Official Description

Removal of biliary drainage catheter, percutaneous, requiring fluoroscopic guidance (eg, with concurrent indwelling biliary stents), including diagnostic cholangiography when performed, imaging guidance (eg, fluoroscopy), and all associated radiological supervision and interpretation

Common Language Description

The procedure described by CPT® Code 47537 involves the removal of a percutaneous biliary drainage catheter, which is a tube inserted into the biliary system to facilitate the drainage of bile. This procedure is typically performed after successful decompression of the biliary system and the placement of internal biliary stents. The need for this intervention often arises due to various obstructions in the biliary system, which can be caused by conditions such as gallstones, tumors, infections, inflammation, or trauma. In many cases, the treatment of such obstructions requires a series of staged procedures. Initially, an external biliary catheter may be placed, which can later be converted to an internal-external system. Following this, internal stents are placed to maintain bile flow. After a period of monitoring, typically 1-2 days, the patient returns for fluoroscopic imaging, known as cholangiography, to ensure that the stent is functioning properly and that bile is adequately flowing into the duodenum. Once confirmed, the percutaneous biliary catheter is removed, and the skin incision is closed. The procedure encapsulated by Code 47537 includes all necessary imaging guidance, such as fluoroscopy, as well as the required radiological supervision and interpretation of the images during the catheter removal process.

1. Indications

The procedure associated with CPT® Code 47537 is indicated for patients who require the removal of a percutaneous biliary drainage catheter following the successful management of biliary obstruction. The specific indications for this procedure include:

  • Gallstones - The presence of gallstones can obstruct the bile ducts, necessitating drainage and subsequent catheter removal.
  • Tumors - Tumors in the biliary tract can lead to blockages, requiring the placement of stents and the eventual removal of drainage catheters.
  • Infection - Infections in the biliary system may require drainage to alleviate symptoms and prevent complications.
  • Inflammation - Inflammatory conditions affecting the biliary system can cause obstructions that necessitate catheter placement and removal.
  • Trauma - Biliary trauma may result in the need for drainage procedures, followed by catheter removal once the situation is stabilized.

2. Procedure

The procedure for the removal of a percutaneous biliary drainage catheter involves several critical steps, which are detailed as follows:

  • Step 1: Patient Preparation - The patient is prepared for the procedure, which includes obtaining informed consent and ensuring that all necessary imaging equipment is available. The patient may be positioned appropriately to facilitate access to the biliary system.
  • Step 2: Imaging Guidance - Fluoroscopic guidance is employed to visualize the biliary system and confirm the position of the indwelling stent and catheter. This imaging is crucial for ensuring the safe removal of the catheter.
  • Step 3: Cholangiography - If performed, diagnostic cholangiography is conducted to assess the patency of the biliary system and the functionality of the stent. This step helps to confirm that bile is flowing correctly into the duodenum.
  • Step 4: Catheter Removal - Once the imaging confirms that the stent is functioning properly, the percutaneous biliary drainage catheter is carefully removed. This step must be performed with precision to avoid any complications.
  • Step 5: Closure - After the catheter is removed, the skin incision is closed appropriately. This may involve suturing or other closure techniques to ensure proper healing.

3. Post-Procedure

Post-procedure care following the removal of the percutaneous biliary drainage catheter includes monitoring the patient for any signs of complications, such as infection or bleeding at the incision site. Patients are typically observed for a short period to ensure that they are stable and that the biliary system is functioning as expected. Follow-up imaging may be scheduled to confirm the continued patency of the biliary system and the proper function of the stent. Patients are also advised on signs and symptoms to watch for that may indicate complications, and instructions for care at the incision site are provided to promote healing.

22 Increased procedural services: when the work required to provide a service is substantially greater than typically required, it may be identified by adding modifier 22 to the usual procedure code. documentation must support the substantial additional work and the reason for the additional work (ie, increased intensity, time, technical difficulty of procedure, severity of patient's condition, physical and mental effort required). note: this modifier should not be appended to an e/m service.
51 Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d).
58 Staged or related procedure or service by the same physician or other qualified health care professional during the postoperative period: it may be necessary to indicate that the performance of a procedure or service during the postoperative period was: (a) planned or anticipated (staged); (b) more extensive than the original procedure; or (c) for therapy following a surgical procedure. this circumstance may be reported by adding modifier 58 to the staged or related procedure. note: for treatment of a problem that requires a return to the operating/procedure room (eg, unanticipated clinical condition), see modifier 78.
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.
76 Repeat procedure or service by same physician or other qualified health care professional: it may be necessary to indicate that a procedure or service was repeated by the same physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 76 to the repeated procedure or service. note: this modifier should not be appended to an e/m service.
78 Unplanned return to the operating/procedure room by the same physician or other qualified health care professional following initial procedure for a related procedure during the postoperative period: it may be necessary to indicate that another procedure was performed during the postoperative period of the initial procedure (unplanned procedure following initial procedure). when this procedure is related to the first, and requires the use of an operating/procedure room, it may be reported by adding modifier 78 to the related procedure. (for repeat procedures, see modifier 76.)
79 Unrelated procedure or service by the same physician or other qualified health care professional during the postoperative period: the individual may need to indicate that the performance of a procedure or service during the postoperative period was unrelated to the original procedure. this circumstance may be reported by using modifier 79. (for repeat procedures on the same day, see modifier 76.)
