Recognize pressure
Be cautious about threats to cancel benefits, unexpected requests for your Medicare number, or offers tied to services you did not request. Medicare does not call to sell plans. Limited legitimate callback situations exist, so verify independently.
Use a number you trust
End an uncertain call and use the number on your plan card or official Medicare website. Do not rely on a callback number supplied by the suspicious caller. A trusted person can sit with you while you verify.
Check your records
Compare statements with your calendar and receipts. Ask the provider about unfamiliar charges. If you suspect fraud or misuse of your Medicare number, contact 1 800 MEDICARE and follow its reporting guidance.
Keep a response ready
Try: “I do not share personal information on unexpected calls. I will contact the organization directly.” You do not need to argue. Note the claimed organization and date if you report it.
