Occlusion and stenosis of unspecified precerebral artery
ICD-10 I65.9 is a billable code used to indicate a diagnosis of occlusion and stenosis of unspecified precerebral artery.
I65.9 refers to occlusion and stenosis of an unspecified precerebral artery, which is a condition characterized by the narrowing or blockage of arteries that supply blood to the brain. This condition can lead to reduced blood flow, increasing the risk of ischemic strokes and transient ischemic attacks (TIAs). The precerebral arteries include the internal carotid arteries and their branches, which are crucial for cerebral perfusion. Clinical presentation may vary, with some patients experiencing no symptoms, while others may present with neurological deficits, dizziness, or transient loss of consciousness. Disease progression can be insidious, often exacerbated by risk factors such as hypertension, diabetes, hyperlipidemia, and smoking. Diagnosis typically involves 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 identification and management are essential to prevent serious complications, including stroke.

I65.9 covers occlusion and stenosis of unspecified precerebral arteries, which may include conditions leading to reduced cerebral blood flow, such as atherosclerosis or embolism affecting the internal carotid arteries or their branches.
I65.9 should be used when the specific artery affected is not documented or when the occlusion or stenosis is generalized without specification. If a specific artery is identified, related codes like I65.0 or I65.1 should be used.
Documentation should include clinical findings, imaging results that indicate occlusion or stenosis, and any relevant patient history that supports the diagnosis, including risk factors and symptoms.
