ICD Code I67.81

ICD code I67.81 is acute cerebrovascular insufficiency, which refers to a sudden reduction of blood flow to the brain that can cause neurological symptoms but does not meet the criteria for a stroke.

1. Sudden onset of neurological deficits such as weakness, numbness, or difficulty speaking

2. Transient episodes of confusion, dizziness, or loss of consciousness

3. Evidence of reduced cerebral blood flow without infarction on imaging studies

4. Symptoms not attributable to other causes such as hypoglycemia, seizure, or migraine

5. Acute presentation with rapid resolution of symptoms, typically within 24 hours

6. No evidence of acute stroke or hemorrhage on neuroimaging

7. Associated risk factors such as hypertension, atherosclerosis, or cardiac disease
