Precertification/Authorization Exceeded

What it means

The payer approved an authorization for a certain number of visits, units, or days, but the services billed went beyond what was authorized. This denial means the care provided exceeded the limits set in the original precertification.

Common causes

More units, visits, or days of service were rendered than the authorization permitted
Treatment continued past the authorized date range
Clinical staff were unaware of the exact limits approved on the authorization
No request was made to extend or expand the authorization before additional services were provided
Authorization was approved for a different quantity than what was actually needed for the full course of treatment

How to fix it

Pull the original authorization and confirm the exact number of approved units, visits, or days
Compare the authorized amount to what was actually billed to identify the overage
Contact the payer to request a retroactive authorization extension if clinically justified
Submit supporting clinical documentation showing medical necessity for the additional services
If the authorization number was incorrect or outdated, correct it and resubmit the claim
Establish an internal process to track authorization limits in real time during treatment to prevent future overages

Appeal / resubmit

When appealing, include detailed clinical notes and progress reports that justify why care extended beyond the originally authorized amount. If an extension request was submitted but not acted on timely by the payer, document that timeline. Reference the payer's specific policy on retroactive or extended authorizations, as some payers allow after-the-fact approval when medical necessity is clearly supported.

Frequently asked

Does this mean the whole claim is denied?

Not always. Often only the units or visits beyond the authorized limit are denied, while the portion within the approved amount may still be paid.

Can I get the extra services paid after the fact?

Some payers allow retroactive authorization extensions with proper clinical justification, but this depends on the payer's specific policies and timelines.

How can I prevent this denial in the future?

Track authorization limits closely during the course of treatment and request extensions proactively before the approved amount is reached.
