Is the AI you gave up on the same AI everyone is talking about now?

It did. And I think what got me is how many people are walking around with a plan they genuinely like, a plan that works great for them nine months out of the year, and they have no idea there are two rules sitting inside that plan that could take it away if they stay gone too long.

Three callers, three completely different situations. And the whole point Ian is making is that those three situations have three different answers, and the thing that separates them is where the county line falls.

So the plans are built around a service area, and that service area is defined at the county level. The rules are clear about this: to join a plan, one of the requirements is that you live in the plan's service area. Not the state, the service area. And the plan can disenroll you if you move outside it. So if you have a plan that covers Maricopa County in Arizona and you go spend six months in Connecticut, your plan is doing a daily calculation about whether you still belong on its books.

For 2026, KFF counts an average of 32 Medicare Advantage plans with drug coverage per beneficiary nationally. But people in urban counties can choose from about 42 plans, and people in the most rural counties are looking at around 20. So the county you live in doesn't just determine whether your plan covers you, it determines how many options you even had to begin with.

That's exactly the picture Ian paints. And he also notes that Arizona has 133 Advantage plans available for 2026, Nevada has 105. So even between neighboring states the picture looks different. This is not a uniform national product. It is deeply local.

Most don't. And Ian actually quotes the federal regulation directly, which I appreciate, because this isn't him interpreting something, this is the rule as written. Under 42 CFR 422.74, the regulation says that if you have not moved from your plan's service area but you have left it for more than six months, the plan must disenroll you. Must. He puts that word in bold and I think he's right to.

It really is. Because people hear that their plan dropped them and they feel like something unfair happened. But Ian makes the point that the plan isn't being unkind. It is following the law. The section this sits under is literally called Required Disenrollment. The plan has no choice after six months.

So the regulation also says that a member is considered to be temporarily absent from the service area when required plan mail is returned to the plan as undeliverable and a forwarding address hasn't been provided. Meaning if your plan sends you something to your home address while you're in Connecticut and the post office returns it because there's no forwarding on file, that can start the clock on your absence. So Ian's advice is really practical: keep your forwarding address current, and tell the plan your seasonal address.

Exactly. And the fix is so simple. It's just a phone call or a letter to the plan before you leave. Which is a theme throughout this whole piece, by the way. So much of this is easier if you do it before you leave, not after something goes wrong.

You're right to be careful. The regulation does allow plans to offer what it calls a visitor or traveler benefit, where the plan may elect to let you stay enrolled for an absence longer than six months but less than twelve, at the same cost sharing you'd have at home. But there are three things Ian flags that are really important. First, the word is may elect. It's the plan's choice. Many plans don't offer it at all. Second, even plans that offer it can limit which geographic areas qualify. And third, even with the benefit, you are disenrolled on the first day of the thirteenth month after you left. So twelve months is the absolute ceiling, no exceptions.

And that ceiling is the ceiling -- sorry, no em dashes -- let me try again. And that's as far as it goes. The only way to know whether your specific plan offers it is to ask. Ian says to ask in writing, before you leave. Not when you're already in Connecticut in August wondering why you got a letter.

They do, and the regulation actually uses both words, which Ian highlights. It says has not moved from the service area, but has left. Those are legally two different situations. The person who goes to Connecticut for seven months and still has their Arizona address, still thinks of Arizona as home, that person gets dropped under the six-month rule. The person who actually changes their permanent address to Massachusetts, that person gets a Special Enrollment Period.

So Medicare says your chance to switch begins when you move and continues for two full months after you move. But here's the part that's worth knowing: if you tell your plan before you move, that window opens a month earlier. It starts the month before you move and still runs two full months after. So telling the plan first buys you an extra month. Ian frames it as at no cost to you, and he's right, it just requires a phone call.

You get enrolled in Original Medicare when the old Advantage plan drops you. Which isn't necessarily a disaster, but you're also without a drug plan at that point, and you haven't made any of these decisions intentionally. You've just defaulted into an outcome.

And then there's the second door that opens when someone actually moves. Ian calls it the 63-day window, and it ties back to something from earlier in this series. Moving out of a plan's service area gives you a guaranteed-issue right for a Medicare Supplement, meaning you can get a Supplement without medical underwriting. But the deadline is no more than 63 days after your Medicare Advantage coverage ends. Not 63 days after the moving truck showed up. After coverage ends.

It really is. And there's one more condition: the guaranteed-issue right only applies if you switch to Original Medicare rather than just joining another Advantage plan. If you move and immediately pick a new Advantage plan in the new state, you don't trigger that Supplement right. So the order of decisions matters.

This depends almost entirely on whether your plan is an HMO or a PPO. And Ian lays it out really simply. If you're in an HMO, Medicare says you generally have to get your care from providers in the plan's network. The exceptions are emergency care, out-of-area urgent care, and temporary out-of-area dialysis. Everything else, you may have to pay the full cost.

Full cost. And urgent care has a specific definition here. Medicare defines it as a sudden illness or injury that's not a medical emergency and not life threatening. So Ian makes the point that a refill appointment is not urgent care. A follow-up for your knee is not urgent care. Those are routine visits, and in an HMO out of network, you're paying the whole thing.

Friendlier sentence from Medicare on that one. You can generally go to out-of-network providers for covered services, but you'll pay more. So it's covered, just at a higher cost share. Which is still not ideal, but it's a very different situation from full cost.

That's what Ian says. HMO or PPO is the first question. And it's the kind of question people often don't know off the top of their heads, even when they've had the plan for years.

Usually, yes. Pull it out.

Ian addresses this directly. Original Medicare doesn't have that boundary problem at all. He quotes Medicare directly: you can use any doctor or hospital that takes Medicare anywhere in the U.S., and Medicare defines that as all 50 states, the District of Columbia, and five territories. If you have a Medigap Supplement riding alongside Original Medicare, it travels with you. Medicare says you can keep your Medigap policy no matter where you live, as long as you still have Original Medicare.

The policy travels. Now if you change your permanent address to the other state, your premium may adjust because it's priced partly by where you live. And if you want to switch companies after a move, you may have to answer medical questions. But the policy itself, the coverage, follows you. For a family doing two states every year, Ian says that's a structural difference worth putting on the table.

That's the whole point of what Ian describes a Certified Medicare Planner doing. They run the whole year, both houses, before anyone picks. Not just the premium in Scottsdale.

Part D sits in the middle. It's sold by region, not by county. Ian says there are 34 regions nationally and a drug plan has to serve at least an entire Part D region. Arizona had 10 stand-alone drug plans for 2026, Nevada also had 10. So there's more geographic flexibility than Advantage, but you still want to check whether your plan's pharmacy network in the other state is going to work for you, because as Ian notes, the answer there can affect your copay.

For maintenance medications especially, shipped to whichever porch you're currently standing on. It's not a perfect solution for everything, but it removes a lot of the pharmacy network geography problem.

He does, briefly, because he knows some snowbirds head south past the border, not just to another state. The short version: Original Medicare generally doesn't cover medical care outside the U.S. And Advantage plans generally don't either. So someone who winters in Mexico, or travels internationally, that's a separate conversation. Ian notes that some Supplements have a foreign travel emergency benefit, capped and time limited, and says that conversation belongs in a different discussion. He's not opening that whole thing in this piece, and neither should we.

They start with both addresses and the dates before they ever ask about benefits. That's the foundation. Then they read which sentence the plan lives under, HMO or PPO, and they tell you what a routine visit in the other state is actually going to cost. They ask the plan in writing whether it offers a visitor or traveler benefit and for how long. And they put the six-month date on the calendar the day you leave.

It's a real date. If you leave May 1st, the six-month clock is real and it runs. Knowing that date means you can plan around it rather than discover you've crossed it.

Because it buys that extra month on the Special Enrollment Period window. And they start the 63-day Supplement clock from the right day, which is when coverage ends, not when the move happened. Getting that date wrong can cost someone their guaranteed-issue right.

And it's the kind of thing where I'd want someone who does this every day to put the date on my calendar, not try to track it myself in the middle of a move.

Right. We can describe the shape of the rule, but they're the ones who can look at your actual plan, your actual dates, and tell you what applies to you.

And the plan isn't going to call you. The county line isn't going to send you a reminder. The six-month rule isn't something that shows up in your welcome kit in big letters. You have to go looking for it, or talk to someone who already knows where it is.

And he ends with an invitation, which I appreciate. If there's a corner of it that has ever confused you, let them know, and it may be the next one they take apart. They're at 602-281-3898.

In-person is a different kind of conversation. You can ask about your specific schedule, your specific plan, your specific two addresses. That's hard to do anywhere else.
