2025 ICD-10-CM code J09.X
(Active) Effective Date: N/A Diseases of the respiratory system - Influenza due to identified novel influenza A virus J00-J99 Feed
Influenza due to certain identified influenza viruses, such as avian influenza (bird flu), swine influenza, and other novel influenza A viruses.
Medical necessity is established by the presence of signs and symptoms consistent with influenza, along with confirmatory laboratory testing for the identified novel influenza A virus strain, particularly during outbreaks or pandemics.
Clinicians are responsible for diagnosing influenza based on symptoms,performing appropriate tests (e.g. rapid influenza diagnostic tests, viral culture) to identify the specific virus if necessary for public health surveillance or treatment decisions, initiating treatment as appropriate and implementing infection control measures.
In simple words: This code indicates the flu caused by a newly identified influenza A virus, like bird flu or swine flu, that can spread rapidly among people and animals.
This code encompasses influenza caused by specific, identified novel influenza A viruses, including avian (bird), swine, and other zoonotic or pandemic strains, excluding influenza A/H1N1 and other identified or unidentified influenza viruses (J10-J11).
Example 1: A patient presents with fever, cough, muscle aches, and fatigue during an outbreak of avian influenza. Testing confirms infection with an avian influenza A virus., A farmer develops respiratory symptoms after close contact with pigs experiencing an outbreak of swine influenza. Testing identifies the novel swine influenza A virus strain responsible. , A traveler returning from a region with a known novel influenza A virus outbreak presents with flu-like symptoms. Testing confirms infection with the specific novel influenza A virus.
Documentation should include signs and symptoms, such as fever, cough, muscle aches, fatigue, and the results of laboratory testing confirming the specific novel influenza A virus strain. Exposure history (e.g., contact with infected animals or travel to affected regions) should also be documented.
** Consider using additional codes for any complications or related conditions, such as pneumonia or acute bronchitis. Public health reporting of novel influenza A virus infections is often mandatory.
