Does Medicare cover weight loss medications?
It depends: standard Medicare Part D plans generally don't cover drugs used for weight loss, but a temporary Medicare GLP-1 Bridge program (starting July 1, 2026) covers certain GLP-1 weight-loss drugs at $50 a month for people who qualify — and the same drugs can be covered for another approved condition like type 2 diabetes.
What flips the answer
- Covered when
You qualify for the temporary Medicare GLP-1 Bridge program (Part D, 18+, meets the BMI/condition rules) — a covered GLP-1 (Wegovy, Zepbound KwikPen, or Foundayo) is $50 a month for weight loss with prior authorization.
- Covered when
The drug is prescribed for an approved non-weight-loss indication (type 2 diabetes, cardiovascular risk reduction, obstructive sleep apnea) and is on your Part D formulary.
- Not covered when
You don't qualify for the Bridge program, it's for weight loss alone, and your standard Part D plan doesn't list the drug — you'd pay cash or request a formulary exception.
Standard Medicare Part D drug plans have generally excluded drugs used for weight loss, so a prescription for Wegovy, Zepbound, or a similar medication written specifically to treat obesity historically wasn't a covered Part D benefit and you'd pay out of pocket.
As of July 1, 2026, that's no longer the whole story. The temporary, nationwide Medicare GLP-1 Bridge program covers certain GLP-1 drugs for weight loss — currently Wegovy, the Zepbound KwikPen, and Foundayo — at a $50 monthly copay for people with Part D who qualify. Eligibility is BMI-based: a BMI of 35+, or a BMI of 30–34.99 (or 27–29.99) with a qualifying condition like prediabetes, chronic kidney disease, or a prior heart attack or stroke. It requires prior authorization and a diet-and-exercise program.
There's also a separate path through the drug's other approved uses. Several of these drugs are FDA-approved for type 2 diabetes, cardiovascular risk reduction, or obstructive sleep apnea; when prescribed for one of those, your own Part D plan can cover them (and you generally wouldn't use the Bridge program).
Original Medicare (Parts A and B) generally doesn't cover self-administered prescription drugs, so any coverage comes through a Part D plan or the Bridge program. Not every weight-loss drug is covered, so check the specifics for your medication and plan.
