CPT® Code 92937

Percutaneous transluminal revascularization of or through coronary artery bypass graft (internal mammary, free arterial, venous), any combination of intracoronary stent, atherectomy and angioplasty, including distal protection when performed; single vessel

The procedure described by CPT® Code 92937 involves the percutaneous transluminal revascularization of a coronary artery bypass graft that may be occluded or narrowed due to stenosis. This intervention is performed through the use of various techniques, including angioplasty, atherectomy, and the placement of intracoronary stents. The goal of this procedure is to restore blood flow through the bypass graft, which may have become compromised. The access point for this procedure is typically through the femoral artery, where the skin is prepped and punctured to insert a sheath. A guidewire is then navigated into the occluded graft, allowing for further evaluation and treatment. The use of radiological supervision is essential during this process to ensure accurate placement and monitoring of the devices used. The procedure may involve the inflation of a balloon to compress plaque against the arterial wall, the shaving of plaque through atherectomy, or the deployment of a stent to maintain the graft's patency. Following the intervention, a completion angiography is performed to confirm the success of the revascularization, ensuring that the artery is open and blood flow is restored. This procedure is specifically coded as 92937 when a single vessel is treated, with additional codes available for further branches involved in the bypass graft.
