Cardiac surgery
About 33975: Extracorporeal biventricular assist device placement
Reports surgical placement of an external ventricular assist system providing temporary support to both sides of the heart, commonly for severe cardiac failure.
This service covers surgical placement of an extracorporeal ventricular assist system configured to support both the right and left sides of the heart. A cardiac surgeon typically performs it in an operating room for severe cardiac failure, such as cardiogenic shock or postcardiotomy failure, when temporary mechanical circulatory support is needed. The system uses cannulae and an external pump to assist circulation; it is distinct from an implanted intracorporeal pump.
Select this code when the placed extracorporeal system provides biventricular support, rather than support of only one ventricle. The operative report should identify the device configuration, cannulation and pump placement, and the clinical need for support. When this and other procedures are performed in the same session, CMS applies the standard multiple procedure reduction: the highest-valued procedure is paid in full and the others at 50%.

33975 billing questions
How does this differ from 33976?
This code is for an extracorporeal system supporting both ventricles. Use 33976 when the extracorporeal device supports a single ventricle.
Does biventricular support mean reporting two units?
The defining distinction is the device configuration: support of both sides of the heart. Document that configuration rather than counting each ventricle as a separate service.
What documentation supports reporting this code?
The operative report should describe placement of the extracorporeal pump system, the cannulation and support configuration, and the need for biventricular assistance.
How does CMS reduce payment when other procedures are performed?
For procedures performed in the same session, CMS pays the highest-valued procedure in full and the others at 50% under the standard multiple procedure reduction.
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.
