What Medicare Actually Looks Like When You’re Still Working at 65
Most people assume Medicare is simple: you turn 65, you sign up, done. But if you’ve spent any time looking into it, you probably already know it’s anything but. There are parts, deadlines, penalties, and a surprising number of ways to make a mistake that follows you for years — or in some cases, for the rest of your life.
Let’s start with the basics, because they matter more than people realize.
Medicare in plain English
Medicare is broken into four parts, and each one covers something different:
Part A covers hospital stays, skilled nursing, and some home health care. For most people it’s premium-free — you paid into it through payroll taxes your whole working life, so when you turn 65 you can sign up for free. Most people go ahead and take it.
Part B covers outpatient care — doctor visits, lab work, preventive services. It comes with a monthly premium ($202.90 in 2026 for most people). This is the one that trips people up on timing.
Part C (Medicare Advantage) is an all-in-one alternative offered through private insurance companies that bundles Parts A, B, and usually D.
Part D covers prescription drugs. It’s a separate plan you add on, and this is the one most people completely forget about with consequences they don’t discover until it’s too late.
Still working at 65? Here’s what you need to know.
If you’re 65 and still working, and your employer offers health insurance, you have options and some of them are actually pretty good.
You can delay Part B without penalty as long as you have qualifying employer coverage. “Qualifying” is the key word here. Your employer’s plan needs to be considered creditable coverage by Medicare standards, which generally means it covers at least as much as Medicare does. Most employer plans from companies with 20 or more employees qualify. If you work for a smaller company, it gets more complicated.
Part A is usually a no-brainer to take even while you’re still working, since it’s free and doesn’t interfere with your employer plan in most situations.
But here’s where people fall through the cracks — and it’s not Part A or Part B.
The Part D mistake that costs people for life
A few years ago a client came to me who had been on Medicare Part A and Part B for four years. He’d done everything right with those two, signed up on time, had his hospital and outpatient coverage in order. But somewhere along the way, Part D never made it onto his radar.
He wasn’t on many prescriptions at the time, so it didn’t feel urgent. He figured he’d add it when he needed it.
When he finally went to sign up for drug coverage, he learned that those four years of going without had come with a price tag. The late enrollment penalty for Part D is 1% of the national base premium for every month you went without creditable drug coverage — permanently added to your premium for as long as you’re on Medicare.
Four years is 48 months. That’s a 48% penalty on his Part D premium. Every month. For the rest of his life.
He wasn’t cavalier about his health, he just didn’t know. And that’s the part that bothers me most. Nobody told him.
What to actually do
If you’re approaching 65, here’s the short version:
- Take Part A. It’s free and there’s almost no reason not to.
- If you have qualifying employer coverage, you can delay Part B but get it in writing that your plan qualifies, and mark your calendar for when you retire so you don’t miss your Special Enrollment Period.
- Don’t ignore Part D. Even if you’re not on any prescriptions right now, look at your options. A low-cost Part D plan now is almost always cheaper than the lifetime penalty you’ll pay for skipping it.
- Call someone who knows Medicare before you make any of these decisions. The SSA website will let you sign up, it will not advise you.

What happens when you’re ready to retire and it’s time to actually activate Part B? There’s a timing detail almost nobody warns you about and I’ve seen it cost clients real money. We’ll cover that in the next issue.
