Cerebral infarction due to thrombosis of unspecified anterior cerebral artery
ICD-10 I63.329 is a billable code used to indicate a diagnosis of cerebral infarction due to thrombosis of unspecified anterior cerebral artery.
Cerebral infarction due to thrombosis of an unspecified anterior cerebral artery is a type of ischemic stroke that occurs when a blood clot obstructs blood flow to a part of the brain supplied by the anterior cerebral artery (ACA). The ACA is responsible for supplying blood to the medial portions of the frontal lobes and the superior medial parietal lobes. Clinical presentation may include sudden onset of weakness or paralysis, particularly affecting the lower limbs, changes in speech, and cognitive deficits. The progression of the disease can vary; some patients may experience rapid deterioration, while others may have a more gradual onset of symptoms. Diagnostic considerations include neuroimaging studies such as CT or MRI to confirm the presence of an infarct and to rule out hemorrhagic stroke. Additionally, risk factors such as hypertension, diabetes, hyperlipidemia, and smoking should be assessed to guide management and prevention strategies.

I63.329 covers cerebral infarction due to thrombosis affecting the anterior cerebral artery, specifically when the exact artery involved is not specified. It includes ischemic strokes resulting from thrombosis, which may present with varying neurological deficits.
I63.329 should be used when the specific anterior cerebral artery involved is not documented. If the documentation specifies the artery, a more specific code should be selected, such as I63.311 for the right anterior cerebral artery.
Documentation should include clinical findings, imaging results confirming the cerebral infarction, and a clear treatment plan. Notes should detail the onset of symptoms, risk factors, and any interventions performed.
