CPT® Code 71100

The CPT® Code 71100 refers to a radiologic examination of the ribs, specifically a unilateral examination that includes two views. This procedure is commonly performed to assess the rib cage following trauma, with the primary goal of identifying any fractures or internal injuries that may not be immediately visible. Rib radiographs, or X-rays, are essential diagnostic tools in emergency and trauma settings, as they help clinicians evaluate the integrity of the rib structure and surrounding tissues. The two standard views utilized in this examination are the anteroposterior (AP) view, which captures a frontal image of the ribs, and an oblique view, which provides a different angle to enhance visualization of potential injuries. In the oblique views, the patient is positioned at a 45-degree angle to the X-ray cassette, allowing for a comprehensive assessment of the ribs on the side being examined. The procedure is designed to ensure that the area of interest is adequately imaged, facilitating accurate diagnosis and subsequent management. The distinction between this code and related codes, such as 71101, 71110, and 71111, lies in the number of views obtained and whether the examination is unilateral or bilateral. The physician is responsible for reviewing the resulting images, identifying any abnormalities, and documenting a written interpretation of the findings, which is crucial for guiding further clinical decisions.
