Does insurance cover Zepbound? Sometimes. It depends on your plan and why Zepbound is prescribed. Only 19% of employers with 200 or more workers covered GLP-1 drugs for weight loss in 2025, according to KFF.[1] Some plans that exclude weight-loss drugs still cover Zepbound for obstructive sleep apnea, which they treat as a separate medical use.[4][5] When a plan covers Zepbound, prior authorization is almost always required.
Prices and program terms checked October 2026. They change often; confirm with the manufacturer or your plan.
Zepbound is tirzepatide, also sold as Mounjaro for diabetes. See our tirzepatide profile.
Coverage by reason for treatment
| Reason prescribed | Is Zepbound approved for it? | How insurers usually treat it |
|---|---|---|
| Weight management (obesity, or overweight plus a related condition) | Yes[2] | Covered only if the plan includes weight-loss drugs; prior authorization required[1][5] |
| Moderate to severe obstructive sleep apnea with obesity | Yes, since December 2024[3] | Often covered as a separate benefit with a sleep study and prior authorization[4][5] |
| Type 2 diabetes | No; Mounjaro is the tirzepatide brand for diabetes[2] | Plans cover Mounjaro instead |
| Lowering heart attack or stroke risk | Not a Zepbound indication[2] | Not a covered Zepbound use on that basis |
Weight loss: the employer decides
For weight management, your employer or plan sponsor decides whether weight-loss drugs are a covered benefit at all. KFF’s 2025 survey found coverage rises with employer size: 16% of firms with 200 to 999 workers, 30% with 1,000 to 4,999 and 43% with 5,000 or more.[1] About a third of covering firms require a dietitian, case manager or lifestyle program.[1]
Some insurers have dropped coverage for cost reasons. Blue Cross Blue Shield of Massachusetts, for example, ended GLP-1 coverage except for type 2 diabetes at plan renewals starting January 1, 2026.[8]
Sleep apnea: a separate path
Zepbound gained approval for moderate to severe obstructive sleep apnea (OSA) in adults with obesity on December 20, 2024, based on the SURMOUNT-OSA trials in 469 adults.[3][11]
Because OSA is a medical diagnosis, some plans that exclude weight-loss drugs still cover Zepbound for it. UnitedHealthcare’s OSA-only policy states that weight-loss drugs are “typically a benefit exclusion” but allows Zepbound for OSA.[4] Typical OSA criteria include:[4][5]
- Age 18 or older and a BMI of 30 or more.
- A sleep study showing an apnea-hypopnea index (breathing pauses per hour) of 15 or more.
- No central sleep apnea.
- For some plans, continued symptoms despite CPAP or a reason CPAP is not suitable, and a sleep specialist involved.
See Zepbound for sleep apnea for the clinical side.
What prior authorization usually requires
For weight management, most policies mirror the label: a BMI of 30 or more, or 27 or more with at least one weight-related condition such as high blood pressure, type 2 diabetes, high cholesterol or sleep apnea.[5] Cigna’s 2026 policy, for example, also requires at least 3 months of diet and behavior changes first, approves an initial 8 months, and renews only if you have lost at least 5% of your starting weight.[5] Some plans set stricter rules, such as a BMI of 35. See does Cigna cover Zepbound? and our other insurer guides for specifics.
CVS Caremark: excluded in 2025, back in October 2026
CVS Caremark manages drug benefits for many employers. On July 1, 2025, it took a formulary action to prefer Wegovy and remove Zepbound from its main commercial template formularies.[6] On May 28, 2026, Caremark said it would add Zepbound back as “an additional preferred option” on October 1, 2026, for plan sponsors that choose to cover these drugs.[7] Lilly’s savings page now notes that coverage has been restored on select Caremark formularies.[10] Whether your own plan follows that template is up to your employer. See does Aetna cover Zepbound?
Medicare and Medicaid
Medicare Part D has long excluded drugs used for weight loss. Since July 1, 2026, the temporary Medicare GLP-1 Bridge covers the Zepbound KwikPen for $50 a month for eligible members, through December 31, 2027. Sleep apnea and diabetes prescriptions go through the regular Part D plan.[9] Details: does Medicare cover Zepbound? Medicaid coverage varies by state.
What Zepbound costs when insurance covers it
Coverage does not always mean a low price. Your share depends on the drug’s tier, your deductible and whether you pay a flat copay or a percentage (coinsurance). Lilly’s savings card fills the gap for commercially insured people whose plan covers the single-dose pen: you may pay as little as $25 for a 1-, 2- or 3-month fill, with Lilly paying up to $100, $200 or $300 per fill and $1,300 a year.[10]
That means a person with a $1,000 deductible could still pay several hundred dollars for the first fill of the year, and someone with high coinsurance may hit the $1,300 yearly cap before December. Asking your plan for your exact cost-share, and asking for a 3-month fill if allowed, helps you plan.[10]
How to check your own coverage
- Search your plan’s formulary (the covered-drug list) in your member portal or app. Look for Zepbound, its tier and the letters “PA” (prior authorization) or “QL” (quantity limit).
- Call the member services number on your insurance card. Ask whether weight-loss drugs are a covered benefit, whether Zepbound is covered for sleep apnea, and what the prior authorization criteria are.
- Check your employer’s benefits summary. A plan can list Zepbound on its formulary but still exclude weight-loss drugs as a benefit.
- Use Lilly’s coverage checker on the Zepbound savings page for an estimate.[10]
- Ask your prescriber’s office to submit prior authorization with BMI, related conditions, sleep study results and diet history.
If you are denied
- Ask why. A benefit exclusion (the plan does not cover weight-loss drugs at all) usually cannot be appealed, as Blue Cross Blue Shield of Massachusetts states for its exclusion.[8] A clinical denial (criteria not met) usually can be.
- Appeal with documentation if you meet the criteria but paperwork was missing.
- Ask about a formulary exception if your plan prefers a different drug.
Paying when insurance says no
If your commercial plan excludes Zepbound, the savings card lowers the single-dose pen to as low as $499 a month or the KwikPen to $299 to $449.[10] Without any insurance, LillyDirect sells vials and KwikPens at $299 to $449 a month.[12] See Zepbound cost without insurance and the Zepbound savings card guide.
