Medicare does not cover Wegovy, but some Medicare Advantage plans may cover similar medications

Wegovy is a brand-name injectable medication containing semaglutide, prescribed for weight loss in adults with obesity or overweight with weight-related health conditions. Original Medicare (Parts A and B) does not cover Wegovy or any weight-loss drugs. However, some Medicare Advantage plans (Part C) do cover semaglutide or other GLP-1 receptor agonists, though coverage rules and costs vary widely by plan and by year.

Whether you can get coverage depends on which type of Medicare you have, which specific plan you're enrolled in, and whether your doctor documents that the medication is medically necessary for a condition like type 2 diabetes or heart disease — not just for weight loss alone.

Key Takeaways

  • Original Medicare (Parts A and B) does not cover Wegovy or any weight-loss medications under any circumstances.
  • Some Medicare Advantage plans cover semaglutide, but you must check your specific plan's formulary and call the plan directly to learn the current rules.
  • Coverage often requires your doctor to document a medical reason beyond weight loss, such as type 2 diabetes or heart disease.
  • If your plan does not cover Wegovy, your doctor may prescribe a generic semaglutide or a different GLP-1 medication that your plan does cover.
  • Wegovy costs between $900 and $1,350 per month without insurance, and prices change frequently.

Why Original Medicare does not cover weight-loss drugs

Original Medicare (Parts A and B) classifies weight-loss medications as treatments for a cosmetic or lifestyle concern, not a covered medical service. This policy has remained in place for decades and applies to all weight-loss drugs, including Wegovy, Ozempic (when prescribed for weight loss), Saxenda, and phentermine.

The one exception is if semaglutide is prescribed for type 2 diabetes management under the brand name Ozempic rather than Wegovy. In that case, Original Medicare may cover it as a diabetes medication. Your doctor would need to prescribe Ozempic specifically and document that the primary reason is blood sugar control, not weight loss.

How Medicare Advantage plans handle Wegovy and semaglutide

Medicare Advantage plans are run by private insurance companies and set their own coverage rules within Medicare guidelines. Some plans do cover semaglutide or other GLP-1 medications, but the rules differ from plan to plan and can change each year during the annual open enrollment period.

Coverage typically depends on three things: whether the medication is on your plan's formulary (the list of covered drugs), what tier it sits on (which determines your out-of-pocket cost), and whether your doctor can show medical necessity. Many plans require prior authorization, meaning your doctor must submit paperwork to the plan before you fill the prescription, and the plan must approve it first.

Some plans cover semaglutide only when it is prescribed for type 2 diabetes or heart disease, not for weight loss alone. Others may cover it for weight loss if you meet specific criteria, such as a BMI above a certain threshold or documented weight-related health problems. A few plans cover it with no restrictions beyond the prior authorization step.

How to learn about your plan covers Wegovy

The fastest way is to call your Medicare Advantage plan's customer service number, which is on your insurance card. Tell them you want to know whether semaglutide (Wegovy) is covered, what tier it is on, whether prior authorization is required, and what your out-of-pocket cost would be. Write down the name of the representative and the date of the call in case you need to reference it later.

You can also check your plan's formulary online. Log into your plan's website or call and ask them to mail or email you the current formulary. Search for "semaglutide" and look at which tier it is listed under. Tier 1 usually costs the least; Tier 4 or 5 usually costs the most. If semaglutide is not listed at all, it is not covered.

If you are still in the decision phase and have not yet chosen a Medicare Advantage plan, you can compare formularies during open enrollment (October 15 to December 7 each year). Use the Medicare Plan Finder tool at Medicare.gov, enter your medications, and it will show you which plans in your area cover them.

What to do if your plan does not cover Wegovy

If your Medicare Advantage plan does not cover Wegovy, ask your doctor whether a different medication on your plan's formulary might work for you. Many plans cover other GLP-1 receptor agonists such as Trulicity (dulaglutide) or Mounjaro (tirzepatide), which work similarly to Wegovy. Your doctor can also prescribe generic semaglutide, which may be covered at a lower cost than the brand-name Wegovy.

If you have Original Medicare and want to explore semaglutide, talk to your doctor about whether Ozempic (prescribed for diabetes) makes sense for your health situation. If you have type 2 diabetes, Original Medicare may cover Ozempic as a diabetes treatment.

Another option is to ask your doctor about a patient information program run by the drug manufacturer. Novo Nordisk, which makes Wegovy, offers programs that can reduce or eliminate your out-of-pocket cost if your income falls below certain thresholds. Your doctor's office can help you explore.

Out-of-pocket costs if your plan does cover Wegovy

If your Medicare Advantage plan does cover Wegovy, your cost depends on which tier the drug is on and your plan's deductible. Some plans have no deductible for prescription drugs; others require you to meet a deductible before coverage kicks in. Once you meet the deductible, you typically pay a copay (a flat amount like $35 or $50) or coinsurance (a percentage of the drug's cost).

Wegovy is a monthly injection, so you would pay your copay or coinsurance once per month. If your plan places it on a high tier, your monthly cost could be $100 to $300 or more. Some plans have a maximum out-of-pocket limit; once you hit that limit in a calendar year, the plan covers the rest of your drugs at no cost to you.

Questions to ask your doctor before pursuing Wegovy

Before you ask your doctor to prescribe Wegovy, it helps to understand whether it is the right medication for your situation. Ask your doctor: Is Wegovy appropriate for my health conditions? Are there other medications I should consider first? What results can I realistically expect, and over what timeframe? What are the side effects, and which ones should prompt me to call you? If my insurance does not cover it, what are my other options?

Also ask whether your doctor has experience prescribing semaglutide and whether they can help you navigate the prior authorization process if your plan requires it. Some doctors' offices have staff who specialize in working with insurance companies on these requests.

Frequently Asked Questions

Can I switch to a different Medicare Advantage plan mid-year to get Wegovy coverage?

No. You can change Medicare Advantage plans only during the annual open enrollment period (October 15 to December 7) or if you may have access to for a special enrollment period due to a life event like moving or losing other coverage. If you need Wegovy urgently and your current plan does not cover it, talk to your doctor about alternative medications your plan does cover.

If I have Original Medicare and a Medigap plan, will Medigap cover Wegovy?

No. Medigap plans cover only what Original Medicare covers. Since Original Medicare does not cover weight-loss drugs, Medigap will not either. However, if you have Original Medicare and a separate prescription drug plan (Part D), that plan may cover semaglutide if it is prescribed for diabetes under the brand name Ozempic.

What if my doctor says Wegovy is medically necessary but my plan denies it?

You have the right to appeal the denial. Ask your plan for the appeal process and the important date. Your doctor can submit additional documentation explaining why they believe the medication is medically necessary. If the plan denies the appeal, you can request an independent review through Medicare. Your plan must tell you how to request this review.

Does Medicare cover weight-loss surgery instead?

Original Medicare covers bariatric surgery (weight-loss surgery) in limited cases when you meet specific criteria, including a BMI of 35 or higher with weight-related health conditions, or a BMI of 40 or higher. Medicare Advantage plans may have different rules. Ask your plan or your doctor whether surgery is an option for you and whether it would be covered.

Will Wegovy be covered by Medicare in the future?

Medicare's coverage policies change slowly and are set by Congress and the Centers for Medicare and Medicaid Services (CMS). There is ongoing discussion about whether weight-loss medications should be covered, but no change to Original Medicare's policy has been announced. Check Medicare.gov or ask your doctor's office to stay informed about any policy changes.
