About 37160: Open portal-systemic shunt revision
Report this code for open revision of an existing portal-systemic venous shunt, rather than creation of a new shunt or endovascular TIPS revision.
This code describes open surgical revision of an existing portal-systemic venous shunt, a surgically created route that diverts portal blood into the systemic venous circulation. The operation addresses a problem with the existing shunt, such as impaired flow, and is distinct from creating a new shunt or revising a transjugular intrahepatic portosystemic shunt (TIPS). Vascular or transplant surgeons typically perform the operation in a hospital operating room for patients with portal hypertension or a shunt complication.
Select the code when the operative report documents revision of the existing portal-systemic shunt and identifies the anatomy and work performed. The code has a 90-day global period, including the day-before preoperative visit and related postoperative care during that period. 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. 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.
