Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 90853 covers

A clinician leads a therapeutic session in which multiple patients work on behavioral health concerns through guided discussion, therapeutic exercises, and interaction with the group. Psychiatrists, psychologists, and other qualified mental health professionals may provide the service in settings such as an outpatient office or hospital outpatient department. The group session is distinct from a meeting limited to multiple families receiving treatment together.

Report 90853 for each patient receiving group treatment, supported by that patient’s record—not once for the group as a whole. Documentation should identify the group service, its therapeutic focus and interventions, and the patient’s attendance, participation, response, and connection to the treatment plan. Select this code for group psychotherapy, not for an individual psychotherapy session or family psychotherapy. CMS assigns work, practice-expense, and malpractice relative values; the practice-expense values differ between office and facility settings.
