Typical Clinical Scenarios

A 28-year-old construction worker presents after a traumatic degloving injury to the left forearm and wrist with loss of key wrist flexor muscle function and exposed tendon. He is admitted for acute surgical reconstruction to restore wrist flexion by transferring a nearby viable left lower arm muscle and, because of the open wound, the surgeon includes skin coverage during the transfer using an open approach. Typical codes: 0KXB0Z0, 0KXB0Z2
A 62-year-old woman with chronic radial nerve palsy and progressive loss of wrist and finger extension undergoes an elective inpatient tendon and muscle transfer procedure to reanimate wrist extension; the planned operation is performed endoscopically to minimize soft-tissue dissection and the surgeon transfers muscle tissue without adding a device. Typical codes: 0KXB4ZZ, 0KXB4Z1
A 45-year-old patient with a prior failed left wrist muscle transfer presents with weakness and scar contracture requiring revision transfer and release; during the inpatient revision the surgeon performs an open transfer of muscle and releases scarred subcutaneous tissue to restore function. Typical codes: 0KXB0Z1, 0KXB0ZZ
