What actually happens after a denial

A denial is one reviewer's decision, and the rules that follow it are federal. Most people stop at the first stage below, which is the stage the insurer decides. The stage after that is decided by someone else entirely.

StageYour deadlineWho decides
Internal appealAt least 180 days from the denial noticeThe plan, but a reviewer who was not part of the first decision
Expedited appealDecision due in about 72 hours, if you ask for itThe plan, on an urgent track
External reviewGenerally 4 months after the final internal denial, decided in about 45 daysAn independent organisation. Its decision binds the plan

Sources: 29 CFR 2560.503-1(h)(3)(i), the 180-day appeal window; 45 CFR 147.136(d), external review by an independent organisation; HealthCare.gov, how to appeal an insurance company decision. Your plan documents and your denial notice govern your case, and Medicare, Medicaid and some older grandfathered plans run different processes.

Questions people ask after a denial

How long do I have to appeal an insurance denial?

Federal rules give you at least 180 days from the date of the denial notice to file an internal appeal. Your own plan documents and the notice itself govern your case, so read the deadline printed on the letter. Filing early is better than filing late, because a missed deadline ends the appeal regardless of how strong it was.

What happens if the insurance company denies my appeal again?

You can request an independent external review, generally within 4 months of the final internal denial. An outside organisation reviews the claim fresh rather than checking the insurer's work, usually decides within about 45 days, and its decision binds the plan. That last part is the reason external review matters: the insurer does not get to overrule it.

Does an insurance company have to tell me why they denied my claim?

Yes. You are entitled to the specific reason for the denial, the plan provision or clinical criteria it relied on, and copies of the documents and internal rules used to decide your claim, in writing and free of charge. Asking for these in the appeal is worth doing even when you think you know the reason, because the written criteria often name a requirement the denial letter never mentioned.

Can I get a faster decision if waiting would hurt me?

Yes. If a delay would seriously jeopardise your health or your ability to regain maximum function, you can request an expedited appeal, on which a decision is generally due within 72 hours. You have to ask for it. The appeal letter on every page here includes that request.

Do I need a lawyer to appeal a denial?

No. The internal appeal and the external review are both processes you file yourself, in writing, with no lawyer and no filing fee. Most denials that get overturned are overturned on paperwork rather than argument, meaning the plan wanted a document or a diagnosis code that was never in the file.

Is the appeal letter on these pages really free?

Yes. Every denial page here prints a complete appeal letter you can copy or download at no cost, with no account. What we charge for is the version written against the specific reason printed on your own denial notice, with your codes, dates and amounts in it.
