Getting Mounjaro completely free is possible, but only if you meet specific income and insurance requirements. For most people, the realistic goal is reducing the cost dramatically rather than eliminating it entirely. Your best path depends on whether you have commercial insurance, qualify for government programs, or are uninsured.
The Manufacturer Savings Card
Eli Lilly offers a Mounjaro Savings Card that brings the cost down to as little as $25 for a one-month or three-month supply. To qualify, you need commercial (private) insurance. This includes employer-sponsored plans and marketplace plans, but not Medicare, Medicaid, or other government-funded coverage. The card expires on December 31, 2026, so this is a time-limited benefit worth activating now if you’re eligible.
You can get the card directly from Lilly’s Mounjaro website. It works like a coupon at the pharmacy, covering the gap between what your insurance pays and the retail price. If your insurance doesn’t cover Mounjaro at all, the savings card won’t help, since it’s designed to reduce your copay rather than replace insurance coverage entirely.
Lilly Cares: Free Mounjaro for Lower-Income Patients
The Lilly Cares Foundation is the most direct route to getting Mounjaro at zero cost. This patient assistance program provides Lilly medications for free to people who meet income and residency requirements. You must be a permanent U.S. resident, including Puerto Rico and the U.S. Virgin Islands.
Income limits are based on your household size and a percentage of the Federal Poverty Level. The thresholds vary by medication group, so the exact cutoff for Mounjaro depends on which group it falls into. As a reference, current annual income limits for a single person range from $47,880 (at 300% of the poverty level) up to $79,800 (at 500%), depending on the medication category. For a household of four, those numbers range from $99,000 to $165,000. If you live in Alaska or Hawaii, or have more than four people in your household, call 1-800-545-6962 for adjusted limits.
Applying requires a form that your doctor submits on your behalf. You’ll need to provide income documentation and confirm you don’t have coverage that already pays for the medication. Processing takes a few weeks, so plan ahead if you’re running low on refills.
Medicaid Coverage
Medicaid is required to cover Mounjaro for type 2 diabetes, since that’s an FDA-approved indication. If you have Medicaid and a diabetes diagnosis, you should be able to get Mounjaro at little or no cost, as Medicaid enrollees already pay minimal copays for prescription drugs. Expect your plan to require prior authorization, which means your doctor will need to submit paperwork justifying why Mounjaro is the right choice for you.
Coverage for weight loss is a different story. Only 13 state Medicaid programs covered GLP-1 medications for obesity treatment as of January 2026: Arizona, Colorado, Idaho, Kansas, Michigan, Minnesota, Mississippi, Nebraska, New York, Ohio, Oregon, Wisconsin, and Wyoming. A longstanding federal law allows states to exclude weight-loss drugs from Medicaid, so if you live outside those 13 states and don’t have a diabetes diagnosis, Medicaid likely won’t cover Mounjaro for you.
Medicare: Limited Options
Medicare Part D covers Mounjaro for type 2 diabetes, though your copay will depend on your specific plan. For weight loss, Medicare recently launched a GLP-1 Bridge program with a flat $50 copay for certain medications. However, Mounjaro is not currently included in that program. The eligible drugs are Zepbound (which contains the same active ingredient as Mounjaro but is approved for weight loss), Wegovy, and Foundayo.
If you’re on Medicare and want tirzepatide specifically for weight management, ask your doctor about Zepbound, which would qualify for the $50 bridge copay. For diabetes, standard Part D coverage applies to Mounjaro, and the Medicare Extra Help program can further reduce costs if your income is low enough to qualify.
Clinical Trials
Enrolling in a clinical trial is another way to receive tirzepatide (the active ingredient in Mounjaro) at no cost. Researchers studying the drug for various conditions sometimes provide it free to participants. Eligibility criteria are strict. A typical obesity trial might require a BMI over 30, an age between 35 and 60, and no history of cancer or use of certain other medications. Some trials also don’t provide the medication directly but instead study people who are already taking it through their own prescriptions.
You can search for active trials at ClinicalTrials.gov using “tirzepatide” as a keyword and filtering by your location. Trials are concentrated in major medical centers, so availability depends heavily on where you live. Be aware that you might be assigned to a placebo group rather than receiving the actual drug.
Pharmacy Discount Programs
If you don’t have insurance and don’t qualify for Lilly Cares, pharmacy discount tools like Optum Perks coupons can lower the price of Mounjaro. These won’t make it free, and the out-of-pocket cost will still be substantial compared to having insurance, but they can shave hundreds off the retail price. GoodRx and similar platforms work the same way, negotiating lower rates with pharmacies on your behalf.
For the best results, compare prices across multiple pharmacies using these tools. Costs can vary significantly between locations, even within the same city. Independent pharmacies and warehouse clubs like Costco sometimes offer lower prices than chain pharmacies for the same medication.
