How do CPT codes 33745 and 33746 differentiate between the initial and subsequent intracardiac stent placements for shunts? Are there specific coding guidelines for multiple stents in the same vs. different locations during a single procedure? ...

Article Overview
This article reviews CPT coding guidance for transcatheter intracardiac shunt creation by stent placement in congenital cardiac cases. It focuses on how the primary and add-on CPT codes are distinguished, what related imaging and catheterization services are included, and when separate reporting may or may not apply in the context of other cardiovascular and diagnostic catheterization codes. It is relevant to cardiac catheterization coders, cardiovascular providers, and billing staff working with congenital heart procedures and shunting services.
Why This Topic Matters
Accurate reporting of these procedures depends on understanding which services are bundled, which are add-on, and how multiple intracardiac locations are handled during the same session. The article helps reduce coding errors in complex congenital heart interventions and improves alignment with CPT guidance.
