Turning "Denied" Into "Covered" — The Insurance Appeal Playbook

Most people who get a denial letter stop right there — which is exactly what the system counts on. A denial is the start of a process, not the end of one. You have a federal right to appeal, many denials are administrative and very winnable, and this is the playbook.

First: get the specific reason in writing

Common denial reasons — note how many are paperwork, not medicine:

• "Not medically necessary" — answerable with your doctor's documentation
• Prior authorization wasn't obtained — administrative, very winnable
• A coding or paperwork error — administrative, very winnable
• Out-of-network — may be a No Surprises Act violation
• Missing information — administrative, very winnable

Your two-level federal right

1. Internal appeal — the insurer reconsiders. Always the first step.
2. External review — an independent third party with no stake in saying no. Their decision is binding on the plan. Don't stop at the internal appeal if you believe you're right — this is your ace.

Both levels can be expedited for urgent situations. This two-step right comes from the ACA's consumer protections — confirm at healthcare.gov.

Protect the deadline, then build the file

• Find the appeal deadline the moment the denial arrives. The #1 reason appeals fail is a missed deadline — everything else is recoverable.
• Gather: the denial letter, your plan documents, the relevant medical records, and a letter of medical necessity from your doctor.
• Get the doctor's office involved — they can supply documentation and often want to help. Also request a peer-to-peer review (your doctor speaks to the insurer's doctor) — it resolves many denials before the formal appeal finishes.
• Keep a paper trail: every call, name, date, and reference number.

The five parts of an appeal that wins

1. Identify the claim — names, member ID, claim/denial number, date.
2. State what you want — "I am appealing the denial of [service] and requesting it be covered."
3. Answer the stated reason directly — if it's "not medically necessary," show why it is, with your doctor's support.
4. Attach the proof — records, the medical-necessity letter, the policy language that supports you. A document for every claim.
5. Request a written decision by the deadline — and keep copies of everything.

Free help exists

Your state insurance department's consumer assistance program handles appeals. SHIP counselors help with Medicare appeals, free, in every state. Your doctor's office and the hospital billing office can assist. For large or complex denials, an independent patient advocate can run the whole process with you.

"Denied" is a door, not a wall — and the system bets you won't push it open.
