Removal of a total replacement heart system (artificial heart) for heart transplantation (List separately in addition to code for primary procedure)

The procedure described by CPT® Code 33929 involves the removal of a total replacement heart system, commonly referred to as a total artificial heart (TAH), which is utilized in patients awaiting heart transplantation. A TAH is a sophisticated mechanical device designed to replace both ventricles of the heart, utilizing polyurethane structures and disc valves that are connected to an external pumping drive. This device serves as a temporary solution, or bridge, for patients with severe heart failure until a suitable donor heart becomes available for transplantation. The surgical process for removing the TAH requires a median sternotomy, which is an incision made through the breastbone to access the heart. During the removal procedure, the aorta and the superior and inferior vena cava are cannulated to establish heart-lung bypass, allowing the surgeon to safely disconnect the external drive lines from the pump device. The internal connectors are then carefully freed from the heart's leaflets, and the leaflets are inspected for any necessary repairs. This procedure is critical in the continuum of care for patients with end-stage heart disease, ensuring that they can transition to a donor heart when it becomes available.
