ICD-10-PCS Code For Hemiazygos Vein: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group 05R1 includes procedures performed to replace venous structures in the hemiazygos vein. These ICD-10-PCS codes are used for inpatient documentation when a diseased, damaged, or nonfunctional segment of the hemiazygos vein is removed and substituted with biological or synthetic material. Accurate coding within the ICD-10-PCS 05R1 group is essential for proper inpatient reimbursement, as it captures the replacement procedure performed and supports clinical documentation accuracy.

Hemiazygos Vein Replacement Procedure Overview

This code group includes procedures that replace all or part of the hemiazygos vein with biological or synthetic material and target the upper venous system. These inpatient operations remove a diseased or damaged segment of the hemiazygos vein and implant a graft or conduit to restore venous continuity. Accurate ICD-10-PCS coding ensures the documented replacement procedure is captured for correct clinical records and inpatient reimbursement.

When to Use

Use a code from this group when the hemiazygos vein is surgically removed and replaced due to disease, injury, thrombosis, or other pathology impairing its function. Select the specific ICD-10-PCS code that reflects the replacement operation and the material used for the graft or conduit.

Typical Clinical Scenarios

A middle-aged patient presents emergently with acute chest wall trauma after a motor vehicle collision causing a transected hemiazygos vein with ongoing intrathoracic hemorrhage and hemodynamic instability; surgical exploration in the operating room requires resection of the damaged venous segment and immediate implantation of a synthetic conduit to restore venous continuity and control bleeding. Typical codes: 05R10JZ.
An elderly patient with chronic venous insufficiency and progressive thrombosis involving a nonhealing posterior thoracic venous segment of the hemiazygos vein is scheduled electively for removal of the diseased segment and replacement with the patient’s own vein graft harvested from the lower extremity to re-establish flow and prevent recurrent embolic events. Typical codes: 05R107Z.
A patient with prior endovascular stent placement in the hemiazygos vein develops stent infection and persistent sepsis requiring inpatient removal of the infected segment and substitution with a cryopreserved (nonautologous) venous graft via a minimally invasive endoscopic approach to eradicate infection and restore venous drainage. Typical codes: 05R14KZ.
