Congenital cardiac surgery
About 33764: Central systemic-to-pulmonary shunt with graft
Reports creation of a central systemic-to-pulmonary artery shunt using a prosthetic graft, typically to increase pulmonary blood flow in congenital heart disease.
A congenital cardiac surgeon creates a central connection from the systemic arterial circulation to the pulmonary artery using a prosthetic graft. The shunt provides additional pulmonary blood flow, often as palliation for a cyanotic congenital heart defect with inadequate flow to the lungs. The procedure is performed in an operating room; the operative report should identify the shunt’s origin and insertion and confirm use of a prosthetic graft.
Select this code for the central graft configuration, rather than choosing by the general goal of increasing pulmonary blood flow alone. Document the anatomy and construction so the central route can be distinguished from named subclavian or aortic shunt routes. This major surgery has a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in one session, the highest-valued is paid in full and others at 50%. Modifier 50 is inappropriate. Assistant-at-surgery payment may be available; co-surgeons require supporting documentation, and team surgery is not permitted.

33764 billing questions
How is this distinguished from a subclavian-to-pulmonary artery shunt?
This code is for the central shunt configuration using a prosthetic graft. A shunt originating from the subclavian artery is reported with 33750.
What operative details support code selection?
The report should establish the central route, identify the systemic arterial origin and pulmonary artery insertion, and document the prosthetic graft.
Can modifier 50 be used for a bilateral shunt?
No. CMS identifies bilateral adjustment as inappropriate for this code.
How does the 90-day global period affect postoperative reporting?
The day-before preoperative visit and 90 days of related postoperative care are included in the global period.
How are other procedures in the same session paid?
The highest-valued procedure is paid in full, and other procedures are paid at 50% under the standard multiple procedure reduction.
May an assistant or co-surgeon be reported?
Assistant-at-surgery payment may be available. Co-surgeons are paid only with supporting documentation; team surgery is not permitted.
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.
