My mom has both Medicare and Medicaid. What does being dual eligible actually change?
Last reviewed 2026-07-31
Having both means the two programs work together. Medicare stays the main health coverage. Through a Medicare Savings Program, a state may pay Part A and Part B premiums, and sometimes deductibles and copays. People in the QMB group may not be billed for Medicare cost sharing. The state decides which program fits.
What happened
Your mom, or you, now has two cards. One is Medicare. One is Medicaid. Bills and letters come from both sides. It is not clear who pays what. People with both are called dual eligible.
What usually applies
Medicare stays the main coverage for doctors, hospitals, and drugs. Medicaid fills gaps that Medicare leaves. A Medicare Savings Program is the piece that pays premiums. Some of those programs also pay deductibles, copays, and coinsurance. The QMB group has the strongest billing shield. Federal law bars providers from billing people in that group for Medicare cost sharing. There are also health plans built for people with both. They are called D-SNPs. The state decides which savings program fits each person.
“Get help from your state paying your Medicare Part A (Hospital Insurance) and Part B (Medical Insurance) premiums through a Medicare Savings Program. If you qualify, Medicare Savings Programs might also pay your Part A and Part B deductibles, coinsurance, and copayments.”
“Federal law prohibits Medicare providers and suppliers, including pharmacies, from billing individuals in the QMB group for Medicare cost sharing. Medicare beneficiaries enrolled in the QMB group have no legal obligation to pay Part A or Part B deductibles, coinsurance, or copayments for any Medicare-covered items and services.”
“The Bipartisan Budget Act (BBA) of 2018 permanently authorized Medicare Advantage Dual Eligible Special Needs Plans (D-SNPs), strengthened Medicare-Medicaid integration requirements”
“You’ll apply for Medicare Savings Programs through your state. When you apply, your state determines which program(s) you qualify for. Even if you don’t think you qualify, you should still apply.”
What to do
- 1
Find out which savings program she is in
Ask the state Medicaid office by name: QMB, SLMB, QI, or QDWI. Each one pays for different things.
- 2
Show both cards at every visit
Bring the Medicare card and the Medicaid or QMB card. That tells the office how to bill.
- 3
Push back on bills for Medicare copays
People in the QMB group may not be billed for Medicare cost sharing. Send the office proof of that status.
- 4
Ask whether a plan for both is offered
Some areas have D-SNP plans that join Medicare and Medicaid. Ask what is offered near her.
If a provider keeps billing her for Medicare copays, call 1-800-MEDICARE and the state Medicaid office. Keep the bills. SHIP counselors and your local 211 line give free help. If the state says no to a savings program, its letter tells you how to ask for a fair hearing.
