Rapid City Medicare 2027: Options in Pennington County

RAPID CITY, S.D. — If you're turning 65 soon or already on Medicare, you probably want a simple picture of what's available where you live. Rapid City sits in Pennington County, and that county line is what actually determines which Medicare plans you can join. Here's a plain-English snapshot as you look at 2027 coverage, plus the program rules that apply no matter which plan you pick.

A Rapid City Look at Medicare for 2027

What's Available in Pennington County

Medicare Advantage and Part D plans are approved at the county level, so availability in Rapid City mirrors Pennington County. For 2026, the county has:

• 12 Medicare Advantage plans to choose from
• 4 carriers offering Medicare Advantage with prescription drug coverage (MA-PD)
• 11 stand-alone Part D plans available statewide in South Dakota for 2026, sold statewide
• 1 contract rated 4 stars or higher under CMS's 2026 Star Ratings

About 22,870 people age 65 and up live in Pennington County, so you're far from alone in sorting through these choices.

A quick note on star ratings: Medicare rates plans from 1 to 5 stars based on member experience, customer service, and quality measures. Ratings can shift year to year, and they're one signal among many — not a reason on their own to pick or skip a plan.

The Rules That Apply to Everyone

No matter which plan you choose, these program-level facts apply nationwide. Where a 2027 figure isn't published yet, the 2026 number is labelled as such:

• 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 maximum deductible: $615 in 2026 and $700 in 2027. Plans can charge less, but not more.
• No more donut hole. As of 2025, Part D moved to three phases: deductible, initial coverage, and catastrophic. That structure continues in 2027.
• Medicare Prescription Payment Plan. This optional program lets you spread your drug costs into monthly payments instead of paying big bills at the pharmacy counter.
• IRMAA surcharges on Part B and Part D start above $109,000 in income for a single filer in 2026 (higher for joint filers).

Dates to Circle

Two enrollment windows matter most:

• Annual Enrollment Period: Oct. 15 – Dec. 7. This is when anyone with Medicare can join, switch, or drop a Medicare Advantage or Part D plan for the following year.
• Medicare Advantage Open Enrollment: Jan. 1 – March 31. If you're already in a Medicare Advantage plan, you get one chance during this window to switch to a different MA plan or return to Original Medicare.

Missing these dates usually means waiting a full year, so mark your calendar.

How to Decide What Fits You

There's no single "right" plan — the best fit depends on your doctors, your prescriptions, and your budget. A few practical steps:

1. List your doctors and hospitals. If you want to stay with them, check each plan's network before enrolling. 2. List your prescriptions, with doses. Drug coverage varies plan to plan. The same medication can be covered differently or require prior approval on one plan versus another. 3. Think about how you like to get care. Do you travel often? Prefer a referral-based system or the freedom to see any specialist? That shapes whether Original Medicare with a supplement or a Medicare Advantage plan makes more sense. 4. Look at the total picture, not just the premium. Deductibles, copays, and out-of-pocket maximums all add up differently depending on how much care you use.
