CPT® Code 20606

Arthrocentesis, aspiration and/or injection, intermediate joint or bursa (eg, temporomandibular, acromioclavicular, wrist, elbow or ankle, olecranon bursa); with ultrasound guidance, with permanent recording and reporting

Arthrocentesis, commonly referred to as aspiration, is a medical procedure aimed at removing excess fluid from a joint or bursa. This procedure is essential for diagnosing the underlying causes of joint effusion, which is the accumulation of fluid in the joint space, and for alleviating pain associated with this condition. During arthrocentesis, a healthcare professional may also inject medication into the joint or bursa to reduce inflammation and provide relief from discomfort. Typically, this medication is an anti-inflammatory agent, such as a steroid, which helps to decrease swelling and improve joint function. The procedure begins with the cleansing of the skin over the affected area to minimize the risk of infection. If necessary, a local anesthetic is administered to ensure patient comfort during the procedure. A needle attached to a syringe is then carefully inserted into the joint or bursa to withdraw the fluid, which is subsequently sent for laboratory analysis to aid in diagnosis. In cases where ultrasound guidance is utilized, the procedure is reported under CPT® Code 20606, which includes the requirement for permanent recording and reporting of the procedure. This code is specifically designated for intermediate joints or bursae, such as the temporomandibular joint, acromioclavicular joint, wrist, elbow, ankle, or olecranon bursa, when ultrasound guidance is employed to enhance the accuracy of needle placement.
