About 33976: Extracorporeal biventricular assist device implantation
Reports surgical placement of an extracorporeal ventricular assist system supporting both ventricles, typically for temporary mechanical circulatory support in severe biventricular failure.
A cardiac surgeon places an extracorporeal ventricular assist system with cannulas connected to support both the right and left ventricles. The pump remains outside the body while providing temporary circulatory support, such as for a patient with severe biventricular failure who needs support while awaiting recovery or further treatment. The service is performed in a hospital operating room as part of surgical mechanical circulatory support.
Choose this code when the implanted system provides extracorporeal support to both ventricles; a single-ventricle extracorporeal system is a different code. The operative report should identify the device configuration and document support of both ventricles. CMS applies the standard multiple-procedure reduction when other qualifying procedures occur in the same session: the highest-valued procedure is paid in full and the others at 50%. The code is already priced as bilateral, so modifier 50 does not increase payment.

33976 billing questions
How does 33976 differ from 33975?
33976 represents an extracorporeal system supporting both ventricles. Use 33975 for an extracorporeal system supporting a single ventricle.
How does 33976 differ from 33979?
33976 is for an extracorporeal biventricular system. Code 33979 describes an implantable intracorporeal ventricular assist device, a different device configuration.
Should modifier 50 be appended?
CMS identifies 33976 as already priced bilaterally. Modifier 50 does not increase payment.
What happens when another procedure is performed in the same session?
Under the standard multiple-procedure reduction, the highest-valued procedure is paid in full and other qualifying procedures are paid at 50%.
What documentation supports reporting 33976?
The operative report should identify the extracorporeal device and establish that it provides ventricular support to both sides of the heart.
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.
