How do I get Medicare Part D to cover GLP-1 medications?

Medicare Part D typically requires prior authorization for GLP-1 medications like Ozempic, Wegovy, and Mounjaro. To get coverage, your doctor must submit documentation of medical necessity including your BMI, comorbidities (such as type 2 diabetes or cardiovascular disease), and evidence that other treatments have been tried. Medicare Part D covers GLP-1 medications for type 2 diabetes but historically excluded anti-obesity medications. The Inflation Reduction Act and recent CMS policy changes have expanded some coverage. Weight loss indication coverage began expanding in 2025-2026.

What should I do if my GLP-1 prior authorization is denied?

If your GLP-1 prior authorization is denied, request a copy of the denial letter with the specific reason for denial. Work with your doctor to prepare an appeal with additional clinical evidence of medical necessity. You can also request a peer-to-peer review between your doctor and the insurer's medical director. Use MedicalRecords.com's Undeniable tool to generate a professional appeal letter.

How long does it take to get prior authorization for GLP-1 medications?

Standard prior authorization decisions are required within 72 hours for urgent requests and within 3-14 days for non-urgent requests, depending on state law and your plan type. Expedited appeals (when delay would seriously jeopardize your health) must be decided within 72 hours. Denials can be appealed through internal and external review processes.
