Influenza virus
- all types
Was related to H1N1; no new pathogen code was added for swine flu
- When a patient has pneumonia with the inflenza virus but also has a positive bacterial culture, you can code pneumonia twice using the subcode of influenza virus for one entry and the bacterial pathogen for the other entry.
- If a patient does not have pneumonia (clear CXR) but has a positive swab for influenza, you can use tracheobronchitis as the diagnosis with influenza virus as the subcode pathogen. (This directive was given by Dr. Kumar).
- If there are other organs that are suspected to be infected with influenza (ie. viral myocarditis, with a positive influenza swab) Then you can use disseminated infection as the diagnostic code with influenza virus as the subcode pathogen. (This directive was given by Dr. Kumar). --LKolesar 10:39, 2015 February 4 (CST)
