How do I appeal a denied insurance claim?

Request the denial reason in writing, gather supporting medical records or documents, cite your policy coverage terms, and submit a formal appeal within the deadline.

What is the deadline to appeal an insurance denial?

Most insurers give 30-180 days to appeal. Check your denial letter for the exact deadline. Missing it can forfeit your right to appeal, so act quickly.

How often are insurance appeals successful?

About 50% of appealed claims are overturned. Including a letter of medical necessity from your doctor and citing specific policy language significantly increases your chances.
