CPT® Code 47532

Injection procedure for cholangiography, percutaneous, complete diagnostic procedure including imaging guidance (eg, ultrasound and/or fluoroscopy) and all associated radiological supervision and interpretation; new access (eg, percutaneous transhepatic cholangiogram)

The CPT® Code 47532 refers to a specific injection procedure known as percutaneous transhepatic cholangiography, which is a complete diagnostic procedure aimed at visualizing the bile ducts. This procedure is essential for diagnosing blockages or abnormalities within the bile duct system. During the process, imaging guidance is utilized, which may include ultrasound and/or fluoroscopy, to ensure accurate placement of instruments and to visualize the bile ducts effectively. The procedure involves creating a new access point, typically through the skin, to allow for the introduction of a catheter into the bile duct. This access is crucial for the injection of contrast medium, which helps in delineating the anatomy of the bile ducts and identifying any obstructions or issues present. The procedure is performed under radiological supervision, ensuring that all imaging is interpreted correctly to provide a comprehensive assessment of the patient's condition. The detailed steps involved in this procedure are critical for medical coders and billers to understand, as they directly relate to the coding and billing processes associated with diagnostic imaging and interventions in the biliary system.
