What Does QMB Cover in Illinois?

The Full Scope of QMB Benefits

QMB is the most comprehensive of Illinois's three Medicare Savings Programs. While SLMB and QI-1 pay only the Part B premium, QMB pays Part A and Part B premiums and protects beneficiaries from Medicare deductibles, coinsurance, and copayments. Illinois Medicaid may pay less than the full cost-sharing amount under its "lesser-of" method; providers must write off the rest rather than bill the QMB beneficiary.

Here's what that means in 2026 dollars.

Premiums QMB Pays

Part B premium: $202.90 per month, paid by the state through the buy-in system. After approval, SSA stops deducting this from the Social Security check (though the handoff takes two to four months, and overpaid months are refunded).

Part A premium (when applicable): Most people get Part A free based on 40 quarters of work history. But for those who don't — people who worked fewer than 30 quarters pay $565 per month, those with 30–39 quarters pay $311 per month. QMB pays this through Illinois's group-payer agreement with SSA. For someone without premium-free Part A, this is the single largest benefit: $6,780 per year at the higher rate.

Deductibles and Coinsurance QMB Covers

Part A hospital deductible: $1,736 per benefit period in 2026. QMB protects the beneficiary from being billed for this deductible on a Medicare-covered inpatient stay; Illinois Medicaid may pay less than the full amount, with the provider writing off the remainder.

Part A hospital coinsurance: $434 per day for days 61–90 of a hospital stay, $868 per day for lifetime reserve days beyond day 90. QMB protects the beneficiary from being billed for these Medicare cost-sharing amounts.

Skilled nursing facility coinsurance: $217 per day for days 21–100. Without QMB, a 100-day SNF stay would cost the patient $17,360 in coinsurance alone.

Part B annual deductible: $283 per year. QMB protects the beneficiary from being billed for this deductible.

Part B coinsurance and copayments: Medicare typically pays 80% of approved amounts for doctor visits, outpatient procedures, lab work, and durable medical equipment. QMB beneficiaries cannot be billed for the remaining Medicare cost-sharing. Illinois Medicaid may pay part or none of the balance under the "lesser-of" method, and the provider must write off any unpaid amount. For someone with frequent medical appointments or ongoing treatment, this protection can be worth hundreds or thousands of dollars per year.

What QMB Does Not Cover

QMB pays Medicare's cost-sharing — it doesn't expand what Medicare covers. Services that Medicare itself doesn't cover remain uncovered by QMB alone:

• Routine dental care, dentures, and most dental procedures
• Routine vision exams and eyeglasses (beyond a one-time pair after cataract surgery)
• Hearing aids (though Medicare began covering some hearing services)
• Long-term custodial care in a nursing home
• Most care received outside the United States

If the beneficiary also qualifies for full-scope Medicaid (AABD Medical), those additional services may be covered under the Medicaid benefit package. Many QMB recipients in Illinois are dual eligible — enrolled in both Medicare and Medicaid.

Federal Balance Billing Protections

By law, Medicare providers cannot bill QMB patients for deductibles, coinsurance, or copayments — even if the provider hasn't received payment from Medicaid yet. This protection is codified at 42 U.S.C. § 1396a(n)(3)(B) and applies whether the provider accepts Medicaid or not.

In practice, providers still send bills. Some don't check QMB status, others don't understand the prohibition, and a few send balances to collections despite it being illegal. If this happens, the patient or family member can contact the provider's billing department, cite the federal balance billing prohibition, and request the bill be withdrawn. The Illinois Medicare Savings Programs & Extra Help Guide includes a dispute letter template that references the specific statute.

Extra Help Comes Automatically

Every QMB recipient is automatically deemed eligible for Extra Help (the Part D Low-Income Subsidy), which reduces prescription drug copays, eliminates the Part D deductible, and provides premium assistance for Part D plans. No separate application to SSA is needed — QMB approval triggers it through the CMS data exchange.
