Medical Waivers for Merchant Mariner Credential Applicants With the Following Conditions: Cardiomyopathy; Diabetes Mellitus; Narcolepsy; and Obstructive Sleep Apnea

The Coast Guard is seeking public comment on the policy clarification proposed in this document regarding the specific medical documentation the Coast Guard will consider in determining whether a medical waiver is warranted for merchant mariners with cardiomyopathy, diabetes mellitus, or obstructive sleep apnea. Additionally, the proposed policy clarification specifies that narcolepsy, idiopathic hypersomnia, and other hypersomnias of central origin, are medically disqualifying and generally not waiverable due to significant risk of sudden and unpredictable incapacitation of individuals who have these conditions.
