About 33647: Sinus venosus atrial septal defect repair
Reports open surgical repair of a sinus venosus atrial septal defect, including cases with an associated anomalous pulmonary venous connection.
This code describes open repair of a sinus venosus atrial septal defect, with or without an associated anomalous pulmonary venous connection. The operation typically closes the abnormal communication and, when needed, redirects pulmonary venous blood to the left atrium. A congenital cardiac surgeon performs the repair in a hospital operating room; the operative report should identify the defect and describe the repair and any anomalous venous connection addressed.
Select the code by the documented defect anatomy, not by whether the surgeon uses a patch. The code includes repair with or without a patch and covers the associated anomalous pulmonary venous connection when present; do not separately report 33645 for the same repair. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For other procedures 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 allowed; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

33647 billing questions
How does 33647 differ from 33641?
33647 is for a sinus venosus-type defect, with or without anomalous pulmonary venous connection. 33641 is for a secundum atrial septal defect.
Can 33645 be reported separately when anomalous pulmonary veins are redirected?
When the anomalous pulmonary venous connection is addressed as part of the sinus venosus defect repair, it is included in 33647. Do not separately report 33645 for that same repair.
Does use of a patch change code selection?
No. Code 33647 covers the sinus venosus defect repair with or without a patch; choose it based on the documented defect anatomy.
Can modifier 50 be used?
No. CMS identifies bilateral adjustment as inappropriate for this code, so modifier 50 is not appropriate.
What documentation supports reporting 33647?
The operative report should identify the sinus venosus-type defect and describe the closure or reconstruction performed, including any associated anomalous pulmonary venous connection addressed.
How are other procedures in the same operative session paid?
Under the standard multiple procedure reduction, the highest-valued procedure is paid in full and other procedures are paid at 50% when performed in the same session.
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.
