What 47801 covers
This service covers placing a support, such as a T-tube or stent, in the extrahepatic bile duct during surgical reconstruction. It is performed by a surgeon, commonly a general or hepatobiliary surgeon, in an operating room. The operative report should identify the reconstruction and describe the support placed and its position in the duct.
Report this code for the support-placement service during reconstruction; code 47800 describes reconstruction of the extrahepatic bile duct itself. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Do not use modifier 50 for bilateral reporting. Assistant-at-surgery payment may be available; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
