CO-94: Processed in Excess of Charges

What Does CO-94 Mean?

With CO (Contractual Obligation), the CARC 94 adjustment for processed in excess of charges is a contractual reduction. The provider absorbs this amount per the payer contract or regulatory payment methodology. The patient is not responsible for the adjusted amount. Review the remittance to confirm the adjustment is consistent with your contract terms.

CARC 94 means the payer adjusted the payment based on processed in excess of charges. The reimbursement was calculated using the payer's fee schedule, contracted rate, or regulatory payment methodology rather than the billed charge.

Common scenarios that trigger this adjustment include: the payer's fee schedule or contractual rate for the service is higher than the amount the provider billed. The payer adjusts the payment down to the billed charge amount, since payment cannot exceed what was billed; The provider's charge master has rates set below the payer's allowable amount for certain services, creating a situation where the calculated payment exceeds the billed amount; The contracted rate negotiated with the payer exceeds the amount actually billed on the claim for a specific service. The group code paired with CARC 94 determines who bears the financial responsibility — CO places it on the provider as a contractual obligation, OA indicates a coordination of benefits or other payer adjustment, PR shifts it to the patient.

Common Causes

How to Resolve

1. Review the adjustment against contract terms Compare the CO-94 adjustment with your payer contract to confirm the reduction is consistent with agreed terms or regulatory methodology.
2. Verify the adjustment amount Confirm the dollar amount of the adjustment is calculated correctly based on the contracted rate and the service provided.
3. Process the contractual adjustment If the adjustment is correct per contract terms, process it accordingly in your billing system. This amount cannot be transferred to the patient.

How to Prevent CO-94

• Conduct annual charge master reviews to ensure all charges meet or exceed payer fee schedule rates
• Compare charge master rates against Medicare, Medicaid, and commercial payer fee schedules regularly
• Implement charge capture validation that flags billed amounts below known payer allowable rates
• Set charge master prices at a minimum of 200-300% of Medicare rates to avoid leaving reimbursement on the table
• Review CARC 94 occurrences quarterly to identify services that need charge master updates
