CPT defines modifier 25 as “Significant, separately identifiable evaluation and management service by the same physician on the same day of the procedure or other service.”  It indicates that the patient’s condition required an additional E/M service beyond the usual pre-operative care provided for the procedure or service.  Additional language in CPT emphasizes the importance of chart documentation.  It states, “A significant, separately identifiable E/M service is defined or substantiated by documentation that satisfies the relevant criteria for the respective E/M service to be reported.”  CPT adds that “This modifier is not used to report an E/M service that resulted in a decision to perform surgery.”
