ICD-10 Code A96 – Arenaviral hemorrhagic fever (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A96 – Arenaviral hemorrhagic fever
What it is
A96 identifies arenaviral hemorrhagic fever, a serious viral illness caused by arenaviruses. Use it for documented arenaviral infection with hemorrhagic fever features, not for nonspecific viral syndromes.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include fever, bleeding manifestations, and systemic illness consistent with hemorrhagic fever caused by an arenavirus.
When to use this code
Use A96 when the provider documents arenaviral hemorrhagic fever or a specific arenavirus causing hemorrhagic fever. Apply it when the diagnosis is established or clearly stated in the record. If the chart only says suspected viral illness, check documentation before coding.
Do not use for
Do not use this code for ordinary viral fever, unspecified hemorrhagic conditions, or non-arenaviral infections. If the organism or syndrome is unclear, check documentation.
Coding tip
Code A96 only when the record links hemorrhagic fever to an arenavirus; otherwise, verify the exact diagnosis first.
