Difference Between QMB and SLMB — Minnesota Medicare Savings Program Tiers Compared
What Each Tier Actually Covers
The Medicare Savings Programs in Minnesota split into tiers based on income, and the coverage difference between them is substantial — not just a matter of degree.
QMB is the most comprehensive. It pays the Part B premium ($202.90/month in 2026), the Part A premium if you don't have premium-free Part A, plus all Medicare deductibles, coinsurance, and copays. Providers are legally prohibited from balance billing you for any Medicare cost-sharing. If your parent has QMB and a doctor sends a bill for the Part B deductible, that bill is illegal under federal law (42 U.S.C. § 1396a(n)(3)(B)).
SLMB pays only the Part B premium. No deductibles, no coinsurance, no copay coverage. The practical impact is still significant — $202.90 stays in the Social Security check each month instead of being withheld, which adds $2,434.80 per year to spendable income.
QI covers the same thing as SLMB — just the Part B premium — but at a higher income threshold. The catch: QI runs on a capped federal block grant, renewed annually. Enrollment is first-come, first-served, with priority given to people enrolled the previous year. Running out of funding mid-year is theoretically possible, though Minnesota has not turned away QI applicants in recent years.
The Income Cutoffs
All three tiers use the same asset limit in Minnesota: $10,000 for an individual, $18,000 for a couple. The difference is the income threshold, expressed as a percentage of the Federal Poverty Guidelines and adjusted by Minnesota's $20 standard unearned income disregard:
| Tier | FPG Percentage | Individual Monthly Income | Couple Monthly Income |
|---|---|---|---|
| QMB | 100% FPG | Up to $1,330 | Up to $1,803 |
| SLMB | 120% FPG | $1,331 – $1,596 | $1,804 – $2,164 |
| QI | 135% FPG | $1,597 – $1,795 | $2,165 – $2,434 |
These are countable income figures after the $20 disregard. Minnesota uses gross Social Security — the amount before Part B is deducted — as the starting number.
Why the Tier Matters Beyond Premiums
All three tiers trigger automatic full Extra Help (Part D Low-Income Subsidy). Regardless of whether your parent qualifies for QMB, SLMB, or QI, CMS receives an electronic file from Minnesota DHS and enrolls them in full Extra Help: a $0 premium in a benchmark Part D plan, a $0 deductible, and maximum copays of $5.10 for generic or preferred multi-source drugs and $12.65 for other covered drugs in 2026. Some Extra Help recipients pay less, depending on their eligibility category. The $2,100 annual out-of-pocket drug cap applies after that.
The tier also affects dual-eligible plan options. QMB enrollees can access Dual-Eligible Special Needs Plans (D-SNPs), which combine Medicare Advantage with Medicaid-like supplemental benefits — dental, vision, transportation, and care coordination. SLMB and QI enrollees may qualify for some D-SNP options depending on the plan's specific enrollment criteria.

Choosing the Right Application Strategy
You don't choose your tier — the county determines it based on your income and assets. But knowing the boundaries helps you screen before applying. If your parent's countable income is $1,500/month, they fall into the SLMB range. If it's $1,700, they're in QI territory. Either way, the application form is the same DHS-3876, submitted to the county human services office.
