CPT® Code 76100

A radiologic examination of a single plane body section, as described by CPT® Code 76100, involves the use of imaging technology to create a two-dimensional representation of various body structures. This procedure is performed without the use of contrast agents, allowing for the visualization of soft tissues, air-filled cavities, bones, foreign bodies, or radiopaque substances such as barium. The examination relies on the differential absorption of x-rays by different types of tissues, which results in a radiographic image that displays varying degrees of density. In this context, air is the least dense material and appears the lightest on the image, while fat, soft tissues (including organs and muscles), calcific tissues (like bones), and tooth enamel follow in increasing density. Foreign bodies and radiopaque contrast materials, which are denser, will appear the darkest on the radiographic film. It is important to note that this code specifically excludes examinations performed with urography, focusing instead on the assessment of other body sections.
