Meningococcal meningitis, unspecified
ICD-10 A36.9 is a billable code used to indicate a diagnosis of meningococcal meningitis, unspecified.
Meningococcal meningitis is a serious bacterial infection of the protective membranes covering the brain and spinal cord, caused by the Neisseria meningitidis bacterium. This condition can lead to severe complications, including brain damage, hearing loss, and learning disabilities. The unspecified designation indicates that the specific strain or serogroup of Neisseria meningitidis has not been identified, which can complicate treatment and management. Symptoms typically include sudden onset of fever, headache, stiff neck, nausea, vomiting, increased sensitivity to light, and altered mental status. Diagnosis is confirmed through lumbar puncture and analysis of cerebrospinal fluid (CSF). Treatment usually involves intravenous antibiotics, such as penicillin or ceftriaxone, and may require adjunctive therapies like corticosteroids to reduce inflammation. Early recognition and treatment are critical to improving outcomes and reducing the risk of long-term sequelae.
Detailed clinical notes on symptoms, lab results, and treatment plans.
Diagnosis and management of meningitis cases, including outbreak investigations.
Need for clear documentation of serogroup identification when available.
Comprehensive neurological assessments and follow-up evaluations.
Management of neurological sequelae following meningitis.
Documentation of neurological deficits and recovery progress is crucial.
Used to obtain CSF for analysis in suspected meningitis cases.
Document indication for lumbar puncture and results of CSF analysis.
Infectious disease specialists should ensure that CSF cultures are sent for appropriate testing.
A36.9 should be used when a patient is diagnosed with meningococcal meningitis, but the specific serogroup has not been identified. It is important to ensure that the diagnosis is supported by clinical findings and laboratory results.
