Plan discontinued for 2027 · Mesa County, Colorado

Do Married Couples Have to Have the Same Medicare Plan?

No. Medicare is individual coverage, and each of you enrolls, chooses and changes plans alone. That matters most in the fall a plan is discontinued: a Grand Junction couple on the same Medicare Advantage plan gets two letters and owes two answers — and the right answer for one of you may not be the right answer for the other.

Every fall a couple sits down across from me in Grand Junction holding one envelope between them. They have been on the same Medicare Advantage plan for six or eight years, and the letter says the plan will not be offered in Mesa County next year. The first question is almost always the same: "Do we have to stay together?" The answer is that you were never together — not in Medicare's eyes — and this is the year that fact works in your favor. Here is how the program actually treats a married couple, from the regulations, and how I walk two people through one discontinuation.

Medicare has no couples plan

The rules are written for one person at a time. Federal regulation 42 CFR § 422.50 defines eligibility for a Medicare Advantage plan this way: "An individual is eligible to elect an MA plan if he or she meets all of the following: (1) Is entitled to Medicare under Part A and enrolled in Part B." And § 422.66(a) describes how the choice is made: "An individual who wishes to elect an MA plan offered by an MA organization may make or change his or her election during the election periods ... by filing the appropriate election form with the organization." One individual, one election form. When you and your spouse are on "the same plan," you each filed one, and the plan holds two memberships that happen to share a mailbox.

Two things really are household-level. The first is geography: Medicare.gov's joining-a-plan page requires you to "live in the service area of the plan you want to join," so a couple in Fruita shops the same Mesa County menu. The second is the tax return. The Part B premium is billed to each of you — $202.90 a month at the 2026 standard rate per CMS — but the income-related adjustment is calculated from joint modified adjusted gross income: above $218,000 for a joint return (or $109,000 for an individual return), each of you pays the first-tier total of $284.10 instead. That figure is the same whether you are on one plan, two plans, or none; it is decided by the 2024 return, not by anything you choose this fall (our IRMAA explainer covers the tiers).

When the plan is discontinued, you each get a letter — and you each answer it

The non-renewal rule is also written per person. 42 CFR § 422.506 requires a plan that is not renewing its contract to notify "each Medicare enrollee by mail at least 90 calendar days before the date on which the nonrenewal is effective," and to "provide information about alternative enrollment options," including by placing "outbound calls to all affected enrollees." Medicare.gov's description of the Plan Non-Renewal Notice is one sentence long: "You must look for a new plan for coverage next year." If you are both on the plan, that sentence arrives twice. If only one of you is, it arrives once — and the other spouse's plan simply continues.

Sources: 42 CFR § 422.506; Medicare.gov, Plan Non-Renewal Notice; Medicare.gov, Special Enrollment Periods.

The practical consequence is the one couples miss: filing one enrollment does not file two. I have seen a husband enroll himself in a new plan in October, feel finished, and discover in January that his wife — same kitchen, same letter — had defaulted into Original Medicare with no drug coverage because no form went in with her name on it. Medicare.gov's Special Enrollment page states the default plainly for a plan that is leaving: "You'll be enrolled in Original Medicare if you don't join another Medicare Advantage Plan before your current plan ends." That happens to a person, not a household. Our do-nothing post prices that January.

Same plan or different plans: what a comparison actually scores

Once you accept that there are two enrollments, the question becomes whether the same plan is right for both people. It often is. It is also often not, because the things that decide a plan are personal.

Sources: CMS 2026 premiums fact sheet; Medicare Plan Compare (Medicare.gov). The 2027 plans, networks and formularies for Mesa County are published by CMS on October 1; nothing here is a 2027 plan detail.

The doctor row is where it happens most in Grand Junction. One spouse's specialists sit at St. Mary's; the other's primary-care office admits to Community Hospital. In a good year both are in every plan's network, and the couple picks one plan. In the year one carrier's 2027 network is narrower, the couple that insists on one plan ends up with one spouse driving to Montrose or paying out of network. Our network-check post walks through how to verify a 2027 directory by name; do it twice, once per spouse, before you pick anything. The prescription row is the same exercise with the formulary: the spouse taking three maintenance drugs is the one whose list should drive the household's choice, and the other spouse is free to follow — or not.

Mesa County makes this ordinary rather than exotic. CDC PLACES puts high blood pressure at 26.6% of adults and diabetes at 8.1% (2023); in a lot of homes that is one spouse and not the other, and the spouse with the condition has a longer drug list, more specialist visits, and more reason to care about the out-of-pocket maximum. A couple that shops as two people will usually see that in the numbers.

When one of you wants Medigap: the guaranteed-issue window is per person too

A discontinuation is one of the few events that opens a door to Medigap without health questions. Medicare.gov's Medigap tool, for someone whose "Medicare Advantage Plan is leaving Medicare," says you may switch to Original Medicare and apply for a Medigap policy "60 days before the date your coverage ends" and "no more than 63 days after your coverage ends." Colorado's specifics — which plan letters, what the window does and does not cover — are in our Medigap guaranteed-issue post. What matters here is whose right it is. It belongs to the person whose plan ended. If you are both on the plan, you both have it, independently, and one of you can use it while the other picks a new Advantage plan. If only one of you is on the ending plan, only that spouse has the window; the other's route to Medigap runs through their own Medigap Open Enrollment Period, which in Colorado does not come back around.

A household with one spouse on Medigap and one on Advantage is not unusual. It is, in fact, a common shape for a couple where one person has the medical history and the other does not: the spouse with the history takes the no-network, predictable-cost structure while it is available without underwriting, and the spouse in good health keeps a $0-premium Advantage plan (remembering that $0 is the plan premium — the $202.90 Part B premium is still paid "in addition"). Two different structures, two different companies, one address. Nothing in the rules asks you to match.

One money note from Medicare.gov's Medigap cost page: a premium can depend on whether the company "offers discounts (like discounts for women, non-smokers, or married people; discounts for paying yearly; discounts for paying your premiums using electronic funds transfer)." A married-person or household discount can make two policies from the same company cheaper than two from different companies — or not, depending on the company and the plan letter. We quote the household both ways. The policies are still two contracts, each in one name; if one of you later switches, the other's stays.

The calendar, for two people

• By September 30 and October 2: Annual Notices of Change and non-renewal notices are in hand — one per person. Read both, even if they look identical.
• October 15 – December 7 — both of you. Medicare.gov's Open Enrollment is the once-a-year window for anyone to change an Advantage or drug plan. The spouse whose plan continues can still change here; the spouse whose plan ends should. Two comparisons, two enrollments, two confirmation numbers.
• December 8 – last day of February — only the spouse whose plan is leaving. Medicare.gov's Special Enrollment Period for a member of a plan that is ending. It is a safety net, not a plan; a January enrollment leaves a gap in drug coverage for the person who waited, and it gives the continuing spouse no extra rights at all.
• 60 days before to 63 days after December 31 — the Medigap application window for the person whose plan ended.
• January 1. Anyone who filed nothing is in Original Medicare with no drug plan. The other spouse's enrollment does not count for them.

What this looks like at a Grand Junction kitchen table

The couple from the top — same plan for eight years, one letter each. He is 71, sees a cardiologist at St. Mary's, takes four prescriptions, and has had one hospital stay. She is 69, sees a family doctor in Fruita once a year, and takes one generic. We run his comparison first: the 2027 networks that include his cardiologist, the formularies that carry all four drugs on the lowest tiers, the out-of-pocket maximums. His list points hard at one answer, and it might be Original Medicare plus a Medigap policy, using the guaranteed-issue window while it is open. Then we run hers. Her list points at almost everything; she can follow him to Original Medicare and pay a Medigap premium she may not need, or take a $0-premium plan that includes her Fruita doctor and her one drug and carries a dental allowance she will actually use. Some couples pick the same answer for the simplicity. Some pick two. Both are correct, because the rules were never going to grade them as a pair — and both enrollments get filed with two names, two Medicare numbers and two confirmation numbers before December 7.

That is the whole of it. Medicare's rules are individual, the letter is individual, the guaranteed-issue right is individual, and the January 1 default is individual. The one thing a married couple should do together is sit down and make sure two decisions get made.

How we know all this: the Medicare On Main Data Desk frames every article with public data. The individual-eligibility and election language is quoted from 42 CFR §§ 422.50 and 422.66; the 90 calendar days notice to "each Medicare enrollee" and the outbound-call clause from 42 CFR § 422.506; the service-area rule, the Plan Non-Renewal Notice description, the October 15 – December 7 Open Enrollment window, the December 8 – last day of February Special Enrollment Period with its Original Medicare default, the 60 days-before / 63 days-after Medigap application window, and the married-people discount language are quoted from Medicare.gov; the $202.90 Part B premium and the $109,000 / $218,000 thresholds from CMS's fact sheet of November 14, 2025. The household and comparison tables are our framework, not a quote; the couple in the example is an illustration, not a client. Mesa County prevalence is CDC PLACES (2023). No 2027 plan, carrier, premium or network is stated, because CMS publishes the 2027 landscape on October 1. Medicare On Main is a licensed independent insurance agency.
