Inferior Mesenteric Vein Excision Procedure Overview

This procedure group includes excision procedures that remove a portion of the inferior mesenteric vein within the lower veins body system. These operations involve cutting out or off part of the vein without replacement and are performed to treat venous pathology or facilitate other intra-abdominal procedures. Accurate ICD-10-PCS coding of these excisions supports proper inpatient documentation and reimbursement by reflecting the specific body part and operation performed.

Typical Clinical Scenarios

An elderly patient presents urgently with lower abdominal sepsis from a strangulated sigmoid colon tumor with venous invasion and active bleeding into the mesentery; during the emergent laparotomy the surgeon excises the involved segment of the inferior mesenteric vein to control hemorrhage and remove tumor-invaded tissue. This is an acute, emergency intra-abdominal procedure performed without reconstruction of the vein. Typical codes: 06B60ZZ.
A middle-aged patient with chronic mesenteric venous thrombosis causing recurrent ischemic colitis is scheduled for an elective resection of chronically damaged venous segments identified on preoperative imaging; the planned open abdominal procedure includes excision of a portion of the inferior mesenteric vein to remove the thrombosed segment and restore venous drainage via collateral pathways. This is an elective inpatient excision performed without replacement of the vein. Typical codes: 06B60ZZ.
A patient who previously underwent endovascular therapy develops a persistent symptomatic venous stricture of the inferior mesenteric vein leading to recurrent lower GI bleeding and pain; during a percutaneous endoscopic-assisted procedure the surgeon excises the fibrotic segment of the vein to relieve obstruction and address the complication of prior intervention. Typical codes: 06B64ZZ, 06B64ZX
