What 33903 covers
An interventional cardiologist, often a specialist in congenital heart disease, performs catheter-based treatment to restore blood flow through abnormal native pulmonary arteries on both sides. Typical cases include branch pulmonary artery narrowing associated with congenital heart disease or remaining after prior repair. The procedure is performed in a cardiac catheterization lab and may use balloon treatment or stent-based treatment.
Select this code when the treated anatomy is abnormal and the intervention is bilateral; the related codes distinguish normal from abnormal anatomy and unilateral from bilateral treatment. The procedure report should identify the anatomy, treated sides, and intervention performed. The 0-day global period includes routine same-day preoperative and postoperative care. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures at 50%. Modifier 50 does not increase payment because the code is priced as bilateral. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.
