ICD-10 Code A98.3 – Marburg virus disease (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A98.3 – Marburg virus disease
What it is
A98.3 identifies Marburg virus disease, a severe viral hemorrhagic fever caused by Marburg virus. Use this code for confirmed or documented Marburg infection, not for nonspecific fever alone.
Clinical signs
Clinical features vary; refer to documentation. Commonly reported findings include acute fever, headache, malaise, vomiting, diarrhea, and later hemorrhagic manifestations or multi-organ involvement.
When to use this code
Use A98.3 when the record states Marburg virus disease, Marburg hemorrhagic fever, or confirmed Marburg infection. It may also apply when the clinician documents a suspected case being managed as Marburg disease, if that is the stated diagnosis.
Do not use for
Do not use this code for undifferentiated viral fever, Ebola virus disease, or other hemorrhagic fevers unless Marburg is specifically documented. Check documentation if the organism is not named.
Coding tip
Code the exact documented viral agent; if the note says only “viral hemorrhagic fever,” you need clearer documentation before assigning A98.3.
