About 27416: Open knee osteochondral autograft
Open transfer of a patient’s own osteochondral tissue treats a focal knee defect when healthy cartilage and underlying bone are grafted into the affected area.
The surgeon harvests one or more plugs of cartilage and underlying bone from a less weight-bearing area of the patient’s knee and transfers them to a focal defect in the same knee. Orthopedic surgeons use this approach for selected cartilage and osteochondral injuries, including defects associated with osteochondritis dissecans. The service is performed through an open approach, commonly in a hospital or ambulatory surgery setting.
Report the code when the operative record supports open autologous osteochondral grafting, including the defect’s location and the harvest and recipient sites. Distinguish it from grafting with donor tissue or from cartilage-cell implantation. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For same-session procedures, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

27416 billing questions
How does this differ from 27415?
This code is for osteochondral tissue harvested from the same patient. Code 27415 is the open procedure using donor osteochondral tissue.
How does this differ from 27412?
This code transfers osteochondral plugs, including bone, from the patient’s own knee. Code 27412 describes knee treatment using an autologous chondrocyte implant rather than transferred osteochondral plugs.
When is 29866 more appropriate?
Code 29866 describes arthroscopic osteochondral autografting. Use 27416 for the open approach when the documented procedure meets its service description.
What operative details support reporting?
Document the focal defect and its knee location, the open grafting technique, and the autologous harvest and recipient sites. Include laterality.
How is bilateral treatment reported?
For bilateral procedures, modifier 50 is paid at 150% under the CMS facts provided. The 90-day global period applies to the surgery.
Can an assistant surgeon be reported?
Assistant-at-surgery payment is allowed only when medical necessity is documented. Co-surgeons and team surgery are not permitted.
