Occlusion and stenosis of left anterior cerebral artery
ICD-10 I66.12 is a billable code used to indicate a diagnosis of occlusion and stenosis of left anterior cerebral artery.
I66.12 refers to the occlusion and stenosis of the left anterior cerebral artery (ACA), a critical vessel supplying blood to the medial portions of the frontal lobes and the superior medial parietal lobes. Clinically, patients may present with symptoms such as unilateral weakness, sensory loss, or cognitive impairments, depending on the extent of ischemia. The ACA is part of the anterior circulation of the brain, and occlusion can lead to significant neurological deficits. Disease progression may involve gradual stenosis due to atherosclerosis or acute occlusion from embolic events. Diagnostic considerations include imaging studies such as MRI or CT angiography to visualize the artery and assess blood flow. Doppler ultrasound may also be utilized to evaluate blood flow dynamics. Early diagnosis and intervention are crucial to prevent irreversible brain damage and optimize patient outcomes.

I66.12 covers conditions related to occlusion or stenosis of the left anterior cerebral artery, including ischemic strokes and transient ischemic attacks (TIAs) affecting this vascular territory.
I66.12 should be used when there is documented occlusion or stenosis specifically of the left anterior cerebral artery, differentiating it from other cerebral arteries or conditions.
Documentation should include clinical findings, imaging results confirming occlusion or stenosis, and any relevant treatment plans. Detailed notes on neurological assessments are also critical.
