Medicare's Coverage of Wegovy Depends on Your Plan Type and Medical History

Medicare does not cover Wegovy (semaglutide) for weight loss alone. Original Medicare — the federal program run by the Centers for Medicare & Medicaid Services — does not pay for weight loss drugs, even when prescribed by your doctor. However, some Medicare Advantage plans (Part C) do cover Wegovy, and coverage rules vary widely by plan and by state. A few Medicare Advantage plans cover it for people with obesity and at least one weight-related condition like type 2 diabetes or heart disease. Others cover it only for diabetes management, not weight loss. Some cover it not at all.

The difference matters because your out-of-pocket cost could be anywhere from $0 to $1,300 per month depending on which plan you have and what your plan's rules are. You need to check your specific plan's formulary — the official list of drugs your plan will pay for — before you ask your doctor to prescribe it.

Key Takeaways

  • Original Medicare (Parts A and B) does not cover Wegovy or other GLP-1 drugs for weight loss under any circumstance.
  • Some Medicare Advantage plans cover Wegovy, but coverage rules differ by plan and state, so you must check your plan's formulary before requesting a prescription.
  • If your plan does cover Wegovy, you will likely pay a copay or coinsurance amount that depends on your plan's tier system, typically $50 to $250 per month.
  • Your doctor may need to submit a prior authorization request to your plan before the plan will agree to pay, which can take one to two weeks.
  • If your plan does not cover Wegovy, you can ask your doctor about other weight loss medications, switch to a different Medicare Advantage plan during open enrollment, or pay out of pocket.

How to Check Whether Your Plan Covers Wegovy

Start by finding your plan's formulary on your plan's website or by calling the customer service number on your insurance card. The formulary is a searchable list of every drug your plan covers. Search for "semaglutide" — that is the generic name for Wegovy — and note which tier it is on. Tier 1 drugs are usually the cheapest; Tier 4 or 5 drugs are the most expensive.

If you cannot find the formulary online or do not know your plan name, call your plan's customer service line and ask: "Does my plan cover semaglutide for weight loss?" Write down the answer and ask for the copay or coinsurance amount. If the representative is unsure, ask to speak with a pharmacist on the plan's team — they know the coverage rules better than most customer service staff.

Do not rely on your pharmacy to tell you whether your plan covers it. Pharmacies often do not know Medicare Advantage coverage rules and may give you wrong information. Your plan's customer service team is the only reliable source.

Prior Authorization: What Your Doctor Has to Do First

Even if your plan's formulary lists Wegovy, your plan may require prior authorization before it will pay. Prior authorization means your doctor has to submit paperwork to your plan explaining why you need the drug, and your plan has to approve it before you fill the prescription.

Your doctor's office handles this request — you do not submit it yourself. The process usually takes three to ten business days. During that time, your prescription is on hold. If your plan denies the request, your doctor can appeal, but that adds another one to two weeks.

Ask your doctor's office whether prior authorization is required for your plan before they write the prescription. If it is, ask them to submit the request right away so you do not have to wait longer than necessary.

What You Will Pay Out of Pocket

If your Medicare Advantage plan covers Wegovy, your out-of-pocket cost depends on your plan's cost-sharing structure. Most plans charge a copay — a flat dollar amount per prescription — or coinsurance — a percentage of the drug's cost. Copays for Wegovy typically range from $50 to $250 per month on Medicare Advantage plans that cover it. Some plans charge coinsurance of 20 to 30 percent, which can be higher.

Your plan may also have a deductible you have to meet before the plan starts paying. If your plan's deductible is $500 and you have not met it yet, you will pay the full price of Wegovy out of pocket until you reach $500 in total drug costs.

Once you reach your plan's out-of-pocket maximum for the year — usually $6,700 to $7,550 for Medicare Advantage plans — your plan pays 100 percent of covered drugs for the rest of that calendar year.

Original Medicare Does Not Cover Wegovy Under Any Circumstance

If you are on Original Medicare (Parts A and B), Wegovy is not covered, period. The Centers for Medicare & Medicaid Services does not pay for weight loss drugs. This is true even if you have type 2 diabetes and your doctor says Wegovy would help you manage your blood sugar. If Wegovy is prescribed for weight loss, Original Medicare will not pay.

If you are on Original Medicare and want to take Wegovy, you have two options: pay the full cost out of pocket, or switch to a Medicare Advantage plan that covers it. Switching plans is only possible during the Medicare Advantage open enrollment period, which runs from October 15 to December 7 each year. Outside that window, you cannot switch unless you have a may have access to life event like moving to a new state or losing other health coverage.

Other GLP-1 Drugs and Medicare Coverage

Wegovy is one of several GLP-1 drugs on the market. Others include Ozempic (also semaglutide), Mounjaro (tirzepatide), and Saxenda (liraglutide). Ozempic is approved by the FDA for type 2 diabetes, and some Medicare Advantage plans cover it for diabetes management. Mounjaro is also approved for diabetes. Saxenda is approved for weight loss.

Coverage for these drugs varies by plan, just as it does for Wegovy. If your plan does not cover Wegovy, ask your doctor whether they can prescribe a different GLP-1 drug that your plan does cover. Some plans cover Ozempic for diabetes but not Wegovy for weight loss, even though they are the same medication. Your doctor may be able to work within your plan's rules by prescribing for a covered condition instead.

What to Do If Your Plan Does Not Cover Wegovy

If your plan's formulary does not include Wegovy, or if your plan denies prior authorization, you have several options. First, ask your doctor whether they can appeal the denial. Plans sometimes reverse denials if your doctor provides additional medical information showing why you need the drug.

Second, ask your doctor about other weight loss medications your plan does cover. Phentermine, phendimetrazine, and some other older weight loss drugs are covered by more plans and are much cheaper. They work differently than GLP-1 drugs and may not be as effective for you, but they are an option worth discussing.

Third, if you are on Original Medicare, you can switch to a Medicare Advantage plan during open enrollment (October 15 to December 7) and choose a plan that covers Wegovy. Use the Medicare Plan Finder tool on Medicare.gov to search for plans in your area and filter by whether they cover semaglutide.

Fourth, you can pay out of pocket. Wegovy costs roughly $900 to $1,300 per month at retail price, though some manufacturers offer discount programs or coupons that can lower the cost.

Frequently Asked Questions

Will Medicare pay for Wegovy if I have type 2 diabetes?

Original Medicare will not cover Wegovy for any reason, including diabetes. Some Medicare Advantage plans cover it for people with diabetes and obesity together, but coverage varies by plan. Check your specific plan's formulary to know for certain.

Can I switch to a different Medicare plan to get Wegovy coverage?

Yes, but only during open enrollment from October 15 to December 7 each year. Outside that window, you cannot switch unless you have a may have access to life event. Use Medicare.gov's Plan Finder to see which plans in your area cover semaglutide before you switch.

What happens if my doctor prescribes Wegovy but my plan denies it?

Your doctor can file an appeal with your plan, usually within 30 days of the denial. The appeal process takes one to two weeks. If the appeal is denied, you can file a grievance with your plan or contact your state's health insurance information program for help.

Is there a cheaper alternative to Wegovy that Medicare covers?

Older weight loss medications like phentermine are covered by more Medicare plans and cost far less. They work differently than GLP-1 drugs, so talk to your doctor about whether they might work for you. Some Medicare Advantage plans also cover other GLP-1 drugs like Ozempic for diabetes management.

Do I have to pay the full price of Wegovy upfront, or can I pay monthly?

If your plan covers Wegovy, you pay your copay or coinsurance at the pharmacy when you fill the prescription each month. If you are paying out of pocket, Novo Nordisk (the manufacturer) offers a savings program that can reduce the cost to as low as $99 per month for people without insurance or whose insurance does not cover it.
