Turning 65
Turning 65 doesn't mean you have to do anything yet. For some people it means enrolling right away. For others it means doing nothing for years. The first step is determining which situation you're in.
Do I even need to enroll in Medicare?
If you're already collecting Social Security, you'll be enrolled in Part A and Part B automatically. Your card arrives without you doing anything.
If you're not collecting Social Security, nothing is automatic. You enroll yourself, and the window matters.
If you're still working at 65 with coverage through your employer, you may be able to delay Part B without penalty. Whether you can depends on how many people your employer has. At smaller employers, Medicare generally becomes the primary payer at 65, which means delaying can leave you with gaps you didn't expect.
What if I have insurance through my job?
"Creditable" is a specific term, not a general one. It means your coverage is at least as good as Medicare's, and it's what determines whether delaying costs you a penalty later.
Retiree coverage, COBRA, and marketplace plans often are not creditable for Medicare purposes, even when they feel like real coverage.
Your plan administrator can tell you in writing whether yours is creditable. That's worth confirming rather than assuming, because the penalty for assuming wrong is permanent.
Is my employer health coverage better than a Medicare plan?
If you can stay on your employer plan, the next question is whether you should.
Compare them on what you actually pay and use: the premium, the deductible, what your specific doctors cost under each, what your prescriptions cost under each, and whether your spouse is covered under your current plan and what happens to them if you leave it.
Sometimes staying is clearly better. Sometimes Medicare with a supplement costs less and covers more. The answer turns on your prescriptions, your doctors, and your family situation, which is why it can't be answered in the abstract.
I have Part A and Part B. Now what?
Once you're on Original Medicare, you choose how to handle the gap it leaves.
A Medicare Advantage plan delivers your coverage through a private plan, usually with prescriptions included and a network to work within.
A Medicare Supplement sits alongside Original Medicare and covers costs it leaves behind, with no network and prescriptions handled separately.
Which one fits depends on how you use care. If you see specialists often, travel, or split time between states, that pushes one direction. If you want lower monthly costs and your doctors are local, that pushes another.
Does Medicare cover my prescription medication?
If you go the supplement route, you add a Part D plan separately.
Part D plans differ in which drugs they cover and what tier your specific prescriptions land on. The premium is only part of what you'll pay, and two plans with similar premiums can cost very different amounts depending on what you take.
Medicare Supplement Open Enrollment
When you first enroll in Part B, a window opens. During it, you can buy Medicare Supplement plans sold in your state without answering health questions. You cannot be turned down, and you cannot be charged more because of your health.
That window lasts six months, and it's tied to your Part B start date.
Once it closes, it doesn't reopen. In most states, a company can then review your health history, charge you more based on it, or decline you outright.
For someone with existing health conditions, this window is often the only opportunity they will ever have to get a Medigap plan. It's the most consequential deadline in Medicare, and it passes quietly.
Important Penalties to Understand
Medicare has two late enrollment penalties. They work differently, and both are permanent.
The Part B penalty applies if you go without Part B and without creditable employer coverage. It adds 10 percent to your premium for every full 12-month period you could have enrolled and didn't, and it stays on your premium for as long as you have Part B.
The Part D penalty applies if you go 63 days or more without creditable prescription drug coverage after your enrollment period ends. It accrues by the month rather than the year, adding roughly 1 percent of a national base premium for each month you went without. That base is recalculated annually, so the penalty moves with it.
The difference that matters is how they accrue. The Part B penalty builds in full-year blocks. The Part D penalty builds month by month, so even a short gap costs you.
The Part D penalty catches people who take no prescriptions at 65 and decide they don't need drug coverage. Skipping it is what creates the penalty later, when they do need it.
Both are avoidable, and both come down to whether the coverage you already have counts as creditable.
Prepare your checklist
Before speaking to any professional about plan recommendations or Medicare guidance, prepare a list of:
- All physicians and medical groups you frequent
- All prescription medications with dosages
- Any employer insurance details, if applicable
- Your spouse's details, if they're tied to your plan
- A clear, honest list of your personal concerns, such as dental, vision, hearing, home health care, therapies, etc.
Without these, it's impossible to make an informed decision about your senior healthcare outlook. We can determine your options together.
