When Will I Receive My Medicare Card? 
You will receive your Medicare Card in the mail about three months before your 65th birthday . If you are receiving Social Security or Railroad Retirement benefits at that time , you will automatically be enrolled for both Part A and Part B Medicare . The Part B premium will begin to be deducted from your Social Security check the month that you turn 65 . You can turn down Part B if you wish , but should not do so unless you are receiving health insurance from your employer .
