West Nile virus infection with oth neurologic manifestation

This code signifies a confirmed West Nile virus infection where the patient presents with neurological symptoms beyond meningitis or encephalitis, such as acute flaccid paralysis, optic neuritis, or polyradiculopathy. It indicates the systemic viral infection has progressed to affect the nervous system in a specific, non-meningoencephalitic manner.

Apply this code when documentation clearly states a West Nile virus infection and describes neurological manifestations other than meningitis or encephalitis. This includes conditions like West Nile poliomyelitis, ataxia, or cranial nerve palsies. Physician documentation of a positive West Nile virus test and the specific neurological sequelae is essential.

• Distinguish carefully from West Nile fever (A92.30), West Nile meningoencephalitis (A92.31), and West Nile fever with meningitis (A92.39).
• Ensure the medical record explicitly details the "other" neurologic manifestation to support this specific code.
• Code any associated neurological conditions (e.g., G04.89 for other viral encephalitis) as secondary diagnoses if applicable and supported.
