In simple words: The doctor fixes two wires (electrodes) inside the heart that are part of a pacemaker or defibrillator. These wires are disconnected, checked for problems, repaired if needed, and then reconnected.

This CPT code reports the repair of two transvenous electrodes from a permanent pacemaker or implantable cardioverter-defibrillator (ICD) pulse generator.The procedure involves disconnecting the electrodes, testing their functionality, repairing any defects, retesting, and reattaching them to the generator.The pulse generator is typically removed to access the electrodes. This is distinct from replacing the pulse generator itself.

Example 1: A patient with a dual-chamber pacemaker experiences malfunction due to damage to two transvenous leads.The physician performs the repair using 33220., A patient with an ICD experiences intermittent failure of two leads. After thorough evaluation, the physician repairs the two leads using 33220., Following a trauma, a patient's dual-chamber pacemaker has two leads damaged. The physician repairs these leads under fluoroscopic guidance using 33220.

Pre-operative assessment, operative report detailing the repair process, including lead testing results, intraoperative images (if applicable), and post-operative assessment of device function.

** This procedure is typically performed in a specialized electrophysiology lab or operating room under fluoroscopic guidance.Documentation should clearly indicate the specific malfunction and the nature of the repair.
