Occlusion and stenosis of unspecified anterior cerebral artery
ICD-10 I66.19 is a billable code used to indicate a diagnosis of occlusion and stenosis of unspecified anterior cerebral artery.
I66.19 refers to occlusion and stenosis of the unspecified anterior cerebral artery, a condition that can lead to significant neurological deficits due to reduced blood flow to the brain. The anterior cerebral artery (ACA) supplies blood to the medial portions of the frontal lobes and the superior medial parietal lobes. Clinical presentation may include symptoms such as weakness or paralysis of the lower limbs, changes in behavior, and cognitive impairments. Disease progression can vary; some patients may experience transient ischemic attacks (TIAs) or full-blown strokes, depending on the severity of the occlusion or stenosis. Diagnostic considerations include imaging studies such as MRI or CT angiography to visualize blood flow and identify blockages. Early detection and intervention are crucial to prevent irreversible brain damage and improve patient outcomes.

I66.19 encompasses occlusion and stenosis of the anterior cerebral artery that is not specified as right or left. It may include conditions such as atherosclerosis, embolism, or thrombosis affecting blood flow.
I66.19 should be used when the specific side of the anterior cerebral artery is not documented. If the occlusion is specified as right or left, the corresponding codes (I66.01 or I66.02) should be used.
Documentation should include clinical findings, imaging results that confirm occlusion or stenosis, and any relevant patient history that supports the diagnosis.
