CPT® Code 29880

Arthroscopy, knee, surgical; with meniscectomy (medial AND lateral, including any meniscal shaving) including debridement/shaving of articular cartilage (chondroplasty), same or separate compartment(s), when performed

The CPT® Code 29880 refers to a surgical procedure known as arthroscopy of the knee, specifically involving a meniscectomy that includes both the medial and lateral menisci. A meniscectomy is a surgical intervention performed to remove a torn meniscus, which is a C-shaped cartilage in the knee that acts as a cushion between the femur and tibia. This procedure is typically indicated when the tear is located in the non-vascular region of the meniscus, where it is unlikely to heal naturally, even with repair attempts. The procedure begins with the creation of small incisions, known as portal incisions, on both the medial and lateral sides of the knee joint. An arthroscope, a specialized instrument equipped with a camera, is inserted through one of these portals to visualize the internal structures of the knee. A cannula is then introduced through a second portal to facilitate the flushing of the joint with saline solution, which helps in cleaning the area and providing a clearer view of the knee's condition. The surgeon examines the knee for any signs of disease, injury, or infection, and locates the torn meniscus. The extent of the tear is assessed using a small hook, and the damaged portion of the meniscus is carefully resected and removed using various instruments such as basket forceps, motorized shavers, scissors, or knives. The procedure also includes debridement of the remaining meniscus to ensure smooth edges and may involve chondroplasty, which is the shaving or smoothing of the articular cartilage to enhance joint function. If tears are present in both the medial and lateral compartments, the surgeon addresses the second compartment in a similar manner. After the completion of the procedure, all instruments are removed, the incisions are closed, and a compressive dressing is applied to support the knee during recovery.
