CPT® Code 92933

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

The procedure described by CPT® Code 92933 involves a percutaneous transluminal coronary atherectomy, which is a minimally invasive technique used to remove plaque buildup from the coronary arteries. This procedure is performed with the aid of an intracoronary stent and may include coronary angioplasty, which is the use of a balloon catheter to widen the artery. The access point for this procedure is typically through the femoral artery, where the skin is prepared, and a needle is used to puncture the artery, allowing for the insertion of a sheath. A guidewire is then navigated through the aorta and into the affected coronary artery that is blocked by plaque. The atherectomy process utilizes a specialized catheter equipped with a cutting piston that effectively shaves away the plaque from the arterial wall. As the plaque is removed, it is collected within the device for extraction at the end of the procedure. The physician may perform multiple passes with the atherectomy device to ensure thorough plaque removal. Following this, a balloon-tipped angioplasty catheter may be used to further compress any residual plaque, enhancing the artery's patency. Once the atherectomy and angioplasty are completed, a stent, which is initially collapsed, is advanced to the blockage site and expanded using the balloon catheter. This stent acts as a scaffold, maintaining the artery's openness and preventing future blockages. Finally, contrast dye is injected, and a completion angiography is conducted to confirm that the treated artery remains patent. This procedure is specifically indicated for a single major coronary artery or branch, with additional codes available for treatment of further branches.
