Does Humana Cover Mounjaro?
The verdict
Conditional on most plans
Humana covers Mounjaro for type 2 diabetes under Medicare Part D and Medicaid with prior authorization. Mounjaro is not covered for weight loss under any Humana line. Critically, Mounjaro is NOT included in the 2026 Medicare GLP-1 Bridge — which Humana itself administers — because the Bridge covers only weight-loss-approved products (Wegovy, Foundayo, Zepbound KwikPen). For weight loss, the same molecule (tirzepatide) is Zepbound, with separate coverage.
Coverage is set by your specific plan and formulary. This is a research summary — always confirm with Humana using your member ID.
Key facts
The 2026 Medicare GLP-1 Bridge ($50/month copay, administered by Humana) covers Wegovy, Foundayo, and the Zepbound KwikPen only — Mounjaro is excluded because it is a diabetes drug, not a weight-loss drug.

The 2026 Part D out-of-pocket cap is $2,100. Most Humana Part D enrollees taking Mounjaro continuously for diabetes reach the cap within 2-3 months and pay $0 for the rest of the year.

The IRA-negotiated Medicare MFN price for Mounjaro (tirzepatide) is $245/month, effective mid-2026 for Medicare enrollees.

Medicare vs. commercial coverage
Whether Humana covers Mounjaro depends heavily on which kind of plan you hold. They follow completely different rules — here's each one, side by side.
Medicare
Part D & Advantage plans
Humana Medicare Part D and Medicare Advantage plans cover Mounjaro for type 2 diabetes only — not weight loss — at a specialty or non-preferred tier, with prior authorization. The 2026 Part D out-of-pocket cap is $2,100; most continuous Mounjaro users for diabetes reach it within 2-3 months, then pay $0 for the rest of the year. The IRA-negotiated Medicare MFN price of $245/month begins mid-2026. Mounjaro is NOT included in the 2026 Medicare GLP-1 Bridge ($50/month, July 1, 2026 – December 31, 2027). Although Humana is CMS's selected central processor for administering the Bridge, the Bridge explicitly covers weight-loss-approved products only (all Wegovy formulations, Foundayo, and the Zepbound KwikPen). Mounjaro is excluded because it is a diabetes drug. The Lilly savings card is not usable by Medicare or Medicare Advantage beneficiaries.
Commercial / Employer
Group & marketplace plans
Humana has a limited commercial and employer-sponsored book of business. Where commercial coverage is offered, Mounjaro is covered for type 2 diabetes with prior authorization; weight-loss use is excluded. ACA/Individual: Humana has a limited ACA marketplace presence; Mounjaro is covered for T2D with PA where offered, and weight-loss GLP-1s are commonly excluded. Medicaid: Humana Medicaid managed-care plans cover Mounjaro for T2D with prior authorization and nominal cost-share per state PDL. Weight-loss GLP-1 coverage is not available under Humana Medicaid. The Lilly savings card is not available to Medicaid beneficiaries.

Your cost, three ways
What Mounjaro actually costs you swings enormously depending on how it's covered. Here's the realistic range.
Paying cash
Approximately $1,300–$1,560/month retail (WAC ~$1,080). The Lilly savings card is not available to Medicare or Medicaid beneficiaries.
List price with no coverage — before any manufacturer savings card.
With coverage
Medicare Part D: 25% coinsurance after deductible until the $2,100 out-of-pocket cap; most continuous users reach the cap within 2-3 months and pay $0 thereafter. MFN price of $245/month begins mid-2026 for Medicare. Medicaid: nominal cost-share per state PDL.
Typical monthly copay once prior authorization is approved.
Bridge program
The 2026 Medicare GLP-1 Bridge ($50/month) covers weight-loss-approved products only and does not apply to Mounjaro.
Reduced copay through the assistance program, where eligible.
All figures are estimates; actual cost-share varies by plan and pharmacy. Confirm with your Humana plan's formulary or member services. The Lilly savings card applies only to commercially insured patients and expires 12/31/2026.
Check YOUR exact coverage in 3 steps
General answers only get you so far. Here's how to confirm your own plan's decision in a few minutes.
- 1
Check the Humana formulary for your specific plan
Visit Humana.com and use the drug finder tool for your specific Medicare Part D, Medicare Advantage, or Medicaid plan. Enter 'Mounjaro' or 'tirzepatide' and confirm it is listed for diabetes (ICD-10 E11.x) on your plan's drug list. Note the tier and whether prior authorization is required.
- 2
Work with your prescriber on the PA submission
Your prescriber needs to document your confirmed T2D diagnosis, A1c of 6.5% or higher, and prior use of metformin or a documented contraindication. Humana's Part D coverage determination process requires this evidence. Submit the PA through your prescriber's office; allow up to 72 hours for standard review or 24 hours for urgent requests.
- 3
Call Humana member services to confirm cost and Bridge eligibility
Call the number on the back of your Humana card. Ask: Is Mounjaro covered for type 2 diabetes on my plan? What is my out-of-pocket cost-share? Am I enrolled in a plan that is part of the 2026 Medicare GLP-1 Bridge, and does the Bridge cover Mounjaro? (Answer to the last question: No — the Bridge excludes Mounjaro.)
Options if Humana won't cover Mounjaro
A denial isn't the end of the road. These are the paths people commonly explore next — discuss any of them with your prescriber.
Ozempic (semaglutide)
FDA-approved for type 2 diabetes. Often covered at a preferred or non-preferred brand tier on Humana Part D plans with prior authorization.
Trulicity (dulaglutide)
FDA-approved for T2D. GLP-1 alternative frequently at preferred tier on Humana formularies; lower list price than Mounjaro.
Jardiance (empagliflozin)
SGLT2 inhibitor approved for T2D with cardiovascular benefits. Often on preferred tiers for Humana Medicare and Medicaid plans.
Zepbound (tirzepatide) — weight loss only
Same molecule as Mounjaro (tirzepatide) but FDA-approved for chronic weight management and obstructive sleep apnea. NOT diabetes coverage. Zepbound is included in the 2026 Medicare GLP-1 Bridge ($50/month) for weight-loss indication; Mounjaro is not. Coverage requires a separate weight-loss indication approval.
These options are listed for information only — your own clinician decides what is appropriate for you.
Frequently Asked Questions
No. The 2026 Medicare GLP-1 Bridge — which Humana administers as the CMS-selected central processor — covers weight-loss-approved products only: all Wegovy formulations, Foundayo, and the Zepbound KwikPen. Mounjaro is excluded from the Bridge because it is FDA-approved for type 2 diabetes, not weight loss. Medicare covers Mounjaro under standard Part D for diabetes only, with prior authorization and specialty-tier cost-share, subject to the $2,100 annual OOP cap.
No. Humana does not cover Mounjaro for weight loss under any line of business — Medicare Part D, Medicare Advantage, Medicaid, or commercial. Mounjaro is FDA-approved for type 2 diabetes only. Off-label weight-loss requests coded with obesity diagnoses are denied. For weight loss, the same active ingredient (tirzepatide) is available as Zepbound, which is FDA-approved for chronic weight management. Zepbound has separate and often-excluded coverage from Mounjaro.
Under the 2026 Medicare Part D redesign, you pay 25% coinsurance after your deductible until you hit the $2,100 annual out-of-pocket cap. Most continuous Mounjaro users for diabetes reach the cap within 2-3 months and pay $0 for the remainder of the year. Starting mid-2026, the IRA-negotiated Medicare MFN price of $245/month takes effect. The Lilly savings card is not available to Medicare or Medicare Advantage beneficiaries.
Humana's Part D prior authorization process requires a confirmed type 2 diabetes diagnosis (ICD-10 E11.x), A1c of 6.5% or greater, and documented trial or failure of metformin (and often one additional oral agent). Patient must be 18 or older. Quantity limit is typically 4 pens per 28 days. Your prescriber submits the PA on your behalf; verify the specific criteria and process on Humana's coverage determination portal.
Only if you have a Humana commercial plan (employer-sponsored), not Medicare or Medicaid. The Lilly Mounjaro Savings Card is explicitly unavailable to Medicare Part D, Medicare Advantage, Medicaid, Medicare Supplement/Medigap, DoD, VA, and TRICARE beneficiaries. Commercially insured Humana members with Mounjaro coverage may pay as little as $25/month; without coverage, $499/month (up to 13 fills, expires 12/31/2026).
