ICD-10 Code G00.3 – Staphylococcal meningitis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G00.3 – Staphylococcal meningitis
What it is
G00.3 identifies meningitis caused by Staphylococcus species. Use it when documentation states staphylococcal meningitis or a staphylococcal organism as the cause of the meningeal infection.
Clinical signs
Clinical features vary; refer to documentation. Typical meningitis findings may include fever, headache, neck stiffness, altered mental status, or other signs of meningeal irritation.
When to use this code
Use this code when the provider specifically documents staphylococcal meningitis, including confirmed culture or clearly stated organism attribution. It may also apply when the record links meningitis to Staphylococcus aureus or another staphylococcal species. Check documentation if the organism is not explicit.
Do not use for
Do not use G00.3 for meningitis caused by other bacteria, viruses, fungi, or noninfectious conditions. Do not assign it when staphylococcal infection is documented elsewhere but meningitis is not confirmed.
Coding tip
Code the organism only when the record clearly ties Staphylococcus to the meningitis diagnosis; otherwise, query or check documentation.
