What 27138 covers
An orthopedic surgeon reports this service when revising the femoral component of an existing total hip replacement while leaving the acetabular component in place. The operation may address problems such as femoral component loosening or mechanical failure. It is typically performed in a hospital or other surgical facility; the revision may include use of an allograft. The key distinction is that the work revises the femoral component alone, rather than both sides of the joint or the acetabular component alone.
The operative report should identify the component revised and describe the revision performed, including any allograft use. Medicare assigns a 90-day global period, including 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 at 50%. Bilateral reporting with modifier 50 is paid at 150%. An assistant at surgery may be paid; co-surgeons are paid only with supporting documentation, and team surgery is not permitted.
