About 27415: Open knee osteochondral allograft transplant
Open knee osteochondral allograft transplantation restores a focal articular-surface defect using donor cartilage and its supporting bone.
This open knee procedure restores a focal articular-surface defect by implanting donor osteochondral tissue—cartilage with its supporting bone—into a prepared recipient site. Orthopedic surgeons use it for selected symptomatic defects of a knee joint surface, such as a femoral condyle, when donor tissue is needed to replace damaged cartilage and underlying bone. It is generally performed in an operating room, commonly in a hospital facility.
Report 27415 when the operative documentation supports an open allograft transplant, rather than tissue harvested from the patient or a cell-based implantation. Document the defect’s location, the recipient-site preparation, and use and implantation of donor tissue. The 90-day global period includes the day-before preoperative visit and related postoperative care through day 90. For multiple procedures in one session, the highest-valued procedure is paid in full and the others at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery services may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
