== Influenza virus ==
This article refers to a '''group''' of influenza pathogens
Usually what is a flu dx coded as?
* See: [https://en.wikipedia.org/wiki/Influenza#Types_of_virus Wikipedia for types of virus included]
*The "flu" is not a diagnostic code, the virus itself is a pathogen, see note below:
**{{discussion}} what main code would one use for "traditional" flu, with an identified flu virus? Would it be simply the appropriate choice in [[:Category:Pneumonia]]?
*See note regarding influenza that is not a pneumonia....use tracheobronchitis code as this is primarily a respiratory infection.  We are not worried about any other symptoms.  If you are asking about gastroenteritis which is sometimes referred to as the flu, we have a code for that. 
*Influenza is only coded if a pt has positive swabs from the cadham lab so influenza is coded as follows:
*When a patient has pneumonia with the influenza 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). --[[User:LKolesar|LKolesar]] 10:39, 2015 February 4 (CST)
** Per Dr Garland, disseminated infection is extremely rare and there should be a positive swab.--[[User:CMarks|CMarks]] 11:50, 2015 May 6 (CDT)
