CPT® Code 0234T

Transluminal peripheral atherectomy, open or percutaneous, including radiological supervision and interpretation; renal artery

The CPT® Code 0234T refers to a specific medical procedure known as transluminal peripheral atherectomy, which can be performed either through an open surgical approach or a percutaneous (minimally invasive) technique. This procedure is specifically focused on the renal artery, which supplies blood to the kidneys. During the atherectomy, the physician utilizes radiological supervision and interpretation to guide the procedure effectively. The term "atherectomy" refers to the surgical removal of atherosclerotic plaque from the arterial wall, which can help restore normal blood flow. In the case of an open approach, the physician prepares the skin over the access artery, makes an incision, and exposes the artery to facilitate the procedure. Conversely, in a percutaneous approach, a needle is used to puncture the skin and access the artery, typically through the femoral artery. The procedure involves the insertion of a guidewire and an atherectomy catheter, which is designed to shave away plaque using a specialized cutting piston. The plaque is collected within the device and removed upon completion of the procedure. Following the atherectomy, angiography is performed to confirm the patency of the renal artery or other treated arteries. The procedure concludes with appropriate closure techniques based on the approach used, ensuring patient safety and recovery.
