No. Consumer AI chatbots—including the free and standard paid tiers of ChatGPT, Google Gemini, and similar tools—do not offer Business Associate Agreements. Without a BAA, entering any protected health information into these tools is a potential HIPAA violation, regardless of how the rest of your system is configured.
This is not a technicality. When you type a client's injury details, medical history, or insurance information into a consumer chatbot, that data may be used to improve the AI model, stored on servers without firm-specific access controls, and handled by a vendor with no contractual HIPAA obligations. If that data is ever accessed inappropriately, your firm—not the chatbot provider—bears the liability.
Enterprise API agreements from vendors like OpenAI and Anthropic do include HIPAA BAA options—but BAAs must be explicitly negotiated and signed before any PHI is processed, and the application built on top of the API must also implement all required application-layer safeguards. A BAA from the AI provider alone is necessary but not sufficient.
