Meningococcal infection, unspecified
ICD-10 A39.9 is a billable code used to indicate a diagnosis of meningococcal infection, unspecified.
Meningococcal infection is caused by the bacterium Neisseria meningitidis, which can lead to serious conditions such as meningitis and septicemia. The infection is characterized by sudden onset of fever, headache, and stiff neck, often accompanied by nausea, vomiting, and sensitivity to light. In severe cases, it can progress rapidly, leading to septic shock and multi-organ failure. The unspecified designation indicates that the specific type of meningococcal infection has not been determined, which may occur in cases where the clinical presentation is ambiguous or when laboratory confirmation is pending. Meningococcal infections are particularly prevalent in crowded settings such as college dormitories and military barracks. Vaccination is a key preventive measure, and treatment typically involves intravenous antibiotics such as penicillin or ceftriaxone. Early recognition and treatment are critical to improving outcomes and reducing the risk of complications.
Detailed clinical notes on symptoms, laboratory results, and treatment plans.
Diagnosis and management of meningococcal infections in hospitalized patients.
Ensure that all relevant laboratory tests and results are documented to support the diagnosis.
Thorough history and physical examination notes, including vaccination status.
Presentation of meningococcal infection in children, particularly in outbreak settings.
Consider age-specific presentation and the importance of vaccination history.
Used when cultures are taken to confirm meningococcal infection.
Document the source of the culture and results.
Infectious disease specialists should ensure cultures are properly documented.
A39.9 should be used when the specific type of meningococcal infection is not documented in the medical record, and further testing is pending.
