CPT® Code 33213

The procedure described by CPT® Code 33213 involves the insertion of a permanent cardiac pacemaker pulse generator when dual leads are already in place. A cardiac pacemaker is a medical device that delivers electrical impulses to the heart, ensuring it beats at a consistent and appropriate rate, thereby maintaining a normal cardiac rhythm. This is particularly important for patients whose hearts may not function effectively on their own due to various cardiac conditions. The pacemaker system can consist of one or more leads, which are the wires that connect the pulse generator to the heart. These leads can be positioned either on the surface of the heart (epicardial) or within the heart chambers (endocardial). During the procedure, a surgical incision is typically made in the left pectoral region, where a subcutaneous pocket is created to house the pulse generator. The existing leads are then connected to the new pulse generator, which is subsequently tested to ensure proper functionality. Once confirmed that the leads and generator are operating correctly, the pulse generator is securely placed into the pocket, sutured to the underlying tissue, and the incision site is closed. This procedure is specifically coded as 33213 when it is performed with existing dual leads, distinguishing it from other codes that may apply to different configurations of pacemaker systems or lead placements.
