Dual Eligible Medicare and Medicaid
A person who qualifies for both Medicare and Medicaid is commonly called dual eligible or dually eligible. Medicare and Medicaid remain separate programs, but Medicaid can help eligible people with Medicare costs and can provide benefits that Medicare does not cover.
Dual eligibility is not one single benefit level. Your coverage depends on your Medicare status, Medicaid eligibility category, state rules, and the plan options available where you live.
What does dual eligible mean?
A dually eligible person has Medicare and also qualifies for Medicaid benefits or a Medicaid-administered Medicare Savings Program category.
Some people receive full Medicaid benefits. Others receive more limited assistance with Medicare premiums or cost sharing.
Because these categories are different, two people who both say they have "Medicare and Medicaid" may have different benefits.
Full-benefit and partial-benefit dual eligibility
CMS recognizes multiple dual-eligibility categories.
At a high level:
- Full-benefit dual eligibility generally means the person has Medicare and qualifies for a broader Medicaid benefit package.
- Partial-benefit dual eligibility generally means Medicaid assistance is limited to certain Medicare costs through a Medicare Savings Program.
Programs and categories include QMB, SLMB, QI, and QDWI, along with full-benefit Medicaid combinations.
Your state Medicaid agency determines your Medicaid eligibility category.
How Medicare and Medicaid work together
Medicare covers Medicare-covered services under Medicare rules. Medicaid can help eligible beneficiaries with Medicare premiums and cost sharing and can cover certain additional services, depending on the state and eligibility category.
Medicaid benefits can include services Medicare does not generally cover, including certain long-term services and supports.
Do not assume Medicaid will pay every cost Medicare leaves behind. The result depends on your specific eligibility.
Extra Help for prescription drugs
People with full-benefit Medicaid and people in certain Medicare Savings Programs automatically qualify for Extra Help with Medicare Part D costs.
Extra Help can reduce Part D premiums, deductibles, and prescription cost sharing.
What is a Dual Eligible Special Needs Plan?
A Dual Eligible Special Needs Plan, or D-SNP, is a Medicare Advantage Special Needs Plan designed for people who meet the plan’s Medicare and Medicaid eligibility requirements.
D-SNPs must include Medicare Part D prescription drug coverage.
A D-SNP may coordinate Medicare and Medicaid benefits, but the exact model, network, benefits, and eligibility requirements vary by plan and state.
Not every D-SNP is available to every dual-eligible person
To join a D-SNP, you generally must:
- have Medicare Part A and Part B;
- live in the plan’s service area; and
- meet the plan’s Medicaid eligibility requirements.
Plan availability varies by location. A plan may be designed for specific dual-eligibility categories.
Provider networks and drug coverage
D-SNPs are Medicare Advantage plans and can use HMO or PPO structures.
Before enrolling, check:
- your doctors and hospitals;
- specialist access;
- referrals;
- prior authorization;
- prescription formulary;
- pharmacy network;
- Medicaid coordination; and
- how the plan handles benefits you use.
Dual eligibility and Medicare Savings Programs
Medicare Savings Programs can help with Part A or Part B costs depending on the program.
QMB provides the broadest Medicare cost-sharing protections among the primary MSP categories. SLMB and QI generally focus on the Part B premium. QDWI can help eligible working people with disabilities pay the Part A premium.
Eligibility rules and state administration matter.
Enrollment opportunities
People with Medicaid or Extra Help may qualify for Special Enrollment Periods that allow Medicare plan changes outside the standard annual enrollment window.
The available action and timing depend on current Medicare rules and your circumstances. Verify the current Special Enrollment Period before changing coverage.
