Vascular surgery
About 37140: Open portacaval shunt creation
Reports open creation of a connection between the portal vein and inferior vena cava to decompress portal hypertension, such as in selected patients with variceal bleeding.
A vascular surgeon creates an open connection between the portal venous system and the inferior vena cava, diverting portal blood to reduce portal pressure. The operation is used in selected patients with portal hypertension, including some with recurrent variceal hemorrhage when surgical shunting is chosen. It is a major abdominal procedure, generally performed in a hospital operating room; the operative report should identify the veins connected and describe construction of the shunt.
Report this code for the portacaval route, not a shunt using a different venous connection or an endovascular TIPS procedure. Documentation should establish the anatomy, operative approach, and completed anastomosis. CMS assigns 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% multiple-procedure reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment is statutorily restricted; co-surgeons require supporting documentation, and team surgery is not permitted.

37140 billing questions
How is this code distinguished from other surgical shunt codes?
Use it for an open connection from the portal venous system to the inferior vena cava. A different venous route, such as a renal or mesenteric connection, belongs to its corresponding code.
Is this the code for a TIPS procedure?
No. This code describes an open abdominal portacaval shunt; TIPS is created through an endovascular, transjugular approach.
Can modifier 50 be used for a bilateral procedure?
No. Modifier 50 is inappropriate for this code’s anatomy and descriptor.
What documentation supports reporting the procedure?
The operative report should identify the portal and caval venous anatomy, confirm the open approach, and describe creation of the portacaval anastomosis.
How are assistant and co-surgeon services handled?
Medicare payment for an assistant at surgery is statutorily restricted. Co-surgeon payment requires supporting documentation, and team surgery is not permitted.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and related postoperative care for 90 days.
