Appeal letters that overturn prior authorization denials
Prior authorization is the paperwork physicians hate most — 75% say denials have increased over five years, and 61% worry payers' own AI is driving more of them. Writing the medical-necessity appeal is the bottleneck, and drafting it with AI turns a 30-45 minute letter into a 5-minute review, which is why both physicians and patient-advocacy tools have adopted it fastest.
You are a physician writing a medical-necessity appeal that a utilization reviewer can approve quickly. Draft an appeal letter for this denied service: {{treatment}}. De-identified clinical summary: {{clinical_summary}} The denial letter states: {{denial_reason}} Requirements: - One page maximum, professional and factual — no outrage, no pleading. - Open by identifying the service and requesting reconsideration, quote the denial language exactly, then rebut it point by point. - Use only the clinical facts I provided. Do not invent history, exam findings, lab values, or failed therapies. Where payer criteria typically require a fact I did not give you (documented step therapy, symptom duration, functional impairment), insert [NEED: description] so I can pull it from the chart. - Reference a clinical guideline only if I included it in the summary; otherwise write [CITATION: suggest a guideline for me to verify] instead of inventing one. - State the clinical consequence of further delay in one concrete sentence. - Close by requesting a peer-to-peer review with a same-specialty reviewer within the required timeframe. - After the letter, list the attachments this appeal should include.

I am writing to request reconsideration of the denial of continuous glucose monitoring for my patient. The denial states the service is "not medically necessary" because criteria require "documented hypoglycemia unawareness or A1c above goal despite adherence." Both criteria are in fact met. The patient's A1c is 9.2% despite documented adherence to a four-times-daily fingerstick regimen and three years of basal-bolus insulin therapy. Additionally, the patient has experienced two hypoglycemic episodes within six months, one requiring emergency department evaluation — [NEED: date range of episodes from chart]. I request a peer-to-peer review with a board-certified endocrinologist within the timeframe required under the plan's appeal process.
The full workflow
- Pull the exact denial language and the payer's stated criteria from the letter
- Write a de-identified clinical summary — strip names, dates of birth, MRNs, and exact dates
- Run the prompt and fill every [NEED] and [CITATION] flag from the chart and real guidelines
- Read the final letter against the chart before signing — every clinical claim must be documented
- Attach the supporting records and track the appeal deadline
Watch out for
HIPAA: never paste patient names, DOBs, MRNs, or exact dates into a consumer AI tool — OpenAI does not sign a BAA for standard ChatGPT accounts. De-identify first or use a BAA-covered tool.
Every clinical fact in the appeal must exist in the chart. An AI-embellished finding in a payer submission is a fraud exposure, and the signing physician — not the tool — is responsible.
Verify any guideline citation manually before sending; language models fabricate plausible-sounding references.
