Meningococcal meningitis, unspecified
ICD-10 A39.5 is a billable code used to indicate a diagnosis of meningococcal meningitis, unspecified.
Meningococcal meningitis is a severe bacterial infection of the protective membranes covering the brain and spinal cord, caused by Neisseria meningitidis. This condition can lead to significant morbidity and mortality if not promptly diagnosed and treated. Symptoms typically include fever, headache, stiff neck, nausea, vomiting, sensitivity to light, and altered mental status. The unspecified designation indicates that the specific serogroup of Neisseria meningitidis is not identified, which can complicate treatment decisions and epidemiological tracking. Diagnosis is primarily through clinical evaluation and confirmed via lumbar puncture, where cerebrospinal fluid (CSF) analysis reveals elevated white blood cell counts, elevated protein levels, and low glucose levels. Rapid initiation of antibiotic therapy is critical, with common regimens including ceftriaxone or penicillin. Vaccination against meningococcal disease is also a key preventive measure, particularly in high-risk populations. Understanding the nuances of this condition, including potential complications such as septicemia and long-term neurological sequelae, is essential for effective management.
Detailed clinical notes on symptoms, laboratory results, and treatment plans.
Diagnosis and management of meningitis in immunocompromised patients.
Documentation must clearly outline the rationale for using the unspecified code.
Comprehensive neurological assessments and imaging results.
Evaluation of patients presenting with neurological deficits and suspected meningitis.
Ensure that neurological findings are well-documented to support the diagnosis.
Used to obtain CSF for analysis in suspected meningitis cases.
Document indication for lumbar puncture and findings.
Ensure that the procedure is justified based on clinical symptoms.
A39.5 should be used when a patient is diagnosed with meningococcal meningitis, but the specific serogroup is not documented. Coders must ensure that clinical documentation supports the use of this unspecified code.
