Does Cigna Cover Mounjaro?
The verdict
Conditional on most plans
Cigna (Express Scripts/Evernorth) covers Mounjaro for type 2 diabetes as a non-preferred specialty drug at Tier 4/5 with 25–33% coinsurance, prior authorization, and step therapy (metformin plus one additional agent). Cigna does not cover Mounjaro for weight loss under any line of business. The weight-loss tirzepatide product is Zepbound, with separate and often more restricted coverage. The specialty-tier coinsurance is the highest cost exposure in the major-insurer cluster — verify plan-specific terms.

Key facts
Cigna places Mounjaro at a non-preferred specialty Tier 4/5 via Express Scripts — 25–33% coinsurance, versus a flat preferred-brand copay at carriers like Aetna (CVS Caremark Tier 2).
Express Scripts/Evernorth Formulary, 2025
Express Scripts step-therapy for Mounjaro requires metformin plus one additional agent (sulfonylurea, SGLT2 inhibitor, or a preferred GLP-1). Missing documented step therapy is the leading cause of PA denial.
Express Scripts Prior Authorization Criteria, Mounjaro (tirzepatide), 2025
The 2026 Medicare Part D out-of-pocket cap is $2,100. Most Mounjaro users for diabetes who stay on therapy continuously reach this cap within 2–3 months, then pay $0 for the rest of the year.

Medicare vs. commercial coverage
Whether Cigna 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
Cigna Medicare Advantage and Part D plans cover Mounjaro for type 2 diabetes only — not weight loss — with prior authorization via Express Scripts. Coverage sits at a specialty tier with 25–33% coinsurance. The 2026 Part D out-of-pocket cap is $2,100; most continuous Mounjaro users for diabetes reach it within 2–3 months and pay $0 for the remainder 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), which covers weight-loss-approved products only. The Lilly savings card is not usable by Medicare or Medicaid beneficiaries.
Commercial / Employer
Group & marketplace plans
Cigna commercial and employer-sponsored plans: Mounjaro is a non-preferred specialty drug at Tier 4/5 via Express Scripts (Evernorth), with prior authorization (confirmed T2D diagnosis, A1c 6.5% or higher, step therapy). Step therapy requires a documented trial of metformin plus one additional agent — which may include a sulfonylurea, SGLT2 inhibitor, or a preferred GLP-1 such as Ozempic or Trulicity. Not covered for off-label weight loss under any plan design. ACA/Individual: limited Cigna ACA presence; Mounjaro covered for T2D with PA; weight-loss GLP-1s commonly excluded. Medicaid: limited Cigna Medicaid footprint; covered for T2D with PA where offered. Lilly savings card: $25/month with commercial coverage; $499/month without (max $647/month, up to 13 fills, expires 12/31/2026). Not available to Medicare or Medicaid beneficiaries.

Meet all 5 and you have a documented case for approval. Missing any one is the most common reason requests are denied.
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). Lilly savings card: $499/month for commercially insured without coverage (max $647/month, up to 13 fills, expires 12/31/2026). Not available to Medicare or Medicaid beneficiaries.
List price with no coverage — before any manufacturer savings card.
With coverage
Non-preferred specialty Tier 4/5 coinsurance of 25–33%. On the ~$1,080–$1,560 monthly cost, that can translate to roughly $270–$515/month before the plan deductible or OOP maximum — verify your plan-specific coinsurance terms. Commercially insured with Mounjaro coverage may pay as little as $25/month via the Lilly savings card (expires 12/31/2026). Medicare Part D: 25–33% coinsurance until the $2,100 OOP cap 2026; MFN $245/month mid-2026.
Typical monthly copay once prior authorization is approved.
Bridge program
The 2026 Medicare GLP-1 Bridge ($50/month) covers weight-loss-approved products only; Mounjaro is not included.
Reduced copay through the assistance program, where eligible.
All figures are estimates based on published tier structure and WAC. The 25–33% specialty coinsurance is a range — confirm exact cost-share on the Cigna drug lookup tool or Express Scripts formulary. The Lilly savings card expires 12/31/2026 and is not available to Medicare, Medicaid, or government-program beneficiaries.
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 your plan's specialty-tier coinsurance terms on myCigna
Log in to myCigna.com and use the drug cost estimator to look up Mounjaro (tirzepatide) for your specific plan. Confirm whether your plan places it on Tier 4 or Tier 5 and what the coinsurance percentage is. The 25–33% range is based on Express Scripts' published structure, but plan-specific deductibles and OOP maximums materially affect your actual cost.
- 2
Have your prescriber submit the Express Scripts step-therapy prior authorization
Your prescriber needs to document your T2D diagnosis (ICD-10 E11.x), A1c of 6.5% or greater within ~90 days, and a prior trial of metformin plus one additional agent. These are the Express Scripts PA criteria for Mounjaro — without documented step therapy, the PA is likely to be denied. The prescriber submits through the Express Scripts portal; allow up to 72 hours.

If you want tirzepatide for weight loss, ask about Zepbound — not Mounjaro
If your goal is weight loss rather than diabetes management, Mounjaro is the wrong product — it is FDA-approved for type 2 diabetes only. The weight-loss tirzepatide is Zepbound, which has a separate FDA approval (chronic weight management and OSA) and a separate, more restrictive coverage pathway. Ask your prescriber and your Cigna plan specifically about Zepbound coverage — a different PA and tier than Mounjaro.
Options if Cigna 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. May be at a preferred tier ahead of Mounjaro as a required step-therapy agent on Express Scripts formularies.
Trulicity (dulaglutide)
FDA-approved for T2D. GLP-1 alternative that may be placed on a preferred tier ahead of Mounjaro; often used as the step-therapy agent prior to Mounjaro approval via Express Scripts.
Jardiance (empagliflozin)
SGLT2 inhibitor for T2D with cardiovascular benefits. May be required as step therapy before GLP-1 approval on Cigna/Express Scripts plans.
Zepbound (tirzepatide) — weight loss only
Same molecule as Mounjaro (tirzepatide) but FDA-approved for chronic weight management and OSA. Separate FDA approval, separate coverage track. For patients seeking tirzepatide for weight loss — not Mounjaro.
These options are listed for information only — your own clinician decides what is appropriate for you.
❓Frequently Asked Questions
No. Cigna does not cover Mounjaro for weight loss under any line of business. Mounjaro is FDA-approved for type 2 diabetes only; the Express Scripts PA is gated on a T2D diagnosis (ICD-10 E11.x) — off-label weight-loss requests (E66.x) are denied. For weight loss, the same active ingredient (tirzepatide) is sold as Zepbound, which has a separate FDA approval for chronic weight management and its own, more restricted, coverage pathway.
Cigna places Mounjaro as a non-preferred specialty drug at Tier 4/5 via Express Scripts, resulting in 25–33% coinsurance rather than a flat brand copay. By contrast, Aetna (CVS Caremark) lists Mounjaro as a preferred brand (Tier 2). The tier placement reflects each PBM's formulary negotiations. At 25–33% of the roughly $1,080–$1,560 monthly cost, Cigna's out-of-pocket exposure before hitting the plan OOP maximum is the highest among the major PBM-owned carriers — verify your exact coinsurance on myCigna.
Express Scripts requires a documented trial of metformin plus one additional agent before Mounjaro is approved. The second agent may be a sulfonylurea, SGLT2 inhibitor, or a preferred GLP-1 such as Ozempic or Trulicity. Without documented step therapy, the prior authorization is likely to be denied. Your prescriber submits this evidence through the Express Scripts PA portal; budget up to 72 hours for a decision. Criteria should be verified on the current Express Scripts formulary.
No. The 2026 Medicare GLP-1 Bridge ($50/month, July 1 – December 31, 2027) covers weight-loss-approved products only — Wegovy, Foundayo, and the Zepbound KwikPen. Mounjaro is excluded because it is FDA-approved for type 2 diabetes, not weight loss. Cigna Medicare Advantage and Part D plans cover Mounjaro for T2D under standard Part D rules with specialty-tier coinsurance and the $2,100 annual OOP cap in 2026.
Commercially insured Cigna members with Mounjaro coverage can use the Lilly savings card to pay as little as $25/month; those without coverage may pay $499/month (max $647/month, up to 13 fills, expires 12/31/2026). The card is not available to Medicare, Medicaid, Medicare Advantage, TRICARE, DoD, or VA beneficiaries. Verify current card terms at mounjaro.com/savings-card.
