How to Qualify for Both Medicare and Medicaid

Your parent is on Medicare but struggling to cover the premiums, copays, and prescription costs—let alone the long-term care they're starting to need. Qualifying for Medicaid alongside Medicare can eliminate nearly all out-of-pocket medical costs and open the door to long-term custodial care coverage that Medicare alone doesn't provide.

People enrolled in both programs are called "dual eligibles," and they receive the most comprehensive public health coverage available in the United States. But the qualification process involves two separate systems with different rules, and the level of benefits depends on which category of dual eligibility your parent falls into.

Full vs. Partial Dual Eligibility

Dual eligibility isn't binary—there are two broad categories, and the difference determines what your parent actually receives.

Full-benefit dual eligibles qualify for the complete scope of both Medicare and their state's full Medicaid program. This includes:

• All Medicare-covered services (hospital, doctor, skilled nursing, Part D drugs)
• All Medicaid-covered services (long-term nursing home care, personal care, HCBS waiver programs, dental, vision, transportation)
• Zero cost sharing—no premiums, deductibles, copays, or coinsurance for most services
• Eligibility for Dual Eligible Special Needs Plans (D-SNPs) with monthly enrollment flexibility

Partial-benefit dual eligibles qualify for Medicare Savings Programs (MSPs), which help pay for Medicare costs but do not provide full Medicaid benefits. They receive:

• Help with Medicare Part B premiums (and sometimes Part A)
• QMB enrollees also get protection from all Medicare cost sharing
• Automatic eligibility for Extra Help (Part D Low-Income Subsidy)
• No long-term custodial care coverage, no HCBS waiver access, no Medicaid dental/vision

The critical distinction: if your parent needs nursing home care or extensive home-based personal care, they need full Medicaid—not just a Medicare Savings Program.

Income and Asset Requirements

Medicare Eligibility

Medicare is straightforward: your parent qualifies at age 65 (or earlier with qualifying disability or ESRD). There is no income or asset test for Medicare itself. Most people get Part A premium-free based on their or their spouse's work history.

Medicaid Eligibility (for Full Benefits)

Medicaid is income- and asset-tested, and the rules vary by state. For long-term care Medicaid:

• Income limit: Varies by state. In "income cap" states (Texas, Florida, Ohio, Indiana, and others), gross monthly income cannot exceed 300% of the Federal Benefit Rate—$2,982 in 2026. In "spend-down" states (New York, Illinois, California), there's no hard income cap—excess income is applied toward the cost of care.
• Asset limit: $2,000 for an individual in most states; $17,500 in Illinois; $33,038 in New York; $130,000 in California (2026).
• Home exemption: The primary residence is generally exempt as long as equity is below the state threshold ($752,000 to $1,130,000).

If your parent's income exceeds the cap in an income-cap state, a Qualified Income Trust (Miller Trust) can be established to redirect excess income into a trust account, bringing countable income below the threshold.

Medicare Savings Programs (for Partial Dual Status)

If your parent doesn't qualify for full Medicaid, they may still qualify for an MSP:

• QMB (≤100% FPL): Income below $1,350/month (single) or $1,824/month (married) and assets below $9,950/$14,910 in 2026. Covers Part A premium, Part B premium, and all Medicare cost sharing.
• SLMB (100–120% FPL): Income below $1,616/month (single) or $2,184/month (married). Covers Part B premium only.
• QI (120–135% FPL): Income below $1,816/month (single) or $2,455/month (married). Covers Part B premium only, must reapply annually.

The Application Process

Step 1: File Form SSA-1020

Start with the Social Security Administration. Form SSA-1020 applies for the Part D Low-Income Subsidy (Extra Help) and simultaneously transmits your parent's financial data to the state Medicaid agency for MSP screening. One form, two screenings.

Step 2: Apply for Full Medicaid at the State Level

If your parent's income and assets are low enough for full Medicaid, file directly with your county Department of Social Services, Health and Human Services, or the equivalent state agency. For long-term care Medicaid, you'll need:

• Social Security card and proof of citizenship
• Gross monthly income documentation (Social Security award letter, pension statements)
• Five years of bank statements for all accounts
• Asset documentation (real estate deeds, vehicle titles, life insurance policies, investment accounts)
• Medical documentation of care needs (for HCBS waivers or nursing home level of care)

Processing takes 45 to 90 days. Benefits can be retroactive to the month of application in most states.

Step 3: Enroll in a D-SNP

Once dual eligibility is established, your parent can enroll in a D-SNP during any month (for full duals using the Integrated Care SEP). The D-SNP consolidates Medicare and Medicaid coordination under one plan, assigns a care coordinator, and provides supplemental benefits.

Common Paths to Dual Eligibility

• Already on Medicare, income drops: Social Security benefits decrease, pension ends, or a spouse dies. The surviving parent's income may now fall below Medicaid thresholds.
• Health crisis forces long-term care: A fall, stroke, or dementia progression makes nursing home care necessary. The family applies for Medicaid specifically for long-term care coverage.
• Asset spend-down: The parent's assets are above Medicaid limits, but legal spend-down strategies (paying off debt, home modifications, prepaid funeral) bring them below the threshold.
