Does Medicare cover weight loss medications?
It depends
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.
- 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 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.
What people typically pay
If you qualify for the GLP-1 Bridge program, a covered drug is a $50 copayment for a one-month supply. If the drug is covered under your own Part D plan for an approved condition like type 2 diabetes, you pay that plan's normal cost sharing, which varies widely by plan.
Without coverage, brand-name GLP-1 weight-loss drugs are expensive and often paid entirely out of pocket at cash retail price, though manufacturer savings programs and drug discount options can lower that. Actual cash prices vary widely.
Actual amounts vary by plan, drug, pharmacy, and any manufacturer discount, and the Bridge program's terms are temporary and may change.
How to actually get it covered
Confirm you have a Medicare Part D drug plan (through a standalone plan or a Medicare Advantage plan with drug coverage) — Original Medicare alone won't cover these self-administered drugs.
Ask your prescriber which route fits: the GLP-1 Bridge program for weight loss, or coverage under your plan for an approved condition like type 2 diabetes.
For the Bridge program, have your prescriber confirm you meet the BMI and condition rules and certify that you're using the drug as part of a diet-and-exercise lifestyle program.
Have the prescriber send the prescription for the specific covered drug (Foundayo, Wegovy, or the Zepbound KwikPen) to the pharmacy and, when requested, complete a prior authorization.
Check the drug against your plan's formulary on Medicare.gov or by calling the number on your plan card to confirm it's listed and learn your copay.
If it's denied or not covered, ask your plan how to file a formulary exception or appeal, and have your prescriber supply supporting medical records.
Common questions
How do I qualify for the $50 GLP-1 Bridge program copay?
You need Part D coverage, be 18 or older, and meet the BMI rules: a BMI of 35 or higher; a BMI of 30 or higher with a qualifying condition like diastolic heart failure, uncontrolled high blood pressure, or chronic kidney disease at stage 3a or higher; or a BMI of 27 or higher with a condition like prediabetes, a previous heart attack or stroke, or symptomatic peripheral artery disease. You also need a prescription and, when requested, a prior authorization, plus certification that you're using the drug as part of a diet-and-exercise lifestyle program. Only Foundayo, Wegovy, and the Zepbound KwikPen are currently covered at the $50 monthly copay.
What if my drug is denied for weight loss under my regular Part D plan?
If you don't qualify for the Bridge program and your plan excludes the drug for weight loss, you can file a formulary exception asking the plan to cover it, ideally with your prescriber documenting an approved medical reason. If it's still denied, you can appeal, but a weight-loss-only prescription on a standard plan is often paid out of pocket. Checking whether an approved non-weight-loss use applies is usually the more successful route.
Can I get the same drug covered if I also have type 2 diabetes?
Yes. If you have type 2 diabetes, moderate-to-severe sleep apnea, or fatty liver disease, you aren't eligible for the Bridge program, but your Part D plan might cover a GLP-1 for those conditions if it's on the formulary. In that case you typically pay your plan's normal cost sharing rather than the Bridge program's $50 copay. Ask your provider whether a GLP-1 is appropriate for your condition.
Does the Bridge program's $50 price apply before I hit my deductible?
The Bridge program is a separate, temporary benefit with a set $50 copay for a one-month supply for qualifying enrollees, distinct from your regular drug coverage. Because it's a separate Medicare program, the copay doesn't count toward your yearly Part D deductible or out-of-pocket limit, and it can't be lowered by Extra Help or spread out using the Medicare Prescription Payment Plan. Coverage requires a prescription and, when requested, prior authorization, plus participation in a diet-and-exercise program. Since it launched July 1, 2026 and is temporary, confirm current terms with Medicare.gov and your Part D plan.
Are compounded or older weight-loss pills like phentermine covered?
The Bridge program applies only to the specific listed GLP-1 drugs (Foundayo, Wegovy, and the Zepbound KwikPen), not to older oral weight-loss medications or compounded versions. Standard Part D plans have generally excluded drugs used purely for weight loss, so those often remain out of pocket. Coverage of any specific medication depends on your plan's formulary, so verify the exact drug name and strength.
