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 05H1 includes procedures performed to insert nonbiological appliances that monitor, assist, perform, or prevent a physiological function in the hemiazygos vein within the upper veins. These ICD-10-PCS codes are used for inpatient documentation when a device is placed into the hemiazygos vein to provide monitoring, therapy delivery, or physiologic support. Accurate coding within the ICD-10-PCS 05H1 group is essential for proper inpatient reimbursement, as it captures the procedure performed and supports clinical documentation accuracy and appropriate case mix assignment.

Typical Clinical Scenarios

An adult patient admitted to the hospital with sepsis from a central venous catheter requiring long-term targeted intravenous therapy and frequent hemodynamic monitoring; the clinical team elects to place a dedicated infusion/monitoring catheter into the hemiazygos vein to secure reliable central venous access and allow infusion of vasoactive agents while minimizing manipulation of existing peripheral lines. Typical codes: 05H133Z, 05H143Z
A neonate in the neonatal intensive care unit with complex congenital heart disease and difficult peripheral access who requires placement of a tunneled infusion device for ongoing parenteral nutrition and central venous pressure monitoring; the procedure is performed percutaneously under imaging guidance to access the hemiazygos vein for stable, long-term infusion support. Typical codes: 05H133Z, 05H13DZ
An inpatient with a malfunctioning intravascular infusion device previously placed in the hemiazygos vein presents with recurrent occlusions and extravasation; after assessment, the team elects to remove the failed device and insert a new intraluminal or infusion device into the hemiazygos vein during the same admission to restore reliable central access. Typical codes: 05H10DZ, 05H103Z
