CPT® Code 78261

The CPT® Code 78261 refers to the procedure of gastric mucosa imaging, which utilizes scintigraphy to visualize both normal and ectopic gastric mucosa. This imaging technique employs a radiolabeled isotope tracer, specifically 99mTc-pertechnetate, which is crucial for the identification of various congenital anomalies. These anomalies may include conditions such as Meckel's diverticulum, small bowel duplication, gastric duplication, intrathoracic foregut, and duplication cysts. The procedure begins with the establishment of an intravenous line, through which the radiolabeled isotope tracer is injected into the patient's circulatory system. Following the injection, there is a designated waiting period to allow for the tracer to circulate and accumulate in the gastric mucosa. The patient is then positioned on an imaging table, with the gamma camera placed over the anterior abdomen and chest, if necessary for the study. Scanning is conducted at specific intervals, during which the radioactive energy emitted from the tracer is captured and converted into images. Both normal gastric mucosa and any ectopic areas will show similar accumulation of the radioisotope, allowing for effective comparison. The physician is responsible for interpreting the results of the gastric imaging study and must provide a comprehensive written report detailing the findings.
