Medicare open enrollment runs Oct. 15 through Dec. 7, and the choices you make generally apply to your 2027 coverage. More people are turning to AI chatbots to sort through the options, but a new test suggests the exact words you type can change what you see. In a two-month experiment, a Medicare data researcher found that searching for “Medicare plans” mostly returned Medicare Advantage results. Asking about “Medicare options” produced a broader picture that included Special Needs Plans and Medicare Supplement coverage.
That gap matters because most people don’t know Medicare’s vocabulary. A single word could decide whether you ever learn about a plan built for your situation. And AI can sound complete even when important options are missing.
What did the Medicare AI test find?
It found that AI tends to treat Medicare Advantage as if it were Medicare itself. In one test, the researcher created a hypothetical shopper turning 65 who also had Medicaid and was managing type 2 diabetes with medication. The AI correctly recognized at first that a Dual Eligible Special Needs Plan, or D-SNP, could fit someone with both Medicare and Medicaid. But a few steps later, it pointed the shopper to a general Medicare Advantage page and lost the details that mattered most.
Why can AI get Medicare wrong?
Medicare decisions depend on details that AI can drop along the way. Your county, prescriptions, doctors, health conditions, income and plan year all affect which plans make sense. The researcher’s testing flagged other risks too. AI can mix information from different plan years, show plans outside your service area or list benefits that don’t match a specific plan.
How many people use AI for health questions?
More than you might think. About one in six U.S. adults use AI chatbots at least once a month for health information and advice, according to a 2024 KFF poll. Most people aren’t confident those answers are accurate, including a majority of the people who use the tools. The same poll found that Black and Hispanic adults were somewhat more likely than white adults to trust health information from chatbots. That makes double checking even more important for Black families, who are already navigating a system that hasn’t always served them well.
How should you use AI for Medicare open enrollment?
Use it as a starting point, not a final answer. AI can help explain unfamiliar terms like Medigap, Part D or D-SNP. When you ask a question, be specific. Ask it to explain all the major types of Medicare coverage, not just “plans.” Include your county, the 2027 plan year, your medications, your doctors and whether you have Medicaid or other coverage. Then treat the answer as a list of questions to confirm, not a decision.
Where can you double check Medicare information?
Go straight to official sources. Medicare’s online plan comparison tool at Medicare.gov lets you enter your prescriptions and pharmacies to see plans that are actually available in your area. You can also call Medicare directly at 1-800-633-4227, which is 1-800-MEDICARE, or get free, unbiased help from your State Health Insurance Assistance Program, known as SHIP. SHIP counselors don’t sell insurance, and they can walk through options with you or a loved one.
Why does this matter for families?
Many older adults lean on children or grandchildren to help them choose a plan, and those helpers are often the ones typing questions into AI. If you’re helping a parent this fall, one small change in wording could surface a plan that saves money or covers a doctor they trust. The right answer is out there. It just may not be the first one a chatbot gives you.
