Is Mounjaro Covered by Medicare for Diabetes?
Mounjaro, a medication with tirzepatide, helps manage type 2 diabetes effectively. Many Medicare beneficiaries wonder, is Mounjaro covered by Medicare for diabetes?
This article explains Medicare’s 2025 coverage for Mounjaro, costs, and ways to reduce expenses.
What Is Mounjaro?
Mounjaro is an injectable drug approved by the FDA in 2022 for type 2 diabetes. It lowers blood sugar by boosting insulin and slowing digestion. Tirzepatide, its active ingredient, also promotes weight loss.
Administered weekly via pre-filled pens, it’s used with diet and exercise. It’s not approved for weight loss, but doctors may prescribe it off-label. Coverage depends on your Medicare plan.
How Medicare Covers Prescription Drugs
Medicare covers drugs through Part D (prescription drug plans) or Medicare Advantage (Part C) plans with drug coverage. Each plan has a formulary, a list of covered medications. Formularies vary by plan and state.
Part D plans often cover diabetes drugs like Mounjaro. Medicare Advantage plans may also include Mounjaro if it’s on their formulary. Checking your plan’s details is essential.
Is Mounjaro Covered by Medicare for Diabetes?
Is Mounjaro covered by Medicare for diabetes? Yes, most Medicare Part D and Medicare Advantage plans cover Mounjaro for type 2 diabetes, its FDA-approved use. Coverage typically requires prior authorization to confirm medical necessity.
About 76% of Medicare drug plans include Mounjaro, but specifics vary. It’s often listed as a Tier 3 drug, meaning higher copays. Contact your plan to confirm coverage.
Why Mounjaro Isn’t Covered for Weight Loss
Medicare does not cover Mounjaro for weight loss, as it’s an off-label use. A 2003 law prohibits Medicare from covering weight-loss drugs. This applies even if Mounjaro causes weight loss in diabetic patients.
Zepbound, another tirzepatide drug, is approved for weight loss but covered only for conditions like obstructive sleep apnea (OSA). Coverage for diabetes remains Mounjaro’s primary use.
Prior Authorization Requirements
Medicare plans often require prior authorization for Mounjaro. Your doctor must submit evidence, like high A1C levels or failed trials of other drugs. This proves Mounjaro is necessary for your diabetes.
The process may take days or weeks. Denials can occur if criteria aren’t met. Your doctor’s thorough documentation improves approval chances.
Costs of Mounjaro with Medicare
Mounjaro’s cost with Medicare depends on your plan’s formulary and coverage stage. In the deductible stage, you pay the full price, around $1,000–$1,200 monthly. After meeting the deductible, copays or coinsurance apply.
In 2025, Part D plans cap out-of-pocket costs at $2,000 annually. Copays for Tier 3 drugs like Mounjaro can range from $35–$100 monthly. Check your plan for exact costs.
Table: Mounjaro Costs with Medicare Part D (2025)
| Coverage Stage | Your Cost | Notes |
|---|---|---|
| Deductible | $1,000–$1,200/month (full price) | Until deductible is met |
| Initial Coverage | $35–$100/month (copay/coinsurance) | After deductible, varies by plan |
| Coverage Gap (Donut Hole) | Higher copays until $2,000 cap | Temporary cost increase |
| Catastrophic Coverage | $0–$5/month | After reaching $2,000 out-of-pocket |
Note: Costs are approximate and vary by plan.
Medicare Extra Help Program
The Medicare Extra Help program assists low-income beneficiaries with drug costs. It covers premiums, deductibles, and copays for drugs like Mounjaro. Eligibility requires income below $22,590 for individuals in 2025.
Apply through the Social Security Administration online or by calling 1-800-772-1213. Extra Help can reduce Mounjaro copays to $4–$10 monthly. This program is a lifeline for many.
Using Preferred Pharmacies
Medicare Part D plans often have preferred pharmacies offering lower prices. Using these can reduce Mounjaro’s cost significantly. Non-preferred pharmacies may charge more, increasing your out-of-pocket expenses.
Check your plan’s pharmacy network online or call customer service. Filling prescriptions at preferred pharmacies saves money. This is especially important for expensive drugs like Mounjaro.
Mail-Order Pharmacy Benefits
Some Medicare plans cover mail-order pharmacies for Mounjaro. These services deliver a 90-day supply, often at a lower cost. Mail-order is convenient and may reduce copays compared to retail pharmacies.
Ask your plan if mail-order is available. Ensure the pharmacy is in-network to maximize savings. This option suits patients with stable prescriptions.
Lilly’s Savings Card Limitations
Eli Lilly offers a Mounjaro Savings Card, reducing costs to $25 for a 1–3-month supply. However, it’s only for commercial insurance holders with a diabetes diagnosis. Medicare beneficiaries, including Part D or Advantage plan users, are ineligible.
Without the card, Medicare patients rely on plan coverage or discounts. Contact Lilly at 1-844-805-5807 for other assistance options. Alternative programs may be available.
Out-of-Pocket Cost Caps in 2025
In 2025, Medicare Part D introduces a $2,000 annual out-of-pocket cap. Once reached, you pay $0–$5 monthly for covered drugs like Mounjaro. This cap includes deductibles, copays, and coinsurance.
You can also opt for a payment plan to spread costs monthly. Track your spending to budget effectively. This change makes Mounjaro more affordable for many.
Appealing a Coverage Denial
If your plan denies Mounjaro, you can appeal. Request the denial letter to understand the reason, like insufficient documentation. Your doctor can submit an appeal with updated records, such as A1C results.
Appeals may take weeks, and success isn’t guaranteed. Persistence and strong medical evidence are key. Contact your plan for appeal instructions.
Alternatives to Mounjaro
If Mounjaro isn’t covered or is too costly, other diabetes drugs are available. Options like Ozempic or Trulicity, also GLP-1 agonists, may be on your plan’s formulary. These work similarly but differ in cost and coverage.
Your doctor can suggest alternatives based on your needs. Some plans favor cheaper drugs, requiring step therapy. Discuss options to find a covered medication.
Compounded Tirzepatide Risks
Compounded tirzepatide, a cheaper alternative to Mounjaro, costs $250–$400 monthly. Available through telehealth, it’s not FDA-approved and carries risks. Quality and potency may vary, potentially affecting safety.
Medicare doesn’t cover compounded drugs. The FDA warns against their use due to lack of oversight. Consult your doctor before considering this option.
Lilly Cares Assistance Program
Lilly Cares provides free Mounjaro to low-income, uninsured patients with diabetes. Eligibility requires U.S. residency and income below 400% of the federal poverty level. Medicare patients don’t qualify, as they’re insured.
Apply online at LillyCares.com or call 1-800-545-5979. This program suits uninsured patients but not Medicare beneficiaries. Other discounts may apply for Medicare users.
Working with Your Doctor
Your doctor is crucial for securing Mounjaro coverage. They can submit prior authorization requests with detailed medical records. For denials, they can recommend alternatives or assist with appeals.
Share your Medicare plan details with your doctor. Regular check-ins ensure your treatment aligns with coverage rules. Collaboration maximizes your chances of approval.
Future Medicare Changes
A 2026 CMS proposal could expand Medicare coverage for weight-loss drugs, potentially affecting Mounjaro. The Treat and Reduce Obesity Act may lift the 2003 ban, allowing coverage for obesity-related uses. These changes are uncertain but promising.
Stay updated via Medicare.gov or news outlets. Policy shifts could lower costs for Mounjaro users. For now, coverage remains limited to diabetes.
Tips for Managing Costs
To reduce Mounjaro costs with Medicare, plan carefully. Use preferred pharmacies and explore mail-order options. Apply for Extra Help if eligible.
Here are some strategies:
- Check your plan’s formulary for Mounjaro’s tier.
- Use GoodRx or SingleCare for discounts if paying out of pocket.
- Track spending to reach the $2,000 cap faster.
