Influenza due to other identified influenza virus (J10) ICD-10-CM
The J10 code range covers influenza due to other identified influenza virus with 12 ICD-10-CM diagnosis codes. 9 of them are billable and valid for claim submission in fiscal year 2026, and the category headers group them but cannot themselves be billed.
Includes

- influenza A (non-novel)
- influenza B

Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

About the J10 Code Range
The ICD-10 code J10 covers influenza caused by identified influenza viruses other than type A (H1N1). These codes are used to specify influenza infections confirmed to be from distinct viruses and to document any associated complications like pneumonia or other respiratory and systemic symptoms.
The codes under J10 differentiate the nature of the influenza infection, such as J10.0 for flu with pneumonia and its subtypes specifying if pneumonia is unspecified (J10.00), caused by the same virus (J10.01), or another specified pneumonia (J10.08). Other codes classify flu with additional respiratory symptoms (J10.1, including "upper respiratory tract infection caused by influenza virus"), gastrointestinal issues (J10.2, like influenza-related gastroenteritis), or rare complications like encephalopathy (J10.81) and myocarditis (J10.82). The code J10.83 describes flu with otitis media, commonly linked to influenza viruses including subtype H1N1. These specific ICD-10 codes for influenza help clinicians and coders accurately report the particular virus involved and the extent of illness, facilitating targeted treatment and reliable health records.
