Medicare Part D coverage of Ozempic depends on your specific plan and whether you are taking it for diabetes or weight loss
Medicare Part D plans do cover Ozempic (semaglutide), but not all plans cover it the same way, and coverage rules changed significantly in 2024. If you take Ozempic for type 2 diabetes, most Part D plans will cover it — though you may pay a copay or coinsurance. If you take it for weight loss (off-label use), coverage is much less common and many plans exclude it entirely. Your actual out-of-pocket cost depends on which Part D plan you chose, what tier Ozempic sits on within that plan, and whether you have hit your deductible yet.
The key change: starting in 2024, Medicare can now negotiate drug prices directly with manufacturers. Ozempic and similar GLP-1 drugs were among the first drugs selected for negotiation, which means some plans may have lowered their costs. However, this does not mean Ozempic is now cheap or that every plan covers it equally. You need to check your own plan's formulary — the official list of drugs your plan covers — to know what you will actually pay.
Key Takeaways
- Most Medicare Part D plans cover Ozempic for type 2 diabetes, but coverage for weight loss is rare and many plans exclude it.
- Your out-of-pocket cost depends on your plan's formulary tier, your deductible status, and whether you meet the plan's prior authorization requirements.
- You can check your plan's coverage by calling the plan directly, visiting its website, or using the Medicare Plan Finder tool with your plan name and member ID.
- If your plan does not cover Ozempic or charges a high copay, you can switch to a different Part D plan during the annual open enrollment period (October 15 to December 7).
- Some manufacturers offer patient information programs that reduce the cost of Ozempic if you meet income requirements, even if your plan covers it.
How Part D formularies determine what you pay for Ozempic
Every Medicare Part D plan publishes a formulary — a list that places each drug into a tier, and your tier determines your copay or coinsurance. Ozempic typically sits on Tier 3 or Tier 4 (the higher tiers), which means you pay more than you would for a generic drug on Tier 1. Some plans place it on Tier 2. The exact copay or coinsurance amount varies by plan; one plan might charge $50 per month, another $150, and a third might charge 25 percent coinsurance (meaning you pay 25 percent of the drug's cost after your deductible).
Before your plan pays anything, you must meet your annual deductible — the amount you pay out of pocket before Part D coverage kicks in. In 2024, Part D deductibles range from $0 to $545, depending on the plan. Once you meet the deductible, you move into the copay phase, where you pay your tier copay and the plan pays the rest. If you reach a certain spending threshold (called the initial coverage limit), you enter the coverage gap, sometimes called the "donut hole," where you pay a higher percentage of the drug cost until you reach catastrophic coverage.
The formulary can also include a prior authorization requirement, which means your doctor must request permission from the plan before the pharmacy will fill your prescription. Some plans require this for Ozempic; others do not. If your plan requires it, your doctor's office typically handles the request, but it can add a few days to the process.
Checking your specific plan's coverage right now
The fastest way to know what your plan covers is to call the customer service number on the back of your Medicare card. Have your member ID ready and ask: "Does my plan cover Ozempic? What tier is it on? What is my copay? Does the plan require prior authorization?" Write down the answers. If the representative is unsure, ask them to check the formulary directly or send you a copy by mail or email.
You can also check online. Visit your plan's website (the name is on your card) and look for "Formulary" or "Drug List." Search for "semaglutide" or "Ozempic" — some formularies let you search by brand name, others by generic name. If you do not know your plan name, visit Medicare.gov, sign in with your account, and go to "My Health Plans" to see which plan you are enrolled in.
A third option is the Medicare Plan Finder tool at Medicare.gov. You can enter Ozempic and your zip code, and the tool will show you which plans in your area cover it and what the estimated cost would be. This tool is most useful if you are shopping for a new plan during open enrollment, but it can also show you current coverage if you enter your plan name.
Prior authorization and step therapy requirements
Some Part D plans require step therapy for Ozempic, which means your doctor must show that you tried a cheaper diabetes drug first and it did not work before the plan will cover Ozempic. This is most common for plans that cover Ozempic for diabetes but want to control costs. If your plan has a step therapy requirement and you have already tried other drugs, your doctor can submit documentation of that history along with the prior authorization request, and the plan may approve Ozempic without delay.
If your plan denies coverage or requires step therapy and you believe it is medically necessary, you have the right to appeal. Your doctor can submit an appeal on your behalf, explaining why Ozempic is the right choice for you. The plan must respond to an appeal within 72 hours for urgent cases. Many appeals succeed, especially if your doctor provides clinical reasoning.
Coverage for weight loss versus diabetes
Medicare Part D coverage of Ozempic for weight loss (not diabetes) is uncommon. Ozempic is approved by the FDA for type 2 diabetes, but doctors can prescribe it off-label for weight loss. Most Part D plans do not cover off-label uses, and many plans explicitly exclude GLP-1 drugs when prescribed for weight loss. If you are taking Ozempic for weight loss, check your formulary carefully — do not assume it is covered just because you have Part D.
If your plan does not cover Ozempic for weight loss, you have a few options. You can pay out of pocket (the cash price is typically $900 to $1,300 per month for a month's supply of pens). You can ask your doctor about other weight loss medications that your plan does cover. Or you can switch to a different Part D plan during open enrollment if another plan in your area covers GLP-1 drugs for weight loss — though this is rare.
Switching plans if your current plan does not cover Ozempic affordably
If your plan does not cover Ozempic, covers it only with a very high copay, or requires step therapy you do not want to go through, you can switch to a different Part D plan. The annual open enrollment period runs from October 15 to December 7 each year. During this window, you can drop your current plan and join a new one, effective January 1.
To find a plan that covers Ozempic at a lower cost, use the Medicare Plan Finder tool. Enter your zip code, your current medications (including Ozempic), and your pharmacy. The tool will show you all available plans ranked by estimated cost. Look at the total estimated annual cost for your medications, not just the copay for Ozempic, because switching plans affects all your drugs.
If you miss the open enrollment window, you can still switch plans if you have a may have access to life event — such as moving to a new state, losing other insurance, or a change in your income. If you believe your plan's denial of Ozempic coverage is unfair, you can also file a complaint with Medicare, though this does not may provide a change in coverage.
Manufacturer information programs and other cost-reduction options
Novo Nordisk, the manufacturer of Ozempic, offers a patient information program called the Novo Nordisk PASSport program. If your income is below a certain threshold (typically around 300 percent of the federal poverty level, though this varies), you may be able to get Ozempic for free or at a reduced cost through this program. You do not have to be uninsured to use it — you can use it even if you have Part D, and it can help cover your copay or coinsurance.
To check whether you may have access to, visit the program's website or call Novo Nordisk directly at 1-844-NOVO-777. You will need to provide proof of income and insurance status. If you may have access to, the program can send you vouchers or coupons that reduce your out-of-pocket cost at the pharmacy.
Some pharmacies also offer their own discount programs. GoodRx, SingleCare, and similar discount programs sometimes offer prices lower than your Part D copay, especially if you have a high deductible or are in the coverage gap. Before you pay your copay, ask your pharmacist whether a discount program would cost less. You cannot use both your Part D coverage and a discount program at the same time, so compare the two options.
What happens if Ozempic is not on your plan's formulary at all
If Ozempic is not listed on your plan's formulary, the plan will not cover it, and you will pay the full cash price at the pharmacy. However, before you accept this, ask your plan whether there is a similar drug that is covered. Some Part D plans cover other GLP-1 drugs like Trulicity (dulaglutide) or Victoza (liraglutide) instead of Ozempic. These drugs work similarly but may be on a lower tier or have a lower copay. Your doctor can discuss whether one of these alternatives would work for you.
If your plan covers a different GLP-1 drug but not Ozempic specifically, your doctor can request a formulary exception — a formal request to the plan to cover a drug that is not on the formulary. The plan will review the request and may approve it if your doctor explains why Ozempic is medically necessary and why the covered alternatives are not suitable. This process typically takes 5 to 10 business days.
Frequently Asked Questions
Will Medicare Part D cover Ozempic if I take it for weight loss?
Most Part D plans do not cover Ozempic for weight loss because it is an off-label use. Some plans explicitly exclude GLP-1 drugs when prescribed for weight loss. Check your plan's formulary to be sure, but assume it is not covered unless your plan's documentation says otherwise. If it is not covered, you can pay out of pocket or ask your doctor about weight loss medications your plan does cover.
What is the difference between Ozempic and Wegovy?
Ozempic and Wegovy contain the same active ingredient (semaglutide) but are marketed for different uses. Ozempic is approved for type 2 diabetes; Wegovy is approved for weight loss. Medicare Part D typically covers Ozempic for diabetes but not Wegovy. However, doctors can prescribe either drug off-label, and coverage depends on your plan and the reason your doctor prescribes it.
Can I appeal if my plan denies coverage of Ozempic?
Yes. If your plan denies coverage or requires step therapy, your doctor can submit an appeal explaining why Ozempic is medically necessary for you. The plan must respond within 72 hours for urgent cases. Many appeals succeed, especially if your doctor provides clinical evidence that other drugs have not worked or are not appropriate.
What should I do if my copay for Ozempic is too high?
First, check whether the manufacturer's patient information program (Novo Nordisk PASSport) can reduce your cost. Second, compare your copay to discount programs like GoodRx or SingleCare — sometimes these are cheaper than your Part D copay. Third, if you are in open enrollment, shop for a different Part D plan that covers Ozempic at a lower tier. If none of these work, talk to your doctor about alternative diabetes medications your plan covers at a lower cost.
How do I know if my plan requires prior authorization for Ozempic?
Call your plan's customer service number (on your Medicare card) and ask directly. You can also check your plan's formulary online — it usually notes which drugs require prior authorization. If your plan requires it, your doctor's office can submit the request, and the plan typically responds within 3 to 5 business days.
