Unspecified viral hemorrhagic fever (A99)

ICD-10 code A99 is used to classify cases of unspecified viral hemorrhagic fever, a serious viral infection characterized by bleeding and fever. This code applies when the exact virus causing the hemorrhagic fever is not identified.

The term viral hemorrhagic fever refers to a group of illnesses caused by several viruses, which result in fever and bleeding disorders. When a specific virus is not determined, the ICD-10 code A99 is used to document these cases. This code helps healthcare providers and coders report viral hemorrhagic fevers that remain unspecified due to limited diagnostic information, ensuring proper tracking and management of these infections in medical records. Understanding and using this code appropriately supports accurate reporting of viral hemorrhagic fever conditions where further detail about the viral cause is unavailable.
