    AAPC: Back to School
    does anyone know, when a patient has a procedure (say an excision & they are in a 10 day global period) and they are seen for something else 8 days later that is not related to the excision, what modifier to use? Medicare is denying stating it needs a modifier, i tried 79 and that is not correct. Any suggestions???

    If you are billing an E/M code, you would use modifier 24.

    Hope this helps!

    i don't think this applies b/c we are not an ambulatory sugical center we are a physician's office, thanks though

    Modifier 24 can be used for POS 11(place of service), physician office.



    on the 2nd link, review page 9

    Use the 24 modifier if it an E/M code, I worked at Medicare for 16 years and you should use the 24 mod and your DX must indicate a different DX, and if you have a pt with a chronic condition, use that DX too, ASC has nothing to do with it.

    the 79 is for only surgical codes anyway, hope this helps!!

    if its an E&M code its a 24, but the diagnosis should be different from the global procedure... and hopefully your physician has documented correctly incase you have to sent records.
