Initial Enrollment Period
What is the Initial Enrollment Period?
Your IEP is a 7-month window centered around your 65th birthday. It's the first and best time to sign up for Medicare Part A and Part B without penalties.
Pro tip: Sign up during the first 3 months of your IEP for the earliest coverage start date.
When were you born?
We only need your birth month and year to calculate your Medicare eligibility dates.
