Congenital cardiac surgery
About 33645: Anomalous pulmonary vein rerouting
Reports open surgical correction of partial or total anomalous pulmonary venous return by rerouting the abnormal drainage to restore pulmonary venous flow to the heart.
This open-heart operation corrects congenital pulmonary veins that drain abnormally rather than returning blood to the left atrium. A congenital cardiac surgeon reroutes the affected venous drainage, typically using cardiopulmonary bypass. The operation is performed in a hospital operating room for patients with partial or total anomalous pulmonary venous return; the operative report identifies the abnormal connection and the repair performed.
Select this code when the documented operation addresses the anomalous pulmonary venous return, rather than an isolated septal defect or a broader redo congenital repair. Documentation should describe the anomalous veins, their drainage site, and the rerouting performed. CMS assigns a 90-day global period, including the day-before preoperative visit and 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 50% reduction. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted. Modifier 50 is inappropriate for this procedure.
CMS billing rules for 33645

Office rates for Ohio, from the same CMS release.
Use this code for pulmonary venous rerouting. Code 33647 describes a septal defect repair, so it is not selected solely because a septal defect is present.
This code is specific to anomalous pulmonary venous return repair. Code 33622 is the redo-complex-anomaly option when the documented operation is reported as a broader redo repair.

33645 billing questions
When should this code be selected instead of an atrial septal defect repair code?
Use this code when the operation surgically redirects anomalous pulmonary venous drainage. An atrial septal defect code describes a septal repair when that is the operative target; review the full operative report when both abnormalities are addressed.
Does the 90-day global period include postoperative care?
Yes. The global period includes the day-before preoperative visit and 90 days of related postoperative care.
How are other procedures performed in the same session paid?
Under the standard multiple procedure reduction, the highest-valued procedure is paid in full and other procedures are paid at 50% when performed in the same session.
Can modifier 50 be used for right- and left-sided pulmonary veins?
No. Modifier 50 is inappropriate for this procedure; the repair is reported as a single cardiac operation, not as a bilateral service.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment may be made. Co-surgeon payment requires supporting documentation, and team surgery is not permitted.
What operative details support reporting this code?
Document the anomalous venous drainage, the veins and drainage site involved, and the surgical rerouting performed. The record should make clear that the operation corrected anomalous pulmonary venous return.
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.
