About 33814: Aortopulmonary window repair with bypass
Reports open surgical closure of a congenital aortopulmonary window when the repair is performed with cardiopulmonary bypass.
This code applies to surgical correction of an aortopulmonary window, an abnormal opening between the aorta and pulmonary artery. A cardiothoracic or congenital heart surgeon closes the communication during an open cardiac operation using cardiopulmonary bypass. The operative record should identify the defect and describe the repair and use of bypass.
Choose this code when bypass is used; code 33813 represents repair without bypass. Do not report both versions for the same repair. 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 50% reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment may be available; co-surgeons require supporting documentation, and team surgery is not permitted.

33814 billing questions
How does this code differ from 33813?

Can both 33814 and 33813 be reported for one repair?

What documentation supports reporting 33814?
The operative report should establish an aortopulmonary window, describe its surgical closure, and document use of cardiopulmonary bypass.
How are assistant and co-surgeon claims handled?
Assistant-at-surgery payment may be available. Co-surgeons are paid only with supporting documentation; team surgery is not permitted.
What postoperative care is included?
