CPT® Code 70480

Computed tomography (CT), also known as computerized tomography, is a sophisticated imaging technique that utilizes specialized x-ray equipment and advanced computer technology to generate multiple cross-sectional images of specific body regions. The CPT® Code 70480 specifically refers to a CT scan performed on the orbit (eye socket), sella (the area housing the pituitary gland), posterior fossa (the region at the base of the skull), or any part of the ear (including outer, middle, or inner ear) without the use of contrast material. During the procedure, the patient is positioned on a CT examination table, and an initial scan is conducted to establish the starting position for the imaging process. As the table gradually moves through the scanner, x-ray beams and electronic detectors rotate around the targeted area, measuring the amount of radiation absorbed by the tissues. This data is then processed by a computer program, which creates two-dimensional cross-sectional images that are displayed on a monitor for the physician's review. The physician can assess these images in real-time and may request additional scans to focus on specific areas of interest. The findings from the CT scan are documented in a written interpretation by the physician, noting any abnormalities observed during the examination.
