Other arthropod-borne viral fevers, not elsewhere classified (A93) ICD-10-CM
The A93 code range covers other arthropod-borne viral fevers, not elsewhere classified with 5 ICD-10-CM diagnosis codes. 4 of them are billable and valid for claim submission in fiscal year 2026, and the category headers group them but cannot themselves be billed.

Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the A93 range.
Colorado Tick Fever
A febrile illness characterized by chills, aches, vomiting, leukopenia, and sometimes encephalitis. It is caused by the COLORADO TICK FEVER VIRUS, a reovirus transmitted by the tick Dermacentor andersoni.
Colorado tick fever virus
A species of COLTIVIRUS transmitted by the tick DERMACENTOR andersonii and causing fever, chills, aching head and limbs, and often vomiting. It occurs in the northwestern United States, except the Pacific Coast.
Vesicular Stomatitis
A viral disease caused by at least two distinct species (serotypes) in the VESICULOVIRUS genus: VESICULAR STOMATITIS INDIANA VIRUS and VESICULAR STOMATITIS NEW JERSEY VIRUS. It is characterized by vesicular eruptions on the ORAL MUCOSA in cattle, horses, pigs, and other animals. In humans, vesicular stomatitis causes an acute influenza-like illness.
Vesicular stomatitis Indiana virus
The type species of VESICULOVIRUS causing a disease symptomatically similar to FOOT-AND-MOUTH DISEASE in cattle, horses, and pigs. It may be transmitted to other species including humans, where it causes influenza-like symptoms.
Vesicular stomatitis New Jersey virus
A species of VESICULOVIRUS causing VESICULAR STOMATITIS primarily in cattle, horses, and pigs. It can be transmitted to humans where it causes influenza-like symptoms.
Vesiculovirus
A genus of the family RHABDOVIRIDAE that infects a wide range of vertebrates and invertebrates. The type species is VESICULAR STOMATITIS INDIANA VIRUS.
About the A93 Code Range
The ICD-10 code A93 covers a group of rare viral infections transmitted by arthropods, such as insects and ticks, that are not classified elsewhere. These include diseases like Oropouche virus disease (A93.0), Sandfly fever (A93.1), and Colorado tick fever (A93.2), among others.
This section is used for coding specific arthropod-borne viral fevers that do not fit into more common categories. For example, the ICD-10 code for Sandfly fever (A93.1) includes infections also known as Neapolitan sandfly fever and Sandfly-borne orbivirus fever. Colorado tick fever (A93.2) refers to viral infection caused by Coltavirus transmitted by ticks. The code A93.8 covers other specified viral fevers caused by various viruses, including Nairovirus diseases, Vesicular stomatitis, and many rarer conditions with multiple synonyms. Using these codes helps healthcare providers accurately document lesser-known, arthropod-transmitted viral infections for diagnosis and billing purposes.
