I am trying to code a repair. My physician performed one stage of Mohs surgery and the documentation says he did a “purse string repair” How would I code this?
Usually a purse string repair is a simple repair report using a code from 12001-12018. But look carefully at the documentation for the repair. If the physician documents any undermining or extensive instrumentation use the intermediate repair coded 12031-12057. Repairs are coded by anatomic location and size of defect.
