ICD-10 Code A92.5 – Zika virus disease (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A92.5 – Zika virus disease
What it is
A92.5 identifies Zika virus disease, an acute viral infection caused by Zika virus. Use it when the record documents confirmed or clinically diagnosed Zika infection.
Clinical signs
Common features include fever, rash, conjunctivitis, arthralgia, and myalgia. Clinical features vary; refer to documentation, especially when the presentation overlaps with other arboviral illnesses.
When to use this code
Use A92.5 when the provider diagnoses Zika virus disease or documents a positive Zika infection with compatible illness. It may also apply when the chart clearly links symptoms to Zika rather than another cause. Code the condition as documented; check documentation if the diagnosis is uncertain.
Do not use for
Do not use this code for suspected exposure without illness or for nonspecific viral syndrome without a Zika diagnosis. Do not assign it when another mosquito-borne infection is documented instead.
Coding tip
Verify that the note states Zika virus disease, not just travel exposure or testing, before assigning A92.5.
