ICD-10 Code B08.71 – Tanapox virus disease (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B08.71 – Tanapox virus disease
What it is
B08.71 identifies tanapox virus disease, a rare viral infection caused by tanapox virus. It is used when the diagnosis is documented and you need the specific ICD-10-CM code.
Clinical signs
Clinical features vary; refer to documentation. Reported findings commonly include localized skin lesions and mild systemic symptoms, but you should code only what the provider confirms.
When to use this code
Use B08.71 when the medical record specifically states tanapox virus disease or tanapox infection. It is appropriate for confirmed encounters, follow-up visits, or problem-list documentation tied to this diagnosis. If the record is nonspecific, check documentation before coding.
Do not use for
Do not use this code for other poxvirus infections or for a suspected diagnosis without confirmation. If the note names a different viral illness, choose the code that matches the documented condition.
Coding tip
Code the exact viral diagnosis as documented; if the provider uses only a general rash or viral infection term, query for clarification.
