Note
- Coding direction for DAD and NACRS Updated direction: Avian influenza A (any subtype or subtype not specified) is classified to J09 Influenza due to identified zoonotic or pandemic influenza virus. All other identified influenza virus strains are classified to J10.– Influenza due to identified seasonal influenza virus. Please disregard previous direction to classify influenza A (only subtype H5N1) to J09 Influenza due to identified zoonotic or pandemic influenza virus. Zoonotic influenza viruses are influenza type A viruses that are transmitted from animals to humans; they are rarely transmitted from one human to another. Zoonotic influenza is also known as non-seasonal influenza, as it may be transmitted at any time of the year when people are exposed to animal influenza viruses. Seasonal influenza viruses are those that have adapted to humans; they are strains of influenza virus types A and B that cause respiratory illnesses in humans annually. Seasonal influenza spreads between humans and can cause mild to severe illnesses. Seasonal influenza virus strains are classified to J10.– Influenza due to identified seasonal influenza virus. To determine the current status of influenza viruses — that is, whether they are seasonal or non-seasonal — refer to the Global Influenza Programme web page from the World Health Organization (WHO).From J10 Influenza due to identified seasonal influenza virus
- When a respiratory condition is described as occurring in more than one site and is not specifically indexed, it should be classified to the lower anatomic site (e.g., tracheobronchitis to bronchitis in J40).From Chapter 10: Diseases of the respiratory system (J00-J99)
