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

What 90849 covers

A mental health clinician leads psychotherapy with members of multiple families in the same session. The work may focus on recurring relationship patterns, family responses to a child’s behavioral or emotional difficulties, or coping approaches shared across families facing similar concerns. The session is psychotherapy, not simply a presentation or general support meeting. Psychiatrists, psychologists, and other qualified mental health clinicians may provide it in an office, clinic, or facility setting.

Choose 90849 when the treatment involves multiple family units participating together, rather than one family meeting with the clinician or a group of individual patients. Document the participating families, the clinical focus, and the therapeutic work performed. Report the session rather than separate units for each family or attendee. CMS assigns work, practice-expense, and malpractice RVUs; its office and facility practice-expense values are distinct.
