Which Medicare Advantage Plans Cover St. George, Utah?

Twelve plans, five companies — and the count is the least useful number on the page.

Washington County is the fastest-growing Medicare market in Utah, and the question people type is almost always some version of which plans cover St. George. It has a short factual answer and a long useful one. The short answer is 12 — that is how many Medicare Advantage plans with drug coverage the federal landscape file lists in the county for 2026. The long answer is that the number tells you almost nothing you need, and I would rather spend this page on the part that does.

The 12 plans, and who sells them

For 2026, 5 organizations filed MA-PD plans in Washington County: Aetna Medicare, Humana, Regence BlueCross BlueShield of Utah, Select Health, UnitedHealthcare. Devoted Health and HealthSpring sell in Salt Lake County but not down here — which is the ordinary shape of Utah's market, not a slight against St. George. Of the 12 plans, 7 advertise a $0 monthly plan premium and every one of them tops out at a 4.5 Overall Star Rating.

That last fact deserves a moment. When every plan in your county shares the same highest available star rating, the star column cannot separate them for you. It is a real measure of plan performance, and in a market like this one it is not a tiebreaker.

Why you will see a different number somewhere else

Search this question and you will find counts from the low teens to the high twenties for the same town in the same year. The most common one for St. George is 17. Nobody is being dishonest; they are counting different categories. We count MA-PD only — Advantage plans that include Part D drug coverage — and we say so, because a plan count without a stated denominator cannot be compared to anything. Wider counts add Advantage plans sold without drug coverage, Special Needs Plans you have to qualify for, and sometimes stand-alone drug plans folded in on top.

When you see a number, the useful follow-up is not is that right. It is what did you count.

Southwest Utah, county by county

Here is the part that surprises people. These five counties share a corner of the state, two hospitals of any size, and much of the same referral geography — and their menus do not track their populations at all.

Iron County — Cedar City, about forty-five minutes up I-15 — lists 14 plans to Washington County's 12, from the same 5 companies. Then the floor drops out: Kane, Garfield and Beaver each show 4, from two companies. A retiree in Kanab and a retiree in St. George are two hours apart and looking at completely different markets.

None of that means Cedar City has better coverage than St. George. A plan count is the number of bids insurers chose to file, for reasons that have to do with their networks and their actuaries. If two of Washington County's 12 contract with the doctors you already see, your real menu was always two, and the other ten were never candidates.

The number nobody advertises

Every Medicare Advantage plan must cap what you pay in network for Part A and Part B services in a year. That cap is the plan's honest worst-case number, and it is the one I ask people to look at before the premium.

In Washington County it runs $5,000 to $6,750 — a spread of $1,750. Compare that with Salt Lake County, where the same figure runs $3,500 to $9,250, a $5,750 spread. Southern Utah's plans are clustered tightly, and that changes the advice.

On the Wasatch Front, choosing well on the out-of-pocket maximum can be worth thousands of dollars in a bad year. In St. George, the difference between the most and least protective plan in the county is $1,750 — real money, but not the biggest lever you have. Here, the biggest lever is whether the plan contracts with your people.

The hospital question, and why no list can answer it

The follow-up to which plans cover St. George is almost always does it cover my hospital. I cannot answer that on a page, and neither can anyone else, for a reason worth understanding rather than working around.

A hospital does not accept or refuse Medicare Advantage as a category. Each plan is sold by a private insurer, and that insurer signs a separate contract with each health system, each facility, and often each physician group inside it. Those contracts run on their own schedules and get renegotiated on terms nobody publishes in advance. Medicare.gov's own framing of the consequence is plain enough: with an Advantage plan you may need to use doctors and other providers who are in the plan's network and service area for non-emergency care — and the directory that lists them is a description of a set of contracts, not a promise about them.

So any list of "plans that cover the hospital in St. George," including one I could write today, is a photograph of something that moves. What holds up is a process:

1. Name the doctor and the location, not the system. A plan can contract with a hospital and not with the specialist group practicing inside it. "Is the hospital in network?" can be answered yes and still leave you with a bill.
2. Search the plan's own directory by physician name, for the plan year you are buying. A 2026 lookup does not answer a 2027 question, because networks are set contract year by contract year.
3. Ask the same question twice. The plan's member services line and the clinic's billing office. Directories are known to lag the contracts they describe.
4. Write it down. Date, name, reference number. This is the part people skip and the part that helps them later.

One relief, and it is a real one: Medicare.gov's HMO page lists the exceptions to the in-network rule as emergency care, out-of-area urgent care, and temporary out-of-area dialysis. That is a floor, not a plan — it does not help with the cardiologist you see twice a year.

The four things you can actually buy

The 12 plans are one of four structures, and the structure question comes before the plan question.

Notice that two of the four have no county menu at all. A Medicare Supplement has no network and no service area — any provider in the country who accepts Medicare will take it. In a county where a lot of households keep a second home, or drive to Las Vegas or Salt Lake for specialty care, that is not a small feature.

It is also the option with the tightest door. The one stretch when a company generally must sell you a supplement without health questions is the one-time 6-month window that opens the month you turn 65 and are enrolled in Part B. Utah adds a narrow annual window under state law, with real limits. Outside those, medical underwriting can apply — which means the time to think about this structure is before you need it, not after a diagnosis.

What I would do if I lived in St. George

• Write down your doctors and your prescriptions first. By name and dose, before you open any website. Everything downstream depends on those two lists.
• Settle the structure question before the plan question. Network-and-a-cap, or no-network-and-a-premium. The 12 plans only matter on one side of that fork.
• Price your actual drugs on medicare.gov/plan-compare, against real formularies and preferred pharmacies — not a summary sheet.
• Do not let the plan count or the star column decide anything. Every plan in the county shares the same 4.5 top rating, and the count is a measure of bids filed.
• Verify the hospital and each specialist separately, by name, for the plan year you are buying.
• Re-run all of it next fall. Annual Enrollment is October 15 to December 7, and a plan that fit in 2026 is a brand-new contract in 2027.

How we know all this: the Medicare On Main Data Desk frames every article with public data — here, the CMS CY2026 Medicare Advantage / Part D landscape file, accessed July 2026, for every county figure on this page: Washington County's 12 MA-PD offerings, 7 at $0 plan premium, 5 organizations, 4.5 highest available Overall Star Rating and $5,000–$6,750 in-network out-of-pocket maximum range, plus Iron County's 14, the Beaver, Garfield and Kane figures, the Salt Lake County comparison, and the 280 statewide offerings across 28 counties (178 at $0). We count category MA-PD only and say so, because a plan count without a stated denominator cannot be compared to anything. Medicare.gov supplies the rule that insurers decide whether a plan is sold statewide or only in certain counties, the network-and-service-area rule for non-emergency care, the HMO exceptions for emergency care, out-of-area urgent care and temporary out-of-area dialysis, the yearly out-of-pocket limit, the Annual Enrollment dates and the 6-month Medigap open enrollment rule; CMS's 2026 Parts A & B fact sheet, published November 14, 2025, supplies the $202.90 standard Part B premium and $283 deductible; Medicare.gov supplies the $2,100 out-of-pocket cap and $615 maximum plan deductible for 2026. Hospitals and health systems are referred to as facilities serving this market, not as endorsements, and no network status is asserted for any plan. Carriers are named because their presence in a county is a verifiable fact, not because we recommend any of them. This is education, not advice; confirm your plan, costs, and eligibility with a licensed agent or Medicare.gov. We take no payment from any carrier to feature a plan.
