Cerebral ischaemic stroke due to unspecified occlusion or stenosis of extracranial large artery

Description

This is a sudden loss of brain function due to a lack of adequate blood flow of the large extracranial arteries.

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.
