What 33983 covers

This service covers exchanging the pump of an implanted intracorporeal ventricular assist device, with cardiopulmonary bypass used during the operation. A cardiothoracic surgeon typically performs the procedure in a hospital operating room. The patient already has an implanted VAD; this is pump replacement, not placement of a new VAD or replacement of an external pump. The bypass detail distinguishes this service from the corresponding intracorporeal pump replacement performed without bypass.

Select the code based on the device being replaced and whether cardiopulmonary bypass was used. The operative report should identify the implanted intracorporeal pump exchange and document bypass use. The replacement service describes the exchange; do not separately report removal of the pump being replaced as though it were an independent removal procedure. When multiple procedures are performed in the same session, CMS pays the highest-valued procedure in full and reduces the others to 50%.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.
