Mounjaro Savings Card: How to Get $25/Month (2026 Guide)

What is the Mounjaro savings card?

Mounjaro is tirzepatide, a dual GIP and GLP-1 receptor agonist that Eli Lilly markets specifically for type 2 diabetes. The FDA approved it for T2D in 2022. The Mounjaro savings card is Lilly's copay reduction program for patients who have commercial insurance and a valid Mounjaro prescription for diabetes. It does not replace insurance and it is not a coupon you clip and hand over. It is applied at the pharmacy counter at the moment your prescription is dispensed, after your insurance has processed the claim.

The list price for Mounjaro is $1,112.16 per month, per Lilly's official pricing page. Almost no insured T2D patient pays that. The savings card exists to bridge the gap between your plan's copay and a much lower out-of-pocket figure, which for most eligible patients lands at the $25 minimum. For the full picture across every pricing tier, including Medicare and cash-pay routes, see the Mounjaro Cost Guide. This article focuses specifically on the savings card access flow.

Mounjaro vs Zepbound savings programs: what is the difference?

Mounjaro and Zepbound both contain tirzepatide, but they are separate brands with separate savings programs. The Mounjaro savings card is tied to the type 2 diabetes indication and the KwikPen format. Zepbound carries the obesity and chronic weight management indication and runs its own distinct card with different terms. Using the wrong card for the wrong indication results in a pharmacy rejection. This guide covers the Mounjaro card only. If you were prescribed tirzepatide for weight management, the Zepbound program is the relevant one, and the Mounjaro vs Zepbound comparison explains which brand fits which situation.

Eligibility: who qualifies for the Mounjaro savings card?

Eligibility is where most people trip up, so here are the exact rules. There are two savings tiers. Which one applies to you depends on whether your commercial plan covers Mounjaro. Government insurance disqualifies you from both.

Who qualifies for the Mounjaro savings card at the $25 tier versus who is excluded.

Tier 1: commercially insured patients (the $25 tier)

This is the tier most people mean when they look up the Mounjaro savings card. To qualify:

• You have commercial insurance (employer plan, ACA marketplace plan, or similar private coverage) that covers Mounjaro.
• You have a valid Mounjaro prescription for type 2 diabetes.
• You are not enrolled in Medicare, Medicaid, Medicare Advantage, TRICARE, the VA, the DoD, or any state prescription drug assistance program.
• Monthly copay: as little as $25 per fill.
• Savings cap: up to $150 per 1-month fill, $300 per 2-month fill, $450 per 3-month fill.
• Annual savings cap: up to $1,950 per calendar year.
• The program runs through December 31, 2026.

Tier 2: commercially insured but your plan does not cover Mounjaro

If you have commercial insurance but your specific plan excludes Mounjaro from its formulary, you are still eligible for savings, just at a higher floor. The terms for this tier:

• Minimum cost: as low as $499 per 1-month fill.
• Monthly savings maximum: up to $647.
• Annual savings maximum: up to $8,411.

Who cannot use the savings card?

Federal law sets these exclusions, not Lilly. They do not bend:

• Medicare Part D patients. Federal anti-kickback rules prohibit manufacturer copay assistance on government-funded prescriptions.
• Medicaid patients. Same statutory restriction applies.
• TRICARE, VA, DoD, and state assistance program patients. All government-funded coverage is excluded.
• Patients without a valid Mounjaro prescription for type 2 diabetes. The card is indication-specific.

If you are on Medicare Part D, the savings card is off the table, but you are not without cost protection. Since January 1, 2025, Medicare Part D has carried an annual out-of-pocket cap under the Inflation Reduction Act redesign. It is indexed and rises each year: $2,000 in 2025, $2,100 in 2026 and $2,400 in 2027 (CMS and Medicare.gov, checked October 2, 2026). Because Mounjaro holds an FDA-approved T2D indication, Part D plans cover it for diabetes, and that cap is the main mechanism that limits your total yearly spend.

How to get the Mounjaro savings card step by step

Enrollment is simple once you do the steps in the right order. There are five:

1. Get a Mounjaro prescription from your prescriber for type 2 diabetes.
2. Confirm your commercial insurance covers Mounjaro by calling the pharmacy benefits number on the back of your insurance card.
3. Enroll in the savings program at mounjaro.lilly.com or through Lilly's patient portal at startlilly.com.
4. Bring the card to the pharmacy counter, either printed or on your phone, so it can be applied at dispensing.
5. Refill within the dispensing window each cycle to keep your eligibility and pricing active.

Does the savings card require a separate application?

Enrollment happens once, online, through Lilly's portal. After that, the card is applied automatically at dispensing at participating pharmacies, with no separate claims submission on your end. The step that trips people up is not the card itself: it is the prior authorization. Most commercial plans require your prescriber to submit a prior authorization documenting your type 2 diabetes diagnosis before the plan will cover Mounjaro. The savings card cannot reduce your copay until the underlying claim is approved, so the prior authorization usually needs to clear first.

Common reasons the Mounjaro savings card does not work

The pharmacy counter rarely explains why this happens. When the card does not bring your cost down to $25, it is almost always one of these:

• Your plan does not cover Mounjaro at any formulary tier. The card reduces copay on covered claims. It cannot substitute for missing coverage, and this drops you into Tier 2.
• Prior authorization has not been approved yet. Until the PA clears, the claim is not payable and the card has nothing to reduce.
• You are a Medicare or Medicaid patient. The card is blocked at the system level for government-funded coverage.
• The annual savings cap is exhausted. Once you hit the $1,950 Tier 1 ceiling for the calendar year, the card stops reducing cost until the next year.
• The card was not transmitted to the pharmacy's PBM system. Sometimes the BIN, PCN, or Group number was entered incorrectly or not at all.
• The prescription was written for weight loss rather than T2D. Mounjaro is a diabetes brand. A weight-loss-coded script may not be covered the same way, and the Mounjaro card will not apply.

What to do if the savings card is rejected

Work this checklist in order before assuming the card itself is broken:

• Call Lilly patient services using the support number printed on your savings card.
• Ask your prescriber's office to confirm or resubmit the prior authorization for the T2D diagnosis.
• Ask your insurer which formulary tier Mounjaro sits on, or whether it is covered at all.
• Ask the pharmacist to re-run the claim using the exact BIN, PCN, and Group numbers from the card.

Alternatives if you cannot use the savings card

If you are a Medicare patient, your commercial plan does not cover Mounjaro, or you simply cannot get the card to work, there are still regulated routes to lower cost.

LillyDirect self-pay: the $499 Mounjaro pen, and why Zepbound is cheaper

For Mounjaro itself, LillyDirect lists the single-dose prefilled pen at a self-pay price starting at $499/month at every strength from 2.5mg to 15mg (checked October 2, 2026). A valid prescription is required and terms apply. There is no lower dose tier for Mounjaro.

The cheaper prices you may have seen belong to Zepbound, Lilly's other tirzepatide brand. Zepbound contains the same molecule, but it is a separate product approved for weight management and obstructive sleep apnoea rather than for blood-sugar control, so it needs its own prescription for those uses. Its LillyDirect self-pay prices, checked October 2, 2026, apply to both its vials and its KwikPen:

• $299/month for the 2.5mg dose.
• $399/month for the 5mg dose.
• $449/month for 7.5mg through 15mg doses when you refill within 45 days ($499 for 7.5mg and $699 for 10mg to 15mg otherwise).

Zepbound Self Pay Journey Program pricing on LillyDirect (unchanged when checked October 2, 2026). Mounjaro self-pay starts at $499/month at every strength.

Both routes are genuine Lilly-manufactured product, not compounded copies. Bulk-compounded copies of tirzepatide are no longer legally permissible following the FDA shortage resolution in early 2025. Zepbound vials hold a ready-to-inject solution, so there is nothing to reconstitute; you draw the dose with a needle and syringe. For Zepbound's full enrollment walkthrough, see the LillyDirect Zepbound self-pay vials guide.

Medicare Part D and the annual out-of-pocket cap

Medicare Part D covers Mounjaro specifically for type 2 diabetes, because Mounjaro holds the FDA-approved T2D indication. Since January 1, 2025, Part D has had an annual out-of-pocket cap under the Inflation Reduction Act redesign, indexed each year: $2,000 in 2025, $2,100 in 2026 and $2,400 in 2027. For Medicare beneficiaries with T2D, that cap, not the savings card, is the primary cost-protection mechanism. The card is excluded for Medicare patients by law, but the cap makes annual spend predictable in a way it was not before 2025.

GoodRx and third-party coupons

GoodRx and similar coupon services typically bring branded Mounjaro pens to roughly $900 to $1,100 at major pharmacy chains like Walmart, Walgreens, and Kroger. That is still higher than LillyDirect's $499/month self-pay price for the Mounjaro pen, so third-party coupons are useful mainly when LillyDirect is not an option for you. They are not a replacement for the savings card and do not stack with it.

Mounjaro savings card vs Zepbound savings card side by side

Both cards cover the same molecule, tirzepatide, but they are indication-specific. Presenting the wrong card for the wrong prescription will get rejected at the counter.

Confirm which brand your prescription is for before you enroll. Same drug, two programs, and the indication on the script decides which card the pharmacy system will accept.
