Medicaid
Medicaid is a joint federal-state program that provides health coverage to low-income individuals and families. Unlike Medicare, which is primarily age-based, Medicaid is a needs-based program that requires applicants to meet income and asset requirements.
Federal-State Partnership
How Medicaid Works
| Aspect | Federal Role | State Role |
|---|
| Funding | Matches state spending (50-77%) | Pays remaining share |
| Standards | Sets minimum requirements | Can exceed federal minimums |
| Administration | CMS oversight | Day-to-day management |
| Eligibility | Establishes baseline | Can expand coverage |
Federal Matching Rates
| Category | Federal Match (FMAP) |
|---|
| Standard Medicaid | 50-77% (varies by state income) |
| ACA Expansion adults | 90% (permanent since 2020) |
| CHIP | Enhanced rate (varies by state) |
Key Point: Wealthier states receive lower federal matching (minimum 50%), while poorer states receive higher matching (up to 77%). This ensures more equitable funding across states.

Medicaid Spend-Down
What is Spend-Down?
| Aspect | Details |
|---|
| Purpose | Allows over-income individuals to qualify |
| Process | "Spend" excess income on medical bills |
| Works like | Deductible that must be met |
| Period | Usually monthly or semi-annual |
Spend-Down Calculation
| Step | Action |
|---|
| 1 | State determines income limit (Medically Needy level) |
| 2 | Calculate person's monthly income |
| 3 | Subtract income limit from actual income |
| 4 | Difference = monthly spend-down amount |
| 5 | Once medical expenses reach spend-down, Medicaid covers rest |
Example
| Item | Amount |
|---|
| Monthly income | $1,500 |
| Medicaid income limit | $1,000 |
| Spend-down amount | $500 |
| After $500 in medical bills | Medicaid covers remaining expenses |
Exam Tip: Spend-down allows people to qualify for Medicaid even if their income exceeds limits—they must first pay medical expenses equal to the excess income.
