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

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group 05R0 includes procedures performed to replace biological or synthetic material that takes the place and/or function of the azygos vein in the upper veins. These ICD-10-PCS codes are used for inpatient documentation when a portion or all of the azygos vein is replaced with biological or synthetic material due to disease, injury, or other clinical indications. Accurate coding within the ICD-10-PCS 05R0 group is essential for proper inpatient reimbursement, as it captures the procedure performed and determines appropriate case mix and payment.

Azygos Vein Replacement Procedure Overview

Procedures in this group involve replacement of the azygos vein and target the upper veins of the thorax. These operations place biological or synthetic material that physically takes the place and/or function of all or a portion of the azygos vein. Accurate coding of these procedures is critical for inpatient reimbursement because it captures the specific replacement operation and supports appropriate case mix assignment.

Typical Clinical Scenarios

An adult patient presents emergently after blunt chest trauma with massive thoracic hemorrhage and disruption of the azygos vein identified on CT and during operative exploration. Because primary repair is not feasible due to segmental loss, the surgical team performs open replacement of the damaged segment of the azygos vein using autologous tissue (vein graft harvested from the patient) to restore venous continuity and control bleeding. The procedure is performed in the operating room under general anesthesia as an urgent life‑saving intervention. Typical codes: 05R007Z
A middle‑aged patient with chronic symptomatic compression of the upper thoracic venous system from prior mediastinal radiation and stenosis of the azygos vein is scheduled for elective reconstruction. The planned operation replaces the narrowed segment of the azygos vein with a synthetic vascular graft via an open thoracic approach to reestablish adequate venous drainage and relieve edema and venous hypertension symptoms. This is an inpatient, planned procedure with preoperative imaging and multidisciplinary planning. Typical codes: 05R00JZ
A patient with a prior endovascular repair of an azygos vein injury develops graft infection and graft breakdown requiring removal and definitive replacement. The team performs a percutaneous endoscopic removal of the failed conduit and replacement of the affected azygos vein segment with nonautologous tissue substitute (cryopreserved allograft) to manage infection risk and restore venous flow. This inpatient procedure addresses a complication of a previous vascular intervention. Typical codes: 05R04KZ
