Official Description

Injection procedure for percutaneous transhepatic cholangiography

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 47500 refers to the injection procedure for percutaneous transhepatic cholangiography, a diagnostic imaging technique used to visualize the bile ducts. This procedure involves a series of steps that begin with the preparation of the skin and the creation of a small incision at the site where the catheter will be inserted. The typical access points for this procedure are strategically chosen based on the anatomy of the liver; either the right midaxillary line below the tenth rib for accessing the right hepatic lobe or the epigastrium for the left hepatic lobe. A small diameter needle is then carefully inserted through the skin, traversing the liver tissue to reach the bile duct. Once the needle is positioned correctly within the bile duct, a small volume of contrast media is injected to confirm the accurate placement of the needle. Following this confirmation, a guidewire is introduced through the needle into the bile duct, allowing for the removal of the needle. Subsequently, an angiography catheter is advanced over the guidewire, which is then removed. The procedure culminates with the injection of additional contrast media, enabling visualization of the bile ducts through imaging techniques. It is important to note that while this code encompasses the catheter insertion and contrast injection, the radiographic supervision and interpretation of the resulting cholangiogram are billed separately under different codes.

1. Indications

The procedure described by CPT® Code 47500 is indicated for various clinical scenarios where visualization of the bile ducts is necessary. The following conditions may warrant the use of this procedure:

  • Obstructive Jaundice - This condition occurs when there is a blockage in the bile ducts, leading to the accumulation of bile and subsequent jaundice.
  • Biliary Strictures - Narrowing of the bile ducts can occur due to various reasons, including inflammation, scarring, or tumors, necessitating evaluation through cholangiography.
  • Cholelithiasis - The presence of gallstones can lead to complications such as obstruction or infection, making it essential to visualize the bile ducts.
  • Cholangitis - This infection of the bile duct system may require intervention and visualization to assess the extent of the disease.
  • Preoperative Assessment - Prior to surgical procedures involving the biliary system, this imaging technique can provide critical information regarding the anatomy and pathology of the bile ducts.

2. Procedure

The procedure for CPT® Code 47500 involves several critical steps to ensure successful access to the bile ducts. The first step is the preparation of the skin at the chosen incision site, which is typically located over the right midaxillary line below the tenth rib for the right hepatic lobe or over the epigastrium for the left hepatic lobe. After proper antiseptic measures are taken, a small incision is made to facilitate the insertion of a small diameter needle. This needle is then carefully advanced through the skin and into the liver tissue, aiming to reach the bile duct. Once the needle is positioned correctly within the bile duct, a small amount of contrast media is injected. This injection serves a dual purpose: it confirms the accurate placement of the needle within the bile duct and prepares for the subsequent imaging. Following this confirmation, a guidewire is introduced through the needle into the bile duct. The needle is then removed, leaving the guidewire in place. An angiography catheter is subsequently passed over the guidewire, allowing for the guidewire's removal. Finally, additional contrast media is injected through the catheter, enabling visualization of the bile ducts through imaging techniques such as fluoroscopy or X-ray.

3. Post-Procedure

After the completion of the percutaneous transhepatic cholangiography procedure, patients are typically monitored for any immediate complications, such as bleeding or infection at the insertion site. It is essential to assess the patient's vital signs and overall condition during this recovery phase. Depending on the findings from the cholangiogram, further interventions may be necessary, which could include additional imaging studies or therapeutic procedures. Patients may be advised to avoid strenuous activities for a short period following the procedure to allow for proper healing. Follow-up appointments may be scheduled to discuss the results of the cholangiogram and any subsequent treatment plans that may be required based on the findings.
