Thread: Modifer 59,79, or none?

    Question Modifer 59,79, or none?

    AAPC: Back to School
    If a patient received a surgery with a 90 day global, goes onto the recovery floor, then later on comes back to the operating room for a different procedure, should I use modifier 59 or 79? Should I bill the two different CPT codes on separate or different invoices?

    Thank you for your help!

    if the second procedure is related to the first then it is a 78 if the second procedure is unrelated then it is a 79.

    Thanks to both of you, the appropriate modifier is 78.

    Do you suggest using a separate invoice?

    Have a great weekend!
