CPT® Code 71101

The CPT® Code 71101 refers to a radiologic examination of the ribs on one side of the body, specifically a unilateral examination. This procedure includes a posteroanterior (PA) view and requires a minimum of three distinct views to be captured. Rib radiographs, commonly known as X-rays, are essential diagnostic tools typically utilized following trauma to the rib cage. The primary purpose of these radiographs is to assess for potential fractures or other internal injuries that may not be immediately visible through physical examination alone. The standard views employed during this examination include the anteroposterior (AP) view, which is a frontal view, and various oblique views. The oblique views are obtained by positioning the patient in specific orientations: right anterior oblique, left anterior oblique, right posterior oblique, and left posterior oblique. For anterior oblique views, the patient stands with their chest rotated at a 45-degree angle, with the arm closest to the X-ray cassette flexed and resting on the hip, while the opposite arm is raised. This positioning allows for optimal visualization of the ribs on the side being examined. Conversely, posterior oblique views are generally reserved for patients who are unable to stand or lie prone due to illness. In comparison to other related codes, such as CPT® 71100, which captures two images of the ribs on one side, CPT® 71101 specifically requires three images, ensuring a more comprehensive assessment. The PA view, where the patient's back faces the X-ray machine, is crucial for accurate interpretation. Other codes, such as CPT® 71110 and CPT® 71111, involve bilateral examinations with varying numbers of views. Ultimately, the physician reviews the obtained images, identifies any abnormalities, and provides a detailed written interpretation of the findings, which is essential for guiding further clinical management.
