CPT® Code 27332

The procedure described by CPT® Code 27332 involves an arthrotomy, which is a surgical incision into the knee joint, accompanied by the excision of semilunar cartilage, commonly known as a meniscectomy. This procedure is indicated for patients with a torn meniscus that is deemed irreparable, particularly when the tear extends into the non-vascular region of the meniscus where healing is unlikely to occur even with repair attempts. The meniscus is a crucial structure in the knee, providing cushioning and stability, and tears can lead to significant pain and functional impairment. During the procedure, a skin incision is made over the knee joint, allowing access to the joint capsule. The surgeon carefully dissects the surrounding tissues to expose the joint capsule, which is then opened to facilitate a thorough examination of the knee joint. The joint is flushed with saline solution to clear any debris, and the extent of the meniscal tear is assessed. The damaged portion of the meniscus is meticulously resected using various surgical instruments, ensuring that only the affected tissue is removed while preserving as much healthy meniscal tissue as possible. The remaining meniscus is smoothed to promote optimal healing and function. If necessary, tears in both the medial and lateral compartments of the knee can be addressed during the same surgical session. After the procedure, the joint capsule and surrounding tissues are closed in layers, and a compressive dressing is applied to support the healing process. This code is specifically used when only one meniscus, either medial or lateral, is resected, while a different code (CPT® 27333) is used when both menisci are involved.
