CPT® Code 70140

The CPT® Code 70140 refers to a radiologic examination specifically focused on the facial bones, which is performed when fewer than three views are captured. This procedure involves the use of X-ray technology to create images of the facial structures, including key components such as the maxilla (upper jaw), mandible (lower jaw), frontal bone (forehead area), nasal bones (nose structure), and zygoma (cheekbone). X-ray imaging operates on the principle of ionizing radiation, which is directed towards the body. As the X-rays pass through the non-uniform material of human tissue, they are absorbed to varying degrees based on the density and composition of the tissues. This differential absorption allows for the creation of a two-dimensional image that reveals the internal structures of the face. The physician conducts this examination to identify any abnormalities, such as traumatic injuries, bony projections or growths, infections, and other signs of disease. It is important to report CPT® Code 70140 when the examination involves less than three distinct views of the facial bones, as this distinguishes it from more comprehensive examinations that require additional imaging perspectives.
