What 27140 covers
An orthopedic surgeon detaches and relocates the greater trochanter, the bony prominence where important hip muscles attach. The operation is associated with reconstructive treatment of hip deformity, including selected cases of congenital hip dislocation, when repositioning the trochanter can improve the abductor mechanism. It is generally performed in an operating room rather than an office setting.
Select this code when the operative report supports transplantation of the greater trochanter, rather than a muscle transfer or a different hip-bone reconstruction. Document the indication, operative side, detachment and new position of the trochanter, and any fixation performed. The service has a 90-day global period that includes the day-before preoperative visit and 90 days of 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.
