What 90834 covers

This service is an individual psychotherapy session in which a clinician uses techniques such as cognitive behavioral therapy, supportive therapy, or insight-oriented work to treat a mental health or substance use condition. The patient participates for all or part of the session; a family member or caregiver may join. Clinical psychologists, clinical social workers, psychiatrists, psychiatric nurse practitioners, and Medicare-enrolled marriage and family therapists or mental health counselors provide it in offices, outpatient clinics, and eligible telehealth encounters.

Select 90834 using psychotherapy time: 38 through 52 minutes. Use 90832 for 16 through 37 minutes and 90837 for 53 minutes or more. Document total psychotherapy minutes or start and stop times, the therapeutic approach, clinical focus, patient response, and progress toward treatment goals. Exclude time spent on E/M activities or testing. If the same clinician performs a separately identifiable E/M service with psychotherapy, report the appropriate psychotherapy add-on instead; for 38 through 52 minutes, that is 90836. Interactive complexity add-on 90785 may accompany 90834 when its qualifying communication factors are documented.
