Which Modifier Should I Use?

Question:

I need some help with using Modifiers. I work for a Mohs surgeon, and he frequently performs Mohs, and the patient comes back differently for a flap or graft. They usually come back within a week. What modifier should I add to the repair when the patient returns?

Answer:

Mohs Micrographic surgery has a global period of “0” days. That means if the patient comes back for the repair on a different date, no modifier is required.
