CPT® Code 75660

Deleted

The procedure described by CPT® Code 75660 involves angiography of the external carotid artery, which is a critical vessel supplying blood to the head and neck. In this procedure, a physician performs a selective angiography, meaning that they specifically target one side of the external carotid artery, either the left or the right, rather than examining both sides simultaneously. The process begins with the insertion of a catheter, a thin, flexible tube, into the artery. This catheter is carefully navigated through the vascular system to reach the external carotid artery. Once in place, a contrast dye is injected through the catheter. This dye is essential as it enhances the visibility of the blood vessels during imaging. As the dye circulates through the artery, the physician captures a series of X-ray images. These images allow for detailed examination of the artery's structure and any potential abnormalities, such as blockages or malformations. The radiological supervision and interpretation of these images are crucial for diagnosing conditions affecting the external carotid artery and planning any necessary interventions.
