Other specified arthropod-borne viral fevers

This code signifies a febrile illness caused by an arthropod-borne virus that does not have a more specific ICD-10-CM code. It represents viral infections transmitted by vectors such as mosquitoes, ticks, or fleas, where the specific viral agent is identified but lacks a distinct classification within the arboviral fever categories.

Utilize this code when documentation specifies an arthropod-borne viral fever, and the specific virus is known, but no dedicated code exists (e.g., Toscana virus fever, Oropouche fever). This code is appropriate when the physician's diagnosis explicitly states "other specified arthropod-borne viral fever" or identifies a specific arbovirus not otherwise classified.

• Ensure the documentation clearly identifies the viral agent and its arthropod-borne transmission.
• Do not use this code for unspecified arboviral fevers; refer to A94.
• Always sequence this code as the primary diagnosis when it is the reason for the encounter.
