OA-22: Coordination of Benefits - Another Payer May Cover
Adjustment in a COB or secondary payer context. Review the coordination of benefits details to determine the responsible party.
What Does OA-22 Mean?
With OA (Other Adjustments), CARC 22 typically appears in a coordination of benefits (COB) context. Claim requires coordination between multiple payers before processing. The financial responsibility depends on the specific arrangement between payers — review the primary payer's EOB and the COB terms to determine the correct course of action.
CARC 22 indicates coordination of benefits - another payer may cover. 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this adjustment include: claim submitted to the secondary payer without first billing the primary payer; The payer has outdated coordination of benefits data showing another primary payer; The claim is missing information about other insurance coverage the patient has. The group code paired with CARC 22 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.
