Mounjaro cost with insurance
Mounjaro is the one card here that still pays when your plan says no. With coverage, Lilly's card brings a fill toward $25; without it, the same card sets a fixed price instead — and both carry ceilings that the headline does not print.
How much is Mounjaro with insurance?
With a plan that covers Mounjaro, the Mounjaro Savings Card brings a fill to as little as $25. It takes off at most $150 a month and $1,950 a year, so $25 is what you pay only when your plan's own copay is $175 or less; above that, you pay the difference. Without coverage the same card switches to a fixed price with its own monthly and yearly ceilings, set out in the card's terms on this page. Paying cash, Mounjaro is $499 a month once titrated, read from its own published page on 2026-09-11.
What the card leaves you paying
“As little as $25 for a 1-, 2- or 3-month fill” is the headline. The cap behind it decides whether that is your price: the card pays the part of your copay above $25, up to $150 a month, so the higher your plan places Mounjaro on its formulary, the less of the headline you see.
| Your plan's copay for a month | The card pays | You pay |
|---|---|---|
| $50 | $25 | $25 |
| $175 | $150 | $25 |
| $250 | $150 | $100 |
| $500 | $150 | $350 |
Arithmetic on the card's published cap, not a quote: your plan's copay for Mounjaro is on its formulary. The yearly ceiling of $1,950 is $150 across 13 fills, because the maker counts a month as 28 days.
The terms: Capped at $150 of savings a month and $1,950 a year. Without coverage the same card lets you pay as little as $499 for a 28-day fill, with Lilly's savings in that case capped at $647 a month and $8,411 a year.

A diabetes drug, including for children from 10
Mounjaro's label carries two indications, both in type 2 diabetes: glycemic control in adults and in children 10 and older, and reducing the risk of heart attack, stroke and cardiovascular death in adults with type 2 diabetes at high risk of those events. Tirzepatide for weight or for sleep apnea is sold as Zepbound.
A plan covers it on its diabetes criteria, which turn on the diagnosis rather than on weight. Prescribed without diabetes it is off-label, and the tirzepatide prescription a plan will consider for weight is Zepbound's.
The pediatric indication matters to families on a commercial plan: Zepbound is approved for adults only, so for a child with type 2 diabetes, tirzepatide means Mounjaro.
Indications read from FDA prescribing information for MOUNJARO, via DailyMed.
If your plan says no
Find out which refusal it is first. A prior-authorization denial means the plan covers Mounjaro and says this request did not meet its criteria; that has a deadline and an appeal. An exclusion means the benefit was never bought, so no appeal reaches it, and the question is for whoever chose the plan.
A standard prior authorization has to be decided within 15 days of the request, extendable once by 15; an urgent one within 72 hours. You have at least 180 days from a denial to appeal inside the plan, then four months from the final denial to ask for independent external review, unless the plan is grandfathered. 29 CFR 2560.503-1; 45 CFR 147.136

Every route, and what it costs
| Your situation | What you pay |
|---|---|
| A plan that covers it, with the card | As little as $25 for a 1-, 2- or 3-month fill, within the caps above |
| The card's yearly ceiling reached | Your plan's copay in full, until the card resets |
| A plan that excludes it | Without coverage the same card switches to a fixed price with its own monthly and yearly ceilings, set out in the card's terms on this page. Self-pay: $499 a month once titrated |
| Medicare, Medicaid or TRICARE | The card is barred — federal anti-kickback rules. Your plan's own rules decide instead. |

Your insurer, and the other routes
Mounjaro with insurance, answered
- How much is Mounjaro with insurance?
- With a plan that covers it, as little as $25 on the maker's card, which takes off at most $150 a month and $1,950 a year. A copay above $175 leaves you paying the difference — $400 becomes $250. If your plan does not cover Mounjaro, the self-pay price is $499 a month once titrated.
- Does insurance cover Mounjaro for weight loss?
- Not on its label: both of Mounjaro's indications are in type 2 diabetes, and a plan asked to cover it for weight alone treats that as off-label. The tirzepatide approved for weight is Zepbound.
- Can a child use Mounjaro with commercial insurance?
- The label covers children 10 and older with type 2 diabetes, so a plan judges a child's request on its diabetes criteria like an adult's. Zepbound has no pediatric indication.
