ICD-10 Code A92.39 – West Nile virus infection with other complications (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A92.39 – West Nile virus infection with other complications
What it is
A92.39 identifies West Nile virus infection when the illness causes complications not named by a more specific code. Use it for confirmed West Nile disease with additional documented problems.
Clinical signs
Clinical features vary; refer to documentation. Commonly reported findings may include fever, headache, myalgia, rash, or neurologic involvement when complications are present.
When to use this code
Use A92.39 when the record confirms West Nile virus infection and the provider documents a complication not captured elsewhere. It fits cases where the chart says “with other complications” or describes an additional manifestation without a more specific option. Check documentation if the complication is unclear.
Do not use for
Do not use this code for uncomplicated West Nile virus infection or for cases with a more specific West Nile diagnosis. If the complication is not documented, or another code better describes the condition, choose that code instead.
Coding tip
Look for the provider’s exact wording on the complication; if it is not specified, you should query or code only what is documented.
