ICD-10-PCS Code For Innominate Artery: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group 03S2 includes procedures performed to reposition structures in the innominate artery. These ICD-10-PCS codes are used for inpatient documentation when a surgical repositioning of all or part of the innominate artery is performed to correct location or alignment. Accurate coding within the ICD-10-PCS 03S2 group is essential for proper inpatient reimbursement, as it captures the procedure performed and supports clinical documentation accuracy.

Innominate Artery Reposition Procedure Overview

Procedures in this group involve repositioning all or a portion of the innominate artery within the upper arterial system to restore or improve anatomical alignment and blood flow. These operations target the upper arteries and typically require inpatient surgical care due to vascular complexity and monitoring needs. Accurate coding of these reposition procedures is important for reflecting the clinical work performed and for appropriate inpatient reimbursement and case mix assignment.

When to Use

Use a code from this group when a surgical procedure is performed to reposition the innominate artery to correct malposition or improve vascular alignment. These codes apply when the operative intent is to move the artery rather than to resect, bypass, or repair it.

Typical Clinical Scenarios

An elderly patient is admitted urgently with acute symptomatic compression of the innominate artery secondary to aortic arch aneurysmal dilation causing cerebral hypoperfusion and brachial ischemia. Imaging shows malalignment of the proximal innominate artery trajectory that can be corrected by surgically repositioning the vessel via an open sternotomy to relieve kinking and restore antegrade flow. An open repositioning is performed because endovascular access is unsuitable given the anatomy and need for direct vascular mobilization and fixation. Typical codes: 03S20ZZ
A middle-aged patient with chronic symptomatic subclavian steal–type symptoms and pulsatile mass at the base of the neck is scheduled for inpatient correction after outpatient evaluation. Preoperative studies identify a congenital malposition of the proximal innominate artery producing recurrent ischemic symptoms; a planned percutaneous endovascular realignment is attempted using image guidance and endoscopic assistance to reposition the vessel and secure it in a more anatomic position. The minimally invasive percutaneous endoscopic approach is selected to reduce surgical morbidity while achieving vessel repositioning. Typical codes: 03S24ZZ
A patient with prior endovascular stenting of the innominate artery presents with new onset upper extremity claudication and imaging demonstrates stent-induced migration causing vessel malposition and kinking. Because the issue represents a procedural complication leading to malalignment, a percutaneous non-open maneuver is performed to reposition the native innominate artery and correct flow dynamics without open reoperation. A percutaneous approach is chosen to address the complication while avoiding repeat open chest surgery. Typical codes: 03S23ZZ
