Occlusion and stenosis of cerebral arteries, not resulting in cerebral infarction
Chapter 9:Diseases of the circulatory system
ICD-10 I66 is a used to indicate a diagnosis of occlusion and stenosis of cerebral arteries, not resulting in cerebral infarction.
The ICD-10 code I66 encompasses occlusion and stenosis of cerebral arteries that do not lead to cerebral infarction. This category includes various conditions where blood flow to the brain is compromised due to narrowing or blockage of the arteries, but without resulting in a stroke. Common conditions under this category may include transient ischemic attacks (TIAs) and other vascular issues that affect cerebral circulation. Clinically, it is significant as it helps in identifying patients at risk for future strokes and allows for timely intervention to prevent further complications. The management of these conditions often involves lifestyle modifications, medications, and sometimes surgical interventions to restore adequate blood flow to the brain.

I66 includes occlusion and stenosis of cerebral arteries, such as carotid artery stenosis and vertebral artery occlusion, that do not result in cerebral infarction.
I66 codes should be used when a patient presents with symptoms indicative of cerebral artery occlusion or stenosis, but without evidence of a cerebral infarction, as confirmed by imaging studies.
Documentation must include clinical findings, imaging results, and any relevant patient history that supports the diagnosis of occlusion or stenosis without cerebral infarction.
