    AAPC: Back to School
    Effective date for AI modifier was 01/01/10. The conversations with the ER physician are part of the decision making component of his visit level and then only if documented. The AI modifier is appended to the initial level to identify him as the admitting provider, any work performed to determine the level of service has no bearing on whether to use the AI or not.

    Default A1 vs AI

    A1(one) was effective 1/1/10 for " the principal physician of record". This was for "consult" codes that Medicare does not recognize. AMA corrected this modifier to AI (eye) on the revised corrections document 6/28/11.
