The day your insurance claim gets denied, and what to do in the first 48 hours

A denial letter is written to sound final. It rarely is. Insurers deny a meaningful share of claims on the first pass — sometimes correctly, often on a technicality, a missing document, or a coding error that has nothing to do with whether the underlying claim is valid. The letter is the opening move of a process that has an appeal built into it by law in most states; treating it as the last word is the single most common way people leave money they’re owed on the table.

Read the denial reason, not just the denial

Every denial letter states a reason code or category — policy exclusion, lack of medical necessity, missing documentation, filed after the deadline, and so on. That reason determines your entire appeal strategy. An appeal that doesn’t address the actual stated reason, however well-written, doesn’t move the outcome. This is the first thing to identify, before drafting a single word of response.

The clock started when you didn’t notice

Appeal windows are real and usually shorter than people expect — often 60 to 180 days depending on the policy and jurisdiction, sometimes less for certain claim types. The window is printed on the denial letter itself; that number, not a general assumption, is the one that governs. Missing it can forfeit the right to appeal entirely, regardless of how strong the underlying claim is.

Documentation wins appeals

A strong appeal is built on paper: the original policy language, the denial letter, medical records or repair estimates, and anything showing the claim meets the terms the denial says it doesn’t. Insurers are required to explain their reasoning in writing — use that requirement. Ask, in writing, for the specific policy provision and claims-file documentation behind the denial if the letter doesn’t already spell it out; you’re entitled to see the basis for the decision you’re appealing.

Escalation exists for a reason

If an internal appeal doesn’t resolve it, most states have a Department of Insurance that handles consumer complaints, and many policies are also subject to external review by an independent reviewer outside the insurer entirely. These aren’t last resorts to be embarrassed about using — they exist specifically because internal appeals don’t always work, and insurers know a documented complaint on file changes their calculation.

How to use this

Insurance Claim Coach reads your specific denial — auto, home, health, or disability — and maps the appeal: the language to use, the documents the insurer is required to have on file, the deadline that actually binds for your policy, and the bad-faith patterns worth flagging if the same insurer keeps finding new reasons to deny. It doesn’t replace an attorney for a claim large enough to warrant one, and it says so plainly.
