Medicare does not cover Zepbound, but some Medicare Advantage plans may offer it through their pharmacy benefit

Zepbound is a weight-loss medication (semaglutide) that the FDA approved in 2023. Original Medicare — both Part A and Part B — does not pay for Zepbound because it is a weight-management drug, and Original Medicare does not cover medications used only for weight loss. However, some Medicare Advantage plans (Part C) do include Zepbound in their formulary, which is the list of drugs they cover. Whether your plan covers it depends on which plan you have and which pharmacy you use.

If you have Original Medicare and want to explore Zepbound, you would pay the full cost out of pocket unless you also have a separate prescription drug plan (Part D) that covers it — which is rare, since Part D plans typically follow the same weight-loss exclusion. If you have a Medicare Advantage plan, contact your plan directly to ask whether Zepbound is on your formulary and what your out-of-pocket cost would be.

Key Takeaways

  • Original Medicare (Part A and Part B) does not cover Zepbound or any medication used primarily for weight loss.
  • Some Medicare Advantage plans include Zepbound in their formulary, but coverage varies by plan and by pharmacy.
  • If you have a Medicare Advantage plan, you must contact your plan's customer service to find out whether Zepbound is covered and what you would pay.
  • Zepbound costs several hundred dollars per month without insurance, and manufacturer discounts or patient information programs may lower the cost for people without coverage.

How Original Medicare handles weight-loss medications

Original Medicare excludes medications that are used only for weight management. This policy has been in place for decades and applies to all weight-loss drugs, including older medications like phentermine and newer ones like Zepbound and Wegovy (another brand name for semaglutide). The reasoning is that weight loss is considered a lifestyle goal rather than a treatment for a specific disease that Medicare covers.

This exclusion applies even if your doctor prescribes Zepbound for a medical reason related to weight — such as type 2 diabetes management or heart disease risk reduction. From Medicare's perspective, the drug's primary indication is weight loss, so it falls outside coverage. If you have Original Medicare and your doctor recommends Zepbound, you would need to pay the full cost yourself or look into other options.

What Medicare Advantage plans may cover

Medicare Advantage plans are run by private insurance companies and must cover everything Original Medicare covers, but they can also add extra benefits. Some Medicare Advantage plans have chosen to include Zepbound in their pharmacy formularies, particularly plans offered by larger insurers. However, not all plans do, and coverage can change from year to year.

If your Medicare Advantage plan does cover Zepbound, you will typically pay a copay or coinsurance amount rather than the full price. The amount you pay depends on which tier Zepbound is placed on in your plan's formulary — plans usually have three to five tiers, with higher tiers costing more. Some plans may also require prior authorization, meaning your doctor has to submit a request to the plan before you can fill the prescription.

To find out whether your specific plan covers Zepbound, call the customer service number on the back of your Medicare Advantage card. Have your plan name and member ID ready. Ask whether Zepbound is on the formulary, what tier it is on, what your copay or coinsurance would be, and whether prior authorization is required.

Medicare Part D and weight-loss drugs

Medicare Part D is the prescription drug coverage you can add to Original Medicare. Most Part D plans follow the same exclusion as Original Medicare and do not cover weight-loss medications. However, a small number of Part D plans may cover Zepbound, particularly if it is prescribed for a condition like type 2 diabetes where the drug has an approved use beyond weight loss.

If you have Original Medicare and a Part D plan, contact your Part D plan directly to ask whether Zepbound is covered. You can also review your plan's formulary online — each Part D plan publishes its formulary on its website, and you can search for Zepbound by name. If your plan does not cover it, you may be able to switch to a different Part D plan during the annual enrollment period (October 15 to December 7 each year).

Out-of-pocket cost and manufacturer support

Zepbound costs between $900 and $1,350 per month without insurance, depending on the pharmacy and whether you use a discount program. The manufacturer, Novo Nordisk, offers a savings card that can reduce the cost to as little as $99 per month for people without insurance or whose insurance does not cover the drug. You can find this program on Novo Nordisk's website or ask your pharmacist whether you may have access to.

Some community health centers and state Medicaid programs (which serve people under 65 with low income) do cover Zepbound, so if you are not yet on Medicare, that may be an option. Once you turn 65 and enroll in Medicare, coverage depends on whether you choose Original Medicare or a Medicare Advantage plan.

How to find out your plan's coverage

The fastest way to learn whether your plan covers Zepbound is to call your plan's customer service line. If you have Original Medicare, call 1-800-MEDICARE to confirm that Zepbound is not covered and to ask whether you have a Part D plan attached. If you have a Medicare Advantage plan, the number is on your insurance card. If you have a Part D plan, the number is also on your card.

When you call, have your member ID and plan name ready. Ask specifically: "Is Zepbound covered under my plan?" and "If yes, what is my copay or coinsurance, and do I need prior authorization?" Write down the answer and the name of the representative you spoke with in case you need to refer back to it.

You can also check your plan's formulary online. Most insurance companies post their formularies on their websites, and you can search by drug name. If you cannot find Zepbound listed, that usually means it is not covered, but calling to confirm is still a good idea because formularies are updated frequently.

What to do if your plan does not cover Zepbound

If your plan does not cover Zepbound, you have several options. First, talk to your doctor about whether there are other weight-loss medications that your plan does cover — some plans may cover older drugs like phentermine. Second, ask your doctor whether Zepbound might be covered under a different indication; for example, if you have type 2 diabetes, your doctor might be able to request prior authorization by emphasizing the diabetes management benefit rather than weight loss alone.

Third, look into the manufacturer's savings card mentioned above, which can bring the cost down significantly. Fourth, if you have a Medicare Advantage plan, you can switch to a different plan during the annual enrollment period (October 15 to December 7) if another plan in your area covers Zepbound. Finally, discuss with your doctor whether lifestyle changes, other medications, or other treatments might help you reach your health goals.

Frequently Asked Questions

Does Medicare Part B cover Zepbound?

No. Medicare Part B covers doctor visits and some outpatient services, but not weight-loss medications. Zepbound falls under the category of drugs that Medicare excludes because their primary use is weight management, not treatment of a specific disease.

Can I get Zepbound covered if my doctor says it is medically necessary?

Not under Original Medicare. Even if your doctor prescribes it for a medical reason — such as managing type 2 diabetes or reducing heart disease risk — Original Medicare still will not cover it because the drug's primary indication is weight loss. Some Medicare Advantage plans may cover it, and your doctor can request prior authorization, but there is no may provide.

What if I switch from Original Medicare to a Medicare Advantage plan?

You can switch during the annual enrollment period (October 15 to December 7) or if you may have access to for a special enrollment period. When you switch, you can compare plans to see which ones cover Zepbound. Call the plans you are considering and ask about Zepbound coverage before you enroll.

Is there a generic version of Zepbound that might be cheaper?

No. Zepbound is a brand name for semaglutide, and there is no generic version yet. The patent does not expire until 2031 or later, depending on the formulation. Wegovy is another brand name for the same drug, also made by Novo Nordisk, and has the same cost and coverage rules.

Can I use a GoodRx coupon or discount card with Medicare?

If you have Original Medicare without Part D, you can use a GoodRx coupon or similar discount card to reduce the cost of Zepbound at the pharmacy. If you have Part D or a Medicare Advantage plan, using a discount card instead of your insurance may actually cost you more, so ask your pharmacist to compare the price with your insurance copay first.
