CPT® Code 33971

The procedure described by CPT® Code 33971 involves the removal of an intra-aortic balloon pump (IABP) assist device, which is a critical intervention used in patients with severe cardiac conditions. The IABP is designed to support the heart's function by inflating and deflating a balloon within the aorta, thereby enhancing coronary blood flow during diastole and reducing the workload of the heart during systole. This procedure is particularly relevant for patients who have undergone temporary mechanical support for heart failure or during high-risk cardiac surgeries. The removal of the IABP is performed through a surgical approach that includes a longitudinal incision in the groin to access the femoral artery. The femoral artery is then carefully exposed and controlled to facilitate the removal of the device and any necessary repairs to the artery itself. This may involve suturing the artery directly or utilizing a graft if the arterial integrity has been compromised. The procedure is essential for ensuring the patient's recovery and restoring normal arterial function following the use of the IABP.
