Prior authorization checklist
- Diagnosis: Your chart shows either type 2 diabetes or heart risk as an approved use of Mounjaro.
- Records: Include recent A1C results, along with diabetes drugs you have tried before.
- Who submits it: Your prescriber, not you, files the prior authorization.
The appeal: if you are denied
| Denial reason | What to send or ask |
|---|---|
| Prior authorization missing | Your prescriber sends recent A1C results and your type 2 diabetes diagnosis using the plan's form. |
| The plan wants another drug first | Send the plan records of drugs already tried, and ask which drugs it wants you to try first. |
| The drug is not on the plan's list | Find out which GLP-1 the plan prefers, and ask them for a formulary exception. |
- Get the denial letter, since it shows the exact rule that was not met.
- Your prescriber sends in the appeal along with chart notes that address that rule.
- Should the plan's appeal fail, ask for an external review by an independent reviewer.
