ICD-10 Code A96.1 – Machupo hemorrhagic fever (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A96.1 – Machupo hemorrhagic fever
What it is
A96.1 identifies Machupo hemorrhagic fever, a severe viral hemorrhagic illness caused by Machupo virus. Use this code for confirmed or documented Machupo infection with hemorrhagic fever.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include fever, malaise, bleeding manifestations, and signs of systemic illness in a patient with suspected or confirmed Machupo virus infection.
When to use this code
Use A96.1 when the record specifically states Machupo hemorrhagic fever or Machupo virus infection with hemorrhagic fever. It is appropriate for confirmed diagnoses, including cases documented by the treating clinician or infectious disease specialist. Check documentation if the note only says viral hemorrhagic fever without naming Machupo.
Do not use for
Do not use this code for nonspecific fever, general viral illness, or other hemorrhagic fevers caused by different viruses. If the organism is not identified, check documentation.
Coding tip
Assign A96.1 only when Machupo is explicitly documented; otherwise, code the condition exactly as stated in the chart.
