ICD-10 Code A92.32 – West Nile virus infection with other neurologic manifestation (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A92.32 – West Nile virus infection with other neurologic manifestation
What it is
A92.32 identifies West Nile virus infection when the illness includes a neurologic complication not captured by a more specific West Nile code. Use it when documentation links West Nile infection to other nervous system involvement.
Clinical signs
Clinical features vary; refer to documentation. Neurologic manifestations may include meningitis, encephalitis, acute flaccid weakness, tremor, confusion, or other central or peripheral nervous system findings.
When to use this code
Use this code when the provider documents West Nile virus infection with a neurologic manifestation that is not better specified elsewhere. It may apply after laboratory confirmation or a clear clinical diagnosis supported by the record. Code the documented neurologic complication as recorded.
Do not use for
Do not use A92.32 for uncomplicated West Nile virus infection or for a different, more specific West Nile neurologic code. If the neurologic diagnosis is unclear, check documentation.
Coding tip
Confirm that the record explicitly connects West Nile infection to the neurologic manifestation before assigning A92.32.
