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

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group 06R5 includes procedures performed to replace biological or synthetic material that takes the place and/or function of the superior mesenteric vein in the lower veins. These ICD-10-PCS codes are used for inpatient documentation when a patient requires replacement of the superior mesenteric vein due to injury, thrombosis, disease, or other pathology necessitating venous reconstruction. Accurate coding within the ICD-10-PCS 06R5 group is essential for proper inpatient reimbursement, as it captures the specific replacement procedure performed and supports clinical documentation accuracy.

Superior Mesenteric Vein Replacement Procedure Overview

Procedures in this group involve replacement of all or part of the superior mesenteric vein using biological or synthetic material and target the lower veins body system. These operations physically take the place and/or function of the superior mesenteric vein to restore venous continuity and flow. Accurate ICD-10-PCS coding is important for inpatient reimbursement because it documents the complexity and resource use associated with vascular replacement procedures.

Use a code from this group when the superior mesenteric vein is surgically replaced during an inpatient encounter to restore venous flow due to trauma, thrombosis, tumor involvement, or other pathology. Do not use these codes for simple repair, bypass without replacement, or nonoperative management.

Typical Clinical Scenarios

An adult patient presents emergently with acute mesenteric venous thrombosis causing bowel ischemia and venous congestion after failed anticoagulation; during exploratory laparotomy the surgical team performs resection of irreversibly damaged venous segments and replaces the occluded superior mesenteric vein with a synthetic graft to restore mesenteric venous outflow and permit bowel salvage. Typical codes: 06R50JZ
An elective case in a patient with chronic portal hypertension and progressive mesenteric venous stenosis from prior inflammation who has recurrent postprandial pain and worsening mesenteric edema; planned inpatient surgery is undertaken to excise the diseased segment and reconstruct the superior mesenteric vein using the patient’s own vein conduit (autologous tissue substitute) to reestablish durable venous drainage. Typical codes: 06R507Z
A patient with prior venous reconstruction for trauma returns with graft failure and recurrent venous insufficiency; during a scheduled inpatient revision the surgeon removes the failed graft and replaces the superior mesenteric vein with a nonautologous biological conduit (nonautologous tissue substitute) to restore venous continuity and treat the complication of graft breakdown. Typical codes: 06R50KZ
