What 47740 covers
The surgeon creates an anastomosis between the gallbladder and intestine so bile can drain around an obstruction. This may be considered when the gallbladder can serve as the drainage conduit, such as in selected patients with distal biliary obstruction. The operation is generally performed by a general or hepatobiliary surgeon in a hospital operating room. The operative report should identify the structures joined and describe the reconstruction performed.
Choose this code from the documented operative configuration, not merely from the diagnosis or the fact that bile drainage was restored. Distinguish it from procedures joining the bile duct or hepatic ducts directly to bowel, and review related gallbladder-to-bowel codes against the full operative details. CMS assigns 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 others are subject to the standard multiple-procedure reduction. Modifier 50 is inappropriate for this anatomy. Assistant-at-surgery payment may be allowed; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

47740 billing questions
What operative details support reporting this code?
The operative report should document that the surgeon connected the gallbladder to intestine and describe the reconstruction. The diagnosis alone does not establish which gallbladder-to-bowel code applies.
How does this differ from a bile-duct-to-bowel bypass?
This service uses the gallbladder as the structure joined to intestine. A bypass joining the bile duct or hepatic ducts directly to bowel is coded according to that anatomy instead.
Is modifier 50 appropriate?
No. CMS identifies bilateral adjustment as inappropriate for this code because of the descriptor or anatomy.
How does the 90-day global period affect related care?
The day-before preoperative visit and 90 days of related postoperative care are included in the global period.
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.
What happens when another procedure is performed in the same session?
Under the standard multiple-procedure rule, the highest-valued procedure is paid in full and other procedures are subject to a 50% reduction.
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.
