Medicare Basics

New to Medicare? Start here for plain-English answers to the questions we hear most often.

Why Medicare Feels Confusing at First

Most people’s only real experience with health insurance before Medicare is whatever their employer set up for them — one plan, one card, done. Medicare is different: it’s broken into separate parts (A, B, C, D) that you can mix and match in different combinations, plus an entirely separate layer of optional Supplement plans, each with its own rules about when you can enroll. That’s a lot to take in at once, especially while also making a real decision under a deadline. Our goal on this page and the ones linked below is to walk through it piece by piece, in the order most people actually need it.

The Order We’d Suggest Reading These In

If you’re starting from scratch, we’d suggest working through these roughly in this order: first What Is Medicare to get the big picture, then How to Apply for Medicare so you know your actual deadline, then How Much Does Medicare Cost to set expectations, and finally the individual Part pages if you want more detail on a specific piece. That said, if you already know exactly what you’re looking for, jump straight to it — none of these pages assume you’ve read the others first.

If You’re Turning 65 Specifically

If your 65th birthday is the reason you’re here, our Turning 65: What Are Your Medicare Choices? guide walks through the decision in the order it actually comes up — enrollment timing, working past 65, and the Advantage-vs-Supplement decision — rather than treating each piece separately. A few common situations get their own dedicated guides: what to do if you’re still working past 65, how to apply if you’re not yet collecting Social Security, how to set up automatic premium payments once you have, and how Medicare works with TRICARE For Life if you’re a military retiree.

What Comes After the Basics

Once you understand the basic structure, the real decision most people face is choosing between a Medicare Advantage plan or Original Medicare paired with a Medicare Supplement plan. That’s a bigger, more personal decision than anything covered on these basics pages — it depends on your doctors, your prescriptions, and your budget — which is exactly the kind of conversation we’re glad to have with you directly, free of charge, once you’ve got the fundamentals down.

Questions We Hear Constantly

Do I have to enroll in Medicare if I’m still working at 65?

It depends on the size of your employer and your current coverage. If your employer has 20 or more employees and you have coverage through that job, you may be able to delay Part B without a penalty until that employment ends. Smaller employers often work differently. This is one of the most common things we help people sort out, since getting it wrong can mean a permanent premium penalty.

I have VA benefits — do I still need to enroll in Medicare?

Usually yes, and this is a genuinely common point of confusion — VA health benefits don’t count as the kind of employer coverage that lets you delay Part B without a penalty. See Medicare and the Cincinnati VA for how the two actually coordinate.

What if I already made a mistake with my enrollment?

Reach out anyway. Depending on what happened, there may be a Special Enrollment Period or other option available to fix it, and even if a penalty applies, understanding exactly why helps you avoid repeating it. We’d rather help you sort out a past mistake than have you avoid the conversation out of worry.

Why is my Medicare premium higher than the standard amount?

If your income is above a certain threshold, you may owe an income-related surcharge called IRMAA on top of your standard Part B and Part D premiums. See our plain-English guide to IRMAA for how it’s calculated and what to do if your income has since changed.

Can someone just explain this to me in person?

Yes — that’s most of what we do. These pages are a starting point for reading on your own time, but plenty of people would rather sit down with an actual person and ask questions as they come up. If you’re in Bethel, Cincinnati, or anywhere in Hamilton, Clermont, Butler, or Warren County, we’re glad to do that in person at our office, or over the phone if that’s easier.
