What to do next
If you qualify under one of the covered indications above, prior authorization is the path. Match the documentation in the requirements list then have your prescriber submit it. Plans that approve reassess at renewal, so know your long-term maintenance dose before you start.
- Browse the prior-authorization letter library for a template that matches your plan and indication.
- Read the full coverage picture, denial reasons, and the four appeal pathways at GLP-1 insurance coverage.
- If the prior-authorization request is denied, the appeal letter library has templates by denial reason, covering peer-to-peer review, Level 1 and Level 2 internal appeal, and external review.
- If your plan does not cover the indication you need, compare cash prices in the cost guide or check whether a clinical trial near you fits. Neither one goes through your insurer. Clinical trials cost nothing and many pay you for your time. Some participants get a placebo, decided at random.

Frequently asked questions
Does Aetna cover Mounjaro?
Aetna covers Mounjaro for type 2 diabetes, but only with prior authorization. Its pharmacy policy approves the drug when a member has tried metformin without success, cannot take it, or needs combination therapy with an A1C of 7.5 percent or higher, and it applies quantity limits. Aetna will not cover Mounjaro for weight loss, because Mounjaro is FDA-approved for type 2 diabetes only. The weight-loss version of the same drug, tirzepatide, is sold as Zepbound and falls under a separate obesity benefit that an employer has to elect. This reflects the published policy verified August 2026.
What does Aetna require to approve Mounjaro?
For type 2 diabetes: true

How we built this page
Each page is built from a published payer policy document, government statute, or independent formulary analysis (KFF). Every indication row carries the source URL and the date we verified it. Where a payer's policy PDF was confirmed at its public URL but served as an unreadable binary, the policy number and coverage framework were cross-checked against secondary sources; those rows are marked lower confidence. Commercial coverage often depends on whether an employer elected the weight-management benefit. Those rows say varies by plan rather than a flat yes.
This is reference information, not medical or legal advice, and not a guarantee of coverage. GLP-1 coverage policies change often. Always confirm the current policy with your insurer using the number on your card before you rely on this page. If your experience differs from what is shown here, email hello@glpchart.com with the details and we will re-verify.
