CPT® Code 29883

A surgical arthroscopy of the knee, specifically coded as CPT® 29883, involves a minimally invasive procedure where the knee joint is examined and treated through small incisions. This procedure is performed when there are tears in the meniscus, which is the cartilage that cushions the knee joint. The meniscus has two main regions: the outer vascular region, which has a good blood supply and can heal effectively, and the inner avascular region, which has limited blood supply and may not heal as well. During the arthroscopy, portal incisions are made on both the medial (inner) and lateral (outer) sides of the knee to allow access to the joint. An arthroscope, a small camera, is inserted through one of these portals to visualize the interior of the knee. A cannula is then introduced through a second portal to facilitate the flushing of the joint with saline solution, which helps to clear debris and provides a clearer view of the joint structures. The surgeon examines the knee for any signs of disease, injury, or infection, and locates the meniscus tear. The extent of the tear is assessed using a small hook. The edges of the tear are prepared to promote healing, and various techniques may be employed to enhance blood supply to the area. The meniscus is then repaired using sutures or other fixation devices. If both the medial and lateral menisci are torn, both are addressed during the same procedure, ensuring comprehensive treatment of the knee joint. After the repairs are completed, the instruments are removed, and the incisions are closed with a compressive dressing applied to support recovery.
