Medicare Enrollment Timeline
When you can sign up for Medicare depends on your situation — and missing a window can mean penalties or a gap in coverage. This interactive timeline lays out the key dates so you can see exactly where you fall.
Medicare has several enrollment windows, and which one applies to you depends on your age, whether you're still working, and the coverage you already have. The four main ones are your Initial Enrollment Period (the months around your 65th birthday), the General Enrollment Period, Special Enrollment Periods (triggered by life events like leaving an employer plan), and the Annual Enrollment Period each fall, which is mainly for changing or switching plans rather than enrolling for the first time.
Knowing which window you're in matters, because signing up late without qualifying coverage can lead to lasting penalties or a gap before your coverage starts.
Use the interactive timeline below to walk through the key dates and see which periods apply to your situation.
