What Does OA-74 Mean?

With OA (Other Adjustments), CARC 74 typically appears in a coordination of benefits (COB) context. In multi-payer situations, the primary payer's IME adjustment passes to the secondary payer under OA. 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 74 means the payer adjusted the payment based on indirect medical education adjustment. 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: teaching hospitals receive an IME add-on payment as part of Medicare's inpatient PPS. CARC 74 reflects the adjustment between billed charges and the IME-adjusted payment amount, which is a normal part of the Medicare payment calculation; The hospital's reported intern-and-resident-to-bed (IRB) ratio used in the IME calculation was inaccurate, resulting in a different adjustment amount than expected; Required documentation supporting the hospital's teaching status, resident counts, or accreditation was not submitted or was incomplete, leading to an incorrect IME adjustment. The group code paired with CARC 74 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.
