What 47536 covers
An interventional radiologist or other qualified physician exchanges a biliary drainage catheter through an existing percutaneous access route, typically under imaging guidance. The service is used when a catheter needs replacement while biliary drainage access remains necessary, such as during a scheduled catheter change or when the existing catheter is obstructed or no longer functioning as intended. Fluoroscopic guidance is included when performed.
Choose this code for an exchange, not for creating new drainage access, changing an external catheter to an internal-external configuration, or simply removing a catheter. The report should identify the existing catheter and access, explain the exchange, and document the replacement catheter’s position and outcome. The code has a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures occur 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; assistant-at-surgery payment is restricted, and co-surgeon and team-surgery billing are not permitted.

47536 billing questions
How is an exchange different from a new catheter placement?
Report 47536 when an existing percutaneous biliary drainage catheter is exchanged through its established access route. Codes 47533 and 47534 describe placement of a drainage catheter rather than exchange.
When should 47535 be considered instead?
Use 47535 for conversion of an external biliary drainage catheter to an internal-external catheter configuration. An exchange that replaces the catheter without that conversion is reported with 47536.
Is catheter removal reported as an exchange?
No. Code 47537 describes percutaneous removal of a biliary drainage catheter; 47536 describes exchange with a replacement catheter.
Is fluoroscopic guidance included?
Fluoroscopic guidance is included when performed. Document the exchange and the replacement catheter’s final position and outcome.
Can modifier 50 or an assistant-at-surgery claim be used?
Modifier 50 is inappropriate for this code. Medicare does not pay an assistant at surgery for this service; co-surgeons and team surgery are not permitted.
What happens when another procedure is performed in the same session?
The highest-valued procedure is paid in full, and other procedures in the same session are subject to the standard multiple procedure reduction.
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.
