Medicaid and CHIP: The Complete 2026 Expert Review

Roughly 78 million Americans rely on Medicaid or CHIP — more than are covered by Medicare or the ACA Marketplace. 2026 is also the year federal work requirements start rolling out for the first time nationwide. Here’s how eligibility actually works, what’s changing, and how to apply.

What Medicaid and CHIP Actually Are

Medicaid is a joint federal-state health insurance program for low-income adults, children, pregnant women, seniors, and people with disabilities. CHIP (the Children’s Health Insurance Program) is a related program covering children — and in some states, pregnant women — in families that earn too much for Medicaid but too little to comfortably afford private coverage. Both are jointly funded by the federal government and the states, but each state designs and administers its own program within federal rules, which is why eligibility, covered benefits, and even the program’s name (it’s “Medi-Cal” in California, “MassHealth” in Massachusetts, and so on) vary widely from state to state.

Regulation is split: CMS sets the federal framework and approves state programs and waivers, while each state Medicaid agency handles day-to-day eligibility, enrollment, and covered benefits. Most adult and family Medicaid uses MAGI (Modified Adjusted Gross Income) rules with no asset test, while Medicaid for seniors, people with disabilities, and long-term care uses different non-MAGI income and asset rules tied to the SSI Federal Benefit Rate rather than the standard poverty guidelines.

This makes Medicaid structurally different from every other category on this site: it’s the only major coverage type with no premium for most enrollees, guaranteed issue regardless of health history, and eligibility based purely on income and category rather than open enrollment windows. It’s also the only category currently undergoing a major nationwide policy change — federal work requirements — which we cover in detail below. For how Medicaid/CHIP fits alongside the other nine major coverage types, see our complete guide to the types of health insurance in America.

Who It’s For — and Who Should Look Elsewhere

• The low-income adult in an expansion state. If you’re under 65 and your household income is at or below 138% of the federal poverty level (about $22,025/year for a single person in 2026), you likely qualify for Medicaid regardless of whether you have children or a disability.
• The parent whose kids don’t qualify for Medicaid but can’t afford private coverage. CHIP typically covers children up to 200%–300%+ FPL depending on the state, with premiums (if any) far below private insurance.
• The pregnant person with limited income. Nearly every state covers pregnancy-related Medicaid at a higher income threshold than standard adult Medicaid, often extending 12 months postpartum.
• The senior or person with a disability needing long-term care. Medicaid is the primary payer for nursing home and long-term in-home care in the U.S. once assets are spun down to program limits — a very different pathway (non-MAGI, asset-tested) from standard adult Medicaid.
• Who should look elsewhere: higher earners above their state’s threshold, and — starting in 2026–2027 — expansion adults who can’t document 80 hours/month of qualifying work or community activities once their state’s new requirement takes effect (see below). Those groups should compare ACA Marketplace subsidies, which become available starting at 100% FPL.

2026 Market Data, Eligibility & the New Work Requirement

Combined, Medicaid and CHIP cover roughly 78.1 million Americans — about 21% of the population — down from a pandemic-era peak of 94 million but still 9% above pre-pandemic enrollment. For 2026, the federal poverty level is $15,960/year for a single person and $33,000/year for a family of four (higher in Alaska and Hawaii); the Medicaid expansion threshold of 138% FPL works out to roughly $22,025/year single or $45,540/year for a family of four. Forty states plus D.C. have adopted expansion; the remaining ten have significantly narrower adult eligibility, in some cases limiting non-disabled parents to well under 30% FPL and excluding childless adults entirely.

Two prior state pilots offer a preview: Arkansas’s 2018 work-requirement demonstration led to significant coverage loss, largely from reporting-system friction rather than actual non-compliance with the work standard — research cited by housing and health policy groups notes that the large majority of people targeted by these requirements are already working, meaning most coverage loss historically has come from paperwork and verification breakdowns rather than actual ineligibility.

How to Evaluate Your Eligibility (Step-by-Step)

1. Find your state’s Medicaid expansion status first. This determines whether the 138% FPL threshold applies to you as a non-disabled adult, or whether you need a different eligibility category entirely.
2. Calculate your household’s MAGI against your state’s income limit for your specific category (adult, pregnant, child, senior/disabled) — thresholds differ significantly by category even within the same state.
3. Check your state’s CHIP income ceiling separately if you have children — many families qualify for CHIP even when the parents don’t qualify for Medicaid.
4. If you’re an expansion-adult enrollee, find out your state’s work-requirement timeline. Some states may implement ahead of the January 2027 federal deadline; ask specifically what counts as a qualifying activity and how you’ll report it.
5. Determine if you qualify for an exemption — pregnancy, medical frailty, caregiving for a young child, or disability status can exempt you from the new work requirement even if you’re otherwise in the expansion adult category.
6. Gather income and identity documentation before applying — most delays and coverage losses stem from documentation and verification issues, not actual ineligibility.
7. Watch your renewal date closely. Renewal cycles are typically every 12 months, but missing a renewal notice is one of the most common reasons people lose coverage they still qualify for.

Key terms to know

• MAGI (Modified Adjusted Gross Income) — the income methodology used for most adult, child, and pregnancy Medicaid categories; no asset test applies.
• Non-MAGI Medicaid — eligibility pathways for seniors, people with disabilities, and long-term care, which do apply asset limits and use the SSI Federal Benefit Rate rather than FPL.
• Community engagement requirement — the federal term for the new 80-hours-per-month work/education/community-service requirement for certain expansion adults.
• Redetermination (renewal) — the periodic process where the state re-verifies you still qualify, typically annually.
• Dual-eligible — someone enrolled in both Medicare and Medicaid, common among low-income seniors.
• 1115 waiver — a federal approval that lets a state test a variation on standard Medicaid rules, including past state-level work-requirement pilots.

Red flags to watch for

• Assuming your coverage is safe without checking your state’s specific work-requirement exemption process once it takes effect in your state.
• Missing a renewal notice — many coverage losses since 2023 have stemmed from address changes or notices going unanswered, not actual ineligibility.
• Not reporting a genuinely exempt status (pregnancy, disability, caregiving) proactively — some states require you to affirmatively claim an exemption rather than applying it automatically.
• Confusing MAGI Medicaid with non-MAGI, asset-tested pathways — applying under the wrong category can result in an inaccurate denial.
• Assuming CHIP and Medicaid have identical income limits for children in your state — they frequently don’t.

How to Apply

Unlike the ACA Marketplace, Medicaid and CHIP have no annual open enrollment period — you can apply at any time of year, and coverage can start retroactively in many states for medical bills incurred shortly before approval. Apply through your state’s Medicaid agency website, in person at a local office, by phone, or through HealthCare.gov (which screens for Medicaid/CHIP eligibility as part of a standard Marketplace application and routes you accordingly). Have on hand: Social Security numbers for household members, proof of income (pay stubs, tax return, or benefit award letters), proof of state residency, and — for non-MAGI categories — documentation of assets and any disability determination.

Cost-Saving Strategies

• Apply even if you’re unsure you qualify. Because thresholds vary so much by category (adult, child, pregnancy, disability) within the same state, it’s common to qualify under one pathway even after being denied under another.
• Check CHIP separately from Medicaid for your children — many parents assume a Medicaid denial means their kids are ineligible too, when CHIP’s income ceiling is often two to three times higher.
• Ask about presumptive eligibility if you’re pregnant or need urgent care — many states can grant temporary coverage immediately while a full application is processed.
• Look into Medicare Savings Programs if you’re a dual-eligible senior — these can cover your Medicare Part B premium and cost-sharing on top of Medicaid.
• Track your renewal date proactively rather than waiting for a notice — a lapse in coverage due to a missed renewal is one of the most preventable and common causes of coverage loss.

Pros and Cons

How It Interacts With Other Coverage

Medicaid coordinates closely with Medicare for “dual-eligible” beneficiaries — low-income seniors and people with disabilities enrolled in both programs, where Medicaid can cover Medicare’s premiums, deductibles, and coinsurance. If your income is too high for Medicaid but below 400% FPL, you generally move to ACA Marketplace subsidized coverage instead — premium tax credits are available starting at 100% FPL, with the gap between Medicaid and Marketplace eligibility being the source of the “coverage gap” problem in non-expansion states for adults between roughly 30–100% FPL who qualify for neither. Medicaid also satisfies the ACA’s individual coverage requirement (though the federal individual mandate penalty itself is currently $0), and having Medicaid disqualifies you from purchasing subsidized Marketplace coverage for the same period, since you can’t be enrolled in both simultaneously for the same benefit.
