What 47555 covers
A physician passes an endoscope through a percutaneous tract into the biliary tree and removes foreign material. This may be performed by an interventional radiologist when an object or device fragment remains in the ducts after prior biliary access or treatment. The service is distinct from routine exchange or removal of a biliary drainage catheter and from endoscopic extraction of duct stones, which have separate codes.
Report the service when the procedure documentation supports endoscopic access and removal of foreign material; identify the access route and the material removed. The 0-day global period includes same-day preoperative and postoperative care. When related endoscopies are performed together, CMS applies endoscopy-family pricing. Modifier 50 is inappropriate for this service. CMS does not pay for an assistant at surgery, co-surgeons, or team surgery for this code.
