ICD-10 Code G00.2 – Streptococcal meningitis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G00.2 – Streptococcal meningitis
What it is
G00.2 identifies meningitis caused by streptococcal bacteria. Use it when documentation specifies a streptococcal organism as the cause of the meningitis.
Clinical signs
Clinical features vary; refer to documentation. Typical meningitis findings may include fever, headache, neck stiffness, altered mental status, and signs of meningeal irritation.
When to use this code
Use this code when the provider documents streptococcal meningitis, streptococcal meningitis due to a named species, or meningitis with a confirmed streptococcal cause. It applies when the organism is identified or clearly stated in the record. Check documentation if the note only says bacterial meningitis.
Do not use for
Do not use this code for meningitis caused by other bacteria, viruses, fungi, or parasites. Do not assign it when streptococcal infection is elsewhere in the body without meningitis.
Coding tip
Code the specific organism only when the documentation supports streptococcal meningitis; otherwise, query or check documentation before assigning G00.2.
