Write an appeal letter before the deadline on your denial notice: quote the claim number, policy number, and dates of service, state exactly why the denial was wrong, and attach copies of supporting records. Keep the denial letter, mail your appeal with tracking, and note that many denials are overturned once a human re-reviews the file.
The denial notice tells you the reason code, the deadline, and where to send the appeal: read all three before writing a word. Deadlines are strict and often shorter than people expect; employer-sponsored health plans commonly allow 180 days for an internal appeal, but individual policies and other claim types vary. Miss the deadline and the denial stands regardless of its merits. Circle the reason code, because your entire appeal is an argument against that specific reason, not a general complaint about the insurer.
| Section | What to write |
|---|---|
| Identification | Your name, policy number, claim number, and dates of service |
| The denial, quoted | The reason code and wording from the denial notice, so the reviewer knows exactly what you are contesting |
| Why it is wrong | One clear argument per paragraph: the service was medically necessary, the code was misread, the policy covers it |
| The policy language | Quote the section of your policy that covers the service back at them |
| Supporting records | Copies of the doctor's letter of medical necessity, clinical notes, and test results |
| The ask | "I request that you overturn the denial and pay claim #___" with a response deadline |
A letter of medical necessity from your doctor is the single strongest enclosure: it translates your situation into the clinical language reviewers use. Clinical notes and test results back it up. And do not skip the policy-language step: quoting the insurer's own coverage wording turns the appeal from "please reconsider" into "your own contract covers this," which is a much harder letter to deny twice. Send copies of everything and keep the originals; the file you build now is the same file an external reviewer or regulator will read later.
You usually have a second level: an external review by an independent third party, available for most health plans in every state. The external reviewer is not employed by your insurer, and their decision is typically binding on the company. You can also complain to your state insurance commissioner, whose office tracks complaint patterns and can pressure insurers on mishandled claims. Throughout, keep every letter, every tracking receipt, and a log of every phone call with names and dates.
The letter itself, yes: describe it to your AI assistant, approve the exact quoted price, and it is printed and mailed with tracking through the registered option. But an appeal is only as strong as its enclosures, and LetterAgent mails letters only, no inserts, so your doctor's letter and records copies need to travel separately. For a document-heavy appeal, assembling the packet yourself keeps everything together; use LetterAgent when the letter alone carries the argument.
