CPT® Code 70200

The CPT® Code 70200 refers to a complete radiologic examination of the orbits, which are the bony structures that house the eyes and associated ocular appendages. This examination involves a minimum of four views to ensure a comprehensive assessment of the orbital area. The procedure utilizes X-ray imaging, a technique that employs indirect ionizing radiation to create images of internal body structures. X-rays are particularly effective for visualizing non-uniform materials, such as human tissue, due to the varying densities and compositions of the tissues involved. As X-rays pass through the body, some are absorbed while others are transmitted, allowing for the capture of images on a detector positioned behind the area being examined. During the examination, X-rays are taken from multiple angles, including the parieto-orbital oblique view, lateral views, occipitomental projections, and an inclined PA or Caldwell view. These various positions are crucial as they enable clear visualization of the orbital structures without obstruction from the petrous ridges of the skull. The physician may instruct the patient to look in different directions, such as up and down, to enhance the clarity of the images obtained. The primary goal of this procedure is to allow the physician to review the resulting images for any signs of disease or abnormalities within the orbits, ensuring a thorough evaluation of the ocular region.
