CPT® Code 74250

Radiologic examination, small intestine, including multiple serial images and scout abdominal radiograph(s), when performed; single-contrast (eg, barium) study

A radiologic examination of the small intestine, designated by CPT® Code 74250, is a diagnostic imaging procedure that utilizes X-ray technology to visualize the duodenum, jejunum, and ileum. This examination is performed using a single-contrast medium, typically barium sulfate, which is ingested by the patient to enhance the visibility of the gastrointestinal tract during imaging. The process involves the use of indirect ionizing radiation, which allows for the capture of images based on the varying densities and compositions of the tissues within the body. As X-rays pass through the body, some are absorbed by denser materials, while others are transmitted, creating a two-dimensional representation of the internal structures on a detector. The primary purpose of this examination is to diagnose various conditions affecting the small intestine, including but not limited to ulcers, tumors, inflammation, scarring, obstructions, and abnormal anatomical configurations. Patients may present with a range of symptoms that warrant this examination, such as unexplained weight loss, the presence of blood in the stool, abdominal pain, indigestion, or abdominal distention. The procedure typically begins with the acquisition of one or more anterior-posterior (AP) scout films, which are taken in either an erect or supine position prior to the administration of the contrast material. The ingestion of the barium sulfate mixture allows for the coating of the gastrointestinal tract, facilitating clearer imaging. The radiologist may also employ fluoroscopic X-ray techniques to visualize the small intestine in real-time, capturing multiple serial images as necessary to assess the function and condition of the area being examined.
