    Smile Difference between Flu A and B

    Influenza was first diagnosed in the 1930s and has since been classified into three types: A, B and C. Influenza C has never caused a major epidemic, but A and B each have. Also known as the flu, influenza is a highly contagious virus that can have severe complications. The two strands have different biological mechanisms but are largely similar, especially in the symptoms.

    I'm using 487.1 for Influenza unspecified or Flu and 488.02 for type A and B. Please correct me if I'm wrong. Open for suggestions.
    Thanks

    Default Coding for influenza's

    March 15, 2010 Coding for H1N1 Flu For The Record Vol. 22 No. 5 P. 28
    H1N1 flu is assigned to ICD-9-CM code 488.1, Influenza due to identified novel H1N1 influenza virus. According to current coding guidelines, only confirmed H1N1 flu cases are assigned to this code. A confirmed case does not require a positive laboratory finding, but it does require physician documentation that a patient has H1N1 flu (or swine flu). Do not assign 488.1 if the physician documents possible or probable H1N1. Instead, a code from category 487, Influenza, should be used.

    How should we code a diagnosis of influenza type A? Should we report ICD-9-CM code 487.1?
    A: The correct ICD-9-CM code for a patient who has influenza with respiratory manifestations is 487.1. No other code is necessary because 487.1 includes manifestations of laryngitis, pharyngitis, or respiratory infection (upper) (acute).
    However, when a physician documents influenza type A, coders should query to determine whether the patient has one of the following conditions:
    Influenza due to identified avian influenza virus, which includes avian influenza, bird flu, and influenza A/H5N1 (ICD-9-CM code 488.0)
    Influenza due to identified novel H1N1 influenza virus, which includes 2009 H1N1 (swine) influenza virus, novel 2009 influenza H1N1, novel H1N1 influenza, novel influenza A/H1N1, or swine flu (ICD-9-CM code 488.1)
    Neither 488.0 nor 488.1 require an additional code.
