Meningitis due to other and unspecified causes
Chapter 6:Diseases of the nervous system
ICD-10 G03 is a billable code used to indicate a diagnosis of meningitis due to other and unspecified causes.
Meningitis due to other and unspecified causes refers to inflammation of the protective membranes covering the brain and spinal cord, which is not attributed to known infectious agents such as bacteria, viruses, or fungi. This condition can arise from various etiologies, including autoimmune disorders, drug reactions, or post-infectious processes. Clinically, patients may present with symptoms such as fever, headache, neck stiffness, altered mental status, and photophobia. Diagnosis typically involves a lumbar puncture to analyze cerebrospinal fluid (CSF), which may show elevated white blood cell counts, protein levels, and decreased glucose levels, depending on the underlying cause. The management of G03 often requires a multidisciplinary approach, including neurologists, infectious disease specialists, and primary care providers, to identify the underlying cause and initiate appropriate treatment. Given the potential for severe complications, including neurological deficits and death, timely diagnosis and intervention are critical.
Detailed neurological examination findings, CSF analysis results, and imaging studies.
Patients presenting with acute onset of headache, fever, and neck stiffness.
Ensure that all differential diagnoses are considered and documented.
Comprehensive history of exposure, laboratory results, and treatment response.
Patients with a history of recent infections or immunocompromised status presenting with neurological symptoms.
Document any infectious workup performed to rule out specific pathogens.
Used to obtain CSF for analysis in suspected meningitis cases.
Document indication for the procedure, consent, and results of CSF analysis.
Neurology and infectious disease specialists should ensure thorough documentation of clinical findings.
G03 should be used when meningitis is diagnosed but the specific cause is unknown or not specified. It is important to document the clinical findings and any tests performed to support this diagnosis.
