ICD-10 Code A87.0 – Enteroviral meningitis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A87.0 – Enteroviral meningitis
What it is
A87.0 identifies meningitis caused by an enterovirus. Use it when documentation states viral meningitis due to an enteroviral infection, not when the cause is unspecified.
Clinical signs
Typical findings include fever, headache, neck stiffness, photophobia, and other meningitis symptoms. Clinical features vary; refer to documentation for the confirmed viral cause.
When to use this code
Use A87.0 when the provider documents enteroviral meningitis, enterovirus-related meningitis, or a specific enteroviral cause of viral meningitis. It fits confirmed or clearly stated diagnoses in the record. If the organism is not identified, check documentation before coding.
Do not use for
Do not use this code for bacterial meningitis, other specified viral meningitides, or meningitis with an unspecified cause. If the chart only says “meningitis” or “viral meningitis,” check documentation.
Coding tip
Code A87.0 only when the record links meningitis to an enterovirus; otherwise, use the unspecified or different viral meningitis code supported by documentation.
