Mounjaro's savings card has the most generous cap of any of them. $150 a month, against $100 for Zepbound and $100 for Novo's Ozempic and Wegovy cards. Same manufacturer as Zepbound, same molecule, better terms.
People search for this as the Mounjaro coupon; Lilly calls it a savings card. It is worth knowing because “the Lilly savings card” gets talked about as one thing and it is four things. The Zepbound half works differently.
If your plan covers Mounjaro
Lilly's terms:1
...insurance that covers Mounjaro (tirzepatide) ... to pay as little as $25 for a 1-month, 2-month, or 3-month prescription fill. ... Card savings are subject to a maximum monthly savings of up to $150 per 1-month prescription.
Lilly, Mounjaro savings
The structure is the same as every card in this category: a $25 headline, and a cap that decides whether you get near it.
| Your copay | Card takes off | You pay |
|---|---|---|
| $100 | $75 | $25 |
| $175 | $150 | $25 |
| $300 | $150 | $150 |
| $500 | $150 | $350 |
Why the cap is worth comparing
The four major cards in this market, side by side, all quoted from the manufacturers:
| Card | Headline | Cap, 1-month fill |
|---|---|---|
| Mounjaro | as little as $25 | $150 |
| Zepbound | as little as $25 | $100 |
| Ozempic | as little as $25 | $100 |
| Wegovy | as little as $25 | $100 |
On a $250 copay, the Mounjaro card leaves you paying $100 and the Zepbound card leaves you paying $150, for the same molecule from the same company. The difference is which indication the box is labelled for.
Zepbound's cap, for the comparison, in Lilly's own words:3
Card savings are subject to a maximum monthly savings of up to $100 per 1-month prescription.
Lilly, Zepbound
If your plan does not cover Mounjaro
A different program applies, and its numbers are unusually specific:2
...drug insurance that does not cover Mounjaro ... to pay as low as $499 for a 1-month prescription fill ... maximum monthly savings of up to $647 and a separate maximum annual savings of up to $8,411 per calendar year. Card may be used for a maximum of up to 13 prescription fills per calendar year.
Lilly
Two things people miss in that paragraph. There is an annual ceiling of $8,411 as well as a monthly one, so heavy use can exhaust the program before the year does. And the fill limit is 13, which is one more than a monthly prescription needs, not a generous allowance.
Who is excluded
Government beneficiaries, which means Medicare and Medicaid. That is standard across manufacturer copay cards and it is not specific to Lilly. If that is you, the card is not your route and the coverage question is a different one.
What it is competing against
We rank cash-pay programs and earn commission on some of them. We earn nothing from Lilly's card, so plainly: if it gets you to $25, take it. Nothing on our board beats that.
It stops being the cheapest route if you are excluded, if your plan does not cover Mounjaro so you are on the $499 program, or if your copay minus $150 is still above the cash market:
One thing to check first
Whether your plan covers Mounjaro specifically. Formularies routinely treat the diabetes brand and the weight brand differently even though both are tirzepatide from Lilly, so the answer for one tells you nothing about the other. What the major insurers publish is the place to start.
