Coverage at a glance
| Indication | Coverage |
|---|---|
| Type 2 diabetes | Covered with prior authorization |
Plan type: Commercial non-Medicare. Each indication below lists the BMI and clinical thresholds, the prior-authorization documentation, and the published policy it comes from.
This varies by plan. Kaiser is an integrated HMO, and its formulary and cost tier vary by region. Coverage of Mounjaro for type 2 diabetes is a standard pharmacy benefit subject to prior authorization and step therapy, not an employer rider. Coverage of GLP-1 drugs for weight loss (Zepbound is the tirzepatide) is separate and applies only when the employer plan buys that benefit.
Coverage by indication
| Step therapy |
What the prior authorization needs:
- Prior authorization through Kaiser's Criteria-Based Consultation Prescribing Program (Mounjaro is non-formulary but coverable when criteria are met).
- Diagnosis of type 2 diabetes.
- No personal or family history of medullary thyroid carcinoma (MTC) or multiple endocrine neoplasia syndrome type 2 (MEN 2).
- On or has failed maximum-tolerated semaglutide (2 mg once weekly) for at least 3 months, or has a contraindication or intolerance to semaglutide.
- On or intolerant to maximally tolerated metformin, a sulfonylurea, pioglitazone, and an SGLT2 inhibitor.
- A1C (or GMI) still above 6.9% and below 10% after an adequate trial (about 3 months) of the therapies above.

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.
- Call the number on your insurance card and ask whether your specific plan includes the weight-management drug benefit before you submit.
- 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 Kaiser cover Mounjaro?
Kaiser Permanente covers Mounjaro for type 2 diabetes, but only through prior authorization with extensive step therapy. Kaiser's published Northwest criteria require patients to be on or to have failed maximum-tolerated semaglutide (2 mg weekly for at least 3 months) plus metformin, a sulfonylurea, pioglitazone, and an SGLT2 inhibitor, with A1C still above 6.9%. Mounjaro is FDA-approved for type 2 diabetes only, so Kaiser will not cover it for weight loss. The weight-loss tirzepatide is Zepbound, which Kaiser covers only when the employer plan buys a weight-loss drug benefit. This reflects the published policy verified August 2026.

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.
