Thread: Modifier 50 vs LT/RT

  1. #11

    Default RT/LT or 50 modifier

    AAPC: Back to School

    If using RT and LT both instead of a 50 modifier...Do you need to do so on one line or two?

    Rt and LT are anatomic modifiers and you are allowed only one anatomic modifier per line item so use two lines when reporting RT and LT. Technically RT and LT are for facility outpatient and ASC use however many payers do accept them for physician claims due to the clarity they provide. Therefore I would tend to think on the CPC exam the correct answer would be the 50 modifier.
