Varicella encephalitis and encephalomyelitis
ICD-10 B01.11 is a billable code used to indicate a diagnosis of varicella encephalitis and encephalomyelitis.
Varicella encephalitis and encephalomyelitis are serious complications of varicella (chickenpox) infection, primarily caused by the varicella-zoster virus (VZV). These conditions can occur in both immunocompetent and immunocompromised individuals, although they are more common in the latter. Encephalitis refers to inflammation of the brain, while encephalomyelitis involves inflammation of both the brain and spinal cord. Symptoms may include fever, headache, altered mental status, seizures, and focal neurological deficits. Diagnosis is typically confirmed through clinical evaluation, imaging studies such as MRI, and laboratory tests including PCR for VZV in cerebrospinal fluid. Prompt recognition and treatment are crucial, as these conditions can lead to significant morbidity and mortality. Management often involves antiviral therapy, supportive care, and monitoring for potential complications such as seizures or neurological deficits.
Detailed neurological examination findings, imaging results, and laboratory tests.
Patients presenting with seizures, altered mental status, or focal neurological deficits following varicella infection.
Ensure clear documentation of the timeline of varicella infection and neurological symptoms.
History of varicella infection, immunization status, and any co-morbid conditions.
Immunocompromised patients with varicella presenting with neurological symptoms.
Document any antiviral treatments and their effects on the patient's condition.
Used when confirming varicella infection in a patient with encephalitis.
Document the reason for testing and any clinical symptoms.
Infectious disease specialists should ensure comprehensive documentation of the patient's history.
Common symptoms include fever, headache, confusion, seizures, and focal neurological deficits. These symptoms may develop after a recent varicella infection.
