What 47552 covers
An interventional radiologist typically passes an endoscope through an established percutaneous biliary tract to inspect the ducts, often while evaluating a stricture, unexplained obstruction, or suspected intraductal lesion. The service may include collecting cells with brushings or washings. It uses existing access rather than creating a new tract, and is generally performed in a hospital procedural setting.
Report this code when the documented service is diagnostic endoscopy through that existing access; brushings or washings are included when performed. A biopsy is distinguished from brush or wash sampling and may point to code 47553. The code has a 0-day global period, so same-day preoperative and postoperative care is included. In a same-session multiple-procedure claim, the highest-valued procedure is paid in full and other procedures are subject to the 50% reduction. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
