Biliary imaging
About 47531: Cholangiogram Through Existing Catheter
Reports contrast injection through an existing biliary catheter to outline the bile ducts, with fluoroscopic imaging and interpretation included.
This service uses an existing percutaneous biliary catheter to inject contrast and image the biliary tree under fluoroscopy. It can show duct anatomy, catheter position, or whether contrast passes through the ducts and into the bowel. Interventional radiologists and other physicians performing image-guided biliary procedures commonly provide it in a hospital or outpatient interventional setting. The code includes fluoroscopic guidance, image documentation, and the imaging report.
Report 47531 when the injection is performed through an already established catheter; use 47532 when the cholangiogram is performed through newly created access. The record should identify the existing catheter, document the contrast injection and fluoroscopic findings, and support the medical reason for imaging. This is a minor procedure with 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 multiple procedure reduction. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery for this service; co-surgeons and team surgery are not permitted.

47531 billing questions
When should 47531 be chosen over 47532?
Use 47531 for contrast injection through a catheter already in place. Use 47532 when the cholangiogram is performed through newly created access.
Is fluoroscopic guidance separately reported?
No. Fluoroscopic guidance, image documentation, and the imaging report are included in 47531.
Can modifier 50 be appended?
No. The bilateral adjustment does not apply to this code, and modifier 50 is inappropriate.
How does the multiple procedure rule affect payment?
For procedures performed in the same session, the highest-valued procedure is paid in full and the other procedures are subject to the standard multiple procedure reduction.
What documentation supports reporting 47531?
Document that an existing biliary catheter was used, the contrast injection and fluoroscopic findings, and the clinical purpose of the study.
