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

Original Medicare — the federal program run by the Centers for Medicare & Medicaid Services — does not pay for Wegovy (semaglutide) or other weight-loss medications. Original Medicare covers medications only if the Food and Drug Administration has approved them to treat a disease or condition, and weight loss itself is not classified as a disease in Medicare's rules.

However, some Medicare Advantage plans (Part C plans run by private insurance companies) do cover Wegovy, usually when a doctor documents that you have obesity plus a related condition like type 2 diabetes, heart disease, or high blood pressure. Coverage varies widely by plan and by state, and some plans that cover it may require prior authorization or place it on a restricted formulary tier with a high copay.

If you have Original Medicare and want to explore weight-loss medication, you would pay the full cost out of pocket, though some manufacturers offer patient information programs that reduce the price.

Key Takeaways

  • Original Medicare does not cover Wegovy or other weight-loss drugs under any circumstances.
  • Some Medicare Advantage plans cover Wegovy when you have obesity plus a related health condition, but coverage rules differ by plan and state.
  • If your Medicare Advantage plan covers Wegovy, you will likely need your doctor to request prior authorization before you fill the prescription.
  • The manufacturer Novo Nordisk offers a savings program that may reduce your out-of-pocket cost if Medicare does not cover the drug.

How to learn about your specific plan covers Wegovy

The fastest way is to call the customer service number on the back of your insurance card and ask directly: "Does my plan cover Wegovy, and if so, what is the copay and do I need prior authorization?" Have your member ID ready. Write down the name of the representative and the date you called, in case you need to reference the conversation later.

You can also check your plan's formulary — the official list of covered medications — on your plan's website or by requesting a printed copy. Search for "semaglutide" (the generic name for Wegovy) rather than the brand name, since some formularies list it that way. If you see it listed, note which tier it is on: Tier 1 or 2 usually means a lower copay, while Tier 3 or 4 means a higher one.

If your plan does cover it, ask whether your doctor needs to submit a prior authorization request before you can fill the prescription. Some plans require the doctor to document that you meet certain criteria — usually a BMI above a specific number and the presence of at least one weight-related condition.

What to do if your plan does not cover Wegovy

If you have Original Medicare or a Medicare Advantage plan that does not cover Wegovy, you have several options. The first is to ask your doctor whether a different weight-loss medication might be covered — some plans cover phentermine or other older drugs that are less expensive.

The second is to contact Novo Nordisk, the manufacturer, about their patient information program. The company offers discounts for people without insurance coverage or with high out-of-pocket costs. You can reach them through their website or ask your doctor's office for the phone number. You will need to provide income information, and the program may reduce your monthly cost significantly.

A third option is to ask your doctor about switching to a different Medicare Advantage plan during the annual open enrollment period (October 15 to December 7 each year). If you know that Wegovy is important to your treatment plan, you can compare plans based on their formularies before you enroll. Keep in mind that switching plans also changes your doctors, hospitals, and prescription drug coverage, so weigh the full picture before deciding.

The difference between Original Medicare and Medicare Advantage coverage

Original Medicare is the federal program; it has the same rules nationwide and does not cover weight-loss drugs. Medicare Advantage plans are run by private insurance companies under contract with Medicare, and each company sets its own rules about which drugs to cover.

This means that two people with Medicare Advantage in the same city might have different coverage for Wegovy depending on which plan they chose. One plan might cover it with a $50 copay, while another might not cover it at all. If you are enrolled in a Medicare Advantage plan and Wegovy is important to you, it is worth checking your specific plan's formulary rather than assuming based on what a neighbor's plan covers.

Prior authorization and what your doctor needs to do

If your Medicare Advantage plan covers Wegovy, it almost certainly requires prior authorization — a process where your doctor submits documentation to the insurance company asking permission to prescribe the drug before you fill the prescription.

Your doctor's office typically handles this request, but you can speed it up by providing them with your insurance information and asking them to submit it as soon as possible. The insurance company usually responds within 3 to 5 business days. If they deny the request, your doctor can appeal, and you have the right to request a peer-to-peer review where your doctor speaks directly with the insurance company's medical director.

Common reasons for denial include: your BMI does not meet the plan's threshold, you do not have a documented weight-related condition, or you have not tried other weight-loss methods first. Ask your doctor what documentation the plan needs before submitting the request, so you can avoid delays.

Cost if you pay out of pocket

Wegovy costs between $900 and $1,350 per month at full retail price, depending on the dose and your pharmacy. This is a significant expense for most people on a fixed income.

If you do not have coverage through Medicare, the manufacturer's savings program can reduce this substantially. Novo Nordisk's program caps your monthly out-of-pocket cost at $250 for most people, though the exact amount depends on your income and insurance status. You can also ask your pharmacy whether they offer any discounts or whether a generic version of semaglutide (which may be less expensive) is available.

Frequently Asked Questions

Can I switch to a Medicare Advantage plan that covers Wegovy outside of open enrollment?

No, unless you have a may have access to life event such as losing your job, moving to a new state, or losing your current coverage. Open enrollment runs from October 15 to December 7 each year. If you do not have a may have access to event, you must wait until the next open enrollment period to switch plans.

If my doctor prescribes Wegovy, will Medicare automatically pay for it?

No. If you have Original Medicare, Medicare will not pay for it under any circumstances. If you have a Medicare Advantage plan, the plan will only pay if the drug is on your formulary and your doctor has received prior authorization. You should never assume coverage — always check with your plan first.

What is the difference between Wegovy and Ozempic?

Both contain semaglutide, but Ozempic is approved by the FDA to treat type 2 diabetes, while Wegovy is approved for weight loss. Medicare is more likely to cover Ozempic if you have diabetes, because it is treating a disease rather than weight loss alone. Ask your doctor whether Ozempic might be an option for you if you have diabetes and your plan does not cover Wegovy.

Can I appeal if my plan denies coverage for Wegovy?

Yes. You have the right to file a formal appeal with your Medicare Advantage plan within 60 days of the denial. Your doctor can also request a peer-to-peer review. If the plan denies your appeal, you can file a complaint with your state's insurance commissioner or contact Medicare directly at 1-800-MEDICARE.

Does Medicaid cover Wegovy?

Medicaid coverage varies by state. Some states cover Wegovy for people who meet certain criteria, while others do not cover it at all. Contact your state's Medicaid office or your Medicaid managed care plan to find out whether it is covered where you live.
