Which Utah Counties Does Select Health Medicare Cover?

13 of Utah's 29 counties for 2026, and not the 16 you might guess. Here is the county-by-county map of Select Health's five Medicare plans, taken from the CMS landscape file rather than a brochure, what "service area" means when you enroll or move, and the counties where the hospital is Intermountain's but the insurer is not on the shelf.

Here is why this question needs a table rather than a yes or no. Select Health is Intermountain Health's insurance company, and Intermountain's hospitals are in most of Utah, so people assume the Medicare plan follows the hospital. It does not. A Medicare Advantage plan is filed county by county with CMS, and the 2026 file shows Select Health in 13 counties, with different plans reaching different counties. I wrote the Select Health versus UnitedHealthcare comparison in August off the summary counts; this is the plan-level map underneath it, for anyone whose first question is simply "can I get it where I live?"

The five plans and the counties each one reaches

The CMS landscape file lists every approved plan by county. Filtered to Utah and to Select Health, it holds 5 plans under one contract, H1994, spread across 32 county-rows. Premium is the monthly consolidated (Part C plus Part D) premium as filed; the maximum out-of-pocket is the in-network figure; the deductible is the annual Part D drug deductible.

Source: CMS CY2026 Medicare Advantage / Part D Landscape file, September 2026 release, data last updated September 2, 2026; Utah rows for Organization Marketing Name "Select Health." Overall star rating 4.5 on every row. Plan names are as registered with CMS; the dual-eligible plan's premium is the consolidated figure and is generally covered for members who qualify for Extra Help.

Two things stand out. First, the two "Essential" plans are different products with different service areas, deductibles and out-of-pocket limits, even though they share a name: H1994-001 is the Wasatch Front and Cache Valley plan, H1994-017 is the central and southern Utah plan, and the only counties both a Wasatch plan and the southern plan touch are Iron and Washington, through the Kroger plan. Second, the two plans that are not standard drug plans, the D-SNP and the no-drug HMO, reach only the 4-to-6 biggest counties. In Piute, Sanpete, Sevier and Wayne, "Select Health Medicare" means exactly one plan.

County by county: how much of the shelf is Select Health

The table below puts each Select Health county next to its whole 2026 shelf of Medicare Advantage drug plans, from the same CMS file. "Share" is Select Health's drug plans as a percentage of the county's total.

Source: CMS CY2026 Landscape, MA-PD category only (Special Needs Plans, plans without drug coverage and stand-alone drug plans excluded), via CMS CY2026 Medicare Advantage / Part D Landscape. "Also here" lists the dual-eligible D-SNP and the no-drug plan where they are filed.

Read the share column as a description of the county, not a verdict on the carrier. In Salt Lake, Davis, Weber, Utah and Morgan, Select Health is two plans among two dozen from six or seven carriers, and a shopper there is choosing a network first and a logo second. In Wayne County it is the entire Medicare Advantage market: one plan, one carrier, 1 of 1 at a $0 premium, with a $5,700 maximum out-of-pocket. Sanpete and Sevier are two-carrier counties where the alternative is a single national carrier. That is the whole shelf, and the decision there is really Medicare Advantage versus Original Medicare with a supplement, which is a different article: this one.

The 16 counties with no Select Health plan

Beaver, Box Elder, Carbon, Daggett, Duchesne, Emery, Garfield, Grand, Juab, Kane, Millard, Rich, San Juan, Tooele, Uintah and Wasatch. That is more than half the map and, by population, much less than half the state. A few of these are large shelves where the absence is a real gap in the comparison: Tooele (15 plans), Wasatch (13 plans), Box Elder (12 plans), Duchesne (9 plans), Grand (8 plans). Most of the rest are the two-carrier counties of eastern and southern Utah, where the shelf is thin for everyone. Daggett has no Medicare Advantage drug plan from any carrier in the 2026 file.

Grand and San Juan sit in the second group. Moab and Monticello each have 2 carriers, 8 plans in Grand County and 4 in San Juan, and Select Health is in neither. If your cardiologist is at Intermountain Medical Center in Murray or your surgeon at St. George Regional, that is a network question for the plans that are filed in your county, not a reason to look for a plan that is not.

Where the hospital is Intermountain's and the insurer is absent

The assumption I hear most is "Intermountain runs the hospital here, so Select Health must be here." The CMS file says otherwise in three counties. Cross-referencing the CMS Hospital General Information file with the landscape file:

Sources: CMS Hospital General Information (data.cms.gov, updated July 22, 2026), Utah hospitals with "Intermountain" in the registered name; CMS CY2026 Landscape. Some Intermountain facilities are registered under other names, so this is a floor, not the full list.

The lesson runs the other way too. Select Health being in your county tells you nothing about whether your particular clinic is in its network; that is a directory check, plan by plan, which our Utah hospital-networks post walks through. The county is the gate. The network is the room behind it.

What "service area" means when you enroll, and when you move

Medicare.gov lists three conditions for joining a Medicare Advantage plan, and the second is geography: "Live in the service area of the plan you want to join." The service area is the county list above, by permanent residence, which is why a Park City household with a second home in St. George picks a plan by where it is registered to vote and gets mail, not by where it winters; we covered that in the Park City post.

Leaving the service area is the case that catches people. Suppose you retire from Sandy to Moab. Grand County is outside every Select Health service area, so the plan cannot follow you, and Medicare.gov gives you a Special Enrollment Period with a clock: "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." Miss the window and the default is not a different plan. It is no plan: "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." Original Medicare with no drug coverage and no yearly out-of-pocket limit, until you fix it.

Because every Select Health Medicare plan is an HMO, the same geography applies to care while you still live in the service area. Medicare.gov's HMO page limits out-of-network coverage to "Emergency care, Out-of-area urgent care, Temporary out-of-area dialysis," and warns that otherwise "you may have to pay the full cost." A Richfield member on the southern Essential plan who wants a specialist in Salt Lake needs that specialist to be in the plan's directory, or a referral the plan approves; the county line is not the network line, and neither is the Intermountain logo.

What I would do

If you live in one of the 13 counties, treat Select Health as one row on the shelf and run the same three checks on it that you run on the others: your doctors in the 2027 directory by name, your prescriptions on the 2027 formulary by tier, and the maximum out-of-pocket against a bad year. The 4.5-star rating is public and worth noting; it is not a substitute for those checks. If you live in one of the 16 counties, stop looking for it, and make the decision the shelf actually offers, which in Grand and San Juan is two carriers' Advantage plans against Original Medicare with a Medigap policy. And if you are moving in either direction across that line this year, put the move date on the calendar next to October 15 and December 7, because the moving window and Open Enrollment can overlap, and the moving window is the shorter one.

One more local note. In Grand County, 33.3% of adults live with high blood pressure and 11.2% with diabetes; the care for both is mostly primary care and pharmacy, both of which exist in Moab on every plan filed here. The specialty care leaves the county under every plan too. The right question for a Moab reader is not which carrier is missing, but which of the plans that are present covers the trip north.

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 (September 2026 release, data last updated September 2, 2026), filtered to Utah and to Select Health's contract H1994 for every plan, county, premium, maximum out-of-pocket, deductible and star rating stated; the same file, MA-PD category, for each county's total plans and carriers; Select Health's 2026 Utah provider directory (page 2) for the carrier's own county list, quoted as published; Select Health's About page for its parent company; Medicare.gov's joining-a-plan, Special Enrollment Period and HMO pages for the service-area, moving and out-of-network rules, quoted as published; the CMS Hospital General Information file (updated July 22, 2026) for Intermountain-named hospitals; and CDC PLACES county data (2023). Plan facts are the 2026 plan year only; no 2027 plan, premium, county or network is stated, because CMS publishes the 2027 landscape on October 1. No carrier is endorsed or criticized, and a plan's presence or absence in a county is a filing fact, not a judgment. This is education, not advice; confirm plans, costs and eligibility with a licensed agent or Medicare.gov. We take no payment from any carrier to feature a plan.
