Official Description

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)

Common Language Description

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.

1. Indications

The procedure associated with CPT® Code 47544 is indicated for the removal of calculi or debris from the biliary ducts and/or gallbladder. The specific indications for this procedure may include:

  • Biliary Stones: Presence of calculi within the biliary ducts or gallbladder that require removal to alleviate symptoms or prevent complications.
  • Failed Endoscopic Extraction: Situations where endoscopic methods for stone removal have been unsuccessful.
  • Patient Refusal of Endoscopy: Cases where the patient has declined endoscopic procedures for personal or medical reasons.

2. Procedure

The procedure for CPT® Code 47544 involves several detailed steps to ensure effective removal of biliary stones. The following procedural steps are outlined:

  • Access Establishment: If a percutaneous transhepatic drainage catheter is already in place, access to the biliary tree or gallbladder can be achieved through this existing catheter. In the absence of a catheter, a small-gauge needle is advanced through the skin and into the liver under fluoroscopic guidance to establish access.
  • Guidewire and Catheter Placement: A guidewire is then advanced transhepatically over the needle, allowing for the manipulation of a catheter to the target area within the biliary duct.
  • Mechanical Removal of Stones: Small stones within the duct may be mechanically removed using a balloon catheter. A stiff guidewire is inserted through the catheter and advanced into the duodenum, followed by the introduction of a sheath over the guidewire. A balloon-tipped catheter is then inserted through the sheath, inflated distal to the stones, and used to dilate the bile duct to the size of the largest stone.
  • Stone Extraction: After deflating the balloon and withdrawing the catheter with its tip placed proximal to the stones, the balloon is reinflated to push the stones through the duct into the duodenum.
  • Use of Cholangioscope: A sheath is introduced through the catheter over the guidewire, and a cholangioscope is advanced to the stone. A basket is passed through the working channel of the cholangioscope to grasp the stones for removal.
  • Fragmentation of Large Stones: For stones that are too large for the diameter of the scope, a lithotripsy probe is inserted through the working channel to fragment the stones. The fragments can then be removed using irrigation and suction or by reintroducing the basket to grasp and remove the fragments.
  • Final Examination: After ensuring that all stones have been removed and that there is no bleeding, the cholangioscope is carefully removed. If a percutaneous transhepatic drainage catheter was used, it is typically replaced at the end of the procedure.

3. Post-Procedure

Post-procedure care following the removal of calculi using CPT® Code 47544 typically involves monitoring the patient for any immediate complications, such as bleeding or infection. Patients may be observed for signs of biliary obstruction or other adverse effects related to the procedure. Follow-up imaging may be required to confirm the successful removal of stones and to assess the condition of the biliary ducts. Additionally, instructions regarding activity restrictions and signs of complications to watch for at home will be provided to the patient. If a percutaneous transhepatic drainage catheter was placed, care instructions for the catheter site will also be given to ensure proper healing and to prevent infection.

52 Reduced services: under certain circumstances a service or procedure is partially reduced or eliminated at the discretion of the physician or other qualified health care professional. under these circumstances the service provided can be identified by its usual procedure number and the addition of modifier 52, signifying that the service is reduced. this provides a means of reporting reduced services without disturbing the identification of the basic service. note: for hospital outpatient reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well-being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use).
53 Discontinued procedure: under certain circumstances, the physician or other qualified health care professional may elect to terminate a surgical or diagnostic procedure. due to extenuating circumstances or those that threaten the well being of the patient, it may be necessary to indicate that a surgical or diagnostic procedure was started but discontinued. this circumstance may be reported by adding modifier 53 to the code reported by the individual for the discontinued procedure. note: this modifier is not used to report the elective cancellation of a procedure prior to the patient's anesthesia induction and/or surgical preparation in the operating suite. for outpatient hospital/ambulatory surgery center (asc) reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use).
59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
