Medicare's coverage of Wegovy depends on why your doctor prescribes it
Medicare Part D (prescription drug coverage) does not cover Wegovy when it is prescribed for weight loss alone. However, if your doctor prescribes Wegovy specifically to reduce the risk of heart attack or stroke in someone with heart disease or diabetes, coverage becomes possible — though it varies by your specific plan and whether your plan's formulary includes the drug.
The distinction matters because Wegovy (semaglutide) is approved by the FDA for two different purposes. When prescribed for weight management in people without heart disease, Medicare does not pay. When prescribed for cardiovascular risk reduction in people who already have heart disease or type 2 diabetes, some Medicare plans do cover it, but you need to check your own plan's formulary to know for certain.
Key Takeaways
- Medicare Part D may cover Wegovy only when prescribed for heart disease or cardiovascular risk reduction, not for weight loss alone.
- Your specific Medicare Part D plan decides whether Wegovy appears on its formulary, so two people with Medicare may have different coverage.
- You can check your plan's formulary on Medicare.gov or by calling the plan directly to learn whether Wegovy is covered and what your out-of-pocket cost would be.
- If your plan does not cover Wegovy, your doctor can request a coverage exception, though approval is not may provide.
- Some people find Wegovy more affordable through Medicare Part B if it is administered in a doctor's office rather than self-injected at home.
How Medicare Part D decides what drugs to cover
Each Medicare Part D plan creates its own list of covered medications, called a formulary. The plan decides which drugs to include based on cost, effectiveness, and how the drug is approved by the FDA. Because Wegovy has two FDA approvals — one for weight loss and one for cardiovascular risk reduction — a plan might cover it for one reason but not the other.
Plans also set different tier levels for drugs, which determine your out-of-pocket cost. A drug on a higher tier costs you more. Wegovy, when covered, is typically placed on a higher tier because it is expensive. You may pay 25 to 50 percent of the drug's cost, depending on your plan and which tier Wegovy is on.
The formulary can change each year, so a drug covered in 2024 might not be covered in 2025. This is why checking your current plan's formulary before your doctor writes a prescription is important.
Checking whether your specific plan covers Wegovy
The fastest way to find out is to visit Medicare.gov and use the Plan Finder tool. You will need your Medicare number and information about your current Part D plan. The tool shows you which drugs each plan covers and what your cost would be.
You can also call your Medicare Part D plan directly. The phone number is on your insurance card. Tell them you want to know whether Wegovy is on the formulary and, if it is, what tier it is on and what your copay or coinsurance would be. Ask specifically whether coverage applies when the drug is prescribed for heart disease or cardiovascular risk reduction.
If you do not yet have a Part D plan and are choosing one, you can compare plans based on Wegovy coverage using the same Plan Finder tool. This matters if your doctor has already told you that Wegovy might be part of your treatment plan.
What happens if your plan does not cover Wegovy
If Wegovy is not on your plan's formulary, you have several options. The first is to ask your doctor whether a different medication in the same class — such as Ozempic or Mounjaro — is covered instead. These drugs work similarly and may be on your plan's formulary.
The second option is to request a coverage exception from your plan. Your doctor submits a letter explaining why Wegovy is medically necessary for your specific condition and why alternatives would not work as well. The plan reviews the request and either approves or denies it. This process usually takes 24 to 72 hours for urgent requests and up to 14 days for standard requests. Approval is not may provide, but it is worth trying if your doctor believes Wegovy is the right choice for you.
The third option is to pay out of pocket. Wegovy costs between $900 and $1,350 per month without insurance, depending on the dose and where you fill the prescription. Some people use GoodRx or similar discount programs to lower the price, though these typically do not work with Medicare.
Medicare Part B coverage for Wegovy in a doctor's office
Medicare Part B covers some medications when they are administered in a doctor's office or hospital outpatient setting, rather than self-injected at home. Wegovy administered this way may be covered under Part B if your doctor prescribes it for heart disease or cardiovascular risk reduction and documents medical necessity.
Part B coverage works differently from Part D. You typically pay 20 percent of the approved amount after you meet your Part B deductible. This can be less expensive than Part D coverage for some people, especially if the drug is on a high tier in your Part D plan.
Ask your doctor whether administering Wegovy in the office is an option for your situation. Not all doctors' offices offer this, and it requires more frequent office visits than self-injection at home.
Understanding the FDA approvals that affect coverage
Wegovy received FDA approval in 2021 for chronic weight management in adults with obesity or overweight with weight-related conditions. This approval is the reason Medicare does not cover it for weight loss alone — the drug is not approved by Medicare for that purpose.
In 2023, Wegovy received a second FDA approval for reducing the risk of heart attack, stroke, and cardiovascular death in adults with heart disease and overweight or obesity. This approval opened the door to Medicare coverage for people with heart disease, because now the drug had a Medicare-covered indication.
Your doctor's prescription must specify the cardiovascular indication for Medicare to consider covering it. If the prescription says "for weight loss" or does not specify a reason, your plan may deny coverage even if you have heart disease. Make sure your doctor writes the prescription for the cardiovascular indication if that is why they are recommending the drug.
What to do if you and your doctor decide Wegovy is right for you
Start by checking your plan's formulary before your doctor writes the prescription. This saves time and prevents surprises at the pharmacy. If Wegovy is covered, ask your plan what your out-of-pocket cost will be and whether there are any prior authorization requirements.
If Wegovy is not covered, talk to your doctor about alternatives and whether a coverage exception is worth requesting. Bring your insurance card and plan information to the conversation so your doctor knows exactly what to include in the exception request.
Once you have a prescription, fill it at a pharmacy that participates in your Medicare Part D plan. If you use an out-of-network pharmacy, you will pay more or may not get any coverage at all.
Frequently Asked Questions
Does Medicare Part A or Part B cover Wegovy for heart disease?
Part A (hospital insurance) does not cover Wegovy. Part B may cover it if administered in a doctor's office or hospital setting, but most people receive Wegovy as a self-injection at home, which falls under Part D. Ask your doctor whether office administration is an option for you.
Will my Medigap or Medicare Advantage plan cover Wegovy differently?
Medicare Advantage plans (Part C) include prescription drug coverage as part of the plan, so coverage rules are similar to Part D — it depends on the plan's formulary. Medigap plans do not cover prescription drugs at all. Check your specific plan's formulary to know what you will pay.
What if my doctor says Wegovy is medically necessary but my plan denies the coverage exception?
You can appeal the denial. Your doctor can submit additional clinical information, or you can file a formal appeal with your plan. You also have the right to request an independent review through Medicare. The process takes longer but may result in coverage.
Can I switch Medicare plans to get Wegovy coverage?
Yes, during the annual open enrollment period (October 15 to December 7 each year), you can switch to a different Part D plan or Medicare Advantage plan. Use the Plan Finder tool to compare plans that cover Wegovy. You can also switch if you have a may have access to life event, such as moving to a new state.
Is there a generic version of Wegovy that might be cheaper?
Wegovy is a brand name for semaglutide. Generic semaglutide is available, and it may be covered by your plan at a lower cost. Ask your pharmacist or doctor whether generic semaglutide is an option and whether it would be covered under your plan.
