About 27538: Closed treatment of tibial spine or tubercle fracture
Reports closed treatment without manipulation of a knee fracture involving the tibial intercondylar spine or tibial tuberosity.
Code 27538 covers closed management of a fracture involving the tibial intercondylar spine, also called the tibial eminence, or the tibial tuberosity. A common example is a tibial spine avulsion fracture managed without operative exposure or manipulation. An orthopedic or trauma surgeon may provide the treatment in a hospital, outpatient facility, or office setting, using immobilization such as a brace or cast as appropriate.
Select this code when the documented fracture site and treatment match those criteria; distinguish it from tibial plateau, patellar, and open-treatment codes. The record should identify the fracture location and closed plan without manipulation. CMS assigns a 90-day global period, including the day-before preoperative visit and related postoperative care. When multiple procedures occur in one session, the highest-valued procedure is paid in full and others at 50%. For bilateral treatment reported with modifier 50, CMS pays 150%. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.
