    The AMA has corrected this.

    A1/AI Principal Physician or Record

    Revise modifier A1 to “AI Principal Physician or Record” listed in the front matter for level II HCPCS modifiers

    So, does this mean that a NPP (in this case a PA) bill for an Initial hospital admission with modifier AI?

    Example: Patient seen and admitted by PA, but hospital record and facesheet note a different MD as the admitting doctor, but does not bill admission.

    We have been told by our Medicare carrier that they will pay whether the admitting uses the AI or not. Depending on the patient's problems, you could have 6 different physicians with different specialties billing for 99221-99223.

    Default AI modifier

    Our office sees alot denials because the admitting physicain does not use the AI modifier. What can we do to appeal with Medicare? We have no control over what another physician bills. We are being penalized for smething another physicain is not doing.

    We had to contact the requesting (admitting) physician's coder/billers as they need to send in a corrected claim. Time consuming and frustrating I know, but our MCR carrier wouldn't help us.

    Default ER Visit

    Can an AI modifier be used with an ER visit?
