Rock Springs Medicare 2027: Plan Counts in Sweetwater County

ROCK SPRINGS, Wyo. — If you're sorting through Medicare choices for 2027, it helps to start with a simple question: how many plans can I actually pick from where I live? For people in Rock Springs, the answer is smaller than in a big city — but the options are real, and knowing the lay of the land makes the rest of the decision easier.

Medicare in Rock Springs: What Your 2027 Options Look Like

Rock Springs sits in Sweetwater County, and Medicare plan availability is set at the county level. According to CMS's 2026 Medicare Advantage and Part D Landscape data, Sweetwater County had 3 Medicare Advantage plans available for 2026, offered by 1 carrier. The 2027 lineup is in each plan's ANOC and on Medicare.gov's Plan Finder.

That's the headline for local shoppers. Everything else — Original Medicare, drug coverage, Medigap — is still on the table too.

The Count, in Plain Numbers

Here is what the 2026 landscape looks like for Sweetwater County:

• Medicare Advantage plans available: 3
• Carriers offering Medicare Advantage with drug coverage (MA-PD): 1
• Stand-alone Part D drug plans available: Wyoming has 11 stand-alone Part D plans for 2026, sold statewide
• Contracts rated 4 stars or higher in the area: under CMS's 2026 Star Ratings, none of the 1 Medicare Advantage contracts offering plans in Sweetwater County has a 2026 Star Rating assigned
• Residents 65 and older in Sweetwater County: about 6,131

A few notes on what these numbers mean — and don't mean.

Star Ratings are CMS's way of measuring plan quality (customer service, care coordination, member complaints, and more). A rating below 4 stars doesn't mean a plan is bad; it means CMS scored it lower on those specific measures. Ratings can change year to year.

On drug coverage, Wyoming has 11 stand-alone Part D plans for 2026, sold statewide. In practice, Wyoming retirees have Part D options available through the statewide stand-alone drug plan market — you'll see those when you run your ZIP code through the Medicare Plan Finder at medicare.gov.

Why the Count Is Smaller Here

Rural counties across the Mountain West often have fewer Medicare Advantage plans than metro areas. Insurers build plans around networks of doctors and hospitals, and thinner provider networks mean fewer plans. That's not unique to Sweetwater County — it's the pattern across much of Wyoming.

The upside: fewer plans can mean less overwhelm at decision time. The tradeoff: you may want to look carefully at whether your doctors, the Memorial Hospital of Sweetwater County, and your prescriptions are covered under any plan you're considering.

If Medicare Advantage doesn't fit, remember Original Medicare (Parts A and B) is always available, and you can pair it with a stand-alone Part D drug plan and, if you choose, a Medigap policy.

What's New for Everyone in 2027

A few program-wide changes matter no matter which direction you go:

• Part D out-of-pocket cap: $2,100 in 2026 and $2,400 in 2027. Once your drug spending hits that ceiling, you pay nothing for covered drugs the rest of the year.
• Part D deductible: up to $615 in 2026 ($700 in 2027), depending on the plan.
• The coverage gap ("donut hole") is gone. As of 2025, Part D has three phases instead of four.
• Medicare Prescription Payment Plan: an optional program that lets you spread drug costs across monthly payments instead of paying big amounts at the pharmacy counter.
• IRMAA: higher-income beneficiaries pay a surcharge on Part B and Part D premiums, starting above $109,000 in income for a single filer in 2026.

Key Dates to Circle

• Annual Enrollment Period: October 15 – December 7, 2026. This is when you can join, switch, or drop a Medicare Advantage or Part D plan for 2027.
• Medicare Advantage Open Enrollment: January 1 – March 31. If you're already in a Medicare Advantage plan, you get one chance during this window to switch to another MA plan or return to Original Medicare.

Missing these dates usually means waiting a full year, so put them on the fridge calendar.

How to Compare Your Actual Choices

Because we can't discuss specific plan benefits here, the best move is to run the numbers yourself against your own doctors, prescriptions, and budget:

1. Go to medicare.gov/plan-compare and enter your Rock Springs ZIP code. 2. Add your prescriptions and preferred pharmacies. 3. Add your doctors, so you can see which plans include them. 4. Compare total estimated yearly cost — not just the premium.
