Mounjaro prices (checked on October 6, 2026)
| How you pay | What you pay | Main conditions |
|---|---|---|
| Original (list) price | $1,112.16 per month (single-dose pen) | Price before discounts, as shown on TrumpRx |
| Self-pay through LillyDirect or TrumpRx | $499 per month, 2.5 mg to 15 mg single-dose pens | Valid prescription; processed outside insurance; terms apply |
| Commercial insurance that covers Mounjaro + savings card | As little as $25 for up to a 3-month prescription | Maximum savings $150 (1 month), $300 (2 months) or $450 (3 months) per fill; up to $1,950 a year; 13 fills a year; expires December 31, 2026 |
| Commercial insurance that does not cover Mounjaro + savings card | As low as $499 for a 1-month fill | Maximum savings $647 a month, $8,411 a year; 13 fills a year; expires December 31, 2026 |
| Medicare Part D (type 2 diabetes) | Your plan’s cost sharing | Deductible no more than $615 and out-of-pocket drug costs capped at $2,100 in 2026 |
| Medicaid (type 2 diabetes) | State copay rules | Medicaid must cover drugs approved for diabetes; prior authorization is common |
Why the list price still matters. Few people pay the original price, but it can drive what you owe if you have a high-deductible plan or pay coinsurance (a percentage of the drug’s price) rather than a flat copay, because those amounts are often calculated from the list price. If that applies to you, compare your plan’s charge with the $499 self-pay price before each fill, and ask whether the savings card applies.
Children and teens. Mounjaro’s label includes children 10 and older with type 2 diabetes, with a lower maximum dose than for adults. Doses for young people are set by their prescriber, and coverage rules can differ for children’s plans and Medicaid, so ask the plan directly.
The Mounjaro savings card, in detail
Lilly’s Mounjaro savings card has two versions. With commercial insurance that covers Mounjaro, eligible people pay as little as $25 for a prescription of up to three months; Lilly defines one month as 28 days and up to 4 pens, and three months as 84 days and up to 12 pens. Savings are capped at $150 for a one-month fill, $300 for two months and $450 for three months, up to $1,950 per calendar year and 13 fills. With commercial insurance that does not cover Mounjaro, the card brings a one-month fill to as low as $499, with savings capped at $647 a month and $8,411 a year. Both versions expire on December 31, 2026, and neither can be used by anyone enrolled in a state, federal or government-funded program, including Medicaid, Medicare, Part D and Medicare Advantage.
| Item | Value |
|---|---|
| 1-month fill, maximum savings | $150 |
| 2-month fill, maximum savings | $300 |
| 3-month fill, maximum savings | $450 |
| Per calendar year, maximum | $1,950 |
You pay as little as $25 per fill until these limits are reached; above them you pay the rest of your plan's charge.

What affects what you pay
- Dose does not change the self-pay price. Unlike Zepbound’s self-pay program, LillyDirect lists the same $499 for every Mounjaro pen strength from 2.5 mg to 15 mg. The label describes starting at 2.5 mg and increasing by 2.5 mg after at least four weeks; your prescriber sets the schedule.
- Insurance or self-pay. Self-pay fills are processed outside insurance, so ask your plan whether that spending counts toward your deductible or out-of-pocket maximum.
- Why it is prescribed. Plans generally cover Mounjaro for type 2 diabetes, often with prior authorization; prescriptions for weight loss alone are off label and often not covered.
- Forms. The label lists single-dose pens, vials and a KwikPen; the self-pay prices checked today were for single-dose pens.
Medicare and Medicaid
Part D plans cover GLP-1 medicines prescribed for type 2 diabetes under their normal cost sharing, according to KFF. In 2026 the Part D deductible is at most $615, and once your out-of-pocket spending on covered drugs reaches $2,100 you pay nothing more for covered drugs for the rest of the year. Extra Help lowers costs for people with limited income, and the Medicare Prescription Payment Plan can spread out-of-pocket costs into monthly bills (it does not lower the total). Mounjaro is not part of the temporary Medicare GLP-1 Bridge, which is for weight management and includes Zepbound KwikPen instead. Medicaid programs must cover drugs approved for diabetes, typically with prior authorization.
If your plan says no: prior authorization and appeals
Plans often require prior authorization for GLP-1 medicines; KFF notes that even where Medicaid covers them, utilization controls such as prior authorization are typical. If a claim or authorization is denied, federal rules for most plans give you the right to appeal. According to HealthCare.gov, you must file an internal appeal within 180 days of the denial notice; the plan must decide within 30 days for a medicine you have not yet received (60 days for care already received), and urgent cases must be decided as quickly as your condition requires, no later than 4 business days. If the plan still says no, you can ask for an independent external review within 4 months; standard reviews are decided within 45 days, expedited ones within 72 hours, the fee (if any) cannot exceed $25, and the insurer must accept the reviewer’s decision.
Appeal timeline for most health plans (HealthCare.gov)
- Denial noticeRead the reason and ask your prescriber for a letter of medical necessity.
- Internal appealFile within 180 days of the denial.
- Plan decisionWithin 30 days for a medicine not yet received; urgent cases faster.
- External reviewRequest within 4 months of the final denial.
- Final decisionWithin 45 days (72 hours if expedited); binding on the insurer.
Medicare Part D has its own coverage-determination and appeal process; your plan’s denial letter explains the steps. Our GLP-1 coverage guide has more detail and a checklist for your prescriber.
Mounjaro vs Zepbound cost
Mounjaro and Zepbound contain the same active ingredient, tirzepatide, but are approved for different uses: Mounjaro for type 2 diabetes in adults and children 10 and older (and for reducing major cardiovascular events in adults with type 2 diabetes at high cardiovascular risk), Zepbound for chronic weight management and obstructive sleep apnea in adults with obesity. Their self-pay prices differ:
| Item | Mounjaro (single-dose pen) | Zepbound (KwikPen or vial, on-time refills) |
|---|---|---|
| 2.5 mg | $499 | $299 |
| 5 mg | $499 | $399 |
| 7.5 mg | $499 | $449 |
| 10 mg | $499 | $449 |
| 12.5 mg | $499 | $449 |
| 15 mg | $499 | $449 |
Different approved uses and forms; a prescription for one is not interchangeable with the other. Zepbound higher doses are $499-$699 without on-time refills.

Choosing a brand because of price is a prescriber decision, because the approved use, the form and your coverage all matter. Details: Zepbound cost and semaglutide vs tirzepatide.
What a year of self-pay Mounjaro costs
Because LillyDirect’s self-pay price is the same at every strength, twelve monthly fills at $499 come to $5,988 a year (checked on October 6, 2026), compared with $13,345.92 at the $1,112.16 original price. With covering commercial insurance and the savings card, the out-of-pocket cost can be much lower until the card’s $1,950 yearly limit is reached. LillyDirect lists Mounjaro as FSA/HSA eligible, with eligibility varying by plan, and the IRS counts prescribed medicines as medical expenses.
| Item | Value |
|---|---|
| At the original (list) price | $13,345.92 |
| At LillyDirect self-pay | $5,988 |

Ways to lower the cost, and what to avoid
- Ask your plan about formulary status, tier and prior authorization for type 2 diabetes.
- Use the savings card if you have commercial coverage; compare it with self-pay if your plan does not cover Mounjaro.
- On Medicare, check Extra Help and the Medicare Prescription Payment Plan.
- Ask about alternatives if cost is a barrier; never stop a diabetes medicine without your prescriber, because blood sugar can rise.
- Avoid unapproved tirzepatide. Compounded or “research” tirzepatide is not Mounjaro and is not FDA approved, and the FDA determined in December 2024 that the tirzepatide injection shortage was resolved. See compounded GLP-1s.
