Industry chatter puts first-pass GLP-1 denial rates roughly in the 30–50% range depending on plan and indication. Appeals work when you answer the exact reason code with chart evidence — not when you resubmit the same sparse note. You usually have about 180 days from the denial to start an internal appeal; external review deadlines are state-dependent.
Five-step appeal workflow
- 1. Extract the reason code and drug (wrong brand denials are common — Mounjaro vs Zepbound)
- 2. Download the plan medical policy / clinical criteria PDF
- 3. Map each criterion to a chart document (BMI series, comorbidity, step therapy)
- 4. Prescriber peer-to-peer + written medical necessity citing the policy
- 5. Internal appeal → external review if needed
Evidence that moves reviewers
Template letters that ignore the plan’s wording underperform. Quote the policy section numbers in the appeal cover letter.
- Serial BMI or weight logs across visits
- OSA / HTN / PCOS / lipid diagnoses tied to obesity
- Metformin intolerance (GI) or contraindication notes — step therapy
- Failed or partial response to older agents when required
Paying during the appeal window
Options: samples, short cash fills, or compounded bridge if clinically appropriate — each has tradeoffs. Manufacturer GLP-1 savings cards only help if you already have commercial coverage and a payable claim. Estimate burn rate with Truth Checker.

Frequently Asked Questions
How long do GLP-1 appeals take?
Internal reviews often 30–60 days; external review can add roughly 45 days depending on state rules.
Should I switch brands instead of appealing?
If the denial is “wrong NDC for indication,” switching to the covered brand (e.g. Zepbound vs Mounjaro) can be faster than appealing the wrong product.
