Will Medicare Pay for Mounjaro? A Clear Guide
Mounjaro is a popular medication for type 2 diabetes, but many wonder, “Will Medicare pay for Mounjaro?” Coverage depends on your Medicare plan and the drug’s prescribed use.
This guide explains Medicare’s coverage for Mounjaro, how to check it, and options if it’s not covered. With simple steps, you’ll understand your benefits and costs.
What Is Mounjaro?
Mounjaro, or tirzepatide, is a weekly injectable drug. It’s FDA-approved for adults with type 2 diabetes to manage blood sugar. Some use it off-label for weight loss, though it’s not approved for this. It mimics GLP-1 and GIP hormones, regulating insulin and appetite.
The drug comes in a pre-filled KwikPen, delivering four doses monthly. Its effectiveness makes it a top choice, but coverage varies. Knowing its purpose helps clarify if Medicare will pay for Mounjaro.
Medicare and Prescription Drug Coverage
Medicare covers prescription drugs through Part D or Medicare Advantage (Part C) plans with drug coverage. Each plan has a formulary, a list of covered drugs. Mounjaro’s coverage depends on whether it’s included and for what purpose.
Part A and Part B don’t cover self-administered drugs like Mounjaro. Part D plans, managed by private insurers, often cover it for type 2 diabetes. Checking your plan’s formulary is key to answering, “Will Medicare pay for Mounjaro?”
Does Medicare Cover Mounjaro?
Medicare Part D and some Medicare Advantage plans often cover Mounjaro for type 2 diabetes, its FDA-approved use. Coverage usually requires prior authorization to confirm medical necessity. Off-label use for weight loss is typically not covered. About 76% of Medicare drug plans include Mounjaro, but not all.
Mounjaro is usually a Tier 3 or higher drug, meaning higher copays. Without coverage, it costs $1,000–$1,200 monthly. Log into your Medicare plan’s website to check your formulary.
Prior authorization involves your doctor submitting medical records. They must show Mounjaro is needed for type 2 diabetes, often after trying other drugs. This step ensures Medicare approves coverage.
In 2025, Medicare Part D caps out-of-pocket drug costs at $2,000 annually. This helps if Mounjaro is covered, reducing your expenses after reaching the cap.
Factors Affecting Mounjaro Coverage
Several factors determine if Medicare will pay for Mounjaro. These include:
- Plan Type: Part D or Medicare Advantage plans have different formularies.
- Diagnosis: Coverage is likely for type 2 diabetes, not weight loss.
- Prior Authorization: Most plans require this to verify medical need.
- Formulary Tier: Higher tiers mean higher copays for Mounjaro.
- Pharmacy Choice: Preferred pharmacies may offer lower costs.

How to Check Mounjaro Coverage
To confirm if Medicare will pay for Mounjaro, follow these steps:
Step 1: Access Your Plan’s Website
Log into your Part D or Medicare Advantage plan’s portal. Navigate to the formulary section. Search for Mounjaro (tirzepatide) to see its status.
Step 2: Review the Formulary
Check if Mounjaro is listed and note its tier. Look for notes on prior authorization or step therapy. If it’s not included, coverage is unlikely.
Step 3: Call Your Plan
Use the customer service number on your Medicare card. Ask if Mounjaro is covered for type 2 diabetes. Confirm copays, deductibles, and authorization needs.
Step 4: Talk to Your Doctor
Discuss Mounjaro with your healthcare provider. They can submit prior authorization forms, documenting your diabetes and prior treatments. This step is critical for approval.
Step 5: Use Medicare Plan Finder
Visit Medicare.gov’s Plan Finder tool. Enter your zip code and medications to compare plans. This helps find plans covering Mounjaro during open enrollment.
What If Medicare Doesn’t Cover Mounjaro?
If Medicare denies Mounjaro coverage, you have options. Review the denial notice to understand the reason. Common issues include off-label use or missing prior authorization.
Your doctor can appeal the denial, providing more medical evidence. Appeals may take weeks, so stay in touch with your plan. Ensure your doctor includes detailed records.
Eli Lilly’s Mounjaro Savings Card isn’t available for Medicare patients. However, discount programs like GoodRx can lower costs to $998–$1,000 monthly. Compare prices at local pharmacies.
The Medicare Extra Help program can reduce Part D costs for low-income beneficiaries. It covers premiums, deductibles, and copays if you qualify. Apply through the Social Security Administration.
Ask your doctor about alternatives like Ozempic or Trulicity. These GLP-1 drugs may be covered by your plan. Zepbound, approved for weight loss, is another option but rarely covered.
Costs of Mounjaro With and Without Medicare
Mounjaro’s cost varies based on coverage. With Medicare, copays depend on the drug’s tier. Without coverage, expenses are high.
| Scenario | Estimated Cost | Details |
|---|---|---|
| With Medicare Part D | $50–$200/month | Tier 3 copay, after deductible |
| Without Coverage | $1,000–$1,200/month | Full retail price |
| With GoodRx Discount | $998–$1,000/month | Varies by pharmacy |
In 2025, Medicare’s $2,000 out-of-pocket cap reduces costs after you meet it. Use preferred pharmacies to lower copays.
Tips to Improve Coverage Chances
Increase the likelihood that Medicare will pay for Mounjaro with these tips:
- Work with Your Doctor: Ensure they document type 2 diabetes and failed treatments.

Other Considerations for Mounjaro Use
Mounjaro is injected weekly into the thigh, abdomen, or upper arm. Side effects include nausea, diarrhea, or injection site bruising. These often decrease over time. Report persistent issues to your doctor.
Store pens in the refrigerator before use. After the first dose, keep them at room temperature for up to 30 days. Check for cloudiness or particles before injecting.
Dosing starts at 2.5 mg weekly, increasing to 15 mg as needed. Follow your doctor’s instructions carefully. Never take two doses within four days.
For weight loss, Medicare doesn’t cover Mounjaro, but future policy changes may allow it. Zepbound, with the same ingredient, is approved for weight loss but rarely covered.
When to Contact Medicare or Your Doctor
If you’re unsure about coverage, call your Part D or Medicare Advantage plan. They can explain formulary details and authorization steps. Have your plan ID ready for quick assistance.
Contact your doctor if prior authorization is denied. They can revise the request or suggest alternatives like Ozempic. Report severe side effects, like intense stomach pain, immediately.
Seek urgent care for serious reactions, such as allergic symptoms. Keep your plan’s contact number and doctor’s office accessible for emergencies.
