Medicare vs Medicaid Coverage Differences 2026

Full answer: Medicare is a federal health insurance program for people 65 and older, plus those with qualifying disabilities (SSDI after 24 months), End-Stage Renal Disease, or ALS. Medicaid is a joint federal-state program for people with low incomes, covering those at or below 138% of the Federal Poverty Level in the 40 states plus DC that have expanded Medicaid. The programs have different funding, eligibility rules, and benefit scopes: Medicare follows uniform federal rules for all beneficiaries, while Medicaid coverage varies by state. About 12 million Americans are dual-eligible and receive benefits from both programs simultaneously.

Medicare and Medicaid are both government health programs, but they serve different populations, have different funding structures, and cover different services. Confusing the two is easy — they share a name root and both appear on insurance cards. But the rules governing who qualifies, what gets covered, and how costs are shared are distinct in almost every way.

This guide breaks down the key coverage differences between Medicare (Parts A, B, C, D) and Medicaid (mandatory and optional benefits), what each program costs beneficiaries in 2026, and what dual-eligible individuals with both programs can expect.

Coverage Breakdown

Coverage by type
Feature	Medicare	Medicaid
Who administers it	Federal government (CMS)	Federal + each state jointly
Who qualifies	Age 65+, SSDI 24 months, ESRD, ALS	Low-income adults, children, pregnant, disabled (varies by state)
Income requirement	Open eligibility (any income)	Yes — up to 138% FPL in expansion states
Inpatient hospital	Yes (Part A)	Yes (mandatory benefit)
Outpatient / physician visits	Yes (Part B)	Yes (mandatory benefit)
Prescription drugs	Yes (Part D, OOP cap $2,100 in 2026)	Yes (optional but covered in all states)
Long-term care / nursing home	Limited (up to 100 days skilled nursing only)	Yes (largest payer of long-term care)
Dental, vision, hearing	Limited (Advantage plans only; not Original Medicare)	Varies by state (optional Medicaid benefit)
Monthly premium (2026)	Part B: $202.90/mo (standard)	Usually $0 (state funds most costs)

Medicaid coverage scope varies by state. Dental, vision, and hearing are mandatory for children via EPSDT but optional for adults. 10 states have not expanded Medicaid and use pre-ACA income thresholds.

Medicare: Who Qualifies and What It Covers

Medicare is a federal program with uniform national rules. You qualify automatically if you are 65 or older and either you or your spouse has 40 quarters of Social Security work credits (most people get Part A premium-free as a result). Under 65, you qualify if you have received SSDI for 24 consecutive months, have ALS (automatic from the first month of SSDI), or have End-Stage Renal Disease (dialysis or kidney transplant, typically from the first day of the fourth month of dialysis).

Medicare is divided into four parts. Part A covers inpatient hospital stays ($1,736 deductible per benefit period in 2026), skilled nursing facility care (up to 100 days), hospice, and some home health. Part B covers outpatient care, physician visits, preventive services, and durable medical equipment, with a $283 annual deductible and 20% coinsurance after the deductible. Part C (Medicare Advantage) bundles Parts A and B through private plans and often adds dental, vision, and hearing. Part D covers prescription drugs with a $2,100 out-of-pocket cap in 2026.

Part A: Hospital, skilled nursing, hospice, home health
Part B: Outpatient, physician, preventive, DME ($202.90/month premium in 2026)
Part C (Medicare Advantage): Bundles A+B through private plans, often includes extras
Part D: Prescription drugs, $2,100 OOP cap, $35/month insulin cap (IRA 2022)

Medicaid: Who Qualifies and What It Covers

Medicaid is jointly funded and administered by the federal government and each state. Federal law sets floors (mandatory benefits and minimum eligibility rules), but states set their own income thresholds, optional benefits, and program rules above those floors. Under ACA Medicaid expansion, the 40 states plus DC that have expanded cover adults with income at or below 138% of the Federal Poverty Level (about $22,025 for a single person in 2026 based on the 2025 FPL used for Medicaid eligibility). The 10 non-expansion states (AL, FL, GA, KS, MS, SC, TN, TX, WI, WY) use pre-ACA thresholds that are significantly lower.

Federal law mandates a baseline set of Medicaid benefits that all states must cover. Beyond those, states choose which optional benefits to include. Medicaid is the dominant payer for long-term care in the United States, covering nursing home stays and home and community-based services (HCBS) that Medicare does not. Dental, vision, and hearing are mandatory for children through the EPSDT benefit but optional for adults — coverage varies widely by state.

Mandatory: Inpatient hospital, outpatient hospital, physician, lab/X-ray, nursing facility, EPSDT for children, home health, FQHC services
Optional (covered in most or all states): Prescription drugs, dental (adult), vision (adult), physical therapy, HCBS waivers
Long-term care: Medicaid pays for nursing home stays and home-based services indefinitely (Medicare covers only short-term skilled nursing)
Cost-sharing: Most Medicaid beneficiaries pay $0 in premiums, with small or no copays depending on category

The Biggest Coverage Gaps: Where the Programs Differ Most

The most significant practical differences come down to three areas. First, long-term care: Medicare covers skilled nursing only for short-term rehabilitation (up to 100 days after a qualifying hospital stay), while Medicaid covers long-term nursing home stays without a time limit and pays for HCBS waiver services that keep people at home. Second, cost-sharing: Medicare beneficiaries pay premiums ($202.90/month for Part B in 2026), deductibles, and 20% coinsurance with no out-of-pocket maximum on Original Medicare. Medicaid beneficiaries typically pay nothing or very small copays. Third, dental and vision for adults: Original Medicare does not cover these at all, while Medicaid covers adult dental in most states (though scope varies).

Key coverage gaps: Medicare vs Medicaid side-by-side
Service	Medicare (Original)	Medicaid (typical expansion state)
Long-term nursing home	Up to 100 days (skilled only)	Unlimited (if eligible)
Adult dental	Not covered	Covered in most states
Monthly premium	$202.90 Part B (2026)	$0 in most cases
OOP maximum	None on Original Medicare	Very limited cost-sharing
Home and community-based services	Limited home health only	HCBS waivers available in most states

Original Medicare has no annual out-of-pocket maximum. Medicare Advantage plans are required to have an out-of-pocket maximum (MOOP) of up to $9,250 in 2026.

Dual Eligibility: Getting Both Medicare and Medicaid

About 12 million Americans qualify for both Medicare and Medicaid at the same time. These dual-eligible beneficiaries are typically low-income seniors or people with disabilities. Being dual-eligible fills many of Medicare's largest gaps: Medicaid typically pays Medicare premiums, deductibles, and coinsurance (through Medicare Savings Programs), and Medicaid adds benefits that Medicare doesn't cover, like long-term care, adult dental, and vision.

Dual-eligible individuals can enroll in a Dual Eligible Special Needs Plan (D-SNP), a type of Medicare Advantage plan that contracts with both Medicare and the state Medicaid agency to coordinate all benefits in a single plan. D-SNPs come in three integration levels: Coordination-Only (CO), Highly Integrated Dual-Eligible (HIDE), and Fully Integrated Dual-Eligible (FIDE) SNPs. FIDE SNPs provide the most seamless coordination. CMS strengthened D-SNP requirements in 2026 to simplify coverage dispute resolution for dual-eligible beneficiaries.

Medicare Savings Programs: Medicaid pays Medicare Part B premium ($202.90/month), deductibles, and coinsurance for qualifying dual-eligibles
Extra Help (LIS): Dual-eligible individuals automatically qualify for Medicare Part D Extra Help, covering most drug costs
D-SNPs: Special Medicare Advantage plans that coordinate Medicare and Medicaid in one plan

Which Program Should You Apply For?

If you are 65 or older, apply for Medicare first through Social Security (online at ssa.gov or by calling 1-800-772-1213). If your income is low, also check Medicaid eligibility in your state and Extra Help for Part D costs. You can have both. If you are under 65 and have a low income, check Medicaid eligibility — income qualification is assessed based on Modified Adjusted Gross Income (MAGI). If you have a disability but have not yet reached 24 months of SSDI, you will be on Medicaid until Medicare kicks in automatically.

People living in non-expansion states (AL, FL, GA, KS, MS, SC, TN, TX, WI, WY) face a coverage gap: if their income is above the very low pre-ACA Medicaid threshold but below the ACA marketplace subsidy floor (100% FPL, about $15,650 for a single person for 2026 plans), they may not qualify for either Medicaid or subsidized marketplace coverage. If you fall in this gap, federally qualified health centers (FQHCs) provide care on a sliding-fee scale.

Frequently Asked Questions

What is the main difference between Medicare and Medicaid?

Medicare is a federal health insurance program for people 65 and older and those with qualifying disabilities. Eligibility is NOT income-based. Medicaid is a joint federal-state program for low-income individuals. Income is the primary qualifier. A person can have both programs simultaneously — about 12 million Americans are dual-eligible.

Does Medicare or Medicaid cover nursing home care long-term?

Medicaid is the primary payer for long-term nursing home care. Medicare covers skilled nursing facility care for only up to 100 days after a qualifying hospital stay (for rehabilitation, not custodial care). If you need long-term nursing home care and cannot afford it, Medicaid is the program to apply for after spending down assets.

Can I have both Medicare and Medicaid at the same time?

Yes. About 12 million Americans are dual-eligible, meaning they qualify for both Medicare and Medicaid simultaneously. Medicaid typically pays Medicare's premiums, deductibles, and coinsurance through Medicare Savings Programs, making dual eligibility highly valuable. Dual-eligible individuals can enroll in a D-SNP to coordinate both programs in one plan.

Does Medicaid or Medicare have lower costs for beneficiaries?

Medicaid is almost always lower-cost for beneficiaries. Most Medicaid beneficiaries pay $0 in premiums and have very limited copays. Medicare Part B has a $202.90/month standard premium in 2026, plus a $283 annual deductible and 20% coinsurance on covered services. Original Medicare also has no annual out-of-pocket maximum, unlike Medicare Advantage plans (which cap at $9,250 in 2026).

Does Medicare or Medicaid cover dental for adults?

Neither Original Medicare nor Medicaid guarantees adult dental coverage, but Medicaid covers adult dental in most states (as an optional benefit). Original Medicare (Parts A and B) does not cover routine dental at all. Medicare Advantage (Part C) plans often include limited dental as a supplemental benefit. Medicaid's adult dental scope varies widely — some states cover comprehensive dental, others cover only emergency extractions.

Who funds Medicare vs Medicaid?

Medicare is funded primarily through federal payroll taxes (FICA), trust fund income, and beneficiary premiums. It is purely a federal program. Medicaid is jointly funded: the federal government contributes a matching share (FMAP) that ranges from about 50% to over 76% depending on each state's per capita income, and states fund the rest. Wealthier states pay a higher state share.

Does Medicare cover prescription drugs?

Yes. Medicare Part D covers prescription drugs through standalone Part D plans or Medicare Advantage plans with drug coverage. In 2026, Part D has a $2,100 annual out-of-pocket cap. Insulin is capped at $35/month per the Inflation Reduction Act (effective January 2023). Dual-eligible individuals automatically get Extra Help (Low Income Subsidy), which reduces drug costs to near zero.

How do I know if I qualify for Medicare, Medicaid, or both?

Use the CoveredUSA screener at coveredusa.org/screener to check eligibility for Medicare, Medicaid, CHIP, and marketplace plans based on your age, income, household size, and disability status. Medicare eligibility is primarily determined by age (65+) or disability history. Medicaid eligibility is primarily income-based and varies by state. Enrollment in Medicaid is available year-round with no open enrollment period.
