Amputation surgery
About 27594: Thigh amputation stump revision
Revision surgery for an existing thigh-level amputation stump, reported when the surgeon modifies the residual limb rather than performing an initial amputation.
This service revises an existing amputation stump at the thigh or femur level. The surgeon may remove problematic tissue or bone and reshape the residual limb to address issues such as a painful bony prominence, tissue breakdown, or difficulty fitting a prosthesis. Orthopedic and vascular surgeons commonly perform this operation in a hospital or other surgical setting.
Report the code for revision of an established thigh-level stump, not for the original amputation. The operative note should identify the existing amputation level, the problem prompting revision, and the work performed on the residual limb. Medicare assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. 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 multiple procedure reduction. Bilateral reporting with modifier 50 is paid at 150%. Medicare does not pay an assistant at surgery for this code; co-surgeons and team surgery are not permitted.
