Nonpyogenic meningitis
ICD-10 G03.0 is a billable code used to indicate a diagnosis of nonpyogenic meningitis.
Nonpyogenic meningitis refers to inflammation of the protective membranes covering the brain and spinal cord (meninges) that is not caused by bacterial infection. This condition can arise from various etiologies, including viral infections, fungal infections, and non-infectious causes such as autoimmune disorders or drug reactions. Clinically, patients may present with symptoms such as headache, fever, neck stiffness, and altered mental status. Diagnosis typically involves a lumbar puncture to analyze cerebrospinal fluid (CSF), which may show lymphocytic pleocytosis, normal glucose levels, and elevated protein levels, distinguishing it from pyogenic (bacterial) meningitis. Treatment focuses on addressing the underlying cause, which may include antiviral or antifungal medications, and supportive care. Nonpyogenic meningitis can lead to complications such as seizures, neurological deficits, or chronic headaches, making early recognition and management crucial.
Detailed neurological examination findings, CSF analysis results, and treatment plans.
Patients presenting with headache, fever, and altered mental status requiring lumbar puncture.
Ensure clear documentation of differential diagnoses and rationale for treatment choices.
Comprehensive history of exposure, laboratory results, and response to treatment.
Patients with suspected viral or fungal infections leading to meningitis.
Document specific pathogens identified and treatment regimens tailored to the infectious agent.
Used to obtain CSF for analysis in suspected meningitis cases.
Document indication for procedure, consent, and CSF findings.
Neurology and Infectious Disease specialists should ensure thorough documentation of the procedure and results.
Common causes include viral infections (like enteroviruses), fungal infections (such as cryptococcal meningitis), and non-infectious causes like autoimmune diseases or drug reactions.
Diagnosis is typically made through lumbar puncture and analysis of cerebrospinal fluid, which shows lymphocytic pleocytosis, normal glucose levels, and elevated protein.
