CO-119: Benefit Maximum Reached

What Does CO-119 Mean?

With CO (Contractual Obligation), the CARC 119 adjustment for benefit maximum reached 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 119 indicates benefit maximum reached. The payer determined that the service or a portion of it does not meet coverage criteria under the patient's current plan benefits or the applicable coverage rules.

Common scenarios that trigger this adjustment include: the patient's plan has an annual or lifetime dollar maximum for the service category, and the total claims have reached that limit; The patient has used the maximum number of covered visits or treatments for the service type (e.g., 60 physical therapy visits per year), and additional services are not covered; The patient has exhausted their covered days for a specific benefit (e.g., inpatient psychiatric days, SNF days). The group code paired with CARC 119 determines who bears the financial responsibility — CO places it on the provider as a contractual obligation, PR shifts it to the patient, OA indicates a coordination of benefits or other payer adjustment.

Common Causes

How to Resolve

1. Review the adjustment against contract terms Compare the CO-119 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. Appeal if the adjustment is incorrect Appeal if the benefit accumulator appears incorrect or if a medical necessity exception applies. Include documentation of actual benefit utilization, medical necessity for continued treatment, and any applicable exception criteria (e.g., KX modifier for Medicare therapy cap exceptions). For Medicare, file within 120 days.
4. 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-119

• Verify remaining benefits before each service to identify patients approaching their maximum
• Track benefit accumulations by service category for all patients
• Inform patients when they are nearing their benefit maximum and discuss options
• For Medicare therapy services, submit the KX modifier when medical necessity supports services above the therapy threshold
• Obtain ABN or financial responsibility acknowledgment from patients before providing services once the maximum is reached
