Medicare Savings Programs and Extra Help in SD

Three programs, three different jobs

It helps to separate the programs, because they come from different places and you apply in different places.

• Medicare Savings Programs (MSPs) are state programs, funded with federal help, that pay Medicare premiums and sometimes other Medicare costs. In South Dakota they are administered by the Department of Social Services (DSS).
• Extra Help, also called the Low-Income Subsidy, is a federal Medicare program that helps pay Part D drug coverage costs. You apply through Social Security, according to Medicare.gov.
• Medicaid is a joint federal and state program. South Dakota DSS describes it as health coverage for people who meet certain eligibility standards, paying for hospital stays, doctor visits, prescriptions and other care. People with both Medicare and Medicaid are often called dual eligible.

For the broader difference between the two big programs, see our existing guide to Medicare vs Medicaid.

Medicare Savings Programs in South Dakota

South Dakota DSS lists three Medicare Savings Program groups on its medical programs page:

Source: South Dakota DSS, Medical Programs (fetched October 19, 2026); Medicare.gov, Medicare Savings Programs (2026 federal limits).

DSS says the income limit is based on family size and the adjusted income of the adults in the household, and that the resource limit is $9,950 for an individual and $14,910 for a couple. Resources include checking and savings accounts and certificates of deposit. Medicare.gov adds that up to $1,500 set aside for burial expenses is not counted, and that states may qualify people even above the federal limits, so the federal figures in the table are a guide rather than the last word. Apply even if you think you are close.

What it is worth: DSS says the program can save people up to $2,434.80 a year. That matches twelve months of the 2026 standard Part B premium of $202.90, from the CMS 2026 fact sheet.

Two details people miss

• If you qualify for QMB, Medicare.gov says Medicare providers are not allowed to bill you for Medicare-covered services, including deductibles, coinsurance and copayments. Show both your Medicare card and your Medicaid or QMB card every time you get care.
• For QI, Medicare.gov says you must apply every year, and states approve applications first come, first served.
• Enrolling in a Medicare Savings Program also avoids the Part B late enrollment penalty, according to Medicare.gov.

Extra Help with drug costs

Medicare.gov lists the 2026 limits for Extra Help as income under $23,940 and resources under $18,090 for an individual, or income under $32,460 and resources under $36,100 for a married couple. The limits may go up each year.

You get Extra Help automatically if you have full Medicaid, are in a Medicare Savings Program, or get Supplemental Security Income (SSI). Everyone else applies through Social Security. Medicare.gov notes that when you apply for Extra Help, Social Security sends your information to the state to start a Medicare Savings Program application unless you say not to. While you get Extra Help, you also do not pay a Part D late enrollment penalty, and the CMS Medicare & You 2027 handbook says you can change drug coverage once a month.

Medicaid for people on Medicare

Full Medicaid has its own rules in South Dakota, and the ones that matter most to people on Medicare are often about long-term care. DSS lists, for people in nursing facilities or using its HOPE home and community-based waiver, that a person must be 65 or older (or blind or disabled), need a nursing-home level of care, have monthly income no more than 300% of the SSI standard benefit, which it gives as $2,982 in 2026, and resources no more than $2,000.

People with both Medicare and full Medicaid can often join a Dual Eligible Special Needs Plan (D-SNP), a Medicare Advantage plan built around both programs. Our existing page on special needs plans explains them, and our newsroom covers the D-SNP changes around Sioux Falls.

How to apply in South Dakota

DSS's medical eligibility page gives three ways to apply for Medicare Savings Programs and Medicaid:

1. Online, through the South Dakota Economic Assistance portal.
2. On paper, using the Medicare Savings Program application (a PDF from DSS) or the general application.
3. With help from DSS staff; the page lists this as its third option.

DSS says that when you apply for the Medicare Savings Program you must send proof of Medicare enrollment, so have your Medicare card ready. For Extra Help, apply through Social Security. If you live near the Iowa or Minnesota border, remember that these are state programs: you apply in the state where you live. Medicaid.gov lists each state's agency.
