How to Write a Prior Auth Appeal Letter

A strong appeal letter can overturn a denial and get your patient the care they need. Here's what every effective appeal includes.

Reference the Denial Specifically

Include the authorization number, denial date, and the exact reason given. This helps the reviewer locate the case quickly and understand what you're contesting.

Provide Clinical Evidence

Document the patient's symptoms, examination findings, prior treatments tried, and why this specific procedure is the appropriate next step. Be specific and factual.

Cite Clinical Guidelines

Reference published medical guidelines, peer-reviewed studies, or specialty society recommendations that support the medical necessity of the requested procedure.

Submit Promptly

Most payers have strict deadlines for appeals, typically 30-180 days from the denial date. Check your payer's specific timeline and submit well before the deadline.

Prior Auth Appeal FAQs

How long do I have to file a prior authorization appeal?
Timelines vary by payer and state, but most commercial insurers allow 30 to 180 days from the date of the denial letter. Medicare Advantage plans typically allow 60 days for a standard appeal. Always check the denial letter for the specific deadline.
What is the difference between a first-level and second-level appeal?
A first-level appeal is your initial formal challenge to the denial, reviewed internally by the payer. If the first-level appeal is denied, you can file a second-level appeal, which is typically reviewed by an independent external reviewer not affiliated with the insurance company.
What documentation should I include with my appeal?
Include the original authorization request, the denial letter, clinical notes supporting medical necessity, relevant lab or imaging results, peer-reviewed literature or clinical guidelines, and any letters of support from other treating providers.
Can I request a peer-to-peer review instead of a written appeal?
Yes. Many payers offer peer-to-peer reviews where the ordering physician can speak directly with the payer's medical director. This can be faster than a written appeal and is often available before filing a formal appeal. Check your denial letter for instructions.
What are my options if my appeal is denied?
If your internal appeal is denied, you can request an external review by an independent third party. You may also file a complaint with your state's Department of Insurance. For Medicare patients, additional appeal levels are available through administrative law judges and the Medicare Appeals Council.
