Modifier -77 Clarification

    Default Modifier -77 Clarification

    If a different physician applies a skin substitute to a Medicare patient after the physician of record has already applied the first piece of skin, what modifiers are appropriate to use, and when?

    It is my understanding that if the physician stepping in has a locum tenens agreement, the initial treating physician will use the -58 modifier due to global periods for any treatment beyond the initial treatment, and bill as normal for thier claims.

    If physician #2, the physician taking over subsequent treatment in physician #1's absense, does NOT have a locum tenens agreement with provider #1, it would be appropriate to use modifier -77, defined as a repeat procedure by another physician.

    If the physician taking over subsequent treatment DOES have a locum tenens agreement, it would be appropriate to use modifier -77 and modifier Q6.

    Is this correct?

    I would have to agree with you in this scenerio since there is no locum tenens agreement btw the two.
