CPT® Code 92920

The procedure described by CPT® Code 92920 refers to a percutaneous transluminal coronary angioplasty (PTCA) performed on a single major coronary artery or its branch. This minimally invasive technique is utilized to treat coronary artery disease, which is characterized by the narrowing or blockage of the coronary arteries due to the buildup of plaque. During the procedure, the physician accesses the coronary artery through the skin, typically using one of the femoral arteries. A needle punctures the artery, and a sheath is inserted to facilitate the introduction of a guidewire. This guidewire is carefully navigated through the aorta and into the affected coronary artery, allowing for the advancement of a catheter equipped with a balloon tip. Once positioned at the site of the blockage, the balloon is inflated, compressing the plaque against the arterial wall, which helps to restore blood flow. The inflation of the balloon may be repeated multiple times to achieve optimal results. Following the angioplasty, the catheter is withdrawn, and a contrast agent is injected to perform a completion angiography, ensuring that the treated artery remains open and patent. It is important to note that for procedures involving additional branches of a major coronary artery, CPT® Code 92921 should be reported in conjunction with 92920.
