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 03U2 includes procedures performed to supplement vessels with biological or synthetic material in the innominate artery. These ICD-10-PCS codes are used for inpatient documentation when reinforcement or augmentation of the innominate artery is performed to support or restore arterial function. Accurate coding within the ICD-10-PCS 03U2 group is essential for proper inpatient reimbursement, as it captures the supplemental procedure performed and determines appropriate case mix and payment.

Innominate Artery Supplement Procedure Overview

Procedures in this group involve placing biological or synthetic material to reinforce or augment the innominate artery within the upper arterial system. These operations target the upper arteries and specifically the innominate artery to support vessel function or integrity. Accurate ICD-10-PCS coding ensures the inpatient record reflects the supplemental reinforcement performed and supports correct case mix assignment and reimbursement.

Typical Clinical Scenarios

An elderly patient presents urgently with a symptomatic saccular aneurysm of the innominate artery discovered after transient ischemic symptoms and imaging showing focal vessel wall weakness without sac rupture. Given the focal arterial wall defect and need to reinforce the vessel to prevent expansion or embolization, the surgical team performs an open placement of a biologic patch harvested from the patient to augment the innominate artery wall. This inpatient operation is coded to reflect an open supplement of the innominate artery using autologous tissue. Typical codes: 03U207Z
A middle-aged patient with advanced atherosclerotic disease develops progressive stenosis of the innominate artery causing vertebrobasilar insufficiency and upper extremity claudication. After endovascular evaluation, the team elects a percutaneous placement of a synthetic reinforcing graft to augment the arterial lumen and improve flow without converting to open surgery. The inpatient record documents percutaneous supplementation of the innominate artery with a synthetic substitute. Typical codes: 03U23JZ
A patient who previously underwent endovascular repair of the innominate artery returns with graft edge degeneration and recurrent pseudoaneurysm at the prior repair site, presenting with chest pressure and concern for impending rupture. During an urgent percutaneous endoscopic procedure, surgeons place a nonautologous biologic patch to reinforce the compromised segment and manage the complication. The operation is coded as percutaneous endoscopic supplementation of the innominate artery with a nonautologous tissue substitute. Typical codes: 03U24KZ
