Does Molina Medicare Cover Mounjaro? Medicare Advantage Coverage Guide 2026
If you’re enrolled in with Molina Medicare Advantage (administered by Molina Healthcare) frequently want to know whether Molina Medicare covers Mounjaro (tirzepatide). The short answer is: coverage is determined by specific formulary placement and clinical criteria.
Molina Medicare’s Formulary Position on Mounjaro
Molina Medicare Advantage maintains a prescription drug list that tiers medications into cost-sharing tiers. For the 2026 plan year, Mounjaro is generally placed on Tier 4 (Specialty) on most Molina Medicare plan variants.
Cost implications:
- Cost-sharing: significant cost-sharing depending on coverage phase
- Prior authorization: Yes — a PA request is needed
- Quantity limits: Common — standard 30-day supply limits
- Step therapy: Might need trying first-line therapies first
The Medicare Part D coverage gap (donut hole), you’ll owe 25% of Mounjaro’s cost before catastrophic coverage applies.
Coverage for Different Indications
For type 2 diabetes (FDA-approved):
- Molina Medicare will generally authorize Mounjaro with appropriate documentation
- PA criteria: lab work and prescription history
- Coverage is more consistent when used on-label
For weight loss (where applicable):
- Traditional Medicare does not cover anti-obesity medications for weight loss alone
- An exception exists: 2025 policy changes may have changed Part D coverage eligibility for certain anti-obesity drugs
- Molina Medicare may offer additional drug benefits that include weight management medications — call Molina Healthcare member services
