H 816 Vermont House · 2025-2026 Regular Session

An act relating to regulating the use of artificial intelligence in the provision of mental health services

H.816 prohibits mental health professionals in Vermont from using artificial intelligence to make therapeutic judgments, diagnoses, treatments, or provide therapeutic communication to clients. It specifically bans advertising or offering mental health services that claim AI provides these clinical functions. The bill allows AI use for administrative tasks like scheduling, documentation, or quality improvement, as long as licensed professionals retain full clinical responsibility. Violations would be enforced under Vermont's Consumer Protection Act, giving the Attorney General authority to take action. This directly affects all mental health service providers, including therapists and clinics, operating within Vermont.

MODERATE
The bill's core regulatory framework was significantly narrowed. The prohibition on AI in mental health settings now requires that AI act 'independently' rather than prohibiting any use, removing bans on direct client interaction and emotion detection. A new definition of 'therapeutic decision' explicitly carves out algorithmic risk scoring and clinical decision support tools used under professional supervision. Consent requirements were also narrowed from covering recording, transcription, and processing to only recording.
SCOPE

The prohibited uses section was substantially narrowed. Previously it banned AI from making therapeutic decisions, directly interacting with clients, generating treatment plans, or detecting emotions or mental states. Now it only prohibits AI that 'independently' makes therapeutic decisions, independently diagnoses, independently determines treatment, or independently generates treatment plans. This allows AI-assisted interaction and emotion detection as long as a professional is involved.

The purpose section removed the word 'qualified' before 'mental health professionals,' broadening the stated scope of who is covered by the act's protective purpose.

DEFINITION

A new definition of 'therapeutic decision' was added, defining it as the final clinical determination regarding diagnosis or selection, modification, or termination of treatment. It explicitly excludes algorithmic risk scoring, data analytics, and other clinical decision support tools when used under the supervision and authority of a licensed mental health professional.

The definition of 'artificial intelligence' was changed from describing a system that perceives an environment through data acquisition to one that 'infers from the input it receives how to generate outputs that can influence physical or virtual environments.' The generative AI definition was also revised to focus on generating synthetic content that emulates training data characteristics.

ELIGIBILITY

The patient consent requirement was narrowed. Previously, consent was required when AI was used to 'record, transcribe, or process identifiable therapeutic communications.' Now consent is only required when AI is used to 'record identifiable therapeutic communications,' removing transcription and processing from the consent trigger.

REQUIREMENT

The standard for permitted AI use changed from the professional retaining 'clinical responsibility' to retaining 'sole responsibility for therapeutic decisions.' Additionally, a new requirement was added that the mental health professional must 'review, modify where necessary, and approve the final product' for all permitted uses.
