CPT® Code 33011

Deleted

The procedure described by CPT® Code 33011 refers to a subsequent pericardiocentesis, which is a medical intervention aimed at draining excess fluid from the pericardial space surrounding the heart. The pericardium is a double-walled sac that contains the heart and provides it with protection and lubrication. In cases where fluid accumulates in this space, it can lead to complications such as cardiac tamponade, which can impair the heart's ability to function effectively. During this procedure, the physician utilizes a long needle, typically inserted below the sternum, to access the pericardial cavity. Local anesthesia is administered to minimize discomfort for the patient. Once the needle is positioned correctly, fluid is aspirated or withdrawn from the pericardial space. After the necessary amount of fluid has been removed, the needle or catheter is carefully taken out, and a dressing is applied to the site of insertion. It is important to note that this code is specifically designated for subsequent procedures, following an initial pericardiocentesis, which is coded under CPT® Code 33010. This distinction is crucial for accurate medical coding and billing practices.
