Occlusion and stenosis of right anterior cerebral artery
ICD-10 I66.11 is a billable code used to indicate a diagnosis of occlusion and stenosis of right anterior cerebral artery.
I66.11 refers to the occlusion and stenosis of the right anterior cerebral artery, a critical condition affecting cerebral blood flow. The anterior cerebral artery (ACA) is responsible 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 or paralysis of the contralateral leg, sensory loss, and cognitive deficits, depending on the extent of ischemia. Disease progression can lead to significant neurological impairment, including stroke, if not managed promptly. Diagnostic considerations include imaging studies such as MRI or CT angiography to assess the degree of occlusion or stenosis and to rule out other cerebrovascular diseases. Early detection and intervention are crucial to prevent irreversible brain damage and improve patient outcomes.

I66.11 encompasses occlusion and stenosis of the right anterior cerebral artery, which may result from atherosclerosis, embolism, or other vascular diseases leading to reduced blood flow and potential ischemic events.
I66.11 should be used when there is confirmed occlusion or stenosis specifically of the right anterior cerebral artery, as opposed to other arteries or conditions that may present similarly.
Documentation should include clinical findings, imaging results confirming occlusion or stenosis, and any relevant history of cerebrovascular disease or risk factors.
