Herpesviral meningitis
Chapter 1:Certain infectious and parasitic diseases
ICD-10 B00.4 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. Symptoms typically include fever, headache, neck stiffness, and altered mental status. Diagnosis is often confirmed through lumbar puncture, revealing pleocytosis with a predominance of lymphocytes and the presence of HSV DNA in the cerebrospinal fluid (CSF). While herpesviral meningitis is generally less severe than bacterial meningitis, it can still lead to significant complications, including seizures, long-term neurological deficits, and in rare cases, death. Treatment usually involves antiviral medications such as acyclovir, which can reduce the severity and duration of symptoms. Vaccination against HSV is currently not available, making prevention strategies focused on reducing transmission risk, particularly in sexually active individuals. Understanding the clinical presentation and management of herpesviral meningitis is crucial for timely intervention and improved patient outcomes.
Detailed patient history, laboratory results, and treatment plans.
Patients presenting with fever, headache, and altered mental status requiring lumbar puncture.
Ensure documentation includes specific viral testing results and treatment response.
Neurological examination findings, imaging results, and CSF analysis.
Patients with neurological deficits or seizures following viral meningitis.
Document any long-term neurological effects for accurate coding.
Used to obtain CSF for analysis in suspected meningitis cases.
Document indication for procedure and findings.
Ensure neurologists provide detailed notes on CSF analysis.
Common symptoms include fever, headache, neck stiffness, nausea, vomiting, and altered mental status.
Diagnosis is typically made through lumbar puncture and analysis of cerebrospinal fluid, looking for pleocytosis and HSV DNA.
Treatment usually involves antiviral medications such as acyclovir, which can help reduce the severity and duration of symptoms.
