Medicare GLP-1 coverage: Bridge or regular Part D?

Short answer: the drug, formulation and reason for prescribing determine the coverage route. The temporary Bridge covers eligible weight-management prescriptions. Other covered indications belong with your Part D plan.

Cardiovascular history alone does not settle the route

A previous heart attack, stroke or symptomatic peripheral artery disease can be a Bridge qualifying condition with starting BMI 27 or higher. A prescription intended to reduce major cardiovascular-event risk follows Part D instead. Confirm the intended indication with your prescriber.

Check the exact formulation

CMS’s Bridge list includes Wegovy injections and tablets, Foundayo tablets and Zepbound KwikPen. Zepbound vials and single-dose pens are excluded. Other GLP-1 brand names are not substitutes for this list.
