ICD-10-PCS Code For Left Common Carotid Artery: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group X2AJ includes procedures performed to assist physiological blood flow or embolic protection devices in the left common carotid artery. These ICD-10-PCS codes are used for inpatient documentation when extracorporeal or device-based assistance is provided to support cerebral perfusion or prevent embolization during vascular procedures. Accurate coding within the ICD-10-PCS X2AJ group is essential for proper inpatient reimbursement, as it captures the assistance procedure performed and supports clinical documentation accuracy for payment and case mix.

Left Common Carotid Artery Assistance Procedure Overview

Procedures in the ICD-10 PCS X2AJ group involve taking over a portion of a physiological function for the cardiovascular system by extracorporeal means, specifically assisting blood flow or embolic protection associated with the left common carotid artery. These New Technology section procedures use extracorporeal or device-based assistance to protect cerebral circulation during vascular interventions. Accurate coding ensures inpatient records reflect the assistance operation and the left common carotid artery as the targeted body part, which affects case mix grouping and reimbursement.

When to Use

Use a code from this group when an extracorporeal or device-based assistance procedure is performed on the left common carotid artery to support cerebral perfusion or provide embolic protection. These codes apply when the operative report documents assistance as the root operation and identifies the left common carotid artery as the body part.

X2AJ34B	Left Common Carotid Artery Cerebral Embolic Filtration, Single Integrated Distal Filter, Percutaneous Approach, New Technology Group 11

Typical Clinical Scenarios

An elderly patient presents acutely with symptomatic high-grade stenosis of the left common carotid artery identified during evaluation for transient ischemic attacks; the vascular team plans an urgent endovascular carotid intervention and places a device-based cerebral embolic filtration via a percutaneous femoral approach to capture emboli during plaque manipulation, providing extracorporeal assistance to protect cerebral perfusion during the procedure. Typical codes: X2AJ34B
A middle-aged patient scheduled electively for left common carotid artery stent placement due to progressive symptomatic atherosclerotic disease undergoes planned percutaneous embolic protection using a single integrated distal filter to minimize peri-procedural cerebral embolization; this inpatient-coded assistance documents the use of a device-based, percutaneous embolic filtration specifically in the left common carotid artery. Typical codes: X2AJ34B
A patient with recent left carotid endarterectomy develops recurrent ipsilateral embolic phenomena and is taken to the operating suite for percutaneous salvage embolic protection and endovascular management of residual thrombus; a single integrated distal filter is deployed in the left common carotid artery to provide extracorporeal embolic filtration during the corrective intervention. Typical codes: X2AJ34B
