CPT® Code 0457T

Deleted

The procedure described by CPT® Code 0457T involves the removal of a permanently implantable aortic counterpulsation ventricular assist system, specifically focusing on the mechano-electrical skin interface component. This system is utilized primarily in the management of acute cardiogenic shock or end-stage chronic heart failure. The primary function of the device is to alleviate the workload of the left ventricle while enhancing cardiac output and blood flow, thereby providing critical support to patients with severe heart conditions. The aortic counterpulsation system comprises several key components, including a pneumatic pump, a console that operates the pump using pressurized air, and electrocardiogram electrodes that facilitate synchronization with the patient's heartbeat. The pneumatic pump is surgically implanted into a subcutaneous pocket located above the pectoralis muscle, with a pneumatic drive line exiting through the skin in the right upper abdomen to connect to the console. An interposition vascular graft is surgically anastomosed to the subclavian artery, allowing for the main graft to connect to the pump. Additionally, subcutaneous electrocardiogram electrodes are strategically placed on the chest wall and linked to the console, while mechano-electrical skin interface leads are positioned over the wrist, finger, or ankle to effectively capture the heartbeat and ensure proper synchronization of the pump's operation. During the removal procedure, an incision is made to access the pump, vascular graft, pneumatic drive tubing, and any subcutaneous electrodes present. The procedure requires careful disconnection of the device components, including clamping the vascular graft at the subclavian artery, excising the graft, and repairing the artery. The pneumatic drive tubing and electrodes are also disconnected before the complete removal of the device. This procedure is critical for patients who no longer require the support of the ventricular assist system or who may be transitioning to other forms of treatment.
