Medicare's Coverage of Wegovy and Similar Weight Loss Drugs
Original Medicare (Parts A and B) does not cover Wegovy or other weight loss medications. Medicare considers these drugs to be for cosmetic purposes rather than treatment of a disease, which is why they fall outside standard coverage. However, Medicare Advantage plans (Part C) vary widely — some cover weight loss drugs and some do not, depending on the specific plan you chose.
If you take Wegovy through a Medicare Advantage plan that does cover it, you will typically pay a copay at the pharmacy, usually between $0 and $50 per month depending on your plan's formulary tier. The drug itself costs around $900 to $1,500 per month without insurance, so coverage through a plan that includes it can make a significant difference.
The landscape is still shifting. In 2024, a small number of Medicare Advantage insurers began adding GLP-1 drugs like Wegovy and Ozempic to their formularies, but this is not yet standard across the program. Your coverage depends entirely on which plan you have and which drugs that plan chose to include.
Key Takeaways
- Original Medicare does not cover Wegovy or other weight loss medications under any circumstances.
- Medicare Advantage plans may cover Wegovy, but coverage varies by plan and by insurer — you need to check your specific plan's formulary.
- If your plan does cover Wegovy, you will pay a copay rather than the full $900–$1,500 monthly cost.
- You can call your Medicare Advantage plan's customer service number (on your insurance card) to ask whether Wegovy is on your formulary and what your copay would be.
How to Check Your Medicare Advantage Plan's Coverage
The fastest way to find out whether your plan covers Wegovy is to call the customer service number on the back of your Medicare Advantage insurance card. Have your card in front of you and ask directly: "Is Wegovy covered under my plan, and what is the copay?" They can answer in minutes.
If you prefer to check online, log into your plan's member portal (usually accessible through the insurer's website) and search the formulary — the list of covered drugs. Look for semaglutide, which is the active ingredient in Wegovy. Some plans list it by brand name only, so search for both.
If Wegovy is not covered but your doctor believes you need a weight loss medication, ask your plan about prior authorization. Some insurers will cover the drug if your doctor submits paperwork showing medical necessity, such as a diagnosis of obesity combined with a weight-related condition like type 2 diabetes or high blood pressure.
What Original Medicare Covers Instead
If you are on Original Medicare and your doctor recommends weight loss treatment, Medicare will cover certain services but not the medications themselves. Original Medicare covers visits to your primary care doctor and referrals to a registered dietitian for medical nutrition therapy if you have diabetes, chronic kidney disease, or post-kidney transplant.
Medicare also covers bariatric surgery (weight loss surgery) under specific conditions: you must have a BMI of 35 or higher with an obesity-related condition, or a BMI of 40 or higher regardless of other conditions. Your doctor must document that you have tried and failed to lose weight through diet and exercise, and you must complete a psychological evaluation. The surgery itself, hospital stay, and follow-up care are covered.
Behavioral counseling for obesity is also covered under Original Medicare if your primary care doctor refers you. This is not the same as weight loss medication, but it is a covered service that may help.
Medicare Advantage Plans That May Cover Wegovy
As of early 2024, insurers adding Wegovy to their Medicare Advantage formularies include Humana, UnitedHealthcare, and Aetna, though not all of their plans include it — coverage depends on the specific plan you selected. Cigna, Anthem, and other major insurers have not yet broadly added weight loss drugs to their Medicare Advantage offerings, though this may change.
Even within a single insurer, coverage varies by plan. A Humana plan sold in one state may cover Wegovy while a different Humana plan in the same state does not. This is why checking your own plan's formulary is essential — you cannot assume coverage based on your insurer's name alone.
If you are shopping for a new Medicare Advantage plan during open enrollment (October 15 to December 7 each year), you can use the Medicare Plan Finder tool at Medicare.gov to compare plans. Search for "Wegovy" or "semaglutide" in the formulary section to see which plans in your area cover it.
Cost If Your Plan Does Not Cover Wegovy
If your Medicare Advantage plan does not cover Wegovy, you have a few options. You can pay out of pocket — the cost is approximately $900 to $1,500 per month depending on the pharmacy and whether you use a manufacturer discount card. Novo Nordisk, the company that makes Wegovy, offers a savings card that can reduce the cost to as low as $99 per month for some patients, though income limits explore.
You can also ask your doctor about generic alternatives. Semaglutide is available as a generic in some cases, and other GLP-1 drugs like tirzepatide (Zepbound) may have different coverage or pricing through your plan. Your doctor can help you explore which medications might work for your situation and what your actual costs would be.
Another option is to switch to a different Medicare Advantage plan during open enrollment if your current plan does not cover the medication and you believe you need it. You can change plans once per year during the annual enrollment period, and you can use the Medicare Plan Finder to see which plans in your area do cover Wegovy.
When to Talk to Your Doctor About Weight Loss Treatment
If you are considering Wegovy or another weight loss medication, start by talking to your primary care doctor. They can assess whether medication is appropriate for you based on your weight, overall health, and any conditions like diabetes or heart disease that might make weight loss especially important.
Your doctor can also help you understand the realistic timeline and expectations. Wegovy typically produces weight loss of 15 to 22 percent of body weight over about a year, but results vary. The medication works best when combined with diet and exercise changes, and you will need to stay on it to maintain the weight loss — if you stop, the weight often returns.
Ask your doctor these questions: Is weight loss medication right for me? If so, which medication? What are the side effects I should watch for? How often will I need to see you while taking it? What happens if my insurance does not cover it? Your doctor's answers will help you decide whether to pursue coverage through your plan or explore other options.
Frequently Asked Questions
Can I switch to a Medicare Advantage plan that covers Wegovy if my current plan does not?
Yes, during the annual open enrollment period from October 15 to December 7, you can switch to a different Medicare Advantage plan. Use the Medicare Plan Finder at Medicare.gov to search for plans in your area that cover Wegovy. You can change plans once per year during this window.
What if my doctor says I need Wegovy but my plan denies it?
You can request a coverage review, called an appeal. Your doctor will need to submit documentation showing medical necessity — for example, that you have obesity plus diabetes or heart disease. The plan has a set number of days to respond. If they deny the appeal, you can request an external review through Medicare.
Does Medicare cover any other weight loss medications besides Wegovy?
Original Medicare does not cover any weight loss medications. Some Medicare Advantage plans may cover other GLP-1 drugs like Ozempic (used for diabetes but also prescribed off-label for weight loss) or newer drugs like tirzepatide. Check your plan's formulary to see what is available.
If I have both Medicare and Medicaid, does Medicaid cover Wegovy?
Medicaid coverage of Wegovy varies by state. Some states cover it for people with obesity and related conditions, while others do not cover weight loss medications at all. Contact your state Medicaid program directly to ask about coverage in your state.
What is the difference between Wegovy and Ozempic?
Wegovy and Ozempic both contain semaglutide, but Wegovy is approved and marketed specifically for weight loss, while Ozempic is approved for type 2 diabetes. Some doctors prescribe Ozempic off-label for weight loss. If you have diabetes, your plan may cover Ozempic but not Wegovy, even though they are the same drug.
