Medicare vs. Medicaid: what makes them different and when you might have both

The simplest way to hold them apart: Medicare asks how old are you or do you have a qualifying disability, while Medicaid asks what is your income and where do you live.

Medicare has four main parts:

• Part A covers inpatient hospital care, skilled nursing facility (SNF) stays, hospice, and some home health services. Part A is premium-free for people with 40 or more quarters (about 10 years) of Medicare-taxed work. In 2026, the Part A inpatient deductible is $1,736 per benefit period, not per calendar year, so two separate hospitalizations in one year can each trigger it. In 2026, the full Part A buy-in premium is $565 per month for people with fewer than 30 quarters of coverage.
• Part B covers outpatient care, physician visits, preventive services, and durable medical equipment. In 2026, the standard Part B premium is $202.90 per month, and the annual Part B deductible is $283. After the deductible, Medicare pays 80% of the approved amount and the beneficiary pays the remaining 20%, with no annual cap on that 20%.
• Part C (Medicare Advantage) bundles Part A and Part B coverage through a private insurer approved by Medicare, often including Part D drug coverage. In 2026, the federal in-network out-of-pocket maximum (MOOP, the most you pay before the plan covers 100%) cap for Medicare Advantage is $9,250; plans may set lower limits.
• Part D covers prescription drugs. In 2026, out-of-pocket spending on covered Part D drugs is capped at $2,100 for the year, and no Part D plan may set a deductible above $615.

Higher-income beneficiaries pay more through IRMAA (Income-Related Monthly Adjustment Amount), a surcharge applied to both Part B and Part D. In 2026, IRMAA begins above $109,000 in modified adjusted gross income (MAGI) for individuals and $218,000 for joint filers, using a two-year lookback, meaning 2026 premiums are based on 2024 income.

Medicaid does not have a single national design. The federal government sets minimum coverage requirements and matches state spending, but each state administers its own program, sets its own income limits above the federal floor, and decides whether to cover optional benefits such as dental, vision, and long-term services.

Key characteristics:

• Income-based eligibility. The Affordable Care Act expanded Medicaid to adults with incomes up to 138% of the federal poverty level in states that adopted the expansion, though not all states have done so.
• No premium in most cases. Most Medicaid enrollees pay little to nothing in premiums, though some states charge small cost-sharing for certain services.
• Broader long-term care coverage. Medicaid is the primary payer for nursing home care in the United States. Medicare covers skilled nursing only under strict conditions, including a 3-day formal inpatient hospital admission beforehand, and only for a limited period (days 1 to 20 are fully covered; days 21 to 100 require a coinsurance of $217 per day in 2026; after day 100 the beneficiary pays all costs). Medicaid can cover custodial long-term care that Medicare never covers.

Because eligibility rules and benefit details change annually and vary by state, the Extra Help and Medicare Savings Program (MSP) income and asset limits are indexed annually and vary by state. Check current-year values through your state Medicaid agency rather than relying on a single number.

Someone who meets both Medicare's age or disability criteria and Medicaid's income criteria is called a dual-eligible beneficiary. This is more common than many people realize, particularly among older adults with limited retirement income and people on SSDI.

For dual-eligible individuals, the programs coordinate benefits. Medicare generally pays first for covered services, and Medicaid may cover remaining cost-sharing such as premiums, deductibles, and copayments depending on the level of coordination. There are several categories of dual eligibility, ranging from full dual coverage (Medicaid covers nearly all Medicare cost-sharing) to partial categories that cover only the Part B premium.

Dual-eligible beneficiaries may also qualify for the Part D Low Income Subsidy (LIS, also called Extra Help), which reduces or eliminates Part D premiums and cost-sharing. LIS eligibility is tied to income and asset limits that are updated annually.

If you think you or a family member may qualify as dual-eligible, to find out more about coverage, please contact us to discuss plan options.

The two programs were created by the same 1965 legislation and share the same federal administrator (the Centers for Medicare and Medicaid Services, or CMS), but their logic, funding, and day-to-day rules are genuinely distinct. Knowing which program applies to a given need, or whether both apply, is the first step toward using each one effectively.
