTiAlV) disks. Osteoblastic differentiation and secreted inflammatory interleukins were assessed after 7 days. The results of an additional study provided by the applicant examined whether inflammatory microenvironment generated by cells as a result of use of titanium aluminum-vanadium (Ti-alloy, TiAlV) surfaces is effected by surface micro texture, and whether it differs from the effects generated by PEEK-based substrates. This in vitro study compared angiogenic factor production and integrin gene expression of human osteoblast-like MG63 cells cultured on PEEK or titanium-aluminum vanadium (titanium alloy). Based on these study results, the applicant asserted that the use of micro textured surfaces has demonstrated greater promotion of osteoblast differentiation when compared to use of PEEK-based surfaces. The applicant maintains that the nanoLOCK[supreg] was the first, and remains the only, device in spinal fusion, to apply for and successfully obtain a clearance for nanotechnology from the FDA. According to the applicant, in order for a medical device to receive a nanotechnology FDA clearance, the burden of proof includes each of the following to be present on the medical device in question: (1) Proof of specific nano scale features, (2) proof of capability to manufacture nano-scale features with repeatability and documented frequency across an entire device, and (3) proof that those nano-scale features provide a scientific benefit, not found on devices where the surface features are not present. The applicant further stated that many of the commercially available interbody fusion devices are created using additive manufacturing processes to mold or build surface from the ground up. Conversely, Titan Spine applied a subtractive surface manufacturing to remove pieces of a surface. The surface features that remain after this subtractive process generate features visible at magnifications that additive manufacturing has not been able to produce. According to the applicant, this subtractive process has been validated by the White House Office of Science and Technology, the National Nanotechnology Initiative, and the FDA that provide clearances to products that [[Page 41322]] exhibit unique and repeatable features at predictive frequency due to a manufacturing technique. With regard to the second criterion, whether a product is assigned to the same or a different MS-DRG, cases representing patients that may be eligible for treatment involving the Titan Spine nanoLOCK[supreg] technology would map to the same MS-DRGs as other (lumbar and cervical) interbody devices currently available to Medicare beneficiaries and also are used for the treatment of patients who have been diagnosed with DDD (lumbar or cervical). With regard to the third criterion, whether the new use of the technology involves the treatment of the same or similar type of disease and the same or similar patient population, the applicant stated that the Titan Spine nanoLOCK[supreg] can be used in the treatment of patients who have been diagnosed with similar types of diseases, such as DDD, and for a similar patient population receiving treatment involving both lumbar and cervical interbody devices. In summary, the applicant maintained that the Titan Spine nanoLOCK[supreg] technology has a different mechanism of action when compared to other spinal fusion devices. Therefore, the applicant did not believe that the Titan Spine nanoLOCK[supreg] technology is substantially similar to existing technologies. In the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20316), we stated we were concerned that the Titan Spine nanoLOCK[supreg] interbody devices may be substantially similar to currently available titanium interbody devices because other roughened surface interbody devices also stimulate bone growth. While there is a uniqueness to the nanotechnology used by the applicant, other devices also stimulate bone growth such as PEEK-based surfaces and, therefore, we were concerned that the Titan Spine nanoLOCK[supreg] interbody devices use the same or similar mechanism of action as other devices. We invited public comments on whether the Titan Spine nanoLOCK[supreg] interbody devices are substantially similar to existing technologies and whether these devices meet the newness criterion. Comment: One commenter stated that similar products to the nanoLOCK[supreg] interbody devices exist, and there is no unbiased research to support the applicant's claims of the technology's results. Several commenters referenced studies that show that nano-scale enhanced Ti6A14V interbody fusion device surfaces promote a cellular response to bone growth. The commenters stated that these studies show that cells in the osteoblast lineage (MSCs, osteoprogenitor cells, and osteoblasts) exhibited a more mature osteoblast phenotype when grown on microtextured Ti and Ti6Al4V surfaces than on tissue culture polystyrene (TCPS) or on other polymers like PEEK. The commenters further stated that, moreover, cells on the Ti6Al4V surfaces produced less inflammatory mediators, less apoptotic factors and less necrosis factors than cells on PEEK surfaces (rough < smooth Ti6Al4V <<< smooth PEEK) and that PEEK surfaces have long been associated with increased fibrous encapsulation in vivo, which was recently identified to be due to a direct upregulation of inflammatory factors from mesenchymal stem cells growing on PEEK. Response: We agree with the commenter that similar products to the nanoLOCK[supreg] interbody devices exist. We also believe that the current research supports the applicant's assertion that the technology's nanoscale features, which exhibit a biological effect (osteoblastic activity), have not been seen in other interbody fusion devices. After consideration of the public comments we received, we believe that the Titan Spine nanoLock[supreg] uses a unique mechanism of action, a nano-scale level surface technology, to enhance bone growth. Therefore, we believe the Titan Spine nanoLock[supreg] is not substantially similar to other existing technologies and meets the newness criterion. The applicant provided three analyses of claims data from the FY 2016 MedPAR file to demonstrate that the Titan Spine nanoLOCK[supreg] interbody devices meet the cost criterion. In the proposed rule, we noted that cases reporting procedures involving lumbar and cervical interbody devices would map to different MS-DRGs. As discussed in the Inpatient New Technology Add On Payment Final Rule (66 FR 46915), two separate reviews and evaluations of the technologies are necessary in this instance because cases representing patients receiving treatment for diagnoses associated with lumbar procedures that may be eligible for use of the technology under the first indication would not be expected to be assigned to the same MS DRGs as cases representing patients receiving treatment for diagnoses associated with cervical procedures that may be eligible for use of the technology under the second indication. Specifically, cases representing patients who have been diagnosed with lumbar DDD and who have received treatment that involved implanting a lumbar interbody device would map to MS DRG 028 (Spinal Procedures with MCC), MS-DRG 029 (Spinal Procedures with CC or Spinal Neurostimulators), MS DRG 030 (Spinal Procedures without CC/ MCC), MS-DRG 453 (Combined Anterior/Posterior Spinal Fusion with MCC), MS-DRG 454 (Combined Anterior/Posterior Spinal Fusion with CC), MS-DRG 455 (Combined Anterior/Posterior Spinal Fusion without CC/MCC), MS-DRG 456 (Spinal Fusion Except Cervical with Spinal Curvature or Malignancy or Infection or Extensive Fusions with MCC), MS DRG 457 (Spinal Fusion Except Cervical with Spinal Curvature or Malignancy or Infection or Extensive Fusion without MCC), MS-DRG 458 (Spinal Fusion Except Cervical with Spinal Curvature or Malignancy or Infection or Extensive Fusions without CC/MCC), MS-DRG 459 (Spinal Fusion Except Cervical with MCC), and MS-DRG 460 (Spinal Fusion Except Cervical without MCC). Cases representing patients who have been diagnosed with cervical DDD and who have received treatment that involved implanting a cervical interbody device would map to MS DRG 471 (Cervical Spinal Fusion with MCC), MS- DRG 472 (Cervical Spinal Fusion with CC), and MS-DRG 473 (Cervical Spinal Fusion without CC/MCC). Procedures involving the implantation of lumbar and cervical interbody devices are assigned to separate MS DRGs. Therefore, the devices categorized as lumbar interbody devices and the devices categorized as cervical interbody devices must distinctively (each category) meet the cost criterion and the substantial clinical improvement criterion in order to be eligible for new technology add on payments beginning in FY 2019. The first analysis searched for any of the ICD-10-PCS procedure codes within the code series Lumbar-0SG [body parts 0 1 3] [open approach only 0] [device A only] [anterior column only 0, J], which typically are assigned to MS DRGs 028, 029, 030, and 453 through 460. The average case-weighted unstandardized charge per case was $153,005. The applicant then removed charges related to the predicate technology and then standardized the charges. The applicant then applied an inflation factor of 1.09357, the value used in the FY 2018 IPPS/LTCH PPS final rule (82 FR 38527) to update the charges from FY 2016 to FY 2018. The applicant added charges related to the Titan Spine nanoLOCK[supreg] lumbar interbody devices. This resulted in a final inflated average case-weighted standardized charge per case of $174,688, which exceeded the average [[Page 41323]] case-weighted Table 10 MS-DRG threshold amount of $83,543. The second analysis searched for any of the ICD-10-PCS procedure codes within the code series Cervical-0RG [body parts 0-A] [open approach only 0] [device A only] [anterior column only 0, J], which typically are assigned to MS-DRGs 028, 029, 030, 453 through 455, and 471 through 473. The average case-weighted unstandardized charge per case was $88,034. The methodology used in the first analysis was used for the second analysis, which resulted in a final inflated average case-weighted standardized charge per case of $101,953, which exceeded the average case-weighted Table 10 MS-DRG threshold amount of $83,543. The third analysis was a combination of the first and second analyses described earlier that searched for any of the ICD-10-PCS procedure codes within the Lumbar and Cervical code series listed above that are assigned to the MS-DRGs in the analyses above. The average case-weighted unstandardized charge per case was $127,736. The methodology used for the first and second analysis was used for the third analysis, which resulted in a final inflated average case- weighted standardized charge per case of $149,915, which exceeded the average case-weighted Table 10 MS-DRG threshold amount of $104,094. Because the final inflated average case-weighted standardized charge per case exceeded the average case-weighted threshold amount in all of the applicant's analyses, the applicant maintained that the technology met the cost criterion. We invited public comments on whether the Titan Spine nanoLOCK[supreg] meets the cost criterion. We did not receive any public comments concerning whether the Titan Spine nanoLOCK[supreg] meets the cost criterion or the cost analysis presented in the proposed rule. We believe that the Titan Spine nanoLOCK[supreg] meets the cost criterion. With regard to the substantial clinical improvement criterion for the Titan Spine nanoLOCK[supreg] Interbody Lumbar and Cervical Devices, the applicant submitted the results of two clinical evaluations. The first clinical evaluation was a case series and the second was a case control study. Regarding the case series, 4 physicians submitted clinical information on 146 patients. The 146 patients resulted from 2 surgery groups: A cervical group of 73 patients and a lumbar group of 73 patients. The division into cervical and lumbar groups was due to differences in surgical procedure and expected recovery time. Subsequently, the collection and analyses of data were presented for lumbar and cervical nanoLOCK[supreg] device implants. Data was collected using medical record review. Patient baseline characteristics, the reason for cervical and lumbar surgical intervention, inclusion and exclusion criteria, details on the types of pain medications and the pattern of usage preoperatively and postoperatively were not provided. In the proposed rule, we noted that the applicant did not provide an explanation of why the outcomes studied in the case series were chosen for review. However, the applicant noted that the case series data were restricted to patients treated with the Titan Spine nanoLOCK[supreg] device, with both retrospective and prospective data collection. These data appeared to be clinically related and included: (1) Pain medication usage; (2) extremity and back pain (assessed using the Numeric Pain Rating Scale (NPRS)); and (3) function (assessed using the Oswestry Disability Index (ODI)). Clinical data collection began with time points defined as ``Baseline (pre-operation), Month 1 (0-4 weeks), Month 2 (5-8 weeks), Month 3 (9-12 weeks), Month 4 (13-16 weeks), Month 5 (17-20 weeks) and Month 6+ (>20 weeks)''. The n, mean, and standard deviation were presented for continuous variables (NPRS extremity pain, back pain, and ODI scores), and the n and percentage were presented for categorical variables (subjects taking pain medications). All analyses compared the time point (for example, Month 1) to the baseline. Pain scores for extremities (leg and arm) were assessed using the NPRS, an 11 category ordinal scale where 0 is the lowest value and 10 is the highest value and, therefore, higher scores indicate more severe pain. Of the 73 patients in the lumbar group, the applicant presented data on 18 cases for leg or arm pain at baseline that had a mean score of 6.4, standard deviation (SD) 2.3. Between Month 1 and Month 6+ the number of lumbar patients for which data was submitted for leg or arm pain ranged from 3 patients (Month 5, mean score 3.7, SD 3.5) to 15 patients (Month 6+, mean score 2.5, SD 2.4), with varying numbers of patients for each of the other defined time points of Month 1 through Month 4. None of the defined time points of Month 1 through Month 4 had more than 14 patients or less than 3 patients that were assessed. Of the 73 patients in the cervical group, 7 were assessed for leg or arm pain at baseline and had a mean score of 5.1, SD 3.5. Between Month 1 and Month 6+ the number of cervical patients assessed for leg or arm pain ranged from 0 patients (Month 5, no scores) to 5 patients (Month 1, mean score 4.2, SD 2.6), with varying numbers of patients for each of the other defined time points of Month 1 through Month 4. None of the defined time points of Month 1 through Month 4 had more than 5 patients or less than 2 patients that were assessed. Back pain scores were also assessed using the NPRS, where 0 is the lowest value and 10 is the highest value and, therefore, higher scores indicate more severe pain. Of the 73 patients in the lumbar group, 66 were assessed for back pain at baseline and had a mean score of 7.9, SD 1.8. Between Month 1 and Month 6+ the number of lumbar patients assessed for back pain ranged from 4 patients (Month 5, mean score 4.0, SD 2.7) to 43 patients (Month 1, mean score 4.5, SD 2.7), with varying numbers of patients for each defined time point. Of the 73 patients in the cervical group, 71 were assessed for back pain at baseline and had a mean score of 7.5, SD 2.3. Between Month 1 and Month 6+ the number of cervical patients assessed for back pain ranged from 2 patients (Month 5, mean score 7.0, SD 2.8) to 47 patients (Month 1, mean score 4.4, SD 2.9), with varying numbers of patients for each defined time point. Function was assessed using the ODI, which ranges from 0 to 100, with higher scores indicating increased disability/impairment. Of the 73 patients in the lumbar group, 59 were assessed for ODI scores at baseline and had a mean score of 52.5, SD 18.7. Between Month 1 and Month 6+ the number of lumbar patients assessed for ODI scores ranged from 3 patients (Month 5, mean score 33.3, SD 19.8) to 38 patients (Month 1, mean score 48.1, SD 19.7), with varying numbers of patients for each defined time point. Of the 73 patients in the cervical group, 56 were assessed for ODI scores at baseline and had a mean score of 53.6, SD 18.2. Between Month 1 and Month 6+ the number of cervical patients assessed for ODI score ranged from 1 patient (Month 5, mean score 80, no SD noted) to 41 patients (Month 1, mean score 48.6, SD 20.5), with varying numbers of patients for each defined time point. The percentages of patients not taking pain medicines per day for the lumbar and cervical groups over time were assessed. Of the 73 patients in the lumbar group, 69 were assessed at baseline and 27.5 percent of the 69 patients were not taking pain medication. Between Month 1 and Month 6+ the number of lumbar patients assessed for not taking pain medicines ranged from 5 patients [[Page 41324]] (Month 5, 80 percent were not taking pain medicines) to 46 patients (Month 1, 54.3 percent were not taking pain medicines), with varying numbers of patients for each defined time point. Of the 73 patients in the cervical group, 72 were assessed and 22.2 percent of the 72 patients were not taking pain medicines at baseline. Between Month 1 and Month 6+ the number of cervical patients assessed for not taking pain medicines ranged from 2 patients (Month 5, 100 percent were not taking pain medicines) to 50 patients (Month 1, 70 percent were not taking pain medicines), with varying numbers of patients for each defined time point. According to the applicant, both the lumbar and cervical groups showed a trend of improvement in all four clinical outcomes over time for which they collected data in their case series. However, the applicant also indicated that the trend was difficult to assess due to the relatively limited number of subjects with available assessments more than 4 months post-implant. The applicant shared that it had missing values for over 80 percent of the subjects in the study after the 4th post-operative month. According to the applicant and its results of the clinical evaluation, which was based on data from less than 20 percent of subjects, there was a statistically significant reduction in back pain for nanoLOCK[supreg] patients from ``Baseline,'' based on improvement at earlier than standard time points. In the proposed rule, we stated we were concerned that the small sample size of patients assessed at each timed follow-up point for each of the clinical outcomes evaluated in the case series limited our ability to draw meaningful conclusions from these results. The applicant provided t-test results for the lumbar and cervical groups assessed for pain (back, leg, and arm). We indicated we were concerned that the t-test resulting from small sample sizes (for example, 2 of 73 patients in Month 5, and 5 of 73 patients in Month 6+) does not indicate a statistically meaningful improvement in pain scores. Based on the results of the case series provided by the applicant, we stated that we were unable to determine whether the findings regarding extremity and back pain, ODI scores, and percentage of subjects not taking pain medication for patients who received treatment involving the Titan Spine nanoLOCK[supreg] devices represent a substantial clinical improvement due to the inconsistent sample size over time across both treatment arms in all evaluated outcome measures. The quantity of missing data in this case series, along with the lack of explanation for the missing data, raised concerns for the interpretation of these results. We also stated that we were unable to determine based on this case series whether there were improvements in extremity pain and back pain, ODI scores, and percentage of subjects not taking pain medicines for patients who received treatment involving the Titan Spine nanoLOCK[supreg] devices versus conventional and other intervertebral body fusion devices, as there were no comparisons to current therapies. As noted in the proposed rule and above, the applicant did not provide an explanation of why the outcomes studied in the case series were chosen for review. Therefore, we believed that we may have had insufficient information to determine if the outcomes studied in the case series are validated proxies for evidence that the nanoLOCK[supreg]'s surface promotes greater osteoblast differentiation when compared to use of PEEK-based surfaces. We invited public comments regarding our concerns, including with respect to why the outcomes studied in the case series were chosen for review. We note that, we did not receive any public comments with respect to why the outcomes in the case series were selected for review. The applicant's second clinical evaluation was a case-control study with a 1:5 case to control ratio. The applicant used deterministically linked, de-identified, individual level health care claims, electronic medical records (EMR), and other data sources to identify 70 cases and 350 controls for a total sample size of 420 patients. The applicant also identified OM1TM data source and noted that the OM1TM data source reflects data from all U.S. States and territories and is representative of the U.S. national population. The applicant used OM1TM data between January 2016 and June 2017, and specifically indicated that these data contain medical and pharmacy claims information, laboratory data, vital signs, problem lists, and other clinical details. The applicant indicated that cases were selected using the ICD-10-PCS Section ``X'' New Technology codes listed above and controls were chosen from fusion spine procedures (Fusion Spine Anterior Cervical, Fusion Spine Anterior Cervical and Discectomy, Fusion Spine Anterior Posterior Cervical, Fusion Spine Transforaminal Interbody Lumbar, Fusion Spine Cervical Thoracic, Fusion Spine Transforaminal Interbody Lumbar with Navigation, and Fusion Spine Transforaminal Interbody Lumber Robot-Assisted). Further, the applicant stated that cases and controls were matched by age (within 5 years), year of surgery, Charlson Comorbidity Index, and gender. According to the applicant, regarding clinical outcomes studied, unlike the case series, the case-control study captured Charlson Comorbidity Index, the average length of stay (ALOS), and 30-day unplanned readmissions; like the case series, this case-control study captured the use of pain medications by assessing the cumulative post-surgical opioid use. The mean age for all patients in the study was 55 years old, and 47 percent were male. For the clinical length of stay outcome, the applicant noted that the mean length of stay was slightly longer among control patients, 3.9 days (SD=5.4) versus 3.2 days (SD=2.9) for cases, and a larger proportion of patients in the control group had lengths of stay equal to or longer than 5 days (21 percent versus 17 percent). Three control patients (0.8 percent) were readmitted within 30 days compared to zero readmissions among case patients. A slightly lower proportion of case patients were on opioids 3 months post-surgery compared to control patients (15 percent versus 16 percent). In the proposed rule (83 FR 20318), we stated we were concerned that there may be significant outliers not identified in the case and control arms because for the mean length of stay outcome, the standard deviation for control patients (5.4 days) is larger than the point estimate (3.9 days). Based on the results of this clinical evaluation provided by the applicant, we stated that we were unable to determine whether the findings regarding lengths of stay and cumulative post- surgical opioid use for patients who received treatment involving the nanoLOCK[supreg] devices versus conventional intervertebral body fusion devices represent a substantial clinical improvement. We stated that without further information on selection of controls and whether there were adjustments in the statistical analyses controlling for confounding factors (for example, cause of back pain, level of experience of the surgeon, BMI and length of pain), we were concerned that the interpretation of the results may be limited. Finally, we stated we were concerned that the current data does not adequately support a strong association between the outcome measures of length of stay, readmission rates, and use of opioids and the use of nano-surface textures in the manufacturing of the Titan Spine nanoLOCK[supreg] device. For these reasons, we stated that we were concerned that the current data do not support a substantial clinical [[Page 41325]] improvement over the currently available devices used for lumbar and cervical DDD treatment. In the proposed rule, we noted that the applicant indicated its intent to submit the results of additional ongoing studies to support the evidence of substantial clinical improvement over existing technologies for patients who received treatment involving the nanoLOCK[supreg] devices versus patients receiving treatment involving other interbody fusion devices. We invited public comments on whether the Titan Spine nanoLOCK[supreg] meets the substantial clinical improvement criterion. Comment: The applicant submitted a Milligram Morphine Equivalent (MME) analysis. According to the applicant, the purpose of the analysis is to demonstrate support for the ``substantial clinical value'' in the reduction of MME with the implant of a Titan Spine nanoLOCK[supreg] device. The applicant indicated that the MME analysis was conducted to assess the impact of nanoLOCK[supreg] versus control devices on total MME and narcotic usage. The applicant submitted the results of the MME analysis as additional demonstration to support the representation of a substantial clinical improvement over existing technologies as stated in their application, and indicated that the data will be published soon as a peer-reviewed journal article. The applicant explained that control devices represented a mix of interbody fusion devices, including PEEK and alternative roughened titanium devices without nano- surface technology. The applicant stated that all nanoLOCK[supreg] patients were classified as having an interbody fusion device with a nano technology coated surface. The applicant further indicated that all patients received either an allograft or autograft biologic in addition to the implant device. The applicant stated that follow-up time was recorded at 3 points: Follow-up #1--28.71 days (S.D. 20.64); Follow-up #2--65.07 days (S.D. 33.91); and Follow-up #3--104.21 days (S.D. 40.91). According to the applicant, a patient's baseline MME was also a significant predictor of MME at first follow-up when adjusted for all other variables in the model. The applicant stated that, at Follow-up #1, there was a total of 926 patients with data regarding the days from surgery to the first follow-up. The applicant indicated that, according to the MME analysis, of the 926 patients at the time of Follow-up #1, 47 patients had missing data. The applicant further stated that results show there were 873 patients with data on narcotic usage at the time of the first follow-up, with 100 patients with missing data, and 391 patients with data on the total MME, with 582 missing data at the time of final analysis of follow-up #1. The applicant stated that the results from the remaining 391 patients represent only 42 percent of the original study participants. The applicant explained that results indicated the mean total MME of patients was 21.83 units (SD: 42.63). The applicant further stated that there were 349 patients who were using narcotics for pain at the time of their first follow-up. The applicant explained that all missing data was addressed through pairwise deletion. The applicant believed that this analysis further demonstrated that patients who received nanoLOCK[supreg] had a significantly lower total MME at first follow-up when compared to control devices patients when adjusted for the following variables: Age, male versus female, history of prior spine surgery, current smoker versus non-smoker, baseline MME, concomitant medical condition, cervical versus lumbar, nanoLOCK[supreg] versus control, single versus multi-level surgery, and intra-op complication. The applicant stated that, based on the results of the MME analysis, the use of nanoLOCK[supreg] reduced total MME by MME 24.47 units (95 percent CI: 14.42 to 34.52 units) more than patients who received treatment using a control device. The applicant explained that a patient's baseline MME was also a significant predictor of MME at first follow-up when adjusted for all other variables in the model. The applicant noted that the lack of standardized registries to collect spine data, combined with the inability to access CMS registry information in advance, means that the multiple examples provided by the applicant regarding the use of nanoLOCK[supreg] are the most robust information available and the consistency in outcomes with statistical significance means the product's attributes generate clinical value. Response: We appreciate the additional data provided by the applicant. However, we are unable to determine the substantial clinical value based on the analysis' data, due in part to the vast amount of missing data and inconsistencies in the data provided. For example, at each point of follow-up the number of patients in the analysis' cohort is reduced, and ``missing'' numbers of patients in the cohort are listed. Although the analysis attempts to account for the missing patients and patients' data by pairwise deletions, we are unable to determine a consistent cohort of patients for which a possible reduction in MME usage may have occurred. We attempted to assess for a pattern of consistency with the ``missing'' data and have been unable to determine any such pattern. Additionally, while the applicant stated that it used a sample size of n=926 patients, throughout the analyses we noted varying numbers of patients for many of the variables included as covariates, making it difficult to arrive at a meaningful conclusion. We also note that the applicant did not provide further information on our concern for the selection of controls and whether there were adjustments in the statistical analyses controlling for confounding factors (for example, cause of back pain, level of experience of the surgeon, BMI and length of pain). Comment: One commenter stated that the nanoLOCK[supreg] provides a substantial clinical benefit, which is evidenced by multiple third- party analytics evaluations that were performed outside of the manufacturer's control. The commenter stated that these analytic evaluations have found that the nanoLOCK[supreg] technology has led to reduced hospital inpatient mean length of stay, fewer total readmissions over 30 days post operation, and decreased use of prescription opioids for post-operative spinal surgery patients. However, the commenter did not provide the specific third-party analytic evaluations with its public comment submission. Several commenters believed that the nanoLOCK[supreg] technology represents a substantial clinical improvement over current devices based on personal experience. One commenter stated that within its specific patient population, patients are returning to work faster, participating in more physical therapy, and reducing their use of opiate pain medications. Another commenter with personal experience with the nanoLOCK[supreg] technology also stated that substantial improvement within the fusion patient population had been recognized because of the granted access to the nano-surface technology. The commenter noted that patients are back to work earlier, starting physical therapy earlier, and require less narcotic medication after surgery compared to earlier patients who received treatment involving other fusion implants. Response: We appreciate the input and additional information from the commenters in support for the Titan Spine nanoLOCK[supreg] based on personal surgical experience and third party analytics. However, we note that the comments based on personal surgical experience were of a qualitative nature and did not contain objective data to support whether the Titan Spine nanoLOCK[supreg] meets the substantial [[Page 41326]] clinical improvement criterion. We believe that the Titan Spine nanoLock[supreg] may potentially be a viable alternative to existing technologies. However, the data provided did not show that use of nanoLock[supreg] interbody fusion devices provides a substantial clinical improvement over existing technologies. After consideration of all the information from the applicant, as well as the public comments we received, we are unable to determine if the Titan Spine nanoLOCK[supreg] represents a substantial clinical improvement over the currently available devices used for lumbar and cervical DDD treatment due to a lack of significant and meaningful data. As stated above, we remain concerned that the current data does not adequately support a sufficient association between the outcome measures of length of stay, readmission rates, and use of opioids and the use of nano-surface textures in the manufacturing of the Titan Spine nanoLOCK[supreg] device to determine that the technology represents a substantial clinical improvement over existing available options. Therefore, after consideration of all of the new technology add-on payment criteria we are not approving new technology add-on payments for the Titan Spine nanoLock[supreg] devices for FY 2019. f. ZEMDRITM (Plazomicin) Achaogen, Inc. submitted an application for new technology add-on payments for Plazomicin for FY 2019. We note that, since the publication of the proposed rule, the applicant has announced that the trade name for Plazomicin is ZEMDRITM. According to the applicant, ZEMDRITM (Plazomicin) is a next-generation aminoglycoside antibiotic, which has been found in vitro to have enhanced activity against many multi-drug resistant (MDR) gram-negative bacteria. We stated in the proposed rule that the proposed indication for the use of Plazomicin, which had not received FDA approval as of the time of the development of this proposed rule, was for the treatment of adult patients who have been diagnosed with the following infections caused by designated susceptible microorganisms: (1) Complicated urinary tract infection (cUTI), including pyelonephritis; and (2) bloodstream infections (BSIs). We indicated that the applicant stated that it expected that Plazomicin would be reserved for use in the treatment of patients who have been diagnosed with these types of infections who have limited or no alternative treatment options, and would be used only to treat infections that are proven or strongly suspected to be caused by susceptible microorganisms. The applicant received approval from the FDA on June 25, 2018, for Plazomicin with the trade name ZEMDRITM for use in the treatment of adults with cUTIs, including pyelonephritis. The applicant stated that there is a strong need for antibiotics that can treat infections caused by MDR Enterobacteriaceae, specifically carbapenem resistant Enterobacteriaceae (CRE). Life- threatening infections caused by MDR bacteria have increased over the past decade, and the patient population diagnosed with infections caused by CRE is projected to double within the next 5 years, according to the Centers for Disease Control and Prevention (CDC). Infections caused by CRE are often associated with poor patient outcomes due to limited treatment options. Patients who have been diagnosed with BSIs due to CRE face mortality rates of up to 50 percent. Patients most at risk for CRE infections are those with CRE colonization, recent hospitalization or stay in a long-term care or skilled-nursing facility, an extensive history of antibacterial use, and whose care requires invasive devices like urinary catheters, intravenous (IV) catheters, or ventilators. The applicant estimated, using data from the Center for Disease Dynamics, Economics & Policy (CDDEP), that the Medicare population that has been diagnosed with antibiotic-resistant cUTI numbers approximately 207,000 and approximately 7,000 for BSIs/ sepsis due to CRE. The applicant noted that due to the public health concern of increasing antibiotic resistance and the need for new antibiotics to effectively treat MDR infections, Plazomicin has received the following FDA designations: Breakthrough Therapy; Qualified Infectious Disease Product, Priority Review; and Fast Track. The applicant noted that Breakthrough Therapy designation was granted on May 17, 2017, for the treatment of bloodstream infections (BSIs) caused by certain Enterobacteriaceae in patients who have been diagnosed with these types of infections who have limited or no alternative treatment options. The applicant noted that Plazomicin is the first antibacterial agent to receive this designation. The applicant noted that on December 18, 2014, the FDA designated Plazomicin as a Qualified Infectious Disease Product (QIDP) for the indications of hospital-acquired bacterial pneumonia (HAPB), ventilator-associated bacterial pneumonia (VABP), and complicated urinary tract infection (cUTI), including pyelonephritis and catheter-related blood stream infections (CRBSI). The applicant noted that Fast Track designation was granted by the FDA on August 12, 2012, for the Plazomicin development program for the treatment of serious and life-threatening infections due to CRE. In the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20320), we indicated that Plazomicin had not received approval from the FDA as of the time of the development of the proposed rule. However, as noted previously, the applicant received approval from the FDA on June 25, 2018, for Plazomicin with the trade name ZEMDRITM for use in the treatment of adults with cUTIs, including pyelonephritis. We note that, for the remainder of this discussion in this final rule, the two technology names are referenced interchangeably. The applicant did not receive FDA approval for use in the treatment of BSIs. The applicant's request for approval for a unique ICD-10-PCS procedure code to identify the use of ZEMDRITM was granted, and the following procedure codes: XW033G4 (Introduction of Plazomicin anti-infective into peripheral vein, percutaneous approach, new technology group 4) and XW043G4 (Introduction of Plazomicin anti- infective into central vein, percutaneous approach, new technology group 4) are effective October 1, 2018. As discussed earlier, if a technology meets all three of the substantial similarity criteria, it would be considered substantially similar to an existing technology and would not be considered ``new'' for purposes of new technology add-on payments. With regard to the first criterion, whether a product uses the same or a similar mechanism of action to achieve a therapeutic outcome, the applicant asserted that Plazomicin does not use the same or similar mechanism of action to achieve a therapeutic outcome as any other drug assigned to the same or a different MS-DRG. The applicant stated that Plazomicin has a unique chemical structure designed to improve activity against aminoglycoside-resistant bacteria, which also are often resistant to other key classes of antibiotics, including beta-lactams and carbapenems. Bacterial resistance to aminoglycosides usually occurs through enzymatic modification by aminoglycoside modifying enzymes (AMEs) to compromise binding the target bacterial site. According to the applicant, AMEs were found in 98.6 percent of aminoglycoside nonsusceptible E. coli, Klebsiella spp, Enterobacter spp, and Proteus spp collected in 2016 U.S. surveillance [[Page 41327]] studies. Genes encoding AMEs are typically located on elements that also carry other causes of antibiotic resistance like B-lactamase and/ or carbapenemase genes. Therefore, extended spectrum beta-lactamases (ESBL) producing Enterobacteriaceae and CRE are commonly resistant to currently available aminoglycosides. According to the applicant, Plazomicin contains unique structural modifications at key positions in the molecule to overcome antibiotic resistance, specifically at the 6 and N1 positions. These side chain substituents shield Plazomicin from inactivation by AMEs, such that Plazomicin is not inactivated by any known AMEs, with the exception of N-acetyltransferase (AAC) 2'-Ia, -Ib, and -Ic, which is only found in Providencia species. According to the applicant, as an aminoglycoside, Plazomicin also is not hydrolyzed by B-lactamase enzymes like ESBLs and carbapenamases. Therefore, the applicant asserted that Plazomicin is a potent therapeutic agent for treating MDR Enterobacteriaceae, including aminoglycoside-resistant isolates, CRE strains, and ESBL-producers. The applicant asserted that the mechanism of action is new due to the unique chemical structure. With regard to the general mechanism of action against bacteria, in the proposed rule, we stated we were concerned that the mechanism of action of Plazomicin appeared to be similar to other aminoglycoside antibiotics. As with other aminoglycosides, Plazomicin is bactericidal through inhibition of bacterial protein synthesis. The applicant maintained that the structural changes to the antibiotic constitute a new mechanism of action because it allows the antibiotic to remain active despite AMEs. Additionally, the applicant stated that Plazomicin would be the first, new aminoglycoside brought to market in over 40 years. We invited public comments on whether Plazomicin's mechanism of action is new, including comments in response to our concern that its mechanism of action to eradicate bacteria (inhibition of bacterial protein synthesis) may be similar to that of other aminoglycosides, even if improvements to its structure may allow Plazomicin to be active even in the presence of common AMEs that inactivate currently marketed aminoglycosides. Comment: The applicant stated, in response to CMS' concern, that ZEMDRITM's (Plazomicin's) mechanism of action is not substantially similar to that of existing aminoglycosides because modifications in the chemical structure allow ZEMDRITM to both withstand resistance and reach the target site of action for antibacterial efficacy. The applicant indicated that ZEMDRITM is the first intravenous (IV) aminoglycoside approved by the FDA in over 35 years that uses a protein synthesis as its target site, combined with unique structural modifications that withstand bacterial resistance mechanisms that render currently marketed aminoglycosides ineffective. The applicant believed that consideration of the mechanism of action for antibiotics should include how it defends itself against inactivation by the bacteria, in addition to how it kills the bacteria because the increasing emergence of antibiotic resistance requires that new drugs not only exert bactericidal action, but also how the new drugs overcome bacterial resistance. The applicant stated that the ability of an antibiotic to withstand resistance is equally important as the ability to work at the target site because without the first action, the latter would not matter. Therefore, the applicant posited that, while ZEMDRITM's mechanism of bacterial killing is similar to other aminoglycosides, its ability to withstand antibiotic resistance due to AMEs is substantially different and represents an improvement in the treatment of patients diagnosed with serious gram-negative bacterial infections. The applicant indicated that, in the event of resistance, the antibiotic cannot kill the bacteria without further extension of mechanisms to protect against this resistance, regardless of its site of action. The applicant stated that other aminoglycosides, in contrast to ZEMDRITM, do not have the modifications that allow them to withstand common mechanisms of resistance and, thereby, cannot bind to the target site of antibacterial action and are inactive. The applicant further explained that, specifically, the structural modifications in Plazomicin protects the antibiotic from most AMEs produced by bacteria that inactivates other aminoglycosides including gentamicin, tobramycin, and amikacin. The applicant stated that ZEMDRITM inhibits 90 percent of the Enterobacteriaceae, including those resistant to one or more aminoglycoside antibiotics at a concentration of <=4 mcg/mL (the proposed breakpoint for Plazomicin). The applicant also noted that ZEMDRITM is already protected by at least four issued patents in the U.S., representing the general innovative and novel characteristics of the compound. Another commenter noted that CMS' concerns focused on commonalities between Plazomicin and other antibiotics in the same general antibiotic class, and stated that the unique benefits of this medicine should not be ignored due to the substantial similarities to other medicines, given the recognized shortage of new antibiotics. Response: We appreciate the applicant and the commenter's input regarding the technology. After consideration of the comments we received from the applicant regarding ZEMDRITM's mechanism of action, we agree that ZEMDRITM's ability to withstand antibiotic resistance is a critical component of its mechanism of action because it enables the antibiotic to effectively inhibit bacterial protein synthesis despite aminoglycoside resistance. With respect to the second criterion, whether a product is assigned to the same or a different MS-DRG, we believe that potential cases representing patients who may be eligible for treatment involving Plazomicin would be assigned to the same MS-DRGs as cases representing patients who receive treatment for UTI or bacteremia. Comment: The applicant agreed with CMS and stated that use of ZEMDRITM will not change the MS-DRG assignment for potential cases representing eligible patients. Response: We appreciate the applicant's input. We note that, the FDA approval for ZEMDRITM was only for the treatment of patients 18 years of age or older who have been diagnosed with a cUTI, including pyelonephritis, and not for the other proposed indication of bacteremia/BSI. Therefore, we are only considering the MS-DRG assignment for potential cases representing eligible patients for the approved indication. With respect to the third criterion, whether the new use of the technology involves the treatment of the same or similar type of disease and the same or similar patient population, we indicated in the proposed rule that the applicant asserted that Plazomicin is intended for use in the treatment of patients who have been diagnosed with cUTI, including pyelonephritis, and bloodstream infections, who have limited or no alternative treatment options. We stated that because the applicant anticipated that Plazomicin would be reserved for use in the treatment of patients who have limited or no alternative treatment options, the applicant believed that Plazomicin may be indicated to treat a new patient population for which no other technologies are available. However, we stated that it is possible that existing antimicrobials could also be used to treat those same bacteria Plazomicin is [[Page 41328]] intended to treat. Specifically, we indicated that the applicant was seeking FDA approval for use in the treatment of patients who have been diagnosed with cUTI, including pyelonephritis, caused by the following susceptible microorganisms: Escherichia coli (including cases with concurrent bacteremia), Klebsiella pneumoniae, Proteus spp (including P. mirabilis and P. vulgaris), and Enterobactercloacae, and for use in the treatment of patients who have been diagnosed with BSIs caused by the following susceptible microorganisms: Klebsiella pneumonia and Escherichia coli. We stated that because the susceptible organisms for which Plazomicin was proposed to be indicated include nonresistant strains that existing antibiotics may effectively treat, we were concerned that Plazomicin may not treat a new patient population. Therefore, we invited public comments on whether Plazomicin treats a new type of disease or a new patient population. We also invited public comments on whether Plazomicin is substantially similar to any existing technologies and whether it meets the newness criterion. As noted previously, Plazomicin received approval with the trade name ZEMDRITM for use in the treatment of patients 18 years of age or older with cUTI, including pyelonephritis. Comment: The applicant disagreed with CMS' concern that ZEMDRITM may not treat a new patient population, and stated that most existing antibiotics are not effective against MDR strains of bacteria, especially extended spectrum b-lactamase (ESBL)-producing Enterobacteriaceae and CRE. The applicant further stated that, because of the FDA's methodology for determining antibiotic labels and indication of bacteria, ZEMDRITM is indicated for resistant and also nonresistant strains of bacteria, but the FDA label approving ZEMDRITM for the treatment of diagnoses of cUTIs, including pyelonephritis, includes the following statement limiting the indication to a new patient population: As only limited clinical safety and efficacy data are available, reserve ZEMDRITM for use in patients who have limited or no alternative treatment options. The applicant further indicated that ZEMDRITM treats a new patient population because patients infected with pathogens that are resistant to other antibiotics include patients with infections due to CRE, which is considered ``untreatable'' or ``hard to treat'' by the CDC. The applicant emphasized that the CDC cautions that CRE infections are increasing and resistant to ``all or nearly all'' antibiotics. The applicant stated that ZEMDRITM meets CMS' criterion for newness by providing, due to its mechanism to withstand resistance and its potent activity against CRE considered by the CDC as ``untreatable'', a new treatment choice for a patient population that may not have a viable option for a cure. Several other commenters supported the approval of new technology add-on payments for Plazomicin, and believed that Plazomicin treats a new patient population with very limited treatment options. The commenters specifically indicated that there is a need for new antibiotics to combat the crisis of multi-drug resistant bacteria, especially CRE infections. The commenters stated that there at least 70,000 cases of CRE annually in the United States, and the number is expected to double in 4 years. The commenters also noted that the CDC estimates that CRE infections are associated with mortality rates of up to 50 percent and occur in the most medically vulnerable patient populations. The commenters further recommended CMS acknowledge that as these organisms are becoming resistant to last-line antibiotic drugs, clinicians frequently face infections with no realistic treatment options for patients. The commenters also indicated that the CDC identified CRE as one of the three urgent drug-resistant threats to human health, and issued warning that without urgent action more patients will be ``thrust back to a time before we had effective drugs.'' Another commenter also noted that the World Health Organization identified CRE as one of the three pathogens with the highest priority for research and development of novel antimicrobials, and stated that Plazomicin is new because it has demonstrated superiority over historic regimens for the management of invasive CRE infections. The applicant and other commenters also stated that, even with newly approved antibiotic products with activity against some CRE, development of resistance has already been reported resulting in patients having no other available treatment options. The applicant and other commenters further stated that there is a need for more than one effective antibiotic active against CRE for many reasons, including various patient characteristics such as drug allergies, source location of bacteria, and the need for two active antibiotics given at the same time--a common practice for multi-drug or pan-drug resistance. Therefore, the commenters believed that multiple antibiotic treatment options are necessary and the existence of other effective antibiotics does not preclude a new antibiotic such as ZEMDRITM from representing an improved benefit for a patient population with limited or no other available treatment options. Another commenter stated that it, generally, supported CMS' concerns regarding the substantial similarity criteria for Plazomicin. Response: We appreciate the applicant's and other commenters' input on whether ZEMDRITM treats a new patient population. We understand that antibiotic resistance poses a significant threat to human health and that clinicians seek new antibiotics to treat multi- drug resistant infections, particularly those caused by CRE. Regarding our concern that ZEMDRITM is indicated for resistant and also nonresistant strains of bacteria, we believe the FDA label approving ZEMDRITM for the treatment of adult patients diagnosed with a cUTI, including pyelonephritis, addresses this concern by reserving ZEMDRITM for use in patients who have limited or no alternative treatment options. After consideration of the public comments we received, we believe that the mechanism of action for ZEMDRITM is new, as discussed above. Therefore, we believe that ZEMDRITM is not substantially similar to any existing technologies and consequently meets the newness criterion. We consider the beginning of the newness period to commence when ZEMDRITM was approved by the FDA on June 25, 2018. With regard to the cost criterion, the applicant conducted the following analysis to demonstrate that the technology meets the cost criterion. The analyses submitted by the applicant and presented in the proposed rule and below were for the indications of cUTI and BSI because the applicant was seeking FDA approval for both indications. However, as noted earlier, the technology was only approved for use in the treatment of cUTI, including pyelonephrits. Therefore, while we summarize both analyses below, as presented in the proposed rule, we note that only the cost information related to cUTI is evaluated to demonstrate that the applicant meets the cost criterion. We stated in the proposed rule that in order to identify the range of MS-DRGs that potential cases representing patients who have been diagnosed with the specific types of infections for which the technology had been proposed to be indicated for use in the treatment of and who may be potentially eligible for treatment involving Plazomicin may map to, the applicant identified all MS-DRGs in claims that [[Page 41329]] included cases representing patients who have been diagnosed with UTI or Septicemia. The applicant searched the FY 2016 MedPAR data for claims reporting 16 ICD-10-CM diagnosis codes for UTI and 45 ICD-10-CM diagnosis codes for Septicemia and identified a total of 2,046,275 cases assigned to 702 MS-DRGs. The applicant also performed a similar analysis based on 75 percent of identified claims, which spanned 43 MS- DRGs. MS-DRG 871 (Septicemia or Severe Sepsis without Mechanical Ventilation 96+ hours with MCC) accounted for roughly 25 percent of all cases in the first analysis of the 702 MS-DRGs identified, and almost 35 percent of the cases in the second analysis of the 43 MS-DRGs identified. Other MS-DRGs with a high volume of cases based on mapping the ICD-10-CM diagnosis codes, in order of number of discharges, were: MS-DRG 872 (Septicemia or Severe Sepsis without Mechanical Ventilation 96+ hours without MCC); MS-DRG 690 (Kidney and Urinary Tract Infections without MCC); MS-DRG 689 (Kidney and Urinary Tract Infections with MCC); MS-DRG 853 (Infectious and Parasitic Diseases with O.R. Procedure with MCC); and MS-DRG 683 (Renal Failure with CC). For the cost analysis summarized in the proposed rule, the applicant calculated an average unstandardized case-weighted charge per case using 2,046,275 identified cases (100 percent of all cases) and using 1,533,449 identified cases (75 percent of all cases) of $69,414 and $63,126, respectively. The applicant removed 50 percent of the charges associated with other drugs (associated with revenue codes 025x, 026x, and 063x) from the MedPAR data because the applicant anticipated that the use of Plazomicin would reduce the charges associated with the use of some of the other drugs, noting that this was a conservative estimate because other drugs would still be required for these patients during their hospital stay. The applicant then standardized the charges and applied the 2-year inflation factor of 9.357 percent from the FY 2018 IPPS/LTCH PPS final rule (82 FR 38527) to inflate the charges from FY 2016 to FY 2018. No charges for Plazomicin were added in the analysis because the applicant explained that the anticipated price for Plazomicin had yet to be determined. Based on the FY 2018 IPPS/LTCH PPS Table 10 thresholds, the average case-weighted threshold amount was $56,996 in the first scenario utilizing 100 percent of all cases, and $55,363 in the second scenario utilizing 75 percent of all cases. The inflated average case-weighted standardized charge per case was $62,511 in the first scenario and $57,054 in the second analysis. Because the inflated average case- weighted standardized charge per case exceeded the average case- weighted threshold amount in both scenarios, the applicant maintained that the technology met the cost criterion. The applicant noted that the case-weighted threshold amount is met before including the average per patient cost of the technology in both analyses. As such, the applicant anticipated that the inclusion of the cost of Plazomicin, at any price point, would further increase charges above the average case- weighted threshold amount. The applicant also supplied additional cost analyses that we summarized in the proposed rule, directing attention at each of the two proposed indications individually; the cost analyses considered potential cases representing patients who have been diagnosed with cUTI who may be eligible for treatment involving Plazomicin separately from potential cases representing patients who have been diagnosed with BSI/ Bacteremia who may be eligible for treatment involving Plazomicin, with the cost analysis for each considering 100 percent and 75 percent of identified cases using the FY 2016 MedPAR data and the FY 2018 GROUPER Version 36. For the additional cost analyses summarized in the proposed rule, the applicant reported that, for potential cases representing patients who have been diagnosed with Bacteremia and who may be eligible for treatment involving Plazomicin, 100 percent of identified cases spanned 539 MS-DRGs, with 75 percent of the cases mapping to the following 4 MS-DRGs: 871 (Septicemia or Severe Sepsis without Mechanical Ventilation 96+ hours with MCC), 872 (Septicemia or Severe Sepsis without Mechanical Ventilation 96+ hours without MCC), 853 (Infectious and Parasitic Diseases with O.R. Procedure with MCC), and 870 (Septicemia or Severe Sepsis with Mechanical Ventilation 96+ hours). According to the applicant, for potential cases representing patients who have been diagnosed with cUTI and who may be eligible for treatment involving Plazomicin, 100 percent of identified cases mapped to 702 MS-DRGs, with 75 percent of the cases mapping to 56 MS-DRGs. Potential cases representing patients who have been diagnosed with cUTIs and who may be eligible for treatment involving Plazomicin assigned to MS-DRG 871 (Septicemia or Severe Sepsis without Mechanical Ventilation 96+ hours with MCC) accounted for approximately 18 percent of all of the cases assigned to any of the identified 56 MS-DRGs (75 percent of cases sensitivity analysis), followed by MS-DRG 690 (Kidney and Urinary Tract Infections without MCC), which comprised almost 13 percent of all of the cases assigned to any of the identified 56 MS- DRGs. Two other common MS-DRGs containing potential cases representing potential patients who may be eligible for treatment involving Plazomicin who have been diagnosed with the specific type of indicated infections for which the technology is intended to be used, using the applicant's analysis approach for UTI based on mapping the ICD-10-CM diagnosis codes were: MS-DRG 872 (Septicemia or Severe Sepsis without Mechanical Ventilation 96+ hours without MCC) and MS-DRG 689 (Kidney and Urinary Tract Infections with MCC). According to the applicant's analyses submitted prior to the FDA approval, as stated in the proposed rule, for potential cases representing patients who have been diagnosed with BSI and who may be eligible for treatment involving Plazomicin, the applicant calculated the average unstandardized case-weighted charge per case using 1,013,597 identified cases (100 percent of all cases) and using 760,332 identified cases (75 percent of all cases) of $87,144 and $67,648, respectively. The applicant applied the same methodology as the combined analysis above. Based on the FY 2018 IPPS/LTCH PPS final rule Table 10 thresholds, the average case-weighted threshold amount for potential cases representing patients who have been diagnosed with BSI assigned to the MS-DRGs identified in the sensitivity analysis was $66,568 in the first scenario utilizing 100 percent of all cases, and $61,087 in the second scenario utilizing 75 percent of all cases. The inflated average case-weighted standardized charge per case was $77,004 in the first scenario and $60,758 in the second scenario; in the 100 percent of Bacteremia cases sensitivity analysis, the final inflated case-weighted standardized charge per case exceeded the average case- weighted threshold amount for potential cases representing patients who have been diagnosed with BSI and who may be eligible for treatment involving Plazomicin assigned to the MS-DRGs identified in the sensitivity analysis by $10,436 before including costs of Plazomicin. In the 75 percent of all cases sensitivity analysis scenario, the final inflated case-weighted standardized charge per case did not [[Page 41330]] exceed the average case-weighted threshold amount for potential cases representing patients who have been diagnosed with BSI assigned to the MS-DRGs identified in the sensitivity analysis, at $329 less than the average case-weighted threshold amount. In the proposed rule, we noted that because the applicant had not yet determined pricing for Plazomicin, however, it is possible that Plazomicin may also exceed the average case-weighted threshold amount for potential cases representing patients who have been diagnosed with BSI and who may be eligible for treatment involving Plazomicin assigned to the MS-DRGs identified in the 75 percent cases sensitivity analysis. For potential cases representing patients who have been diagnosed with cUTI and who may be eligible for treatment involving Plazomicin, the applicant calculated the average unstandardized case-weighted charge per case using 100 percent of all cases and 75 percent of all cases of $59,908 and $48,907, respectively. The applicant applied the same methodology as the combined analysis above. Based on the FY 2018 IPPS/LTCH PPS final rule Table 10 thresholds, the average case-weighted threshold amount for potential cases representing patients who have been diagnosed with cUTI and who may be eligible for treatment involving Plazomicin assigned to the MS-DRGs identified in the first scenario utilizing 100 percent of all cases was $51,308, and $46,252 in the second scenario utilizing 75 percent of all cases. The inflated average case-weighted standardized charge per case was $53,868 in the first scenario and $45,185 in the second scenario. In the 100 percent of cUTI cases sensitivity analysis, the final inflated case-weighted standardized charge per case exceeded the average case-weighted threshold amount for potential cases representing patients who have been diagnosed with cUTI and who may be eligible for treatment involving Plazomicin assigned to the MS-DRGs identified in the 100 percent of all cases sensitivity analysis by $2,560 before including costs of Plazomicin. In the 75 percent of all cases scenario, the final inflated case-weighted standardized charge per case did not exceed the average case-weighted threshold amount for potential cases representing patients who have been diagnosed with cUTI and who may be eligible for treatment involving Plazomicin assigned to the MS-DRGs identified in the 75 percent sensitivity analysis, at $1,067 less than the average case-weighted threshold amount. In the proposed rule, we noted that because the applicant had not yet determined pricing for Plazomicin, however, it is possible that Plazomicin may also exceed the average case-weighted threshold amount for potential cases representing patients who have been diagnosed with cUTI and who may be eligible for treatment involving Plazomicin assigned to the MS-DRGs identified in the 75 percent of all cases sensitivity analysis if charges for Plazomicin are more than $1,067. We invited public comments on whether Plazomicin meets the cost criterion. We note that the FDA approval for ZEMDRITM was only for the treatment of adults with complicated urinary tract infections cUTI, including pyelonephritis, and not for the other proposed indication of BSI. Therefore, we are only considering the cost analysis supplied by the applicant which considered potential cases representing patients who have been diagnosed with cUTI who may be eligible for treatment involving Plazomicin. Comment: The applicant believed that ZEMDRITM met the cost criterion, but supplied additional information that included the pricing for ZEMDRITM to update the cost threshold analyses presented in the proposed rule. The applicant noted in supplemental information submitted to CMS the WAC of ZEMDRITM (which is supplied as 500mg/10ml (50mg/mL) solution in a single dose vial) is $330 per vial. The applicant indicated that the recommended dosage for ZEMDRITM is 15mg/kg, every 24 hours administered as an IV infusion based on patient weight. The applicant stated that, because each vial contains 1,000 mg of ZEMDRITM, a single vial provides the complete recommended dose for a single patient who weighs 100 kg or less. The applicant predicted that patients will typically require 3 vials for the course of treatment with ZEMDRITM per day, and the average duration of ZEMDRITM therapy is 5.5 days. Therefore, the applicant stated that the total cost of ZEMDRITM per patient is $5,445. The applicant utilized the national CCR for ``Drugs'' as listed in the FY 2018 IPPS/LTCH PPS final rule to estimate hospital charges by dividing the total cost per patient by the CCR ($5,445/0.194). The applicant also updated the cost threshold analysis including hospital charges for ZEMDRITM. The applicant's updated analysis applied only to those ICD-10-CM diagnosis codes used to identify cases representing patients who have been diagnosed with a cUTI and who may be eligible for treatment involving ZEMDRITM. The applicant included two scenarios considering 100 percent of identified cases mapping to 702 MS-DRGs and 75 percent of identified cases mapping to 56 MS-DRGs using the FY 2016 MedPAR data and the FY 2018 GROUPER Version 36. The applicant stated that, as discussed in the FY 2019 IPPS/LTCH PPS proposed rule, potential cases representing patients who have been diagnosed with cUTIs and who may be eligible for treatment involving Plazomicin assigned to MS-DRG 871 (Septicemia or Severe Sepsis without Mechanical Ventilation 96+ hours with MCC) accounted for approximately 18 percent of all of the cases assigned to any of the identified 56 MS-DRGs (75 percent of cases sensitivity analysis), followed by MS-DRG 690 (Kidney and Urinary Tract Infections without MCC), which comprised almost 13 percent of all of the cases assigned to any of the identified 56 MS-DRGs. The applicant further stated that the two other common MS-DRGs containing potential cases representing potential patients who may be eligible for treatment involving Plazomicin who have been diagnosed with the specific type of indicated infections for which the technology is intended to be used, using the applicant's analysis approach for UTI based on mapping the ICD-10-CM diagnosis codes were: MS-DRG 872 (Septicemia or Severe Sepsis without Mechanical Ventilation 96+ hours without MCC) and MS-DRG 689 (Kidney and Urinary Tract Infections with MCC). Consistent with the analysis submitted for the proposed rule, the applicant calculated the average unstandardized case-weighted charge per case using 100 percent of all cases and 75 percent of all cases of $59,908 and $48,907, respectively. Consistent with the analysis submitted for the proposed rule, based on the FY 2018 IPPS/LTCH PPS final rule Table 10 thresholds, the average case-weighted threshold amount for potential cases representing patients who have been diagnosed with a cUTI and who may be eligible for treatment involving Plazomicin assigned to the MS-DRGs identified in the first scenario utilizing 100 percent of all cases was $51,308, and $46,252 in the second scenario utilizing 75 percent of all cases. The applicant utilized the same methodology described in the FY 2019 IPPS/LTCH PPS proposed rule with the exception of adding charges for Plazomicin. The applicant removed 50 percent of the charges associated with other drugs (associated with revenue [[Page 41331]] codes 025x, 026x, and 063x), then standardized the charges and applied the 2-year inflation factor of 9.357 percent from the FY 2018 IPPS/LTCH PPS final rule (82 FR 38527) to inflate the charges from FY 2016 to FY 2018. After adding the charges for Plazomicin, the inflated average case-weighted standardized charge per case was $81,935 in the first scenario and $73,252 in the second scenario. The applicant indicated that, in the 100 percent of cUTI cases sensitivity analysis, the final inflated case-weighted standardized charge per case exceeded the average case-weighted threshold amount for potential cases representing patients who have been diagnosed with a cUTI and who may be eligible for treatment involving Plazomicin assigned to the MS-DRGs identified in the 100 percent of all cases sensitivity analysis by $30,627 after including the cost of Plazomicin. The applicant further stated that, in the 75 percent of all cases scenario, the final inflated case-weighted standardized charge per case exceeded the average case-weighted threshold amount for potential cases representing patients who have been diagnosed with a cUTI and who may be eligible for treatment involving Plazomicin assigned to the MS-DRGs identified in the 75 percent sensitivity analysis by $27,000 after including the cost of Plazomicin. In both scenarios, the final inflated case-weighted standardized charge per case exceeded the average case-weighted threshold amount and, therefore, the applicant believed that ZEMDRITM continued to meet the cost criterion. Response: We appreciate the additional information received from the applicant regarding the cost of ZEMDRITM and whether the technology meets the cost criterion. After consideration of the public comments we received, we agree that ZEMDRITM meets the cost criterion. With respect to the substantial clinical improvement criterion, the applicant asserted that Plazomicin is a next generation aminoglycoside that offers a treatment option for a patient population who have limited or no alternative treatment options. Patients who have been diagnosed with BSI or cUTI caused by MDR Enterobacteria, particularly CRE, are difficult to treat because carbapenem resistance is often accompanied by resistance to additional antibiotic classes. For example, CRE may be extensively drug resistant (XDR) or even pandrug resistant (PDR). CRE are resistant to most antibiotics, and sometimes the only treatment option available to health care providers is a last- line antibiotic (such as colistin and tigecycline) with higher toxicity. According to the applicant, Plazomicin would give the clinician an alternative treatment option for patients who have been diagnosed with MDR bacteria like CRE because it has demonstrated activity against clinical isolates that possess a broad range of resistance mechanisms, including ESBLs, carbapenemases, and aminoglycoside modifying enzymes that limit the utility of different classes of antibiotics. Plazomicin also can be used to treat patients who have been diagnosed with BSI caused by resistant pathogens, such as ESBL-producing Enterobacteriaceae, CRE, and aminoglycoside-resistant Enterobacteriaceae. The applicant maintained that Plazomicin is a substantial clinical improvement because it offers a treatment option for patients who have been diagnosed with serious bacterial infections that are resistant to current antibiotics. In the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20322), we noted that Plazomicin is not indicated exclusively for resistant bacteria, but rather for certain susceptible organisms of gram-negative bacteria, including resistant and nonresistant strains for which existing antibiotics may be effective. We stated we were concerned that the applicant focused solely on Plazomicin's activity for resistant bacteria and did not supply information demonstrating substantial clinical improvement in treating nonresistant strains in the bacteria families for which Plazomicin is indicated. We note that because the FDA approval was for the cUTI indication only, and not the BSI proposed indication, we are only summarizing comments pertaining to the cUTI indication and evaluating whether ZEMDRITM meets the substantial clinical improvement criterion for use in the treatment of cUTI. Comment: The applicant stated in response to CMS' concerns that the EPIC study evaluated the efficacy of ZEMDRITM against both susceptible and resistant organisms (ESBLs) in cUTIs against a highly potent antibiotic, meropenem. The applicant noted that, although in this study approximately 25 percent of the isolates were beta-lactamase producers (ESBL), which are resistant to commonly used antibiotics such as penicillins and cephalosporins, the remaining 75 percent were susceptible to beta-lactam antibiotics (non-ESBL). Therefore, the applicant indicated that, while ZEMDRITM's substantial clinical benefit was particularly differentiated in patients with infections due to MDR pathogens where limited or no alternative therapies are available, ZEMDRITM also demonstrated a clinical improvement in patients diagnosed with a cUTI, including acute pyelonephritis, against pathogens that are susceptible to other antibiotics. The applicant emphasized that the approved FDA label fully addresses this concern because it restricts the use of ZEMDRITM to patients diagnosed with a cUTI, including pyelonephritis, who have limited or no alternative treatment options. The applicant stated that the FDA labeling ensures that ZEMDRITM is used exclusively to treat patients diagnosed with infections due to resistant bacteria and will result in ZEMDRITM's use in the treatment of patients where the benefit outweighs the risk, which includes patients with infections due to resistant pathogens such as ESBL-producing Enterobacteriaceae, non- susceptible to other currently marketed aminoglycosides, and CRE when other antibiotics cannot be used. Response: We agree with the applicant that the FDA label addresses this concern because it restricts the use of ZEMDRITM to patients diagnosed with a cUTI, including pyelonephritis, who have limited or no alternative treatment options. The applicant stated that Plazomicin also meets the substantial clinical improvement criterion because it significantly improves clinical outcomes for a patient population compared to currently available treatment options. Specifically, the applicant asserted that Plazomicin has: (1) A mortality benefit and improved safety profile in treating patients who have been diagnosed with BSI due to CRE; and (2) statistically better outcomes at test-of-cure in patients who have been diagnosed with cUTI, including higher eradication rates for ESBL- producing pathogens, and lower rate of subsequent clinical relapses. The applicant conducted two Phase III studies, CARE and EPIC. The CARE trial compared Plazomicin to colistin, a last-line antibiotic that is a standard of care agent for patients who have been diagnosed with BSI when caused by CRE. The EPIC trial compared Plazomicin to meropenem for the treatment of patients who have been diagnosed with cUTI/acute pyelonephritis. The CARE clinical trial was a randomized, open label, multi-center Phase III study comparing the efficacy of Plazomicin against colistin in the treatment of patients who have been diagnosed with BSIs or hospital-acquired bacterial pneumonia (HABP)/ventilator-acquired bacterial pneumonia [[Page 41332]] (VABP) due to CRE. Due to the small number of enrolled patients with HAPB/VABP, however, results were only analyzed for patients who had been diagnosed with BSI due to CRE. The primary endpoint was day 28 all-cause mortality or significant disease complications. Patients were randomized to receive 7 to 14 days of IV Plazomicin or colistin, along with an adjunctive therapy of meropenem or tigecycline. All-cause mortality and significant disease complications were consistent regardless of adjunctive antibiotics received, suggesting that the difference in outcomes was driven by Plazomicin and colistin, with little impact from meropenem and tigecycline. Follow-up was done at test-of-cure (TOC; 7 days after last dose of IV study drug), end of study (EOS; day 28), and long-term follow-up (LFU; day 60). Safety analysis included all patients; microbiological modified intent-to- treat (mMITT) analysis included 17/18 Plazomicin and 20/21 colisitin patients. Baseline characteristics like age, gender, APACHE II score, infection type, baseline pathogens, creatinine clearance, and adjunctive therapy with either meropenem or tigecycline were comparable in the Plazomicin and colistin groups. According to the applicant, the following results demonstrate a reduced mortality benefit in the patients who had been diagnosed with BSI subset. All-cause mortality at day 28 in the Plazomicin group was more than 5 times less than in the colistin group and all-cause mortality or significant complications at day 28 was reduced by 39 percent in the Plazomicin group compared to the colistin group. There was a large sustained 60-day survival benefit in the patients who had been diagnosed with BSI subset, with survival approximately 70 percent in the Plazomicin group compared to 40 percent in the colistin group. Additionally, according to the applicant, faster median time to clearance of CRE bacteremia of 1.5 versus 6 days for Plazomicin versus colistin and higher rate of documented clearance by day 5 (86 percent versus 46 percent) supported the reduced mortality benefit due to faster and more sustained clearance of bacteremia and also demonstrated clinical improvement in terms of more rapid beneficial resolution of the disease. The applicant maintained that Plazomicin also represents a substantial clinical improvement in improved safety outcomes. Patients treated with Plazomicin had a lower incidence of renal events (10 percent versus 41.7 percent when compared to colistin), fewer Treatment Emergent Adverse Events (TEAEs), specifically blood creatinine increases and acute kidney injury, and approximately 30 percent fewer serious adverse events were in the Plazomicin group. According to the applicant, other substantial clinical improvements demonstrated by the CARE study for use of Plazomicin in patients who had been diagnosed with BSI included lower rate of superinfections or new infections, occurring in half as many patients treated with Plazomicin versus colistin (28.6 percent versus 66.7 percent). According to the applicant, the CARE study demonstrates decreased all-cause mortality and significantly reduced disease complications at day 28 (EOS) and day 60 for patients who had been diagnosed with BSI, in addition to a superior safety profile to colistin. However, the applicant stated that, with the achieved enrollment, this study was not powered to support formal hypothesis testing and p-values and 90 percent confidence intervals are provided for descriptive purposes. The total number of patients who had been diagnosed with BSI was 29, with 14 receiving Plazomicin and 15 receiving colistin. While we understand the difficulty enrolling a large number of patients who have been diagnosed with BSI caused by CRE due to severity of the illness and the need for administering treatment promptly, we stated in the proposed rule we were concerned that results indicating reduced mortality and treatment advantages over existing standard of care for patients who have been diagnosed with BSI due to CRE are not statistically significant due to the small sample size. Therefore, we stated that we were concerned that the results from the CARE study cannot be used to support substantial clinical improvement. Comment: A commenter agreed with CMS' assessment that results of the CARE study are not statistically significant due to the small sample size of 29 patients. Response: We appreciate the commenter's input. However, we note that, we are no longer evaluating whether ZEMDRITM meets the substantial clinical improvement criterion for use in the treatment of patients diagnosed with BSI because the FDA did not approve ZEMDRITM for that proposed indication. The EPIC clinical trial was a randomized, multi-center, multi- national, double-blind study evaluating the efficacy and safety of Plazomicin compared with meropenem in the treatment of patients who have been diagnosed with cUTI based on composite cure endpoint (achieving both microbiological eradication and clinical cure) in the microbiological modified intent-to-treat (mMITT) population. Patients received between 4 to 7 days of IV therapy, followed by optional oral therapy like levofloxacin (or any other approved oral therapy) as step down therapy for a total of 7 to 10 days of therapy. Test-of-cure (TOC) was done 15 to 19 days and late follow-up (LFU) 24 to 32 days after the first dose of IV therapy. Six hundred nine patients fulfilled inclusion criteria, and were randomized to receive either Plazomicin or meropenem, with 306 patients receiving Plazomicin and 303 patients receiving meropenem. Safety analysis included 303 (99 percent) Plazomicin patients and 301 (99.3 percent) meropenem patients. mMITT analysis included 191 (62.4 percent) Plazomicin patients and 197 (65 percent) meropenem patients; exclusion from mMITT analysis was due to lack of study-qualifying uropathogen, which were pathogens susceptible to both Plazomicin and meropenem. In the mMITT population, both groups were comparable in terms of gender, age, percentage of patients who had been diagnosed with cUTI/acute pyelonephritis (AP)/urosepsis/ bacteremia/moderate renal impairment at baseline. According to the applicant, Plazomicin successfully achieved the primary efficacy endpoint of composite cure (combined microbiological eradication and clinical cure). At the TOC visit, 81.7 percent of Plazomicin patients versus 70.1 percent of meropenem patients achieved composite cure; this was statistically significant with a 95 percent confidence interval. Plazomicin also demonstrated higher eradication rates for key resistant pathogens than meropenem at both TOC (89.4 percent versus 75.5 percent) and LFU (77 percent versus 60.4 percent), suggesting that the Plazomicin treatment benefit observed at TOC was sustained. Specifically, Plazomicin demonstrated higher eradication rates, defined as baseline uropathogen reduced to less than 104, against the most common gram-negative uropathogens, including ESBL producing (82.4 percent Plazomicin versus 75.0 percent meropenem) and aminoglycoside resistant (78.8 percent Plazomicin versus 68.6 percent meropenem) pathogens. This was statistically significant, although of note, as total numbers of Enterobacteriaceae exceeded population of mMITT (191 Plazomicin, 197 meropenem) this presumably [[Page 41333]] included patients who were otherwise excluded from the mMITT population. According to the applicant, importantly, higher microbiological eradication rates at the TOC and LFU visits were associated with a lower rate of clinical relapse at LFU for Plazomicin treated patients (3 versus 14, or 1.8 percent Plazomicin versus 7.9 percent meropenem), with majority of the meropenem failures having had asymptomatic bacteriuria; that is, positive urine cultures without clinical symptoms, at TOC (21.1 percent), suggesting that the higher microbiological eradication rate at the TOC visit in Plazomicin-treated patients decreased the risk of subsequent clinical relapse. Plazomicin decreased recurrent infection by four-fold compared to meropenem, suggesting improved patient outcomes, such as reduced need for additional therapy and re-hospitalization for patients who have been diagnosed with cUTI. The safety profile of Plazomicin compared to meropenem was similar. The applicant noted that higher bacteria eradication results for Plazomicin were not due to meropenem resistance, as only patients with isolates susceptible to both drugs were included in the study. According to the applicant, the EPIC clinical trial results demonstrate clear differentiation of Plazomicin from meropenem, an agent considered by some as a gold-standard for treatment of patients who have been diagnosed with cUTI in cases due to resistant pathogens. While the EPIC clinical trial was a non-inferiority study, the applicant contended that statistically significant improved outcomes and lower clinical relapse rates for patients treated with Plazomicin demonstrate that Plazomicin meets the substantial clinical improvement criterion for the cUTI indication. Specifically, according to the applicant, the efficacy results for Plazomicin combined with a generally favorable safety profile provide a compelling benefit-risk profile for patients who have been diagnosed with cUTI, and particularly those with infections due to resistant pathogens. Most patients enrolled in the EPIC clinical trial were from Eastern Europe. We expressed in the proposed rule that it is unclear how generalizable these results would be to patients in the United States as the susceptibilities of bacteria vary greatly by location. The applicant maintained that this is consistent with prior studies and is unlikely to have affected the results of the study because the pharmacokinetics of Plazomicin and meropenem are not expected to be affected by race or ethnicity. However, bacterial resistance can vary regionally and, in the proposed rule, we expressed that we are interested in how this data can be extrapolated to a majority of the U.S. population. Comment: A commenter agreed with CMS' concern that results from the EPIC clinical trial are predominately based on patients enrolled in trials in Eastern Europe, and it is not clear how generalizable their results would be to patients in the United States. The applicant stated that the representation of the patients enrolled in the EPIC trial was similar to other recent cUTI studies for drugs approved in the U.S., and the spectrum of diagnoses and bacteriology in these studies were representative of the epidemiology and standard-of-care used in the United States. The applicant further noted that the primary analysis excluded pathogens resistant to either study drugs (ZEMDRITM or meropenem) and, therefore, avoided imbalances due to geographic differences in resistance. The applicant also provided additional data to demonstrate that the results from the EPIC trial are generalizable to patients treated in the U.S. because the susceptibilities of bacteria to ZEMDRITM do not vary between patients in the U.S. versus patients in Eastern Europe, and the pharmacokinetic profile of ZEMDRITM or meropenem are not affected by race because ZEMDRITM and meropenem are cleared almost entirely by the kidneys rather than metabolized. The applicant further indicated that, in the Phase II study of ZEMDRITM in patients diagnosed with a cUTI (ACHN-490-009), a larger number of patients from the U.S. were enrolled and outcomes were similar to those observed in the EPIC trial. Response: We appreciate the commenter's input and the applicant's additional explanation demonstrating the results from the EPIC trial. We also stated that it is also unknown how quickly resistance to Plazomicin might develop. Additionally, we stated that the microbiological breakdown of the bacteria is unknown without the full published results, and patients outside of the mMITT population were included when the applicant reported the statistically superior microbiological eradication rates of Enterobacteriaceae at TOC. In the FY 2019 IPPS/LTCH PPS proposed rule, we stated we were concerned whether there is still statistical superiority of Plazomicin in the intended bacterial targets in the mMITT. Comment: Regarding our concern about how quickly resistance to ZEMDRITM might develop, the applicant stated that ZEMDRITM's limited use indication, the short duration of therapy, and oversight by the antimicrobial stewardship team will prevent development of resistance, which is often associated with widespread use of antibiotics. Specifically, the applicant indicated that, unlike broad spectrum antibacterial drugs, the FDA restrictions of ZEMDRITM's use helps to reduce development of resistance and is consistent with antimicrobial stewardship programs recommended by the CDC. The applicant also explained that the clinical dose of 15 mg/kg administered daily was selected to reduce the risk of emergence of resistance to ZEMDRITM. The applicant further stated that, because Plazomicin is generally not inactivated by common AMEs, the primary mechanism of resistance to Plazomicin in Enterobacteriaceae is target-site modification in isolates containing 16S-RMTases, which are rarely encountered in the U.S. and do not appear to be increasing in prevalence despite decades of clinical use of aminoglycoside class; 16S-RMTases were found in only 0.08 percent or 5 of approximately 6,500 U.S. Enterobacteriaceae isolates collected during a 2014 through 2016 surveillance study. The applicant also provided data presenting the breakdown of the uropathogens identified from baseline urine cultures in the mMITT population in the EPIC study, and clarified that statistically superior microbiological eradication rates observed with ZEMDRITM compared to meropenem at TOC (Table 2) were achieved in the same mMITT population used for the primary endpoint. Response: We appreciate the additional information received from the applicant explaining why ZEMDRITM has a low potential for development of resistance and demonstrating ZEMDRITM's statistical superiority in the intended bacterial targets in the mMITT population. Finally, because both Plazomicin and meropenem were also utilized in conjunction with levofloxacin, we stated in the proposed rule that it is unclear to us whether combined antibiotic therapy will continue to be required in clinical practice, and how levofloxacin activity or resistance might affect the clinical outcome in both patient groups. Comment: The applicant clarified that levofloxacin was provided only as an optional oral step-down therapy after pre-specified criteria in the protocol were met, consistent with recent trials of other antibiotics that have been evaluated for diagnoses of cUTIs. The [[Page 41334]] applicant explained that optional oral step-down therapy is commonly used in clinical trials of cUTIs to increase study participation by allowing patients to be discharged from the hospital following favorable response to IV therapy, rather than staying in the hospital for 10 days to receive the IV study drug. With regard to clinical practice, the applicant noted that the FDA label does not require patients to receive oral therapy following administration of ZEMDRITM, and it would be the decision of the treating physician if a patient may be switched to an oral agent following IV infusion of ZEMDRITM and the physician would determine the appropriate oral therapy, if applicable. The applicant indicated that levofloxacin did not influence the outcome of the study because it was used for a similarly short course in both the ZEMDRITM and meropenem group, and the TOC visit outcomes continued to favor ZEMDRITM in both patients who received the IV study drug only and those who received the IV study drug followed by oral therapy. Response: We appreciate the applicant's clarification regarding levoflaxin's use in clinical practice, and agree that the use of levoflaxin did not negate the study results favoring ZEMDRITM because it was used similarly in both groups and the TOC visit demonstrated improved outcomes for patients receiving only ZEMDRITM, as well as patients receiving ZEMDRITM followed by oral antibiotic therapy. We invited public comments on whether Plazomicin meets the substantial clinical improvement criterion for patients who have been diagnosed with BSI and cUTI, including with respect to whether Plazomicin constitutes a substantial clinical improvement for the treatment of patients who have been diagnosed with BSI who have limited or no alternative treatment options, and whether statistically better outcomes at test-of-cure visit, including higher eradication rates for ESBL-producing pathogens, and lower rate of subsequent clinical relapses constitute a substantial clinical improvement for patients who have been diagnosed with cUTI. Comment: The applicant and other commenters believed that ZEMDRITM represents a substantial clinical improvement for patients who have been diagnosed with a cUTI. The commenters stated that ZEMDRITM offers a substantial clinical improvement over existing aminoglycosides, both in having a higher degree of susceptibility against CRE and enhanced potency, which potentially allows safer exposures of the drug. Another commenter described some of the complications and limitations of existing therapies, including colistin, polymyxin, tigecycline, ceftolozane/tazobactam, and ceftazidime/avibactam, and the limited effectiveness of antibiotics like amikacin, and noted that ZEMDRITM provides an exciting option for transitions of care because it can be utilized in the outpatient setting and administered once-daily by IV infusion. Another commenter, generally, supported granting approval of new technology add-on payments for ZEMDRITM and stated that this next- generation aminoglycoside is a substantial innovation and advancement in the treatment of serious bacterial infections due to MDR enterobacteriaceae that commonly occur in the hospital setting. Response: We appreciate the applicant's and other commenters' input on whether ZEMDRITM offers a substantial clinical improvement over current therapies for patients who have been diagnosed with a cUTI. We believe that ZEMDRITM offers a substantial clinical improvement for patients who have limited or no alternative treatment options because it is a new antibiotic that offers a treatment option for a patient population unresponsive to currently available treatments. After consideration of the public comments we received, we have determined that ZEMDRITM meets all of the criteria for approval of new technology add-on payments. Therefore, we are approving new technology add-on payments for ZEMDRITM for FY 2019. Cases involving ZEMDRITM that are eligible for new technology add-on payments will be identified by ICD-10-PCS procedure codes XW033G4 and XW043G4. In its application, the applicant estimated that the average Medicare beneficiary would require a dosage of 15 mg/kg administered as an IV infusion as a single dose. According to the applicant, the WAC for one dose is $330, and patients will typically require 3 vials for the course of treatment with ZEMDRITM per day for an average duration of 5.5 days. Therefore, the total cost of ZEMDRITM per patient is $5,445. Under Sec. 412.88(a)(2), we limit new technology add-on payments to the lesser of 50 percent of the average cost of the technology, or 50 percent of the costs in excess of the MS- DRG payment for the case. As a result, the maximum new technology add- on payment for a case involving the use of ZEMDRITM is $2,722.50 for FY 2019. In accordance with the current ZEMDRITM label, CMS expects that ZEMDRITM will be prescribed for adult patients diagnosed with cUTIs, including pyelonephritis, who have limited or no alternative treatment options. g. GIAPREZATM The La Jolla Pharmaceutical Company submitted an application for new technology add-on payments for GIAPREZATM for FY 2019. GIAPREZATM, a synthetic human angiotensin II, is administered through intravenous infusion to raise blood pressure in adult patients who have been diagnosed with septic or other distributive shock. The applicant stated that shock is a life-threatening critical condition characterized by the inability to maintain blood flow to vital tissues due to dangerously low blood pressure (hypotension). Shock can result in organ failure and imminent death, such that mortality is measured in hours and days rather than months or years. Standard therapy for shock currently uses fluid and vasopressors to raise the mean arterial pressure (MAP). The two classes of standard of care (SOC) vasopressors are catecholamines and vasopressins. Patients do not always respond to existing standard of care therapies. Therefore, a diagnosis of shock can be a difficult and costly condition to treat. According to the applicant, 35 percent of patients who are diagnosed with shock fail to respond to standard of care treatment options using catecholamines and go on to second-line treatment, which is typically vasopressin. Eighty percent of patients on vasopressin fail to respond and have no other alternative treatment options. The applicant estimated that CMS covered charges to treat patients who are diagnosed with vasodilatory shock who fail to respond to standard of care therapy are approximately 2 to 3 times greater than the costs of other conditions, such as acute myocardial infarction, heart failure, and pneumonia. According to the applicant, one-third of patients in the intensive care unit are affected by vasodilatory shock, with 745,000 patients who have been diagnosed with shock being treated annually, of whom approximately 80 percent are septic. With respect to the newness criterion, according to the applicant, the expanded access program (EAP), or FDA authorization for the ``compassionate use'' of an investigational drug outside of a clinical trial, was initiated August 8, 2017. GIAPREZATM was granted Priority Review status and received FDA approval on December 21, 2017, for the use in the treatment of adults who have been diagnosed with septic or other distributive shock as an intravenous infusion to increase blood pressure. The [[Page 41335]] applicant submitted a request for approval for a unique ICD-10-PCS code for the administration of GIAPREZATM beginning in FY 2019 and was granted approval for the following procedure codes effective October 1, 2018: XW033H4 (Introduction of synthetic human angiotensin II into peripheral vein, percutaneous approach, new technology, group 4) and XW043H4 (Introduction of synthetic human angiotensin II into central vein, percutaneous approach, new technology group 4). As discussed above, if a technology meets all three of the substantial similarity criteria, it would be considered substantially similar to an existing technology and would not be considered ``new'' for purposes of new technology add-on payments. With regard to the first criterion, whether a product uses the same or a similar mechanism of action to achieve a therapeutic outcome, according to the applicant, GIAPREZATM is the first synthetic formulation of human angiotensin II, a naturally occurring peptide hormone in the human body. Angiotensin II is one of the major bioactive components of the renin-angiotensin-aldosterone system (RAAS), which serves as one of the body's central regulators of blood pressure. Angiotensin II increases blood pressure through vasoconstriction, increased aldosterone release, and renal control of fluid and electrolyte balance. Current therapies for the treatment of patients who have been diagnosed with shock do not leverage the RAAS. The applicant asserted that GIAPREZATM is a novel treatment with a unique mechanism of action relative to SOC treatments for patients who have been diagnosed with shock, which is adequate fluid resuscitation and vasopressors. Specifically, the two classes of SOC vasopressors are catecholamines like Norepinephrine, epinephrine, dopamine, and phenylephrine IV solutions, and vasopressins like Vasostrict[supreg] and vasopressin-sodium chloride IV solutions. Catecholamines leverage the sympathetic nervous system and vasopressin leverages the arginine-vasopressin system to regulate blood pressure. However, the third system that works to regulate blood pressure, the RAAS, is not currently leveraged by any available therapies to raise mean arterial pressure in the treatment of patients who have been diagnosed with shock. The applicant maintained that GIAPREZATM is the first synthetic human angiotensin II approved by the FDA and the only FDA-approved vasopressor that leverages the RAAS and, therefore, GIAPREZATM utilizes a different mechanism of action than currently available treatment options. The applicant explained that GIAPREZATM leverages the RAAS, which is a body system not used by existing vasopressors to raise blood pressure through inducing vasoconstriction. In the FY 2019 IPPS/ LTCH PPS proposed rule (83 FR 20325), we stated we were concerned that GIAPREZATM's general mechanism of action, increasing blood pressure by inducing vasoconstriction through binding to certain G- protein receptors to stimulate smooth muscle contraction, may be similar to that of norepinephrine, albeit leveraging a different body system. We invited public comments on whether GIAPREZATM uses a different mechanism of action to achieve a therapeutic outcome with respect to currently available treatment options, including comments or additional information regarding whether the mechanism of action used by GIAPREZATM is different from that of other treatment methods of stimulating vasoconstriction. With respect to the second criterion, whether a product is assigned to the same or a different MS-DRG, we stated in the proposed rule that we believe that potential cases representing patients who may be eligible for treatment involving GIAPREZATM would be assigned to the same MS-DRGs as cases representing patients who receive SOC treatment for a diagnosis of shock. As explained below in the discussion of the cost criterion, the applicant believed that potential cases representing patients who may be eligible for treatment involving GIAPREZATM would be assigned to MS-DRGs that contain cases representing patients who have failed to respond to administration of fluid and vasopressor therapies. With respect to the third criterion, whether the new use of the technology involves the treatment of the same or similar type of disease and the same or similar patient population, according to the applicant, once patients have failed treatment using catecholamines, treatment options for patients who have been diagnosed with severe septic or other distributive shock are limited. According to the applicant, agents that were previously available are each associated with their own adverse events (AEs). The applicant noted that primary options that have been investigated include vasopressin, corticosteroids, methylene blue, and blood purification techniques. Of these options, the applicant stated that only vasopressin has a recommendation as add on vasopressor therapy in current treatment guidelines, but the recommendations are listed as weak with moderate quality of evidence. According to the applicant, there is uncertainty regarding vasopressin's effect on mortality due to mixed clinical trial results, and higher doses of vasopressin have been associated with cardiac, digital, and splanchnic ischemia. Therefore, the applicant asserted that there is a significant unmet medical need for treatments for patients who have been diagnosed with septic or distributive shock who remain hypotensive, despite adequate fluid and vasopressor therapy and for medications that can provide catecholamine-sparing effects. The applicant also noted that there is currently no standard of care for addressing the clinical state of septic or other distributive shock experienced by patients who fail to respond to fluid and available vasopressor therapy. Additionally, according to the applicant, no clinical evidence or consensus for treatments is available. Based on the applicant's statements as summarized above, we stated in the proposed rule that it appears that the applicant is asserting that GIAPREZATM provides a new therapeutic treatment option for critically-ill patients who have been diagnosed with shock who have limited options and worsening prognosis. However, we further stated we were concerned that GIAPREZATM may not offer a treatment option to a new patient population, specifically because the FDA approval for GIAPREZATM does not reserve the use of GIAPREZATM only as a last-line drug or adjunctive therapy for a subset of the patient population who have been diagnosed with shock who have failed to respond to standard of care treatment options. According to the FDA-approved labeling, GIAPREZATM is a vasoconstrictor to increase blood pressure in adult patients who have been diagnosed with septic or other distributive shock. Patients who have been diagnosed with septic or other distributive shock are not a new patient population. Therefore, we stated that it appears that GIAPREZATM is used to treat the same or similar type of disease (a diagnosis of shock) and a similar patient population receiving SOC therapy for the treatment of shock. In the proposed rule, we invited public comments on whether GIAPREZATM meets the substantial similarity criteria and the newness criterion. Comment: The applicant indicated that GIAPREZATM is not substantially similar to existing treatment options [[Page 41336]] because it is the sole member of a new class of vasopressor peptide, and the only one that acts to leverage the renin-angiotensin- aldosterone (RAAS) system. The applicant stated that GIAPREZATM's mechanism of action is unique because GIAPREZATM operates in a fundamentally different manner than norepinephrine, in addition to leveraging a different body system. The applicant noted, specifically, that GIAPREZATM causes vasoconstriction of the smooth muscles and stimulates the release of aldosterone from the adrenal cortex to promote sodium retention by the kidneys, both of which lead to increased blood pressure. The applicant explained that, although catecholamines, vasopressin, and angiotensin II all engage G-coupled protein receptors for their function, they engage entirely different G-coupled receptors subtypes and engage different receptor targets. The applicant further described the biochemical pathways unique to angiotensin, and recommended that CMS consider the feedback mechanisms present in the classical RAAS,\123\ which enable GIAPREZATM to be more effective in the treatment of diagnosis of shock than standard-of-care vasopressors. The applicant provided literature and specific citations that suggested ACE activity is diminished in conditions associated with vasodilatory shock, which would result in a state of relative angiotensin II deficiency, that is, excess angiotensin I, similar to a state induced by ACE inhibitor treatment in patients who have been diagnosed with essential hypertension.\124\ \125\ According to the applicant, in vasodilatory shock syndromes, the addition of exogenous angiotensin II attenuates production of angiotensin I by suppressing release of renin at the juxtaglomerular apparatus, and potentially reduces angiotensin (1-7) levels, resulting in a more normalized angiotensin I to/ angiotensin II ratio and a reduced endogenous vasodilator drive. In contrast, the applicant asserted that norepinephrine is a catecholamine that functions as a peripheral vasoconstrictor by acting on alpha- adrenergic receptors and an inotropic stimulator of the heart and a dilator of coronary arteries, a result of its activity at the beta- adrenergic receptors. The applicant stated that, GIAPREZATM, however, has a non-adrenergic mechanism of action that contributes to its catecholamine-sparing effect. The applicant indicated that GIAPREZATM can be administered in combination with norepinephrine because GIAPREZATM affects vasoconstriction not by augmentation of norepinephrine, but by way of an entirely novel mechanism. --------------------------------------------------------------------------- \123\ Sparks MA, Crowley SD, Gurley SB, Mirotsou M, Coffman TM.

Cell Signal. 2014;26(10):2147-60. --------------------------------------------------------------------------- One commenter pointed out that vasoconstriction is a very general and fundamental physiologic mechanism by which blood pressure is regulated, such that it would occur with any regimen for treating patients who have been diagnosed with shock. Other commenters stated that current standard-of-care treatment options only target two of the three major biological systems regulating MAP, which makes GIAPREZATM the first and only FDA-approved synthetic human angiotensin II treatment option that activates the RAAS to increase MAP. The commenters believed that GIAPREZA TM's unique mechanism of action supports a multi- modal approach to the treatment of patients who have been diagnosed with shock that mimics the body's natural response to hypotension, and offers physicians a critical new tool for saving lives. With respect to the second criterion, the applicant indicated that there are inherent difficulties in capturing specific patient types for a condition such as a diagnosis of shock, and explained that the current structure of the MS-DRG payment system does not yet have the refined elements necessary to identify those patients likely to respond to treatment involving GIAPREZA TM. The applicant emphasized that the MS-DRGs for Septicemia or Severe Sepsis with or without Mechanical Ventilation >96 Hours are MS-DRGs that are noted frequently as being in the top 10 highest volume Medicare MS-DRGs reported overall each year. The applicant believed that medical DRGs that are driven by complications have an inherently more challenging time demonstrating uniqueness as a function of Medicare's MS-DRG GROUPER approach than the medical device population. However, the applicant stated that as the ICD-10-CM/PCS system continues to evolve and new MS-DRGs are added to capture new technologies, there will be additional opportunities to better highlight certain products' use, like GIAPREZATM, in key populations. Regarding the third criterion, the applicant contended that although the FDA approval for GIAPREZATM is not reserved exclusively for patients diagnosed with shock who have failed to respond to standard-of-care treatment options, GIAPREZATM still treats a new patient population that is a significant subset of the larger patient population for which GIAPREZATM has received FDA approval. Specifically, the applicant emphasized that, of approximately 1.12 million hypotensive patients, greater than 50 percent fail the standard-of-care treatment practice and, therefore, have no other available treatment options. The applicant believed that GIAPREZATM provides a new treatment option for Medicare beneficiaries that can be started immediately and can benefit the patient within only approximately 5 minutes. Other commenters similarly stated that GIAPREZATM fills an unmet need for new treatment options for patients who have been diagnosed with shock, considering that more than 50 percent of patients who have been diagnosed with distributive shock fail to meet MAP goals using the standard-of-care treatment options. The commenters emphasized that mortality from shock remains high, especially in patients who have been diagnosed with refractory shock, primarily due to progressive hypotension and resulting organ failure and limited treatment options. The commenters believed that GIAPREZATM offers a breakthrough treatment option that promises to save lives by providing an alternative treatment option for a subset of the shock patient population for whom there was previously no other treatment options available. In addition to the public comments summarized above regarding mechanism of action, MS-DRG assignment of potential cases eligible for treatment involving use of GIAPREZATM, and the treatment of the intended patient population, the applicant stated that prior to approval of GIAPREZATM, only two classes of vasopressors were available: Catecholamines and vasopressin, both of which have narrow therapeutic windows and significant toxic effects when administered at higher doses. The applicant further stated that catecholamines are correlated to serious complications, such as increased digital and limb necrosis \126\ and kidney injury.\127\ The applicant explained that [[Page 41337]] vasopressin was the only non-catecholamine vasopressor available to clinicians, but it fails to improve blood pressure in the majority of patients, therefore, making its impact quite limited.\128\ Additionally, the applicant indicated that vasopressin is also slow to take effect (peak effect at 15 minutes) and, therefore, is difficult to titrate, to achieve and maintain the desired MAP, which further complicates its use and leaves patients hypotensive for longer.\129\ \130\ The applicant further explained that last-resort adjuvant non- vasopressor therapies such as corticosteroids, ascorbic acid, thiamine, and methylene blue are still used in desperation, but none have been shown to reliably improve blood pressure or survival. Therefore, the applicant suggested that CMS recognize that GIAPREZATM answers an unmet need for a safe, effective, fast-acting, alternative therapy.\131\ With regard to newness, a couple of commenters stated that GIAPREZATM is the first new vasopressor approved by the FDA in over 40 years. To the contrary, another commenter stated that it, generally, supported CMS' concerns about GIAPREZATM. --------------------------------------------------------------------------- \126\ Brown SM, Lanspa MJ, Jones JP, et al.

Therefore, GIAPREZATM is not substantially similar to existing treatment options and meets the newness criterion. With regard to the cost criterion, the applicant conducted an analysis for a narrower indication, patients who have been diagnosed with refractory shock who have failed to respond to standard of care vasopressors, and an analysis for a broader indication of all patients who have been diagnosed with septic or other distributive shock. In the FY 2019 IPPS/LTCH PPS proposed rule (82 FR 20325), we stated we believed that only this broader analysis, which reflects the patient population for which the applicant's technology is approved by the FDA, is relevant to demonstrate that the technology meets the cost criterion and, therefore, we only summarized this broader analysis in the proposed rule (and below). In order to identify the range of MS-DRGs that potential cases representing potential patients who may be eligible for treatment using GIAPREZATM may map to, the applicant used two separate analyses to identify the MS-DRGs for patients who have been diagnosed with shock or related diagnoses. The applicant also performed three sensitivity analyses on the MS-DRGs for each of the two selections: 100 percent of the MS-DRGs, 80 percent of the MS-DRGs, and 25 percent of the MS-DRGs. Therefore, a total of six scenarios were included in the cost analysis. The first analysis (Scenario 1) selected the MS-DRGs most representative of the potential patient cases where treatment involving GIAPREZATM would have the greatest clinical impact and outcomes of improvement over present treatment options. The applicant searched for 28 different ICD-9-CM codes under this scenario. The second analysis (Scenario 2) used the 80 most relevant ICD-9-CM diagnosis codes based on the inclusion criteria of the GIAPREZATM Phase III clinical trial, ATHOS-3, and an additional 8 ICD-9-CM diagnosis codes for clinical presentation associated with vasodilatory or distributive shock patients failing fluid and standard of care therapy to capture any additional potential cases that may be applicable based on clinical presentations associated with this patient population. Among only the top quartile of potential patient cases, the single MS-DRG representative of most potential patient cases was MS-DRG 871 (Septicemia or Severe Sepsis without Mechanical Ventilation >96 Hours with MCC) for both ICD-9-CM diagnosis code selection scenarios, and in both selections, it accounted for a potential patient case percentage surpassing 25 percent. Because GIAPREZATM is not reserved exclusively as a last-line drug based on the FDA indication, the applicant removed 50 percent of drug charges for prior technologies or other charges associated with prior technologies from the unstandardized charges before standardization in order to account for other drugs that may be replaced by the use of GIAPREZATM. At the time of development of the proposed rule, the applicant had not yet supplied CMS with pricing for GIAPREZATM and did not include charges for the new technology when conducting this analysis. For all analyses' scenarios, the applicant standardized charges using the FY 2015 impact file and then inflated the charges to FY 2019 using an inflation factor of 15.4181 percent (or 1.154181) by multiplying the inflation factor of 1.098446 in the FY 2017 IPPS/LTCH PPS final rule (81 FR 57286) by the inflation factor of 1.05074 in the FY 2018 IPPS/ LTCH PPS final rule (82 FR 38524). The final inflated average case- weighted standardized charge per case was calculated for each scenario and compared with the average case-weighted threshold amount for each group of MS-DRGs based on the thresholds in Table 10. Results of the analyses for each of the two code selection scenarios, each with three sensitivity analyses for a total of six analyses, are summarized in the tables below: ---------------------------------------------------------------------------------------------------------------- Final average Number of MS- Case- weighted inflated Amount DRGs assessed Number of new technology standardized exceeded Medicare cases add-on payment charge per threshold threshold case ---------------------------------------------------------------------------------------------------------------- Cost Analysis Based on ICD-9-CM Diagnosis Code Scenario 1 ---------------------------------------------------------------------------------------------------------------- ICD-9-CM Diagnosis Code Selection (28 Codes): 100 Percent................. 439 120,966 $77,427 $111,522 $34,095 80 Percent.................. 10 96,102 77,641 100,167 22,526 25 Percent.................. 1 66,980 53,499 71,951 18,452 ---------------------------------------------------------------------------------------------------------------- [[Page 41338]] Cost Analysis Based on ICD-9-CM Diagnosis Code Scenario 2 ---------------------------------------------------------------------------------------------------------------- ICD-9-CM Diagnosis Code Selection (88 Codes): 100 Percent................. 466 164,892 78,675 112,174 33,499 80 Percent.................. 52 131,690 79,732 108,396 28,664 25 Percent.................. 1 67,016 53,499 71,688 18,189 ---------------------------------------------------------------------------------------------------------------- The applicant maintained that, based on the Table 10 thresholds, the inflated average case-weighted standardized charge per case in the analyses exceeded the average case-weighted threshold amount. The applicant noted that the inflated average case-weighted standardized charge per case exceeds the average case-weighted threshold amount by at least $18,189, without the average per patient cost of the technology. As such, the applicant anticipated that the inclusion of the cost of GIAPREZATM, at any price point, would further increase charges above the average case-weighted threshold amount. Therefore, the applicant stated that the technology met the cost criterion. We noted in the proposed rule that we were unsure whether the selection in both scenarios fully captures the broader indication for which the FDA approved the use of GIAPREZATM. We invited public comments on whether GIAPREZATM meets the cost criterion, including with respect to the concern we had raised. Comment: The applicant provided an updated cost analysis to broaden the patient cases according to the expanded FDA-approved indication. Specifically, the applicant stated that it removed the original exclusion criteria, which previously limited the patient cases used in the cost analysis to vasopressor-unresponsive patient cases, subjected all three ICD-9-CM code selections to a broader procedure code inclusion list, and additionally adjusted codes based on the clinical profile of diagnoses of distributive/septic shock. The applicant noted, as noted in the proposed rule, that the inflated average case-weighted standardized charge per case exceeded the average case-weighted threshold amount before including the average per patient cost of the technology. The applicant also added charges for the cost of the technology to its updated analysis. The applicant indicated that the WAC of GIAPREZATM (which is supplied as a 2.5mg/1mL vial) is $1,500 per vial. The applicant stated that, according to the FDA-approved labeling, the recommended dosage of GIAPREZATM is 20 nanograms (ng)/kg/min administered as an IV infusion, titrated as frequently as every 5 minutes by increments of up to 15 ng/kg/min, as needed. The applicant stated that, because each vial contains 2.5 mg of GIAPREZATM, a patient weighing 70 kg infused for 48 hours at a constant dose of 20ng/kg/min would use 1.6 vials of GIAPREZATM. The applicant explained that, as vials will be used in whole integers, each episode-of-care would require 2 vials and consequently would cost $3,000 per patient, per episode-of- care, at the current WAC of $1,500. To estimate the anticipated average charge submitted by hospitals for use of GIAPREZATM, the applicant stated that it used a conservative CCR of 0.5, which equated to the lower hospital markups for similar drugs. The applicant subtracted 50 percent of the costs of prior technology charges, which resulted in the final inflated average standardized charge per case, which exceeded the Table 10 average case- weighted threshold amounts by an average of $40,011, after the outlined changes were made. The applicant submitted the following table summarizing the updated cost threshold analysis: Summary of Case-Weighted Cost-Threshold Analysis Using FY 2015 MedPAR Data (50 Percent of Pharmacy Charges) Post Issuance of the FY 2019 IPPS/LTCH PPS Proposed Rule ---------------------------------------------------------------------------------------------------------------- Final inflated Case- weighted average case- Number of MS- Number of new technology weighted Amount DRGs assessed Medicare cases add-on payment standardized exceeded threshold charge per threshold case ---------------------------------------------------------------------------------------------------------------- Cost Analysis Based on ICD-9-CM Diagnosis Code Scenario 1 ---------------------------------------------------------------------------------------------------------------- ICD-9-CM Diagnosis Code Selection (41 Codes): 100 Percent................. 711 816,386 $93,312 $134,127 $40,815 80 Percent.................. 55 652,298 97,759 134,733 36,974 25 Percent.................. 1 145,043 53,499 82,947 29,448 ---------------------------------------------------------------------------------------------------------------- Cost Analysis Based on ICD-9-CM Diagnosis Code Scenario 2 ---------------------------------------------------------------------------------------------------------------- ICD-9-CM Diagnosis Code Selection (28 Codes): 100 Percent................. 499 318,168 93,324 148,143 54,819 80 Percent.................. 8 251,694 96,337 139,486 43,149 25 Percent.................. 1 145,345 53,499 82,900 29,401 ---------------------------------------------------------------------------------------------------------------- Cost Analysis Based on ICD-9-CM Diagnosis Code Scenario 3 ---------------------------------------------------------------------------------------------------------------- ICD-9-CM Diagnosis Code Selection (99 Codes): [[Page 41339]] 100 Percent................. 685 487,091 97,294 147,388 50,094 80 Percent.................. 45 388,622 103,664 149,700 46,036 25 Percent.................. 1 145,472 53,499 82,866 29,367 ---------------------------------------------------------------------------------------------------------------- Response: After consideration of the public comments we received, we agree that GIAPREZATM meets the cost criterion. With respect to the substantial clinical improvement criterion, the applicant summarized that it believes that GIAPREZATM represents a substantial clinical improvement because it: (1) Addresses an unmet medical need for patients who have been diagnosed with septic or distributive shock that, despite standard of care vasopressors, are unable to maintain adequate mean arterial pressure; (2) is the only agent shown in randomized clinical trial to rapidly and sustainably achieve or maintain target blood pressure in patients who do not respond adequately to fluid and vasopressor therapy; (3) although not powered for mortality, the ATHOS-3 trial demonstrated a strong trend to reduce the risk of death in adults from septic or distributive shock who remain hypotensive despite fluid therapy and vasopressor therapy, a severe, life-threatening condition, for which there are no other therapies; (4) provides a catecholamine-sparing effect; and (5) is generally safe and well-tolerated, with no significant differences in the percentages of patients with any grade adverse events or serious adverse events when compared to placebo. Expanding on the statements above, we stated in the proposed rule that the applicant believes that the use of GIAPREZATM offers clinicians a significant new tool to manage and treat severe hypotension in all adult patients who have been diagnosed with septic or other distributive shock who are unresponsive to existing vasopressor therapies. The applicant also stated that the use of GIAPREZATM provides a new therapeutic option for critically- ill adult patients who have been diagnosed with septic or other distributive shock who have limited options and worsening prognoses. The applicant maintained that GIAPREZATM was shown to be an effective treatment option for critically-ill patients who have been diagnosed with refractory shock. The applicant reported that a randomized, double-blind placebo controlled trial called ATHOS-3 \132\ examined the ability of GIAPREZATM to increase mean arterial pressure (MAP), with the primary endpoint being achievement of a MAP of greater than or equal to 75 mmHg (the research-backed guideline set by the Surviving Sepsis Campaign) or a 10 mmHg increase in baseline MAP. Significantly more patients in the treatment arm met the primary endpoint (69.9 percent versus 23.4 percent, P<0.001). The applicant asserted that this MAP improvement constitutes a significant substantial clinical improvement because patients treated with GIAPREZATM were three times more likely to achieve acceptable blood pressure than patients receiving the placebo. The MAP significantly and rapidly increased in patients treated with GIAPREZATM and was sustained over 48 hours consistent across subgroups and the treatment effect of GIAPREZATM was confirmed using multivariate analysis. The group treated with GIAPREZATM also experienced a greater mean increase in MAP; the MAP increased by a mean of 12.5 mmHg for the GIAPREZATM group compared to a mean of 2.9 mmHg for the placebo group. --------------------------------------------------------------------------- \132\ Khanna, A., English, S.W., Wang, X.S., et al., ``Angiotensin II for the treatment of vasodilatory shock,'' [supplementary appendix] [published online ahead of print May 21, 2017], N Engl J Med., 2017, doi: 10.1056/NEJMoa1704154. --------------------------------------------------------------------------- Second, the applicant maintained that GIAPREZATM demonstrated potential improvement in organ function by lowering the cardiovascular sequential organ failure assessment (SOFA) scores of patients at 48 hours (-1.75 GIAPREZATM group versus -1.28 placebo group). However, we stated in the proposed rule we were concerned that lower cardiovascular SOFA scores may not demonstrate substantial clinical improvement because there was no difference in the improvement of other components of the SOFA score or the overall SOFA score. Third, the applicant asserted that GIAPREZATM represents a substantial clinical improvement because the use of GIAPREZATM reduced the need to increase overall doses of catecholamine vasopressors. The applicant stated that patients receiving higher doses of catecholamine vasopressors suffer from cardiac toxicity, organ dysfunction, and other metabolic complications that are associated with higher mortality. According to the applicant, by decreasing the overall dosage of catecholamine vasopressors, GIAPREZATM potentially reduces the adverse effects of vasopressors. The mean change in catecholamine vasopressors in patients receiving GIAPREZATM versus patients receiving the placebo at 3 hours was -0.03 versus 0.03 (P<0.001), showing that GIAPREZATM allowed for catecholamines to be titrated down, while patients not receiving GIAPREZATM required additional catecholamine doses. The vasopressor mean doses were consistently lower in the GIAPREZATM group, and at 48 hours, vasopressors had been discontinued in 28.5 percent of patients in the placebo group versus 40.5 percent of the GIAPREZATM group. We noted in the proposed rule that, while GIAPREZATM may potentially reduce certain adverse effects associated with SOC treatments, the FDA- approved labeling cautions that the use of GIAPREZATM can cause dangerous blood clots with serious consequences (clots in arteries and veins, including deep venous thrombosis); according to the FDA-approved label, prophylactic treatment for blood clots should be used. In the proposed rule, we noted that the applicant stated that while the study was not powered to detect mortality effects, there was a nonsignificant trend toward longer survival in the GIAPREZATM group. Overall mortality rates at 7 days and 8 days in the modified intent to treat (MITT) population were 22 percent less in the GIAPREZATM group than in the placebo [[Page 41340]] group. At 28 days, the mortality rate in the placebo group was 54 percent versus 46 percent in the GIAPREZATM group. However, the p-values for the decrease in mortality with GIAPREZATM at 7 days, 8 days, and 28 days did not demonstrate statistical significance. The applicant concluded that GIAPREZATM is the first commercial product to increase blood pressure in adults who have been diagnosed with septic or other distributive shock that leverages the renin-angiotensin-aldosterone system. The applicant stated that the results of the ATHOS-3 study provide support for a well-tolerated new therapeutic agent that demonstrates significant improvements in mean arterial pressure. Additionally, the applicant noted that hypotension in adults who have been diagnosed with septic or other distributive shock is a prevalent life-threatening condition where therapeutic options are limited and a high unmet medical need exists. The applicant stated that the use of GIAPREZATM will represent a safe and effective new therapy that not only leverages a system that current therapies are not utilizing, but also offers a viable alternative where one does not exist. We stated in the proposed rule that we understood that, in this heterogeneous and difficult to treat patient population, studies assessing mortality as a primary endpoint are difficult, and as such, surrogate endpoints (that is, achieving baseline MAP) have been explored to assess the efficacy of treatments. While the outcomes presented by the applicant, such as achieving target MAP, lower SOFA scores, and reduced catecholamine usage, could be surrogates for clinical outcomes in these patients, we stated that there is not a strong pool of evidence connecting these single data points directly with morbidity and mortality. Therefore, in the proposed rule, we stated that we were unsure whether achieving target MAP, lower SOFA scores, and reduced catecholamine usage represents a substantial clinical improvement or instead short-term, temporary improvements without a change in overall patient prognosis. In response to this concern about MAP constituting a meaningful measure for substantial clinical improvement, the applicant supplied additional information from the current Surviving Sepsis guidelines, which recommend an initial target MAP of 65 mmHg. The applicant explained that as MAP falls below a critical threshold, inadequate tissue perfusion occurs, potentially resulting in multiple organ dysfunction and death. Therefore, early and adequate hemodynamic support and treatment of hypotension is critical to restore adequate organ perfusion and prevent worsening organ dysfunction and failure. In diagnoses of septic or distributive shock, the goal of treatment is to increase and maintain a threshold MAP in order to improve tissue perfusion. According to the applicant, tissue perfusion becomes linearly dependent on arterial pressure below a threshold MAP. In patients who have been diagnosed with septic shock requiring vasopressors, the current Surviving Sepsis guidelines are based on available evidence that demonstrates that adequate MAP is important to clinical outcomes and that prolonged decreases in MAP below 65 mmHg is associated with poor outcome. According to information supplied by the applicant, even short durations like less than 5 minutes of low MAP have been associated with severe outcomes, such as myocardial infarction, stroke, and acute kidney injury. The applicant stated that a retrospective study \133\ found that MAP was independently related to ICU and hospital mortality in patients with severe sepsis or septic shock. --------------------------------------------------------------------------- \133\ Walsh, M., Devereaux, P.J., Garg, A.X., et al., ``Relationship between Intraoperative Mean Arterial Pressure and Clinical Outcomes after Noncardiac Surgery Toward an Empirical Definition of Hypotension,'' Anesthesiology, 2013, vol. 119(3), pp. 507-515. --------------------------------------------------------------------------- Finally, we stated in the proposed rule that we were concerned that the study results may demonstrate substantial clinical improvement only for patients who are unresponsive to the administration of fluids and vasopressors because patients were only included in the ATHOS-3 study if they failed fluids and vasopressors, rather than for the broader patient population of adult patients who have been diagnosed with septic or other distributive shock for which GIAPREZATM was approved by the FDA for use as an available treatment option. We stated in the proposed rule that the applicant continues to maintain that the use of GIAPREZATM has significant efficacy in improving blood pressure for patients who have been diagnosed with distributive shock, while decreasing adrenergic vasopressor usage, thereby, providing another avenue for therapy in this difficult to treat patient population. However, we stated we were still concerned that the results from the clinical trial may be too narrow to accurately represent the entire patient population that has been diagnosed with septic or other distributive shock and, therefore, we were concerned that the clinical trial's results may not adequately demonstrate that GIAPREZATM is a substantial clinical improvement over existing therapies for all the patients for whom the treatment option is indicated. We invited public comments on whether GIAPREZATM meets the substantial clinical improvement criterion. Comment: The applicant submitted comments addressing the concerns raised by CMS in the proposed rule regarding whether GIAPREZATM meets the substantial clinical improvement criterion. With respect to the concern regarding the SOFA scores, the applicant stated that the data results, which it believes demonstrate that GIAPREZATM delivers substantial clinical improvement, are not based solely upon the observed improvements in the SOFA score. Rather, the applicant explained that SOFA is used to identify patients at a greater risk of poor outcomes. The applicant stated that the mean cardiovascular SOFA score at hour 48 showed that there was significant improvement in the GIAPREZATM group (-1.75) versus the placebo group (-1.28) (p=0.01), reflecting a higher incidence of vasopressor discontinuation prior to hour 48 and a reduced catecholamine dose in the GIAPREZATM group. The applicant also reiterated that clinical data showing GIAPREZATM's proven benefit of reducing the need for background vasopressors constitutes a substantial clinical improvement, considering the significant toxic effects of catecholamines and vasopressin administered at higher doses, including cardiac and digital ischemia; tachyarrhythmias with norepinephrine; cardiac, digital, and splanchnic ischemia; and ischemic skin lesions with vasopressin.134 135 136 137 138 139 The applicant further stated that norepinephrine (a catecholamine) is [[Page 41341]] also associated with immunosuppression, which may predispose the patient to a higher risk of secondary infections.\140\ Other commenters similarly stated that use of GIAPREZATM reduces the need for administration of these high-dose vasopressors and helps patients achieve MAP, with a significant reduction in adverse effects, unlike with the use of other vasopressors which fail to raise a patient's MAP and are associated with increases in mortality when administered at high doses; including cardiac toxicity, necrosis of the skin and distal extremities, and metabolic dysfunction. Regarding the risk of thrombosis, the applicant stated that most of the thromboembolic adverse events were of lower severity and assigned to Grade I or Grade II. The applicant further pointed out that patients who are diagnosed with vasodilatory shock are, generally, at a high risk for thrombosis, and that the FDA labeling and the immediate availability of blood- thinning agents fully address this potential safety concern. --------------------------------------------------------------------------- \134\ D[uuml]nser MW, Meier J.

The applicant also contended that the substantial clinical improvement criterion described in the September 7, 2001 final rule (66 FR 46902) identifies only a ``reduced mortality rate'' as one of a multitude of different standards and does not restrict p-values cited to a certain range to support a new technology add-on payment application determination. Therefore, the applicant believed that the p-values support the validity of the new technology add-on payment application for GIAPREZATM; they do not detract from it. Similarly, other commenters stated that GIAPREZATM is the only vasopressor to show a strong trend towards a survival benefit. The applicant also disagreed with CMS regarding our statement in the proposed rule that there is not a strong pool of evidence directly connecting target MAP, lower SOFA scores, and reduced catecholamine usage with morbidity and mortality. The applicant submitted additional evidence from the Surviving Sepsis Campaign and international and European consensus guidelines to demonstrate that maintaining an adequate MAP is a clinically meaningful benefit affecting morbidity and mortality. The applicant reiterated that when MAP drops below 60 mmHg, the human body loses autoregulatory control of blood supply to key organs,\141\ and even short durations of hypotension (<5 minutes) are associated with increased serious adverse outcomes, such as myocardial ischemia and acute kidney injury.\142\ Furthermore, the applicant cited research demonstrating that a low MAP is associated with an increased 28-day mortality, and stated that an analysis of outcomes in patients who have been diagnosed with distributive shock demonstrated a clear relationship between duration and extent of hypotension and ICU mortality.143 144 --------------------------------------------------------------------------- \141\ LeDoux D, Astiz ME, Carpati CM, Rackow EC.

The applicant further stated that, according to an analysis conducted by the applicant of outcomes based on a 50 percent reduction of the administration of catecholamine doses at 24 hours, those patients with a 50 percent reduction of administration of catecholamines doses at 24 hours had a statistically significant improved survival benefit. Additionally, the applicant indicated that the catecholamine-sparing effect resulted in significantly fewer patients experiencing a serious adverse event or a fatal event. Finally, in response to our concern that the results from the clinical trial may be too narrow to accurately represent the entire patient population that has been diagnosed with septic or other distributive shock and, therefore, may not adequately demonstrate that GIAPREZATM is a substantial clinical improvement over existing therapies for all the patients for whom the treatment option is indicated, the applicant posited that CMS' definition of substantial clinical improvement in the September 7, 2001 final rule (66 FR 46902) does not refer to the scope of FDA approval or the patient populations that that were enrolled in the clinical trial. The applicant asserted that the multitude of benefits that GIAPREZATM delivers directly pertaining to the substantial clinical improvement criterion cannot be assumed to be restricted solely to patients who have been diagnosed with refractory shock. The applicant specifically summarized the following improved outcomes: Reduced mortality rate with use of the device: A promising trend toward lower mortality was observed in the GIAPREZATM arm, and more generally, MAP >=65 mmHg is associated with decreased mortality.\145\ --------------------------------------------------------------------------- \145\ Nielsen ND, Zeng F, Gerbasi ME, Oster G, Grossman A, Shapiro NI.

Reduced recovery time: Since low MAP is associated with high ICU and 28-day mortality and GIAPREZATM achieved target MAP of 75 mmHg by hour 3 in significantly more patients than the standard-of-care, while [[Page 41342]] reducing the need for other vasopressors, GIAPREZATM may result in a shorter ICU length of stay and a faster recovery. Other commenters supported the clinical results and evidence of GIAPREZATM's meeting the substantial clinical improvement criterion, and explained that not only did the ATHOS-3 study provide compelling support for a well-tolerated new therapeutic agent that demonstrated significant improvements in MAP, it also demonstrated a strong trend toward improved survival benefit, a catecholamine-sparing effect, an increase in ICU free days, and a reduction in patients requiring renal replacement therapy (RRT). To the contrary, another commenter stated that it, generally, supported CMS' concerns. Response: We appreciate the additional information and analysis provided by the applicant and the commenters' input in response to our concerns regarding substantial clinical improvement. After reviewing the information submitted by the applicant addressing our concerns raised in the proposed rule, we agree that GIAPREZATM more rapidly allows for beneficial resolution of the disease process treatment with its shorter time to effect of only five minutes, and that GIAPREZATM has a reduced rate of device-related complications by reducing the need for background vasopressors, the utilization of which is correlated to serious complications. Specifically, we agree with the commenters and the applicant that a reduction in high-dose SOC catecholamines and vasopressin, which can be toxic and have numerous adverse effects, constitutes a substantial clinical improvement. We also agree with the applicant that the FDA- approved label, which cautions that prophylactic treatment for blood clots should be used, addresses the potential safety concern of thrombosis for patients treated with GIAPREZATM. Based on the data provided by the applicant and consideration of the public comments we received, we agree with the applicant and the commenters that GIAPREZATM represents a substantial clinical improvement over existing technologies because it quickly and effectively raises MAP while allowing for a reduction in other vasopressors. After consideration of the public comments we received, we have determined that GIAPREZATM meets all of the criteria for approval for new technology add-on payments. Therefore, we are approving new technology add-on payments for GIAPREZATM for FY 2019. Cases involving the use of GIAPREZATM that are eligible for new technology add-on payments will be identified by ICD- 10-PCS procedure codes XW033H4 and XW043H4. In its application, the applicant estimated that the average Medicare beneficiary would require a dosage of 20ng/kg/min administered as an IV infusion over 48 hours, which would require 2 vials. The applicant explained that the WAC for one vial is $1,500, with each episode-of-care costing $3,000 per patient. Under Sec. 412.88(a)(2), we limit new technology add-on payments to the lesser of 50 percent of the average cost of the technology, or 50 percent of the costs in excess of the MS-DRG payment for the case. As a result, the maximum new technology add-on payment for a case involving the use of GIAPREZATM is $1,500 for FY 2019. h. Cerebral Protection System (Sentinel[supreg] Cerebral Protection System) Claret Medical, Inc. submitted an application for new technology add-on payments for the Cerebral Protection System (Sentinel[supreg] Cerebral Protection System) for FY 2019. According to the applicant, the Sentinel Cerebral Protection System is indicated for the use as an embolic protection (EP) device to capture and remove thrombus and debris while performing transcatheter aortic valve replacement (TAVR) procedures. The device is percutaneously delivered via the right radial artery and is removed upon completion of the TAVR procedure. The De Novo request for the Sentinel[supreg] Cerebral Protection System was granted by FDA on June 1, 2017 (DEN160043). Aortic stenosis (AS) is a narrowing of the aortic valve opening. AS restricts blood flow from the left ventricle to the aorta and may also affect the pressure in the left atrium. The most common presenting symptoms of AS include dyspnea on exertion or decreased exercise tolerance, exertional dizziness (presyncope) or syncope and exertional angina. Symptoms experienced by patients who have been diagnosed with AS and normal left ventricular systolic function rarely occur until stenosis is severe (defined as valve area is less than 1.0 cm2, the jet velocity is over 4.0 m/sec, and/or the mean transvalvular gradient is greater than or equal to 40 mmHg).\150\ AS is a common valvular disorder in elderly patients. The prevalence of AS increases with age, and some degree of valvular calcification is present in 75 percent of patients who are 85 to 86 years old.\151\ TAVR procedures are the standard of care treatment for patients who have been diagnosed with severe AS. Patients undergoing TAVR procedures are often older, frail, and may be affected by multiple comorbidities, implying a significant risk for thromboembolic cerebrovascular events.\152\ Embolic ischemic strokes can occur in patients undergoing surgical and interventional cardiovascular procedures, such as stenting (carotid, coronary, peripheral), catheter ablation for atrial fibrillation, endovascular stent grafting, left atrial appendage closure (LAAO), patent formal ovale (PFO) closure, balloon aortic valvuloplasty, surgical valve replacement (SAVR), and TAVR. Clinically overt stroke, or silent ischemic cerebral infarctions, associated with the TAVR procedure, may result from a variety of causes, including mechanical manipulation of instruments or other interventional devices used during the procedure. These mechanical manipulations are caused by, but not limited to, the placement of a relatively large bore delivery catheter in the aortic arch, balloon valvuloplasty, valve positioning, valve re-positioning, valve expansion, and corrective catheter manipulation, as well as use of guidewires and guiding or diagnostic catheters required for proper positioning of the TAVR device. The magnitude and timing of embolic activity resulting from these manipulations was studied by Szeto, et al.\153\ using a transcranial Doppler, and it was found that embolic material is liberated throughout the TAVR procedure with some of the emboli reaching the central nervous system leading to cerebral ischemic infarctions. Some of the cerebral ischemic infarctions lead to neurologic injury and clinically apparent stroke. Szeto, et al. also noted that the rate of silent ischemic cerebral infarctions following TAVR procedures is estimated to be between 68 and 91 percent.154 155 --------------------------------------------------------------------------- \150\ Otto, C., Gaasch, W., ``Clinical manifestations and diagnosis of aortic stenosis in adults,'' In S.

During a TAVR procedure the prosthetic aortic valve is placed within the diseased native valve. The prosthetic valve then becomes the functioning aortic valve. As previously outlined, stroke is one of the risks associated with TAVR procedures. According to the applicant, the risk of stroke is highest in the early post-procedure period and, as previously outlined, is likely due to mechanical factors occurring during the TAVR procedure.\156\ Emboli can be generated as wire-guided devices are manipulated within atherosclerotic vessels, or when calcified valve leaflets are traversed and then crushed during valvuloplasty and subsequent valve deployment.\157\ Stroke rates in patients evaluated 30 days after TAVR procedures range from 1.0 percent to 9.6 percent \158\, and have been associated with increased mortality. Additionally, new ``silent infarcts,'' assessed via diffusion-weighted magnetic resonance imaging (DW-MRI), have been found in a majority of patients after TAVR procedures.\159\ --------------------------------------------------------------------------- \156\ Nombela-Franco, L., et al., ``Timing, predictive factors, and prognostic value of cerebrovascular events in a large cohort of patients undergoing transcatheter aortic valve implantation,'' Circulation, 2012, vol. 126(25), pp. 3041-53. \157\ Freeman, M., et al., ``Cerebral events and protection during transcatheter aortic valve replacement,'' Catheterization and Cardiovascular Interventions, 2014, vol. 84(6), pp. 885-896. \158\ Haussig, S., Linke, A., ``Transcatheter aortic valve replacement indications should be expanded to lower-risk and younger patients,'' Circulation, 2014. vol. 130(25), pp. 2321-31. \159\ Kahlert, P., et al., ``Silent and apparent cerebral ischemia after percutaneous transfemoral aortic valve implantation: a diffusion-weighted magnetic resonance imaging study,'' Circulation, 2010, vol. 121(7), pp. 870-8. --------------------------------------------------------------------------- As stated earlier, the De Novo request for the Sentinel[supreg] Cerebral Protection System was granted by FDA on June 1, 2017. The FDA concluded that this device should be classified into Class II (moderate risk). Effective October 1, 2016, ICD-10-PCS Section ``X'' code X2A5312 (Cerebral embolic filtration, dual filter in innominate artery and left common carotid artery, percutaneous approach) was approved to identify cases involving TAVR procedures using the Sentinel[supreg] Cerebral Protection System. As discussed earlier, if a technology meets all three of the substantial similarity criteria, it would be considered substantially similar to an existing technology and would not be considered ``new'' for purposes of new technology add-on payments. With regard to the first criterion, whether a product uses the same or a similar mechanism of action to achieve a therapeutic outcome, according to the applicant, the Sentinel[supreg] Cerebral Protection System device is inserted at the beginning of the TAVR procedure, via a small tube inserted through a puncture in the right wrist. Next, using a minimally invasive catheter, two small filters are placed in the brachiocephalic and left common carotid arteries. The filters collect debris, preventing it from becoming emboli, which can travel to the brain. These emboli, if left uncaptured, can cause cerebral ischemic lesions, often referred to as silent ischemic cerebral infarctions, potentially leading to cognitive decline or clinically overt stroke. At the completion of the TAVR procedure, the filters, along with the collected debris, are removed. The applicant stated that there are no other similar products for commercial sale available in the United States for cerebral protection during TAVR procedures. Two neuroprotection devices, the TriguardTM Cerebral Protection Device (Keystone Heart, Herzliya Pituach, Israel) and the Embrella Embolic DeflectorTM System (Edwards Lifesciences, Irvine, CA) are used in Europe. These devices work by deflecting embolic debris distally, rather than capturing and removing debris with filters. With respect to the second criterion, whether a product is assigned to the same or a different MS-DRG, as stated earlier, the Sentinel[supreg] Cerebral Protection System is an EP device used to capture and remove thrombus and debris while performing TAVR procedures. Therefore, potential cases representing patients who may be eligible for treatment involving this device would map to the same MS- DRGs as cases involving TAVR procedures. With respect to the third criterion, whether the new use of the technology involves the treatment of the same or similar type of disease and the same or similar patient population, according to the applicant, this technology will be used to treat patients who have been diagnosed with severe aortic valve stenosis who are eligible for a TAVR procedure. The applicant asserted that there are currently no approved alternative treatment options for cerebral protection during TAVR procedures, and the Sentinel[supreg] Cerebral Protection System is the first and only embolic protection device for use during TAVR procedures and, therefore, meets the newness criterion. The applicant also asserted that the device meets the newness criterion, as evidenced by the FDA's granting of the De Novo request and there was no predicate device. Based on the above, we stated in the proposed rule that it appears that the Sentinel[supreg] Cerebral Protection System is not substantially similar to other existing technologies. We invited public comments on whether the Sentinel[supreg] Cerebral Protection System is substantially similar to any existing technology and whether it meets the newness criterion. Comment: Several commenters agreed with CMS' assessment that the Sentinel[supreg] Cerebral Protection System is not substantially similar to other existing technologies. Response: After consideration of the public comments we received, we believe the Sentinel[supreg] Cerebral Protection System is not substantially similar to other existing technologies because it is the only neuro protective device available in the U.S. that has been granted a De Novo request by the FDA. Therefore, we believe that the Sentinel[supreg] Cerebral Protection System meets the newness criterion. The applicant conducted the following analysis to demonstrate that the technology meets the cost criterion. The applicant searched the FY 2016 MedPAR file for cases with the following ICD-10-CM procedure codes to identify cases involving TAVR procedures, which are potential cases representing patients who may be eligible for treatment involving use of the Sentinel[supreg] Cerebral Protection System: 02RF37Z (Replacement of aortic valve with autologous tissue substitute, percutaneous approach); 02RF38Z (Replacement of aortic valve with zooplastic tissue, percutaneous approach); 02RF3JZ (Replacement of aortic valve with synthetic substitute, percutaneous approach); 02RF3KZ (Replacement of aortic valve with nonautologous tissue substitute, percutaneous approach); 02RF37H (Replacement of aortic valve with autologous tissue substitute, transapical, percutaneous approach); 02RF38H (Replacement of aortic valve with zooplastic tissue, transapical, percutaneous approach); 02RF3JH (Replacement of aortic valve with synthetic substitute, transapical, percutaneous approach); and 02RF3KH (Replacement of aortic valve with nonautologous tissue substitute, transapical, percutaneous approach). This process resulted in 26,012 potential cases. The applicant limited its search to MS-DRG 266 (Endovascular Cardiac Valve Replacement with MCC) and MS-DRG [[Page 41344]] 267 (Endovascular Cardiac Valve Replacement without MCC) because these two MS-DRGs accounted for 97.4 percent of the total cases identified. Using the 26,012 identified cases, the applicant determined that the average unstandardized case-weighted charge per case was $211,261. No charges were removed for the prior technology because the device is used to capture and remove thrombus and debris while performing TAVR procedures. The applicant then standardized the charges, but did not inflate the charges. The applicant then added charges for the new technology to the average case-weighted standardized charges per case by taking the cost of the device and dividing the amount by the CCR of 0.332 for implantable devices from the FY 2018 IPPS/LTCH PPS final rule (82 FR 38103). The applicant calculated a final inflated average case- weighted standardized charge per case of $187,707 and a Table 10 average case-weighted threshold amount of $170,503. Because the final inflated average case-weighted standardized charge per case exceeded the average case-weighted threshold amount, the applicant maintained that the technology met the cost criterion. We invited public comments on whether the Sentinel[supreg] Cerebral Protection System meets the cost criterion. Comment: The applicant reiterated that the Sentinel[supreg] Cerebral Protection System meets the cost criterion. Response: We appreciate the applicant's input. After consideration of the public comment we received and reviewing the cost data and data analysis submitted by the applicant, we agree that the Sentinel[supreg] Cerebral Protection System meets the cost criterion. With regard to the substantial clinical improvement criterion, the applicant asserted that the Sentinel[supreg] Cerebral Protection System represents a substantial clinical improvement over existing technologies because it is the first and only cerebral embolic protection device commercially available in the United States for use during TAVR procedures. The applicant stated that the data below shows that the Sentinel[supreg] Cerebral Protection System effectively captures brain bound embolic debris and significantly improves clinical outcomes (that is, stroke) beyond the current standard of care, that is, TAVR procedures with no embolic protection. The applicant provided the results of four key studies: (1) The SENTINEL[supreg] study\160\ conducted by Claret Medical, Inc.; (2) the CLEAN-TAVI trial \161\; (3) the Ulm real-world registry \162\; and (4) the MISTRAL-C study.\163\ The applicant reported that the SENTINEL[supreg] study was a prospective, single blind, multi-center, randomized study using the Sentinel[supreg] Cerebral Protection System which enrolled patients who had been diagnosed with severe symptomatic calcified native aortic valve stenosis indicated for a TAVR procedure. A total of 363 patients at 19 centers in the United States and Germany were randomized across 3 arms (Safety, Test, and Control) in a 1:1:1 fashion. According to the applicant, evaluations performed for patients in each arm were as follows: --------------------------------------------------------------------------- \160\ Kapadia, S., Kodali, S., Makkar, R., et al., ``Protection against cerebral embolism during transcatheter aortic valve replacement,'' JACC, 2017, vol. 69(4), pp. 367-377. \161\ Haussig, S., Mangner, N., Dwyer, M.G., et al., ``Effect of a Cerebral Protection Device on Brain Lesions Following Transcatheter Aortic Valve Implantation in Patients With Severe Aortic Stenosis: The CLEAN-TAVI Randomized Clinical Trial,'' JAMA, 2016, vol. 316, pp. 592-601. \162\ Seeger, J., et al., ``Cerebral Embolic Protection During Transfemoral Aortic Valve Replacement Significantly Reduces Death and Stroke Compared With Unprotected Procedures,'' JACC Cardiovasc Interv, 2017. \163\ Mieghem, Van, et al., ``Filter-based cerebral embolic protection with transcatheter aortic valve implantation: the randomized MISTRAL-C trial,'' Eurointervention, 2016, vol. 12(4), pp. 499-507. --------------------------------------------------------------------------- Safety Arm patients who underwent a TAVR procedure involving the Sentinel[supreg] Cerebral Protection System--Patients enrolled in this arm of the study received safety follow-up at discharge, at 30 days and 90 days post-procedure; and neurological evaluation at baseline, discharge, 30 days and 90 days (only in the case of a stroke experienced less than or equal to 30 days) post- procedure. The Safety Arm patients did not undergo MRI or neurocognitive assessments. Test Arm patients who underwent a TAVR procedure involving the Sentinel[supreg] Cerebral Protection System--Patients enrolled in this arm of the study underwent safety follow-up at discharge, at 30 days and 90 days post-procedure; MRI assessment for efficacy at baseline, 2 to 7 days and 30 days post-procedure; neurological evaluation at baseline, discharge, 30 days and 90 days (only in the case of a stroke experienced less than or equal to 30 days) post- procedure; neurocognitive evaluation at baseline, 2 to 7 days (optional), 30 days and 90 days post-procedure; Quality of Life assessment at baseline, 30 days and 90 days; and histopathological evaluation of debris captured in the Sentinel[supreg] Cerebral Protection System's device filters. Control Arm patients who underwent a TAVR procedure only-- Patients enrolled in this arm of the study underwent safety follow-up at discharge, at 30 days and 90 days post-procedure; MRI assessment for efficacy at baseline, 2 to 7 days and 30 days post-procedure; neurological evaluation at baseline, discharge, 30 days and 90 days (only in the case of a stroke experienced less than or equal to 30 days) post-procedure; neurocognitive evaluation at baseline, 2 to 7 days (optional), 30 days and 90 days post-procedure; and Quality of Life assessment at baseline, 30 days and 90 days. The primary safety endpoint was occurrence of major adverse cardiac and cerebrovascular events (MACCE) at 30 days compared with a historical performance goal. MACCE was defined as follows: All causes of death; all strokes (disabling and nondisabling, Valve Academic Research Consortium-2 (VARC-2)); and acute kidney injury (stage 3, VARC-2). The point estimate for the historical performance goal for the primary safety endpoint at 30 days post-TAVR procedure was derived from a review of published reports of 30-day TAVR procedure outcomes. The VARC-2 established an independent collaboration between academic research organizations and specialty societies (cardiology and cardiac surgery) in the United States and Europe to create consistent endpoint definitions and consensus recommendations for implementation in TAVR procedure clinical research.\164\ --------------------------------------------------------------------------- \164\ Leon, M.B., Piazza, N., Nikolsky, E., et al., ``Standardized endpoint definitions for transcatheter aortic valve implantation clinical trials: a consensus report from the Valve Academic Research Consortium,'' European Heart Journal, 2011, vol. 32(2), pp. 205-217, doi:10.1093/eurheartj/ehq406. --------------------------------------------------------------------------- The applicant reported that results of the SENTINEL[supreg] study demonstrated the following: The rate of MACCE was numerically lower than the control arm, 7.3 percent versus 9.9 percent, but was not statistically significant from that of the control group (p=0.41). New lesion volume was 178.0 mm\3\ in control patients and 102.8 mm\3\ in the Sentinel[supreg] Cerebral Protection System device arm (p=0.33). A post-hoc multi-variable analysis identified preexisting lesion volume and valve type as predictors of new lesion volume. Strokes experienced at 30 days were 9.1 percent in control patients and 5.6 percent in patients treated with the Sentinel[supreg] Cerebral Protection System devices (p=0.25). Neurocognitive function was similar in control patients [[Page 41345]] and patients treated with the Sentinel[supreg] Cerebral Protection System devices, but there was a correlation between lesion volume and neurocognitive decline (p=0.0022). Debris was found within filters in 99 percent of patients and included thrombus, calcification, valve tissue, artery wall, and foreign material. The applicant also noted that the post-hoc analysis of these data demonstrated that there was a 63 percent reduction in 72- hour stroke rate (compared to control), p=0.05. According to the applicant, the CLEAN-TAVI (Claret Embolic Protection and TAVI) trial, was a small, randomized, double-blind, controlled trial. The trial consisted of 100 patients assigned to either EP (n=50) with the Claret Medical, Inc. device (the Sentinel[supreg] Cerebral Protection System) or to no EP (n=50). Patients were all treated with femoral access and self-expandable (SE) devices. The study endpoint was the number of brain lesions at 2 days post-procedure versus baseline. Patients were evaluated with DW-MRI at 2 and 7 days post-TAVR procedure. The mean age of patients was 80 years old; 43 percent were male. The study results showed that patients treated with the Sentinel[supreg] Cerebral Protection System had a lower number of new lesions (4.00) than patients in the control group (10.0); (p<0.001). According to the applicant, the single-center Ulm study, a large propensity matched trial, with 802 consecutive patients, occurred at the University of Ulm between 2014 and 2016. The first 522 patients (65.1 percent of patients) underwent a TAVR procedure without EPs, and the subsequent 280 patients (34.9 percent of patients) underwent a TAVR procedure with EP involving the Sentinel[supreg] Cerebral Protection System. For both arms of the study, a TAVR procedure was performed in identical settings except without cerebral EP, and neurological follow- up was performed within 7 days post-procedure. The primary endpoint was a composite of all-cause mortality or all-stroke according to the VARC- 2 criteria within 7 days. The authors who documented the study noted the following: Patient baseline characteristics and aortic valve parameters were similar between groups, that both filters of the device were successfully positioned in 280 patients, all neurological follow- up was completed by the 7th post-procedure date, and that propensity score matching was performed to account for possible confounders. Results indicated a decreased rate of disabling and nondisabling stroke at 7 days post-procedure was seen in those patients who were treated with the Sentinel[supreg] Cerebral Protection System device versus control patients (1.6 percent versus 4.6 percent, p=0.03). At 48 hours, stroke rates were lower with patients treated with the Sentinel[supreg] Cerebral Protection System device versus control patients (1.1 percent versus 3.6 percent, p=0.03). In multi-variate analysis, TAVR procedures performed without the use of a EP device was found to be an independent predictor of stroke within 7 days (p=0.04). The aim of the MISTRAL-C study was to determine if the Sentinel[supreg] Cerebral Protection System affects new brain lesions and neurocognitive performance after TAVR procedures. The study was designed as a multi-center, double-blind, randomized trial enrolling patients who were diagnosed with symptomatic severe aortic stenosis and 1:1 randomization to TAVI patients treated with or without the Sentinel[supreg] Cerebral Protection System. From January 2013 to August 2015, 65 patients were enrolled in the study. Patients ranged in age from 77 years old to 86 years old, 15 (47 percent) were female and 17 (53 percent) were male patients randomized to the Sentinel[supreg] Cerebral Protection System group and 16 (49 percent) were female and 17 (51 percent) were male patients randomized to the control group. There were 3 mortalities between 5 days and 6 months post-procedure for the Sentinel[supreg] Cerebral Protection System group. There were no strokes reported for the Sentinel[supreg] Cerebral Protection System group. There were 7 mortalities between 5 days and 6 months post- procedure for the control group. There were 2 strokes reported for the control group. Patients underwent DW-MRI and neurological examination, including neurocognitive testing 1 day before and 5 to 7 days after TAVI. Follow-up DW-MRI and neurocognitive testing was completed in 57 percent of TAVI patients treated with the Sentinel[supreg] Cerebral Protection System and 80 percent for the group of TAVI patients treated without the Sentinel[supreg] Cerebral Protection System. New brain lesions were found in 78 percent of the patients with follow-up MRI. According to the applicant, patients treated with the Sentinel[supreg] Cerebral Protection System had numerically fewer new lesions and a smaller total lesion volume (95 mm3 versus 197 mm3). Overall, 27 percent of the patients treated with the Sentinel[supreg] Cerebral Protection System and 13 percent of the patients treated in the control group had no new lesions. Ten or more new brain lesions were found only in the patients treated in the control group (20 percent in the control group versus 0 percent in the Sentinel[supreg] Cerebral Protection System group, p=0.03). Neurocognitive deterioration was present in 4 percent of the patients treated with the Sentinel[supreg] Cerebral Protection System versus 27 percent of the patients treated without (p=0.017). The filters captured debris in all of the patients treated with Sentinel[supreg] Cerebral Protection System device. In the Ulm study, the primary outcome was a composite of all-cause mortality or stroke at 7 days, and occurred in 2.1 percent of the Sentinel[supreg] Cerebral Protection System group versus 6.8 percent of the control group (p=0.01, number needed to treat (NNT)=21). Use of the Sentinel[supreg] Cerebral Protection System device was associated with a 2.2 percent absolute risk reduction in mortality with NNT 45. Composite endpoint of major adverse cardiac and cerebrovascular events (MACCE) was found in 2.1 percent of those patients undergoing a TAVR procedure with the use of the Sentinel[supreg] Cerebral Protection System device versus 7.9 percent in the control group (p=0.01). Similar but statistically nonsignificant trends were found in the SENTINEL[supreg] study, with rate of MACCE of 7.3 percent in the Sentinel[supreg] Cerebral Protection System group versus 9.9 percent in the control group (p=0.41). The applicant reported that the four studies discussed above that evaluated the Sentinel[supreg] Cerebral Protection System device have limitations because they are either small, nonrandomized and/or had significant loss to follow-up. In the proposed rule, we stated that a meta-analysis of EP device studies, the majority of which included use of the Sentinel[supreg] Cerebral Protection System device, found that use of cerebral EP devices was associated with a nonsignificant reduction in stroke and death.\165\ After further review, we realize we misquoted the statement made in the study. The meta-analysis from 2016 actually concluded the following: ``Although the differences in overt stroke were not significant, use of intraoperative EP was associated with a numeric stroke reduction, which may become significant in larger RCTs powered for hard endpoints.'' We note that we provide an updated discussion of this meta-analysis in our response to comments below. --------------------------------------------------------------------------- \165\ Giustino, G., et al., ``Neurological Outcomes With Embolic Protection Devices in Patients Undergoing Transcatheter Aortic Valve Replacement,'' Journal of the American College of Cardiology: Cardiovascular Interventions, 2016, vol. 9(20), pp. 2124-2133. --------------------------------------------------------------------------- In the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20338), we stated [[Page 41346]] we were concerned that the use of cerebral protection devices may not be associated with a significant reduction in stroke and death. We noted that the SENTINEL[supreg] study, although a randomized study, did not meet its primary endpoint, as illustrated by nonstatistically significant reduction in new lesion volume on MRI or nondisabling strokes within 30 days (5.6 percent stroke rate in the Sentinel[supreg] Cerebral Protection System device group versus a 9.1 percent stroke rate in the control group at 30 days; p=0.25). We also noted that only with a post-hoc analysis of the SENTINEL[supreg] study data were promising trends noted, where the device use was associated with a 63 percent reduction in stroke events at 72 hours (p=0.05). Additionally, although there was a statistically significant difference between the patients treated with and without cerebral embolic protection in the composite of all-cause mortality or stroke at 7 days, the Ulm study was a nonrandomized study and propensity matching was performed during analyses. We stated we are concerned that studies involving the Sentinel[supreg] Cerebral Protection System may be inconclusive regarding whether the device represents a substantial clinical improvement for patients undergoing TAVR procedures. We also stated we are concerned that the SENTINEL[supreg] studies did not show a substantial decrease in neurological complications for patients undergoing TAVR procedures. We invited public comments on whether the Sentinel[supreg] Cerebral Protection System meets the substantial clinical improvement criterion. Comment: The applicant submitted comments in response to the concerns we raised in the proposed rule. Specifically, in the proposed rule, we noted the following: The SENTINEL[supreg] study, although a randomized study, did not meet its primary endpoint as illustrated by non-statistically significant reduction in new lesion volume on MRI or non-disabling strokes within 30 days (5.6 percent stroke rate in the Sentinel[supreg] Cerebral Protection System device group versus a 9.1 percent stroke rate in the control group at 30 days; p=0.25). Only with a post-hoc analysis of the SENTINEL[supreg] study data were promising trends noted where the device use was associated with a 63 percent reduction in stroke events at 72 hours (p=0.05). With regard to the above, the applicant responded and explained the following with respect to the SENTINEL[supreg] trial: The SENTINEL[supreg] trial's success criteria were designed with two primary efficacy endpoints that were a surrogate imaging endpoint combination of: (1) Observed reduction of 30 percent in new lesion volume on MRI; and (2) statistical reduction in new lesion volume on MRI. The applicant indicated that the trial was successful in demonstrating a 42 percent reduction in new lesion volume, but as CMS pointed out, it did not, on its own, reach statistical significance, which the applicant stated was because of, in part, the surrogate nature of the endpoint as well as the higher than expected variability. The applicant noted that the variability resulted from the following sources: (1) Variability in the MRI data, in part due to the variability in the allowed time window of 2 to 7 days, logistics of scheduling follow-up MRIs within this time window for elderly patients, and the transient nature of the DW-MRI signal over time which made the signal decay rate very noisy; (2) variability due to multiplicity (total of four types) of TAVR valve types (including balloon expandable and self-expanding) introduced mid-course into the trial (the trial was powered for only two types of TAVR valves originally), which behaved differently and required different procedural parameters in terms of pre-dilatation or post-dilatation and repositioning; and (3) variability in the patient baseline lesion volumes burden or white matter disease, which was unaccounted for because this was new science generated as a result of this trial \166\ that has now been published, and a related manuscript \167\ submitted and in review. --------------------------------------------------------------------------- \166\ Lazar, R., et al., ``Neurocognition and Cerebral Lesion Burden in High-Risk Patients Before Undergoing Transcatheter Aortic Valve Replacement: Insights From the SENTINEL Trial,'' J Cardiovasc Interv, February 26, 2018, vol. 11(4), pp. 384-392. \167\ Dwyer, M., et al., ``Pre-procedural white matter lesion burden predicts MRI outcomes in transcatheter aortic valve replacement (TAVR): The SENTINEL Trial.'' --------------------------------------------------------------------------- In retrospect, the SENTINEL[supreg] trial was underpowered for the surrogate efficacy endpoint. However, according to the applicant, a meta-analysis of all three randomized trials of Claret dual-filter technology in TAVR using MRI endpoints by Latib, et al. (2017), which had an increased number of patients available for analysis, did show statistically significant reduction in new lesion volume. The primary safety endpoint for the SENTINEL[supreg] trial was occurrence of all Major Adverse Cardiac and Cerebrovascular Events (MACCE) at 30 days compared to a historical performance goal, and the Sentinel[supreg] Cerebral Protection System met this endpoint for noninferiority (p<0.001) and superiority (p=0.0026) The SENTINEL[supreg] trial was not designed to be powered to show a statistically significant reduction in procedural stroke between trial arms at 30-days; therefore, it did not reach statistical significance. However, according to the applicant, investigators were encouraged by the trend to lower rates of stroke in the Sentinel[supreg] arms (5.6 percent) as compared to Control (9.1 percent) at 30-days. Additionally, more than 60 percent of ischemic neurological events in TAVR occur during the acute peri procedural phase as a result of thromboembolic debris released from manipulation of TAVR and accessory devices in a heavily atherosclerotic vascular and valvular structures.\168\ As a result, the SENTINEL[supreg] investigators and FDA Advisory Panel at large were, according to the applicant, keen to temporally analyze the stroke data in two phases (acute and subacute). The applicant stated that this post-hoc analysis demonstrated that the acute phase is the critical period where cerebral protection offers the most protection against any incidence of stroke by demonstrating a significant treatment effect of 63 percent at <72 hours. This window was less confounded by events that may occur later in the subacute phase after a TAVR procedure as a result of new onset AF or suboptimal anticoagulation/antiplatelet regimens. --------------------------------------------------------------------------- \168\ Kapadia, S., et al., Circ Cardiovasc Interv, September 2016, vol. 9(9), pp. 1-10. --------------------------------------------------------------------------- Response: We appreciate the applicant's input and have considered this information in our determination below. Comment: With regard to CMS' concern in the proposed rule that the use of cerebral protection devices may not be associated with a significant reduction in stroke and death (as noted previously, we have corrected our statement from the proposed rule on the findings of the meta-analysis on which this statement was based), the applicant stated that the meta-analysis of 180 randomized patients from 3 small randomized trials from 2016 did not include the results from the SENTINEL[supreg] randomized trial, which were not available at the time, but the authors of this study (Giustino, G., et al.\169\) subsequently published in 2017 an updated systematic review and meta- analysis of 5 randomized trials totaling 625 patients (in which the SENTINEL[supreg] trial contributed 363 patients to the 625 [[Page 41347]] patients in the 2017 meta-analysis). The 2017 Guistino, G., et al. meta-analysis evaluated EP during TAVR, including SENTINEL[supreg], and showed that at 30 days EP was associated with a lower risk of death or stroke on relative (6.4 percent versus 10.8 percent; RR: 0.57; 95 percent CI: 0.33 to 0.98; p=0.04; I2=0 percent) and absolute (ARD: -4.4 percent; 95 percent CI: -9.0 percent to -0.1 percent; NNT=22) terms (that is, for every 22 patients assigned to an EP device, 1 death or stroke event may be averted). According to the applicant, these findings suggest that EP may be a clinically relevant adjunctive strategy in patients undergoing TAVR procedures. The applicant noted that in the updated analysis, the authors of Giustino, G., et al. stated that, in conclusion, the totality of the data suggests that use of EP during TAVR appears to be associated with a significant reduction in death or stroke. --------------------------------------------------------------------------- \169\ Giustino, G., Sabato, S., Mehran, R., Faggioni, M., and Dangas, G., ``Cerebral Embolic Protection During TAVR, A Clinical Event Meta-Analysis,'' JACC, 2017, vol. 69, pp. 465-66. --------------------------------------------------------------------------- The applicant stated that an independent group recently published a similar meta-analysis of the same 5 randomized trials in the Journal of Thoracic Disease \170\ and reached the same conclusion as Giustino, G., et al. The applicant indicated that a third meta-analysis has been accepted that is in press, which includes 5 randomized and prospective observational studies, totaling 1,160 TAVR patients, in which cerebral embolic protection was used in 661.\171\ According to the applicant, the authors found that the risk of strokes within the first week of TAVR was significantly lower in the CPD group [0.56(95 percent CI 0.33- 0.96)]; p=0.034. The authors concluded that TAVR with CPD is associated with decreased strokes within 1 week of follow-up and not associated with an increase in peri-procedural adverse events. The applicant stated that it is important to note that the effectiveness of cerebral protection devices is during the procedure and best measured within a week or less of the procedure. The applicant further noted that events occurring after 1 week, up to and beyond 30 days are often associated with new-onset atrial fibrillation associated with the valve implant, inadequate anticoagulation regimen, and unrelated background risk. --------------------------------------------------------------------------- \170\ Wang N and Phan K, ``Cerebral protection devices in transcatheter aortic valve replacement: a clinical meta-analysis of randomized controlled trials'', J Thorac Dis, 2018;10(3):1927-1935. \171\ Mohananey D, et al. ``Safety and Efficacy of Cerebral Protection Devices in Transcatheter Aortic Valve Replacement: A Clinical End-points Meta-analysis.'' Cardiovasc Revasc Med, 2018 Feb 16. --------------------------------------------------------------------------- Response: In the comment above, the applicant focused on the 2017 meta-analysis from Giustino, G., et al.\172\ and stated, as indicated in the summary above, that the authors concluded that the totality of the data suggests that use of EP during TAVR appears to be associated with a significant reduction in death or stroke. --------------------------------------------------------------------------- \172\ Giustino, G., Sabato, S., Mehran, R., Faggioni, M., and Dangas, G., ``Cerebral Embolic Protection During TAVR, A Clinical Event Meta-Analysis,'' JACC, 2017, vol. 69, pp. 465-66. --------------------------------------------------------------------------- However, in April 2018, based on updated data, the authors for the 2017 Giustino, G., et al. publication updated their conclusion of the 2017 meta-analysis and stated the following: ``In conclusion, the totality of the data suggests that use of EP during TAVR appears to be associated with a nonsignificant trend towards reduction in death or stroke.'' Therefore, we continue to be concerned that the use of cerebral protection devices may not be associated with a significant reduction in stroke and death beyond 7 days (which is the focus of the meta-analysis). However, we note, as discussed below, the applicant has responded with additional information regarding the reduction in death or stroke within 7 days. Comment: In response to CMS' concerns as indicated in the proposed rule that the studies involving the Sentinel[supreg] Cerebral Protection System may be inconclusive regarding whether the device represented a substantial clinical improvement for patients undergoing TAVR procedures, the applicant referenced the academic study from the University of Ulm in Germany, which was independently funded and conducted, and published by Seeger, J., et al.\173\ The applicant stated that this study is an example of performance in routine clinical use, as investigators used the Sentinel[supreg] Cerebral Protection System in 280 consecutive TAVR patients and compared results in a propensity-score analysis to recent unprotected patients from the same institution, with the same operators, and the same independent neurologist who adjudicated all the neurological events. According to the applicant, this approach gives information about performance in a broad set of patients seen in clinical practice, unrestricted by inclusion and exclusion criteria of randomized trials. The applicant further explained that the academic study from the University of Ulm used propensity-score analysis based on an optimal matching attempt by adjusting/matching up to 14 key confounders after performing a comprehensive multivariable analysis by stepwise forward regression to evaluate independent predictors of clinical events. The applicant explained that propensity-score analyses are well accepted in the interventional cardiology and medical device community at large. The applicant further stated that propensity-score analyses are an alternative when randomized trials are not possible, practical, or ethical. For example, according to the applicant, in the case of cerebral embolic protection, investigators have struggled with ethical and moral imperatives of randomizing when many patients do not want to enter a randomized trial when they know that the device is already commercially available. --------------------------------------------------------------------------- \173\ Seeger, J., et al., ``Cerebral Embolic Protection During Transfemoral Aortic Valve Replacement Significantly Reduces Death and Stroke Compared With Unprotected Procedures,'' JACC Cardiovasc Interv, 2017. --------------------------------------------------------------------------- The applicant added that it believed that the 1 to 7 day time period is the most appropriate for evaluation of cerebral protection efficacy because it is difficult to accurately diagnose neurological impairment immediately post-operatively when the patient is recovering from the effects of anesthesia and some sequelae of embolic events can take time to evolve and be diagnosed, and conversely time points later than a week or so are confounded by strokes unrelated to embolic events during the index procedure, such as New Onset of Atrial Fibrillation (NOAF), suboptimal concomitant anti-platelet/anticoagulation medication, and other comorbid history of the patients. The applicant noted that, in the past few months, a number of TAVR centers have begun to share their data from routine practice using the Sentinel[supreg] Cerebral Protection System in TAVR procedures, which are in line with the clinical event reductions seen in the aforementioned trials. The applicant provided information from the following TAVR centers: Erasmus Medical Center (Rotterdam, The Netherlands) demonstrated comprehensive and systematic analysis of 747 TAVR patients treated with or without the use of the Sentinel[supreg] EP with independent neurological adjudication of the events. The applicant noted that, as presented by Nicolas van Mieghem, MD at the Joint Interventional Meeting (JIM) 2018 and Cardiovascular Research Technologies (CRT) 2018 conferences in February and March, there was an 80 percent relative risk reduction from 5 percent (23/453) to 1 percent (3/294) for all-stroke + TIA at 3 days with use of Sentinel[supreg] (p<0.01). Data from Cedars-Sinai Medical Center in Los Angeles, CA from a [[Page 41348]] comprehensive and systematic analysis of 419 TAVR patients treated with or without the use of the Sentinel[supreg] EP results show: 78 percent relative risk reduction from 6.3 percent (8/128) to 1.4 percent (4/291) for all-stroke at 7 days with use of Sentinel[supreg] (HR 0.22 (95 percent CI: 0.06 to 0.74, p=0.01). Data from Pinnacle Health (Harrisburg, PA) as presented by Hemal Gada, MD at the CMS New Technology Town Hall meeting, February 2018, demonstrated a reduction from 10 percent (7/69) 7-day stroke rate without the use of the Sentinel[supreg] to 0 percent (0/53) with the use of the Sentinel[supreg], as of the time at the Town Hall presentation in February. The applicant concluded that the clinical evidence is robust, consistent, reliable, and repeatable and that the totality of the data shows that Sentinel[supreg] Cerebral Protection System represents a substantial clinical improvement for patients undergoing TAVR procedures. Response: We appreciate the applicant's response to our concerns and its additional input. We agree with the applicant that the 1 to 7 day time period is the most appropriate for evaluation of cerebral protection efficacy. Specifically, as the commenter noted, it is difficult to accurately diagnose neurological impairment immediately post-operatively when the patient is recovering from the effects of anesthesia and some sequelae of embolic events can take time to evolve and be diagnosed. Conversely, time points later than 7 days are confounded by strokes unrelated to embolic events during the index procedure, such as NOAF, suboptimal concomitant anti-platelet/ anticoagulation medication, and other comorbid history of the patients. We believe that the use of propensity matching in the Ulm study supports the statistical difference of all-cause mortality or stroke at 7 days. Specifically, as stated above, in the Ulm study, the primary outcome was a composite of all-cause mortality or stroke at 7 days, and occurred in 2.1 percent of the Sentinel[supreg] Cerebral Protection System group versus 6.8 percent of the control group (p=0.01, number needed to treat (NNT)=21). Use of the Sentinel[supreg] Cerebral Protection System device was associated with a 2.2 percent absolute risk reduction in mortality with NNT=45. Composite endpoint of major adverse cardiac and cerebrovascular events (MACCE) was found in 2.1 percent of those patients undergoing a TAVR procedure with the use of the Sentinel[supreg] Cerebral Protection System device versus 7.9 percent in the control group (p=0.01). Therefore, we believe the data provided by the applicant showing reduced mortality and stroke within 7 days of a TAVR procedure as compared to patients undergoing a TAVR procedure without a cerebral protection device demonstrate that the Sentinel[supreg] Cerebral Protection System represents a substantial clinical improvement. After consideration of the public comments we received, we have determined that the Sentinel[supreg] Cerebral Protection System meets all of the criteria for approval for new technology add-on payments. Therefore, we are approving new technology add-on payments for the Sentinel[supreg] Cerebral Protection System for FY 2019. Cases involving the use of the Sentinel[supreg] Cerebral Protection System that are eligible for new technology add-on payments will be identified by ICD-10-PCS procedure code X2A5312. In its application, the applicant estimated that the cost of the Sentinel[supreg] Cerebral Protection System is $2,400. Under Sec. 412.88(a)(2), we limit new technology add-on payments to the lesser of 50 percent of the average cost of the technology, or 50 percent of the costs in excess of the MS-DRG payment for the case. As a result, the maximum new technology add-on payment for a case involving the use of the Sentinel[supreg] Cerebral Protection System is $1,400 for FY 2019. i. The AquaBeam System (Aquablation) PROCEPT BioRobotics Corporation submitted an application for new technology add-on payments for the AquaBeam System (Aquablation) for FY 2019. According to the applicant, the AquaBeam System is indicated for the use in the treatment of patients experiencing lower urinary tract symptoms caused by a diagnosis of benign prostatic hyperplasia (BPH). The AquaBeam System consists of three main components: a console with two high-pressure pumps, a conformal surgical planning unit with trans- rectal ultrasound imaging, and a single-use robotic hand-piece. The applicant reported that The AquaBeam System provides the operating surgeon a multi-dimensional view, using both ultrasound image guidance and endoscopic visualization, to clearly identify the prostatic adenoma and plan the surgical resection area. Based on the planning inputs from the surgeon, the system's robot delivers Aquablation, an autonomous waterjet ablation therapy that enables targeted, controlled, heat-free and immediate removal of prostate tissue used for the purpose of treating lower urinary tract symptoms caused by a diagnosis of BPH. The combination of surgical mapping and robotically-controlled resection of the prostate is designed to offer predictable and reproducible outcomes, independent of prostate size, prostate shape or surgeon experience. In its application, the applicant indicated that benign prostatic hyperplasia (BPH) is one of the most commonly diagnosed conditions of the male genitourinary tract \174\ and is defined as the ``. . . enlargement of the prostate due to benign growth of glandular tissue . . .'' in older men.\175\ BPH is estimated to affect 30 percent of males that are older than 50 years old.\176\ \177\ BPH may compress the urethral canal possibly obstructing the urethra, which may cause symptoms that effect the lower urinary tract, such as difficulty urinating (dysuria), hesitancy, and frequent urination.\178\ \179\ \180\ --------------------------------------------------------------------------- \174\ Bachmann, A., Tubaro, A., Barber, N., d'Ancona, F., Muir, G., Witzsch, U., Thomas, J., ``180-W XPS GreenLight Laser Vaporisation Versus Transurethral Resection of the Prostate for the Treatment of Benign Prostatic Obstruction: 6-month safety and efficacy results of a european multicentre randomised trial--the GOLIATH study,'' European Association of Urology, 2014, vol. 65, pp. 931-942. \175\ Gilling, P., Anderson, P., and Tan, A., ``Aquablation of the Prostate for Symptomatic Benign Prostatic Hyperplasia: 1-Year results,'' The Journal of Urology, 2017, vol. 197, pp. 156-1572. \176\ Roehrborn, C., Gange, S., Shore, N., Giddens, J., Bolton, D., Cowan, B., Rukstalist, D., ``The Prostatic Urethral Lift for the Treatmentof Lower Urinary Tract Symptoms Associated with Prostate Enlargement Due to Benign Prostatic Hyperplasia: The LIFT study,'' The Journal of Urology, 2013, vol. 190, pp. 2161-2167. \177\ Sonksen, J., Barber, N., Speakman, M., Berges, R., Wetterauer, U., Greene, D., Gratzke, C., ``Prospective, Randomized, Multinational Study of Prostatic Urethral Lift Versus Transurethral Resection of the Prostate: 12-month results from the BPH6 study,'' European Association of Urology, 2015, vol. 68, pp. 643-652. \178\ Roehrborn, C., Gange, S., Shore, N., Giddens, J., Bolton, D., Cowan, B., Rukstalist, D., ``The Prostatic Urethral Lift for the Treatmentof Lower Urinary Tract Symptoms Associated with Prostate Enlargement Due to Benign Prostatic Hyperplasia: The LIFT study,'' The Journal of Urology, 2013, vol. 190, pp. 2161-2167. \179\ Sonksen, J., Barber, N., Speakman, M., Berges, R., Wetterauer, U., Greene, D., Gratzke, C., ``Prospective, Randomized, Multinational Study of Prostatic Urethral Lift Versus Transurethral Resection of the Prostate: 12-month results from the BPH6 study,'' European Association of Urology, 2015, vol. 68, pp. 643-652. \180\ Roehrborn, C., Gilling, P., Cher, D., and Templin, B., ``The WATER Study (Waterjet Ablation Therapy for Ednoscopic Resection of prostate tissue),'' Redwood City: PROCEPT BioRobotics Corporation, 2017. --------------------------------------------------------------------------- The initial treatment for a patient who has been diagnosed with BPH is watchful waiting and medications.\181\ Symptom severity, as measured by one test, the International Prostate Symptom Score (IPSS), is the primary measure by which surgery necessity is decided.\182\ [[Page 41349]] Many techniques exist for the surgical treatment of patients who have been diagnosed with BPH, and these surgical treatments differ primarily by the method of resection: electrocautery in the case of Transurethral Resection of the Prostate (TURP), laser enucleation, plasma vaporization, photoselective vaporization, radiofrequency ablation, microwave thermotherapy, and transurethral incision \183\ are among the primary methods.

The applicant further stated that the AquaBeam System yields consistent and predictable procedure and resection times regardless of the size and shape of the prostate and the surgeon's experience. Lastly, according to the applicant, the AquaBeam System provides increased efficacy and safety for larger prostates as compared to the TURP procedure. With respect to the newness criterion, FDA granted the applicant's De Novo request on December 21, 2017, for use in the resection and removal of prostate tissue in males suffering from lower urinary tract symptoms (LUTS) due to benign prostatic hyperplasia. The applicant stated that the AquaBeam System was made available on the U.S. market immediately after the FDA granted the De Novo request. Therefore, we stated in the proposed rule that if approved for new technology add-on payments, the newness period is considered to begin on December 21, 2017. CMS has approved the use of ICD-10-PCS code XV508A4 (Destruction of prostate using robotic waterjet ablation, via natural or artificial opening endoscopic, new technology group 4), effective October 1, 2018, to uniquely identify procedures involving the AquaBeam System. As discussed earlier, if a technology meets all three of the substantial similarity criteria, it would be considered substantially similar to an existing technology and would not be considered ``new'' for the purposes of new technology add-on payments. With regard to the first criterion, whether a product uses the same or a similar mechanism of action to achieve a therapeutic outcome, the applicant stated that the AquaBeam System is the first technology to deliver treatment to patients who have been diagnosed with BPH for the symptoms that effect the lower urinary tract caused by BPH via Aquablation therapy. The AquaBeam System utilizes intra-operative image guidance for surgical planning and then Aquablation therapy to robotically resect tissue utilizing a high-velocity waterjet. According to the applicant, all other BPH treatment procedures only utilize cystoscopic visualization, whereas the AquaBeam System utilizes Aquablation therapy, a combination of cystoscopic visualization and intra-operative image guidance. According to the applicant, the AquaBeam System's use of Aquablation therapy qualifies it as the only technology to utilize a high-velocity room temperature waterjet for tissue resection, while most other BPH surgical procedures utilize thermal energy to resect prostatic tissue, or require the implantation of clips to pull back prostatic tissue blocking the urethra. Lastly, according to the applicant, all other surgical modalities are executed by the operating surgeon, while the AquaBeam System allows planning by the surgeon and utilization of Aquablation therapy ensures accurate and efficient tissue resection is autonomously executed by the robot. With respect to the second criterion, whether a product is assigned to the same or a different MS-DRG, the applicant stated that potential cases representing potential patients who may be eligible for treatment involving the AquaBeam System's Aquablation therapy technique will ultimately map to the same MS-DRGs as cases for existing BPH treatment options. With respect to the third criterion, whether the new use of the technology involves the treatment of the same or similar type of disease and the same or similar patient population, the applicant [[Page 41350]] stated that the AquaBeam System's Aquablation therapy will ultimately treat the same patient population as other available BPH treatment options. The applicant asserted that the AquaBeam System's Aquablation therapy has been shown to be more effective and safer than the TURP procedure for patients with larger prostate sizes. The applicant stated that prostates 80 ml or greater in size are not appropriate for the TURP procedure and, therefore, more intensive procedures such as surgery are required. Furthermore, the applicant claimed that the AquaBeam System's Aquablation therapy is particularly appropriate for smaller prostate sizes, ~30 ml, due to increased accuracy provided by both the computer assistance and ultrasound visualization. In the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20346), we stated we had the following concerns regarding whether the AQUABEAM System meets the newness criterion. Currently, there are many treatment options that utilize varying forms of ablation, such as mono and bipolar TURP procedures, laser, microwave, and radiofrequency, to treat the symptoms associated with a diagnosis of BPH. We stated that we were concerned that, while this device utilizes water to perform any tissue removal, its mechanism of action may not be different from that of other forms of treatment for patients who have been diagnosed with BPH. Further, the use of water to perform tissue removal in the treatment of associated symptoms in patients who have been diagnosed with BPH has existed in other areas of surgical treatment prior to the introduction of this product (for example, endometrial ablation and wound debridement). In addition, the standard operative treatment, such as with the TURP procedure, for patients who have been diagnosed with BPH is to widen the urethra compressed by an enlarged prostate in an effort to alleviate the negative effects of an enlarged prostate. Like other existing methods, the AQUABEAM System's Aquablation therapy also ablates tissue to relieve compression of the urethra. Additionally, while the robotic arm and computer programing may result in different outcomes for patients, we stated we were uncertain that the use of the robotic hand and computer programming result in a new mechanism of action. We invited public comments on this issue. We also invited public comments on whether the AQUABEAM System's Aquablation therapy is substantially similar to existing technologies and whether it meets the newness criterion. Comment: The applicant stated in regard to the beginning of the newness period that, while the AQUABEAM System received approval from the FDA for its De Novo request on December 21, 2017, local non- coverage determinations in the Medicare population resulted in the first case being delayed until April 19, 2018. Therefore, the applicant believed that the beginning date of the newness period should begin on April 9, 2018, instead of the date FDA granted the De Novo request. Response: With regard to the beginning of the technology's newness period, as discussed in the FY 2005 IPPS final rule (69 FR 49003), the timeframe that a new technology can be eligible to receive new technology add-on payments begins when data begin to become available. While local non-coverage determinations may limit the use of a technology in different regions in the country, a technology may be available in regions where no local non-coverage decision existed (with data beginning to become available). Additionally, similar to the discussion in the FY 2006 IPPS final rule (70 FR 47349), we do not consider how frequently the medical service or technology has been used in the Medicare population in our determination of newness. We welcome further information from the applicant for consideration in future rulemaking regarding the beginning of the newness period. Comment: The applicant reiterated in response to CMS' concerns regarding the mechanism of action of the AquaBeam System that it is novel because of: (1) The real-time multi-dimensional imaging which enables improved clinical decision-making and personalized treatment planning; (2) the accuracy of the autonomous robotic hand piece which autonomously executes the surgeon's treatment plan for controlled and precise tissue removal; and (3) the heat free submerged waterjet used to resect prostatic tissue which avoids the possibility of complications arising from thermal injury, and that these qualities result in consistently safe and effective outcomes for patients and greatly reduced chances of side effects when compared to TURP and further provide a minimally invasive transurethral alternative to open prostatectomy (OP) in large prostates. The applicant further indicated that each of the three components, individually, are unique to existing BPH surgical options and the combination of the three further represents the novelty of the technology's mechanism of action in the treatment of BPH. The applicant also believed that CMS' concerns that the use of water to perform tissue removal may not be different than other forms of tissue removal in treating BPH, the use of water has been used in other areas such as endometrial ablation and wound debridement, and there is uncertainty that the use of a robotic hand and computer programming result in a new mechanism of action reflect a broad interpretation of mechanism of action. The applicant stated that the notion that all ablation techniques are similar ignores the fact that ablation is used to treat a variety of illnesses and conditions throughout the body using a variety of technological approaches with varying effectiveness. The applicant reiterated that it believed the three mechanisms of action of the AquaBeam System are unique in prostate treatment when compared to all other existing prostate treatments, and the AquaBeam System is the only ablation technique that utilizes room-temperature water whereas other ablative approaches such as TURP, laser vaporization (PVP), laser resection (HoLEP/ThuLEP), microwave necrosis (TUMT), and mechanical radio-frequency resection (open simple prostatectomy) utilize heat as the primary mechanism of action. The applicant explained that the waterjet mechanism of action has the advantage of sparing sensitive tissues around the prostate like the bladder neck, verumontanum, and nerve and vascular tissues, whereas other ablative approaches are tissue agnostic. The applicant also disagreed with CMS' comparison of Aquablation therapy to wound debridement and tissue dissection because the surgical goals are different. The applicant stated that, in the application of wound debridement the surgical goal is wound cleansing and debris removal using a waterjet, and in tissue dissection, the goal is tissue separation or disassociating the parenchymal connective tissue. The applicant further stated, in contrast, the goal of all BPH surgical procedures is to remove excessive prostatic tissue. The applicant reiterated that the use of the robotic handpiece and computer programming is the essence of the AquaBeam System to deliver Aquablation therapy, and these components allow the surgeon to visualize the prostate in a way that was previously unavailable in BPH surgery to precisely determine the specific prostatic tissue to resect, which is not possible with existing technologies. The applicant further indicated that the [[Page 41351]] robotic handpiece autonomously executes the tissue resection, which has been clinically shown to provide consistent results, regardless of the prostate size or surgeon experience. The applicant believed that this differs from other treatment modalities, which rely on surgeon experience that introduces more variability into the procedure. The applicant stated that the robotic handpiece also facilitates the use of a minimally invasive transurethral approach to treat large prostates in which the vast majority of other transurethral technologies are not recommended. The applicant also stated that CMS has not historically applied such a broad definition when defining and evaluating mechanism of action, as in example, for new technology add-on payments for the INTUITY and Perceval valves that are aortic valve replacements that share the surgical goal of providing the patient with a functioning aortic valve. The applicant noted that, CMS determined the mechanisms of action of the INTUITY and Perceval valves in achieving the surgical goal were not substantially similar to treatments that were available at the time, and both technologies were approved for new technology add-on payments. In addition, the applicant stated that drug-coated balloons (a new combination of existing balloon and existing drugs) have a surgical goal similar to non-drug coated balloons of creating a lumen in the artery, and CMS determined that the drug-coated balloons used a different mechanism of action and similarly approved both applications for new technology add-on payments. The applicant explained that, in the case of Aquablation therapy, the surgical goal is similar to other BPH technologies in creating an opening in the prostatic urethra. However, the applicant indicated, as described above, the mechanism of action is different from any other technologies currently available. The applicant believed that, applying the same criterion as applied in the historical examples, the AquaBeam System meets the criteria for approval of new technology add-on payments. The applicant also stated that for large prostates, the MS-DRG assignment for potential cases representing patients eligible for treatment involving the AquaBeam System would be similar to normal transurethral prostate treatments, which is different than the MS-DRG assignment for open prostatectomy (OP). The applicant believed that potential cases involving Aquablation therapy would group to MS-DRGs 713 and 714 (Transurethral Prostatectomy) and open simple prostatectomy procedures would group to MS-DRGs 707 and 708 (Major Male Pelvic Procedures). The applicant stated that, for prostates sized less than 80 ml, potential cases involving Aquablation therapy would map to the same MS-DRGs as other transurethral procedures, and for large prostates greater than 80 ml in size, procedures involving Aquablation therapy in lieu of an open prostatectomy would result in a different MS-DRG assignment. Therefore, the applicant believed AquaBeam System's Aquablation therapy meets this criterion under substantial similarity. Other commenters believed that the AquaBeam System met the newness criterion. The commenters stated that the use of imaging and ultrasound, the autonomous robotic execution of the procedure, and the use of room temperature water rather than heat, combined make the AquaBeam System a novel treatment for BPH. Another commenter further indicated that many other technologies are surgeon- and experience- dependent, whereas the AquaBeam System's image guided procedure with robotic execution allows for a greater degree of precision and monitoring of the treatment independent of experience or expertise. The commenter believed that the addition of image guidance and robotic execution of the procedure leads to consistent results independent of surgeon experience. Response: We appreciate the commenters' input. After consideration of these comments, we agree that the AquaBeam System has a unique mechanism of action because it is the first to use waterjet ablation therapy that enables targeted, controlled, heat-free and immediate removal of prostate tissue used for the purpose of treating lower urinary tract symptoms caused by a diagnosis of BPH. Therefore, after consideration of the public comments we received, we agree that the AquaBeam System meets the newness criterion and the newness period beginning date is April 19, 2018. With regard to the cost criterion, the applicant conducted the following analysis to demonstrate that the technology meets the cost criterion. Given that at the time of the analysis, the AquaBeam System's Aquablation therapy procedure did not have a unique ICD-10-PCS procedure code, the applicant searched the FY 2016 MedPAR data file for cases with the following current ICD-10-PCS codes describing other BPH minimally invasive procedures to identify potential cases representing potential patients who may be eligible for treatment involving the AquaBeam System's Aquablation therapy: 0V507ZZ (Destruction of prostate, via natural or artificial opening), 0V508ZZ (Destruction of prostate, via natural or artificial opening endoscopic), 0VT07ZZ (Resection of prostate, via natural or artificial opening), and 0VT08ZZ (Resection of prostate, via natural or artificial opening endoscopic). The applicant identified a total of 133 MS-DRGs using these ICD-10-PCS codes. In order to calculate the standardized charges per case, the applicant conducted two analyses, based on 100 percent and 75 percent of identified claims in the FY 2016 MedPAR data file. The applicant based its analysis on 100 percent of claims mapping to 133 MS-DRGs, and 75 percent of claims mapping to 6 MS-DRGs. The cases identified in the 75 percent analysis mapped to MS-DRGs 665 (Prostatectomy with MCC), 666 (Prostatectomy with CC), 667 (Prostatectomy without CC/MCC), 713 (Transurethral Prostatectomy with CC/MCC), 714 (Transurethral Prostatectomy without CC/MCC), and 988 (Non-Extensive O.R. Procedures Unrelated to Principal Diagnosis with CC). In situations in which there were fewer than 11 cases for individual MS-DRGs in the MedPAR data file, a value of 11 was imputed to ensure confidentiality for patients. When evaluating 100 percent of the cases identified, the applicant included low-volume MS-DRGs that had equal to or less than 11 total cases to represent potential patients who may be eligible for treatment involving the AquaBeam System's Aquablation therapy in order to calculate the average case-weighted unstandardized and standardized charge amounts. The 75 percent analysis removed those MS-DRGs with 11 cases or less representing potential patients who may be eligible for treatment involving the AquaBeam System's Aquablation therapy, resulting in only 6 of the 133 MS-DRGs remaining for analysis. A total of 8,449 cases were included in the 100 percent analysis and 6,285 cases were included in the 75 percent analysis. Using the 100 percent and 75 percent samples, the applicant determined that the average case-weighted unstandardized charge per case was $69,662 and $47,475, respectively. The applicant removed 100 percent of total charges associated with the service category ``Medical/Surgical Supply Charge Amount'' (which includes revenue centers 027x and 062x) because the applicant believed that it was the most conservative choice, as this [[Page 41352]] amount varies by MS-DRG. The applicant stated that the financial impact of utilizing the AquaBeam System's Aquablation therapy on hospital resources other than on ``Medical Supplies'' is unknown at this time. Therefore, a value of $0 was used for charges related to the prior technology. The applicant standardized the charges, and inflated the charges using an inflation factor of 1.09357, from the FY 2018 IPPS/LTCH PPS final rule (82 FR 38524). The applicant then added the charges for the new technology. The applicant computed a final inflated average case- weighted standardized charge per case of $69,588 for the 100 percent sample, and $51,022 for the 75 percent sample. The average case- weighted threshold amount was $59,242 for the 100 percent sample, and $48,893 for the 75 percent sample. Because the final inflated average case-weighted standardized charge per case exceeded the average case- weighted threshold amount for both analyses, the applicant maintained that the technology met the cost criterion. We invited public comment regarding whether the technology meets the cost criterion. Comment: The applicant reiterated the results of the cost analysis detailed in the FY 2019 IPPS/LTCH PPS proposed rule, and believed that the AquaBeam System meets the cost criterion. Response: We appreciate the applicant's input and agree that the AquaBeam System meets the cost criterion. With respect to the substantial clinical improvement criterion, the applicant asserted that the Aquablation therapy provided by the AquaBeam System represents a substantial clinical improvement over existing treatment options for symptoms associated with the lower urinary tract for patients who have been diagnosed with BPH. Specifically, the applicant stated that the AquaBeam System's Aquablation therapy provides superior safety outcomes compared to the TURP procedure, while providing non-inferior efficacy in treating the symptoms that effect the lower urinary tract associated with a diagnosis of BPH; the AquaBeam System's delivery of Aquablation therapy yields consistent and predictable procedure and resection times regardless of the size and shape of the prostate or the surgeon's experience; and the AquaBeam System's Aquablation therapy demonstrated superior efficacy and safety for larger prostates (that is, prostates sized 50 to 80 ml) as compared to the TURP procedure. The applicant provided the results of one Phase I and one Phase II trial published articles, the WATER Study Clinical Study Report, and a meta-analysis of current treatments with its application as evidence for the substantial clinical improvement criterion. According to the applicant, the first study \195\ enrolled 15 nonrandomized patients with a prostate volume between 25 to 80 ml in a Phase I trial testing the safety and feasibility of the AquaBeam System's Aquablation therapy; all patients received the AquaBeam System's Aquablation therapy. This study, a prospective, nonrandomized study, enrolled men who were 50 to 80 years old who were affected by moderate to severe lower urinary tract symptoms, who did not respond to standard medical therapy.\196\ Follow-up assessments were conducted at 1, 3, and 6 months and included information on adverse events, serum PSA level, uroflowmetry, PVR, quality of life, and the International Prostate Symptom Score (IPSS) and International Index of Erectile Function (IIEF) scores. The primary outcome was the assessment of safety as measured by adverse event reporting; secondary endpoints focused on alleviation of BPH symptoms.\197\ --------------------------------------------------------------------------- \195\ Gilling, P., Reuther, R., Kahokehr, A., Fraundorfer, M., ``Aquablation--Image-guided Robot-assisted Waterjet Ablation of the Prostate: Initial clinical experience,'' British Journal of Urology International, 2016, vol. 117, pp. 923-929. \196\ Ibid. \197\ Ibid. --------------------------------------------------------------------------- The applicant indicated that 8 of the 15 patients who were enrolled in the trial had at least 1 procedure-related adverse event (for example, catheterization, hematuria, dysuria, pelvic pain, bladder spasms), which the authors reported to be consistent with outcomes from minimally-invasive transurethral procedures.\198\ There were no occurrences of incontinence, retrograde ejaculation, or erectile dysfunction at 30 days.\199\ Statistically significant improvement on all outcomes occurred over the 6-month period. Average IPSS scores showed a negative slope with scores of 23.1, 11.8, 9.1, and 8.6 for baseline, 1 month, 3 months, and 6 months (p<0.01 in all cases). Average quality of life scores, which range from 1 to 5, where 1 is better and 5 is worse, decreased from 5.0 at baseline to 2.6 at 1 month, 2.2 at 3 months, and 2.5 at 6 months. Average maximum urinary flow rate increased steadily across time points from 8.6 ml/s at baseline to 18.6 ml/s at 6 months. Lastly, average post-void residual urine volume decreased from 91 ml at baseline to 38 ml at 1 month, 60 ml at 3 months, and 30 ml at 6 months.\200\ --------------------------------------------------------------------------- \198\ Gilling, P., Anderson, P., and Tan, A., ``Aquablation of the Prostate for Symptomatic Benign Prostatic Hyperplasia: 1-Year results,'' The Journal of Urology, 2017, vol. 197, pp. 156-1572. \199\ Ibid. \200\ Gilling, P., Anderson, P., and Tan, A., ``Aquablation of the Prostate for Symptomatic Benign Prostatic Hyperplasia: 1-Year results,'' The Journal of Urology, 2017, vol. 197, pp. 156-1572. --------------------------------------------------------------------------- The second study \201\ presents results from a Phase II trial involving 21 men with a prostate volume between 30 to 102 ml who received treatment involving the AquaBeam System's Aquablation therapy with follow-up at 1 year. This prospective study enrolled men between the ages of 50 and 80 years old who were effected by moderate to severe symptomatic BPH.\202\ The primary end point was the rate of adverse events; the secondary end points measured alleviation of symptoms associated with a diagnosis of BPH. Data was collected at baseline and at 1 month, 3 months, 6 months, and 12 months; 1 patient withdrew at 3 months. The authors asserted that the occurrence of post-operative adverse events (urinary retention, dysuria, hematuria, urinary tract infection, bladder spasm, meatal stenosis) were consistent with other minimally-invasive transurethral procedures; \203\ 6 patients had at least 1 adverse event, including temporary urinary symptoms and medically-treated urinary tract infections.\204\ The mean IPSS scores decreased from the baseline of 22.8 with 11.5 at 1 month, 7 at 3 months, 7.1 at 6 months, and 6.8 at 12 months and were statistically significantly different. Similarly, quality of life decreased from a mean score of 5 at baseline to 1.7 at 12 months, all time points were statistically significantly different from the baseline. --------------------------------------------------------------------------- \201\ Ibid. \202\ Ibid. \203\ Ibid. \204\ Ibid. --------------------------------------------------------------------------- The third document provided by the applicant is the Clinical Study Report: WATER Study,\205\ a prospective multi-center, randomized, blinded study. The WATER Study compared the AquaBeam System's Aquablation therapy to the TURP procedure for the treatment of lower urinary tract symptoms associated with a diagnosis of BPH. One hundred eighty one (181) patients with prostate volumes between 30 and 80 ml were randomized, 65 patients to the TURP procedure group and the other 116 to [[Page 41353]] the AquaBeam System's Aquablation therapy group, with 176 (97 percent of patients) continuing at 3 and 6 month follow-up, where 2 missing patients received treatment involving the AquaBeam System's Aquablation therapy and 3 received treatment involving the TURP procedure; randomization efficacy was assessed and confirmed with findings of no statistical differences between cases and controls among all characteristics measures, specifically prostate volume. Two primary endpoints were identified: (1) The safety endpoint was the proportion of patients with adverse events rates as ``probably or definitely related to the study procedure'' also classified as the Clavien-Dindo (CD) Grade 2 or higher or any Grade 1 resulting in persistent disability; and (2) the primary efficacy endpoint was a change in the IPSS score from baseline to 6 months. Three secondary endpoints were based on perioperative data and were: length of hospital stay, length of operative time, and length of resection time. The occurrences of three secondary endpoints during the 6-month follow-up were: (1) Reoperation or reintervention within 6 months; (2) evaluation of proportion of sexually active patients; and (3) evaluation of proportion of patients with major adverse urologic events. --------------------------------------------------------------------------- \205\ Roehrborn, C., Gilling, P., Cher, D., Templin, B., ``The WATER Study (Waterjet Ablation Therapy for Ednoscopic Resection of prostate tissue),'' Redwood City: PROCEPT BioRobotics Corporation, 2017. --------------------------------------------------------------------------- At 3 months, 25 percent of the patients in the AquaBeam System's Aquablation therapy group and 40 percent of the patients in the TURP group had an adverse event. The difference of -15 percent has a 95 percent confidence interval of -29.2 and -1.0 percent. At 6 months, 25.9 percent of the patients in the AquaBeam System's Aquablation therapy group and 43.1 percent of the patients in the TURP group had an adverse event. The difference of -17 percent has a 95 percent confidence interval of -31.5 to -3.0 percent. An analysis of safety events classified with the CD system as possibly, probably or definitely related to the procedure resulted in a CD Grade 1 persistent event difference between -17.7 percent (favoring the AquaBeam System's Aquablation therapy) with 95 percent confidence interval of -30.1 to - 7.2 percent and a CD Grade 2 or higher event difference of -3.3 percent with 95 percent confidence interval of -16.5 to 8.7 percent. The applicant indicated that the primary efficacy endpoint was assessed by a change in IPSS score over time. While change in score and change in percentages are generally higher for the AquaBeam System's Aquablation therapy, no statistically significant differences occurred between the AquaBeam System's Aquablation therapy and the TURP procedure over time. For example, the AquaBeam System's Aquablation therapy group experienced changes in IPSS mean score by visit of 0, - 3.8, -12.5, -16.0, and -16.9 at baseline, 1 week, 1 month, 3 months, and 6 months, respectively, while the TURP group had mean scores of 0, -3.6, -11.1, -14.6, and -15.1 at baseline, 1 week, 1 month, 3 months, and 6 months, respectively. Lastly, the applicant indicated that secondary endpoints were assessed. A mean length of stay for both the AquaBeam System's Aquablation therapy and the TURP procedure groups of 1.4 was achieved. While the mean operative times were similar, the hand piece in and out time was statistically significantly shorter for the AquaBeam System's Aquablation therapy group at 23.3 minutes as compared to 34.2 in the TURP procedure group. The mean resection time was 23 minutes shorter for the AquaBeam System's Aquablation therapy group at 3.9 minutes. No statistically significant difference was seen between the AquaBeam System's Aquablation therapy and the TURP procedure groups on the outcomes of re-intervention and worsening sexual function; 32.9 percent of the AquaBeam System's Aquablation therapy group had worsening sexual function as compared to 52.8 percent of the TURP procedure group. While statistically significant differences occurred across groups for change in ejaculatory function, the difference no longer remained at 6 months. While a greater proportion of the TURP procedure group patients experienced a negative change in erectile function as compared to the AquaBeam System's Aquablation therapy group patients (10 percent versus 6.2 percent at 6 months), no statistically significant differences occurred. No statistically significant differences between groups occurred for major adverse urologic events. The applicant provided a meta-analysis of landmark studies regarding typical treatments for patients who have been diagnosed with BPH in order to provide supporting evidence for the assertion of superior outcomes achieved with the use of the AquaBeam System's Aquablation therapy. The applicant cited four ``landmark clinical trials,'' which report on the AquaBeam System's Aquablation therapy,\206\ the TURP procedure, Green light laser versus the TURP procedure,\207\ and Urolift.\208\ Comparisons are made between performance outcomes on three separate treatments for patients who have been diagnosed with BPH: the AquaBeam System's Aquablation therapy, the TURP procedure, and Urolift. The applicant stated that all three clinical trials included men with average IPSS baseline scores of 21 to 23 points. The applicant stated that, while total procedure times are similar across all three treatment options, the AquaBeam System's Aquablation therapy has dramatically less time and variability associated with the tissue treatment. The applicant further stated that the differences between treatment options were not assessed for statistical significance. The applicant indicated that the AquaBeam System's Aquablation therapy, with an approximate score of 17, had the largest improvement in IPSS scores at 6 months as compared to 16 for the TURP procedure and 11 for Urolift. Compared to 46 percent in the TURP group, the applicant found that the AquaBeam System's Aquablation therapy and Urolift had much lower percentages, 4 percent and 0 percent, respectively, of an ejaculation-related consequence in patients. Lastly, the applicant stated that safety events, as measured by the percentage of CD Grade 2 or higher events, were lower in the AquaBeam System's Aquablation therapy (19 percent) and Urolift (14 percent) than in TURP (29 percent). --------------------------------------------------------------------------- \206\ Roehrborn, C., Gilling, P., Cher, D., Templin, B., ``The WATER Study (Waterjet Ablation Therapy for Ednoscopic Resection of prostate tissue),'' Redwood City: PROCEPT BioRobotics Corporation, 2017. \207\ Bachmann, A., Tubaro, A., Barber, N., d'Ancona, F., Muir, G., Witzsch, U., Thomas, J., ``180-W XPS GreenLight Laser Vaporisation Versus Transurethral Resection of the Prostate for the Treatment of Benign Prostatic Obstruction: 6-month safety and efficacy results of a european multicentre randomised trial--the GOLIATH study,'' European Association of Urology, 2014, vol. 65, pp. 931-942. \208\ Sonksen, J., Barber, N., Speakman, M., Berges, R., Wetterauer, U., Greene, D., Gratzke, C., ``Prospective, Randomized, Multinational Study of Prostatic Urethral Lift Versus Transurethral Resection of the Prostate: 12-month results from the BPH6 study,'' European Association of Urology, 2015, vol. 68, pp. 643-652. --------------------------------------------------------------------------- In the FY 2019 IPPS/LTCH proposed rule (83 FR 20349), we stated that we have several concerns related to the substantial clinical improvement criterion. The applicant performed a meta-analysis comparing results from three separate studies, which tested the effects of three separate treatment options. According to the applicant, the results provided consistently show the AquaBeam System's Aquablation therapy and Urolift as being superior to the standard treatment of the TURP procedure. In the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20349), we stated we have concerns with the [[Page 41354]] interpretation of these results that the applicant provided. We noted that the comparison of multiple clinical studies is a difficult issue, and it was not clear if the applicant took into account the varying study designs, sample techniques, and other study specific issues, such as physician skill and patient health status. For instance, the applicant stated that a comparison of Urolift and the AquaBeam System's Aquablation therapy may not be appropriate due to the differing indications of the procedures; the applicant indicated that Urolift is primarily used for the treatment of patients who have been diagnosed with BPH who have smaller prostate volumes, whereas the AquaBeam System's Aquablation therapy procedure may be used in all prostate sizes. Similarly, the applicant stated that the TURP procedure is generally not utilized in patients with prostates larger than 80 ml, whereas such patients may be eligible for treatment involving the AquaBeam System's Aquablation therapy. We noted that the applicant submitted a meta-analysis in an effort to compare currently available therapies to the AquaBeam System's Aquablation therapy. We stated that the possibility of the heterogeneity of samples and methods across studies leads to the possible introduction of bias, which results in the difficulty or inability to distinguish between bias and actual outcomes. We invited public comments on the applicability of this meta-analysis. Comment: The applicant stated in response to CMS' concerns in regard to the meta-analysis that the meta-analysis was performed with the cited studies because of the similarities in geography where enrolled, inclusion of similar prostate size (30 to 80 ml), and the randomization against the same control of TURP. The applicant indicated that the objective of the analysis was to compare the reduced safety profile in ejaculatory dysfunction of Aquablation therapy compared to TURP as demonstrated in the WATER study, as well as to compare the safety profile of Aquablation therapy to the UroLift procedure. Response: We appreciate the applicant's response and have taken this new information into consideration in making a final determination, as indicated below. In the FY 2019 IPPS/LTCH PPS proposed rule (83 FR 20349), we indicated that we had a concern that the differences between the AquaBeam System's Aquablation therapy and standard treatment options may not be as impactful and confined to safety aspects. We stated that it appears that the data on efficacy supported the equivalence of the AquaBeam System's Aquablation therapy and the TURP procedure based upon noninferiority analysis. In the proposed rule, we stated we agree with the applicant that the safety data were reported as showing superiority of the AquaBeam System's Aquablation therapy over the TURP procedure, although the data were difficult to track because adverse consequences were combined into categories; the AquaBeam System's Aquablation therapy was reportedly better in terms of ejaculatory function. It was noted in the application that, while the AquaBeam System's Aquablation therapy was statistically superior to the TURP procedure in the CD Grade 1 + adverse events, it was not statistically different in the CD Grade 2 or greater category. The applicant stated that regardless of the method, the urethra is typically used as the means for performing the BPH treatment procedure, which necessarily increases the likelihood of CD Grade 2 adverse events in all transurethral procedures. In addition, the applicant noted that the treatment option may depend on the size of the prostate. The applicant stated that the AquaBeam System's Aquablation therapy is appropriate for small and large prostate sizes as a BPH treatment procedure. The AquaBeam System's Aquablation therapy has been shown to have limited positive outcomes as compared to the TURP procedure for prostates sized greater than 50 grams to 80 grams in each of the studies provided by the applicant. However, the applicant noted that the TURP procedure would not be used for prostates larger than 80 grams in size. Therefore, we stated in the proposed rule that we believe that another proper comparator for the AquaBeam System's Aquablation therapy may be laser or radical/open surgical procedures given their respective indication for small and large prostate sizes. Lastly, the applicant compared AquaBeam System's Aquablation therapy and the standard of care TURP procedure to support a finding of improved safety. We stated that there are other treatment modalities available that may have a similar safety profile as the AquaBeam System's Aquablation therapy and we are interested in information that compares the AquaBeam System's Aquablation therapy to other treatment modalities. We invited public comments on whether the AquaBeam System's Aquablation therapy meets the substantial clinical improvement criterion. Comment: In response to CMS' concerns from the proposed rule that, while the WATER safety data showed superiority, adverse consequences were difficult to track because the data were combined into a composite endpoint, the applicant explained that in the WATER study a CD1+ event was defined as involving persistent bladder spasms, bleeding, dysuria, pain, retrograde ejaculation, urethral damage, urinary retention, urinary tract infection, and urinary urgency/frequency/difficulty/ leakage. The applicant stated that data from the WATER study show Aquablation therapy was statistically superior to TURP in CD Grade 1+ adverse events. The applicant indicated that CD2 and above events are defined as those requiring pharmacological treatment, blood transfusions, endoscopic, surgical, or radiological interventions. The applicant stated that, after removal of the ejaculatory dysfunction events from the composite safety endpoint, the rate of CD2 and above adverse events for Aquablation therapy as compared to TURP was 19.8 percent and 23.1 percent, respectively. In response to CMS' concern with regard to the WATER study finding of Aquablation's improved safety relative to TURP and that other treatment modalities demonstrate safety profiles similar to Aquablation, the applicant stated that, while this may be true, treatment modalities such as TUIP, TUNA/RF, Microwave, and PUL have inferior efficacy to TURP in a variety of objective and subjective measures including peak urine flow, PVR reduction and BPH symptom reduction.\209\ However, the applicant indicated that, because the WATER study showed Aquablation efficacy similar to TURP for all prostate sizes and superiority in prostates sized 50 to 80 ml in volume, and that TURP shows superior efficacy to these other treatment modalities, Aquablation therapy offers an overall clinical improvement relative to these alternative treatment modalities. --------------------------------------------------------------------------- \209\ Christidis, D., McGrath, S., Perera, M., Manning, T., Bolton, D., & Lawrentschuk, N., ``Minimally invasive surgical therapies for benign prostatic hypertrophy: The rise in minimally invasive surgical therapies,'' Prostate International, 2017, pp. 41- 46. --------------------------------------------------------------------------- In response to CMS' concern that Aquablation has limited positive outcomes for prostates sized 50 to 80 ml, the applicant stated that in a pre-specified subgroup analysis the WATER study showed superior safety and efficacy in prostates sized 50 to 80 ml [[Page 41355]] compared to TURP. The applicant indicated that, in fact, because the subset analysis of men with prostates sized 50 to 80 ml in volume demonstrated Aquablation's superior outcomes over the TURP arm of the WATER study, the applicant sought to assess the efficacy and safety of the procedure in men with even larger prostates in the follow up WATER II study, which included prostates in sizes greater than 80 ml. In response to CMS' concern that Aquablation therapy performed on larger prostates should be compared with laser (that is, HoLEP) and open simple prostatectomy procedures, the applicant stated that between September and December 2017, 101 men (67 percent were Medicare eligible) with moderate-to-severe BPH symptoms and prostates sized 80 to 150 ml in volume underwent Aquablation therapy in the prospective multi-center international WATER II clinical trial. The applicant indicated that, as noted above, the American Urological Association (AUA) BPH surgical guidelines recommend open simple prostatectomy or laser enucleation for the treatment of large prostates (>80 ml in volume). The applicant explained that the primary purpose of the WATER II was to assess the safety profile for Aquablation therapy in larger prostates. The applicant stated that the overall CD Grades 2, 3, and 4 complications were recorded in 19 percent, 11 percent, and 5 percent, respectively.\210\ The applicant further stated that postoperative bleeding after Aquablation therapy that required transfusion (N=6, 5.9 percent) and/or cystoscopy with clot evacuation/fulguration (N=2, 2.0 percent) was observed in 8 patients during the procedural hospitalization.\211\ The applicant stated that these results compare favorably to simple prostatectomy because the severe hemorrhage rate (defined as patients with a diagnosis related to hemorrhage and those who underwent transfusion) has been reported as high as 29 percent (range 12 to 29 percent) based on a claims analysis of 35,171 patients \212\ who underwent the procedure. The applicant stated that Aquablation therapy has an average length of stay of 1.6 days compared to an average length of state of 5 days for prostatectomy. The applicant further indicated that transfusion rates for the AquaBeam System were less than those for the simple prostatectomy procedure. The applicant explained that the AquaBeam procedure is technically feasible even for surgeons with low or no prior experience, and open prostatectomy has higher morbidity rates, longer hospital stays, and longer catheter times than those for the AquaBeam System. --------------------------------------------------------------------------- \210\ Mihir, D., Bidar, M., Bhojani, N., Trainer, A., Arther, A., Kramolowsky, E., Doumanian, L., et al., ``WATER II (80-150 mL) Procedureal Outcomes,'' 2018, BJU International. \211\ Ibid. \212\ Pariser, J., Pearce, S., Patel, S., & Bales, G., ``National Trends of Simple Prostatectomy for Benign Prostatic Hyperplasia with and Analysis of Risk Factors for Adverse Perioperative Outcomes,'' 2015, Urology, vol. 86(4). --------------------------------------------------------------------------- In response to CMS' concern regarding the appropriateness of the AquaBeam System for prostates of smaller sizes (for example, <30 mls), the applicant apologized for any inference in its application regarding smaller prostate sizes because it was not its intention to make any specific claims regarding smaller prostates. Other commenters also believed that the AquaBeam System represented a substantial clinical improvement. Another commenter stated that all of its treated patients experienced improved urinary flow and decreased BPH symptoms following treatment with the AquaBeam System. The commenter further stated that treated patients appreciated the preservation of ejaculatory function and indicated they would undergo the procedure again. Two commenters summarized results from the WATER II study, a single-arm study of the AquaBeam System in patients diagnosed with BPH with >80 ml prostate volumes, and stated that the AquaBeam System decreases operative time, time under anesthesia, decreases the length of inpatient stays, and has fewer complications as compared to open prostatectomy, which is the standard treatment for large prostates greater than 80 ml in volume. Another commenter with an interest in providing the AquaBeam therapy at its facility stated that, if an adequate payment is provided for the therapy, increased volume will most likely reduce the cost of this method of treatment. Response: We appreciate the additional information provided by the applicant and the commenters' input. We agree that the results of the WATER study are statistically significant (95 percent confidence interval of the difference between AquaBeam and TURP) and superior to TURP in safety as evidenced by a lower proportion of persistent CD Grade 1 adverse events at 3 months (which measured in totality Bladder spasm, Bleeding, Dysuria, Pain, Retrograde ejaculation, Urethral damage, Urinary retention, Urinary tract infection, Urinary urgency/ frequency/difficulty/leakage). Additionally, patients enrolled in the WATER study with prostate sizes greater than 50 ml in volume and treated with Aquablation therapy had superior IPSS improvement than those treated with TURP, as well as better peak urinary flow rates (Qmax) at 6 months, and improved ejaculatory function and incontinence scores at 3 months. Results from the WATER II study for patients with large prostate volumes demonstrate better outcomes of the AquaBeam System over the standard-of-care, the open prostatectomy, regarding less operative time, decreased length of stay, and decreased rates of severe hemorrhage and transfusions. Based on the results above, we have determined the AquaBeam System represents a substantial clinical improvement for the resection and removal of prostate tissue in males suffering from lower urinary tract symptoms due to benign prostatic hyperplasia. After consideration of the public comments we received, we have determined that the AquaBeam System's Aquablation therapy meets all of the criteria for approval of new technology add-on payments. Therefore, we are approving new technology add-on payments for the AquaBeam System for FY 2019. Cases involving the AquaBeam System that are eligible for new technology add-on payments will be identified by ICD-10-PCS procedure code XV508A4 (Destruction of prostate using robotic waterjet ablation, via natural or artificial opening endoscopic, new technology group 4). In its application, the applicant estimated that the average Medicare beneficiary would require the transurethral procedure of one AQUABEAM System per patient. According to the application, the cost of the AQUABEAM System is $2,500 per procedure. Under Sec. 412.88(a)(2), we limit new technology add-on payments to the lesser of 50 percent of the average cost of the technology, or 50 percent of the costs in excess of the MS-DRG payment for the case. As a result, the maximum new technology add-on payment for a case involving the use of the AQUABEAM System's Aquablation System is $1,250 for FY 2019. In accordance with the current indication for the AQUABEAM System, CMS expects that the AQUABEAM System will be used in the treatment for adult patients experiencing lower urinary tract symptoms caused by a diagnosis of BPH. j. AndexXaTM (Andexanet alfa) Portola Pharmaceuticals, Inc. (Portola) submitted an application for new technology add-on payments for FY 2019 for the use of AndexXaTM (Andexanet alfa). (We note that the [[Page 41356]] applicant previously submitted applications for new technology add-on payments for FY 2017 and FY 2018 for Andexanet alfa, which were withdrawn). In the proposed rule, we discussed AndexXaTM as a reversal agent for patients treated with direct and indirect Factor Xa inhibitors when reversal of anticoagulation is needed due to life- threatening or uncontrolled bleeding. AndexXaTM received FDA approval on May 3, 2018, and is indicated for use in the treatment of patients treated with rivaroxaban and apixaban, when reversal of anticoagulation is needed due to life-threatening or uncontrolled bleeding. According to the FDA-approved prescribing information, AndexXaTM has not been shown to be effective for, and is not indicated for, the treatment of bleeding related to any Factor Xa inhibitors other than the direct Factor Xa inhibitors apixaban and rivaroxaban. Therefore, in this final rule, we discuss AndexXaTM in the context of the FDA-approved indication as a treatment of an anticoagulation reversal agent for rivaroxaban and apixaban only due to life-threatening or uncontrolled bleeding. AndexXaTM is an antidote used to treat patients who are receiving treatment with the Factor Xa inhibitors rivaroxaban and apixaban when reversal of anticoagulation is needed due to life- threatening or uncontrolled bleeding. Patients at high risk for thrombosis, including those who have been diagnosed with atrial fibrillation (AF) and venous thrombosis (VTE), typically receive treatment using long-term oral anticoagulation agents. Factor Xa inhibitors are oral anticoagulants used to prevent stroke and systemic embolism in patients who have been diagnosed with AF. These oral anticoagulants are also used to treat patients who have been diagnosed with deep-vein thrombosis (DVT) and its complications, pulmonary embolism (PE), and patients who have undergone knee, hip, or abdominal surgery. Rivarobaxan (Xarelto[supreg]), apixaban (Eliquis[supreg]), betrixaban (Bevyxxa[supreg]), and edoxaban (Savaysa[supreg]) are included in the new class of Factor Xa inhibitors, and are often referred to as ``novel oral anticoagulants'' (NOACs) or ``non-vitamin K antagonist oral anticoagulants.'' Although these anticoagulants have been commercially available since 2011, prior to May 3, 2018, there was no FDA-approved therapy used for the urgent reversal of Factor Xa inhibitors rivarobaxan and apixaban as a result of serious bleeding episodes. As stated above, AndexXaTM received FDA approval on May 3, 2018, and is indicated for use in the treatment of patients treated with rivaroxaban and apixaban, when reversal of anticoagulation is needed due to life-threatening or uncontrolled bleeding. The applicant received approval for two unique ICD-10-PCS procedure codes that became effective October 1, 2016 (FY 2017). The approved ICD-10-PCS procedure codes are: XW03372 (Introduction of Andexanet alfa, Factor Xa inhibitor reversal agent into peripheral vein, percutaneous approach, new technology group 2); and XW04372 (Introduction of Andexanet alfa, Factor Xa inhibitor reversal agent into central vein, percutaneous approach, new technology group 2). With regard to the ``newness'' criterion, as discussed earlier, if a technology meets all three of the substantial similarity criteria, it would be considered substantially similar to an existing technology and would not be considered ``new'' for purposes of new technology add-on payments. AndexXaTM is the first and the only antidote available to treat patients receiving apixaban and rivaroxaban who suffer a major bleeding episode and require urgent reversal of anticoagulation. Other anticoagulant reversal agents, such as KcentraTM and idarucizumab, do not reverse the effects of apixaban and rivaroxaban. Therefore, the applicant asserted that the technology is not substantially similar to any other currently approved and available treatment options for Medicare beneficiaries. We discussed the applicant's assertions in the context of the three substantial similarity criteria in the proposed rule, as also discussed below. With regard to the first criterion, whether a product uses the same or a similar mechanism of action to achieve a therapeutic outcome, the applicant indicated that AndexXaTM is the first anticoagulant reversal agent that binds to apixaban and rivaroxaban with high affinity, thereby sequestering the inhibitors and consequently rapidly reducing free plasma concentration of these Factor Xa inhibitors. The applicant asserted that this mechanism of action neutralizes the inhibitors' anticoagulant effect, which allows for the restoration of normal hemostasis. According to the applicant, AndexXaTM represents a significant therapeutic advance because it provides rapid reversal of the anticoagulation effect of apixaban and rivaroxaban in the event of a serious bleeding episode where other anticoagulant reversal agents, such as KcentraTM and idarucizumab, do not reverse the effects of these Factor Xa inhibitors. With regard to the second criterion, whether a product is assigned to the same or a different MS-DRG, the applicant stated that AndexXaTM is the first FDA-approved anticoagulant reversal agent for patients receiving rivaroxaban and apixaban, and the first reversal agent to be FDA-approved for these Factor Xa inhibitors. The applicant further stated that other anticoagulant reversal agents, such as KcentraTM and idarucizumab, do not reverse the effects of these Factor Xa inhibitors. Therefore, the MS-DRGs do not contain cases that represent patients who have been treated with any anticoagulant reversal agents for these Factor Xa inhibitors. With regard to the third criterion, whether the new use of the technology involves the treatment of the same or similar type of disease and the same or similar patient population, the applicant indicated that AndexXaTM is the only anticoagulant reversal agent available for treating patients who are receiving treatment with apixaban or rivaroxaban who experience serious, uncontrolled bleeding events or who require emergency surgery. Therefore, the applicant believed that AndexXaTM would be the first type of treatment option available to this patient population. As a result, we stated in the proposed rule that we believe that it appears that AndexXaTM is not substantially similar to any existing technologies. We invited public comments on whether AndexXaTM meets the substantial similarity criteria, and whether AndexXaTM meets the newness criterion. Comment: The applicant reiterated that AndexXaTM satisfies the newness criterion. With respect to mechanism of action, the applicant reiterated that AndexXaTM rapidly binds to apixaban and rivaroxaban with high affinity, acting as a decoy molecule that sequesters the inhibitors to rapidly reduce the free plasma concentrations and neutralize their antiacoagulant effects to allow restoration of normal hemostasis. With respect to treating the same or similar type of disease and the same or similar patient population, the applicant further indicated that, as the first and only FDA-approved antidote available for a patient population receiving treatment using apixaban or rivaroxaban who suffer a major bleeding episode and require urgent reversal of direct Factor Xa coagulation of these Factor Xa inhibitors, AndexXaTM is not substantially similar to any other currently approved and available treatment options for Medicare [[Page 41357]] beneficiaries. The applicant emphasized that, prior to the approval of AndexXaTM, the management of bleeding events in patients taking the Factor Xa inhibitors apixaban and rivaroxaban had been predicated on blood transfusions (that is, whole blood, packed red blood cells (RBCs), fresh frozen plasma (FFP), and/or platelets), or the use of a number of replacement clotting factor therapies (for example, fresh frozen plasma, Prothrombin Complex Concentrates (PCC), and recombinant activated Factor VIIa)--all of which are supportive measures that do not reverse the Factor Xa activity of these inhibitors. Finally, with respect to MS-DRG assignment, because AndexXaTM is the first and only FDA-approved reversal agent of Factor Xa inhibitor for the treatment of patients receiving apixaban and rivaroxaban who experience life-threatening or uncontrolled bleeding or require emergency surgery, and the first reversal agent to be approved for these Factor Xa inhibitors, the applicant believed that the MS-DRGs do not contain any cases that represent patients treated with AndexXaTM as a reversal agent for these Factor Xa inhibitors. Other commenters stated that AndexXaTM meets the newness criterion and is not substantially similar to any existing technologies because there is no other reversal agent available on the U.S. market for patients who are being treated with these Factor Xa inhibitors and experience severe bleeding. These commenters stated that other anticoagulant reversal agents do not reverse the effects of these Factor Xa inhibitors. Response: We appreciate the commenters' and the applicant's input on whether AndexXaTM meets the newness criterion. After review of the information provided by the applicant and consideration of the public comments we received, we believe that AndexXaTM meets the newness criterion and consider the beginning of the technology's newness period to be May 3, 2018, when the technology received FDA approval. With regard to the cost criterion, we stated in the proposed rule that the applicant researched the FY 2015 MedPAR claims data file for potential cases representing patients who may be eligible for treatment using AndexXaTM. The applicant used three sets of ICD-9-CM codes to identify these cases: (1) Codes identifying potential cases representing patients who were treated with an anticoagulant and, therefore, who are at risk of bleeding; (2) codes identifying potential cases representing patients with a history of conditions that were treated with Factor Xa inhibitors; and (3) codes identifying potential cases representing patients who experienced bleeding episodes as the reason for the current admission. The applicant included with its application the following table displaying a complete list of ICD-9-CM codes that met its selection criteria. ------------------------------------------------------------------------ ICD-9-CM codes applicable Applicable ICD-9-CM code description ------------------------------------------------------------------------ V12.50.................... Personal history of unspecified circulatory disease. V12.51.................... Personal history of venous thrombosis and embolism. V12.52.................... Personal history of thrombophlebitis.

The applicant also provided an analysis that was limited to cases representing 80 percent of all potential cases identified (41,255 cases) that mapped to the top 151 MS-DRGs. Under this analysis, the average case-weighted charge per case was $69,020. The applicant provided a third analysis that was limited to cases representing 25 percent of all potential cases identified (12,873 cases) that mapped to the top 9 MS-DRGs. This third analysis resulted in an average case-weighted charge per case of $46,974. Under each of these analyses, the applicant also provided sensitivity analyses based on variables representing two areas of uncertainty: (1) Whether to remove 40 percent or 60 percent of blood and blood administration charges; and (2) whether to remove pharmacy charges based on the ceiling price of factor eight inhibitor bypass activity (FEIBA), a branded anti-inhibitor coagulant complex, or on the pharmacy indicator 5 (PI5) in the MedPAR data file, which correlates to potential cases utilizing generic coagulation factors. Overall, the applicant conducted twelve sensitivity analyses, and provided the following rationales: The applicant chose to remove 40 percent and 60 percent of blood and blood administration charges because potential patients who may be eligible for treatment using AndexXaTM for Factor Xa reversal may still require blood and blood products to treat other conditions. Therefore, the applicant believed that it would be inappropriate to remove all of the charges associated with blood and blood administration because all of the charges cannot be attributed to Factor Xa reversal. The [[Page 41358]] applicant maintained that the amounts of blood and blood products required for treatment vary according to the severity of the bleeding. Therefore, the applicant stated that the use of AndexXaTM may replace 60 percent of blood and blood product administration charges for potential cases with less severity of bleeding, but only 40 percent of charges for potential cases with more severe bleeding. The applicant maintained that FEIBA is the highest priced clotting factor used for Factor Xa inhibitor reversal, and it is unlikely that pharmacy charges for Factor Xa reversal would exceed the FEIBA ceiling price of $2,642. Therefore, the applicant capped the charges to be removed at $2,642 to exclude charges unrelated to the reversal of Factor Xa anticoagulation. The applicant also considered an alternative scenario in which charges associated with pharmacy indicator 5 (PI5) were removed from the costs of potential cases that included this indicator in the MedPAR data. On average, charges removed from the costs of potential cases utilizing generic coagulation factors were much lower than the total pharmacy charges. The applicant noted that, in all 12 scenarios, the average case- weighted standardized charge per case for potential cases representing patients who may be eligible for treatment using AndexXa
