What Is the Medicare Initial Enrollment Period (IEP)?

The Initial Enrollment Period (IEP) is the 7-month window around your 65th birthday when you can first enroll in Medicare Part A and Part B.

Frequently Asked Questions

Does my birthday being on the 1st change anything?
Yes. If you were born on the 1st of the month, Medicare treats your eligibility as starting one month earlier, which shifts your entire IEP one month earlier.
What if I only want Part A?
You can enroll in Part A only during your IEP. Part A is usually premium-free if you or your spouse have enough work credits.
What if I'm already getting Social Security?
You will be automatically enrolled in both Part A and Part B. Your Medicare card will arrive about 3 months before you turn 65.
