Biliary surgery
About 47721: Cholecystoenterostomy with gastroenterostomy
A combined bypass connecting the gallbladder and stomach to intestine, reported when both anastomoses are created during the same operation.
This operation creates two intestinal connections: one from the gallbladder to the bowel to divert bile, and another from the stomach to the bowel to bypass an obstruction. It may be used in abdominal surgery when both biliary drainage and passage of stomach contents need surgical bypass, such as in selected patients with advanced pancreatic or periampullary disease. The surgeon’s operative report should establish that both connections were performed and identify the anatomy used.
Report the combined service when the operation includes both the gallbladder-to-bowel and stomach-to-bowel anastomoses. The major-surgery 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 the others at 50%. Modifier 50 is inappropriate for this code. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

47721 billing questions
When is this code preferable to 47720?
Use this code when the operation includes both a gallbladder-to-bowel connection and a stomach-to-bowel connection. Code 47720 represents a gallbladder-to-bowel bypass without that combined gastric bypass service.
Can the gastroenterostomy be reported separately?
This code represents the combined operation, including both connections. The operative report should document each anastomosis rather than describing only a biliary bypass.
Should modifier 50 be appended?
No. The anatomy and service represented by this code make bilateral reporting with modifier 50 inappropriate.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment may be made. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
