Meningococcal encephalitis
ICD-10 A39.81 is a billable code used to indicate a diagnosis of meningococcal encephalitis.
Meningococcal encephalitis is a severe neurological condition caused by the bacterium Neisseria meningitidis, which can lead to inflammation of the brain. This condition often arises as a complication of meningococcal meningitis, where the bacteria invade the central nervous system, resulting in encephalitis. Symptoms may include fever, headache, confusion, seizures, and neurological deficits. Diagnosis typically involves lumbar puncture for cerebrospinal fluid analysis, which may reveal elevated white blood cell counts, elevated protein levels, and low glucose levels. Prompt treatment is critical and usually involves intravenous antibiotics such as ceftriaxone or penicillin, along with supportive care. The prognosis can vary based on the timeliness of treatment and the severity of the infection, with potential long-term neurological sequelae in some patients. Vaccination against Neisseria meningitidis is a key preventive measure, particularly in high-risk populations.
Detailed clinical notes on symptoms, lab results, and treatment plans.
Patients presenting with fever, altered mental status, and signs of meningitis.
Need for clear documentation of the causative organism and treatment response.
Neurological examination findings, imaging results, and treatment protocols.
Patients with seizures or altered consciousness due to encephalitis.
Documentation of neurological deficits and follow-up assessments.
Used to confirm the presence of Neisseria meningitidis in cerebrospinal fluid.
Document the source of the culture and results.
Infectious disease specialists should ensure accurate reporting of culture results.
Common symptoms include fever, severe headache, confusion, seizures, and signs of neurological impairment.
Diagnosis is typically made through lumbar puncture, cerebrospinal fluid analysis, and culture to identify Neisseria meningitidis.
Treatment usually involves intravenous antibiotics such as ceftriaxone or penicillin, along with supportive care.
