CPT® Code 78216

The procedure described by CPT® Code 78216 involves imaging of the liver and spleen utilizing scintigraphy, a diagnostic technique that employs a radiolabeled isotope tracer, specifically 99mTC-sulfur colloid. This imaging is crucial for assessing the size and condition of these organs, as it aids in the identification of various abnormalities such as tumors, abscesses, hematomas, cysts, and hypersplenism. Additionally, it helps in detecting the radiocolloid shift that may occur due to hepatic dysfunction or portal hypertension. The process begins with the establishment of an intravenous line through which the radiolabeled isotope tracer is administered directly into the patient's circulatory system. Alternatively, a blood sample may be taken, and the tracer is attached to heat-destroyed red blood cells (RBCs) before being reintroduced into the body. Following a designated waiting period, the patient is positioned on an imaging table, with a gamma camera placed over the upper abdomen to capture the images. The scanning process is conducted at specific intervals, during which the radioactive energy emitted from the liver and spleen is detected and converted into visual images. This procedure is particularly significant as both the liver and spleen are highly vascular organs, meaning that any compromise in the blood vessels of one organ can lead to alterations in blood flow in the surrounding organs. The physician is responsible for interpreting the scintigraphy results and providing a comprehensive written report detailing the findings.
