What 47537 covers
An interventional radiologist typically removes a biliary drainage catheter through its existing percutaneous tract when the underlying obstruction or leak has resolved, or internal drainage is adequate. This may follow a successful capping trial or other assessment showing that continued external drainage is unnecessary. The service removes the catheter; it does not describe replacing it or converting it to another catheter configuration. Fluoroscopic guidance associated with removal is included.
Report 47537 for the removal itself, supported by a procedure note documenting the catheter removed, the reason it was no longer needed, and the removal performed. The code has a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate for this service. Medicare does not pay an assistant at surgery, and co-surgeons and team surgery are not permitted.
