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.

47537 billing questions
How is removal different from catheter exchange?
Use 47537 when the biliary drainage catheter is removed without replacement. Use 47536 when an existing biliary drainage catheter is exchanged for another catheter.
Is fluoroscopic guidance separately reported?
Fluoroscopic guidance associated with the percutaneous catheter removal is included in 47537.
Can modifier 50 be used?
No. The service describes removal of a biliary drainage catheter, and modifier 50 is inappropriate.
What does the 0-day global period include?
Same-day preoperative and postoperative care is included in the procedure payment. Care on later dates is outside that same-day global period.
How does Medicare handle other procedures in the same session?
The highest-valued procedure is paid in full, and other procedures in the session are subject to the standard multiple procedure reduction.
May an assistant or co-surgeon be reported?
Medicare does not pay an assistant at surgery for 47537. Co-surgeons and team surgery are not permitted.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
