ICD-10 Code B08.6 – Parapoxvirus infections (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B08.6 – Parapoxvirus infections
What it is
B08.6 identifies infections caused by parapoxviruses, a group of viruses that can produce localized skin lesions in humans. Use this code when the diagnosis is specifically documented as parapoxvirus infection.
Clinical signs
Clinical features vary; refer to documentation. Commonly reported findings include localized papules or nodules on exposed skin, sometimes with crusting or ulceration after animal exposure.
When to use this code
Use B08.6 when the provider documents parapoxvirus infection, such as orf or related parapoxviral disease, and the record supports that diagnosis. It is appropriate when the encounter focuses on the viral skin lesion or confirmed infection. If the organism is not specified, check documentation before coding.
Do not use for
Do not use this code for nonspecific viral rashes, bacterial skin infections, or lesions without a documented parapoxvirus diagnosis. If the chart only says “skin lesion” or “animal bite,” you need clearer documentation.
Coding tip
Confirm the provider names the parapoxvirus infection explicitly before assigning B08.6.
