What 25929 covers
This code describes surgery to revise a residual hand after an amputation through the metacarpals. A hand or orthopedic surgeon may reshape the remaining bone and soft tissue or address a problematic scar or wound when the residual limb is painful, poorly healed, or unsuitable for use. The operative report should establish that this is revision of a prior amputation and document the level and work performed.
Report the code for the revision procedure, not for the original amputation. It has a 90-day global period, which includes the day-before preoperative visit and related postoperative care during that period. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple procedure reduction. Modifier 50 applies to bilateral procedures, with payment at 150%. An assistant at surgery may be paid; co-surgeons and team surgery are not permitted.
