Hepatobiliary ductal system imaging, including gallbladder, with or without pharmacologic intervention, with or without quantitative measurement of gallbladder function

The CPT® Code 78223 refers to a diagnostic imaging procedure known as hepatobiliary ductal system imaging. This procedure involves the use of radioactive aminoacetic acids, which are injected into the patient to visualize the gallbladder and the associated bile ducts. The imaging is conducted using a specialized camera that captures a series of images as the radioactive substances are metabolized by the liver and subsequently expelled through the bile duct. The primary purpose of this procedure is to assess the functionality of the bile ducts and the gallbladder, providing critical information regarding any potential obstructions, dysfunctions, or abnormalities within the hepatobiliary system. The procedure may also include pharmacologic interventions to enhance the imaging process and may involve quantitative measurements of gallbladder function, allowing for a comprehensive evaluation of the patient's hepatobiliary health.
