Modifier 57:
Conditions for Use
Published on Tue Feb 28, 2012
To append modifier 57 properly, you must remember these points: The E/M service occurs the day of or the day before a major surgical procedure (a procedure with a 90-day global period). The E/M service must prompt the surgical procedure that follows. The E/M service must be related to the procedure that follows. The same physician (or tax ID) provides the E/M service and the surgical procedure.
