Congenital cardiac surgery
About 33608: Congenital heart repair using conduit
Reports open repair of a congenital cardiac defect that uses a conduit, such as a pathway connecting a ventricle to the pulmonary artery.
This service involves open reconstruction of a congenital heart defect in which a conduit forms part of the repair, often routing blood from a ventricle to the pulmonary artery when the native outflow pathway is inadequate. A classic example is a Rastelli-type operation for transposition of the great arteries with a ventricular septal defect and pulmonary outflow obstruction. Congenital cardiac surgeons typically perform these operations in a hospital operating room, often with cardiopulmonary bypass.
Select the code from the operation performed and the conduit’s role in the reconstruction, not merely from the presence of conduit material. The operative report should identify the congenital anatomy, the repair, and how the conduit establishes or restores blood flow. CMS classifies this as major surgery with a 90-day global period, including the day-before preoperative visit and related postoperative care during that period. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and the others at 50%. Modifier 50 is inappropriate. Assistant-at-surgery payment may be available; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
CMS billing rules for 33608
- Global period
- Major surgery with a 90-day global period: the day-before preoperative visit and 90 days of related postoperative care are included.
- Multiple procedures
- Standard multiple procedure reduction: the highest-valued procedure is paid in full and others at 50% when performed in the same session.
- Bilateral procedures
- Bilateral adjustment does not apply; the descriptor or anatomy makes modifier 50 inappropriate.

33608 billing questions
When is this code chosen over a repair by enlargement?
Use this code when a conduit is part of the congenital defect repair. A repair that enlarges an existing opening without the conduit-based reconstruction is represented by a different code.
Does the presence of a conduit alone support this code?
No. The operative report should show that the conduit is part of the congenital cardiac reconstruction, such as creating a ventricular outflow pathway.
Can modifier 50 be reported?
No. CMS identifies bilateral adjustment as inappropriate for this code’s descriptor or anatomy.
How does the 90-day global period affect billing?
The day-before preoperative visit and related postoperative care for 90 days are included in the global period for this major surgery.
Can an assistant or co-surgeon be paid?
Assistant-at-surgery payment may be available. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
How are other procedures 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%.
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.
