What to do when you turn 65: a simple step-by-step Medicare checklist
Turning 65 sets a Medicare clock ticking, and a few early decisions shape your costs and coverage for years. Here is exactly what to do, in plain English and in the right order.
Short answer
When you turn 65, your Initial Enrollment Period opens for 7 months: the 3 months before your birthday month, your birthday month, and the 3 months after. During that window you enroll in Medicare Part A and Part B, then decide whether to add a Medicare Advantage plan, a Medicare Supplement (Medigap) plan, and a Part D prescription drug plan. Acting early helps you avoid late penalties and keep the widest choice of plans.
If you are approaching 65, you have probably noticed Medicare is full of parts, letters, and deadlines that nobody fully explains. The good news: you do not need to learn all of it. You need to do a handful of things in the right order, at the right time. This checklist walks you through it.
When does the Medicare clock actually start?
Your Initial Enrollment Period is a 7-month window built around your 65th birthday. It begins 3 months before the month you turn 65, includes your birthday month, and runs 3 months after. Enrolling in the first 3 months means your coverage can start the month you turn 65, which is why acting early matters.
There is one common exception. If you or your spouse are still working and you have qualifying health coverage through that job, you may be able to delay parts of Medicare without a penalty. This is one of the easiest places to make an expensive mistake, so it is worth confirming your specific situation before you delay anything.

Mark your enrollment window on the calendar
Find the month you turn 65 and count back 3 months. That is when your window opens. If you want coverage active on your birthday, aim to enroll in those first 3 months.
Check whether you should enroll now or delay
If you are retired or do not have employer coverage, you generally enroll now. If you or your spouse are still working with group coverage, confirm whether delaying is safe for your situation before you skip anything.
Enroll in Original Medicare (Part A and Part B)
Part A covers hospital care and is premium-free for most people. Part B covers doctor visits and outpatient care and has a monthly premium. Together they are the foundation everything else builds on.
Decide how you want to fill the gaps
Original Medicare does not cover everything. You generally choose one of two paths: a Medicare Advantage plan that bundles coverage, or a Medicare Supplement (Medigap) plan paired with a separate drug plan. This is the biggest decision, and it is where personal guidance helps most.
Sort out prescription drug coverage (Part D)
If your path does not already include drug coverage, add a stand-alone Part D plan. Match it to the specific medications you take, because the right plan depends on your drug list and pharmacy.
Review it once a year
Plans, networks, and drug formularies change every year. A quick annual review during the fall enrollment period keeps you from quietly overpaying or losing access to a doctor or medication.

The most common mistakes people make at 65
You can sidestep most Medicare headaches by avoiding a few predictable missteps:
- Missing the enrollment window. Late enrollment can mean lasting penalties added to your premium.
- Assuming Medicare is free. There are premiums and real coverage gaps to plan for.
- Picking a plan without checking your doctors and drugs. Networks and formularies vary, so the "best" plan is the one that fits your actual care.
- Choosing based on one company's pitch. A captive agent can only show you their plans. An independent agent compares across carriers.
- Setting it and forgetting it. Plans change yearly, so skipping the annual review can cost you.

Frequently asked questions about turning 65 and Medicare
How many months do I have to sign up for Medicare at 65?
You have a 7-month Initial Enrollment Period: the 3 months before your birthday month, your birthday month itself, and the 3 months after. Enrolling in the first 3 months helps your coverage start as early as possible.
Do I have to take Medicare at 65 if I am still working?
Not always. If you or your spouse have qualifying coverage through a current employer, you may be able to delay certain parts without a penalty. Because the rules depend on your specific coverage, it is worth confirming before you delay anything.
What happens if I miss my Medicare enrollment window?
Missing your window can lead to late enrollment penalties that are added to your premiums, sometimes for as long as you have coverage. You may also have to wait for a general enrollment period to sign up, which can delay your coverage.
Is Medicare Advantage or Medicare Supplement better when I turn 65?
Neither is universally better. Medicare Advantage often has lower monthly cost but uses provider networks. A Medicare Supplement usually costs more monthly but offers broad provider access and predictable costs. The right choice depends on your budget, your doctors, and how much you travel.
How much does Medicare cost when you turn 65?
Part A is premium-free for most people who paid Medicare taxes while working. Part B has a standard monthly premium that can be higher for higher incomes. Any Advantage, Supplement, or drug plan you add has its own cost. Your total depends on the combination you choose.
Do I need a separate prescription drug plan?
It depends on your path. Many Medicare Advantage plans include drug coverage, while Original Medicare with a Supplement usually does not, so you would add a stand-alone Part D plan. The best plan is the one matched to the specific medications you take.
Can someone help me compare my Medicare options for free?
Yes. A licensed independent agent can compare options across multiple carriers and explain them in plain English at no cost to you. You can also download the free guide above to get oriented first.
