Missouri QMB vs SLMB: Which Medicare Savings Program Do You Qualify For?

The Short Answer

QMB covers almost everything. SLMB covers one thing.

Both are Medicare Savings Programs administered by Missouri's Family Support Division (FSD). Both use the same application form (IM-1MSP) and the same resource limit ($9,660 individual, $14,470 couple). The difference comes down to income and what gets paid.

QMB — Qualified Medicare Beneficiary — pays your Part A premiums, Part B premiums ($202.90/month in 2026), hospital deductibles ($1,676 per benefit period), the Part B annual deductible, and all coinsurance and copayments on Medicare-covered services. It also triggers federal billing protections under 42 CFR 447.15, meaning providers cannot legally send you a bill for any of those costs.

SLMB — Specified Low-Income Medicare Beneficiary — pays your Part B monthly premium as an MSP benefit. On its own, SLMB doesn't include QMB's protection against Medicare cost-sharing bills.

Income Limits Side by Side

The dividing line is the Federal Poverty Level. After FSD applies the standard $20 monthly unearned income disregard, countable income determines which tier you land in:

If your countable income is $1,240/month, you qualify for QMB. At $1,400/month, you're above QMB's ceiling but inside SLMB's range. At $1,600/month, you'd be in QI-1 territory.

FSD uses gross Social Security — the full benefit amount before Part B premium deductions, tax withholdings, or garnishments are subtracted. The number on your bank deposit is lower than what FSD counts.

What About Full Medicaid?

MSP and full MO HealthNet (Medicaid) are separate programs, though they can overlap.

QMB can run alongside full Medicaid — that combination is called QMB+. You get QMB's Medicare cost-sharing coverage on top of Medicaid's broader medical benefits. SLMB has a similar overlap: SLMB Group 2 (sometimes written SLMB+) is SLMB plus full MO HealthNet.

QI-1 is the exception. Federal rules prohibit holding QI-1 and full MO HealthNet at the same time. If you qualify for full Medicaid, you lose QI-1 eligibility — but full Medicaid typically covers more anyway.

The practical difference: MSP eligibility uses higher resource limits ($9,660/$14,470) than the full MO HealthNet Aged, Blind, and Disabled program ($5,000/$10,000). Someone whose savings disqualify them from full Medicaid might still qualify for QMB or SLMB.

Extra Help and MoRx: Both Tiers Unlock Them

Approval for any MSP tier — QMB, SLMB, or QI-1 — automatically qualifies you for Full Extra Help (Part D Low-Income Subsidy). That eliminates the Part D prescription deductible, caps drug copays at a few dollars per fill, and provides $0 premiums on benchmark Part D plans.

All MSP tiers also qualify for automatic MoRx enrollment if you're enrolled in a Medicare Part D plan. Missouri's Rx Plan pays 50% of remaining out-of-pocket prescription costs after Part D pays its share. No separate MoRx application is needed if you're enrolled in Part D.

So while SLMB covers less on the medical side, it still unlocks the same prescription drug savings as QMB.

How to Figure Out Which One You Qualify For

Start with gross Social Security. Find your parent's full monthly benefit amount on their SSA-1099 or Social Security award letter — not the bank deposit. Subtract $20 (the standard unearned income disregard). Compare the result to the table above.

If the number lands below $1,255 (individual), apply for QMB. If it falls between $1,255 and $1,506, apply for SLMB. FSD determines the tier based on the income you report — you don't need to pick one yourself. Submit Form IM-1MSP and FSD places you in the highest tier you qualify for.

One timing detail: QMB coverage starts the first day of the month after FSD approves the application. SLMB and QI-1 allow up to three months of retroactive coverage if you met the income and resource criteria during those months. That retroactive window can recover Part B premiums that were already deducted.
