What Medicare covers for semaglutide
Medicare Part D covers semaglutide, but only when prescribed for type 2 diabetes. If your doctor prescribes it for weight loss alone, Medicare will not pay for it. The distinction matters because semaglutide is sold under two brand names: Ozempic (for diabetes) and Wegovy (for weight loss), and Medicare treats them differently.
If you have type 2 diabetes and your doctor prescribes Ozempic, your Part D plan will likely cover it, though you will pay a copay or coinsurance. The exact amount depends on which tier your plan places the drug on — most plans put semaglutide on a higher tier, meaning your out-of-pocket cost will be substantial. You can check your specific plan's formulary (the list of covered drugs) on Medicare.gov or by calling the plan directly.
If you are taking semaglutide only for weight loss without a diabetes diagnosis, you will need to pay the full cost out of pocket. A month's supply of Wegovy typically costs between $900 and $1,400 before any discounts, though some pharmacies and the manufacturer offer savings programs that can lower this.
Key Takeaways
- Medicare Part D covers semaglutide (Ozempic) when prescribed for type 2 diabetes, but not when prescribed for weight loss alone (Wegovy).
- Your out-of-pocket cost for covered semaglutide depends on your specific Part D plan's formulary tier and your annual deductible status.
- If semaglutide is prescribed only for weight loss, you pay the full pharmacy price unless you use a manufacturer discount program.
- Some people with obesity and other conditions like heart disease may have coverage options through Medicare Advantage plans, which vary by plan.
How Medicare Part D formularies determine coverage
Each Part D plan creates its own formulary — a list of covered medications organized into tiers. Tier 1 drugs cost the least; Tier 5 drugs cost the most. Semaglutide typically lands on Tier 3 or Tier 4, meaning you will pay more than you would for a common diabetes pill.
Your plan may also require prior authorization, which means your doctor must submit paperwork to the insurance company explaining why you need semaglutide instead of a cheaper alternative. This can delay your prescription by a few days to a week. Some plans also impose a quantity limit — for example, allowing only one pen per month — which matches the standard dosing schedule.
To find out what your plan covers, log into your Medicare account at Medicare.gov, search for your plan name, and view the formulary. You can also call your plan's customer service number, which is on your insurance card. Have your doctor's name and the medication name ready when you call.
Medicare Advantage plans and weight loss coverage
Medicare Advantage (Part C) plans are run by private insurers and can cover drugs that Original Medicare does not. Some Advantage plans have begun covering semaglutide or similar drugs for weight loss in people who also have obesity-related conditions like heart disease, sleep apnea, or joint problems. Coverage varies widely by plan and by state.
If you are enrolled in a Medicare Advantage plan and interested in semaglutide for weight loss, contact your plan directly to ask whether it covers weight loss medications and what conditions must be present. Your doctor may need to document that you have one of these conditions and that you have tried other weight loss methods first. Plans that do cover it typically still require prior authorization and may limit which patients receive it.
If you are considering switching to a Medicare Advantage plan specifically for weight loss medication coverage, remember that you can only change plans during the annual enrollment period (October 15 to December 7) or if you experience a may have access to life event. Switching plans also means changing your doctors and pharmacies, so weigh that against the medication benefit.
What to pay out of pocket for semaglutide
If Medicare covers your semaglutide prescription, your out-of-pocket cost includes your annual Part D deductible (which varies by plan but is typically $505 in 2024) plus your copay or coinsurance for the drug itself. Once you reach the coverage gap (sometimes called the "donut hole"), you pay a higher percentage until you hit your plan's out-of-pocket maximum.
For a drug on Tier 3 or Tier 4, copays often range from $35 to $100 per month, though coinsurance (a percentage of the drug's cost) can be higher. Because semaglutide is expensive, you may hit your out-of-pocket maximum partway through the year, after which Medicare covers a larger share for the rest of the year.
If you cannot afford the copay, ask your doctor or pharmacist about patient information programs. Novo Nordisk, the manufacturer of Ozempic and Wegovy, offers a savings card that can reduce your copay to as little as $25 per month if you have commercial insurance or are uninsured. Medicare beneficiaries cannot use this card, but some state pharmaceutical information programs may help.
Other weight loss medications Medicare may cover
If semaglutide is not covered or is too expensive, other weight loss medications may be options. Phentermine, an older appetite suppressant, is often covered by Part D plans at a much lower cost because it is a generic drug. It works differently than semaglutide and is typically prescribed for short-term use (12 weeks or less).
Orlistat, which reduces fat absorption in the digestive system, is available over the counter and does not require a prescription, so Medicare does not cover it — but it costs around $20 to $30 per month at most pharmacies. Your doctor can discuss whether either of these is appropriate for your situation.
Some Medicare Advantage plans also cover behavioral weight loss programs, nutritionist visits, or gym memberships, which may be covered even if the medication itself is not. Ask your plan what non-medication weight loss support is available to you.
Questions to ask your doctor and Medicare plan
Before your doctor prescribes semaglutide, ask whether it is being prescribed for diabetes or for weight loss, because that determines whether Medicare will cover it. If it is for diabetes, ask your doctor to submit a prior authorization request to your Part D plan so you know the coverage decision before you go to the pharmacy.
Contact your Part D plan and ask: Is semaglutide on the formulary? If so, what tier? Do I need prior authorization? Is there a quantity limit? What is my copay or coinsurance? What is my annual deductible, and have I met it yet? If your plan does not cover it, ask whether there is an appeals process or whether switching to a different plan during open enrollment would give you coverage.
If cost is a barrier, tell your doctor. They may be able to prescribe a different medication, adjust the dose to lower your copay, or help you find a patient information program. Do not stop taking a prescribed medication without talking to your doctor first.
When to seek help with coverage decisions
If your Part D plan denies coverage for semaglutide, you have the right to appeal. Your doctor can submit additional information explaining why the drug is medically necessary for you. The appeal process usually takes 30 to 60 days.
If you need help understanding your coverage or filing an appeal, contact your State Health Insurance information Program (SHIP). SHIP offers free counseling to Medicare beneficiaries. You can find your state's SHIP by calling 1-877-839-2675 or visiting shiptalk.org.
If you are struggling to afford any medication, also ask your doctor's office about samples. Pharmaceutical companies sometimes provide free samples to doctors' offices, and your doctor may have semaglutide samples available.
Frequently Asked Questions
Will Medicare cover semaglutide if I have prediabetes?
No. Medicare Part D covers semaglutide only for people with a type 2 diabetes diagnosis. Prediabetes does not meet the coverage requirement. If your doctor believes semaglutide would benefit you, you would need to pay out of pocket or explore whether a Medicare Advantage plan in your area covers it for prediabetes, which is rare.
Can I use a GoodRx coupon or manufacturer discount card with Medicare?
No. Medicare rules prohibit using third-party discount cards or coupons at the pharmacy when you present your Medicare card. However, if you are uninsured or paying out of pocket for Wegovy, you can use the manufacturer's savings card or GoodRx to reduce the cost. Ask your pharmacist which option gives you the lowest price.
What happens to my semaglutide coverage if I switch Medicare plans?
Coverage depends on your new plan's formulary. If you switch to a different Part D plan during open enrollment, check the new plan's formulary before you enroll to confirm semaglutide is covered and at what tier. If you switch to a Medicare Advantage plan, coverage may be different or may require prior authorization. Always verify coverage before your current plan ends.
Does Medicare cover semaglutide for heart disease or weight loss related to heart disease?
Original Medicare Part D does not. Some Medicare Advantage plans have begun covering semaglutide for weight loss in people with heart disease, but this is not standard across all plans. Contact your specific plan to ask whether this coverage is available to you.
What if my doctor prescribes Wegovy instead of Ozempic?
Wegovy is the brand name for semaglutide prescribed for weight loss, and Medicare does not cover it. If your doctor prescribes Wegovy, you will pay the full pharmacy price unless you use a manufacturer discount program or have a Medicare Advantage plan that covers weight loss medications. Ask your doctor whether Ozempic (for diabetes) would be appropriate for your situation if cost is a concern.
