Thread: modifier 51 or 59?

    Exclamation modifier 51 or 59?

    AAPC: Back to School
    Medicare patient had 2 11301 (shave excisions) done both on same leg. One was .75cm the other .5cm. Patient also had 17000 (AK destruction) done on face. Would I code the one with the highest RVU's first and then use modifier -51 on the other procedures? Or would I use modifier -59? Any comments would be welcome.

    Medicare in our area does not want the -51, so I would use 59.

    When coding a separate lesion - always use modifier -59 for distinct procedural service.
