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 03R2 includes procedures performed to replace segments of the innominate artery in the upper arteries. These ICD-10-PCS codes are used for inpatient documentation when a patient undergoes surgical replacement of the innominate artery with biological or synthetic material for conditions such as aneurysm, occlusion, or trauma. Accurate coding within the ICD-10-PCS 03R2 group is essential for proper inpatient reimbursement, as it captures the procedure performed and determines appropriate case mix and payment.

Innominate Artery Replacement Procedure Overview

Procedures in this group involve replacement of the innominate artery within the upper arteries vascular system and consist of removing and substituting all or part of the artery with biological or synthetic material. These operations address arterial disease, trauma, aneurysm, or occlusion affecting the innominate artery and restore blood flow to the head and right upper extremity. Accurate coding of these replacement procedures is important for inpatient reimbursement because it captures the extent of surgical intervention and supports appropriate case mix assignment.

When to Use

Use a code from this group when a surgical operation removes part or all of the innominate artery and implants material to restore arterial continuity or function. Typical clinical circumstances include treatment of aneurysm, penetrating or blunt trauma, occlusive disease, or graft failure requiring complete or partial arterial replacement.

Typical Clinical Scenarios

An elderly patient with a rapidly expanding innominate artery aneurysm detected on surveillance imaging presents for elective inpatient repair due to risk of rupture and compressive symptoms to the trachea and right upper extremity ischemia; surgical removal of the diseased arterial segment and implantation of a conduit restores flow and prevents catastrophic hemorrhage. Typical codes: 03R20JZ, 03R207Z
A middle-aged patient involved in high-speed motor vehicle trauma sustains a transection of the innominate artery with active hemorrhage and neurologic compromise to the right arm; the patient is taken emergently to the operating room for excision of the injured segment and immediate replacement with a synthetic graft to re-establish cerebral and upper extremity perfusion. Typical codes: 03R20JZ
A patient with prior innominate artery bypass presents with graft degeneration and infection necessitating removal of the failed conduit and reconstruction using the patient’s own vein graft or a nonautologous biologic conduit during an inpatient admission for staged revascularization and infection control. Typical codes: 03R247Z, 03R24KZ
