CPT code 29821 is a surgical procedure for complex synovectomy of the shoulder joint, often used to treat joint inflammation.
CPT code 29821 is used to describe a surgical procedure involving the shoulder joint, specifically a complex synovectomy. This procedure typically involves the removal of the synovial membrane, which is the lining of the joint that can become inflamed or thickened due to conditions such as arthritis. The code indicates that the surgery is performed arthroscopically, meaning it is done using small incisions and a camera, allowing for less invasive access to the joint.
