CPT® Code 20611

Arthrocentesis, aspiration and/or injection, major joint or bursa (eg, shoulder, hip, knee, subacromial bursa); with ultrasound guidance, with permanent recording and reporting

Arthrocentesis, aspiration, and/or injection of a major joint or bursa is a medical procedure that involves the extraction of fluid from a joint or bursa, or the administration of medication into these areas. This procedure is typically performed to diagnose the underlying cause of joint effusion, which is the accumulation of excess fluid in the joint space, and to alleviate pain associated with this condition. The procedure may involve the use of ultrasound guidance to enhance the accuracy of needle placement, ensuring that the fluid is effectively aspirated or that the medication is precisely injected into the targeted area. The use of ultrasound not only aids in visualizing the joint or bursa but also allows for a permanent recording and reporting of the procedure, which is essential for documentation and follow-up care. The common practice during this procedure includes cleansing the skin over the joint, administering a local anesthetic if necessary, and then inserting a needle attached to a syringe into the affected area to remove fluid. This fluid is often sent for laboratory analysis to assist in diagnosing any underlying conditions. Following the aspiration, an injection of an anti-inflammatory medication, such as a steroid, may be performed to reduce inflammation and pain in the joint or bursa. It is important to note that this specific code, CPT® 20611, is designated for cases where ultrasound guidance is utilized, distinguishing it from similar procedures that do not employ this imaging technique.
