Medicare vs Medicaid: What's the Difference for Seniors?

Medicare vs Medicaid: What's the Difference for Seniors?

Medicare and Medicaid are often confused, but they serve very different purposes. Understanding both programs is essential for families navigating senior care, especially since many seniors may qualify for both.

The Basic Difference

Medicare is a federal health insurance program for people 65+ (and some younger people with disabilities). It's based on age and work history, not income.

Medicaid is a joint federal-state assistance program for people with limited income and assets. It's based on financial need, not age.

Medicare at a Glance

#### Who Qualifies

Age 65 or older
Under 65 with certain disabilities (after 24 months of Social Security disability)
Any age with End-Stage Renal Disease or ALS

#### What It Covers

Part A (Hospital): Inpatient hospital, skilled nursing (limited), hospice, some home health
Part B (Medical): Doctor visits, outpatient care, preventive services, medical equipment
Part C (Advantage): Bundled plans from private insurers (includes Parts A & B, often D)
Part D (Drugs): Prescription drug coverage

#### What It Does NOT Cover

Long-term custodial care (the biggest gap for seniors)
Dental, vision, and hearing (traditional Medicare; some Advantage plans do)
Care outside the US (with rare exceptions)
Assisted living room and board

Medicaid at a Glance

#### Who Qualifies

Income below state-specific limits (varies widely)
Assets below limits (typically $2,000 for individuals)
Must be a US citizen or qualified immigrant
Some states have expanded Medicaid with higher income limits

#### What It Covers

Medicaid often covers services Medicare doesn't:

Long-term nursing home care (the primary payer for nursing homes in the US)
Home and community-based services (personal care, adult day programs)
Dental, vision, and hearing (in many states)
Transportation to medical appointments
Prescription drugs

Side-by-Side Comparison

Feature — Medicare — Medicaid

Funded by — Federal — Federal + State

Based on — Age/disability — Financial need

Premiums — Yes (Part B, D) — Little to none

Long-term care — Very limited — Yes

Dental/vision — No (traditional) — Often yes

Enrollment — Must enroll — Must apply

Managed by — CMS (federal) — State agencies

Dual Eligibility: Having Both

Approximately 12 million Americans qualify for both Medicare and Medicaid (called "dual eligibles"). If your loved one has both:

Medicare is the primary payer for most medical services
Medicaid covers what Medicare doesn't — including long-term care, dental, and copays
Medicare Savings Programs through Medicaid can pay Medicare premiums and cost-sharing
Special Needs Plans (SNPs) are Medicare Advantage plans designed specifically for dual eligibles

How to Apply

#### Medicare

Automatic enrollment at 65 if already receiving Social Security
Otherwise, apply through SSA.gov or your local Social Security office
Initial Enrollment Period: 3 months before to 3 months after your 65th birthday

#### Medicaid

Apply through your state Medicaid agency or healthcare.gov
Applications can be submitted online, by phone, by mail, or in person
Processing time varies — typically 30-90 days
May need to provide documentation of income, assets, medical conditions

Common Misconceptions

"Medicare covers nursing home care."

Only for short-term skilled rehabilitation (up to 100 days) after a qualifying hospital stay. It does NOT cover long-term custodial care.

"You have to be completely broke to get Medicaid."

While asset limits are low, certain assets are exempt (primary home, one vehicle, personal belongings). Medicaid planning with an elder law attorney can help protect assets legally.

"Once you're on Medicaid, you lose your home."

Your home is generally exempt while you or your spouse lives there. However, states may seek estate recovery after death.

Action Steps for Families

1. Determine eligibility for both programs

2. Apply for Medicare during the Initial Enrollment Period to avoid penalties

3. Explore Medicaid if your loved one has limited income and assets

4. Consider Medicare Savings Programs if your loved one is near the Medicaid income limit

5. Consult a SHIP counselor for free, unbiased guidance on both programs

6. Talk to an elder law attorney if Medicaid planning is needed

Which one is health insurance and which one is a safety net?

Medicare is federal health insurance earned through work. Eligibility is based on age or disability, not income. The rules are the same in every state.

Medicaid is a joint federal and state program based on need. Each state sets its own income limits, asset limits and covered services, which is why advice from a relative in another state is often wrong.

What does Medicare not cover that families expect it to?

Long-term custodial care, at home or in a facility. This is the big one.
Most dental care, routine eye exams for glasses, and hearing aids.
Homemaker services, meal preparation and 24-hour supervision.
Outpatient prescription drugs, unless the person has Part D.

Medicare will pay for up to 100 days of skilled nursing per benefit period after a qualifying three-midnight inpatient hospital stay, with daily coinsurance after day 20. It will pay for intermittent home health visits when a doctor orders them and the person is homebound. It pays for hospice in full. None of that is the same as daily help at home for years.

What are the four parts of Medicare, in plain terms?

Part A: hospital, skilled nursing after a hospital stay, home health and hospice. No premium for most people.
Part B: doctors, outpatient care, therapy, lab work and durable medical equipment. Monthly premium, annual deductible, then 20 percent coinsurance with no out-of-pocket cap.
Part C, Medicare Advantage: a private plan that replaces A and B, usually bundles drugs, uses a network, and caps out-of-pocket costs.
Part D: outpatient prescription drugs, through a private plan with its own formulary.

A Medigap policy covers the gaps in Original Medicare, including that uncapped 20 percent. Medigap cannot be combined with Medicare Advantage.

Can someone qualify for Medicaid without being poor their whole life?

Yes, and most long-term care Medicaid recipients did not start poor. They spent their savings on care and then qualified.

Medicaid has both a medical test, a state assessment finding a nursing-home level of need, and a financial test with income and asset limits. Spousal protections let the spouse at home keep a share of assets and income. A five-year look-back reviews the previous 60 months of financial records, and gifts in that window create a penalty period.

The legitimate spend-down moves are spending on the applicant's own benefit: the mortgage, medical bills, home repairs, a reliable vehicle, prepaid funeral costs. Gifting money to children is the move that causes the most damage.

Where do you get free, unbiased help?

Call 1-800-MEDICARE and ask for your State Health Insurance Assistance Program. SHIP counselors are trained, free and earn no commission on plans. Ask them about Extra Help for drug costs and Medicare Savings Programs, which can pay the Part B premium outright.

For Medicaid and long-term care planning, see an elder law attorney licensed in your state before moving any money.
