CPT® Code 78201

The procedure described by CPT® Code 78201 involves liver imaging using scintigraphy, which is a nuclear medicine technique that utilizes a radiolabeled isotope tracer, specifically 99mTc-sulfur colloid. This imaging method is primarily employed to assess the liver's size and to identify various abnormalities such as tumors, abscesses, hematomas, or cysts. Additionally, it plays a crucial role in monitoring blood circulation within the liver. The liver, located in the upper right quadrant of the abdomen, is a vital organ responsible for several key functions, including the production of bile, metabolism of nutrients, detoxification of drugs and toxins from the bloodstream, and the synthesis of specific proteins essential for blood plasma and clotting regulation. The liver's structure consists of two main lobes, which are further divided into smaller lobules interconnected by a network of ducts that facilitate the drainage of bile into larger ducts, ultimately leading to the hepatic duct. Bile, produced by the liver, contains enzymes that aid in the breakdown of fats and assist in the transport of waste materials to the gallbladder and duodenum. During the imaging procedure, an intravenous line is established to administer the radiolabeled tracer, followed by a waiting period before the patient is positioned on the imaging table. A gamma camera is then placed over the upper right abdomen to capture images of the liver. The scanning process occurs at specific intervals, during which the radioactive energy emitted from the liver is detected and converted into visual images. It is important to note that for imaging that includes vascular flow assessment, CPT® Code 78202 is utilized instead. The liver's highly vascular nature, characterized by the portal vein and hepatic artery, means that any compromise in one vessel can significantly affect the blood flow in adjacent vessels. After the imaging is completed, the physician interprets the scintigraphy results and generates a comprehensive written report detailing the findings.
