ICD-10 Code A92.0 – Chikungunya virus disease (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A92.0 – Chikungunya virus disease
What it is
A92.0 identifies chikungunya virus disease, a mosquito-borne viral infection. It is used when the record documents chikungunya infection or illness caused by the chikungunya virus.
Clinical signs
Typical features include acute fever, joint pain, headache, muscle pain, rash, and fatigue. Clinical features vary; refer to documentation.
When to use this code
Use A92.0 when the clinician confirms chikungunya virus disease or documents a current infection due to chikungunya virus. This code fits outpatient, inpatient, or emergency encounters where the diagnosis is established. If the record only says “possible” or “suspected,” check documentation before coding.
Do not use for
Do not use this code for nonspecific viral fever, other mosquito-borne illnesses, or a history of chikungunya without active disease. Check documentation if the diagnosis is uncertain.
Coding tip
Code the confirmed viral diagnosis as documented and verify whether the record distinguishes current infection from past exposure.
