ICD-10 Code A98.2 – Kyasanur Forest disease (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A98.2 – Kyasanur Forest disease
What it is
A98.2 identifies Kyasanur Forest disease, a tick-borne viral hemorrhagic fever. Use it for documented infection with this specific virus, not for nonspecific febrile illness.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include acute fever, headache, myalgia, and bleeding manifestations in severe cases, but you should code only what is confirmed.
When to use this code
Use A98.2 when the provider documents Kyasanur Forest disease, Kyasanur Forest virus infection, or confirmed disease due to this agent. It is appropriate for encounter records that clearly identify the diagnosis. If the chart only says viral fever or suspected arboviral illness, check documentation before assigning this code.
Do not use for
Do not use this code for other tick-borne diseases, generic viral hemorrhagic fevers, or fever of unknown origin. If the diagnosis is not specifically Kyasanur Forest disease, select the documented condition instead.
Coding tip
Code only when the provider names the disease or a confirmed equivalent; otherwise, verify the record and avoid guessing.
