Eddie and Betty's Conversation
Welcome back to The American Retirement Advisor. I'm here with Eddie, as always, and today we are diving back into Medicare. Specifically, we're in part five of our Healthcare in Retirement series, and this one is about a trap that I think catches a lot of people completely off guard. The trap of thinking you can always change your mind.
Thanks for having me back. And I want to say right up front, this is the episode I wish more listeners heard before they turned 65, because the decisions we're talking about today are ones where the window closes and it does not reopen. Ian Schaeffer laid this out really clearly in his piece, and it's the kind of thing that sounds like fine print until it isn't.
So let's set the scene, because Ian opens with a scenario that I think is going to feel very familiar to a lot of our listeners. You're 65, you pick a Medicare Advantage plan. The premium looks good, it works fine for a few years, and then something changes. The premium goes up, or your doctor leaves the network, or you get a diagnosis and suddenly you want the flexibility of Original Medicare with a Supplement. So you apply for a Supplement. And they say no.
And people are genuinely blindsided by that. There's a woman Ian mentions in the piece who called in after exactly that happened, and her reaction was, we don't even take prescriptions. Like, what? She couldn't understand how she could possibly be turned down. And that confusion makes complete sense if you've been on Advantage, because Advantage has trained you to think you can always make a different choice.
That's the part that I found so striking. You get used to how it works, and you start to assume everything in Medicare works that way.
Right, and that's the core of the misunderstanding. Advantage plans work like an annual subscription. Every fall, October 15 through December 7, you can switch to a different plan, and nobody asks about your health. It's open enrollment, clean slate every year. People internalize that rhythm. And then they apply for a Supplement and hit a completely different kind of system.
So walk me through how Supplements actually work, because I don't think most people know there's a difference in how you get in.
With a Medicare Supplement, also called Medigap, there is one guaranteed door. One. It's the six-month window that starts the first day of the month you turn 65 and are signed up for Part B. During those six months, an insurer has to sell you a policy. They cannot turn you down, and they cannot charge you more because of your health. That window is guaranteed by federal law. And Medicare's own guide is explicit that it is a one-time enrollment period. It does not repeat every year.
One time. So if you were 65 and you went with an Advantage plan instead, that window just closes behind you.
It does. And here's what KFF found, and this number stopped me when I read Ian's piece. Nine in ten enrollees who are 65 and older, and that's 22.4 million people, have no guaranteed right to buy a Supplement beyond certain very specific situations. No automatic door back. They'd have to apply and pass health questions, or qualify under one of the narrow exceptions we'll get to.
22.4 million people. And most of them probably have no idea.
Most of them have no idea. And Ian mentions there are four states that do guarantee it to everyone regardless of health, Connecticut, Massachusetts, Maine, and New York. If you live in one of those states, the rules are different. But Arizona and Nevada, the two states our advisors serve, are not on that list.
There's also something in Ian's piece about people who delayed Part B, maybe because they were still working and had employer coverage. Does that affect any of this?
It does, and this is actually a point of relief for some people. If you delayed Part B because you had qualifying employer coverage, your six-month Medigap window doesn't start until Part B starts. So you didn't lose it. It was waiting for you. Ian ties this back to part two of the series, which is where they covered the rules around delayed enrollment. The window isn't gone, it just hasn't started yet.
Okay. So let's say someone is listening to this and they're thinking, I'm already on Advantage, my first year is still going on. What do they need to know?
That is the most important moment to catch, and federal rules do give you one clean exit from Advantage. It comes in two versions. If you joined an Advantage plan when you first became eligible at 65 and you leave within the first twelve months, you have a guaranteed right to buy any Supplement sold in your state, no health questions asked. Clean exit.
And the second version?
That one covers someone who had a Supplement, dropped it to try an Advantage plan for the first time, and then wants to go back within twelve months. In that case, the insurer has to give you your old policy back, as long as they still sell it. Both of those are trial rights, and both are time-limited. The timing Ian lays out is that you can apply as early as sixty days before your Advantage coverage ends, and no later than sixty-three days after.
So it's not a casual deadline. You have to know those dates and you have to move.
The advisors actually put that date on a calendar the day someone enrolls. Not the day they get frustrated with the plan. The day they enroll. Because by the time frustration sets in, for some people the window has already closed.
Ian has a great quote from an advisor explaining this to a client who was on the fence about trying Advantage. Something like, because it's your first time, you get a twelve-month trial, and if at any time during those twelve months you don't like it, you can switch back with no medical questions asked.
And that framing matters. It makes the trial right feel like a safety net, not a technicality. And the right is real. Ian mentions a client who did exactly that this past summer, used the trial right, came out of an Advantage plan and back onto a Supplement, on schedule. But there's a phrase at the end of that story that shouldn't get buried: the right is real, and it is also once.
Once. Not once a year. Once ever.
Once ever. If you burn it and you're not happy five years from now, there's no second trial right waiting for you.
So what happens to people who are past that first year? Are they completely stuck, or are there other ways in?
There are doors, but Ian is very specific about how narrow they are. Federal law does create some guaranteed-issue situations outside the trial right. Your Advantage plan leaves Medicare entirely, or stops serving your area. You move out of the plan's service area. An employer, retiree, or COBRA plan that was paying after Medicare ends. Your Supplement company goes bankrupt. Or you were misled into joining a plan. Each of those situations opens a door, and each comes with its own sixty-three-day window.
What about if your premium just got too high? Or you got a serious diagnosis and suddenly you need more coverage?
Neither of those is on the list. A rising cost is not a guaranteed-issue trigger. And what you just described, getting hit with a serious condition, that's not a guaranteed-issue trigger either. Ian makes a point of naming those two specifically, because those are the ones people count on. It feels like it should open a door. It doesn't. It's actually the situation where medical underwriting is most likely to work against you.
That is genuinely hard to hear, but it's important. And this connects to something Ian writes that I keep thinking about. There's a couple in the piece, and the husband won't even try an Advantage plan because of this exact fear. He says something like, if I were to go to the Advantage and then try to go back, nobody would want to pick her up. He was protecting his wife.
And Ian says plainly, he was not wrong to worry. That's not paranoia. That's an accurate read of how the underwriting works. Some people's situations, whether it's age, health history, or conditions their spouse has, mean that the trial right is the only safe window. Once it closes, the math changes.
So let's talk about the state-specific piece, because this is where things get interesting. Arizona and Nevada are different from each other on this.
One of them adopted what's called a birthday rule, and it went into effect January 1, 2022. Every year, starting the first day of your birthday month and running for at least sixty days, someone who already has a Supplement can shop for a new Supplement, from any company, with the same or lesser benefits, and no health questions, no rate increase for switching.
That sounds like a really meaningful protection. So every year, around your birthday, you can basically shop around and see if you can get a better price.
You can, and if your premium has crept up over the years, that window is a real opportunity. But Ian is careful to note exactly what that door is and what it isn't. The birthday rule is a door for people who already have a Supplement and want to move to a different Supplement. It does not open a door from an Advantage plan. You have to be holding a Supplement to use it.
So that right only travels with people who are already in that lane. It's a shopping right for people who are already in that coverage.
And that's a big deal for them. But it doesn't change the conversation for someone who went with Advantage at 65 and is now trying to get back to Original Medicare with a Supplement.
And Arizona doesn't have anything like that.
Right, and Ian quotes the state's own SHIP booklet directly on this. Outside the six-month window and a few specific situations, you are subject to medical underwriting, and if you want to change plans in the future, there is no guarantee that you will be able to. That language is from the state's own resource for beneficiaries. It's not a technicality hidden in fine print. Their own guide says it out loud.
So for someone in Arizona, the choice they make at 65 is essentially the choice they live with, unless their health happens to cooperate.
That's what it comes down to. In Arizona, once that first year passes and the specific exceptions don't apply, the question is whether your health profile will pass underwriting. And if a diagnosis has arrived in the meantime, the answer may be no.
There's something in the piece I want to make sure we cover, about how Supplement plans themselves are structured. Because I think people sometimes think Supplement A and Supplement B are like, two companies or two categories.
Good catch. Supplements are standardized by federal law and labeled with letters, A through N. Every insurer selling Plan G is selling the same coverage as every other insurer selling Plan G. The difference is what they charge for it, not what it covers. And Ian mentions that Plans C and F are closed to anyone who became new to Medicare after 2020. The replacements for those are Plans D and G. But the specifics of what each plan letter covers in detail, and how to compare them for any individual situation, that's a question I'd want our team at American Retirement Advisors to walk someone through directly, because it depends on what someone actually needs.
That makes sense. It's not a one-size answer. Okay, let's talk about what a Certified Medicare Planner actually does differently with this, because Ian spends real time on that and I think it's worth unpacking.
The first thing Ian names is that before recommending an Advantage plan at 65, they ask the uncomfortable question out loud. If you wanted a Supplement in five years, could you pass the health questions? Because if the honest answer is no, that changes what makes sense today. Most people are never asked that question. They see a low premium and they sign up.
And asking it requires someone being willing to have a harder conversation than just showing you the monthly cost.
It does. And then there are the things they do after enrollment. The trial-right deadline goes on a calendar immediately, not when the client starts complaining about the plan. For people who are already past the trial right, they know every guaranteed-issue trigger and the sixty-three-day window that goes with it. Ian mentions that some of those triggers open on their own, like a plan leaving the area, and a planner watches for those. In Nevada, they shop the birthday window every year for clients who are already on a Supplement. And they make sure nobody confuses the switch-every-fall rhythm of Advantage with how Supplements work.
That habit of mind is so easy to fall into. Because if you've been on one of those plans for three or four years and you're used to being able to just swap it out each October, it becomes your whole frame of reference. You assume that's just how Medicare works.
And it's a reasonable assumption to make, given the experience. The problem is it's wrong for Supplements, and by the time you find that out, the window may be closed.
So where does this leave someone who's listening right now and trying to figure out where they stand?
Ian ends the piece with a pretty clear way to think about it. If you're on an Advantage plan and your first year is not over yet, the clock matters this month. That trial right is sitting there, but it won't wait. If your first year is already over, the door isn't necessarily locked forever, but you need someone who knows where the other keys are. Those specific guaranteed-issue triggers, the plan-leaving-the-area situations, the birthday window in Nevada. You need someone who's tracking all of it.
And I'd add, even if you think you understand all of this from listening to us today, the specific details of your situation, your state, your current plan, your health history, how close you are to any of these windows, those are questions for an advisor who knows the rules cold. The exact rules around any individual scenario are something I'd write down and bring to one of our advisors.
And they can look at your actual situation and tell you which doors are still open to you. That's the value. Not just knowing the categories exist, but knowing which one applies to you and when.
For listeners in Arizona and Nevada, the team is at 602-281-3898. And if you want to sit down in person, Ian's piece mentions two workshops coming up on Friday, October 2nd. One at Foothills Library in Glendale at 10:30 in the morning, and one at Mustang Library in Scottsdale at 2:30 in the afternoon. Both at no cost to you. You can register at 123easymedicare.com/medicare-workshop or call 877-220-1089.
And those workshops are educational events presented by that same organization, which is a brand of American Retirement Advisors. They're not affiliated with Medicare or any government agency. Just people who know this stuff sitting down with you to explain it.
The thing I keep coming back to from Ian Schaeffer's piece is that couple. The husband who decided they just wouldn't try Advantage, specifically because he'd looked ahead and thought through what would happen if they ever needed to get out. That kind of forward thinking is hard to do on your own, especially when you're staring at a low premium and everything looks fine. This is exactly why sitting down with someone who asks the uncomfortable questions matters. Not to scare you, but to make sure the choice you make at 65 is one you can actually live with at 70, or 75, or when a diagnosis changes everything. Please don't wait until the window has closed to ask where the door was.
