When you’re enrolled in Medicare, you’ll get your red, white, and blue Medicare card in the mail. If you're automatically enrolled, you'll get your red, white, and blue Medicare card in the mail 3 months before your 65th birthday or your 25th month of getting disability benefits. Your Medicare card shows that you have Medicare health insurance. It shows whether you have Part A (Hospital Insurance), Part B (Medical Insurance) or both, and it shows the date your coverage starts.
Be sure to carry your card with you when you’re away from home. Let your doctor, hospital, or other health care provider see your card when you need hospital, medical or other health services.
