What 47532 covers
A physician injects contrast through an established route into the biliary system and obtains cholangiographic images. The route may be an existing biliary catheter or other established access. Interventional radiologists commonly perform this service in a hospital or outpatient procedural setting to assess duct anatomy, drainage, or a suspected obstruction. Fluoroscopy, when used, is part of the service.
Choose this code when imaging is performed through existing access, rather than by establishing new percutaneous access. The record should identify the access route, document the contrast injection and imaging, and include the clinical reason and findings. Same-day preoperative and postoperative care is included in the 0-day global service. When multiple procedures occur in one session, Medicare pays the highest-valued procedure in full and reduces the others to 50%. The biliary anatomy is not treated as a paired bilateral service, so modifier 50 is not appropriate. Medicare does not pay an assistant at surgery for this service, and does not permit co-surgeon or team-surgery payment.

- 47533Biliary drainageExternal catheter
- 47533 describes biliary drainage catheter placement, not an injection-only cholangiogram through existing access.
- 47536Biliary catheter exchangePercutaneous

47532 billing questions
How is 47532 different from 47531?
47532 is for cholangiographic injection through access that is already established. Use 47531 when the service involves percutaneous transhepatic access for the cholangiogram.
Is fluoroscopy separately reported?
Fluoroscopy, when performed as part of this injection service, is included. The documentation should support the contrast injection and resulting biliary imaging.
Can 47532 be reported for placing a biliary drain?
No. Drain placement is a different service; select the applicable placement code when a catheter is placed. This code describes imaging through existing access.
What should the record show to support 47532?
Document the pre-existing access route, contrast injection, cholangiographic imaging, clinical indication, and findings. The record should distinguish this work from new access or catheter placement.
Can modifier 50 be used for bilateral ducts?
No. The service is not treated as a paired bilateral procedure, and modifier 50 is inappropriate.
How does Medicare handle other procedures performed in the same session?
Under the standard multiple procedure reduction, Medicare pays the highest-valued procedure in full and reduces the other procedures to 50%. Same-day preoperative and postoperative care is included in this code's 0-day global period.
