CPT® Code 33214

Upgrade of implanted pacemaker system, conversion of single chamber system to dual chamber system (includes removal of previously placed pulse generator, testing of existing lead, insertion of new lead, insertion of new pulse generator)

The procedure described by CPT® Code 33214 involves the upgrade of an implanted pacemaker system, specifically converting a single chamber pacemaker to a dual chamber pacemaker. This upgrade is essential for patients who may be experiencing complications such as pacemaker syndrome, which can manifest as symptoms of heart failure due to retrograde P wave conduction. Additionally, this procedure may be indicated for patients with idiopathic hypertrophic subaortic stenosis who were initially treated with a ventricular pacemaker and require a transition to a dual chamber system for improved cardiac function. The process begins with the surgical removal of the existing single chamber pulse generator, followed by the testing of the existing lead to ensure its functionality. A new lead is then inserted, and a new pulse generator is placed to complete the upgrade. This procedure is performed through an incision in the upper chest, where access to the cephalic, subclavian, or jugular vein is achieved, allowing for the advancement of the pacemaker wire into the right atrium under radiological guidance. The successful completion of this procedure is critical for enhancing the patient's cardiac rhythm management and overall health outcomes.
