Official Description

Liver function study with hepatobiliary agents, with serial images

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 78220 refers to a liver function study that utilizes hepatobiliary agents, specifically radioactive aminoacetic acids, to assess liver function. During this procedure, a physician administers these agents to the patient, which are then processed by the liver. The study involves capturing a series of images using a specialized camera that tracks the movement and processing of these agents as they are expelled through the bile duct. This imaging technique is crucial for evaluating the liver's functionality and can help identify any abnormalities or issues related to liver health. The procedure is non-invasive and provides valuable insights into the liver's ability to perform its essential functions, including the production of bile and the metabolism of various substances.

1. Indications

The liver function study with hepatobiliary agents is indicated for various clinical scenarios where assessment of liver function is necessary. The following conditions may warrant this procedure:

  • Evaluation of Liver Function: This study is performed to assess the overall functionality of the liver, particularly in patients with suspected liver disease.
  • Investigation of Biliary Obstruction: It helps in identifying any blockages in the bile ducts that may affect the liver's ability to expel bile.
  • Monitoring Liver Disease Progression: The procedure can be used to monitor changes in liver function over time in patients with known liver conditions.
  • Assessment of Hepatic Circulation: It evaluates the blood flow to and from the liver, which is essential for diagnosing various hepatic conditions.

2. Procedure

The procedure for the liver function study with hepatobiliary agents involves several key steps that ensure accurate imaging and assessment of liver function. The following outlines the procedural steps:

  • Step 1: Patient Preparation The patient is prepared for the procedure, which may include fasting for a specified period prior to the injection of the radioactive agents. This preparation is essential to ensure optimal imaging results.
  • Step 2: Injection of Hepatobiliary Agents The physician administers radioactive aminoacetic acids intravenously. These agents are specifically chosen for their ability to be processed by the liver and subsequently expelled through the bile ducts.
  • Step 3: Imaging Acquisition After the injection, a series of images are captured using a specialized gamma camera. This imaging process tracks the distribution and movement of the radioactive agents within the liver and biliary system over time.
  • Step 4: Image Analysis The images obtained are analyzed to assess liver function, including the liver's ability to uptake and excrete the radioactive agents. This analysis helps in identifying any abnormalities in liver function or biliary obstruction.

3. Post-Procedure

After the liver function study is completed, patients are typically monitored for a short period to ensure there are no immediate adverse reactions to the radioactive agents. Patients may be advised to hydrate adequately to facilitate the excretion of the radioactive material from their system. Follow-up appointments may be scheduled to discuss the results of the imaging study and any further diagnostic or therapeutic steps that may be necessary based on the findings.
