ICD-10 Code J10.1 – Influenza due to other identified influenza virus with other respiratory manifestations (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J10.1 – Influenza due to other identified influenza virus with other respiratory manifestations
What it is
J10.1 identifies influenza caused by a confirmed, other identified influenza virus when the illness includes respiratory manifestations beyond uncomplicated flu. Use it when documentation links the infection to a specific influenza virus type.
Clinical signs
Typical findings include acute influenza symptoms with respiratory involvement such as cough, sore throat, or other upper or lower respiratory features. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents influenza due to an identified influenza virus and notes respiratory manifestations. It fits cases where the record supports influenza with airway or lung involvement, not just nonspecific fever or malaise. Check documentation if the virus type or respiratory complication is unclear.
Do not use for
Do not use J10.1 for influenza without a documented identified virus, or when the chart only states flu-like illness. It is also not the right choice for non-respiratory complications or unrelated respiratory infections.
Coding tip
Verify both the identified influenza virus and the respiratory manifestation before assigning J10.1.
