Marburg virus disease

This code identifies a severe, often fatal, hemorrhagic fever caused by the Marburg marburgvirus, a filovirus. It is characterized by sudden onset of fever, severe headache, malaise, and can rapidly progress to gastrointestinal symptoms, rash, and multi-organ failure with significant bleeding.

Use this code for confirmed cases of Marburg virus infection. Documentation should clearly indicate a positive laboratory diagnosis (e.g., PCR, ELISA) or strong epidemiological evidence in a patient presenting with the characteristic clinical syndrome. This code is appropriate for both initial diagnosis and subsequent encounters related to the acute illness.

• Ensure documentation specifies "Marburg virus" to differentiate from other viral hemorrhagic fevers.
• Sequence this code as the primary diagnosis when it is the reason for the encounter.
• Do not confuse with Ebola virus disease (A98.4), which is caused by a different filovirus.
