Ohio Dual Eligible: Medicare and Medicaid Together

What Dual Eligible Means in Ohio

A dual-eligible beneficiary has both Medicare and Medicaid coverage simultaneously. In Ohio, roughly 500,000 people fall into this category, and the specific combination of programs they carry determines what's covered and what they owe.

The distinction that matters most is between full duals and partial duals:

Full duals have full-benefit Ohio Medicaid plus Medicare. They receive comprehensive coverage — Medicare handles hospital and doctor services, Medicaid fills the gaps with dental, vision, hearing, transportation, and long-term care services. Most full duals also carry QMB or SLMB status, which means Medicaid pays their Medicare premiums and (for QMB) all Medicare cost-sharing.

Partial duals have a Medicare Savings Program (QMB, SLMB, or QI) but not full Medicaid. The MSP pays their Part B premium and, for QMB, Medicare deductibles and coinsurance. But they don't receive full Medicaid benefits like dental, transportation, or long-term care.

QMB-Plus and SLMB-Plus

When someone qualifies for both full Medicaid and a Medicare Savings Program, Ohio designates them with a combined status:

QMB-Plus means full Medicaid plus QMB. The beneficiary gets full Medicaid services and QMB's complete Medicare cost-sharing protection — no Medicare deductibles, copays, or coinsurance. Providers cannot bill them for any Medicare Part A or Part B cost-sharing under any circumstances.

SLMB-Plus means full Medicaid plus SLMB. Medicaid pays the Part B premium and provides full Medicaid benefits. SLMB-Plus doesn't include the cost-sharing protection that QMB provides, but full Medicaid itself typically covers what Medicare's cost-sharing would have been, through Medicaid's own fee schedule.

The practical difference: QMB-Plus carries explicit billing protection under 42 CFR 447.15 — providers are categorically prohibited from billing the patient. SLMB-Plus coverage achieves a similar result through Medicaid's coverage of cost-sharing, but the legal mechanism is different.

QI Cannot Overlap With Full Medicaid

One important rule: QI (Qualifying Individual) eligibility is mutually exclusive with full-benefit Medicaid. You cannot be enrolled in both. If someone receiving QI later qualifies for full Medicaid, they'd transition to QMB-Plus or SLMB-Plus status depending on their income level, and QI coverage would end.

This matters when helping a parent explore both programs. If they're already on full Medicaid and Medicare, asking about QI is unnecessary — they're already covered by the stronger combination.

Extra Help for All Duals

Every dual-eligible beneficiary — whether full dual or partial dual through QMB, SLMB, or QI — automatically receives full Extra Help for Medicare Part D prescription drugs. In 2026, that means $0 premiums on benchmark plans, $0 deductibles, and copays of up to $5.10 for generics and $12.65 for brand-name drugs.

Full duals also get Special Enrollment Period rights, allowing them to switch Part D plans once per quarter during the first nine months of the year (January through September).

The Estate Recovery Distinction

The combination matters for estate recovery. Ohio can pursue estate recovery for full Medicaid benefits — particularly nursing home care and home-and-community-based waiver services. But MPAP benefits (the Part B premium, QMB cost-sharing) are exempt from estate recovery under federal law, even when they're part of a QMB-Plus or SLMB-Plus package.

If a parent is on full Medicaid for long-term care and also has QMB status, estate recovery applies to the Medicaid long-term care portion — not to the QMB premium and cost-sharing assistance.
