A denied prior authorization means the insurer refused to approve care before it happens — or denied a claim because authorization was never obtained. Both are appealable, and appealed prior-auth denials are frequently overturned once actual clinical documentation gets in front of a reviewer instead of a screening algorithm.

Two facts shape the fight. If your in-network provider failed to request authorization, that's generally the provider's process failure, not yours — and many plans bar billing you for it. And if the refusal was clinical ('not medically necessary,' 'step therapy required'), it's a judgment call your physician can rebut point by point. This guide covers both, with a complete template below.

First, identify which denial you have

Authorization never obtained: care happened, claim denied for missing prior auth. Your moves: ask the provider's billing office to file a retroactive authorization request (they have a financial stake in fixing it), and appeal on the basis that in-network authorization was the provider's responsibility. Note: emergency care cannot require prior authorization — federal law protects emergency screening and stabilization regardless.

Authorization requested and refused: this is a medical-necessity decision in different clothes. Get the specific criteria the reviewer applied (you're entitled to them), and have your physician answer each criterion with your clinical facts. For step-therapy refusals, document what was already tried and failed — or why the required first-step drug is contraindicated for you.

Deadlines run fast in your favor here: pre-service appeals must be decided quicker than post-service ones (generally within 30 days), and urgent cases qualify for expedited review measured in hours. Your own appeal window is at least 180 days on ACA plans — but go by your denial letter.

What to customize

Choose block A or B and delete the other — mixing them dilutes both.
The criteria rebuttal in block B — strongest when your physician has seen the insurer's actual criteria and answers them by name.
Step-therapy specifics — drugs, dates, outcomes, or the contraindication. Concrete beats general.
The expedited request — only when delay genuinely threatens health; your physician's office should note the urgency too.

Common mistakes that sink letters like this

Paying the bill and moving on when the provider skipped authorization — that failure is usually theirs to fix, not yours to fund.
Appealing a step-therapy denial without documenting the failed steps. Names, dates, and outcomes are the argument.
Missing that pre-service appeals get faster decision deadlines — cite the urgency and hold them to the clock.
Not requesting the reviewer's criteria and credentials. The answer often reveals a non-specialist applied a screening guideline.

Frequently asked questions

Can insurers require prior authorization for emergencies?

No. Federal law protects emergency screening and stabilization — insurers can't condition emergency coverage on prior authorization. Say plainly in your appeal that the care was emergency care.

Whose fault is a missing prior authorization?

For in-network care, the authorization obligation typically sits with the provider, and plan-provider contracts often bar billing you for the failure. Appeal on that basis and ask the provider to file a retroactive request in parallel.

How fast must the insurer decide my appeal?

Pre-service appeals: generally within 30 days. Expedited (urgent) appeals: as fast as 72 hours. Post-service: generally within 60 days. Your plan documents state the exact clocks.
