CPT® Code 47544

Add-On Code

Removal of calculi/debris from biliary duct(s) and/or gallbladder, percutaneous, including destruction of calculi by any method (eg, mechanical, electrohydraulic, lithotripsy) when performed, imaging guidance (eg, fluoroscopy), and all associated radiological supervision and interpretation (List separately in addition to code for primary procedure)

The procedure described by CPT® Code 47544 involves the removal of calculi or debris from the biliary ducts and/or gallbladder using a percutaneous approach. This minimally invasive technique is particularly beneficial for managing biliary stones when traditional endoscopic extraction methods are either unsuccessful or declined by the patient. The term "percutaneous" refers to the method of accessing the biliary system through the skin, which allows for a less invasive alternative to open surgery. The procedure may involve various techniques for the destruction of stones, including mechanical methods, electrohydraulic techniques, or lithotripsy, which is a method that uses shock waves to break stones into smaller pieces. Imaging guidance, such as fluoroscopy, is utilized throughout the procedure to ensure accurate placement of instruments and to visualize the biliary tree. This imaging is crucial for the safe and effective removal of stones, as it allows the physician to monitor the progress of the procedure in real-time. Additionally, the code encompasses all associated radiological supervision and interpretation, ensuring that the imaging aspects of the procedure are fully accounted for in the coding process. Overall, CPT® Code 47544 captures the comprehensive nature of this procedure, which includes not only the removal of stones but also the necessary imaging and supervision required to perform it safely and effectively.
