Congenital cardiac surgery
About 33766: Unilateral superior vena cava to pulmonary artery shunt
Reports a congenital heart operation connecting the superior vena cava to the pulmonary artery serving one lung, commonly for staged single-ventricle palliation.
A congenital cardiac surgeon creates a cavopulmonary connection by joining the superior vena cava to the pulmonary artery supplying one lung. This unilateral Glenn-type shunt redirects upper-body venous blood toward that lung and is used in selected congenital heart defects, often as part of staged palliation for single-ventricle physiology. The operative report should establish the vessels joined and that the connection serves one lung.
Select this code when the documented connection is to one lung; the bilateral-lung version is 33767. Record the anatomy, operative work, and clinical indication so the unilateral procedure can be distinguished from other systemic-to-pulmonary shunts. CMS assigns a 90-day global period, including 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 50% multiple-procedure reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment may be available; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

33766 billing questions
How does 33766 differ from 33767?
33766 describes a superior vena cava-to-pulmonary artery connection serving one lung. Use 33767 when the connection serves both lungs.
Should modifier 50 be appended for a bilateral operation?
No. CMS identifies bilateral adjustment as inappropriate for this code; the both-lungs procedure is represented by 33767.
What documentation supports reporting 33766?
The operative report should identify the superior vena cava and pulmonary artery joined, establish that the connection serves one lung, and describe the congenital indication.
How does the 90-day global period affect postoperative billing?
The day-before preoperative visit and 90 days of related postoperative care are included in the global period.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment may be made. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
What happens if other 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.
