Cardiac surgery

About 33251: Open supraventricular focus ablation with bypass

Reports open surgical ablation of a supraventricular arrhythmogenic focus or pathway when the operation is performed with cardiopulmonary bypass.

This code covers an open operation to ablate a supraventricular arrhythmogenic focus or pathway, such as a pathway responsible for Wolff-Parkinson-White syndrome. A cardiac surgeon typically performs the procedure in the operating room with cardiopulmonary bypass. It is distinct from catheter-based electrophysiologic ablation and from broader atrial tissue ablation procedures used for atrial fibrillation.

Select the code when the operative report supports ablation of a supraventricular focus or pathway and documents use of cardiopulmonary bypass; the no-bypass counterpart is 33250. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard multiple procedure reduction. Modifier 50 is inappropriate. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

33251 billing questions

How does 33251 differ from 33250?

Both describe operative ablation of a supraventricular arrhythmogenic focus or pathway. Use 33251 when the operation uses cardiopulmonary bypass; 33250 is the no-bypass counterpart.

Is this the code for a catheter ablation?

No. This code describes open surgical ablation performed with cardiopulmonary bypass. Catheter-based electrophysiologic ablation is a different service.

Can modifier 50 be appended?

No. CMS identifies bilateral adjustment as inappropriate for this code because of its descriptor or anatomy.

What postoperative care is included?

The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.

Can an assistant or co-surgeon be reported?

Assistant-at-surgery services may be paid. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
