During an open enrollment period, you can review, change, or enroll in health insurance and other benefits (like dental, vision, life insurance, retirement) for the upcoming year, typically happening in the fall, with coverage often starting January 1st. It's a chance to adjust plans due to life changes or simply to shop for better options, but missing the deadline usually means waiting until the next year, unless a qualifying event triggers a Special Enrollment Period (SEP).
The three main Medicare enrollment periods are the Initial Enrollment Period (IEP) for first-time sign-ups around age 65, the Annual Enrollment Period (AEP) from October 15 to December 7 for yearly plan changes, and the Special Enrollment Period (SEP) for unique life events, plus the General Enrollment Period (GEP) (Jan 1 - Mar 31) for those who missed their IEP and need Original Medicare.
If you waited 2 full years (24 months) to sign up for Part B and didn't qualify for a Special Enrollment Period, you'll have to pay a 20% late enrollment penalty (10% for each full 12-month period that you could have signed up), plus the standard Part B monthly premium ($202.90 in 2026).

If you start SS benefits after turning 65 or aren't collecting any SS benefits when you turn 65, you'll need to sign up for Medicare yourself during your Initial Enrollment Period (IEP).
