South Dakota Medicare Savings Programs pay Medicare premiums and cost-sharing for income-eligible seniors and people with disabilities. The top tier, QMB, eliminates the Part B premium and all Medicare cost-sharing in a single program.
What Are Medicare Savings Programs?
Medicare Savings Programs are Medicaid-administered benefits that pay some or all of a low-income Medicare beneficiary's Medicare premiums and cost-sharing. QMB, SLMB, and QI are mandatory eligibility groups under Title XIX of the Social Security Act, so every state plan must cover them.
South Dakota Department of Social Services (DSS) administers all three programs through its Economic Assistance division. Eligibility for MSPs uses the SSI-related income methodology, which includes two income disregards: a $20/month general income disregard applied to unearned income, and a $65 plus half of remaining earned income disregard for working applicants. The income bands below already reflect the $20 disregard.
QMB: Qualified Medicare Beneficiary
QMB is the broadest of the three programs. It covers:
- The Medicare Part A premium (most beneficiaries have premium-free Part A after 40 work quarters)
- The Medicare Part B premium ($185.00/month standard rate in 2026 per CMS)
- The Part A inpatient hospital deductible ($1,736 in 2026)
- The Part B annual deductible ($257 in 2026)
- All Medicare coinsurance and copays on every Medicare-covered service
2026 South Dakota QMB income limits: at or below $1,350/month for a single person, or at or below $1,823/month for a couple. These figures reflect 100% of the Federal Poverty Level with the $20 disregard applied.
Resource limit: $9,950 for one person, $14,910 for a couple. The primary residence and one vehicle are excluded entirely from the resource count.
For a single South Dakota senior on Social Security, QMB can be worth more than $3,000 a year in saved premiums, deductibles, and copays. Every QMB enrollee is automatically deemed eligible for full Part D Extra Help.
SLMB: Specified Low-Income Medicare Beneficiary
SLMB covers one benefit: the Medicare Part B premium. At the 2026 standard rate, that is $2,220.00 per year.
2026 South Dakota SLMB income limits: $1,351 to $1,616/month for a single person, $1,824 to $2,186/month for a couple.
Resource limit: same as QMB: $9,950 single, $14,910 couple.
SLMB does not pay deductibles or copays. For a beneficiary with relatively few Medicare claims, the Part B premium is the dominant annual cost, and SLMB addresses it directly.
SLMB also confers automatic Part D Extra Help, which can cut drug costs to $5.10/generic and $12.65/brand-name copays with a $0 deductible and $0 premium on a benchmark Part D plan.
QI: Qualifying Individual
QI covers the Part B premium only, at a higher income band: $1,617 to $1,816/month for a single person, $2,187 to $2,457/month for a couple (2026 South Dakota figures).
Two structural differences from QMB and SLMB:
- First-come, first-served. QI is funded through a capped federal allotment. DSS allocates enrollment first-come, first-served, with preference for prior-year QI enrollees. QI is not an entitlement, unlike QMB and SLMB.
- Mutually exclusive with full Medicaid. If you qualify for any full-benefit Medicaid category, you cannot be on QI. You would instead qualify for QMB-Plus or SLMB-Plus, which combine MSP cost-sharing protection with full Medicaid.
Like SLMB, QI enrollment triggers automatic Part D Extra Help.
The QMB Billing Prohibition
Federal law, specifically 42 USC § 1396a(n)(3)(B), prohibits any Medicare provider from billing a QMB enrollee for Medicare cost-sharing. This covers Original Medicare and Medicare Advantage providers alike, whether or not they participate with South Dakota Medicaid.
In plain terms: if you are a QMB enrollee and receive a bill for a deductible, coinsurance, or copay on a Medicare-covered service. Do not pay it. The provider is legally prohibited from collecting it.
If you receive such a bill:
- Tell the provider you are a QMB enrollee and cite federal law.
- Show your DSS eligibility notice or Medicare card with the QMB indicator.
- Call 1-800-MEDICARE (1-800-633-4227) to file a complaint.
- Contact the South Dakota State Health Insurance Assistance Program (SHIAP) for free help.
A provider who has billed a QMB must recall the bill from any collections process and refund payments already collected.
Part D Extra Help / Low-Income Subsidy
Every QMB, SLMB, and QI enrollee in South Dakota is automatically deemed eligible for full Part D Extra Help (also called the Low-Income Subsidy, or LIS). No separate application is required.
Under the 2026 Part D benefit structure:
- $0 Part D premium on a benchmark plan
- $0 annual deductible
- $5.10 per generic prescription
- $12.65 per brand-name or preferred multi-source drug
- $0 in copays after the annual out-of-pocket cap
For a senior filling six prescriptions per month, Part D Extra Help can represent $1,500 to $2,500 in annual drug-cost savings on top of the Part B premium benefit from SLMB or QI.
The deeming flows automatically from DSS to CMS each month. If you are not already in a Part D plan, CMS will auto-assign you to a zero-premium benchmark plan.
South Dakota Medicare Savings Programs: 2026 Income Limits at a Glance
| Program | Single monthly income limit | Couple monthly income limit | What it pays |
|---|---|---|---|
| QMB | $1,350 | $1,823 | Part A + Part B premiums + all cost-sharing |
| SLMB | $1,351-$1,616 | $1,824-$2,186 | Part B premium only |
| QI | $1,617-$1,816 | $2,187-$2,457 | Part B premium only (capped allotment) |
Income limits reflect 100% FPL (QMB), 100-120% FPL (SLMB), and 120-135% FPL (QI) with the $20 general income disregard applied. Resource limit for all three: $9,950 single / $14,910 couple.
What Counts as a Resource, and What Doesn't
The $9,950/$14,910 resource test excludes several major asset categories:
Excluded (don't count):
- Primary residence, regardless of value or equity
- One vehicle, regardless of make, model, or value
- Household goods and personal effects
- Prepaid burial arrangements and a burial fund up to $1,500 per person
Counted:
- Checking and savings account balances
- Stocks, bonds, certificates of deposit, mutual funds
- A second vehicle or second home
- Non-exempt cash-value life insurance above the face-value threshold
A QMB applicant in a paid-off house can still qualify provided bank balances and other financial assets stay within $9,950. The home is not counted.
How to Apply for South Dakota Medicare Savings Programs
South Dakota offers three application pathways:
1. Online via the DSS Economic Assistance portal Apply at eaportal.sd.gov. This is the DSS portal for Medicaid and related benefit programs. Complete the application and upload supporting documents online.
2. In person at a local DSS county office Bring your Medicare card, Social Security award letter, recent bank statements, and proof of South Dakota residency. DSS staff will assist with the paper application.
3. By phone Call DSS at 1-605-773-3165. Staff can take applications by phone for applicants who cannot use the online portal or visit a county office.
Through SSA. Applying for Part D Extra Help at your Social Security office using Form SSA-1020 generates an automatic referral to South Dakota Medicaid under federal law (42 USC § 1320b-14). Your SSA application date serves as the protected filing date.
Documents to Gather Before You Apply
- Medicare card (showing your Medicare Beneficiary Identifier / MBI)
- Social Security card or proof of Social Security number
- Most recent SSA benefit award or COLA letter
- Recent bank and investment account statements
- Pension or annuity statements, if applicable
- Proof of South Dakota residency (utility bill, lease, or mortgage statement)
Effective Dates and Retroactive Coverage
- QMB: coverage begins the first day of the month after DSS approves your application. Federal law (42 USC § 1396a(e)(8)) prohibits retroactive QMB coverage. Apply early.
- SLMB and QI: up to three months of retroactive coverage is available under 42 CFR § 435.915 if you were eligible during that window. File early even if you cannot gather every document on day one.
After approval, DSS sends a written eligibility notice. For QMB, a state buy-in notice goes to CMS, which stops withholding the Part B premium from your Social Security check the following month.
