Orthopedic surgery
About 27596: Thigh amputation stump reoperation
Reports repeat surgery at a prior thigh-level amputation site when the femoral stump requires re-amputation, secondary closure, or scar revision.
This code describes repeat surgery on a previous amputation through the thigh, such as re-amputating the femoral stump or addressing the site with secondary closure or scar revision. It may be performed when a prior stump needs further operative treatment, including for nonhealing tissue or a wound problem. Orthopedic or vascular surgeons typically perform the procedure in a hospital operating room or another surgical facility.
Select this code for the documented thigh-level reoperation, not for the original amputation. The operative report should establish the prior amputation, the level and extent of the new work, and whether the procedure involved re-amputation, secondary closure, or scar revision. Medicare assigns a 90-day major-surgery global period; the day-before preoperative visit and 90 days of related postoperative care are included. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and others at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment is statutorily restricted; co-surgeons are paid only with supporting documentation, and team surgery is not permitted.
