What 33927 covers

This operation implants a total replacement heart system, an artificial heart that takes over the pumping work of both ventricles. The procedure includes cardiectomy, or removal of the recipient’s heart. Cardiothoracic surgeons perform it in an operating room, generally for patients with end-stage biventricular failure who need complete ventricular support, often while awaiting transplantation. It is distinct from implanting a ventricular assist device that supports only one ventricle.

Report 33927 for the initial implantation with recipient cardiectomy, not for later removal and replacement of an existing system. The operative report should identify the indication, removal of the recipient’s heart, and implantation of the total replacement heart system. When multiple procedures are performed in the same session, Medicare pays the highest-valued procedure in full and reduces the others to 50% under the standard multiple-procedure rule.
