Interventional radiology
About 47533: Percutaneous external biliary drain placement
Percutaneous placement of an external biliary drainage catheter to divert bile when normal drainage through the biliary tract is impaired.
An interventional radiologist typically places this catheter through the skin and liver into the biliary system, using imaging to guide access and catheter positioning. The external catheter directs bile out of the body into a collection bag, commonly to relieve obstruction from a stricture, stone, or tumor when external drainage is needed. Diagnostic cholangiography and imaging guidance are included when performed, along with the associated radiological supervision and interpretation.
Report 47533 for initial placement of an external drain; use 47534 when the catheter provides internal-external drainage. The record should support the access, catheter placement, drainage approach, and clinical need. The 0-day global includes same-day preoperative and postoperative care. In a same-session multiple-procedure claim, the highest-valued procedure is paid in full and other procedures at 50%. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery, and co-surgeons and team surgery are not permitted.
