Medicaid vs. Medicare: What’s the Difference?

Many Americans confuse Medicaid and Medicare, two government-run health programs that sound similar but serve very different purposes. In 2025, understanding the differences between these two programs is more important than ever, especially with rising healthcare costs and evolving coverage rules.

This guide breaks down everything you need to know about Medicaid and Medicare—who qualifies, what each program covers, how much they cost, and how they may overlap.

Medicare: Federal Health Insurance for Seniors and Certain Disabled Individuals

Medicare is a federal health insurance program primarily for:

• People aged 65 or older
• Individuals under 65 with certain disabilities (e.g., receiving Social Security Disability Insurance for 24 months)
• People with End-Stage Renal Disease (ESRD) or ALS

Medicare Has Four Parts:

• Part A: Hospital Insurance – covers inpatient hospital stays, skilled nursing facility care, hospice, and some home health services
• Part B: Medical Insurance – covers doctor visits, outpatient care, preventive services, and some home health services
• Part C: Medicare Advantage – an alternative to Original Medicare offered by private insurers that bundles Parts A, B, and usually Part D
• Part D: Prescription Drug Coverage – helps pay for prescription medications

Costs for Medicare (2025):

• Part A: Usually premium-free if you or your spouse paid Medicare taxes for at least 10 years
• Part B: Monthly premium of about $174.70 in 2025 (varies based on income)
• Deductibles and coinsurance: Apply for both Parts A and B
• Part C and D: Costs vary depending on the plan

Medicaid: State and Federal Health Coverage for Low-Income Americans

Medicaid is a joint federal and state program that provides health coverage for:

• Low-income individuals and families
• Children (CHIP and Medicaid)
• Pregnant women
• Seniors needing long-term care
• People with disabilities

Each state runs its own Medicaid program with specific eligibility rules, income limits, and coverage options, but they must meet federal guidelines.

Eligibility Depends On:

• Income (based on Federal Poverty Level, or FPL)
• Household size
• Age and disability status
• State-specific requirements (e.g., Medicaid expansion states offer broader coverage)

Coverage Includes:

• Hospital and doctor visits
• Preventive care and screenings
• Mental health services
• Maternity and newborn care
• Prescription drugs
• Long-term care (nursing homes, personal care)
• Dental and vision (for children and sometimes adults)

Costs for Medicaid:

• Premiums: Usually none for most groups
• Copays: Minimal or none
• Out-of-pocket costs: Much lower than Medicare or private insurance

Can You Have Both Medicare and Medicaid?

Yes. If you qualify for both, you're considered “dual eligible.”

As a dual eligible individual:

• Medicare covers primary care, hospital services, and prescriptions (via Part D)
• Medicaid covers copays, deductibles, long-term care, and other services not paid by Medicare
• You may be automatically enrolled in a Medicare Savings Program or Special Needs Plan (SNP)

How to Apply

For Medicare:

• Visit ssa.gov to apply for Medicare online
• Apply during your Initial Enrollment Period (3 months before and after your 65th birthday)
• Or during Medicare General or Special Enrollment Periods

For Medicaid:

• Apply via your state Medicaid office or Healthcare.gov
• Eligibility is based on income, and verification may be required annually
• Enrollment is open year-round

Which One Should You Use?

You don’t choose between Medicare or Medicaid—they serve different roles. If you’re over 65 or disabled, you’ll use Medicare. If you have low income, you might also qualify for Medicaid, offering extra support.

FAQs

Can I lose Medicaid if my income increases?

Yes, Medicaid eligibility is income-based. If your income rises above your state’s threshold, you could lose coverage, though transition assistance or ACA marketplace plans may be available.

Does Medicare cover nursing homes?

Only short-term skilled nursing care after hospitalization. Medicaid covers long-term care for eligible individuals.

Is dental care included?

Medicare generally doesn’t cover dental; some Advantage plans do. Medicaid often covers dental for children, and sometimes adults, depending on the state.

Conclusion

Understanding the distinction between Medicare and Medicaid is crucial for making informed decisions about your healthcare coverage. Medicare is a federal program for seniors and certain disabled individuals, while Medicaid is state-administered and supports low-income Americans of all ages.

If you're eligible for both, you can maximize coverage and reduce out-of-pocket costs. Be sure to apply on time, compare plans, and take full advantage of the benefits each program offers in 2025.
