CPT® Code 47525

Deleted

The CPT® Code 47525 refers to the procedure known as the change of percutaneous biliary drainage catheter. This procedure is performed to replace an existing biliary drainage catheter that may be malfunctioning or needs to be updated for various clinical reasons. The process begins with the injection of a small amount of contrast media through the existing catheter. This step is crucial as it confirms the catheter's location within the bile duct, ensuring that the subsequent steps are performed accurately. Following this confirmation, a guidewire is carefully passed through the catheter and into the bile duct, which facilitates the removal of the old catheter. Once the old catheter is removed, a new catheter is introduced over the guidewire and positioned appropriately within the bile duct. After the new catheter is in place, the guidewire is removed, and additional contrast media is injected to verify that the new catheter is correctly positioned and that the bile duct remains patent, meaning it is open and unobstructed. It is important to note that the procedure of exchanging the catheter and the associated contrast injection is captured under this code, while any radiographic supervision and interpretation required during the procedure are reported separately.
