What This Code Means
A93.0 is the ICD-10-CM diagnosis code for oropouche virus disease. Oropouche virus disease is a rare tropical infection transmitted by insects that causes fever, headache, and joint pain. It is primarily found in Central and South America and is usually self-limiting. A93.0 sits in the ICD-10-CM chapter for certain infectious and parasitic diseases (a00-b99), within the section covering arthropod-borne viral fevers and viral hemorrhagic fevers (a90-a99).
A93.0 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.
This code requires documentation of confirmed Oropouche virus infection; suspected cases should not be coded to this diagnosis without laboratory confirmation.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for A93.0 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •This code requires documentation of confirmed Oropouche virus infection; suspected cases should not be coded to this diagnosis without laboratory confirmation
- •When coding this diagnosis, consider if the patient has traveled to or resides in endemic areas (Central/South America), as this supports the clinical presentation and coding accuracy
