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.
