Most Medicare Advantage plans do not cover Wegovy, but some do — and the rules vary widely by plan and state

Wegovy (semaglutide) is a prescription injection for weight management. Medicare Part B does not cover it. Most Medicare Advantage plans follow the same rule, but a small number of plans in certain states have begun covering it under specific conditions. Whether your plan covers it depends on which plan you chose, which state you live in, and whether you meet that particular plan's requirements — usually a documented diagnosis of obesity plus other health conditions like diabetes or heart disease.

The fastest way to know is to call the customer service number on your Medicare Advantage card and ask directly: "Does my plan cover Wegovy?" Have your member ID ready. If the answer is no, ask whether your plan covers any other weight-loss medications, because some plans cover alternatives like phentermine or naltrexone-bupropion.

Key Takeaways

  • Medicare Part B does not cover Wegovy, and most Medicare Advantage plans follow that same rule.
  • A small number of Medicare Advantage plans in select states have started covering Wegovy, but only for members who meet specific medical requirements.
  • Your plan's coverage depends on which plan you chose and which state you live in — there is no single Medicare Advantage rule.
  • Call your plan's customer service line to ask about coverage before you talk to your doctor, because knowing the answer changes whether a prescription makes sense.
  • If your plan does not cover Wegovy, ask whether it covers other weight-loss medications, which may have different coverage rules.

Why Medicare Part B and most Medicare Advantage plans exclude Wegovy

Medicare Part B covers prescription drugs only if they treat a disease or condition. Obesity is classified as a disease, but Medicare's rules have historically treated weight-loss medications as optional rather than medically necessary. Wegovy was approved by the FDA in 2021 for chronic weight management, but Medicare did not add it to its covered drugs list.

Medicare Advantage plans are required to cover everything that Medicare Part B covers, but they can also add their own coverage. Most plans have chosen not to add Wegovy because of its cost — a month's supply runs between $900 and $1,350 before any discounts — and because the long-term medical benefit is still being studied in older adults.

This does not mean no Medicare Advantage plan covers it. Some regional and national plans have made the decision to cover Wegovy for members who meet strict criteria, usually because they have obesity plus a related condition like type 2 diabetes, heart disease, or chronic kidney disease. These plans are the exception, not the rule.

Which Medicare Advantage plans cover Wegovy and how to find out

There is no public list of which Medicare Advantage plans cover Wegovy. Coverage decisions are made by individual insurers and can change year to year. Some plans that covered it in 2024 may not in 2025, and new plans may add it. The only reliable way to know is to contact your plan directly.

Call the customer service number on your Medicare Advantage card. Tell them you want to know whether Wegovy is covered under your plan. Ask for the answer in writing if possible, because coverage rules can be complex and a written confirmation protects you if there is a billing dispute later. If your plan does cover it, ask what the out-of-pocket cost will be and whether you need prior authorization from your doctor.

If you are still shopping for a Medicare Advantage plan and weight-loss medication coverage matters to you, you can call plans directly during the open enrollment period (October 15 to December 7 each year) and ask about their Wegovy policy before you join. Some plans will tell you; others will not commit to coverage decisions for future members.

What requirements your plan may impose if it does cover Wegovy

Plans that cover Wegovy typically require all of the following: a diagnosis of obesity (usually defined as a BMI of 30 or higher), at least one related health condition (such as type 2 diabetes, high blood pressure, heart disease, or sleep apnea), and documentation that you have tried other weight-loss methods first, such as diet and exercise or other medications.

Many plans also require prior authorization, meaning your doctor must submit a request to the plan before you fill the prescription. The plan reviews the request and either approves it or denies it. This process usually takes 3 to 5 business days. If the plan denies it, your doctor can appeal, but that adds time.

Some plans limit how much they will pay — for example, covering only the lowest-dose pen or requiring you to pay a percentage of the cost as a copay or coinsurance. Ask your plan for the exact out-of-pocket amount you would owe per month before your doctor writes the prescription.

What to do if your plan does not cover Wegovy

If your Medicare Advantage plan does not cover Wegovy, you have several options. The first is to ask your doctor whether your plan covers any other weight-loss medications. Some plans cover phentermine (a stimulant), naltrexone-bupropion (Contrave), or orlistat (Xenical), which work differently than Wegovy but may help. These older medications are sometimes covered because they have been around longer and cost less.

The second option is to pay for Wegovy out of pocket. The manufacturer, Novo Nordisk, offers a savings program called Wegovy Savings Card that can reduce the cost to as low as $99 per month for may be able to access people. You do not need insurance to use it. Visit Novo Nordisk's website or ask your doctor's office for details.

The third option is to switch to a different Medicare Advantage plan during the next open enrollment period if you find one in your area that does cover Wegovy. You can change plans once per year, from October 15 to December 7. Use the Medicare Plan Finder tool on Medicare.gov to see which plans are available in your zip code and call them to ask about Wegovy coverage before you switch.

How Wegovy coverage differs from other weight-loss treatments

Medicare and most Medicare Advantage plans treat weight-loss medications differently than they treat weight-loss surgery. Bariatric surgery (gastric bypass, gastric sleeve, lap-band) is covered by Medicare Part B and most Medicare Advantage plans if you meet medical criteria, because it is considered a treatment for obesity-related diseases rather than a cosmetic procedure. Wegovy, by contrast, is still classified as optional by most plans.

Behavioral weight-loss programs, such as supervised diet and exercise programs, are also covered differently. Medicare covers a program called Intensive Behavioral Therapy for Obesity if your doctor refers you and you have a BMI of 30 or higher. This is free under Part B. Many Medicare Advantage plans cover it as well. This program does not involve medication but may be a covered alternative if your plan does not cover Wegovy.

Frequently Asked Questions

Can I use a prescription discount card to pay for Wegovy if my Medicare Advantage plan does not cover it?

Yes. Prescription discount cards like GoodRx, SingleCare, or Walmart's discount program work independently of insurance and can lower the price of Wegovy. Compare prices on these sites before you fill the prescription. The manufacturer's Wegovy Savings Card often offers a lower price than discount cards, so check both.

What happens if my plan covers Wegovy but then stops covering it mid-year?

Plans can change their formulary (the list of covered drugs) during the year, though it is uncommon. If your plan stops covering Wegovy while you are taking it, you have the right to request a continuity-of-care exception, which allows you to keep the medication at the same cost-sharing level for a limited time while you and your doctor find an alternative. Contact your plan's customer service to request this.

Does Medicare Advantage cover Ozempic for weight loss?

Ozempic is the same medication as Wegovy but is prescribed for type 2 diabetes. Medicare Advantage plans cover Ozempic for diabetes because it treats a disease. If you have diabetes and your doctor prescribes Ozempic, your plan will likely cover it even if it does not cover Wegovy. However, using Ozempic for weight loss alone (without diabetes) is off-label, and coverage rules may differ.

If I switch to Original Medicare, will it cover Wegovy?

No. Original Medicare Part B does not cover Wegovy. If you are considering switching from Medicare Advantage to Original Medicare, weight-loss medication coverage should not be a factor in that decision, because neither option covers it through Medicare.

Can I appeal if my plan denies coverage for Wegovy?

Yes. If your plan denies prior authorization for Wegovy, your doctor can file an appeal. The plan must respond within 72 hours for urgent appeals or 30 days for standard appeals. Your doctor can argue that you meet the plan's criteria or that the denial is medically unreasonable. If the plan upholds the denial, you can file a complaint with your state's insurance commissioner.
