About 27333: Open medial and lateral knee meniscectomy
Reports open removal of meniscal cartilage from both the medial and lateral compartments of one knee during the same operative session.
This code describes an open knee procedure in which the surgeon removes meniscal cartilage from both the medial and lateral compartments of the same knee through an arthrotomy. It is typically performed by an orthopedic surgeon in an operating room when both menisci require removal, such as for meniscal tears treated by an open approach. The code represents treatment of both compartments in one knee, not a single-meniscus procedure.
Report it when the operative note supports open removal from both menisci; documentation should identify the approach and the medial and lateral work performed. For same-session procedures, CMS applies the standard multiple-procedure reduction: the highest-valued procedure is paid in full and others at 50%. For treatment of both knees, modifier 50 is paid at 150%. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care. Assistant-at-surgery payment may be available; co-surgeons are paid only with supporting documentation, and team surgery is not permitted.
