ICD-10 Code A93.8 – Other specified arthropod-borne viral fevers (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A93.8 – Other specified arthropod-borne viral fevers
What it is
A93.8 identifies arthropod-borne viral fevers that do not fit a more specific ICD-10 category. Use it for documented viral febrile illnesses transmitted by insects or other arthropods when the exact syndrome is named as “other specified.”
Clinical signs
Clinical features vary; refer to documentation. Typical references describe acute fever with systemic viral illness, and the record may note exposure to a mosquito, tick, or other arthropod vector.
When to use this code
Use A93.8 when the provider documents an arthropod-borne viral fever that is specified but not separately listed in ICD-10-CM. This is appropriate when the chart names a particular arboviral fever and the coding index directs you here. If the diagnosis is only suspected or the organism is not documented, check documentation before assigning the code.
Do not use for
Do not use this code for a more specific arthropod-borne viral fever that has its own ICD-10 code. Do not use it for nonspecific fever without documentation of an arboviral cause.
Coding tip
Code the specific documented arboviral fever first, and use A93.8 only when no more specific ICD-10-CM option applies.
