Occlusion and stenosis of precerebral arteries, not resulting in cerebral infarction
Chapter 9:Diseases of the circulatory system
ICD-10 I65 is a used to indicate a diagnosis of occlusion and stenosis of precerebral arteries, not resulting in cerebral infarction.
I65 refers to the occlusion and stenosis of precerebral arteries, which are the arteries supplying blood to the brain before it enters the cranial cavity. This condition can lead to reduced blood flow to the brain, potentially resulting in transient ischemic attacks (TIAs) or other neurological symptoms, but does not result in cerebral infarction. Clinically, patients may present with symptoms such as dizziness, visual disturbances, or transient weakness. The anatomy involved includes the carotid arteries (internal and external) and vertebral arteries, which are critical for cerebral perfusion. Disease progression can vary; some patients may remain asymptomatic while others may experience worsening symptoms or complications. Diagnostic considerations include imaging studies such as Doppler ultrasound, CT angiography, or MR angiography to assess blood flow and identify the location and severity of the occlusion or stenosis. Early detection and management are crucial to prevent further complications.

I65 covers occlusion and stenosis of precerebral arteries, including conditions such as carotid artery stenosis and vertebral artery stenosis, which may be identified through imaging studies and clinical evaluation.
I65 should be used when there is documented occlusion or stenosis of precerebral arteries without evidence of cerebral infarction. It is important to differentiate it from codes indicating cerebral infarction (I63) or transient ischemic attacks (G45).
Documentation must include imaging results showing the occlusion or stenosis, clinical symptoms experienced by the patient, and any relevant history of cerebrovascular disease. Detailed notes on the patient's neurological examination are also essential.
