What Does OA-54 Mean?

With OA (Other Adjustments), CARC 54 typically appears in a coordination of benefits (COB) context. Secondary payer denies multiple provider charges. 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 54 indicates multiple physicians/assistants not covered. 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: payer determined that multiple surgeons or surgical assistants were not justified for the case; The payer does not cover assistant surgeon services for this procedure; Multiple physicians treating the same condition simultaneously without documented necessity. The group code paired with CARC 54 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.
