ICD-10 Code B06.02 – Rubella meningitis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B06.02 – Rubella meningitis
What it is
B06.02 identifies meningitis caused by rubella infection. Use it when the record documents rubella with meningeal involvement, not uncomplicated rubella.
Clinical signs
Clinical features vary; refer to documentation. Typical meningitis findings may include headache, neck stiffness, fever, photophobia, or abnormal cerebrospinal fluid results, with rubella noted as the cause.
When to use this code
Use this code when the provider clearly documents rubella meningitis or meningitis due to rubella. It fits inpatient, outpatient, or emergency records when the diagnosis is established or treated as confirmed. Check documentation if the note only says suspected viral meningitis.
Do not use for
Do not use it for uncomplicated rubella, encephalitis, or meningitis from another infectious agent. If the chart does not specify rubella as the cause, check documentation.
Coding tip
Code the documented cause first and confirm that meningitis is explicitly linked to rubella before assigning B06.02.
