On February 20, 2025, the Drug Enforcement Administration (DEA or Government) issued an Order to Show Cause (OSC) to Hayriye Gok, M.D., of Philadelphia, Pennsylvania (Registrant). Request for Final Agency Action (RFAA), Exhibit (RFAAX) 1, at 1, 4. The OSC proposed the revocation of Registrant's Certificate of Registration (COR) No. FG3991115, alleging that Registrant is “currently without authority to . . . handle controlled substances in the Commonwealth of Pennsylvania, the state in which [she is] registered with DEA.” Id. at 2 (citing 21 U.S.C. 824(a)(3)).

The OSC notified Registrant of her right to file a written request for hearing, and that if she failed to file such a request, she would be deemed to have waived her right to a hearing and be in default. Id. at 2-3 (citing 21 CFR 1301.43). Here, Registrant did not request a hearing. RFAA, at 4.^[1] “A default, unless excused, shall be deemed to constitute a waiver of the registrant's/applicant's right to a hearing and an admission of the factual allegations of the [OSC].” 21 CFR 1301.43(e).

Further, “[i]n the event that a registrant . . . is deemed to be in default . . . DEA may then file a request for final agency action with the Administrator, along with a record to support its request. In such circumstances, the Administrator may enter a default final order pursuant to [21 CFR] 1316.67.” Id. at 1301.43(f)(1). Here, the Government has requested final agency action based on Registrant's default pursuant to 21 CFR 1301.43(c) and (f), 1301.46. RFAA, at 1; see also21 CFR 1316.67.

Findings of Fact

The Agency finds that, in light of Registrant's default, the factual allegations in the OSC are deemed admitted. According to the OSC, Registrant's Pennsylvania medical license was temporarily suspended by the Pennsylvania State Board of Medicine (Board) on November 21, 2024. RFAAX 1, at 2; see also RFAAX 3.^[2] According to Pennsylvania online records, of which the Agency takes ( printed page 30267) official notice,^[3] Registrant's Pennsylvania medical license has a status of “Suspension.” Pennsylvania BPOA License Search, https://www.pals.pa.gov/​#!/​page/​search (last visited date of signature of this Order). Accordingly, the Agency finds that Registrant is not licensed to practice medicine in Pennsylvania, the state in which she is registered with DEA.^[4]

Discussion

Pursuant to 21 U.S.C. 824(a)(3), the Attorney General may suspend or revoke a registration issued under 21 U.S.C. 823 “upon a finding that the registrant . . . has had [her] State license or registration suspended . . . [or] revoked . . . by competent State authority and is no longer authorized by State law to engage in the . . . dispensing of controlled substances.” With respect to a practitioner, DEA has also long held that the possession of authority to dispense controlled substances under the laws of the state in which a practitioner engages in professional practice is a fundamental condition for obtaining and maintaining a practitioner's registration. Gonzales v. Oregon, 546 U.S. 243, 270 (2006) (“The Attorney General can register a physician to dispense controlled substances `if the applicant is authorized to dispense . . . controlled substances under the laws of the State in which he practices.' . . . The very definition of a `practitioner' eligible to prescribe includes physicians `licensed, registered, or otherwise permitted, by the United States or the jurisdiction in which he practices' to dispense controlled substances. § 802(21)”). The Agency has applied these principles consistently. See, e.g., James L. Hooper, M.D.,76 FR 71371, 71372 (2011), pet. for rev. denied, 481 F. App'x 826 (4th Cir. 2012); Frederick Marsh Blanton, M.D.,43 FR 27616, 27617 (1978).^[5]

According to Pennsylvania statute, “dispense” means “to deliver a controlled substance, other drug or device to an ultimate user or research subject by or pursuant to the lawful order of a practitioner, including the prescribing, administering, packaging, labeling, or compounding necessary to prepare such item for that delivery.” 35 Pa. Stat. § 780-102(b) (West 2025). Further, a “practitioner” means “a physician . . . or other person licensed, registered or otherwise permitted to distribute, dispense, conduct research with respect to or to administer a controlled substance, other drug or device in the course of professional practice or research in the Commonwealth of Pennsylvania.” Id.

Here, the undisputed evidence in the record is that Registrant is not a currently licensed practitioner in Pennsylvania. As discussed above, a physician must be a licensed practitioner to dispense a controlled substance in Pennsylvania. Thus, because Registrant currently lacks authority to practice medicine in Pennsylvania and, therefore, is not currently authorized to handle controlled substances in Pennsylvania, Registrant is not eligible to maintain a DEA registration in Pennsylvania. Accordingly, the Agency will order that Registrant's DEA registration be revoked.
