CPT® Code 92997

The procedure described by CPT® Code 92997 refers to a percutaneous transluminal pulmonary artery balloon angioplasty performed on a single vessel. This minimally invasive technique is utilized to address pulmonary artery stenosis, a condition characterized by the narrowing of the pulmonary artery, which can impede blood flow from the heart to the lungs. During the procedure, the physician accesses the vascular system typically through the femoral artery, preparing the skin and puncturing the artery to insert a sheath. A guidewire is then navigated through the aorta and into the affected pulmonary artery, allowing for the advancement of a catheter. This catheter is equipped to inject contrast material, enabling the physician to visualize the narrowed area through imaging techniques. The procedure involves the inflation of a balloon at the site of stenosis, which dilates the narrowed segment of the pulmonary artery. The balloon may be inflated multiple times to achieve optimal dilation, and if necessary, a larger balloon-tipped catheter can be used for further treatment. Following the dilation, a completion angiography is performed to confirm the effectiveness of the procedure and ensure that the pulmonary artery has been adequately treated. This code is specifically designated for the treatment of a single pulmonary artery, while additional pulmonary arteries treated during the same session would be coded using CPT® Code 92998.
