CPT code 93653: SVT ablation, comprehensive EP evaluation2026 Medicare rate & RVUs

Medicare pays $711.44 for 93653 nationally in a facility.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 93653 covers

An electrophysiologist performs this service in an electrophysiology lab, typically in a hospital or outpatient facility. Catheters are placed in the heart to record electrical activity and provoke or assess the tachycardia; the physician then maps and ablates the responsible tissue. Common targets include the circuit causing AV nodal reentrant tachycardia, an accessory pathway causing AV reentrant tachycardia, or a focus causing atrial tachycardia. Atrial fibrillation ablation and ventricular tachycardia ablation are reported with different codes.

Report 93653 when the comprehensive EP evaluation and ablation address a supraventricular tachycardia. The operative report should identify the clinical arrhythmia, study and mapping findings, ablation target, and treatment performed. The diagnostic EP work is part of this service; 3D mapping or ablation of a separate arrhythmia mechanism may be reported with the applicable additional code when performed and documented. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. For multiple procedures in one session, the highest-valued procedure is paid in full and other procedures at 50%. Modifier 50 is inappropriate. Assistant-at-surgery payment requires medical-necessity documentation; co-surgeons and team surgery are not permitted.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
