Does Medicare cover Zepbound in Ohio?

What Zepbound is used for

Zepbound is tirzepatide, a once-weekly injection that acts on two gut hormones (GLP-1 and GIP). Its FDA label includes chronic weight management in adults with obesity, or with overweight and a weight-related health problem, together with diet and exercise; and, since December 20, 2024, moderate to severe obstructive sleep apnea in adults with obesity. Mounjaro is the same medicine, approved for type 2 diabetes.

This page explains Medicare coverage only. Questions about whether Zepbound is right for you belong with your prescriber.

Which part of Medicare covers Zepbound

Zepbound is self-injected, so any Medicare coverage runs through Part D, in one of two ways:

• Your Part D plan can cover Zepbound for a medically accepted use that isn't weight loss alone, such as obstructive sleep apnea, if Zepbound is on its formulary. Expect prior authorization.
• The Medicare GLP-1 Bridge covers the Zepbound KwikPen for weight management when you meet CMS's criteria, outside your plan's formulary.

Federal law (Social Security Act §1860D-2(e)) excludes drugs used for weight loss from Part D, which is why a plan can't cover Zepbound for weight loss on its own.

How the Medicare GLP-1 Bridge works for Zepbound

• Dates: coverage started July 1, 2026, and CMS extended it through December 31, 2027. CMS hasn't announced coverage after that.
• Which Zepbound: only the Zepbound KwikPen. Medicare.gov says the Bridge doesn't cover single-dose Zepbound vials or pens. It also covers Wegovy and Foundayo.
• Who qualifies: people with Part D, 18 or older, with a BMI of 35 or more; or 30 or more with diastolic heart failure, uncontrolled high blood pressure or stage 3a or later kidney disease; or 27 or more with prediabetes, a past heart attack or stroke, or peripheral artery disease with symptoms.
• Who doesn't: people who already get a GLP-1 through their Part D plan, and people with type 2 diabetes, moderate to severe sleep apnea or fatty liver disease. For those conditions, your Part D plan might cover a GLP-1 instead.
• How: your prescriber sends the prescription and completes the prior authorization, certifying you're in a diet and exercise program. You pay a flat monthly copay set by CMS, shown on Medicare.gov.
• Limits: the Bridge copay doesn't count toward your Part D deductible or the $2,400 cap, and Extra Help and the Medicare Prescription Payment Plan can't be used for it.

Is Zepbound on Medicare's negotiated-price list?

Zepbound is not among the drugs CMS has selected for the Medicare Drug Price Negotiation Program so far: the 10 drugs with negotiated prices since January 1, 2026, the 15 with negotiated prices starting January 1, 2027, and the 15 CMS selected on January 27, 2026, for prices that take effect in 2028.

What you pay for Zepbound in 2027: the out-of-pocket cap

Your cost for Zepbound depends on your plan: its deductible, the tier it puts the drug on, and whether you use a preferred pharmacy. This site doesn't list plan costs; your plan's formulary and Evidence of Coverage do. What Medicare sets for everyone with Part D is the limit:

• 2027 out-of-pocket cap: $2,400 (it was $2,100 in 2026). Once what you pay for covered Part D drugs (deductible, copays and coinsurance) reaches the cap, you pay nothing more for covered Part D drugs for the rest of 2027.
• The maximum Part D deductible for 2027 is $700. No plan can set a higher deductible.
• Only covered drugs count. If your plan doesn't cover Zepbound and you pay cash, or you use a discount card instead of your plan, that spending doesn't count toward the cap.

These cost rules apply when your Part D plan covers Zepbound, for example for sleep apnea. Zepbound through the GLP-1 Bridge has its own copay, which doesn't count toward the cap.

Spreading the cost: the Medicare Prescription Payment Plan

The Medicare Prescription Payment Plan lets you pay your Part D drug costs in monthly bills from your plan across the calendar year instead of all at once at the pharmacy. Medicare.gov says there's no cost to participate, but it doesn't lower your drug costs; it only changes when you pay. It helps most when your costs are high early in the year. To join, call your plan or use its website. More in What is the Medicare Prescription Payment Plan?

Extra Help with Zepbound

Extra Help (the Low-Income Subsidy) is a federal program that lowers Part D premiums, deductibles and copays. For 2027, CMS caps Extra Help copays for covered drugs at $5.80 for a generic and $14.40 for a brand-name drug, and some people with full Medicaid pay less. You get Extra Help automatically if you have full Ohio Medicaid, one of Ohio's Medicare Premium Assistance Programs (QMB, SLMB or QI-1) or SSI. Otherwise, apply through Social Security at ssa.gov/extrahelp or 1-800-772-1213 (TTY 1-800-325-0778). See Extra Help in Ohio.

Getting Zepbound covered in Ohio

Ohio is a Part D region of its own (region 14), so each standalone Part D plan sold in Ohio is offered in all 88 counties. For 2027, Ohio has 9 standalone Part D plans from 5 companies. Every county also has Medicare Advantage plans open to everyone, from 22 in Scioto County to 68 in Summit County, according to CMS data. Each plan has its own formulary, so one plan's coverage of Zepbound tells you nothing about another's. Check your county's numbers on Ohio counties.

If your Medicare Advantage plan is ending in 2027, your plan sends a non-renewal letter, and you have a special enrollment period that runs through February 28, 2027. To keep Zepbound covered without a gap, choose a new plan with drug coverage by December 31, 2026. See Ohio plans ending in 2027.

If you have both Medicare and Ohio Medicaid, Medicare drug coverage (Part D), not Ohio Medicaid, pays for Part D drugs like Zepbound, and you qualify for Extra Help automatically. If you're in MyCare Ohio and chose the same MyCare plan for your Medicare, that plan also provides your Part D coverage. See Ohio Medicaid and Medicare and MyCare Ohio.

Ohio public retirees: STRS Ohio and SERS retirees get Part D through the system's group plan, and joining a separate Part D or Medicare Advantage plan can end that coverage, so check with your system before you change anything. OPERS, OP&F and HPRS retirees choose individual plans through the system's marketplace. See Ohio public retirement systems and Medicare.

How to check whether a plan covers Zepbound

1. Write down the exact drug. Name, strength and how often you take it. A plan can cover one form of Zepbound and not another.
2. Look it up in each plan's formulary. Enter your drugs and ZIP code on PlanMatch or Medicare.gov's Plan Finder to see which plans list Zepbound and any rules.
3. Read the rules next to the drug. Prior authorization, step therapy or quantity limits mean your prescriber may need to send the plan information before it pays.
4. Check your 2027 notice. Your plan's Annual Notice of Change says whether Zepbound stays on the formulary next year. Open Enrollment runs October 15 to December 7, 2026, for coverage starting January 1, 2027.
5. Get help if you want it. You can request a call from a licensed insurance agent, who can compare plans from the companies they work with, or call 1-800-MEDICARE (1-800-633-4227, TTY 1-877-486-2048) for information on all of your options.

If your plan doesn't cover Zepbound, you or your prescriber can ask for a coverage determination or a formulary exception. Once the plan has your prescriber's supporting statement, it generally must decide within 72 hours, or 24 hours if your prescriber says waiting could seriously harm your health. New members can usually get a one-time transition supply of a drug they were already taking while they ask for an exception or switch. See How do I appeal a Medicare denial in Ohio?
