CPT® Code 92938

Add-On Code

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; each additional branch subtended by the bypass graft (List separately in addition to code for primary procedure)

The procedure described by CPT® Code 92938 involves the percutaneous transluminal revascularization of a coronary artery bypass graft that may be constructed from internal mammary arteries, free arterial grafts, or venous grafts. This complex intervention is performed to restore blood flow in cases where the bypass graft has become occluded or narrowed due to stenosis. The revascularization process can include a combination of techniques such as angioplasty, atherectomy, and the placement of intracoronary stents. The procedure is typically initiated by accessing the femoral artery, where the skin is prepped and punctured to insert a sheath. A guidewire is then navigated through the vascular system to reach the affected bypass graft. The physician evaluates the graft using a catheter and may employ a distal embolic protection device to prevent debris from traveling downstream during the intervention. Angioplasty involves inflating a balloon at the site of the blockage to compress plaque against the arterial wall, while atherectomy utilizes a specialized device to shave away plaque. If necessary, a stent may be deployed to maintain the artery's patency. Following the intervention, completion angiography is performed to confirm the success of the procedure, and appropriate post-procedure care is administered to the vascular access site.
