Occlusion and stenosis of bilateral anterior cerebral arteries
ICD-10 I66.13 is a billable code used to indicate a diagnosis of occlusion and stenosis of bilateral anterior cerebral arteries.
I66.13 refers to occlusion and stenosis of bilateral anterior cerebral arteries, a condition characterized by the narrowing or blockage of the arteries that supply blood to the anterior portion of the brain. This condition can lead to significant neurological deficits, including cognitive impairment, motor dysfunction, and increased risk of stroke. The anterior cerebral arteries are crucial for supplying blood to the medial portions of the frontal lobes and the superior medial parietal lobes. Clinical presentation may include symptoms such as weakness, sensory loss, and changes in behavior or personality. Disease progression can vary, with some patients experiencing acute events while others may have chronic symptoms due to gradual stenosis. Diagnostic considerations include imaging studies such as MRI or CT angiography to assess blood flow and identify occlusions. Early detection and management are critical to prevent irreversible brain damage and improve patient outcomes.

I66.13 covers conditions related to occlusion and stenosis of both anterior cerebral arteries, which may include atherosclerosis, embolism, or thrombosis leading to reduced blood flow and potential ischemic events.
I66.13 should be used when there is documented occlusion or stenosis affecting both anterior cerebral arteries, differentiating it from unilateral codes which only pertain to one artery.
Documentation must include clinical findings, imaging results showing bilateral occlusion or stenosis, and any relevant history of cardiovascular disease or stroke risk factors.
