How to Write an Appeal Letter in the US
Whether you are appealing an insurance denial, a government benefits decision, or another administrative ruling — this guide explains the process and how to make the strongest case.
Appealing an insurance claim denial
- —Request your complete claim file and the specific policy provisions cited
- —Write a formal appeal addressing each denial ground with supporting evidence
- —For health insurance, include a letter from your treating physician
- —For property claims, obtain independent repair or replacement estimates
- —Reference the insurer’s duty of good faith and fair dealing
Health insurance external appeals
Under the ACA, you have the right to external review of coverage denials by an independent organisation. Request after exhausting internal appeals. The external reviewer’s decision is binding on the insurer.

- —Stage 4: Federal district court
Veterans benefits appeals

Deadlines are strict — typically 10-30 days from the denial notice. The appeal involves a phone or in-person hearing before an appeals referee. You can present evidence and question the employer’s witnesses.
