Medicare 101
Medicare vs Medicaid
Medicare and Medicaid sound alike but are two different programs. Medicare is federal health insurance mainly for people 65 and older (and some younger people with disabilities), and you qualify regardless of your income. Medicaid is a joint federal-and-state program for people with limited income and resources. If you qualify for both at the same time, you're called "dual-eligible" and may receive extra help with your costs — often through a Dual Special Needs Plan (D-SNP), and there are strong D-SNP options across our service area.
Medicare in one paragraph
Medicare is run by the federal government and is tied mainly to age and work history, not income. Most people qualify at 65; some qualify earlier through disability, ALS, or End-Stage Renal Disease. It's built from Part A (hospital), Part B (medical), Part C (Medicare Advantage private plans), and Part D (drugs). You generally earn premium-free Part A by paying Medicare taxes for about 10 years. Because it's federal, the core rules are the same in South Dakota as anywhere else in the country.
Medicaid in one paragraph
Medicaid is run jointly by the federal government and each state, so the income limits and covered benefits vary by where you live — South Dakota's rules differ from Iowa's or Minnesota's. Eligibility is based on income and, in many cases, assets and household size. Medicaid often covers services Medicare doesn't, most notably long-term custodial care in a nursing home or at home. For people with limited resources, it can dramatically lower what they pay out of pocket for care.
When you have both: dual eligibility
Some people qualify for Medicare and Medicaid at the same time — typically older adults with limited income. When that happens, Medicare pays first and Medicaid helps cover much of what's left, including premiums, deductibles, and copays in many situations. Dual-eligible individuals often qualify for a Dual Special Needs Plan (D-SNP), a type of Medicare Advantage plan built for this group that can carry a $0 plan premium and very low costs. We can verify your status and, if you're eligible, enroll you in a plan we offer.
D-SNP options across the Big Sioux region
Dual-eligible residents in our area have real choice. On the Iowa side, Sioux County alone has 8 or more dual-eligible (D-SNP) plans from carriers like Humana, Molina, Wellcare, Wellpoint, and UnitedHealthcare (CMS PY2026; verify current plans on Medicare.gov), and the Sioux Falls side offers D-SNP plans from carriers including Aetna and UnitedHealthcare. These plans coordinate your Medicare and Medicaid and often add allowances for groceries, over-the-counter items, and transportation. Because the lineup differs by county, we compare the dual plans we offer where you actually live.
Extra Help and the Medicare Savings Programs
Even if you don't qualify for full Medicaid, you may qualify for related assistance. "Extra Help" (the Low-Income Subsidy) lowers Part D prescription drug costs for people with modest income and resources. The Medicare Savings Programs can pay your Part B premium and other costs. These programs sit between full Medicaid and paying everything yourself, and many people who'd qualify never apply simply because they don't know the programs exist. We can point you to how to check your eligibility.
Sioux Falls area: which door to knock on
Because Medicaid is state-administered, the right contact depends on where you live across our service area — South Dakota, northwest Iowa, or southwest Minnesota each run their own Medicaid offices and income limits. Medicare questions, by contrast, go to the federal government or to a local agent like us. If you think you might qualify for both, start with us: we can help you understand the Medicare side, flag whether a dual plan we offer fits, and direct you to the right state resource for the Medicaid determination.
Questions, answered
Can I have Medicare and Medicaid at the same time?
Yes. Qualifying for both is called being "dual-eligible," and it's common among older adults with limited income. When you have both, Medicare pays first and Medicaid helps with much of what's left — often premiums, deductibles, and copays. Many dual-eligible people also qualify for a Dual Special Needs Plan (D-SNP) that can have a $0 plan premium and added benefits. We can verify your status and check whether a dual plan we offer is a fit.
What's the main difference between Medicare and Medicaid?
Medicare is federal and based mainly on age — most people qualify at 65 no matter their income. Medicaid is a joint federal-state program based on limited income and resources, with rules that vary by state. Medicare focuses on hospital, medical, and drug coverage; Medicaid often adds long-term custodial care that Medicare won't pay for. In short: Medicare is the age-based program, Medicaid is the income-based one, and some people qualify for both.
Does Medicaid pay for things Medicare doesn't?
Often, yes. The biggest example is long-term custodial care — extended help with daily activities in a nursing home or at home — which Original Medicare and Medicare Advantage generally don't cover but Medicaid frequently does for those who qualify. Medicaid may also help with premiums, copays, and deductibles for dual-eligible members. Because Medicaid is state-run, the exact benefits differ across South Dakota, Iowa, and Minnesota, so it's worth confirming your local rules.
Is Medicare based on income like Medicaid?
Mostly no. You qualify for Medicare on age and work history, not income, so a high earner and a low earner both qualify at 65. Income only affects how much you pay — higher earners pay an IRMAA surcharge on Parts B and D. Medicaid is the income-based program, with limits on income and often assets. So income changes your Medicare costs but is the gatekeeper for Medicaid eligibility itself.
What is Extra Help and how is it different from Medicaid?
Extra Help, also called the Low-Income Subsidy, is a federal program that lowers Part D prescription drug costs — premiums, deductibles, and copays — for people with limited income and resources. It's narrower than full Medicaid, which covers a broad range of medical and long-term care services. You can qualify for Extra Help without qualifying for full Medicaid. Many people who'd be eligible never apply, so it's worth checking. We can point you to how.
What is a D-SNP, and could I qualify for one?
A Dual Special Needs Plan (D-SNP) is a type of Medicare Advantage plan built for people who have both Medicare and Medicaid. It coordinates the two programs and often adds benefits like grocery and over-the-counter allowances, transportation, and care coordination, frequently at a $0 plan premium. You generally qualify if you have Medicaid or get help through a Medicare Savings Program. We verify your status and, if you're eligible, compare the D-SNP plans we offer in your county.
How many dual-eligible plans are available in this area?
It depends on your county. On the Iowa side, Sioux County has 8 or more D-SNP plans from carriers like Humana, Molina, Wellcare, Wellpoint, and UnitedHealthcare, while the Sioux Falls side offers dual plans from carriers including Aetna and UnitedHealthcare (CMS PY2026; verify current plans on Medicare.gov). Because the lineup and extra benefits vary from one county to the next, we compare the dual plans we offer where you live so you see the choices that actually apply to you.
Does a D-SNP cost anything if I'm dual-eligible?
Often very little. Many D-SNPs carry a $0 plan premium and low or no copays, because Medicaid coordinates with the plan to cover much of your cost-sharing. You still keep paying your Part B premium unless a Medicare Savings Program covers it for you. Exact costs and extra benefits vary by plan and can change yearly, so we compare the dual plans we offer in your county to find the package that fits your doctors and prescriptions.
What happens to my dual plan if I lose Medicaid?
D-SNP eligibility depends on keeping both Medicare and Medicaid (or a qualifying Savings Program), so losing Medicaid can affect your plan, sometimes after a grace period. It's important to report changes promptly and understand your options before coverage shifts. We help you track your status, explain any grace period, and find suitable coverage among the plans we offer if your eligibility changes, so you're never left without a plan that fits.
Where do I apply for Medicaid in South Dakota?
Because Medicaid is state-run, you apply through your state's Medicaid agency — South Dakota, Iowa, and Minnesota each run their own offices and income limits. We don't make the Medicaid determination, but we can help you understand the Medicare side, flag whether you might qualify for a dual plan we offer, and point you to the right state resource to apply. Starting with us means you tackle both programs in one conversation rather than guessing.
