I’m turning 65 later this year. When can I enroll in Medicare Part D?

If you are turning 65 you have an Initial Enrollment Period (IEP) of 7 months to enroll in a Part D plan. You can enroll up to 3 months before the month you turn 65, the month of your 65th birthday, and up to 3 months after the month you turn 65. In general, you can switch plans each year during the Annual Enrollment Period (AEP) from October 15 through December 7.
