Moving and Medicare in 2026: the Special Enrollment Period that follows you to Ouray County
Original Medicare and a Medigap policy travel with you anywhere in the country. A Medicare Advantage plan does not — it stops at a county line. Here's exactly what a change of address does to your coverage, and the two-month clock it starts.
The bottom line
- A move gives you a Special Enrollment Period for Part C and Part D only. It is not a way to sign up for Part A or Part B.
- The clock is two full months after the move — but if you tell your plan before you go, it starts the month before the month you move.
- Original Medicare and Medigap move with you. Medicare.gov: you can keep your Medigap policy no matter where you live, as long as you still have Original Medicare.
- Medicare Advantage doesn't. Move out of the service area, do nothing, and you're dropped into Original Medicare — possibly with no drug plan and a 63-day penalty clock running.
- The overlooked right: moving out of an Advantage plan's service area gives you a guaranteed issue right to buy Medigap — but only if you go back to Original Medicare instead of joining another Advantage plan.
- Local context: 27.6% of Ouray County's Medicare beneficiaries were in a Medicare Advantage or other health plan in 2025, versus 47.3% in Delta County. Cross a county line here and the plan market changes underneath you.
The short answer
When you change your address, Medicare gives you a Special Enrollment Period to switch your Medicare Advantage plan or your Medicare drug plan. It begins when you move and continues for 2 full months after you move — or, if you tell your plan before you move, it begins the month before the month you move and still runs 2 full months past it. Original Medicare and a Medigap policy are not affected by a move at all: you keep them wherever you live. A Medicare Advantage plan is, because it's sold with a service area, and if you move out of that area and don't pick a new plan in time, Medicare puts you back in Original Medicare — with no drug coverage unless you arrange it.
That's the whole rule. What follows is the timing in detail, the Medigap rights a move creates, the drug-coverage gap that costs people money afterward, and the numbers behind how different the plan market is from one Western Slope county to the next. Every figure links to Medicare.gov, CMS, the Colorado Division of Insurance, or Social Security. This is education, not advice.

What travels with you, and what stops at the county line
Almost every moving question resolves once you know which of two categories your coverage falls into.
National coverage — moves with you. Original Medicare (Part A and Part B) works with any doctor or hospital that takes Medicare, anywhere in the United States. A Medigap policy sits on top of it, and Medicare.gov's answer for someone moving out of state is unambiguous: you can keep your current Medigap policy no matter where you live, as long as you still have Original Medicare. Your premium is set by the policy you bought, not the county you sleep in.
Local coverage — stops at a boundary. A Medicare Advantage plan is a contract between a private company and Medicare to serve a defined area, built from counties and ZIP codes. Its network of doctors, its premium, its out-of-pocket maximum, and its extra benefits are all specific to that area. Take that plan somewhere it isn't sold and it simply doesn't follow.
Regional coverage — usually survives a move within Colorado. Stand-alone Medicare drug plans sit in between. CMS organizes them into prescription drug plan regions rather than counties, and Colorado is a single region on the CMS map. A move from Montrose to Ridgway generally keeps you inside your drug plan's footprint. Even so, Medicare.gov grants the Special Enrollment Period in both directions — for a move outside the service area and for a move that stays inside it but gives you new plan options — so you're not locked in either way.
Here in Ouray County that distinction is not academic. The nearest hospital, most specialists, and most pharmacies for people in Ouray and Ridgway are down valley in Montrose or over in Grand Junction, and plenty of households move between those places in retirement — down valley for winter access and services, up valley for the quiet. Each of those moves crosses a county line, and for a Medicare Advantage member each one starts a clock.

Every move-related Special Enrollment Period, and its exact timing
Medicare treats five different life changes as "you changed where you live." Each has its own window. These are the published federal rules for 2026, drawn from Medicare.gov's Special Enrollment Periods page and the CMS enrollment-periods fact sheet:
| If you… | You can… | When |
|---|---|---|
| You move to a new address that isn't in your plan's service area | Switch to a new Medicare Advantage Plan (with or without drug coverage) or a Medicare drug plan. You can also choose to go back to Original Medicare if you're in a Medicare Advantage Plan and you move outside its service area. | Your chance to switch begins when you move and continues for 2 full months after you move. If you tell your plan before you move, it begins the month before the month you move and continues for 2 full months after. |
| You move to a new address still inside your plan's service area, but you have new plan options in the new location | Switch to a new Medicare Advantage Plan (with or without drug coverage) or a Medicare drug plan. | Same timing: it begins when you move and continues for 2 full months after — or the month before the move, if you tell your plan first. |
| You move back to the U.S. after living outside the country | Join a Medicare Advantage Plan or a Medicare drug plan. | Your chance to join lasts for 2 full months after the month you move back to the U.S. |
| You live in, or recently moved out of, an institution such as a nursing home or rehabilitation hospital | Join, switch, or drop a Medicare Advantage Plan or Medicare drug plan, or return to Original Medicare. | It lasts as long as you live in the institution, and for 2 full months after the month you move out. |
| You were incarcerated and have been released | Join a Medicare Advantage Plan or a Medicare drug plan. You must have Part A and/or Part B first. | 2 full calendar months after you're released. If you lost Medicare while incarcerated, contact Social Security — a separate Part A/Part B Special Enrollment Period may apply. |

Two details in that table do more work than they look like they should. The first is the phrase "2 full months." It doesn't mean sixty days from the moving truck. If you move on March 20, the two full months are April and May, and your window closes May 31. The second is that the institutional Special Enrollment Period is open-ended: someone living in a nursing home or rehabilitation hospital can join, switch, or drop a plan the entire time they live there, plus two full months after moving out. That is a genuinely different rule from everyone else's, and it matters for families placing a parent in care in Montrose or Grand Junction.
Why telling your plan first is worth a month
Medicare gives you a better window if you notify your plan before the move rather than after. Compare the two:
- You tell your plan first. Your chance to switch begins the month before the month you move and continues for 2 full months after you move.
- You don't. Your chance to switch begins when you move and continues for 2 full months after you move.
The extra month is the smaller benefit. The bigger one is sequencing. Enrolling before the move lets you set your new coverage to begin the first of the month your old plan ends, so there's no stretch where you've left the old network and haven't joined a new one. Do it the other way around and you can spend weeks technically enrolled in a plan whose doctors are ninety miles behind you.
There's no special form for this. Call the member services number on your plan card, tell them your moving date and your new address, and write down who you spoke with and when. If you're already working with a licensed agent, that call is one they can make with you.

How different the plan market is county to county
The reason a move matters so much on the Western Slope is that the six counties this agency serves have strikingly different coverage mixes. CMS publishes county-level enrollment, and the calendar year 2025 figures show the split:
Source: CMS — Medicare Monthly Enrollment (data.cms.gov) — calendar year 2025 annual figures by county of residence. Bars show beneficiaries in the CMS "Medicare Advantage and other health plan" category as a share of all Medicare beneficiaries in the county; the remainder are in Original Medicare. Retrieved August 2026.
Read that chart as a map of what a move does to you. In Delta County, nearly half of all beneficiaries (47.3%) are in a Medicare Advantage or other health plan — so for the average Delta County resident, a move is very likely to be a coverage event. In Pitkin County, only 11.8% are, and the typical Aspen-area beneficiary has Original Medicare, which travels.
Ouray County sits in between, and it's a small population with a specific shape. CMS counted 1,694 Medicare beneficiaries in the county in 2025: 1,227 in Original Medicare and 467 in a Medicare Advantage or other health plan. Separately, 923 had a stand-alone Medicare drug plan — the Part D coverage that pairs with Original Medicare.
Sources: CMS — Medicare Monthly Enrollment (data.cms.gov) · Medicare.gov — Special Enrollment Periods · CMS — Medicare Open Enrollment in Colorado, 2026 (state-by-state fact sheet, September 26, 2025).
One caution on reading county-level numbers: they describe where people live, not what's for sale at your address. Medicare Advantage service areas are drawn by ZIP code and change from year to year. A county figure tells you the shape of the market; only Medicare.gov Plan Compare — or a licensed agent running your specific new address — tells you what you can actually buy there.
Moving with a Medigap policy
If you have Original Medicare and a Medicare Supplement policy, the honest answer is that a move usually changes nothing. Medicare.gov's guidance for someone moving out of state: you don't have to switch, but you might be able to, if you want. You can keep your current Medigap policy no matter where you live, as long as you still have Original Medicare.
Three situations are exceptions worth knowing:
- You have a Medicare SELECT policy. Medicare SELECT is a Medigap policy that requires you to use specific hospitals and, in some cases, specific doctors — so it does have a service area. Move out of it and you have a guaranteed issue right to buy Medigap Plan A, B, C, D, F, or G sold by an insurance company in your state or the state you're moving to. You must apply either up to 60 days before your Medicare SELECT coverage ends or no more than 63 days after it ends. If you've had the SELECT policy more than 6 months, Medicare.gov notes you won't have to answer medical questions.
- You want to switch policies while you're at it. Outside your one-time 6-month Medigap Open Enrollment Period, you can generally only change policies when a guaranteed issue right applies. A move by itself isn't one — for someone already on Original Medicare with a Medigap plan, wanting a cheaper policy in a new town means medical underwriting, and the Colorado Division of Insurance warns that buying a Medigap outside an open enrollment period lets companies decline to cover pre-existing conditions for a period of months.
- You're leaving a Medicare Advantage plan because of the move. That's the big one, and it gets its own section below.
A note specific to this state: Colorado does not have an annual "birthday rule" or other standing window that lets you swap Medigap policies without underwriting. The Division of Insurance's own Medigap guide lists the federal guaranteed issue situations and the 6-month window after you enroll in Part B, and that's the menu.

Book an appointmentThe guaranteed issue right people forfeit by accident
This is the single most valuable thing in this article, and it's buried in a table on page 17 of the official CMS Medigap guide.
If you're in a Medicare Advantage plan and you move out of the plan's service area, you have a guaranteed issue right to buy a Medigap policy. In plain terms, that means an insurance company must sell you one of the listed policies, must cover all of your pre-existing conditions, and can't charge you more because of your health history. The Colorado Division of Insurance lists the same right in its state Medigap guide.
Now the condition, quoted from the CMS guide: "You only have this right if you switch to Original Medicare (rather than join another Medicare Advantage Plan)."
Read that twice, because it's a fork in the road with no sign on it. Someone moving from Montrose to Ridgway, or from Ridgway to Grand Junction, gets a Special Enrollment Period and a menu of local Advantage plans. Choosing one of them is a perfectly reasonable decision — and it closes the door on a health-history-free Medigap purchase that was open for exactly that window.
The mechanics if you do use it:
- What you can buy: Medigap Plan A, B, C, D, F, or G sold by an insurance company in your state. Plans C and F are no longer available to people new to Medicare on or after January 1, 2020 — if that's you, the equivalents are Plan D and Plan G.
- When to apply: up to 60 days before the date your Medicare Advantage coverage ends, or no more than 63 days after it ends. The CMS guide also notes that a Medigap policy can't start until your Medicare Advantage coverage ends.
- What to keep: copies of every letter, notice, email, or claim denial with your name on it, plus the postmarked envelope. You may need to attach them to the Medigap application as proof you have the right.
Two adjacent rights are worth knowing in the same breath, because a move is often when people reconsider a decision they made a year earlier. If you joined a Medicare Advantage plan when you were first eligible for Medicare at 65 and you're still within your first 12 months, you have a trial right to switch to Original Medicare and buy any Medigap policy sold in your state. And if you dropped a Medigap policy to try Medicare Advantage for the first time and you've been in it less than a year, you have the right to buy that same policy back if the company still sells it.

The drug-coverage trap after a move
Here's the sequence that costs people money, and it starts with doing nothing.
Medicare.gov states it plainly: if you move outside your old plan's service area and don't join a new Medicare Advantage Plan during this Special Enrollment Period, you'll be enrolled in Original Medicare when you're dropped from your old Medicare Advantage Plan.
Your hospital and medical coverage is fine — Part A and Part B continue, at the standard $202.90 monthly Part B premium and $283 annual deductible for 2026. What's gone is the drug coverage that was bundled into the Advantage plan. Original Medicare doesn't include Part D. Nobody enrolls you in a drug plan automatically.
And the meter starts running. Medicare's late enrollment penalty applies when you go 63 days or more in a row without Medicare drug coverage or other creditable drug coverage after your Initial Enrollment Period is over. The penalty is calculated as 1% of the national base beneficiary premium — $38.99 in 2026 — multiplied by the number of full months you went without, rounded to the nearest 10 cents and added to your monthly Part D premium. In most cases you keep paying it for as long as you have Medicare drug coverage.
Two full months is a short window when you're also unpacking boxes and finding a new primary care doctor. Set a reminder for the 15th of the first month after you move.

What a move does not get you
It's as important to know the limits of this Special Enrollment Period as its reach.
- It is not a way to enroll in Part A or Part B. Medicare.gov's moving Special Enrollment Periods are about changes to Medicare Advantage and Medicare drug coverage. If you delayed Part B and now regret it, moving doesn't fix that — the Part A and Part B Special Enrollment Periods are a separate set of rules administered by Social Security, tied to circumstances like losing employer coverage or an exceptional condition. We cover the delay-and-penalty math in our Part B late enrollment penalty guide.
- It doesn't erase a penalty you already owe. A Part B or Part D late enrollment penalty follows you across state lines like everything else in Original Medicare.
- It doesn't extend the Annual Enrollment Period. AEP still runs October 15 through December 7 for everyone. A moving Special Enrollment Period is in addition to it, not instead of it — and if you move in, say, October, you may briefly hold both, which simply means more time and more options, not fewer.
- It doesn't guarantee your doctor comes with you. A new plan means a new network. Confirm your providers accept the specific plan before you enroll, not after.

Colorado's 2026 plan landscape
Whatever you had in your old county, it's worth knowing what the statewide market looks like before you shop, because it changed this year.
CMS's Colorado fact sheet for 2026 reports 1,056,627 people enrolled in Medicare statewide. For 2026, 108 Medicare Advantage plans are available in Colorado, compared with 132 plans in 2025 — a meaningful contraction. The average monthly Medicare Advantage plan premium moved from $11.41 in 2025 to $12.91 in 2026, 97.1% of people with Medicare in Colorado have access to a Medicare Advantage plan with a $0 monthly plan premium, and 10 stand-alone Medicare drug plans are available statewide.
A $0 monthly plan premium is not the same thing as free coverage — you still pay your Part B premium ($202.90 standard in 2026), and the plan still has copays, coinsurance, and an out-of-pocket maximum. It only means the plan itself adds no premium on top.
The practical implication of a shrinking plan count is that a plan you liked in one county may not have a counterpart in the next one. Don't assume continuity — check.

A moving checklist, in order
- Before you move, call your plan. Give them your moving date and new address. This starts your Special Enrollment Period the month before the move instead of the month of it.
- Update your address with Social Security. If you get Social Security benefits or are enrolled in Medicare, you can change your U.S. mailing address online through your my Social Security account, or by calling 1-800-772-1213.
- Look up your new ZIP code on Medicare.gov Plan Compare. Service areas are drawn by ZIP, not county. Do this before you cancel anything.
- Decide the Original Medicare question deliberately. If you're leaving an Advantage plan because of the move, that's your window for a guaranteed issue Medigap purchase — and it closes the moment you enroll in another Advantage plan instead.
- If you're going back to Original Medicare, line up a drug plan in the same breath. Nothing enrolls you automatically, and the 63-day penalty clock doesn't wait for you to settle in.
- Check your prescriptions against the new plan's formulary and confirm a pharmacy near your new address is in network. In small mountain towns that's a shorter list than you'd think.
- Confirm your new doctors take the plan — call the clinic, not just the plan's directory.
- Keep every letter. Notices, emails, and claim denials are the proof of a guaranteed issue right, and applications get denied for lack of documentation more often than for health reasons.
- Note your deadline in writing. Two full months after the month of the move, not sixty days.
- Get a free second opinion. Colorado's State Health Insurance Assistance Program, run through the Division of Insurance, offers one-on-one counseling at no cost and sells nothing.

Moving with Medicare, answered
How long do I have to change my Medicare plan after I move?
Medicare.gov states that your chance to switch begins when you move and continues for 2 full months after you move. If you tell your plan before you move, your chance to switch plans begins the month before the month you move and continues for 2 full months after you move. That earlier start is worth using: telling your plan first can give you an extra month and, more importantly, it lets you line up new coverage so it starts the day your old plan ends instead of leaving a gap. The same window applies whether your new address is outside your plan's service area or still inside it with new plan options available. This Special Enrollment Period is for Medicare Advantage and Medicare drug plans only — it is not a way to sign up for Part A or Part B.
Do I have to change plans if I move within Colorado?
It depends entirely on what kind of coverage you have. If you have Original Medicare — Part A and Part B — nothing changes when you move. Medicare.gov's guidance on Medigap is equally direct: you can keep your current Medigap policy no matter where you live, as long as you still have Original Medicare. Medicare Advantage is the opposite. Those plans are sold with defined service areas, and CMS's own county-level enrollment data shows how differently they're taken up across our region: in calendar year 2025, 47.3% of Delta County's Medicare beneficiaries were in a Medicare Advantage or other health plan, compared with 27.6% in Ouray County and 11.8% in Pitkin County. A move of thirty miles can put you in a completely different plan market. Stand-alone drug plans work on a broader footprint — CMS organizes them into prescription drug plan regions rather than counties — so a move within Colorado generally keeps you inside your drug plan's region.
If I move out of my Medicare Advantage plan's service area, can I buy a Medigap policy without medical underwriting?
Yes, in that specific situation federal law gives you a guaranteed issue right — but it comes with a condition most people miss. The official CMS guide Choosing a Medigap Policy lists "you move out of the plan's service area" among the guaranteed issue situations for someone in a Medicare Advantage Plan, and then adds this: you only have this right if you switch to Original Medicare, rather than joining another Medicare Advantage Plan. Take the second Advantage plan and the Medigap right goes away. When the right does apply, you can buy Medigap Plan A, B, C, D, F, or G sold by an insurance company in your state — Plans C and F only if you were eligible for Medicare before January 1, 2020 — and you must apply either up to 60 days before your Medicare Advantage coverage ends or no more than 63 days after it ends. Medigap policies can't start until the Advantage coverage ends. The Colorado Division of Insurance lists the same right in its own Medigap guide.
Does moving give me a Special Enrollment Period to sign up for Part B?
No. The moving Special Enrollment Periods on Medicare.gov are explicitly about making changes to your Medicare Advantage and Medicare drug coverage. Moving to a new address — even across the country — does not by itself create a chance to enroll in Part A or Part B outside your normal enrollment periods, and it does not erase a Part B late enrollment penalty you already owe. The Part A and Part B Special Enrollment Periods are a separate set of rules tied to things like losing employer coverage, an exceptional condition such as a disaster or emergency, losing Medicaid, or release from incarceration, and Social Security handles those. If you're moving and you don't yet have Part B, treat that as its own question and call Social Security before you assume the move helps.
What happens if I do nothing after I move out of my plan's area?
You get dropped, and where you land depends on what you had. Medicare.gov states that if you move outside your old plan's service area and don't join a new Medicare Advantage Plan during this Special Enrollment Period, you'll be enrolled in Original Medicare when you're dropped from your old Medicare Advantage Plan. Your Part A and Part B coverage continues, so you are not uninsured — but if your old plan included drug coverage, you may now have none. That's the expensive part. Medicare's late enrollment penalty applies when you go 63 or more days in a row without Medicare drug coverage or other creditable drug coverage after your Initial Enrollment Period ends. The penalty is 1% of the national base beneficiary premium — $38.99 in 2026 — for every full month you went without, it's added to your Part D premium, and in most cases you keep paying it for as long as you have Medicare drug coverage.
What should I do first when I know I'm moving?
Tell your plan before you move, not after. That single step starts your Special Enrollment Period the month before your move instead of the month of it, which gives you room to pick new coverage that begins the day the old one ends. Then update your address with Social Security, since that's the address Medicare uses. Then check your new address on Medicare.gov Plan Compare rather than assuming a county-level plan list applies to you — Medicare Advantage service areas are drawn by ZIP code and change from year to year. If you have Original Medicare with a Medigap policy and you're staying in Original Medicare, there is usually nothing to change at all. Colorado's State Health Insurance Assistance Program offers free, unbiased one-on-one counseling and sells nothing, and it's a good second opinion before you cancel anything.
