Congenital cardiac surgery
About 33783: Nikaidoh repair with coronary implantation
Reports a Nikaidoh aortic root translocation for complex transposition, including coronary ostia implantation, during congenital heart surgery.
This code describes a Nikaidoh repair in which the aortic root is translocated and the coronary ostia are implanted as part of the reconstruction. Congenital cardiac surgeons perform this complex operation in a hospital operating room, typically for transposition of the great arteries with a ventricular septal defect and significant subpulmonary or pulmonary outflow obstruction. The operative report should identify the anatomy treated and document the root translocation and coronary ostia implantation.
Report the code for the Nikaidoh operation with coronary ostia implantation, rather than for isolated coronary implantation. It has a 90-day global period: the day-before preoperative visit and related postoperative care during that period are included. When multiple procedures occur 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. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

How does this differ from 33782?
Both describe a Nikaidoh repair. Select the code that matches the operative service, including whether coronary ostia implantation is part of the procedure.
Should coronary ostia implantation be reported separately?
This code identifies the Nikaidoh procedure with coronary ostia implantation. The operative report should support that the implantation was performed as part of the repair.
Can modifier 50 be used?
No. The CMS bilateral adjustment does not apply to this procedure, and modifier 50 is inappropriate.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and related postoperative care during the 90 days after surgery.
Can an assistant or co-surgeon be paid?
Assistant-at-surgery payment may be made. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
