What 47712 covers
This code describes surgery to remove a tumor arising in bile ducts within the liver. A hepatobiliary or general surgeon typically performs the procedure in an operating room, often in a hospital setting, when the operative plan includes excision of the intrahepatic duct tumor. The operative report should identify the tumor’s location and describe the ductal tissue removed.
Select this code for an intrahepatic tumor, rather than the extrahepatic tumor service represented by 47711. Documentation should establish the intrahepatic site and the excision performed. The service has a 90-day global period, including the day-before preoperative visit and related postoperative care during that period. 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% multiple-procedure reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment may be available; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

47712 billing questions
How does 47712 differ from 47711?
47712 is for tumor excision involving bile ducts within the liver. 47711 is the corresponding service for an extrahepatic bile duct tumor.
Can modifier 50 be reported?
No. The anatomy and service descriptor make modifier 50 inappropriate for this procedure.
What documentation supports 47712?
The operative report should identify the tumor as involving intrahepatic bile ducts and describe the excision performed. A diagnosis alone does not establish which ductal site was treated.
How does the 90-day global period affect postoperative billing?
The day-before preoperative visit and related postoperative care for 90 days are included in the global period. The code does not represent a separate postoperative visit during that period.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment may be available. Co-surgeon payment requires supporting documentation, and team surgery is not permitted.
