What 33697 covers
This code represents definitive surgical correction of tetralogy of Fallot with pulmonary atresia. A congenital cardiac surgeon typically performs the open-heart operation in a hospital operating room. The repair addresses the intracardiac defect and establishes or reconstructs a pathway for blood to reach the pulmonary arteries; the exact reconstruction depends on the patient’s anatomy. It is distinct from a staged palliative operation that does not complete the repair.
Select the code from the documented diagnosis and operative report, especially whether pulmonary atresia is present and what definitive repair was performed. The comprehensive service includes maneuvers integral to that repair; do not separately report those steps as independent procedures. The 90-day global period includes 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 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.

33697 billing questions
How does this differ from codes 33692 and 33694?
This code is for tetralogy of Fallot with pulmonary atresia. Codes 33692 and 33694 describe repair when pulmonary atresia is absent, with 33694 distinguishing a repair that includes pulmonary artery reconstruction.
Can a staged palliative operation be reported with this code?
Use this code for definitive correction, not for a separate operation that only provides palliation. The operative report should support that the surgeon completed the repair.
Are the repair’s component maneuvers separately reportable?
Maneuvers integral to the comprehensive repair are included in the service. Review the operative report to distinguish integral steps from any separately performed, distinct procedure.
Can modifier 50 be used?
No. The CMS bilateral adjustment does not apply to this code, and modifier 50 is inappropriate.
How are assistant and co-surgeon claims handled?
Assistant-at-surgery payment may be made. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
