Thread: CRNA modifier

    Default CRNA modifier

    AAPC: Back to School
    Can somebody help me in getting payment for my provider who is a CRNA.

    Medicare is denying all claims with CPT 64450 for missing modifier. If i append modifier QZ than i get the denial that modifier is invalid for the CPT.

    Pleeeeese help me on this.

    Default CRNA modifier

    For code 64450, I would add modifier 59. I also would only bill 64450 if it is for post-op pain, not if it was the mode of anesthesia.

    Modifiers QZ or QX are the only modifiers that you can use for a CRNA on the anesthesia code.

    I am having the same issue, however we are getting a denial saying a modifier is missing even with applying a 59? Has anyone else had this issue?
