CPT modifier 57 is used for the initial decision for surgery and should not be used for E/M visits. Underneath the description of modifier 57 and the coding guidelines.
What Is Modifier 57?
Modifier 57 is used when the initial decision to perform a major surgical procedure is made during an E&M service provided the day before or the day of a major surgery. Modifier 57 replaces HCPCS Level II modifier QI (decision for major surgery). Modifier 57 should be used only in cases when the decision for surgery was made during the preoperative period, the day before or the day, of a major surgical procedure (procedures with 90 days of follow-up).
Coding Guidelines For Modifier 57
Modifier 57 should not be used with E/M visits furnished during the preoperative period of minor procedures (0-day or 10-day follow-up period). Use Modifier 25 to report a significant, separately identifiable E/M service by the same physician on the day of a procedure.
