What 92508 covers
A speech-language pathologist typically uses this service to treat multiple patients in a shared session, working on communication, speech, language, voice, or auditory-processing goals. Group activities may include structured conversation or practice of communication strategies, with skilled direction tailored to each participant. Services are commonly provided in outpatient therapy settings and hospital departments.
Report the group service for each patient who receives it, and document the group format, skilled interventions, individualized goals, and each patient’s participation and response. Choose individual treatment code 92507 when the clinician treats one patient at a time. This is a therapy service, not a separately billed professional component; the professional component modifier does not apply. CMS reduces the practice-expense portion for the second and subsequent therapy units on the same day.
