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.

How to choose
- 93619EP evaluationWithout arrhythmia induction
- Choose 93653 when the encounter includes ablation of an SVT mechanism. Choose 93619 for the comprehensive EP evaluation without ablation.
- 93654VT ablationComprehensive EP evaluation
- 93654 is for catheter ablation treating ventricular tachycardia; 93653 is for supraventricular tachycardia.
- 93656AF ablationPulmonary vein isolation
- 93656 is the comprehensive ablation service for atrial fibrillation. Use 93653 for other treated SVT mechanisms, such as AVNRT or an accessory pathway.
93653 billing questions
How is 93653 different from 93619?
93653 includes catheter ablation to treat the supraventricular arrhythmia. Use 93619 for a comprehensive EP evaluation without that ablation.
Can the diagnostic EP study be billed separately?
The diagnostic evaluation performed as part of the ablation service is included in 93653. Do not separately report a study-only code for that same work.
Can 3D mapping or ablation of another arrhythmia be reported separately?
When performed and supported by the record, 93613 may report 3D mapping, and 93655 may report ablation of a distinct additional arrhythmia mechanism. Document the separate service or target.
Should modifier 50 be appended for ablation on both sides?
No. CMS identifies bilateral adjustment as inappropriate for 93653, so modifier 50 is not used.
How does CMS reduce payment when other procedures are performed in the same session?
The highest-valued procedure is paid in full, and the other procedures are paid at 50%. Same-day preoperative and postoperative care is included in 93653's 0-day global period.
When is assistant-at-surgery payment allowed?
CMS pays an assistant only when medical necessity is documented. Co-surgeons and team surgery are not permitted for this code.
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.
