1. Indications

The radiologic examination of the upper gastrointestinal tract, as described by CPT® Code 74241, is indicated for a variety of gastrointestinal symptoms and conditions. These include:

• Difficulty swallowing - Patients may experience challenges in swallowing, which can indicate underlying issues in the esophagus or other parts of the upper GI tract.
• Chest or abdominal pain - Unexplained pain in these areas may necessitate imaging to identify potential gastrointestinal disorders.
• Vomiting - Frequent or severe vomiting can be a sign of obstruction or other serious conditions that require evaluation.
• Reflux - Symptoms of gastroesophageal reflux disease (GERD) may prompt the need for imaging to assess the esophagus and stomach.
• Indigestion - Persistent indigestion can be indicative of various gastrointestinal issues that warrant further investigation.
• Blood in the stool - The presence of blood can signal serious conditions such as ulcers or tumors, necessitating a thorough examination of the upper GI tract.

2. Procedure

The procedure for a radiologic examination of the upper gastrointestinal tract with KUB involves several key steps:

• Step 1: Initial Scout Film - The examination begins with the acquisition of a single anteroposterior (AP) scout film. This X-ray is taken from front to back while the patient is positioned either erect or supine. The scout film includes imaging of the kidneys, ureters, and bladder (KUB), providing a baseline view of the abdominal area.
• Step 2: Administration of Contrast Media - Following the scout film, the patient is instructed to orally ingest a contrast medium. This substance is crucial for enhancing the visibility of the upper GI tract structures during imaging.
• Step 3: Fluoroscopic Monitoring - Under fluoroscopy, the movement of the contrast material is monitored as it travels down the esophagus into the stomach and duodenum. This real-time imaging allows for the assessment of the motility and function of the upper GI tract.
• Step 4: Spot Films - As the contrast moves through the gastrointestinal tract, spot films may be taken at specific intervals or locations as indicated by the physician to capture detailed images of areas of interest.
• Step 5: Medication Administration (if necessary) - In some cases, medications may be administered to either accelerate or delay gastrointestinal motility, facilitating a clearer understanding of the contrast's movement through the tract.
• Step 6: Delayed Imaging (if required) - If the movement of the contrast is particularly slow, or to confirm the complete emptying of the contrast from the upper GI tract, delayed images may be obtained to ensure comprehensive evaluation.

3. Post-Procedure

After the completion of the radiologic examination, patients may be monitored for any immediate reactions to the contrast media. It is common for patients to be advised to drink plenty of fluids to help flush the contrast material from their system. Additionally, they may be informed about potential side effects, such as mild abdominal discomfort or changes in bowel habits, which can occur following the procedure. Patients should also be instructed to report any unusual symptoms, such as severe pain or allergic reactions, to their healthcare provider. Follow-up appointments may be scheduled to discuss the results of the examination and any further diagnostic or therapeutic steps that may be necessary based on the findings.
