CPT® Code 29845

Surgical arthroscopy of the wrist is a minimally invasive procedure that involves the examination and treatment of the wrist joint through small incisions. The specific procedure described by CPT® Code 29845 refers to a complete synovectomy, which is the surgical removal of the synovial tissue that lines the joint. This procedure is typically indicated for patients suffering from conditions that cause inflammation of the synovial tissue, such as rheumatoid arthritis. During the procedure, the patient is positioned supine, and a pneumatic tourniquet is applied to the upper arm to minimize blood flow to the area, enhancing visibility and control during surgery. The use of a wrist traction device allows for distraction of the wrist joint, facilitating a clearer view of the internal structures. The arthroscope, a specialized camera, is inserted through a small incision, enabling the surgeon to visualize the joint and identify inflamed tissue. The complete removal of this tissue is essential for alleviating symptoms and improving joint function. This procedure is distinct from a partial synovectomy, which is performed when only a portion of the synovial tissue is removed, and is coded differently (CPT® Code 29844).
