CPT® Code 29835

The procedure described by CPT® Code 29835 refers to a surgical arthroscopy of the elbow specifically for a partial synovectomy. This minimally invasive technique involves the removal of the synovial tissue from one compartment of the elbow joint. The procedure is typically indicated for patients experiencing symptoms related to synovial inflammation or other conditions affecting the elbow joint. During the surgery, the patient is positioned in a lateral decubitus position, which allows for optimal access to the elbow while ensuring the forearm can move freely. The surgeon makes incisions at midlateral and posterior portals to access the joint. The posterior compartment is examined first, and if necessary, the synovium surrounding the olecranon fossa is excised using an arthroscopic shaver. The medial gutter is then addressed, where small rongeurs are utilized to clear any obstructive tissue. Care is taken to protect the ulnar nerve during this process. Following the posterior compartment work, anterior portal incisions are created to explore the anterior compartment, where additional synovectomy is performed. The procedure concludes with the flushing of the compartments with saline solution and closure of the incisions. This code is specifically used for cases where only one compartment is treated, distinguishing it from CPT® Code 29836, which is used for complete synovectomy involving both compartments of the elbow.
