CPT® Code 70482

Computed tomography, orbit, sella, or posterior fossa or outer, middle, or inner ear; without contrast material, followed by contrast material(s) and further sections

Computed tomography (CT), commonly known as a CT scan, is a diagnostic imaging procedure that utilizes advanced x-ray technology and computer processing to create detailed cross-sectional images of specific areas within the body. The CPT® Code 70482 specifically refers to a CT scan performed on the orbit (eye socket), sella (the region housing the pituitary gland), posterior fossa (located at the base of the skull), or any part of the ear (including outer, middle, or inner ear). This procedure begins with the patient being positioned on a CT examination table, where an initial scan is conducted to establish the starting point for the imaging process. During the scan, the CT scanner emits x-ray beams that rotate around the targeted body region while electronic detectors measure the amount of radiation absorbed. This data is then processed by a computer to generate two-dimensional images that provide a comprehensive view of the area being examined. The physician monitors the imaging process in real-time and may request additional sections to enhance the detail of specific areas of interest. The procedure is characterized by its initial phase without the use of contrast material, followed by the administration of contrast material to obtain further detailed images. The physician subsequently reviews the CT images, identifies any abnormalities, and documents a written interpretation of the findings for clinical use.
