Dual Eligibility for Medicare and Medicaid: Requirements and Benefits

Medicaid and Medicare: Dual Eligibility

For millions of Americans, the costs associated with healthcare can be a significant burden, particularly for those with limited incomes or resources.

Fortunately, the federal government offers two programs, Medicare and Medicaid, to alleviate this financial strain.

While Medicare primarily serves individuals aged 65 and older or those with certain disabilities, Medicaid is a needs-based program that provides healthcare coverage to low-income individuals and families.

However, for some, the combined benefits of both programs may be necessary to meet their healthcare needs fully.

This dual eligibility, commonly called “dual eligible,” allows individuals to receive comprehensive coverage from both Medicare and Medicaid, ensuring that their medical expenses are adequately covered.

What is the dual eligibility requirement?

To qualify for dual Medicare and Medicaid coverage, individuals must meet specific requirements set forth by both programs.

These criteria vary from state to state but generally involve meeting certain income and asset thresholds:

  • Income Limits
  • Asset Limits
  • Medicare Enrollment

Income Limits

One of the primary factors in determining dual eligibility is an individual’s income level.

Medicaid, being a needs-based program, has strict income limits that vary based on the state and the applicant’s household size.

In most cases, individuals with incomes below the federal poverty level (FPL) or a percentage of the FPL are eligible for Medicaid coverage.

Asset Limits

In addition to income, Medicaid also considers an individual’s assets when determining eligibility.

Assets can include:

  • Savings accounts
  • Investments
  • Certain properties

The asset limits are determined by each state and can vary from a few thousand dollars to a little bit more.

Medicare Enrollment

People have to be enrolled in Medicare Parts A and B to be deemed dual-eligible.

This enrollment is typically automatic for those receiving Social Security benefits at age 65 or for those who have been receiving disability benefits from Social Security or the Railroad Retirement Board for at least 24 months.

Categories of Dual Eligibility

Within the dual-eligible population, several distinct categories determine the level of assistance an individual receives from Medicaid.

These categories are based on an individual’s income and asset levels, as well as their specific healthcare needs:

Full Benefit, Dual-Eligible

Individuals who fall into this category have incomes and assets that fall below the established thresholds for full Medicaid coverage. As a result, they receive comprehensive benefits from both Medicare and Medicaid, including coverage for premiums, deductibles, coinsurance, and copayments.

Qualified Medicare Beneficiary (QMB)

QMBs are individuals with incomes slightly above the threshold for full Medicaid coverage but below the federal poverty level. In this category, Medicaid covers the costs of:

  • Medicare Part A premiums
  • Medicare Part B premiums
  • Deductibles
  • Coinsurance
  • Copayments

Specified Low-Income Medicare Beneficiary (SLMB) SLMBs have incomes that are higher than the QMB threshold but still below a certain percentage of the federal poverty level.

For these individuals, Medicaid covers only the Medicare Part B premium.

Qualifying Individual (QI)

QIs are individuals with incomes that fall between the SLMB and QMB thresholds. Like SLMBs, Medicaid covers the cost of their Medicare Part B premiums.


Benefits of Dual Eligibility

For those who qualify, the benefits of dual Medicare and Medicaid coverage are substantial, providing a comprehensive safety net for individuals with limited resources.

  • Reduced Out-of-Pocket Costs
  • Expanded Coverage
  • Access to Prescription Drug Coverage

Reduced Out-of-Pocket Costs

One of the primary advantages of dual eligibility is the significant reduction in out-of-pocket costs for healthcare services.

Medicaid covers the costs that Medicare does not, including deductibles, coinsurance, and copayments, depending on the individual’s eligibility category.

Expanded Coverage

In addition to traditional Medicare benefits, dual-eligible individuals may also receive coverage for services not typically covered by Medicare alone. These can include:

  • Long-term care services (nursing home care or home health services)
  • Vision services
  • Dental services
  • Transportation services

Access to Prescription Drug Coverage

Dual-eligible individuals are automatically enrolled in Medicare Part D, the prescription drug coverage plan. However, Medicaid may also provide additional assistance with prescription drug costs, ensuring that necessary medications remain affordable.

Applying for Dual Eligibility

If you believe you may qualify for dual Medicare and Medicaid coverage, the application process typically begins with your state’s Medicaid agency.

Each state has different types of application procedures, but generally, you will need to provide documentation related to:

  • Your income
  • Your assets
  • Your living situation

It’s important to note that the application process can be complex, and seeking assistance from a qualified professional, such as a social worker or a counselor at your local State Health Insurance Assistance Program (SHIP), can be invaluable.

Maintaining Eligibility and Renewing Coverage

Once you have been approved for dual Medicare and Medicaid coverage, it is crucial to understand the requirements for maintaining your eligibility.

This typically involves reporting any changes in:

  • Your income
  • Your assets
  • Your living situation

Additionally, dual eligibility must be renewed periodically, with the frequency depending on your state’s regulations.

Failing to renew your coverage on time could result in a lapse in benefits, which can be particularly detrimental for those with ongoing healthcare needs.


For individuals with limited resources, navigating the complexities of healthcare coverage can be daunting.

Fortunately, the dual Medicare and Medicaid program offers a vital safety net, providing comprehensive coverage and reducing the financial burden of medical expenses.

To take full advantage of dual Medicare and Medicaid and receive necessary healthcare without financial strain, be aware of the eligibility requirements, application process, and renewal requirements.
