If your healthcare business needs to process protected health information (PHI) through OpenAI’s API, you first have to sign a Business Associate Agreement (BAA). To start, email baa@openai.com with your company details and how you plan to use the API. The OpenAI team usually replies in one to two business days, may ask follow-up questions, and wraps up the BAA within a few business days. Most BAA requests get approved. If your use case doesn’t pass the initial review, you can ask for reconsideration only if you’re already working with an OpenAI sales rep or account director. For that, contact sales through https://openai.com/contact-sales or reach out directly to your account director. Almost all API services fall under the BAA, but there are a few exceptions listed at platform.openai.com/docs/guides/your-data. You don’t need an enterprise-level agreement to sign a BAA for the API platform. As for ChatGPT specifically, the article doesn’t mention BAA coverage—so assume the BAA applies to the API services only.
