2025 ICD-10-CM code J09.X2
Influenza due to identified novel influenza A virus with other respiratory manifestations.
Medical necessity is established by the signs, symptoms, and laboratory confirmation of infection with a novel influenza A virus.The presence of other respiratory manifestations further supports the use of this code.
Clinicians are responsible for accurately diagnosing the specific type of influenza, distinguishing novel influenza A from other types, and documenting the presence of other respiratory manifestations.

- J09 - Influenza due to certain identified influenza virusesJ09.X - Influenza due to identified novel influenza A virusJ09.X2 - Influenza due to identified novel influenza A virus with other respiratory manifestations
In simple words: This code refers to the flu caused by a new type of influenza A virus, with symptoms like cough, sore throat, or runny nose.
Influenza due to identified novel influenza A virus with other respiratory manifestations. This includes:* Influenza due to identified novel influenza A virus NOS* Influenza due to identified novel influenza A virus with laryngitis* Influenza due to identified novel influenza A virus with pharyngitis* Influenza due to identified novel influenza A virus with upper respiratory symptomsUse additional code, if applicable, for associated:* Pleural effusion (J91.8)* Sinusitis (J01.-)
Example 1: A patient presents with fever, cough, and sore throat.Testing confirms infection with a novel influenza A virus., A patient with a confirmed novel influenza A virus infection also exhibits laryngitis., A patient diagnosed with a novel influenza A virus infection develops pharyngitis and upper respiratory symptoms.
Documentation should include the type of influenza virus identified (novel influenza A), the specific respiratory manifestations present (e.g., cough, sore throat, runny nose, laryngitis, pharyngitis), and the results of any confirmatory laboratory tests.
** Use additional codes as needed to identify exposure to tobacco smoke and tobacco use/dependence (as described in the chapter guidelines), and for any associated conditions like pleural effusion or sinusitis.
