Does Medicare cover weight-loss drugs? It depends on why the drug was prescribed. Whether Medicare pays for a GLP-1 like Wegovy, Zepbound, Ozempic, or Mounjaro turns on the reason written on the prescription, not the brand on the box. If the prescription treats type 2 diabetes, moderate-to-severe sleep apnea, or fatty liver disease, medicare.gov says your Medicare drug plan should cover it. If the prescription is for weight reduction, Medicare points you somewhere else: a separate temporary program called the Medicare GLP-1 Bridge, which charges $50 a month but has eligibility rules of its own and does not start until a provider sets it up. This guide walks through each route, what you would pay, and what to do if your plan says no.

Does Medicare cover weight-loss drugs? The rule that decides coverage
The starting point is the reason on the prescription, not the brand on the box. Medicare.gov sends GLP-1 drugs down two different routes. A GLP-1 prescribed to treat type 2 diabetes, moderate-to-severe sleep apnea, or fatty liver disease is one medicare.gov says your Medicare drug plan should cover, so it runs through your regular Part D coverage. A GLP-1 prescribed for weight reduction runs through a separate temporary CMS program instead: the Medicare GLP-1 Bridge, which operates between July 1, 2026 and December 31, 2027.Centers for Medicare & Medicaid Services. (n.d.). Weight loss drugs. medicare.gov. Retrieved Jul 12, 2026, from https://www.medicare.gov/coverage/weight-loss-drugs
The split is visible in the drug names. Wegovy is on the Bridge's weight-reduction drug list; Ozempic and Mounjaro are not on that list at all. A GLP-1 that runs through Part D is handled by your Part D drug plan, which means the plan's own formulary and rules decide the outcome. Medicare.gov puts it two ways on the same page: your drug plan should cover GLP-1 medications for those three conditions, and your Part D plan might cover your GLP-1s. Neither phrasing is a guarantee about your specific plan, so check yours.Centers for Medicare & Medicaid Services. (n.d.). Weight loss drugs. medicare.gov. Retrieved Jul 12, 2026, from https://www.medicare.gov/coverage/weight-loss-drugs
When Part D covers a GLP-1: the medical indications
Medicare.gov names three conditions for which it says your Medicare drug plan should cover GLP-1 medications.Centers for Medicare & Medicaid Services. (n.d.). Weight loss drugs. medicare.gov. Retrieved Jul 12, 2026, from https://www.medicare.gov/coverage/weight-loss-drugs
- Type 2 diabetes. A GLP-1 prescribed to treat type 2 diabetes runs through your Part D diabetes coverage, subject to your plan's rules.
- Moderate-to-severe sleep apnea.
- Fatty liver disease.
Having one of those three conditions also puts you outside the Bridge, and for a reason that works in your favor: medicare.gov lists them as a reason you are not eligible for the Bridge precisely because your Medicare drug plan should cover the GLP-1 to treat them. The same logic covers people already on treatment. If you have been using a GLP-1 drug paid for by your Medicare drug plan, you are not eligible for the Bridge, but medicare.gov says you can keep getting your GLP-1 drug through your current plan.Centers for Medicare & Medicaid Services. (n.d.). Weight loss drugs. medicare.gov. Retrieved Jul 12, 2026, from https://www.medicare.gov/coverage/weight-loss-drugs
What a covered GLP-1 costs under Part D
When your Part D plan covers a GLP-1, it costs whatever your plan charges for that drug on its formulary, not the Bridge's flat copay. Two mechanics decide the number: your plan's rules for the drug, and the standard Part D benefit math.Centers for Medicare & Medicaid Services. (n.d.). Weight loss drugs. medicare.gov. Retrieved Jul 12, 2026, from https://www.medicare.gov/coverage/weight-loss-drugs
- Formulary and access rules. Plans place each covered GLP-1 on a cost tier and may attach prior authorization, step therapy, or quantity limits, so your prescriber may need to document the diagnosis before the plan pays. These rules vary by plan, which is why medicare.gov says only that your plan might cover your GLP-1s.Centers for Medicare & Medicaid Services. (n.d.). Weight loss drugs. medicare.gov. Retrieved Jul 12, 2026, from https://www.medicare.gov/coverage/weight-loss-drugs
- The benefit phases. Each plan sets its own deductible, up to a federal maximum of $615 in 2026, and some plans charge none; Extra Help lowers Part D deductibles for people with limited income and resources, so $615 is a ceiling rather than everyone's bill. After the deductible, you pay 25% coinsurance on covered drugs until your out-of-pocket spending reaches the annual cap of $2,100 for 2026, after which you pay $0 for covered Part D drugs for the rest of the calendar year. What counts toward that $2,100 is not only what you hand over at the counter: certain payments made on your behalf, such as payments through Extra Help, count toward it too, so an enrollee getting help reaches the cap earlier.Centers for Medicare & Medicaid Services.

If your covered GLP-1 is expensive enough to push your out-of-pocket spending on covered Part D drugs to $2,100, you pay nothing more for those drugs for the rest of the calendar year.Centers for Medicare & Medicaid Services.

How Medicare covers weight-loss drugs, by scenario
The table below distinguishes the common scenarios. The pathway, and the cost, depends on the reason the drug is prescribed and on which coverage you already have.
| Your situation | How Medicare handles it |
|---|---|
| GLP-1 prescribed for weight reduction | Medicare routes this use to the GLP-1 Bridge rather than to your Part D plan: $50 per one-month supply, if you meet the Bridge's eligibility rules (temporary; July 1, 2026 to Dec. 31, 2027) |
| GLP-1 prescribed to treat type 2 diabetes | Your Medicare drug plan should cover it, subject to the plan's own rules |
| GLP-1 prescribed to treat moderate-to-severe sleep apnea | Your Medicare drug plan should cover it, subject to the plan's own rules |
| GLP-1 prescribed to treat fatty liver disease | Your Medicare drug plan should cover it, subject to the plan's own rules |
| You already get a GLP-1 paid for by your Medicare drug plan | Not eligible for the Bridge, but you can keep getting the drug through your current plan |
| You have no Medicare drug coverage | Not eligible for the Bridge now; medicare.gov says that if you get Medicare drug coverage, you may become eligible |
The Medicare GLP-1 Bridge
For weight-reduction use, CMS has created the Medicare GLP-1 Bridge, a short-term demonstration. It gives eligible Medicare Part D beneficiaries access to certain GLP-1 drugs between July 1, 2026 and December 31, 2027, nationwide, including all states and U.S. territories. Its authority is section 402(a)(1)(A) of the Social Security Amendments of 1967, made applicable to Part D by section 1860D-42(b) of the Social Security Act.Centers for Medicare & Medicaid Services. (n.d.). Weight loss drugs. medicare.gov. Retrieved Jul 12, 2026, from https://www.medicare.gov/coverage/weight-loss-drugs
Who is eligible. This is the part that decides the answer for most readers, and it has three layers.Centers for Medicare & Medicaid Services. (n.d.). Weight loss drugs. medicare.gov. Retrieved Jul 12, 2026, from https://www.medicare.gov/coverage/weight-loss-drugs
- You need Medicare drug coverage. That means a standalone Medicare drug plan (PDP), a Medicare Advantage coordinated care plan with drug coverage (an MA-PD plan, including HMO, HMOPOS, and Local and Regional PPO plans), a Special Needs Plan (SNP), an Employer or union group waiver plan (EGWP), or the Limited Income Newly Eligible Transition (LI NET) program. If you have no Medicare drug coverage, you are not eligible now, but medicare.gov says that if you get Medicare drug coverage you may become eligible.
- You must be 18 or older, and meet one of three BMI tests when you start GLP-1 therapy: a body mass index of 35 or higher; a BMI of 30 or higher plus at least one of diastolic heart failure (heart failure with preserved ejection fraction), uncontrolled high blood pressure, or chronic kidney disease at stage 3a or higher; or a BMI of 27 or higher plus at least one of prediabetes, a previous heart attack or stroke, or blocked arteries in the legs or arms (peripheral artery disease) with symptoms.
- Two things disqualify you, and both leave a route open. If you already get GLP-1 drugs covered through your Medicare Part D plan, you are not eligible for the Bridge, but you can keep getting your GLP-1 drug through your current plan. If you have type 2 diabetes, moderate-to-severe sleep apnea, or fatty liver disease, you are not eligible for the Bridge, because your Medicare drug plan should cover GLP-1 medications to treat those conditions.
It does not happen on its own. Your doctor or other health care provider must send a prescription for a covered GLP-1 drug to the pharmacy and, when requested, complete a prior authorization, and your provider must certify that you are using the GLP-1 drug as part of a lifestyle program that focuses on diet and exercise. You then get a letter in the mail letting you know the drug is covered under the Bridge. The prior authorization is valid, including for refills and dose changes, through December 31, 2027, unless you change GLP-1s.Centers for Medicare & Medicaid Services. (n.d.). Weight loss drugs. medicare.gov. Retrieved Jul 12, 2026, from https://www.medicare.gov/coverage/weight-loss-drugs
What the $50 does and does not do. Eligible beneficiaries pay a $50 copayment at the pharmacy for a one-month supply, which is either 28 or 30 days depending on the drug. Because the drugs are furnished outside the Part D benefit's coverage and payment flow, the Part D deductible does not apply, no part of the $50 counts toward your true out-of-pocket (TrOOP) costs or your Part D out-of-pocket limit, and the copay does not appear on a Part D Explanation of Benefits or a Medicare Summary Notice. There is no low-income subsidy provided under the Bridge, so if you have Extra Help you pay the full $50 rather than the reduced amount Extra Help would normally bring a covered Part D drug down to.Centers for Medicare & Medicaid Services. (n.d.). Weight loss drugs. medicare.gov. Retrieved Jul 12, 2026, from https://www.medicare.gov/coverage/weight-loss-drugs
The drugs. Starting July 1, 2026, the Bridge covers Foundayo (tablet), Wegovy (injection or tablet), and Zepbound in the KwikPen formulation only.

Retrieved Jul 12, 2026, from https://www.medicare.gov/coverage/weight-loss-drugs
One structural point worth knowing if your plan tells you it does not participate: because the drugs sit outside the Part D benefit payment flow, Part D sponsors carry no risk for them and do not have to opt in for eligible beneficiaries to access them. In 2026, CMS uses a single central processor to manage prior authorization, claims adjudication, and payment to pharmacies. That is a statement about plans, not about you, so it does not remove your own eligibility and prior-authorization steps above.Centers for Medicare & Medicaid Services. (n.d.). Weight loss drugs. medicare.gov. Retrieved Jul 12, 2026, from https://www.medicare.gov/coverage/weight-loss-drugs
This is a fast-moving area of policy, and the Bridge is a temporary demonstration scheduled to end after December 31, 2027.

What if your plan denies or restricts the drug?
If your Part D plan requires prior authorization for a GLP-1, or denies it, you have a defined path. Part D drug decisions follow a five-level appeals process that begins with your own plan, and plans must offer a faster track when waiting for a standard decision could seriously jeopardize your life, health, or ability to regain maximum function.Centers for Medicare & Medicaid Services.

Check your plan's formulary first
Use the Medicare Plan Finder at medicare.gov or call your plan to confirm whether your GLP-1 is on the formulary and what prior-authorization, step-therapy, or quantity rules apply.
Ask your prescriber to document the indication
If prior authorization is required, your doctor submits the diagnosis and clinical justification, for example type 2 diabetes or moderate-to-severe sleep apnea. This is often what turns a denial into an approval. For a Bridge drug, your provider must also certify that you are using the GLP-1 as part of a lifestyle program focused on diet and exercise.Centers for Medicare & Medicaid Services. (n.d.). Weight loss drugs. medicare.gov. Retrieved Jul 12, 2026, from https://www.medicare.gov/coverage/weight-loss-drugs
Request a coverage determination
Ask the plan in writing for a coverage determination or an exception (for a non-formulary drug or to waive a restriction). You can request an expedited decision, generally issued within 72 hours, if waiting could seriously jeopardize your health.Centers for Medicare & Medicaid Services. (n.d.). Appeals in Original Medicare. medicare.gov. Retrieved Jul 15, 2026, from https://www.medicare.gov/providers-services/claims-appeals-complaints/appeals/original-medicare
Appeal a denial
If the plan says no, appeal: Level 1 is a redetermination of the coverage determination by the plan, Level 2 is review by an Independent Review Entity, and further levels go to an Administrative Law Judge at the Office of Medicare Hearings and Appeals, the Medicare Appeals Council, and federal district court.

Frequently Asked Questions
Does Medicare cover Ozempic or Wegovy for weight loss?
It depends on the drug and on the reason for the prescription. For weight reduction, Medicare's route is the Medicare GLP-1 Bridge rather than your Part D plan, and the Bridge's drug list is short: Foundayo (tablet), Wegovy (injection or tablet), and Zepbound (KwikPen only). Wegovy is on that list; Ozempic is not. The Bridge's $50 copay is also not open to everyone, since you must have Medicare drug coverage, be 18 or older, meet one of its BMI tests, and have a provider complete a prior authorization and certify you are in a lifestyle program focused on diet and exercise. If a GLP-1 is prescribed instead to treat type 2 diabetes, moderate-to-severe sleep apnea, or fatty liver disease, medicare.gov says your Medicare drug plan should cover it.Centers for Medicare & Medicaid Services.

What is the Medicare GLP-1 Bridge and how much does it cost?
The Medicare GLP-1 Bridge is a short-term CMS demonstration that gives eligible Medicare Part D beneficiaries access to certain GLP-1 drugs between July 1, 2026 and December 31, 2027, nationwide. The copay is $50 for a one-month supply, either 28 or 30 days depending on the drug. Because the drugs are furnished outside the Part D benefit payment flow, the Part D deductible does not apply and no part of the $50 counts toward your out-of-pocket limit. It is not automatic: your provider must send the prescription to the pharmacy, complete a prior authorization when requested, and certify that you are using the drug as part of a lifestyle program focused on diet and exercise, after which you get a letter confirming coverage.Centers for Medicare & Medicaid Services.

Will Medicare cover a GLP-1 for my diabetes?
Medicare.gov says your Medicare drug plan should cover GLP-1 medications to treat type 2 diabetes, and the same page says your Part D plan might cover your GLP-1s. Both phrasings point to the same place: your own plan's formulary and its prior-authorization, step-therapy, and cost-sharing rules decide, so confirm it with your plan rather than assuming.
