What 47701 covers

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.

How to choose

47700Bile duct exploration
47700 describes exploration of the bile ducts. It is not the code for operative revision of a prior anastomosis.
47760Biliary bypass
47760 describes creating a connection between extrahepatic bile ducts and the gastrointestinal tract; 47701 revises an existing connection without reconstruction.
47765Biliary bypass
47765 describes creating a connection between liver ducts and the gastrointestinal tract, rather than revising an existing bile duct anastomosis.

47701 billing questions

How is 47701 distinguished from 47702?

Use 47701 for revision of the existing bile duct anastomosis without reconstruction. When the operative work includes reconstruction, consider 47702 instead.

Does 47701 include the related postoperative visits?

Yes. Its 90-day global includes the day-before preoperative visit and 90 days of related postoperative care.

Can modifier 50 be used for a bilateral revision?

No. Modifier 50 is inappropriate for revision of a bile duct anastomosis; the service is not a paired bilateral procedure.

When may an assistant-at-surgery be reported?

Assistant-at-surgery payment is available only when the record documents medical necessity. Co-surgeon and team-surgery billing are not permitted for this code.

What documentation supports reporting 47701?

Document the preexisting anastomosis, the reason it required revision, the operative work performed, and whether reconstruction was performed.

How are multiple procedures in the same session paid?

The highest-valued procedure is paid in full, with the other procedures paid at 50% when performed in the same session.

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.
