ICD-10 Code J10.2 – Influenza due to other identified influenza virus with gastrointestinal manifestations (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J10.2 – Influenza due to other identified influenza virus with gastrointestinal manifestations
What it is
This code identifies influenza caused by an identified influenza virus, with gastrointestinal symptoms such as nausea, vomiting, or diarrhea. Use it when the record links the flu infection to GI manifestations.
Clinical signs
Typical findings include acute influenza illness with respiratory symptoms plus gastrointestinal complaints. Clinical features vary; refer to documentation, and confirm the provider documented the viral type and GI manifestations.
When to use this code
Use J10.2 when the clinician documents influenza due to another identified influenza virus and notes gastrointestinal manifestations. It is appropriate for confirmed influenza cases where the GI symptoms are part of the documented presentation. Check documentation if the virus type is not specified.
Do not use for
Do not use this code for influenza without gastrointestinal manifestations or when the virus is not identified. If the record only says “flu-like illness,” check documentation.
Coding tip
Code the documented influenza virus type first, and make sure the gastrointestinal manifestations are explicitly tied to the infection.
