Other acute necrotizing hemorrhagic encephalopathy
ICD-10 G04.39 is a billable code used to indicate a diagnosis of other acute necrotizing hemorrhagic encephalopathy.
Acute necrotizing hemorrhagic encephalopathy (ANHE) is a rare but severe neurological condition characterized by rapid onset of encephalopathy, often following a viral infection. It is marked by necrosis and hemorrhage in the brain, leading to significant neurological deficits. Patients typically present with altered mental status, seizures, and focal neurological signs. The condition can be associated with infections such as influenza, herpes simplex virus, and other viral pathogens. Diagnosis is primarily clinical, supported by neuroimaging findings that reveal bilateral thalamic lesions and other areas of hemorrhagic necrosis. The acute nature of the disease necessitates prompt medical intervention, often including antiviral therapy, supportive care, and management of complications. The prognosis can vary widely, with some patients experiencing full recovery while others may suffer long-term neurological impairment or even death. Given its acute presentation and potential for rapid deterioration, accurate coding is crucial for appropriate treatment and resource allocation.
Comprehensive neurological examination findings, imaging results, and treatment plans.
Patients presenting with acute neurological symptoms post-viral infection.
Ensure clarity in documenting the acute nature and specific findings of necrotizing hemorrhagic encephalopathy.
Detailed history of viral infections, laboratory results, and response to antiviral therapy.
Patients with recent viral illnesses developing neurological symptoms.
Document the infectious etiology and its correlation with neurological manifestations.
Used to evaluate for hemorrhagic changes in suspected cases of G04.39.
Document indication for CT scan and findings.
Neurology specialists should ensure imaging correlates with clinical findings.
Common causes include viral infections such as influenza, herpes simplex virus, and other viral pathogens. It often follows a recent viral illness.
