Appeal letter generator.

A generic appeal loses. This builds a letter that addresses the specific ground your claim was denied on, requests the documents you are entitled to, and names the escalation path for your plan type.

Nothing you type is stored or transmitted. The letter is built in your browser. Copy it, edit it, and send it yourself.
Before you send it. This is a starting draft, not legal advice. Check the deadline and the mailing address on your own denial notice — they govern over anything here. For a medical necessity denial, the letter is only as strong as the letter of medical necessity your provider encloses with it.

What makes an appeal work

Reviewers are comparing documentation against written criteria. An appeal that argues in general terms about hardship rarely moves that comparison. An appeal that names the criterion, addresses it directly, and encloses the record that satisfies it does.

Three requests in this letter matter as much as the argument: the clinical criteria applied, the reviewer's credentials, and review by a physician in the same specialty. All three are routinely available on request and rarely asked for.

If the internal appeal fails

Internal appeal is reviewed by the insurer. External review goes to an independent third party whose decision binds the plan, and you generally must exhaust the internal appeal first. Which external process applies depends on your plan type — see appeal rights by state.
