Most people confuse Medicare and Medicaid — and the mistake can cost $100,000+. Medicare covers short-term rehab in a nursing home (up to 100 days). Medicaid covers long-term custodial care (indefinitely). Neither covers everything, and understanding where each stops is critical for financial planning.

Quick answer: Medicare pays for skilled nursing facility stays after a qualifying hospital stay — 100% for days 1–20, $204.50/day copay for days 21–100, and nothing after day 100. Medicaid pays for long-term nursing home care indefinitely but requires you to have less than $2,000 in assets (most states). About 62% of nursing home residents rely on Medicaid. They’re completely different programs with different eligibility, coverage, and purpose.

Medicaid eligible Once assets ≤ $2,000 Medicaid Depleted

The “Observation Status” Trap

Risk Details
Problem Hospital classifies you as “observation” instead of “inpatient”
Impact Your hospital time does NOT count toward the 3-day qualifying stay
Result Medicare will NOT pay for any SNF care afterward
How often About 1 in 4 Medicare hospital stays are observation status
How to check Ask the hospital if you’re admitted as inpatient or observation
Your rights You can request the Medicare Outpatient Observation Notice (MOON)
Appeal You can ask the hospital to change your status to inpatient

When Each Program Is Better

Medicare Is Better When

Situation Why
Short-term rehab after surgery 100% coverage for 20 days, then copay through day 100
Recovery from hip replacement/stroke Skilled therapy covered
Temporary skilled nursing need No asset or income test
You have Medigap C, F, or G Copay for days 21–100 covered

Medicaid Is Better When

Situation Why
Long-term custodial care needed No time limit
Assets depleted Primary program for those who can’t self-pay
Dementia/Alzheimer’s care Covers indefinite custodial care
Can’t qualify for Medicare SNF No hospital stay requirement

Dual Eligibility (Medicare + Medicaid)

Feature Details
Who qualifies Low-income Medicare beneficiaries
How it works Medicare pays first (as primary), Medicaid fills gaps
SNF coverage Medicare covers days 1–100 (Medicaid may cover copay); Medicaid covers after day 100
Advantage No gap in coverage between Medicare and Medicaid
% of nursing home residents ~20% are dual-eligible
Medicare Savings Programs Medicaid pays Medicare premiums, deductibles, copays

Bottom Line

Medicare and Medicaid serve completely different purposes for nursing home care. Medicare is your short-term rehab benefit (up to 100 days after a hospital stay). Medicaid is your long-term care safety net (indefinite, but requires near-poverty). Plan for the gap between them — the self-pay period between Medicare running out and Medicaid eligibility can cost $100,000–$200,000+. Long-term care insurance, savings, or advance Medicaid planning covers this critical gap.
