About 33901: Bilateral non-native pulmonary artery revascularization
Reports catheter-based revascularization of one non-native pulmonary artery vessel on both sides to restore blood flow through narrowed or obstructed arteries.
This code describes a catheter-based intervention to restore flow through one non-native pulmonary artery vessel on each side. It is used when bilateral pulmonary artery disease requires revascularization, such as in patients with congenital heart disease and prior pulmonary artery reconstruction. The intervention may involve dilation or placement of a stent as part of the revascularization. Cardiologists and congenital heart disease specialists typically perform the procedure in a catheterization laboratory or hospital setting.
Select this code when the treated vessels are non-native and the service is bilateral; the record should identify the anatomy treated and the intervention performed. The bilateral service is already reflected in the code, so modifier 50 does not increase payment. The 0-day global period includes same-day preoperative and 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. Assistant-at-surgery payment requires documentation of medical necessity; co-surgeons and team surgery are not permitted.

33901 billing questions
When should I choose 33901 instead of 33900?
Use 33901 for the bilateral service involving one non-native pulmonary artery vessel on each side. Code 33900 describes the unilateral counterpart.
Should modifier 50 be added?
No. Bilateral treatment is built into 33901, and modifier 50 does not increase payment.
What documentation supports reporting 33901?
Document the non-native pulmonary artery anatomy, the vessels treated on both sides, and the revascularization performed.
How does the 0-day global period affect same-day care?
Same-day preoperative and postoperative care is included in the procedure's global period.
Can an assistant surgeon be reported?
Assistant-at-surgery payment is available only when the record documents medical necessity. Co-surgeons and team surgery are not permitted.
How is 33904 used with this code?
Code 33904 represents each additional pulmonary artery vessel treated beyond the initial vessel service.
