Key Takeaways
Understand the differences between Medicare and Medicaid for senior care. Learn what is covered, eligibility requirements, and how to apply.
One of the most common sources of confusion for families navigating senior care is understanding the difference between Medicare and Medicaid. While both are government-sponsored healthcare programs, they serve different purposes, have different eligibility requirements, and cover different aspects of long-term care.
1. What is Medicare?
Medicare is a federal health insurance program primarily for people aged 65 and older, regardless of income. It is divided into several parts:
- Part A (Hospital Insurance): Covers inpatient hospital stays, care in a skilled nursing facility, hospice care, and some home health care.
- Part B (Medical Insurance): Covers certain doctors' services, outpatient care, medical supplies, and preventive services.
- Part D (Prescription Drug Coverage): Helps cover the cost of prescription drugs.
The Medicare Catch
Medicare does not pay for long-term "custodial care" (e.g., help with bathing, dressing, and eating) if that is the only care you need. Original Medicare generally covers only short-term skilled nursing care after a qualifying inpatient hospital stay; Medicare Advantage plans may have different rules, so check your specific plan.
2. What is Medicaid?
Medicaid is a joint federal and state program that helps with medical costs for some people with limited income and resources. Unlike Medicare, Medicaid does cover long-term custodial care in nursing facilities for eligible beneficiaries. In some states, Medicaid waiver or home- and community-based services (HCBS) programs may also help pay for certain care services in assisted living or at home — but which services are covered, waitlists, and room-and-board rules vary significantly by state, and federal Medicaid generally does not pay for room and board outside a nursing facility.
Medicaid Eligibility
Eligibility depends on income and assets, but also on non-financial criteria (state residency, citizenship or qualified immigration status, and category). For long-term care specifically, most states also require a separate functional or level-of-care assessment — meeting the income limit alone is not enough. Limits and rules vary by state. Many seniors who initially do not qualify eventually "spend down" their assets paying for care until they reach the eligibility threshold.
3. The Key Differences Summary
| Feature | Medicare | Medicaid |
|---|---|---|
| Eligibility | Age 65+ or certain disabilities (income not a factor) | Low income and limited assets + functional need (varies by state) |
| Long-Term Custodial Care | No | Yes in nursing facilities; assisted-living or in-home help only via state waiver/HCBS programs (varies by state) |
| Program Administration | Federal only | Federal and State joint |
4. How to Apply
To apply for Medicare, visit the official Social Security website or your local Social Security office. For Medicaid, you must apply through your state's Medicaid agency. Because Medicaid rules are complex and state-specific, consulting with your State Health Insurance Assistance Program (SHIP), an elder-law attorney, or a Medicaid planner is highly recommended.

Before making coverage or spend-down decisions, confirm details with Medicare.gov, your state Medicaid agency, your SHIP, and an elder-law attorney or Medicaid planner.
