ICD-10-PCS Code For Inferior Mesenteric Vein: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group 06U6 includes procedures performed to supplement venous structures in the inferior mesenteric vein. These ICD-10-PCS codes are used for inpatient documentation when biological or synthetic material is placed to reinforce or augment the inferior mesenteric vein. Accurate coding within the ICD-10-PCS 06U6 group is essential for proper inpatient reimbursement, as it captures the specific supplement procedure performed and supports clinical documentation accuracy.

Inferior Mesenteric Vein Supplement Procedure Overview

Procedures in this group involve placing biological or synthetic material to reinforce or augment the function of the inferior mesenteric vein within the lower venous system. These operations target the lower veins and specifically the inferior mesenteric vein to support venous structure or flow. Accurate ICD-10-PCS coding is important for documenting the supplement procedure performed and for appropriate inpatient reimbursement.

Typical Clinical Scenarios

An adult patient presents emergently with acute mesenteric venous insufficiency after blunt abdominal trauma causing focal disruption and extrinsic compression of the inferior mesenteric vein. Intraoperative assessment during an open laparotomy reveals segmental venous wall defect requiring reinforcement with harvested autologous tissue to restore venous integrity and prevent thrombosis. A supplement procedure using autologous tissue via an open approach is performed. Typical codes: 06U607Z
An older patient with chronic venous insufficiency of the lower mesenteric venous drainage and recurrent symptomatic venous outflow obstruction undergoes a planned percutaneous endoscopic intervention. The procedure places a synthetic material to augment the inferior mesenteric vein lumen and improve flow after conservative therapies and imaging-guided evaluation. This elective supplement is performed in a controlled inpatient setting via a percutaneous endoscopic approach. Typical codes: 06U64JZ
A middle-aged patient returns for revision after prior percutaneous augmentation of the inferior mesenteric vein with a nonautologous tissue substitute that developed migration and partial failure, resulting in recurrent symptoms and imaging evidence of inadequate support. A percutaneous approach is used to remove or revise the prior material and re-supplement the vein with a compatible nonautologous tissue substitute to restore venous function. Typical codes: 06U63KZ, 06U64KZ
