What 25430 covers
A hand or wrist surgeon transfers bone with its blood supply to a carpal bone. A common clinical setting is a scaphoid nonunion with impaired blood supply; the operative report should identify the carpal bone treated and explain the reason for using a vascularized graft. These procedures are generally performed in a hospital operating room.
Select this code when the documented operation places a vascularized graft into a carpal bone, rather than using a nonvascularized repair approach or treating the radius or ulna. Document the graft transfer, treated site, indication, and any fixation performed. Medicare assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 indicates bilateral performance and is paid at 150%. Assistant-at-surgery payment is restricted; co-surgeons and team surgery are not permitted.
