Cardiac electrophysiology
About 93656: Atrial fibrillation catheter ablation
Reports catheter-based electrophysiologic evaluation and ablation for atrial fibrillation, typically isolating pulmonary veins during an electrophysiology lab procedure.
An electrophysiologist uses intracardiac catheters to evaluate the heart’s electrical activity and ablate tissue to treat atrial fibrillation, commonly by electrically isolating the pulmonary veins in the left atrium. The procedure is generally performed in a hospital electrophysiology laboratory, with catheter access and transseptal access used as clinically needed to reach the left atrium. The comprehensive electrophysiologic evaluation is part of the service.
Report 93656 for the atrial fibrillation ablation session, supported by documentation of the arrhythmia, the evaluation and ablation performed, and the treatment target. Code 93657 may be reported as an add-on when additional atrial ablation is performed for atrial fibrillation after pulmonary vein isolation. The code has a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures in the same session are subject to the standard reduction, the highest-valued is paid in full and others at 50%. Modifier 50 is inappropriate. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

93656 billing questions
When is 93656 selected instead of 93653 or 93654?
Use 93656 for catheter ablation treating atrial fibrillation, typically with pulmonary vein isolation. Codes 93653 and 93654 address ablation for supraventricular tachycardia and ventricular tachycardia, respectively.
Can 93657 be reported with 93656?
Yes. 93657 is an add-on for additional atrial ablation performed for atrial fibrillation after pulmonary vein isolation; document the additional treatment.
Is the diagnostic electrophysiologic evaluation separately reported?
The comprehensive electrophysiologic evaluation is included in 93656. A separate diagnostic study code should not be used to report that same evaluation.
Should modifier 50 be appended for pulmonary vein treatment on both sides?
No. CMS identifies bilateral adjustment as inappropriate for 93656, so do not use modifier 50 to represent treatment of pulmonary veins on both sides.
What does the 0-day global period mean for same-day care?
Same-day preoperative and postoperative care is included in the procedure. The CMS global period is 0 days.
What documentation supports reporting 93656?
Document atrial fibrillation as the treatment indication and describe the electrophysiologic evaluation and catheter ablation performed, including the targeted treatment and pulmonary vein isolation when performed.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
