    Question Modifier 21

    AAPC: Back to School
    I received a publication that stated the modifier 21 could only be used with the highest level E/M services, such as 99205 or 99215. Can this code not be used with all E/M services at the highest level?

    I was taught the same thing regarding use of modifier 21 - that it can only be used when "the E/M service is prolonged or the service is otherwise greater than that usually required for the highest level of E/M service within a given category".
