What CO 24 actually means

The payer says this care is inside a capitated arrangement — either the patient is in a Medicare/Medicaid managed-care plan you billed FFS, or your group holds a cap contract that already “paid” for this service.

Liability group: CO = Contractual Obligation — the provider absorbs it — the amount cannot be billed to the patient. If the denial is wrong, the money is recovered by correcting or appealing the claim, not by balance-billing.

Why CO 24 fires

How to fix CO 24

1

Step 1

Check eligibility for plan type and IPA assignment on the DOS

2

Step 2

If MA/MCO member: bill that plan (new timely-filing clock usually applies)

3

Step 3

If capitated: confirm the CPT is actually inside the cap — many aren't

4

Step 4

Non-cap services denied as cap: dispute with the contract's division-of-financial-responsibility (DOFR) matrix

How to appeal it

Appealable when the service falls OUTSIDE the capitation: attach the DOFR/contract exhibit showing the CPT is FFS-payable and demand adjudication. Pure cap services are write-offs.
