What 33920 covers
This operation treats pulmonary atresia with a ventricular septal defect, a congenital defect in which the normal route from the right ventricle to the pulmonary arteries is absent. A congenital cardiac surgeon reconstructs pulmonary blood flow and addresses the septal defect; repair may include an RV-to-pulmonary artery conduit. It is performed in an operating room, typically in a hospital, for patients requiring definitive correction of this complex heart defect.
Select the code when the operation repairs pulmonary atresia with the associated VSD, whether or not the pulmonary arteries are hypoplastic. The operative report should establish the congenital anatomy and describe the repair performed. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment may be available; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

How to choose
- 33925Pulmonary artery repair

- 33926Pulmonary artery repair
- This code describes pulmonary artery unifocalization with cardiopulmonary bypass. The bypass distinction separates it from 33925; 33920 represents repair of pulmonary atresia with VSD.
- 33917Pulmonary artery repair
- 33917 is for repair of a pulmonary artery. Use 33920 when the operation is repair of pulmonary atresia with the associated VSD, not an isolated pulmonary artery repair.
33920 billing questions
When is this code appropriate instead of 33925 or 33926?
Use 33920 for repair of pulmonary atresia with a VSD. Codes 33925 and 33926 describe pulmonary artery unifocalization without or with cardiopulmonary bypass, respectively.
Does pulmonary artery hypoplasia change code selection?
No. The repair represented by 33920 includes cases with or without pulmonary artery hypoplasia.
Should modifier 50 be appended?
No. CMS identifies bilateral adjustment as inappropriate for this code.
Can an assistant surgeon or co-surgeon be reported?
Assistant-at-surgery payment may be available. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
What documentation supports reporting 33920?
Document pulmonary atresia with the VSD and the operative work performed to repair the congenital anatomy. Include the relevant pulmonary artery anatomy, such as hypoplasia when present.
