WA HB2599

Prohibits AI systems from independently providing mental/behavioral health services in Washington, including making therapeutic decisions, directly interacting with clients therapeutically, generating treatment plans without licensed professional review, or detecting client emotions/mental states

Requires licensed professionals to obtain written informed consent from patients before using AI to record or transcribe therapy sessions, including disclosure of AI use and its specific purpose

Restricts therapy and psychotherapy services to licensed professionals only (psychologists, clinical social workers, mental health counselors, psychiatrists, psychiatric nurses, music therapists, etc.), barring individuals, corporations, or entities from offering such services via AI without proper licensure

Permits AI use for administrative tasks (scheduling, billing, logistics communications) and supplementary support (preparing records, analyzing anonymized data, organizing referrals) when a licensed professional maintains full responsibility

Violations by licensed professionals are subject to discipline under the Uniform Disciplinary Act, and violations of the consumer protection provisions constitute unfair/deceptive trade practices under RCW 19.86
