Roughly half of appealed denials get overturned, and most people never appeal at all. Answer a few questions and you'll have a formal letter you can print and send. Nothing you type here is saved or sent anywhere — it stays in your browser.
This tool produces a template letter for your own use. It is educational support, not legal or medical advice, and it doesn't guarantee any outcome. If your appeal is denied again, ask your plan in writing for external review instructions, and consider contacting your state insurance commissioner.
