CPT® Code 70100

The CPT® Code 70100 refers to a radiologic examination of the mandible, specifically a partial examination that includes less than four views. This procedure involves obtaining plain films, which are two-dimensional images that capture the anatomical structures of the lower jaw, known as the mandible. The selection of views during this examination is tailored to the specific condition being assessed, as various diseases and injuries affecting the jaw can also impact the teeth and their roots. For instance, a dental periapical view is utilized to provide detailed imaging of the teeth and their roots, while a dental occlusal view is particularly useful for evaluating fractures and determining vertical displacement of the mandible. Additionally, a Caldwell or coronal view is employed to assess any horizontal displacement of the mandible. Oblique views are important for examining the ramus angle and the posterior body of the mandible, whereas the Towne view focuses on the condylar and subcondylar regions. It is essential to use 70100 for a partial radiologic examination of the mandible, which is defined as having less than four views. In contrast, for a complete radiologic examination that includes a minimum of four views, the appropriate code is 70110. Following the imaging, the physician reviews the radiographs to identify any abnormalities, such as traumatic injuries, bony projections or growths, and other signs of disease, and subsequently provides a written report detailing the findings.
