Hypertensive encephalopathy
ICD-10 I67.4 is a billable code used to indicate a diagnosis of hypertensive encephalopathy.
Hypertensive encephalopathy is a severe complication of hypertension characterized by acute neurological dysfunction due to elevated blood pressure. Clinically, patients may present with symptoms such as headache, confusion, visual disturbances, seizures, and altered mental status. The condition arises from the effects of prolonged high blood pressure on the cerebral vasculature, leading to blood-brain barrier disruption, cerebral edema, and potential ischemic damage. The anatomy involved primarily includes the brain's vascular structures, particularly the small penetrating arteries that supply deep brain structures. Disease progression can be rapid, with acute episodes potentially leading to permanent neurological deficits if not promptly treated. Diagnostic considerations include a thorough clinical evaluation, imaging studies such as CT or MRI to rule out other causes of encephalopathy, and monitoring of blood pressure levels. The diagnosis is often confirmed when neurological symptoms correlate with severely elevated blood pressure readings, typically above 180/120 mmHg.

I67.4 specifically covers hypertensive encephalopathy, which is characterized by acute neurological symptoms resulting from severely elevated blood pressure. It is crucial to differentiate it from other types of encephalopathy, such as metabolic or toxic encephalopathy.
I67.4 should be used when a patient presents with neurological symptoms directly attributable to acute hypertension. It is important to use this code when there is clear evidence of elevated blood pressure correlating with the onset of neurological symptoms, distinguishing it from other encephalopathies.
Documentation should include a detailed account of the patient's blood pressure readings, neurological examination findings, imaging results, and any treatments administered. Clear correlation between hypertension and neurological symptoms is essential for supporting the use of I67.4.
