CPT® Code 78290

The CPT® Code 78290 refers to a specialized imaging procedure of the intestine, which is utilized for various diagnostic purposes, including the localization of ectopic gastric mucosa, identification of Meckel's diverticulum, and assessment of conditions such as volvulus. This imaging technique employs scintigraphy, a method that utilizes a radiolabeled isotope tracer to visualize internal structures and functions. The tracer can be attached to red blood cells (RBCs) or white blood cells (WBCs), or it may be injected directly into the patient's circulatory system. The primary goal of this procedure is to locate potential bleeding sites, tumors, or areas of inflammation within the bowel. To initiate the procedure, an intravenous line is established, allowing for the direct injection of the radiolabeled isotope tracer into the bloodstream. Alternatively, a blood sample may be collected, which is then processed through centrifugation to separate the RBCs and WBCs. These cells are subsequently tagged with the isotope tracer before being reintroduced into the patient’s body. The choice of using RBCs is typically aimed at identifying sources of bleeding, while WBCs are utilized to detect inflammatory processes. Following the administration of the tracer, the patient is positioned on an imaging table, with a gamma camera placed over the anterior abdomen and pelvis. The imaging process involves scanning at predetermined intervals, during which the radioactive energy emitted from the tracer is captured and converted into detailed images. Advanced imaging techniques such as single-photon emission computed tomography (SPECT), SPECT/CT, and positron emission tomography (PET) may be integrated with scintigraphy to produce enhanced three-dimensional images, providing the physician with comprehensive data for interpretation. Ultimately, the physician analyzes the results of the intestine imaging study and compiles a written report detailing the findings, which is essential for guiding further clinical decisions.
