Turning 65? Your Medicare checklist

Advantage vs. Supplement, Part D, enrollment windows — a simple, step-by-step guide so you don’t miss a deadline or overpay for coverage.

Turning 65 comes with one of the more confusing decisions you’ll make about your healthcare: Medicare. There are parts labeled with letters, enrollment windows with real deadlines, and a fork in the road between two very different ways to get your coverage. Let me make it manageable.

First, understand the four parts

Part A covers hospital stays. For most people it’s premium-free because you paid into it while working.
Part B covers doctor visits and outpatient care, and it has a monthly premium.
Part C is Medicare Advantage — a private alternative that bundles A, B, and usually D together.
Part D covers prescription drugs.

Know your enrollment window

Your Initial Enrollment Period is a seven-month window: the three months before the month you turn 65, your birthday month, and the three months after. Signing up during this window helps you avoid late-enrollment penalties, which can stick with you for as long as you have coverage. This is the single most important deadline to protect.

If you’re still working at 65 with employer coverage, the rules can differ — sometimes you can delay without penalty. That’s worth confirming for your specific situation rather than guessing.

The big fork: Advantage vs. Original Medicare + Supplement

This is the decision that trips up the most people. You generally choose between two paths:

Medicare Advantage (Part C): An all-in-one plan from a private insurer, often with low or no additional premium and extra perks like dental or vision. The trade-off is that you typically use a network of providers and may need referrals.
Original Medicare + a Supplement (Medigap) + Part D: This path lets you see nearly any provider that accepts Medicare, with a Supplement policy covering many of the out-of-pocket costs. It usually costs more in premiums but offers more predictability and flexibility.

Neither is universally better. It comes down to your doctors, your prescriptions, your budget, and how much you value flexibility versus lower monthly cost.

Don't forget your prescriptions

If you go the Original Medicare route, you’ll want a standalone Part D plan for drug coverage. Even if you take few medications now, enrolling on time avoids a lifelong penalty later. Plans differ in which drugs they cover and at what cost, so it’s worth matching a plan to your actual prescriptions.

Your quick checklist

Mark your seven-month enrollment window on the calendar.
Decide whether you’re delaying due to employer coverage — and confirm the rules.
Enroll in Part A (and Part B unless you’re delaying).
Choose your path: Advantage, or Original + Supplement + Part D.
Match a drug plan to your actual medications.
Review your choice each year during open enrollment — plans change.

Medicare feels overwhelming because it's a lot of decisions at once. Taken one step at a time, it's very manageable.

I help people walk through exactly this every year, in plain language, with no pressure toward any particular plan. If you’re approaching 65 — or helping a parent who is — let’s map out the right path for your situation before any deadlines sneak up.
