Herpesviral meningitis
Chapter 1:Certain infectious and parasitic diseases
ICD-10 B00.1 is a billable code used to indicate a diagnosis of herpesviral meningitis.
Herpesviral meningitis is an inflammation of the protective membranes covering the brain and spinal cord, primarily caused by the herpes simplex virus (HSV). This condition can occur in both adults and children, with HSV type 1 being the most common causative agent. Patients typically present with symptoms such as fever, headache, neck stiffness, and altered mental status. Diagnosis is often confirmed through lumbar puncture, revealing pleocytosis with a predominance of lymphocytes and elevated protein levels in the cerebrospinal fluid (CSF). While herpesviral meningitis is generally less severe than bacterial meningitis, it can lead to complications such as seizures, neurological deficits, and in rare cases, death. Treatment usually involves antiviral medications, such as acyclovir, which can significantly reduce morbidity if administered early. Vaccination against HSV is not currently available, making prevention through safe practices essential. Understanding the clinical presentation and management of herpesviral meningitis is crucial for timely diagnosis and treatment.
Detailed neurological examination findings, CSF analysis results, and treatment plans.
Patients presenting with fever, headache, and altered mental status requiring lumbar puncture.
Ensure clear documentation of neurological deficits and response to antiviral therapy.
History of exposure, laboratory confirmation of HSV, and treatment response.
Patients with recurrent herpes infections presenting with neurological symptoms.
Document any co-infections and the rationale for antiviral therapy.
Used to obtain CSF for analysis in suspected meningitis cases.
Document indication for lumbar puncture and CSF findings.
Neurology specialists should ensure thorough documentation of neurological assessments.
Common symptoms include fever, headache, neck stiffness, nausea, vomiting, and altered mental status. Some patients may also experience seizures.
Diagnosis is typically made through clinical evaluation and confirmed with lumbar puncture, showing pleocytosis and positive PCR for HSV.
Treatment usually involves antiviral medications such as acyclovir, especially if diagnosed early.
Currently, there is no vaccine available for herpes simplex virus, making preventive measures essential.
