00537 Anesthesia cardiac ep procedures
Also known as: EP study anesthesia, cardiac ablation anesthesia, AFib ablation anesthesia
Anesthesia for cardiac electrophysiologic procedures including catheter ablation. Covers general anesthesia or deep sedation for diagnostic electrophysiology studies and ablation procedures for cardiac arrhythmias.
In Plain Language
anesthesia for heart rhythm mapping and treatment; being put to sleep for heart rhythm correction procedure
Clinical Context
Used when providing anesthesia for cardiac electrophysiology procedures including diagnostic EP studies, catheter ablation of SVT, atrial fibrillation ablation, and VT ablation. Increasingly performed under general anesthesia, especially for AF ablation with 3D mapping systems.
RVU Information
CPT 00537 does not have a physician work RVU assigned by CMS. Anesthesia codes use a base unit + time unit system rather than standard RVUs. Contact your payer for the anesthesia conversion factor.
Billing & Documentation
Anesthesia codes are billed using base units plus time units. One time unit typically equals 15 minutes of anesthesia time. Document start and stop times, patient status (P1-P6), and any qualifying circumstances. Modifiers AA, QK, QX, or QY indicate the provider arrangement.
