Medicare vs. Medicaid: what's the difference?

These two programs are confused constantly, and the confusion is expensive — because in long-term care they do almost opposite jobs. The short version: Medicare is health insurance you earn by age; Medicaid is a needs-based program that actually pays for long-term care.

Medicare

Medicare is federal health insurance for people 65+ (and some younger people with disabilities), regardless of income. It covers hospitals, doctors, and drugs — and short rehab, but not long-term custodial care. You paid into it through payroll taxes; it’s an earned benefit.

Medicaid

Medicaid is a joint federal-state program for people with low income and few assets. It’s the largest payer of long-term care in the country — it covers nursing-home care, and often assisted living through waivers, for those who qualify. Qualifying usually means spending down assets to a low limit, with a five-year look-back on transfers.

Dual eligibility

Many older adults have both — “dual eligibles.” Medicare pays first for medical care; Medicaid fills gaps and covers the long-term care Medicare won’t. Programs like PACE are built for exactly this group and can be nearly free for them.

Why it matters for your plan

The practical takeaway: don’t count on Medicare for long-term care — it isn’t there for it. Plan to self-fund, insure, or spend down to Medicaid. The spend-down estimator shows how long private funds last, and your state’s Medicaid rules spell out the limits.
