What This Code Means
A92.32 is the ICD-10-CM diagnosis code for west nile virus infection with other neurologic manifestation. This code describes a West Nile virus infection that has affected the nervous system in ways other than meningitis or encephalitis, such as causing weakness, paralysis, or other neurological complications. West Nile virus is spread by mosquitoes and can cause serious illness affecting the brain and spinal cord. A92.32 sits in the ICD-10-CM chapter for certain infectious and parasitic diseases (a00-b99), within the section covering arthropod-borne viral fevers and viral hemorrhagic fevers (a90-a99).
A92.32 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.
Use this code only when West Nile virus has caused neurologic manifestations that are NOT meningitis (A92.30) or encephalitis (A92.31); document the specific neurologic symptom if possible (e.g., paralysis, weakness).
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for A92.32 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Use this code only when West Nile virus has caused neurologic manifestations that are NOT meningitis (A92.30) or encephalitis (A92.31); document the specific neurologic symptom if possible (e.g., paralysis, weakness)
- •Verify that the diagnosis documentation clearly links the neurologic condition to West Nile virus infection rather than coding them as separate conditions
