CPT code 47741: Biliary bypass, gallbladder to bowel2026 Medicare rate & RVUs

Medicare pays $1,384.80 for 47741 nationally in a facility.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

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.
