Sandfly fever

This code represents an acute, self-limiting arboviral illness transmitted by the bite of infected phlebotomine sandflies. Patients typically present with sudden onset of fever, headache, myalgia, and malaise, often without a rash. The disease is also known as pappataci fever or three-day fever.

Assign this code for confirmed cases of sandfly fever based on clinical presentation and epidemiological exposure. Documentation should clearly indicate a diagnosis of sandfly fever, pappataci fever, or three-day fever. This code is appropriate when the specific viral agent is not identified or specified.

• Do not confuse with other arboviral fevers like dengue or West Nile fever; ensure documentation specifies "sandfly."
• If the specific sandfly fever virus (e.g., Sicilian, Naples) is identified, a more specific code from B33.0-B33.4 may be applicable if available.
• Always review the patient's travel history and exposure to endemic areas for supporting documentation.
