Cost by How You Pay
What a month of Zepbound runs, depending on whether you pay cash, use LillyDirect, or have coverage. Prices are approximate and vary by dose, pharmacy, and plan.
| How you pay | Typical monthly cost |
|---|---|
| List (cash) price | ~$1,060/mo |
| LillyDirect self-pay vials | ~$349 to $499/mo |
| Covered copay (commercial) | often $25 to $250/mo |
| Medicare Part D (OSA indication) | tier cost sharing to $2,000/yr cap |
What most people actually pay: if you have commercial coverage, your copay after the copay card; if you do not, the LillyDirect self-pay vial price, roughly $349 to $499 a month.
Coverage Depends on Why You Take It
Zepbound is FDA-approved for two uses, and coverage differs a lot between them. Getting the right indication on the prescription can be the difference between a covered copay and paying the full list price.
| FDA-approved use | How coverage tends to go |
|---|---|
| Chronic weight management (obesity) | Harder. Many employer plans exclude weight-loss drugs, and Medicare Part D does not cover it for weight loss. |
| Obstructive sleep apnea (OSA) in adults with obesity, 2024 | Often easier. More plans cover the OSA diagnosis, and some Medicare Part D plans may cover it depending on the plan. |

Pay cash through LillyDirect if you have no coverage

Ask your prescriber about the sleep apnea indication
If you have obstructive sleep apnea with obesity, ask your prescriber to submit for the OSA diagnosis. Plans cover the OSA indication more often than weight loss alone. See help paying for medication for other assistance options.

Does insurance cover Zepbound?
It depends on your plan and the reason you are taking it. Many employer plans exclude weight-loss drugs, so coverage for weight management alone can be hard to get. Zepbound is also FDA-approved for obstructive sleep apnea (OSA) in adults with obesity, and coverage is often easier for the OSA indication. When a plan does cover it, a commercial copay card can lower your copay. See our guide on whether insurance covers Zepbound.
Does Medicare cover Zepbound?
Medicare Part D does not cover Zepbound for weight loss. It may cover the obstructive sleep apnea (OSA) indication depending on the specific plan. When it is covered, you pay your plan's tier cost sharing, and in 2026 your total yearly out-of-pocket for covered Part D drugs is capped at $2,000. The commercial copay card cannot be used with Medicare or Medicaid.
How can I lower the cost of Zepbound?
If you have commercial insurance that covers Zepbound, use Eli Lilly's copay card to lower your copay. If you do not have coverage, Eli Lilly's LillyDirect self-pay vials (roughly $349 to $499 a month) are usually the cheapest route. For the sleep apnea indication, ask your prescriber to submit for the OSA diagnosis, which plans cover more often than weight loss alone. If a pharmacy or specialty bill still looks wrong, CareRoute Bill Defense can review and negotiate it, with no fee unless we save you money.
