Oropouche virus disease

This code identifies an infection caused by the Oropouche virus, an arbovirus transmitted by midges and mosquitoes. The disease typically presents with acute febrile illness, headache, myalgia, arthralgia, and sometimes a rash. In some cases, Oropouche virus disease can lead to aseptic meningitis or meningoencephalitis.

Assign this code for confirmed cases of Oropouche virus infection, typically diagnosed through serological testing or PCR. Use when documentation specifies Oropouche virus as the causative agent of the patient's symptoms. This code is appropriate for both initial and subsequent encounters related to the acute infection.

• Ensure documentation clearly specifies "Oropouche virus" to differentiate from other arboviral infections.
• Code any associated neurological manifestations, such as aseptic meningitis (G03.0), as secondary diagnoses.
• Do not use for suspected cases without definitive diagnostic confirmation.
