About 33979: Implantable single-ventricle assist device insertion
Reports surgical placement of an implantable intracorporeal ventricular assist device configured to support one ventricle, commonly for advanced heart failure.
This code describes surgical implantation of an intracorporeal ventricular assist device to support one ventricle. Cardiothoracic surgeons typically perform the operation in a hospital operating room for patients with advanced heart failure who need mechanical circulatory support, such as as a bridge to transplant or longer-term therapy. The operative record should establish that the device is implantable and intracorporeal and identify the ventricle supported.
Select this code for the implanted, single-ventricle configuration; extracorporeal devices and percutaneous catheter-delivered support use different codes. Documentation should describe the device placement and whether support is for one ventricle or both. When multiple procedures subject to the CMS multiple procedure reduction are performed in the same session, the highest-valued procedure is paid in full and the others are paid at 50%.
