St. George is where Utah retires, and its Medicare market has grown with it: a moderate Advantage menu built around Intermountain St. George Regional, and Nevada twenty minutes away.
What to know before you compare plans in Washington County
Washington County offers a moderate Advantage menu, every Medigap carrier in Utah and the full Part D lineup. Intermountain St. George Regional handles most local care; specialty care means Salt Lake or Las Vegas, and many residents see doctors in Mesquite, which an Advantage network may not include.
Because St. George households winter locally, travel to Nevada and Arizona, and retire here from the Wasatch Front, we compare Advantage against a Medigap policy with the map in front of us.

Your options
Which kind of plan fits you in St. George?
Medicare Advantage
All-in-one Part C plans, often $0 premium, that use a network — usually built around Intermountain, the U, MountainStar or Holy Cross.
Medigap pairs with Original Medicare and lets you see any provider nationwide that accepts Medicare — Huntsman, Intermountain, or a clinic in Mesquite.
Washington County typically offers a moderate Medicare Advantage menu built around Intermountain St. George Regional, every Medigap carrier in Utah, and the full Part D lineup. Availability changes each plan year.
Can I see a doctor in Mesquite or Las Vegas with a St. George plan?
With Original Medicare and a Medigap policy, yes. With a Medicare Advantage plan, only if the Nevada provider is in-network, which we confirm before you enroll.
How much does your help cost?
Nothing. Independent agents are paid by the carriers when you enroll, so comparing plans and reviewing your coverage each year is free to you.
