About 47701: Bile duct anastomosis revision
Revision of a previously created bile duct anastomosis without reconstruction, typically to address a narrowed, leaking, or dysfunctional surgical connection.
47701 describes operative revision of an existing bile duct anastomosis while retaining the existing connection rather than creating a reconstruction. A surgeon may revise a narrowed or otherwise dysfunctional biliary-enteric junction after prior biliary surgery. The work is performed in an operating room and involves surgically correcting the anastomosis, not simply inspecting the bile duct. The operative report should identify the prior connection and the revision performed.
Choose this code when the surgeon revises the existing anastomosis without reconstruction; use the related reconstruction code when the operative work includes reconstruction. Document the indication, anatomy, surgical changes, and whether reconstruction was performed. The 90-day global includes the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in one session, the highest-valued procedure is paid in full and the others at 50%. Modifier 50 is inappropriate for this anastomosis. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

47701 billing questions

What documentation supports reporting 47701?
