LAS VEGAS – Dr. Andrew Diamond, chief medical officer of Amazon One Medical, sat down with MobiHealthNews for an in-person interview on Tuesday here at the 2026 HIMSS Global Health Conference & Exposition to discuss the organization's announcement that its Health AI agent will be available on Amazon's website and app for Prime members for free 24/7.
MobiHealthNews: Can you tell our readers about your role at Amazon Health Services?
Dr. Andrew Diamond: I came to Amazon Health Services from One Medical, which is a nationwide primary care practice, and we have long had a relationship between our primary care group and a management services organization that was known as 1Life Healthcare that was acquired by Amazon in 2022.
So, now Amazon provides a lot of the technology infrastructure and the management services to One Medical, which continues to operate primary care clinics – about 200-plus clinics around the country – and then a really strong virtual primary care operation.
That's how I came to Amazon Health Services, but I'm a practicing primary care clinician in internal medicine, and I get to lead the medical team at One Medical as the chief medical officer.
MHN: Amazon Health made a big announcement at HIMSS. Can you tell me about that?
Diamond: The big announcement today is that the AI health agent, which we call Health AI, that we've had open to One Medical members or One Medical patients for the last couple of months, is, as of today, available to everyone in the U.S. who signs up and gets their confirmation email back. So, anybody can use this agent now to get their health questions answered.
MHN: What kind of answers can the agent provide?
Diamond: So it's got a really robust body of health information that it can tap into that's sort of generically available to all, that's not really specific to anyone's particular clinical situation, but if you give it consent to do so, it will go into a health information exchange, or if you're a One Medical patient, it'll go into your One Medical health records and pull in everything that can be known about you and your health, keep that information private and secure, be used only for you and your health and your health needs, and then answer your questions in a much more deeply contextual way.
MHN: Within the last year, Anthropic and OpenAI released their own AI for healthcare. What makes Amazon's Health AI different?
Diamond: A couple of important things. One is that this is the first time that a health AI agent has been developed in deep partnership with a real clinical workforce. So the clinicians of One Medical working with the technologists and the operational leaders at Amazon Health services have co-developed this agent, and for the first time now, if Health AI interactions lead you to needing a licensed healthcare professional, you can be connected directly to someone at One Medical who can then confirm that diagnosis and even get you your treatment, all inside that Health AI context.
So, rather than kicking you out to some other service, or saying, "Hey, you should really see your doctor," you get connected directly to someone who can close the loop for you right there in the Health AI experience.
And then for Prime members, you can actually have that part of the experience where you're going and interacting with a One Medical clinician for 30-plus common healthcare conditions, from hair loss to coughs and colds to allergies, UTIs, etc. You can get that experience as a Prime member up to five times for free.
MHN: Is Health AI now free for everyone?
Diamond: Health AI, the chatbot or the AI agent, is free to everyone. If you need to go on and get care from a licensed healthcare professional, you get that for free up to five times as a Prime member.
