CPT® Code 47505

Deleted

The CPT® Code 47505 refers to an injection procedure specifically designed for cholangiography, which is a diagnostic imaging technique used to visualize the bile ducts. This procedure is performed through an existing catheter, such as a percutaneous transhepatic drainage catheter or a T-tube, which has already been placed in the patient. The primary purpose of this injection is to introduce contrast media into the bile ducts, allowing for enhanced visualization during imaging studies. This is particularly important for diagnosing conditions affecting the biliary system, such as obstructions, strictures, or other abnormalities. It is essential to note that this code pertains solely to the injection of contrast media and does not include the radiographic supervision and interpretation of the cholangiogram, which must be reported separately. The use of an existing catheter streamlines the procedure, as it eliminates the need for additional invasive access to the bile ducts, thereby reducing patient risk and discomfort while still providing critical diagnostic information.
