How Prior Authorization Windows Work

When an insurer approves a prior authorization request, they issue an authorization number and specify a validity period. Common windows are 30, 60, or 90 days â€” though some plans authorize up to 180 days for certain services and others as few as 30 days for imaging or procedures.

The authorization is valid only for the specific service, the specific provider, and the specific window specified. If any of those elements change, or if the service occurs after the window closes, the authorization may be void.

A prior authorization approval does not guarantee payment. It guarantees that the insurer reviewed the request and determined coverage was appropriate, subject to the terms of the authorization. If the service occurs outside those terms, the claim can still be denied.

Why Authorizations Expire Before Treatment

Specialist appointment backlogs push the surgery or procedure date past the authorization window

A patient's condition requires additional workup before treatment, consuming the authorization window

A hospital facility date changes for scheduling or staffing reasons

Insurance changes between authorization and treatment â€” job change, open enrollment, Medicare transition

A prior authorization was approved well in advance but the actual treatment is months away

A proactive provider obtained the authorization early, but the provider did not schedule in time

What You Can Do

STEP 01

Know Your Authorization Expiration Date

Ask for the expiration date when you receive an authorization. Write it down. It should appear in the authorization letter or confirmation your provider receives. If your scheduled appointment or procedure date is close to the expiration, bring it up with your provider's office immediately.

STEP 02

Renew Before It Expires

If you know your treatment will occur after the authorization expires, ask your provider's office to request a renewal or extension before the current authorization runs out. Renewing in advance is significantly easier than appealing a denied claim after the fact. Insurers generally require the same clinical documentation for a renewal as for the original authorization.

STEP 03

Request Retroactive Authorization If the Window Has Closed

If the service has already occurred and the authorization has lapsed, ask your provider to request retroactive authorization from the insurer. Retroactive authorization is not guaranteed, but many insurers will grant it when the delay was caused by circumstances outside the patient's control, when the clinical documentation still supports the authorization, and when the request is made promptly after the denial.

STEP 04

Appeal a Denial for Expired Authorization

If retroactive authorization is denied, the claim denial can be appealed. The appeal should explain why the service occurred outside the authorization window and provide documentation supporting medical necessity. If the delay was caused by the insurer's own processes, administrative backlog, or factors outside your control, say so explicitly in the appeal.

If your insurer required a specific process that delayed your treatment past your authorization window, document that timeline. A denial caused by an insurer-created delay is a strong appeal. The insurer cannot benefit from a delay they caused.

Track Authorization Status Proactively

If you are managing a treatment plan involving multiple services or staged treatment over time, track each authorization separately. Confirm the authorization number, approval date, expiration date, and authorized service each time your provider obtains an approval.
