CPT® Code 78262

The gastroesophageal reflux study, identified by CPT® Code 78262, is a diagnostic imaging procedure primarily utilized in infants and children to evaluate gastroesophageal reflux (GER). This condition is characterized by the abnormal retrograde movement of gastric contents, including acid and other secretions, from the stomach back into the esophagus. The study employs a radiolabeled isotope tracer, specifically 99mTc-sulfur colloid, which is a safe and effective radioactive substance used to visualize the movement of materials within the gastrointestinal tract. During the procedure, the isotope tracer is mixed with a liquid, commonly milk or orange juice, which the patient ingests. The patient is then positioned on an imaging table, with a gamma camera strategically placed over the anterior chest and abdomen to capture detailed images. Scanning occurs at predetermined intervals, allowing for the observation of the tracer's transit through the esophagus into the stomach, and subsequently monitoring for any reflux back into the esophagus. In cases where pulmonary aspiration is a concern, additional imaging of the lungs may be performed to assess any potential complications. The emitted radioactive energy from the tracer is transformed into images that can provide a semi-quantitative assessment of the reflux volume. Following the completion of the study, a physician interprets the results and generates a comprehensive written report detailing the findings, which is essential for guiding further clinical management of the patient.
