CPT modifier used for significant, separately identifiable evaluation and management (E/M) service by the same physician on the day of a procedure or other service. The physician may need to indicate that on the day a procedure or service identified by a CPT code was performed, the patient’s condition required a significant, separately identifiable E/M service above and beyond the other service provided or beyond the usual preoperative and postoperative care associated with the procedure that was performed. The E/M service may be prompted by the symptom or condition for which the procedure and/or service was provided. As such, different diagnoses are not required for reporting the E/M service on the same date.
