You qualify for your initial enrollment period for Medicare Parts A and/or B. This is a 7 month rolling window based on your birthday month. This period includes 3 months prior to the month you turn 65, the month of your birth and 3 months after. Please note if you were born on the 1st day of the month, your 7 month window starts a month earlier. In most cases, you will want to enroll for both Medicare Part A and B.
On average, Medicare Enrollment takes 2-4 weeks to process. If you are already on Social Security your enrollment is automatic, you do not need to apply and you will receive a Medicare card automatically.
Note: Different dates may apply if you are under age 65 and if you have been on Social Security Disability for at least 24 months.
