Dual eligible
When both programmes cover you
Around one in five people with Medicare also qualify for help from Medicaid — and a good number of them do not know it. The programmes are separate, they pay in an order, and there are plans built to coordinate them.

The order of payment
Who pays what, and when
Dual eligibility is not two insurances arguing. It is a defined sequence.
Medicare pays first
For a service both programmes cover, Medicare is the primary payer. The claim goes there first, and it pays its share exactly as it would for anyone else.
Medicaid picks up what is left
Depending on your category, Medicaid pays some or all of the deductible, coinsurance and copays — and in the QMB category, providers are not permitted to bill you for them at all.
Medicaid covers what Medicare will not
Long-term custodial care, non-emergency transport and certain services outside Medicare's scope. This is the part families discover when care needs change.
Medicare Savings Programs
Four programmes, run by the state
These pay Medicare premiums, and sometimes more, for people under the income and asset limits. Georgia and South Carolina each run their own version with their own limits.
| Programme | Full name | What it pays |
|---|---|---|
| QMB | Qualified Medicare Beneficiary | Pays the Part B premium, and the deductibles, coinsurance and copays Medicare leaves. Providers may not bill a QMB member for those amounts. |
| SLMB | Specified Low-Income Medicare Beneficiary | Pays the Part B premium only. A higher income limit than QMB. |
| QI | Qualifying Individual | Pays the Part B premium only. Funded from a limited allocation, so it is granted in order of application each year. |
| QDWI | Qualified Disabled and Working Individual | Pays the Part A premium for certain working people under 65 who lost premium-free Part A when they returned to work. |
Extra Help
The drug subsidy people leave on the table
What it does
The Part D low-income subsidy cuts or removes your drug plan premium and deductible and caps what you pay at the counter. It also removes the Part D late-enrolment penalty.
Who gets it automatically
Anyone with full Medicaid, anyone in a Medicare Savings Program, and anyone receiving Supplemental Security Income is deemed eligible without applying.
Who has to apply
Everyone else who is close to the limits. Applications go to the Social Security Administration, are free, and can be made at any time of year.
Why it goes unclaimed
Because the letters are easy to mistake for advertising. If you are close to the limits, apply anyway — the assessment costs you nothing and the decision explains itself.
D-SNP
Plans built for people with both
A Dual Eligible Special Needs Plan is a Medicare Advantage plan restricted to dual eligible members, with care coordination between the two programmes built in.
C-SNP — Chronic Condition SNP
For people with a qualifying severe or disabling chronic condition — diabetes, chronic heart failure, COPD, end-stage renal disease and others. The formulary, the network and the care team are built around that one condition.
D-SNP — Dual Eligible SNP
For people who have both Medicare and Medicaid. The two programmes are coordinated by one plan, and Medicaid usually picks up the cost sharing Medicare leaves behind.
I-SNP — Institutional SNP
For people who live in a nursing facility, or need that level of care at home, for 90 days or more. Care is delivered where the member already lives.
- Membership is verified against your Medicaid status, so a change in that status changes your plan options.
- Not every county has a D-SNP. Availability is checked county by county, the same as any Advantage plan.
Dual eligibility
Questions about having both
Yes. People with both are called dual eligible, and there is a whole category of Medicare Advantage plan — the D-SNP — designed for them. Having both usually means very low out-of-pocket costs, because Medicaid covers the cost sharing Medicare leaves behind.
It helps it. When a programme pays your Part B premium, that premium stops being deducted from your monthly Social Security payment, so the deposit goes up. It is not a loan and it is not recovered from the benefit.
Yes, and with Extra Help it usually costs little or nothing. If you do not choose one, you may be assigned to a benchmark plan automatically — which is fine until you find your own medicines are not well covered by it. Choosing beats being assigned.
Losing Medicaid or Extra Help opens a Special Enrolment Period, so you can change plans rather than being stranded in one designed for dual eligibility. Tell us when the notice arrives, not when the plan stops working.
Only skilled nursing care, only after a qualifying three-day inpatient hospital stay, and only up to 100 days with coinsurance of $217 a day from day 21 — a sample 2026 figure. Long-term custodial care is not a Medicare benefit at all. Medicaid is the programme that covers it, subject to its own income and asset rules.
Not sure whether you qualify? Ask anyway.
The limits change every year and the rules on what counts as an asset surprise people in both directions. Ten minutes on the phone settles it, and the application costs nothing.
