I'm turning 65.

Here's what you actually have to decide — and the two deadlines that matter right now. You don't need to memorize Medicare. You need to know your next step.

What's actually happening

A few one-time choices cluster around your 65th birthday.

Around the month you turn 65, a short series of decisions open up — and two of them carry deadlines that can quietly cost you for the rest of your life if you miss them. The good news: almost everything else can wait. We'll keep this to what matters right now.

The two deadlines that matter now

Two windows open around your birthday. Both close.

Window 1 · Enrollment

Your Initial Enrollment Period

A 7-month window — the 3 months before your birthday month, the month itself, and the 3 after. Enroll in Part B in this window or you can face a lifetime late penalty added to your premium. Most people apply through Social Security online — it takes about 10 minutes.

Window 2 · Protection

Your Medigap Open Enrollment

A one-time 6-month window (once you're 65 and on Part B) to buy a Supplement with no health questions asked. Miss it, and insurers can charge you more — or turn you down — later.

The decision underneath it all

Everything flows from one fork.

Path A

Original Medicare + a Supplement

See almost any doctor · steadier costs · add a drug plan.
Path B

Medicare Advantage

One private plan · lower premium · networks & approvals.
