Congenital cardiac surgery
About 33617: Single-ventricle repair with bypass
Open reconstruction for congenital single-ventricle anatomy, with or without shunt creation, reported when the repair uses cardiopulmonary bypass.
This code describes open surgical reconstruction for congenital heart disease in which the heart has a single functional ventricle, such as hypoplastic left heart syndrome. A congenital cardiac surgeon performs the repair using cardiopulmonary bypass; the service may include creation of a shunt. A Norwood-type operation is a characteristic example when the documented procedure matches this code. These operations are performed in a hospital operating room, commonly as part of staged treatment for complex congenital heart disease.
Select the code from the operative report’s description of the single-ventricle repair, use of bypass, and any shunt creation; the shunt is within the code’s scope. This major surgery has a 90-day global period, including the day-before preoperative visit and related postoperative care during that period. 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 not appropriate. Assistant-at-surgery payment may be available; co-surgeon payment requires supporting documentation, and team-surgery payment is not permitted.

33617 billing questions
What distinguishes this code from a Fontan repair code?
Use this code for the documented single-ventricle repair with cardiopulmonary bypass. A modified Fontan procedure has its own code entry; select based on the operation actually performed, not simply the patient’s single-ventricle diagnosis.
Is creation of a shunt included?
Yes. Shunt creation is within the described scope of this single-ventricle repair, whether or not a shunt is created.
What should the operative report document?
Document the congenital anatomy, the reconstruction performed, use of cardiopulmonary bypass, and whether a shunt was created. These details support selection of the single-ventricle repair code.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment may be available. Co-surgeon payment requires supporting documentation; team-surgery payment is not permitted for this code.
Does modifier 50 apply?
No. Modifier 50 is inappropriate for this repair because the descriptor and anatomy do not support bilateral adjustment.
How does the 90-day global period affect postoperative billing?
The global period includes the day-before preoperative visit and 90 days of related postoperative care. The code represents major surgery.
