What 27881 covers

This service combines removal of the lower leg below the knee with immediate prosthetic fitting and application of the first cast. It is generally performed in an operating room by an orthopedic, vascular, or trauma surgeon when the lower leg is nonviable or unsalvageable, such as with critical ischemia, severe infection, or major injury. The defining feature is immediate fitting at the operative episode, not simply the amputation level.

Report 27881 when the operative record supports both the amputation and immediate prosthetic fitting with the first cast; without immediate fitting, 27880 is the closer code. The 90-day global includes the day-before preoperative visit and related postoperative care. For multiple procedures in one session, the highest-valued procedure is paid in full and other procedures at 50%. Bilateral reporting with modifier 50 is paid at 150%. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
