What Does OA-232 Mean?

With OA, the transfer adjustment appeared during coordination of benefits.

CARC 232 is specific to inpatient institutional claims where the patient was transferred from one facility to another during the inpatient stay. Under Medicare's transfer policy, when a patient is transferred before the full episode of care is complete, the transferring hospital receives a per diem payment rather than the full DRG amount. The per diem rate is calculated based on the DRG payment divided by the geometric mean length of stay.

This adjustment ensures the transferring hospital is paid proportionally for the portion of the inpatient stay they provided, rather than receiving the full DRG payment for an incomplete stay.
