Thread: coding anesthesia for AA directing CRNA's

    Question coding anesthesia for AA directing CRNA's

    AAPC: Back to School
    My question is that is it correct to use the QK and the QY modifier for
    Medicare on the same procedure when there is a CRNA also billing?
    (ie.) The AA bills 00840 -QK,QY, GC and the
    CRNA bills 00840 -QX,GC

    I think that the QK modifier is indicating that the AA is overseeing 2 or more
    cases and that the QY modifier is indicating that he is only overseeing 1 CRNA case at the same time. Too me it seems that the modifiers are conflicting. Can you help me understand this?

    If the anesthesiologist medically directed the CRNA and only that one CRNA, you will use a QY for the anesthesiologist and a QX for the CRNA.
    If the anesthesiologist is medically directing more than one CRNA, you would then use a QK for the anesthesiologist and a QX for the CRNA
    If the CRNA was not medically directed at all, you would then use the QZ modifier indicating the service was without medical direction by a physician.

    I hope this helps.
