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 03B2 includes procedures performed to excise portions of the innominate artery in the upper arteries. These ICD-10-PCS codes are used for inpatient documentation when a segment of the innominate artery is surgically removed due to disease, injury, or other pathology requiring excision. Accurate coding within the ICD-10-PCS 03B2 group is essential for proper inpatient reimbursement, as it captures the procedure performed and supports clinical documentation accuracy.

These operations target the upper arteries and are classified under the Medical and Surgical section. Accurate selection of the correct International Classification of Diseases, Tenth Revision, Procedure Coding System code supports proper inpatient documentation and reimbursement by reflecting the specific body part and operation performed. Precise coding also aids clinical record integrity and case mix assignment.

When to Use

Use a code from this group when a surgeon removes a portion of the innominate artery and does not replace it during the same encounter. These codes apply when the primary intraoperative action is excision of arterial tissue in the innominate artery for reasons such as ischemia, aneurysm, dissection, trauma, or localized arterial disease.

Typical Clinical Scenarios

An elderly patient presents to the emergency department with sudden onset of right arm ischemia and loss of distal pulses after blunt chest trauma. Imaging reveals a focal transection and nonviable segment of the innominate artery requiring surgical removal of the damaged arterial portion without immediate reconstruction. An open excision of the injured segment is performed to control hemorrhage and remove devitalized arterial tissue. Typical codes: 03B20ZZ
A middle-aged patient with an expanding saccular aneurysm of the innominate artery identified on routine surveillance is scheduled for operative management. Because the surgeon plans a minimally invasive endovascular-guided excision of the aneurysmal segment via a percutaneous approach without placing a replacement graft during the same admission, the procedure documents removal of the diseased arterial segment. Typical codes: 03B23ZZ
A postoperative patient returning for management of persistent infection at a prior arterial repair site has a localized infected pseudoaneurysm of the innominate artery. To remove the source of infection, the operative plan is percutaneous endoscopic excision of the affected arterial segment without reconstructive replacement during this encounter, with plans for staged reconstruction after infection control. Typical codes: 03B24ZZ
