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

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group X2AL includes procedures performed to assist a portion of physiological function of the internal carotid artery in the left side of the head and neck. These ICD-10-PCS codes are used for inpatient documentation when extracorporeal assistance devices are employed to support the left internal carotid artery during cerebral protection or endovascular interventions. Accurate coding within the ICD-10-PCS X2AL group is essential for proper inpatient reimbursement, as it captures the use of assistance technologies and supports clinical documentation accuracy and appropriate case mix and payment.

Left Internal Carotid Artery Assistance Procedure Overview

Procedures in this group involve providing extracorporeal assistance to the left internal carotid artery within the cardiovascular system by taking over a portion of the artery's physiological function. These interventions use an extracorporeal device or technology to assist cerebral protection during endovascular procedures. Accurate ICD-10-PCS coding ensures inpatient records reflect the use of assistance technologies and supports appropriate case mix assignment and payment.

When to Use

Use codes from this group when an extracorporeal assistance device is used to support or protect the left internal carotid artery during an inpatient endovascular procedure. These codes apply when the operation performed is assistance rather than removal, repair, or bypass of the artery.

ICD-10-PCS Code	Description
X2AL34B	Left Internal Carotid Artery Cerebral Embolic Filtration, Single Integrated Distal Filter, Percutaneous Approach, New Technology Group 11

Typical Clinical Scenarios

An elderly patient with symptomatic high-grade carotid artery stenosis distal to the common carotid presents for an urgent inpatient carotid artery stenting because of crescendo transient ischemic attacks despite medical therapy; during the endovascular procedure the team deploys a distal embolic protection device to capture dislodged plaque and protect the ipsilateral cerebral circulation. A percutaneous, single integrated distal filter is used to provide extracorporeal assistance for cerebral embolic filtration of the left internal carotid artery. Typical codes: X2AL34B
A middle-aged patient scheduled electively for left internal carotid artery angioplasty and stent placement for symptomatic restenosis after prior carotid endarterectomy is admitted for the planned endovascular intervention; to minimize risk of cerebral embolization during stent deployment, the interventionalist uses a percutaneous integrated distal filter device to support cerebral protection. The procedure represents assisted extracorporeal embolic filtration of the left internal carotid artery in a controlled, elective inpatient setting. Typical codes: X2AL34B
A patient admitted emergently with acute ischemic stroke undergoing urgent left internal carotid artery thrombectomy experiences concern for distal embolization during retrieval; the interventional team adds a percutaneous single integrated distal filter to capture emboli and protect cerebral circulation during adjunctive maneuvers. This represents use of an extracorporeal assistance device to take over part of the artery’s physiologic function for embolic protection in an acute complication scenario. Typical codes: X2AL34B
