What 47760 covers
The surgeon creates an anastomosis between the common bile duct and intestine so bile can drain into the bowel. This may be performed for biliary obstruction or injury when the usual route of drainage cannot be maintained. General and hepatobiliary surgeons typically perform the operation in a hospital operating room; Medicare’s 2024 claims data show facility services for this code and none in the office setting.
Select the code when the operative report documents the common bile duct as the duct joined to the intestine. Record the duct and bowel anatomy, the reason for bypass, and the completed anastomosis; a connection from a hepatic duct or the gallbladder is distinguished by its source anatomy. The code 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 one session, the highest-valued procedure is paid in full and the others at 50%. Modifier 50 is inappropriate. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

- 47780Biliary reconstructionExtrahepatic duct, Roux-en-Y
- Use 47780 for a bile duct-to-duodenum connection. This code describes a choledochoenterostomy without that specific duodenal anatomy.
- 47720Biliary bypassGallbladder to bowel
- Code 47720 uses the gallbladder to establish drainage into bowel; this code uses the common bile duct.
47760 billing questions
How is this code distinguished from a hepaticojejunostomy?
Use the documented anastomosis anatomy: this code is for a connection from the common bile duct to intestine. A connection originating from a hepatic duct is represented by the hepaticojejunostomy code, 47765.
Is this code appropriate for a bile duct-to-duodenum connection?
Code 47780 describes the bile duct-to-duodenum procedure. Use this code when the documented procedure is a choledochoenterostomy other than that specifically identified anatomy.
Can modifier 50 be used for a bilateral procedure?
No. CMS identifies bilateral adjustment as inappropriate for this code because of its descriptor or anatomy.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and related postoperative care for 90 days. The operative report should support the bypass and the anatomy involved.
How are other procedures performed in the same session paid?
Under the standard multiple procedure reduction, the highest-valued procedure is paid in full and other procedures are paid at 50%. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
