GLP-1 drugs such as Ozempic, Wegovy, and Zepbound are expensive, and whether your insurance helps pay depends on three things: which drug you are prescribed, why you are taking it, and what kind of coverage you have. This guide walks through each type of coverage and the steps that give you the best shot at an approval.
Start with the right drug for the right reason
Health plans look closely at the diagnosis on your prescription. The same active ingredient can be covered for one use and denied for another.
- Ozempic is FDA-approved for type 2 diabetes. If you have diabetes, most plans cover it or a similar drug, sometimes with prior authorization. If you do not have diabetes, plans usually deny Ozempic because weight loss is not an approved use for it.
- Wegovy and Zepbound are approved for chronic weight management. If your plan covers weight-loss medications at all, these are the drugs it is most likely to cover for that purpose.
Before anything else, see a doctor to decide whether one of these medicines is medically appropriate for you. A doctor who treats obesity regularly will also know what insurers tend to ask for.
Employer and Marketplace (ACA) plans
Check whether the plan covers weight-loss drugs at all
Many employer and individual plans exclude drugs used only for weight loss. Others cover them with restrictions. Large employers that self-fund their plans make this decision themselves, so two people with the same insurance company can have very different coverage. To find out where you stand:
- Look up the drug in your plan's formulary, the list of covered drugs, usually on the member portal.
- Note any flags next to the drug, such as PA (prior authorization), ST (step therapy), or QL (quantity limit).
- Call the member services number on your ID card and ask directly whether weight-loss medications are excluded.
- If you are shopping for a new plan, check the formulary before you enroll. We can help you compare.
Prior authorization: what plans usually want to see
When a plan does cover these drugs, your doctor will almost always need to submit a prior authorization request. Criteria vary by plan, but they commonly track the FDA label: a body mass index (BMI) of 30 or higher, or 27 or higher with a weight-related condition such as high blood pressure, high cholesterol, or sleep apnea. Plans may also ask for:
- Documentation of a diet, exercise, or lifestyle program you have tried or are in now
- Records of other weight-loss medications you have already tried (step therapy)
- Your starting weight and BMI, with dates
- Progress after a few months, often a minimum percentage of weight lost, before refills are approved
The most common reason for a denial is missing paperwork. Ask your doctor's office to send chart notes that match the plan's published criteria line by line. Many insurers post their criteria online, so search your insurer's name plus the drug name and "prior authorization."
If you are denied, appeal
A denial is not always the final word. Under the Affordable Care Act, most plans must offer an internal appeal and, if that fails, an external review by an independent reviewer.
- Read the denial letter. It must explain the reason and how to appeal.
- Fix the gap. If the plan said a criterion was not met, have your doctor send records that show it was.
- File the internal appeal. You generally have 180 days from the denial notice. For a drug you have not received yet, the plan generally must decide within 30 days. Urgent cases move faster.
- Request an external review if the internal appeal is denied. The instructions will be in the final denial letter.
Your doctor can also ask for a formulary exception if the plan covers weight-loss drugs but not the specific one you need. If the plan excludes weight-loss drugs entirely, an appeal is less likely to succeed. In that case, some people ask their employer's HR or benefits team whether the exclusion is under review.

Medicare
Regular Part D coverage
By law, Medicare drug plans cannot cover drugs used only for weight loss. Part D plans can cover GLP-1 drugs for other approved medical uses. According to Medicare, your plan may cover a GLP-1 if you have type 2 diabetes, moderate to severe obstructive sleep apnea, or certain types of fatty liver disease. A plan may also cover Wegovy to lower the risk of heart attack and stroke in people with established cardiovascular disease. Your plan will usually require prior authorization, and what you pay counts toward your Part D deductible and yearly out-of-pocket cap.
The Medicare GLP-1 Bridge
For people who want a GLP-1 for weight management, Medicare runs a temporary program called the Medicare GLP-1 Bridge from July 1, 2026 through December 31, 2027. Key points:
- Cost: a $50 copay for a one-month supply.
- Drugs: Foundayo (tablet), Wegovy (injection or tablet), and Zepbound (KwikPen only).
- Who qualifies: people 18 or older with Medicare drug coverage who meet a BMI threshold: 35 or higher; 30 or higher with certain heart or kidney conditions; or 27 or higher with prediabetes, a prior heart attack or stroke, or symptomatic peripheral artery disease. Your provider must certify that you are also in a diet and exercise program.
- Who does not: people already getting a GLP-1 through their Part D plan, and people with type 2 diabetes, moderate to severe sleep apnea, or fatty liver disease, since their Part D plan may cover a GLP-1 instead.
- Limits: the $50 does not count toward your Part D deductible or out-of-pocket cap, Extra Help does not reduce it, and it cannot be paid through the Medicare Prescription Payment Plan.
Medicare, not your drug plan, handles the prior authorization. For details, see our GLP-1 Bridge series:

Medicare appeals
If your Part D plan denies a GLP-1 you need for a covered condition, ask for a coverage determination or exception. The plan must decide within 72 hours of getting your doctor's supporting statement, or 24 hours if your doctor says waiting could seriously harm your health. If it still says no, you have 65 days from the notice to request a redetermination, the first of five appeal levels.
Manufacturer savings and self-pay prices
If your plan will not pay, or your share is high, the drug makers offer two kinds of help. Terms change often, so confirm on the manufacturer's site before you fill.
| Situation | What is available (as of October 2026) |
|---|---|
| Commercial insurance covers the drug | Savings cards for Wegovy and Zepbound can lower your copay to as little as $25, subject to monthly and yearly maximums. |
| Commercial insurance does not cover it, or no insurance | Self-pay pricing direct from the manufacturer. Novo Nordisk lists the Wegovy pill from $149 a month for the lowest dose and Wegovy pens at $349 a month for standard doses. Lilly lists Zepbound from $299 a month for the 2.5 mg dose through LillyDirect, with higher doses costing more. |
| Medicare, Medicaid, TRICARE, or VA | Copay savings cards do not apply. Self-pay prices may still be an option, and eligible Medicare enrollees can use the $50 GLP-1 Bridge. |
Money you spend on a self-pay price generally does not count toward your health plan's deductible or out-of-pocket maximum. Be cautious with compounded versions sold online. They are not FDA-approved, and the GLP-1 Bridge does not cover them.
Quick checklist
- Confirm the diagnosis and drug match what your plan covers.
- Check the formulary and the prior authorization criteria.
- Give your doctor everything the criteria ask for, including dated weight and BMI records.
- Appeal a denial, in writing, before the deadline.
- On Medicare, check whether your Part D plan covers your condition or whether you qualify for the GLP-1 Bridge.
- Compare manufacturer self-pay prices if insurance will not help.
