    Descriptions of these modifiers are in the HCPCS book. Depending on the scope of the anesthesia practice, number of cases the provider is or isn't directing, documentation and state licensing requirements you could be billing any of these modifiers.
    If an MDA is personally performing = AA modifier
    CRNA is personally performing = QZ modifier
    The other modifiers are medical direction and supervision modifiers that would be billed instead of the AA and QZ modifiers.

    Thanks Julie. It's so hard to tell with this documentation... Should I be looking in the anesthesia report, or just the op report? Thanks again!

    Look at the anesthesia record. The op report will be of no assistance in determining personally performed or medically directed anesthesia. Do you have both MD Anesthesiologists (MDA) and CRNAs in your practice?

    Below is the CMS manual link. See page 115 which outlines Anesthesia services billing specifications and modifier definition.
