Under general anesthesia, a 45-year-old patient was sterilely prepped. The wrist joint was injected with Marcaine and epinephrine. Three arthroscopic portals were created. The articulating surface between the scaphoid and the lunate clearly showed disruption of the ligamentous structures. We could see soft tissue pouching out into the joint; this was debrided. There was abnormal motion noted within the scapholunate articulation. At this point the C-arm was brought in. Arthroscopic instruments were placed in the joint and confirmed the location of the shaver as a probe in the scapholunate ligament. There was a significant gap between the capitate and lunate. K-wire was utilized from the dorsal surface into the lunate, restoring the space. Further examination revealed gross instability between the capitate and lunate. With the wrist in neutral position, a K-wire was passed through the scaphoid, through the capitate and into the hamate. This provided stabilization of the wrist joint. Stitches were placed, and a thumb spica cast was applied. What CPT® code(s) is/are reported?
