8B11.0

ICD-11 MMS 2026-01

Cerebral ischaemic stroke due to extracranial large artery atherosclerosis

Description

Cerebral ischaemic stroke is characterized by the sudden onset of focal neurological deficits within a vascular territory stemming from underlying cerebrovascular pathology, namely atherosclerosis. Large artery atherosclerosis of the head and neck is responsible for approximately 15% of all ischemic strokes.

Coding note

If an additional code is used for anatomy, the artery affected by the stroke should be selected.

Coding note from above levels

When the cause of ischaemic stroke is known, code to the cause. When the cause of ischaemic stroke is not known, code to 8B11.5-. When the cause of stroke is not known, code to 8B20 Stroke not known if ischaemic or haemorrhagic.
