Meningococcal meningitis, group A
ICD-10 A36.0 is a billable code used to indicate a diagnosis of meningococcal meningitis, group a.
Meningococcal meningitis caused by Neisseria meningitidis group A is a severe bacterial infection characterized by inflammation of the protective membranes covering the brain and spinal cord. This condition is often associated with high morbidity and mortality rates, particularly in children and young adults. The infection is transmitted through respiratory droplets and can lead to rapid onset of symptoms such as fever, headache, stiff neck, and altered mental status. Early diagnosis and treatment are critical, as the disease can progress quickly to septicemia and shock. Diagnosis is typically confirmed through lumbar puncture and cerebrospinal fluid analysis, which reveals elevated white blood cell counts and the presence of bacteria. Treatment usually involves intravenous antibiotics, such as penicillin or ceftriaxone, and supportive care. Vaccination against group A meningococcal disease is an essential preventive measure, particularly in endemic regions.
Detailed clinical notes, lab results, and treatment plans must be documented.
Patients presenting with fever, neck stiffness, and altered mental status.
Ensure that all diagnostic tests and results are clearly documented to support the diagnosis.
Growth charts, vaccination history, and family history should be included.
Children with sudden onset of fever and neurological symptoms.
Consider age-specific factors and vaccination status when coding.
Used to obtain cerebrospinal fluid for analysis in suspected meningitis cases.
Document indication for the procedure and results of CSF analysis.
Infectious disease specialists should ensure that the procedure is justified based on clinical findings.
Common symptoms include sudden onset of fever, headache, stiff neck, nausea, vomiting, and altered mental status. A rash may also be present in some cases.
