After you sign up for Medicare online at the Social Security site you will get a confirmation number. Print and save that page that contains your confirmation number as you will need it to check the status of your Medicare application. You will also receive an email with a link to the Social Security site where you can check the status of your application. The email tells you to wait 5 days. What it does not tell you, and it is nowhere on the Social Security site, is that it takes 30 to 60 days to get approved for Medicare. It is sort of misleading in that you think that after the 5 days you might know something about your application, but it takes far longer before you will be approved. That is another reason that it is important to sign up for Medicare 3 months before your 65th birthday!
