The procedure described by CPT® Code 75680 involves angiography of the carotid arteries, which are major blood vessels located in the neck that supply blood to the brain, neck, and face. In this procedure, a physician performs a diagnostic imaging technique to visualize the internal structure of the carotid arteries. The process begins with the insertion of a catheter, a thin flexible tube, into both carotid arteries, which are situated on either side of the neck. Once the catheter is in place, a contrast dye is injected through it into the arteries. This dye enhances the visibility of the arteries on X-ray images. As the dye circulates through the blood vessels, the physician captures a series of X-ray images, allowing for detailed examination of the arteries' condition. This procedure is crucial for diagnosing various conditions affecting the carotid arteries, such as blockages, stenosis, or other vascular abnormalities, and is performed under radiological supervision to ensure accurate interpretation of the images obtained.
