Medicare vs Medicaid for Caregivers: What’s the Difference and Which Covers What

Medicare and Medicaid are the two most important programs in the American healthcare and long-term care system — and they are completely different from each other. Confusion between them is one of the most expensive mistakes caregiving families make, because misunderstanding what each covers leads to decisions based on incorrect assumptions.

This guide explains both programs clearly, covers what each actually pays for in the context of serious illness caregiving, and tells you what to do when you reach the limits of both.

The Core Difference in One Sentence

Medicare is health insurance for people 65 and older (and some younger people with disabilities) — it covers medical care but not long-term custodial care. Medicaid is a needs-based public assistance program for people with low income and assets — it covers long-term care including nursing homes and, in many states, home and community-based services.

Medicare: What It Is and What It Covers

Medicare is a federal health insurance program. Most Americans qualify at age 65. Some people under 65 qualify based on disability status (after 24 months of receiving Social Security Disability Insurance) or specific diagnoses like ALS (immediately upon diagnosis) or end-stage renal disease.

Medicare has four main parts:

Part A — Hospital Insurance. Covers inpatient hospital care, skilled nursing facility care following a qualifying hospital stay, some home health care, and hospice care. Most people pay no premium for Part A if they or their spouse paid Medicare taxes while working.

What caregivers need to know: Medicare Part A covers skilled nursing facility (SNF) care after a qualifying 3-day inpatient hospital stay — but only for a limited time and only for skilled services (physical therapy, wound care, IV medications). It does NOT cover ongoing custodial care (help with bathing, dressing, eating). The SNF benefit covers up to 100 days per benefit period, with significant cost-sharing after day 20.

Part B — Medical Insurance. Covers outpatient services: doctor visits, preventive care, medical equipment, mental health services, physical and occupational therapy. Requires a monthly premium ($174.70 in 2024, income-adjusted).

Part C — Medicare Advantage. Private insurance plans that combine Part A and Part B coverage, often with additional benefits. Plans vary significantly by provider and region.

Part D — Prescription Drug Coverage. Prescription drug insurance, available through standalone plans or included in Medicare Advantage. Requires a separate premium.

What Medicare Does NOT Cover — The Critical Gap

Medicare does not cover what most families actually need as serious illness progresses: ongoing custodial care. This includes:

• Assisted living facilities (regardless of how medically necessary)
• Memory care facilities
• Long-term nursing home care beyond the skilled period
• In-home custodial care (daily help with bathing, dressing, meals, supervision)
• Adult day care programs (in most cases)

This gap is the single most important thing for caregiving families to understand. When families assume Medicare will cover the ongoing cost of care — and discover it won’t — the financial impact can be devastating.

Medicaid: What It Is and What It Covers

Medicaid is a joint federal-state program that provides health coverage to people with low income and assets. Unlike Medicare, Medicaid is means-tested — eligibility is based on financial need, not age or work history.

Each state runs its own Medicaid program within federal guidelines, which means coverage, eligibility rules, and the application process vary by state. This is important — Medicaid in New York is meaningfully different from Medicaid in Texas.

What Medicaid covers that Medicare doesn’t:

Medicaid is the primary public payer for long-term care in the United States. It covers:

• Nursing home care (skilled nursing facilities) on an indefinite basis for eligible individuals
• In many states, home and community-based services (HCBS) through Medicaid waivers — including in-home personal care, adult day programs, and sometimes assisted living
• Memory care in some states through HCBS waivers

Medicaid financial eligibility:

For a single person, most states require assets below $2,000 to qualify for Medicaid long-term care coverage. For married couples, the rules are more generous — the community spouse (the one not in a facility) can typically retain significantly more assets under Medicaid’s spousal protection provisions.

Income rules vary by state. In some states, income above a certain level must be “spent down” to qualify. Others have income trusts (called Miller Trusts or Qualified Income Trusts) that allow people with higher income to still qualify.

The spend-down and planning:

The path to Medicaid long-term care coverage typically involves depleting assets to the eligibility threshold — through paying for care, paying off debts, or (carefully, with professional guidance) through legal planning strategies. Medicaid has a five-year look-back period that reviews asset transfers. Transfers made within five years of applying may result in a penalty period.

Medicaid planning — working with an elder law attorney to position assets in a way that maximizes what the family can retain while reaching eligibility — is legal and widely practiced. It is not simple, and it needs to be started well before you need Medicaid, not after.

When Both Programs Apply: Dual Eligibility

Some people qualify for both Medicare and Medicaid — they’re called “dual eligibles.” In this situation, Medicare is primary (it pays first) and Medicaid covers costs Medicare doesn’t — including premiums, cost-sharing, and long-term care. Dual eligibility can significantly reduce out-of-pocket costs for families.

What to Do When You’ve Reached the Limits of Both

Even with Medicare and Medicaid, families often face coverage gaps. Here are the additional paths:

Long-term care insurance. If purchased before the illness, may cover assisted living, memory care, or in-home care costs. Review the policy carefully.

Veterans benefits. The VA’s Aid and Attendance pension provides monthly payments to eligible veterans and surviving spouses who need assistance with daily activities. This benefit is frequently overlooked and underutilized.

PACE programs. Program of All-inclusive Care for the Elderly — integrates Medicare and Medicaid services for people who meet nursing home level of care but wish to remain in the community. Not available in all areas.

State-specific programs. Many states have additional programs beyond Medicaid — prescription assistance, waiver programs, caregiver support programs — that fill specific gaps. An elder law attorney or your state’s Area Agency on Aging can help identify these.
