ICD-10 Code B10.82 – Human herpesvirus 7 infection (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B10.82 – Human herpesvirus 7 infection
What it is
B10.82 identifies an infection caused by human herpesvirus 7, a herpesvirus linked to primary or active infection. Use it when the record specifically documents HHV-7 infection.
Clinical signs
Clinical features vary; refer to documentation. Reported findings may include fever, rash, lymphadenopathy, or other nonspecific viral illness signs, but the diagnosis should be supported by the provider’s note.
When to use this code
Use B10.82 when the clinician documents human herpesvirus 7 infection as the confirmed diagnosis, whether acute, primary, or otherwise specified. It may also apply when the chart clearly links symptoms to HHV-7. If the organism is not named, check documentation.
Do not use for
Do not use this code for nonspecific viral syndromes, fever of unknown origin, or herpesvirus infections not identified as HHV-7. If the record mentions another herpesvirus, code that documented condition instead.
Coding tip
Code only when HHV-7 is explicitly stated in the provider documentation or confirmed in the record.
