You can enroll in Medicare during the Initial Enrollment Period (IEP), which is a 7-month period that begins 3 months before the month you turn 65, includes the month you turn 65, and ends 3 months after the month you turn 65.
If you miss your IEP, you may still be able to enroll in Medicare during a Special Enrollment Period (SEP). SEPs are available for a variety of reasons, such as moving, losing other health insurance, or going into a nursing home.
You can also enroll in Medicare during the Annual Enrollment Period (AEP), which runs from October 15 to December 7 each year. This is a good time to make changes to your Medicare coverage, such as switching to a different Part D drug plan or adding a Part C Medicare Advantage plan.
