Understanding Initial Enrollment Period (IEP)
The Initial Enrollment Period (IEP) is the 7-month window when you first become eligible for Medicare, typically around your 65th birthday. It includes 3 months before your birthday month, your birthday month, and 3 months after.
During your IEP, you can sign up for Medicare Part A, Part B, Medicare Advantage, and Part D. When your coverage starts depends on which month you enroll.
If you enroll in the 3 months before your birthday month, coverage typically starts the first day of your birthday month. If you wait until your birthday month or later, coverage may be delayed.
Missing your IEP may result in late enrollment penalties and gaps in coverage. If you're still working with employer coverage, you may qualify for a Special Enrollment Period instead.
