Zoster meningitis
ICD-10 B02.1 is a billable code used to indicate a diagnosis of zoster meningitis.
Zoster meningitis is a viral infection of the meninges caused by the varicella-zoster virus (VZV), which is the same virus responsible for chickenpox and shingles. This condition typically arises in individuals who have had a previous varicella infection, leading to the reactivation of the virus. The clinical presentation may include symptoms such as fever, headache, neck stiffness, and altered mental status. Patients may also exhibit signs of shingles, such as a painful rash, which can precede or accompany the meningitis. Diagnosis is primarily based on clinical evaluation, cerebrospinal fluid (CSF) analysis, and polymerase chain reaction (PCR) testing to detect VZV DNA. Complications can include neurological deficits, persistent pain, and in severe cases, death. Vaccination against varicella is crucial in preventing primary infection and subsequent reactivation, particularly in immunocompromised individuals who are at higher risk for developing zoster meningitis. Early recognition and treatment with antiviral medications can improve outcomes and reduce the risk of complications.
Detailed clinical notes on symptoms, lab results, and treatment plans.
Patients presenting with fever, headache, and rash.
Need for thorough history-taking, including vaccination status and previous varicella infection.
Neurological examination findings, imaging studies, and CSF analysis results.
Patients with neurological deficits or altered mental status.
Documentation of neurological assessments and any complications arising from the infection.
Used to confirm the diagnosis of zoster meningitis.
Document the reason for testing and the results.
Infectious disease specialists should ensure comprehensive documentation of the patient's history.
Common symptoms include fever, headache, neck stiffness, and altered mental status, often accompanied by a painful rash.
Diagnosis is made through clinical evaluation, CSF analysis, and PCR testing for varicella-zoster virus.
Vaccination against varicella significantly reduces the risk of primary infection and subsequent reactivation of the virus, which can lead to zoster meningitis.
