What 47741 covers
The surgeon creates an internal route for bile to pass from the gallbladder into the bowel. This bypass may be considered when normal drainage is blocked and the gallbladder and its drainage pathway can serve as the source for the anastomosis. It is a major abdominal operation, generally performed by a surgeon in an operating-room setting. The operative report should identify the structures joined and the specific construction performed.
Select 47741 from the documented operation, not solely from a diagnosis such as biliary obstruction. The report should support the gallbladder-to-bowel connection and distinguish it from a connection made directly from a bile duct or liver duct. The service has a 90-day global period, including 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. An assistant at surgery may be paid; co-surgeons require supporting documentation, and team surgery is not permitted. Modifier 50 is inappropriate for this single-anatomy procedure.

How to choose
- 47720Biliary bypass
- Both codes concern gallbladder-to-bowel drainage. Use 47741 only when the operative details meet its specific descriptor; verify the construction documented rather than choosing from the diagnosis.
- 47740Biliary bypass
- This is another gallbladder-to-bowel code in the same group. The operative report's specific construction and associated work determine which code applies.
- 47760Biliary bypass
- 47760 describes a bowel connection originating from bile ducts. For 47741, the gallbladder is the source of the connection.
- 47765Biliary bypass
- 47765 describes a bowel connection originating from liver ducts. Use 47741 when the documented connection originates from the gallbladder.
47741 billing questions
How do I distinguish 47741 from 47760 or 47765?
Follow the anastomosis source documented in the operative report. 47741 concerns a connection from the gallbladder to bowel; 47760 and 47765 concern connections from bile ducts or liver ducts to bowel.
What documentation supports reporting 47741?
The operative report should identify the gallbladder and bowel as the structures joined and describe the construction performed. A diagnosis of obstruction by itself does not establish the procedure.
Does the 90-day global period include postoperative visits?
Yes. The global period includes the day-before preoperative visit and 90 days of related postoperative care.
Can 47741 be reported with another procedure in the same session?
When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the others are subject to the standard 50% reduction. The operative record should support each separately reported procedure.
Which surgical-assistance rules apply?
An assistant at surgery may be paid. Co-surgeons require supporting documentation, and team surgery is not permitted.
Should modifier 50 be used?
No. The single gallbladder-to-bowel anastomosis is not a bilateral procedure, so modifier 50 is inappropriate.
