Medicaid and CHIP: How Health Coverage for Families Works

Medicaid and CHIP are the two main public health coverage programs for families with limited income, but the difference between them — and who qualifies for which — isn’t always clear. Here’s a plain-language breakdown.

Family Benefits Club is an independent informational resource. We are not a government agency and do not process Medicaid or CHIP applications — those are handled by your state’s Medicaid agency. Eligibility rules and income limits vary by state and change periodically, so always confirm current details there.

What Medicaid Covers

Medicaid is a joint federal and state program providing health coverage to eligible low-income adults, children, pregnant women, elderly adults, and people with disabilities. Coverage generally includes doctor visits, hospital care, prescription drugs, and preventive care, though exact benefits vary somewhat by state. Many states expanded Medicaid eligibility to cover more low-income adults, so it’s worth checking even if you assumed you wouldn’t qualify.

What CHIP Covers

CHIP specifically covers children in families who earn too much to qualify for Medicaid but still need help affording coverage. In many states, CHIP also covers pregnant women. CHIP plans typically include doctor visits, immunizations, dental and vision care, and hospital care, often for a low or no monthly premium depending on household income.

How Eligibility Generally Works

Both programs base eligibility mainly on household income relative to your state’s limits, which are typically expressed as a percentage of the federal poverty level and adjusted for household size. Because these thresholds change and differ by state, the only reliable way to know if you qualify is to check your state’s specific Medicaid/CHIP agency or apply directly — income estimates from other sources can be outdated or apply to a different state.

How to Apply

• Apply through your state’s Medicaid agency or through the federal Health Insurance Marketplace at healthcare.gov, which will route eligible applicants to Medicaid or CHIP automatically.
• Have income documentation ready — recent pay stubs, tax returns, or benefit award letters — along with Social Security numbers and identification for household members applying.
• Apply even if you’re unsure you qualify. There’s no cost to apply, and eligibility is often broader than people expect, especially for children.
• Know that coverage can sometimes be retroactive, covering medical bills from shortly before your application date in some states — ask your caseworker about this if you have recent medical bills.

After You’re Approved

Once enrolled, you’ll typically choose or be assigned a managed care plan and a primary care provider. Keep your enrollment materials, as they’ll explain how to find in-network doctors and what to do if you need to renew coverage — most states require periodic renewal, and missing a renewal notice is one of the most common reasons families lose coverage unexpectedly.

If You’re Denied or Coverage Lapses

Every state has an appeals process if you believe a Medicaid or CHIP decision was made in error. If your income changes and you no longer qualify, ask about a transition period or about Marketplace plans, which may offer subsidized coverage as an alternative. Our Health Insurance Marketplace Enrollment Checklist covers what to gather if that applies to your household.

Health coverage gaps are stressful, but both programs exist specifically to prevent families from going without care over cost, and applying costs nothing but time.
