CO-24: Charges Covered Under Capitation

CO-24 means the payer considers this service already paid for under a capitation or managed-care arrangement, so it won't pay fee-for-service on top. Sometimes correct — sometimes the patient wasn't actually capitated to your group.

Official (X12/WPC): "Charges are covered under a capitation agreement/managed care plan."

Why payers issue CO-24

The patient is assigned to a capitated group and the service falls under the cap
The patient's capitation assignment on file is wrong or outdated
A carve-out service that should be paid FFS was treated as capitated
The claim went to the wrong entity within a delegated arrangement

Is it recoverable? Recoverable when the patient wasn't truly capitated to you, or the service is a fee-for-service carve-out the cap doesn't cover — verify the assignment before writing it off.

Common questions

What does CO-24 mean?

Recoverable when the patient wasn't truly capitated to you, or the service is a fee-for-service carve-out the cap doesn't cover — verify the assignment before writing it off.

Is a CO-24 denial worth appealing?

Recoverable when the patient wasn't truly capitated to you, or the service is a fee-for-service carve-out the cap doesn't cover — verify the assignment before writing it off. You only pay on what's actually recovered, so there's no cost to working the ones that are winnable.
