About 33660: Partial atrioventricular septal defect repair
Reports surgical correction of a partial atrioventricular septal defect, typically involving a primum atrial opening and repair of the left atrioventricular valve.
This code describes open surgical repair of a partial atrioventricular septal defect, often called a partial AV canal defect. The operation commonly closes the primum atrial septal opening and addresses the cleft or regurgitation of the left atrioventricular valve. Congenital heart surgeons typically perform the repair in a hospital operating room, often with cardiopulmonary bypass. The operative report should establish the defect as partial and describe the septal and valve anatomy treated.
Report the code when the surgeon repairs the partial AV canal defect; patch use does not by itself change the code selection. Distinguish it from intermediate or complete AV canal repairs by the documented anatomy and the surgeon’s classification. The 90-day global period includes the day-before preoperative visit and related postoperative care during the following 90 days. For multiple procedures in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate for this intracardiac repair. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

33660 billing questions
How is this code distinguished from an intermediate AV canal repair?
Use the documented anatomy and the surgeon’s classification. An intermediate defect has a ventricular component, while this code is for a partial defect.
Does patch use change the code?
No. Patch use does not determine the code level; the documented type of AV canal defect does.
Can the atrial septal and valve work be reported separately?
When those steps are part of repairing the partial AV canal defect, report the repair code for the operation rather than treating its integral components as separate procedures.
Should modifier 50 be reported?
No. The repair involves intracardiac anatomy for which bilateral adjustment and modifier 50 are inappropriate.
What documentation supports this code?
The operative report should identify a partial AV canal defect and describe the septal opening, atrioventricular valve findings, and repair performed.
How does the global period affect postoperative billing?
The 90-day global period includes the day-before preoperative visit and related postoperative care during the 90 days after surgery.
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.
