CPT® Code 78802

Radiopharmaceutical localization of tumor, inflammatory process or distribution of radiopharmaceutical agent(s) (includes vascular flow and blood pool imaging, when performed); planar, whole body, single day imaging

The CPT® Code 78802 refers to a diagnostic procedure known as radiopharmaceutical localization of tumors or inflammatory processes, which utilizes molecular imaging techniques. This procedure involves the use of scintigraphy, a method that employs a radiolabeled isotope tracer to identify and localize areas of inflammation or tumors within the body. The radiopharmaceutical agent is designed to bind to specific biological targets, allowing for the detection of pathological changes, even in their early stages. The process begins with the establishment of an intravenous line, through which the radiolabeled isotope tracer is injected directly into the patient's circulatory system. Alternatively, a blood sample may be taken, processed to separate the blood cells, and then tagged with the isotope before being reintroduced into the patient. In some cases, radioactive agents may also be administered via inhalation or ingestion, depending on the target area of interest. Once the tracer is in circulation, it travels throughout the body, localizing in areas of tumorous or inflamed tissue. The patient is then positioned on an imaging table, and a gamma camera is used to scan the targeted area, capturing images based on the radioactive energy emitted from the tracer. This imaging can include vascular flow and blood pool imaging, providing comprehensive insights into the distribution of the radiopharmaceutical agent. The resulting images are static, two-dimensional representations that the physician interprets to generate a detailed report of the findings. It is important to note that CPT® Code 78802 specifically pertains to whole body planar imaging conducted on a single day, distinguishing it from other related codes that cover imaging of single or multiple areas over varying time frames.
