The Caregiver's Guide to Understanding Medicare vs. Medicaid

Published April 19, 2026 · 5 min read

Your dad needs home health care. Someone told you Medicare covers it. Someone else told you it doesn't. Your sister thinks Medicaid is the same thing. Your dad says he "has the good insurance" but can't tell you which plan he's on. Meanwhile, there's a $5,000/month bill coming and nobody knows who's paying it.

Medicare and Medicaid are two completely different programs that happen to have similar names. Confusing them — or not understanding what each one covers — can cost your family thousands of dollars and months of bureaucratic headaches. Here's the version nobody explained to you clearly the first time.

Medicare: What It Is and What It Covers

Medicare is federal health insurance for people 65 and older (and some younger people with disabilities). If your parent is over 65, they almost certainly have it. It comes in parts, because nothing in government is simple.

Part A (Hospital Insurance): Covers inpatient hospital stays, skilled nursing facility care (with conditions), hospice, and some home health care. Most people don't pay a premium for Part A because they paid into it through payroll taxes during their working years.

Part B (Medical Insurance): Covers doctor visits, outpatient care, preventive services, durable medical equipment (walkers, wheelchairs), and some home health services. The standard Part B premium is about $175/month in 2026, though it's higher for higher-income beneficiaries.

Part C (Medicare Advantage): Private insurance plans that bundle Part A and Part B, often with additional benefits like dental, vision, and prescription drugs. These have their own networks and rules. Our guide on understanding parent insurance covers this in detail.

Part D (Prescription Drug Coverage): Covers outpatient prescription medications. Separate plan with its own premium, deductible, and formulary.

What Medicare does NOT cover — and this is the part that catches families off guard:

• Long-term custodial care (the kind most aging parents need — help with bathing, dressing, meals)
• Assisted living facilities
• Home health aides for non-medical personal care on an ongoing basis
• Most dental, vision, and hearing care under Original Medicare

Medicare will pay for a home health aide — but only if your parent also needs skilled nursing or therapy, was ordered home health by a doctor, and is considered homebound. The aide coverage piggybacks on the skilled service. Once the skilled need ends, the aide coverage ends. This surprises roughly every family I've talked to.

Medicaid: What It Is and What It Covers

Medicaid is a joint federal-state program for people with very low income and assets. Unlike Medicare, which is age-based, Medicaid is need-based. The rules vary by state — sometimes dramatically. Our guide on Medicaid spend-down rules covers this in detail.

What Medicaid covers that Medicare doesn't:

• Long-term nursing home care
• Personal care services at home (in many states)
• Assisted living (in states with Home and Community-Based Services waivers)
• Adult day care programs

This is the program that pays for long-term care when the money runs out. Medicaid is the largest payer of long-term care in the United States. But qualifying is not straightforward.

Income and asset limits for Medicaid vary by state, but generally:

• The applicant's countable assets must be below about $2,000 (some states are higher)
• The primary home is usually exempt — up to a certain equity value — as long as the applicant intends to return or a spouse still lives there
• There's a "look-back period" of 5 years: if your parent gave away money or transferred assets within the past 5 years, it can trigger a penalty period of ineligibility

That look-back period is what makes Medicaid planning so critical — and why families need to think about this years before they need it, not the week Dad runs out of money. Our guide on in-home care costs covers this in detail.

When Your Parent Has Both (Dual Eligibility)

Some people qualify for both Medicare and Medicaid. This is called "dual eligibility" and it's more common than you'd think — about 12 million Americans. If your parent is over 65 with limited income and assets, they may qualify.

When someone has both, Medicaid typically pays Medicare premiums, deductibles, and copays. It also fills in the gaps Medicare leaves — particularly long-term care. This combination provides the most comprehensive coverage available, but getting it requires applying for Medicaid and meeting the financial criteria.

Check with your state's Medicaid office or your local Area Agency on Aging to see if your parent qualifies. The application process is bureaucratic — expect paperwork, documentation of every account and asset, and a wait of 45-90 days for a decision.

What This Means for Your Family Right Now

If your parent needs long-term help — the kind where someone comes every day to help them bathe, eat, and take medications — Medicare probably isn't paying for it. That cost is coming from one of four places: your parent's savings, long-term care insurance (if they bought it), Medicaid (if they qualify), or your family's pockets.

The average American will need some form of long-term care for about 3 years. At $4,500-10,000/month depending on the level, that's $162,000-$360,000. These numbers are why families fracture over caregiving finances. They're not small, and they're not optional.

Talk to an elder law attorney. Not a general lawyer — an elder law attorney who specializes in Medicaid planning. A one-hour consultation ($200-400) can save your family tens of thousands of dollars in mistakes. They'll help you understand what your parent's options are given their specific financial situation and your state's rules.

Insurance isn't exciting. But understanding what's covered and what's not is the difference between a family that plans and a family that panics. Your parent's care shouldn't depend on which sibling Googles fastest. For a side-by-side look at tools that help families coordinate, check our caregiving app comparison guide.
