I have a question regarding the appropriate use of modifiers when billing for E/M services performed on the same day as ultrasound procedures (e.g., 93880, 93922, 93978, etc.). Our billing team has been consistently appending modifier 25 to all E/M visits that coincide with same-day ultrasounds, and applying modifier 59 to each ultrasound code. We are a private practice and own the ultrasound equipment, so we do not use modifiers 26 or TC. Could you please confirm whether this approach is correct? Specifically, is it appropriate to routinely apply both modifier 25 to the E/M service and modifier 59 to the ultrasound codes for all in-office visits involving same-day ultrasounds? Thank you in advance for your guidance!
