ICD-10 Code J10.89 – Influenza due to other identified influenza virus with other manifestations (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J10.89 – Influenza due to other identified influenza virus with other manifestations
What it is
This code identifies influenza caused by a documented influenza virus other than the seasonal strain, when the illness includes manifestations not captured by a more specific influenza code. Use it when the record names the virus and the presentation is described as “other manifestations.”
Clinical signs
Clinical features vary; refer to documentation. Influenza commonly presents with fever, cough, sore throat, body aches, headache, and fatigue, but this code depends on the documented virus and the stated nonstandard manifestation.
When to use this code
Use J10.89 when the provider documents influenza due to another identified influenza virus and does not assign a more specific complication code. It fits cases where the chart supports influenza but the manifestation is not pneumonia, bronchitis, or another separately coded condition. Check documentation if the record is vague.
Do not use for
Do not use this code for influenza without a specified virus, or when the illness is better represented by a more specific influenza complication code. Do not substitute it for unrelated viral syndromes.
Coding tip
Verify both the identified influenza virus and the documented manifestation before assigning J10.89.
