A radiological examination of the upper gastrointestinal (GI) tract, identified by CPT® Code 74247, involves the use of advanced imaging techniques to visualize the esophagus, stomach, and duodenum, which is the initial segment of the small intestine. This procedure employs X-ray imaging, a method that utilizes indirect ionizing radiation to capture images of the body's internal structures. The principle behind this imaging technique is based on the varying densities and compositions of human tissues, which allow certain X-rays to be absorbed while others pass through. The resulting images are two-dimensional representations of the anatomical structures being examined.

The primary purpose of this examination is to diagnose a range of gastrointestinal conditions, including but not limited to ulcers, tumors, inflammation, hiatal hernias, scarring, obstructions, and any abnormal positioning or configuration of the organs. Patients typically present with various symptoms that may prompt this examination, such as difficulty swallowing, chest or abdominal pain, vomiting, reflux, indigestion, or the presence of blood in the stool.

The procedure generally commences with an initial scout film, known as a KUB (Kidneys, Ureters, and Bladder), which is obtained in either an erect or supine position. This initial imaging captures the kidneys, ureters, and bladder, providing a baseline for further examination. For the air contrast study, the patient ingests a specific high-density barium sulfate mixture, which coats the esophagus and stomach, while also facilitating the buildup of air in the stomach as it is digested. Additionally, glucagon may be administered to relax the muscles in the area being examined, enhancing the clarity of the images obtained.

X-ray images of the esophagus and stomach are captured as needed, and in some cases, delayed images may be required to assess the movement of the contrast material or to confirm the emptying of the stomach. It is important to note that not all images from this procedure may be available for immediate viewing, and the interpretation of these images is crucial for accurate diagnosis and treatment planning.
