About 47538: Percutaneous biliary stent placement
Percutaneous placement of a biliary stent in the initial duct to restore bile drainage, typically for an obstructing stricture or other blockage.
An interventional radiologist typically places a stent through a percutaneous, often transhepatic, route to keep an obstructed bile duct open and allow bile to drain. Common clinical settings include biliary strictures and malignant obstruction. Imaging guidance and intraprocedural cholangiography, when performed, are part of the service; the code is for the initial duct treated, not a drainage catheter exchange or removal.
Report this code for stent placement in the initial duct and document the access route, treated duct, obstruction or stricture, and stent placement. Same-day preoperative and postoperative care is included in the 0-day global period. If multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. Modifier 50 is not appropriate for this service. Medicare does not pay for an assistant at surgery, co-surgeons, or team surgery for this code.

47538 billing questions
How does this differ from a biliary drainage catheter placement?
This code is for placing a stent to maintain duct patency. Codes 47533 and 47534 describe placement of biliary drainage catheters, rather than the stent service.
Can the cholangiography or imaging guidance be billed separately?
Imaging guidance and intraprocedural cholangiography, when performed as part of the stent placement, are included in this service.
What supports reporting this code?
Document the percutaneous access, the duct treated, the clinical obstruction or stricture, and placement of the stent in the initial duct.
Should modifier 50 be appended for bilateral duct treatment?
No. CMS identifies bilateral adjustment as inappropriate for this code; report the applicable duct-level service rather than using modifier 50.
How are other procedures in the same session paid?
When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the others are subject to the standard 50% multiple-procedure reduction.
Can an assistant or co-surgeon be reported?
Medicare does not pay for an assistant at surgery for this code, and 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 indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
