    CPT 00537: Anesthesia for Cardiac Electrophysiology Procedures

    Commercial payers pay $83 on average nationally for this procedure.

    CPT code 00537 describes anesthesia services for cardiac electrophysiologic procedures, covering management of anesthesia during mapping, pacing, recording, arrhythmia induction, lead testing, and radiofrequency ablation; service type: anesthesia for invasive cardiac electrophysiology procedures; typical site of service: hospital operating room or cardiac catheterization/electrophysiology lab.

    Clinical & Coding Specifications

    Clinical Context

    A 62-year-old male with symptomatic paroxysmal atrial fibrillation (I48.91) and intermittent supraventricular tachycardia (I47.1) is scheduled for an elective electrophysiology study with planned radiofrequency catheter ablation of an arrhythmogenic focus. The patient has hypertension and coronary artery disease, ASA class P3, and is brought to the cardiac catheterization/electrophysiology laboratory. Preoperative evaluation includes review of medications (anticoagulants management), airway assessment, and focused cardiac exam. An anesthesia team (Anesthesiology Physician, taxonomy 207L00000X) places standard monitors, obtains intravenous access, and induces monitored anesthesia care or general anesthesia depending on procedural complexity and patient factors. During mapping and pacing, the electrophysiologist (Cardiac Electrophysiology Physician, taxonomy 207RA0000X) performs intracardiac recordings and arrhythmia induction. The anesthesia provider manages hemodynamics, sedation level, and airway, treats arrhythmia-related hemodynamic instability, and documents intra-procedural anesthetic technique and medications. Post-procedure, the patient is transferred to post-anesthesia care for monitoring of rhythm, vascular access sites, and anticoagulation plan before discharge or admission for observation.
