Addition of Appendix T
At its February 2022 meeting, the CPT® Editorial Panel accepted addition of Appendix T. This appendix is a listing of CPT codes that may be used for reporting audio-only services when appended with Modifier 93. Procedures on this list involve electronic communication using interactive telecommunications equipment that includes, at a minimum, audio. The codes listed in Appendix T will be identified with a audio speaker symbol in the 2022 code set. The list of codes contained in the appendix, used with Modifier 93, is effective April 1, 2022.
At its September 2021 meeting, the CPT® Editorial Panel accepted the addition of Modifier 93, which allows reporting of medical services that are provided via real-time interaction between the physician or other qualified health care professional and a patient through audio-only technology. The use of this modifier is effective Jan. 1, 2022.
Modifier 93 descriptor
Synchronous telemedicine service rendered via telephone or other real-time interactive audio-only telecommunications system
Synchronous telemedicine service is defined as a real-time interaction between a physician or other qualified health care professional and a patient who is located away at a distant site from the physician or other qualified health care professional.
The totality of the communication of information exchanged between the physician or other qualified health care professional and the patient during the course of the synchronous telemedicine service must be of an amount and nature that is sufficient to meet the key components and/or requirements of the same service when rendered via a face-to-face interaction.
