Specific Coding for Other arthropod-borne viral fevers, not elsewhere classifiedOverview

Non-specific codes like A93 require more characters. Use one of these billable codes instead:

  • Use A93.0 for Oropouche virus disease

  • Use A93.1 for Sandfly fever

  • Use A93.2 for Colorado tick fever

  • Use A93.8 for Other specified arthropod-borne viral fevers

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to A93: its own notes plus those printed at Chapter 1. A note printed at a category, block or chapter applies to every code under it.

Includes

Viral Infections

Viruses are very tiny germs. They are made of genetic material (either DNA or RNA) inside of a protein coating. There are a huge number of viruses on earth. Only a small number of them can infect humans. Those viruses can infect our cells, which may cause disease.
