ICD-10 Code J10.8 – Influenza due to other identified influenza virus with other manifestations (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J10.8 – Influenza due to other identified influenza virus with other manifestations
What it is
J10.8 identifies influenza caused by a known influenza virus type, with manifestations other than the standard respiratory or pneumonia patterns. Use it when documentation names influenza and a specific additional manifestation.
Clinical signs
Clinical features vary; refer to documentation. You may see influenza symptoms plus another stated manifestation, such as an atypical complication or associated condition documented by the provider.
When to use this code
Use this code when the record clearly states influenza due to another identified influenza virus and describes an additional manifestation. It is appropriate when the provider links the influenza infection to that manifestation. If the chart only says influenza without a specified virus or manifestation, check documentation.
Do not use for
Do not use J10.8 for influenza caused by an unidentified virus, or when the record does not support a specific identified influenza virus. Do not use it if the documented condition is a different influenza category.
Coding tip
Confirm both the identified influenza virus and the documented manifestation before assigning J10.8.
