About 24935: Upper-arm amputation revision
Revision of an existing upper-arm amputation reshapes the residual limb when surgical correction is needed for problems such as a prominent bone or poor prosthetic fit.
This operation revises an existing upper-arm amputation stump rather than removing the arm for the first time. The surgeon may reshape the residual limb’s bone or soft tissue to address a problem such as a painful prominence, impaired healing, or difficulty fitting a prosthesis. Orthopedic and other surgeons who manage limb loss may perform the procedure in an operating room, commonly in a hospital or ambulatory surgical setting.
Report the code when the operative service is a revision of an existing upper-arm amputation; document the prior amputation, the reason for revision, and the work performed on the residual limb. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in the same session, the highest-valued procedure is paid in full and other procedures are paid at 50%. For bilateral reporting with modifier 50, payment is at 150%. Assistant-at-surgery payment requires documentation of medical necessity; co-surgeons and team surgery are not permitted.
