Zoster encephalitis
ICD-10 B02.0 is a billable code used to indicate a diagnosis of zoster encephalitis.
Zoster encephalitis is a rare but serious complication of varicella-zoster virus (VZV) infection, which is the virus responsible for both chickenpox and shingles. This condition occurs when the virus reactivates in the nervous system, leading to inflammation of the brain. Patients may present with neurological symptoms such as confusion, seizures, and altered mental status, often accompanied by a history of shingles. Diagnosis is typically confirmed through clinical evaluation, imaging studies like MRI, and laboratory tests that may include PCR testing of cerebrospinal fluid (CSF) for VZV DNA. Treatment usually involves antiviral medications, such as acyclovir, and supportive care. Early recognition and management are crucial to minimize potential long-term neurological deficits. The incidence of zoster encephalitis is higher in immunocompromised individuals, making vaccination against VZV an important preventive measure, especially in at-risk populations.
