Influenza virus in non-flu diagnoses
Usually what is a flu dx coded as? Template:Discussion
- When a patient has pneumonia with the infulenza virus but also has a positive bacterial culture, you can code pneumonia twice using the pathogen of influenza virus for one entry and the bacterial pathogen for the other.
- If a patient has a positive swab for influenza but does not have pneumonia (clear CXR), 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 pathogen. (This directive was given by Dr. Kumar). --LKolesar 10:39, 2015 February 4 (CST)
