What Is Full Dual Eligibility vs. Partial Dual Eligibility?

Did you know you can get help from Medicare and Medicaid at the same time? When you qualify for both programs, you’re considered dual eligible. About 12 million Americans fall into this category.¹ 

Having both Medicare and Medicaid can lower your health care costs, which is important when you’re on a low or fixed income. It can also give you access to extra benefits like personal care and transportation. Depending on your coverage, you may also have a care coordinator who can help you understand your benefits, schedule appointments, find providers, and access needed services.

But not all dual-eligible beneficiaries receive the same level of support. Your coverage depends partly on whether you have full or partial dual eligibility. Knowing the differences can help you understand which services are covered and how much help you may get with Medicare costs. 

Full vs. Partial Dual Eligibility: A Comparison

To sum it up: If you’re fully dual-eligible, you receive more coverage with fewer costs. If you’re partially dual-eligible, you still get help with Medicare costs—even if you don’t qualify for full Medicaid.

What is full dual eligibility?

If you are fully dual-eligible, you qualify for both Medicare and the full range of Medicaid benefits in your state. This means you get comprehensive coverage with little or no out-of-pocket costs. Most dual-eligible beneficiaries (75%) fall into the full-benefit category.¹

The benefits of full dual eligibility include:

• Cost-sharing assistance: Medicaid pays your Medicare premiums for both Part A (Hospital Insurance) and Part B (Medical Insurance), saving you money each month. It covers deductibles, copayments, and coinsurance, too—so you’re not stuck with surprise health care bills. As a full dual-eligible, you also qualify for the Part D Low-Income Subsidy (LIS/Extra Help). Extra Help can save you thousands on prescriptions each year. In 2026, most people who qualify will pay no premiums or deductibles for their drug plan and are not subject to the Part D late enrollment penalty.
• Expanded services: In many states, fully dual-eligible people receive extra Medicaid services that Medicare doesn’t cover. One important benefit is long-term nursing home care; Medicaid covers 100% of these costs for people who qualify. It may also cover services such as:
  • Home care
  • Dental, vision, and hearing care
  • Physical, speech, and occupational therapy
  • Prescription drugs
  • Prosthetics
  • Case management
  • Private-duty nursing services
  • Transportation to non-emergency medical appointments

Who qualifies for full dual-eligible benefits?

To get full dual eligibility, you must first be enrolled in Medicare. You must also meet the requirements of one of several mandatory or income-based optional eligibility pathways.

These include:

• Supplemental Security Income (SSI)
• Medically Needy / Spend-Down programs
• Long-term services and supports (LTSS)
• Aged, Blind, and Disabled (ABD) Medicaid
• "Buy In" programs for working people with disabilities

Most dual-eligible adults are enrolled in Medicaid through mandatory eligibility pathways such as SSI. This means if you receive SSI benefits, you automatically qualify for Medicaid.

What is partial dual eligibility?

Some people qualify for partial dual eligibility. They get help with Medicare out-of-pocket costs, but do not qualify for full Medicaid benefits that include long-term care, dental care, and transportation. Compared to full dual-eligible benefits, a smaller number (25%) of beneficiaries qualify for partial benefits.¹

Most partially dual-eligible people qualify for Medicaid help through the Medicare Savings Programs (MSPs). Eligibility for MSPs depends on your income and asset levels, which are a bit more flexible than those for full Medicaid.

The benefits of partial dual eligibility include:

• Help paying Medicare Part A and/or Part B premiums
• May cover deductibles, coinsurance, and copays (depending on the category)

People with partial dual eligibility fall into one of four categories:

1. Qualified Medicare Beneficiary (QMB): Covers Medicare premiums, deductibles, coinsurance, and copays
2. Specified Low-Income Medicare Beneficiary (SLMB): Helps pay Part B premiums only
3. Qualifying Individual (QI): Similar to SLMB, but with slightly higher income limits
4. Qualified Disabled and Working Individual (QDWI): Helps with Medicare Part A premiums for some people who have a disability but have returned to work (and have lost their premium-free Part A coverage)

How do I know if I am dual eligible? Do I qualify for full or partial benefits?

Here are a few ways to find out your eligibility and get help securing your benefits:

• Visit HealthCare.gov: Answer a few questions to check if you qualify for Medicaid based on your income.
• Contact your state Medicaid agency: They can tell you whether you qualify for full or partial benefits and walk you through the Medicaid application process. Eligibility for Medicare and Medicaid are handled and determined separately. Find your local Medicaid agency here.
• Talk to a SHIP counselor: State Health Insurance Assistance Programs (SHIPs) offer free, 100% unbiased advice to older adults and people with disabilities—including those who are dual eligible. A counselor can help you understand all the benefits you qualify for and how to apply to each program. They can also explain your dual-eligible coverage options. For example, a person who is fully dual eligible may qualify for a Dual Special Needs plan (D-SNP), which is designed to coordinate Medicare and Medicaid benefits.

Dual eligibility can be a healthy-aging game changer if you’re an older adult with limited income, said Ryan Ramsey, NCOA Associate Director of Health Coverage and Benefits. “It brings Medicare and Medicaid together to provide more complete coverage, lower health care costs, and access to vital services like long-term care and home health care. For many people, that means being able to get the care and support they need with less financial stress.”

Since navigating both sets of benefits can be complex, don’t be afraid to ask for assistance. With a bit of guidance, you can take full advantage of the programs designed to keep your care affordable—and your health on track.

Frequently asked questions (FAQ)

What is the difference between full and partial dual eligibility?
Full-benefit dual-eligible beneficiaries qualify for complete Medicaid coverage in addition to Medicare. Partial-benefit dual-eligible beneficiaries qualify only for help with certain Medicare costs through a Medicare Savings Program (MSP). Eligibility rules and benefits vary by state.

What benefits do full-benefit dual-eligible beneficiaries receive?
Full-benefit dual-eligible beneficiaries get Medicare-covered services plus full Medicaid benefits. Medicaid may help pay Medicare premiums and out-of-pocket costs and cover services Medicare typically does not cover. This includes long-term care, personal care, non-emergency medical transportation, and some dental and vision care. The specific benefits provided can be different from state to state.

Does partial dual eligibility help pay Medicare premiums and out-of-pocket costs?
Yes. Partial dual eligibility provides financial assistance through a Medicare Savings Program (MSP). Depending on the program, Medicaid may pay your Medicare Part A or Part B premiums and, in some cases, deductibles, coinsurance, and copayments. Partial-benefit beneficiaries don’t receive full Medicaid health coverage.
