CPT code 24220 denotes arthrographic injection of contrast into the elbow joint to improve radiographic visualization of intra-articular structures and aid diagnosis of cartilage, ligament, or bony pathology. Nationally, this code supports diagnostic workflows that complement advanced imaging when assessing unexplained elbow pain, suspected intra-articular derangements, or preoperative evaluation. The procedure matters because accurate joint visualization can change downstream imaging, intervention, and surgical planning.
