About 33745: Transcatheter congenital intracardiac shunt creation
Report this code for transcatheter creation of the first intracardiac shunt to manage a congenital cardiac anomaly, with imaging guidance included when performed.
A congenital interventional cardiologist creates an intentional blood-flow pathway within the heart using a transcatheter approach to address a congenital cardiac anomaly. The service is generally performed in a hospital catheterization laboratory, with imaging guidance included when performed. This code identifies the first shunt created; it is distinct from a transcatheter atrial septostomy and from an extracardiac surgical shunt between a systemic artery and the pulmonary artery.
Report the first shunt under 33745 and use 33746 for each additional shunt when supported by the procedure performed. The operative or catheterization report should establish the congenital anomaly, the shunt created, and whether additional shunts were created. The code has a 0-day global period, so same-day preoperative and postoperative care is included. 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. Assistant-at-surgery payment may be made; co-surgeons and team surgery are not permitted.

33745 billing questions
When should 33745 be reported instead of 33741?
Use 33745 for creation of an intracardiac shunt. Code 33741 describes transcatheter atrial septostomy for a congenital cardiac anomaly; select based on the procedure actually performed.
How is a second shunt reported?
Report 33745 for the first shunt and 33746 for each additional shunt created, when the procedure documentation supports the additional service.
Is imaging guidance separately reported?
Imaging guidance is included when performed as part of the service described by 33745; do not separately report it as though it were outside this procedure.
Can modifier 50 be used for bilateral work?
No. Modifier 50 is inappropriate for this code because the descriptor or anatomy does not support a bilateral adjustment.
How does the 0-day global period affect same-day care?
Same-day preoperative and postoperative care is included in the procedure. The code has a 0-day global period.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment may be made. Co-surgeons and team surgery are not permitted for this code.
