ICD-10 Code B06.00 – Rubella with neurological complication, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B06.00 – Rubella with neurological complication, unspecified
What it is
B06.00 identifies rubella infection when a neurological complication is documented, but the specific neurologic condition is not named. Use it for confirmed rubella with nervous system involvement that is otherwise unspecified.
Clinical signs
Clinical features vary; refer to documentation. Neurologic involvement may be noted with rubella infection, such as encephalitic or other nervous system findings, but the chart must support the complication.
When to use this code
Use this code when the provider documents rubella and a neurological complication, yet does not specify the exact neurologic diagnosis. It is appropriate when the record clearly links the neurologic problem to rubella. Check documentation if the complication is described elsewhere or remains uncertain.
Do not use for
Do not use B06.00 for uncomplicated rubella or for rubella with a different documented complication. If the neurologic condition is specified, code the more precise diagnosis instead.
Coding tip
Verify that both rubella and the neurological complication are documented together before assigning this code.
