CPT® Code 33212

The procedure described by CPT® Code 33212 involves the insertion of a permanent cardiac pacemaker pulse generator that is connected to an existing single lead. A cardiac pacemaker is a medical device designed to deliver electrical impulses to the heart, ensuring it maintains a regular rhythm. This is particularly important for patients whose hearts may not beat adequately on their own due to various cardiac conditions. The pacemaker system can consist of a single lead, dual leads, or multiple leads, which 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 lead is then connected to the pulse generator, which is subsequently tested to confirm proper functionality. Once confirmed, the pulse generator is securely placed in the pocket, sutured to the underlying tissue, and the incision is closed. This code specifically applies to cases where the pulse generator is inserted with an existing single lead, distinguishing it from CPT® Code 33213, which pertains to the insertion of a pulse generator with existing dual leads.
