ICD-10 Code A96.9 – Arenaviral hemorrhagic fever, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A96.9 – Arenaviral hemorrhagic fever, unspecified
What it is
A96.9 identifies an arenaviral hemorrhagic fever when the specific arenavirus is not named in the record. Use it for a documented arenaviral hemorrhagic illness without further subtype detail.
Clinical signs
Clinical features vary; refer to documentation. Typical references describe an acute febrile illness that may progress to bleeding manifestations, weakness, and systemic illness.
When to use this code
Use this code when the clinician documents arenaviral hemorrhagic fever but does not specify the virus or a more precise diagnosis. It also fits cases where the record confirms an arenaviral cause, yet details remain incomplete. Check documentation if the chart only says viral hemorrhagic fever.
Do not use for
Do not use A96.9 for non-arenaviral hemorrhagic fevers or for nonspecific fever without documented hemorrhagic disease. If a specific arenaviral diagnosis is recorded, code that condition instead.
Coding tip
Code the highest documented specificity, and query the provider if the chart names a virus but the final diagnosis is unclear.
