How to Appeal a Specialty or Prescription Drug Denial
Denied a prescription drug for "prior authorization" or "not medically necessary"? A well-documented medical-necessity appeal overturns many of these.
Your deadline: most plans allow 180 days from the date on your denial letter to file an internal appeal — more time than most people think. Check the date on your letter.
Why specialty or prescription drug claims get denied
- Prior authorization criteria not met or not documented
- Step therapy — try a cheaper drug first
- "Not medically necessary" or "experimental/investigational"
The argument that wins
- Build a medical-necessity case tied to clinical guidelines and your diagnosis, with a prescriber attestation — prescriber documentation is what decides most drug appeals.
- Request a step-therapy exception if you have already tried and failed the required alternatives, or have a documented reason they are inappropriate.
- For "experimental" denials, cite FDA approval for your indication and peer-reviewed evidence supporting the treatment.
Evidence to gather
- Your diagnosis and relevant clinical records
- A record of prior drugs tried and their outcomes
- A letter of medical necessity from your prescriber citing guidelines

What does "prior authorization denied" mean?
The plan requires approval before covering the drug and determined the criteria were not met or not documented. Submitting the missing clinical documentation on appeal often resolves it.
How do I beat a step-therapy requirement?
Request a step-therapy exception, showing you already tried the required alternatives, or that they are contraindicated or clinically inappropriate for you.
