Medicare Advantage in Irmo: 2027 Plan Tally

Medicare Advantage availability in Irmo, South Carolina for 2027 — plain-language plan counts and key dates.

IRMO, S.C. — If you live in Irmo and you're sizing up Medicare coverage for 2027, it helps to know that plan choices are set county by county — not city by city. That means the menu you see depends on which side of a county line your home sits on, and neighbors just a few miles away may be shopping from a different list.

Irmo straddles parts of the Midlands, and Richland County is one of the main counties serving the area. Looking at nearby counties side by side is one of the clearest ways to understand what "available in your area" really means.

Why availability is a county-level story

Medicare Advantage and Part D plans are approved to serve specific service areas, and those service areas are drawn using counties. So when you use Medicare.gov's Plan Finder, it asks for your ZIP code and then looks up the county behind it.

For Irmo residents, that usually means Richland County, though the town's footprint touches other counties too. If you move — even across town — your plan list can change. It's worth checking your ZIP directly rather than assuming a friend's options match yours.

What the numbers look like around Irmo

According to CMS Medicare Advantage and Part D Landscape data for 2026, Richland County had 58 Medicare Advantage plans available, offered by 9 carriers with prescription drug coverage built in. The county is home to about 59,468 people age 65 and older, so there's a large pool of neighbors sorting through the same choices you are. The 2027 lineup is detailed in each plan's Annual Notice of Change and on Medicare.gov's Plan Finder.

A couple of notes on the local picture:

• Stand-alone Part D plans are counted separately from Medicare Advantage. If you're staying with Original Medicare and want drug coverage, you'll want to check current Part D options directly on Medicare.gov.
• Star Ratings are a quality measure CMS publishes each year. They're a helpful data point when comparing plans, but they aren't the whole story — cost, drug coverage, and doctor networks matter too.

How to decide when the list feels long

Fifty-plus plans is a lot to read through. A few filters can shrink the list quickly:

1. Start with your doctors and hospitals. If you have providers you want to keep, check each plan's network first. That alone often narrows things down a lot. 2. Add your prescriptions. Plan Finder lets you enter your medications and see how each plan covers them. Two plans that look similar on paper can treat the same drug very differently. 3. Think about how you like to get care. Some plans use HMOs with referrals; others are PPOs with more flexibility. Neither is "better" — it depends on how you use care. 4. Consider the whole year, not just January. Look at deductibles, coinsurance, and out-of-pocket maximums, not only monthly premiums.

2027 rules that apply no matter where you live

Some things don't change from county to county. For 2027:

• Part D has a $2,400 annual out-of-pocket cap on covered drugs in 2027 (it is $2,100 in 2026). Once you hit it, you pay nothing for covered prescriptions the rest of the year.
• The maximum Part D deductible is $700 in 2027 ($615 in 2026), though many plans set theirs lower.
• The old coverage gap (donut hole) is gone as of 2025. Part D now has three phases: deductible, initial coverage, and catastrophic.
• The Medicare Prescription Payment Plan lets you spread your drug costs across the year in monthly payments, if that helps with budgeting.
• IRMAA surcharges for higher-income beneficiaries begin above $109,000 in income for a single filer in 2026.

Key dates to circle

• Oct. 15 – Dec. 7: Annual Enrollment Period. You can join, switch, or drop a Medicare Advantage or Part D plan. Changes take effect Jan. 1.
• Jan. 1 – March 31: Medicare Advantage Open Enrollment Period. If you're already in an MA plan, you get one chance to switch to another MA plan or return to Original Medicare (and add a Part D plan).
