Replacement or repair of implantable component or components of total replacement heart system (artificial heart), excluding thoracic unit

The procedure described by CPT® Code 0053T involves the replacement or repair of implantable components within a total replacement heart system, commonly referred to as an artificial heart. This procedure is specifically focused on components other than the thoracic unit, which is the main body of the artificial heart system. An artificial heart is typically implanted in patients who are awaiting a donor heart, serving as a temporary solution to maintain circulation and support vital organ function. The process begins with a median sternotomy, a surgical incision made along the sternum to access the heart. During the procedure, cardiopulmonary bypass is established to take over the function of the heart and lungs, allowing the surgeon to operate on a still and bloodless field. The patient's diseased heart is then removed through a process known as cardiectomy. Following this, the artificial heart is carefully inserted into the chest cavity, and the coronary arteries are connected to the appropriate outlets of the artificial heart to ensure proper blood flow. After the insertion, the patient is gradually weaned off the cardiopulmonary bypass, chest tubes are placed to drain any excess fluid, and the chest incisions are meticulously closed. It is important to note that while CPT® Code 0052T pertains to the replacement of the pump of the artificial heart, CPT® Code 0053T specifically addresses the replacement of other components, such as an oxygenator, which are essential for the functioning of the total replacement heart system.
