Unspecified viral hemorrhagic fever

This code signifies a diagnosis of viral hemorrhagic fever where the specific causative virus has not been identified. It represents a severe, acute viral illness characterized by fever, hemorrhage, and often shock, without a definitive etiology.

This code is appropriate when a patient presents with symptoms consistent with viral hemorrhagic fever, but laboratory testing or clinical assessment has not yet pinpointed the specific viral agent (e.g., Ebola, Marburg, Lassa). It should be used when documentation clearly indicates a diagnosis of "unspecified viral hemorrhagic fever" or "viral hemorrhagic fever, type unknown."

• Avoid using this code if a more specific viral hemorrhagic fever (e.g., Ebola, Dengue, Lassa) has been documented.
• Query the provider for clarification if the documentation suggests a specific type of viral hemorrhagic fever but does not explicitly state it.
• This code is a last resort when no further specificity can be obtained from the medical record.
