Percutaneous transluminal coronary atherectomy, with coronary angioplasty when performed; single major coronary artery or branch

The procedure described by CPT® Code 92924 involves a percutaneous transluminal coronary atherectomy, which is a minimally invasive technique used to remove plaque buildup from the coronary arteries. This procedure is typically performed when there is significant blockage in a major coronary artery or its branches, which can lead to reduced blood flow to the heart muscle and potentially result in angina or myocardial infarction. The atherectomy is often combined with coronary angioplasty, where a balloon is used to further open the artery after plaque removal. The access point for this procedure is usually through the femoral artery, where the skin is prepped, and a needle is used to puncture the artery, allowing for the insertion of a sheath. A guidewire is then navigated through the vascular system to the site of the blockage. The atherectomy device, equipped with a cutting piston, is utilized to shave away the plaque from the arterial wall, effectively clearing the blockage. Following the atherectomy, a balloon catheter may be employed to compress any residual plaque, ensuring that the artery remains open. Finally, a completion angiography is performed to confirm the success of the procedure and the patency of the treated artery.
