What 47570 covers
This operation uses laparoscopic access to connect the gallbladder to a segment of intestine, creating a route for bile to drain around an obstruction in its usual outflow pathway. A general or hepatobiliary surgeon may perform it when the gallbladder and cystic duct can provide a usable source of drainage. It is an uncommon reconstructive operation, generally performed in an operating room under general anesthesia; the gallbladder remains part of the bypass.
Select this code for the laparoscopic bypass, not for removal of the gallbladder. The operative report should identify the indication, laparoscopic approach, intestinal connection, and anatomy supporting the bypass. Medicare assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in one session, the highest-valued procedure is paid in full and others at 50%. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

47570 billing questions
How does this differ from laparoscopic cholecystectomy?
This code is for creating a drainage connection between the gallbladder and intestine while retaining the gallbladder. Laparoscopic cholecystectomy codes describe gallbladder removal.
What should the operative report document?
Document the biliary indication, laparoscopic technique, gallbladder and intestinal anatomy, and the connection created. The record should make clear that the operation establishes a bypass rather than removing the gallbladder.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
How are other procedures in the same session paid?
Under the standard multiple procedure reduction, the highest-valued procedure is paid in full and the other procedures are paid at 50%.
Can an assistant or co-surgeon be reported?
An assistant at surgery may be paid. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
