ICD-10 Code A93.0 – Oropouche virus disease (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A93.0 – Oropouche virus disease
What it is
A93.0 identifies Oropouche virus disease, an arthropod-borne viral infection. Use it when the record documents confirmed or suspected Oropouche virus illness.
Clinical signs
Clinical features vary; refer to documentation. Commonly reported findings include acute fever, headache, myalgia, and sometimes rash or other nonspecific viral symptoms.
When to use this code
Use this code when the provider states Oropouche virus disease, Oropouche fever, or a documented Oropouche virus infection. It may also apply when the chart clearly links compatible illness to this virus. If the diagnosis is uncertain, check documentation before coding.
Do not use for
Do not use this code for generic viral fever, unspecified arboviral illness, or other mosquito-borne infections unless Oropouche virus is named. Do not assume the diagnosis from travel history alone.
Coding tip
Code the specific viral diagnosis only when the provider documents Oropouche virus disease; otherwise, query or use the most accurate unspecified code.
