Yes. Losing Medicaid raises Medicare cost sharing for most dementia patients who have both programs.
These patients, called dual-eligible beneficiaries, keep Medicare but lose Medicaid help with premiums, deductibles, and copayments. That shift matters because dementia care uses many doctor visits, tests, and hospital services. Without Medicaid, the family pays Medicare bills that Medicaid once covered.

What Medicaid was paying for
Medicaid help often comes through state Medicare Savings Programs. According to KFF, people who lose Medicaid generally keep Medicare as primary coverage but lose Medicaid payment of Medicare premiums and, in most cases, deductibles, coinsurance, and copayments KFF analysis of reconciliation-bill cost effects.
The strongest protection is the Qualified Medicare Beneficiary program, called QMB. According to Medicare, the QMB program pays Part A premiums if owed plus Part B premiums, deductibles, coinsurance, and copayments, and federal law bars Medicare providers from billing QMB patients for covered cost sharing Medicare's guide to Medicare Savings Programs.
How much could you owe without it
The amounts are large in 2026. According to the Centers for Medicare and Medicaid Services, the 2026 amount is a $202.90 monthly Part B premium plus a $283 annual deductible and usually 20% coinsurance with no annual cap the 2026 Medicare premiums announcement.
A family would therefore pay the monthly premium plus the deductible. Then each covered visit or procedure can add 20% coinsurance. Repeat neurology visits, imaging, lab work, and hospital care can make that share grow fast.
Why dementia increases the risk
Dementia patients use more medical care than many other older adults. According to USC Schaeffer Center research, dual-eligible beneficiaries with dementia had about $54,500 in per-person medical spending in 2023 versus $40,900 for Medicare-only beneficiaries with dementia USC Schaeffer Center dementia cost research.
Medicaid also pays for long-term supports that add to the loss. The Alzheimer's Association reports average annual Medicaid payments of about $7,158 for Medicare beneficiaries age 65 and older with Alzheimer's or other dementias versus $322 without dementia, about 22 times higher. That gap reflects years of custodial care Medicare generally does not cover.
Which protections do not cover everything
A partial Savings Program leaves major bills in place. Medicare reports that Specified Low-Income Beneficiary and Qualifying Individual programs pay only the Part B premium, so beneficiaries remain liable for deductibles and 20% coinsurance.
Provider payment also has a limit. An NIH/PMC modeling study notes state "lesser-of" policy: although Medicaid pays the 20% Part B copayment for duals, states may reimburse only up to the lower Medicaid rate rather than full Medicare cost sharing. That rule can reduce payment to doctors and clinics, which may affect access to dementia evaluation.
What should families check now
Confirm whether coverage was full Medicaid, QMB, or a premium-only Savings Program. Full loss and QMB loss create the largest new liability. Premium-only status still leaves deductibles and coinsurance with the family.
- Ask the state Medicaid office whether QMB, SLMB, or other Savings Program enrollment remains active.
- Ask each Medicare provider not to bill for covered cost sharing while QMB is active.
- Review drug costs, because QMB enrollment brings automatic Extra Help limiting 2026 prescription copays to no more than $12.65 per covered drug.
- Track deductibles, 20% bills, and premium notices separately after Medicaid ends.
