CHIP vs. Medicaid: How These Two Health Programs Differ

The Core Difference Between CHIP and Medicaid

CHIP (Children's Health Insurance Program) and Medicaid are both government health insurance programs, but they serve different groups and have different income limits. Medicaid covers low-income adults, children, pregnant people, seniors, and people with disabilities. CHIP covers children in families that earn too much to may have access to for Medicaid but cannot afford private insurance.

The simplest way to think about it: Medicaid is the broader program that covers multiple age groups and situations. CHIP is a narrower program designed specifically for children whose families fall into a middle income range. If your family's income is very low, Medicaid is usually the first program to check. If your income is higher but you still cannot afford insurance for your children, CHIP may be the option.

Key Takeaways

Medicaid covers low-income people of all ages, including adults, children, seniors, and people with disabilities, while CHIP covers only children in families with moderate incomes.
Income limits for CHIP are higher than Medicaid limits, so a family might not may have access to for Medicaid but could may have access to for CHIP.
Both programs cover doctor visits, hospital care, and prescriptions, though the specific benefits and costs vary by state.
Each state runs its own Medicaid and CHIP programs with different rules, so income limits and covered services differ depending on where you live.

Who Each Program Covers

Medicaid covers children, but it also covers adults, pregnant people, seniors over 65, and people with disabilities who meet income requirements. In some states, Medicaid covers adults earning up to a certain percentage of the federal poverty level. The exact income threshold depends on your state and your situation.

CHIP is limited to children under 19 (or sometimes 21, depending on the state). A child qualifies for CHIP if the family's income is above the Medicaid limit but below the CHIP limit. For example, a state might say Medicaid covers children in families earning up to 138% of the federal poverty level, while CHIP covers children in families earning up to 200% or 250% of that level. This means CHIP acts as a bridge for families in the middle.

Income Limits Vary by State

There is no single national income limit for either program. Each state sets its own thresholds within federal guidelines. A family that qualifies for CHIP in one state might not may have access to in another state, and the same applies to Medicaid.

To find your state's specific limits, you need to contact your state's Medicaid or CHIP office directly or visit your state's health department website. Some states have combined their Medicaid and CHIP programs into a single process, while others keep them separate. The fastest way to learn whether your family qualifies is to call your state's program or use the 211 referral service, which can tell you the current income limits and help you understand which program fits your situation.

What Services Each Program Covers

Both Medicaid and CHIP cover essential health services: doctor visits, hospital care, emergency services, prescription medications, and preventive care like vaccinations and screenings. However, the specific services, copayments, and deductibles differ by state and sometimes by which plan you choose within the program.

Medicaid typically covers a broader range of services because it serves more vulnerable populations. For example, Medicaid in many states covers dental care, vision care, and mental health services. CHIP also covers these services in most states, but the details vary. Some states' CHIP programs have small copayments for doctor visits or prescriptions, while others have none. Before you enroll, ask your state program what is covered and what you might pay out of pocket.

How to Find Out Which Program Your Family Qualifies For

The first step is to gather your family's recent income information: pay stubs, tax returns, or proof of self-employment income if applicable. Then contact your state's Medicaid or CHIP office. Most states have a single process that screens you for both programs at once, so you do not need to explore separately.

You can also call 211 (available in most areas) and ask for a referral to your state's health insurance program. The staff member can tell you the current income limits, walk you through what documents you need, and explain the next steps. Many states also allow you to start the process online through their health department website. The entire process typically takes two to four weeks from submission to a decision.

Cost Differences Between the Programs

Medicaid is usually free or very low-cost for families who may have access to. Most states charge no monthly premium for Medicaid coverage, though some charge small copayments when you use services.

CHIP programs vary more widely. Some states charge no premium, while others charge a small monthly fee (often $10 to $50 per child per month, depending on family income). CHIP may also have small copayments for doctor visits or prescriptions. These costs are designed to be affordable for families in the moderate-income range, but they are higher than Medicaid's costs. Ask your state program about the exact costs before you enroll so there are no surprises.

What Happens If Your Income Changes

If your family's income increases after you enroll, you may lose coverage or move from one program to another. For example, if you are on Medicaid and your income rises above the Medicaid limit but stays below the CHIP limit, you would move to CHIP. If your income rises above both limits, you would lose both programs.

Most states allow you to keep your coverage for a certain period even if your income changes slightly, to avoid gaps in insurance. Report income changes to your state program as soon as they happen. If you lose coverage, you may be able to buy private insurance through the health insurance marketplace, though that will cost more than Medicaid or CHIP.

Frequently Asked Questions

Can a child be on both Medicaid and CHIP at the same time?

No. A child is enrolled in one program or the other based on family income. If your family qualifies for Medicaid, the child goes on Medicaid. If the family's income is too high for Medicaid but within CHIP limits, the child goes on CHIP.

Do I have to pay back Medicaid or CHIP if my income increases later?

No. These are not loans. If you received benefits while you may have access to, you do not have to repay them if your situation changes. However, you must report income changes so your coverage can be adjusted going forward.

What if my state did not expand Medicaid?

Some states have not expanded Medicaid to cover all low-income adults. In those states, Medicaid may only cover children, pregnant people, seniors, and people with disabilities. CHIP is still available for children in moderate-income families. Contact your state program to learn what Medicaid covers in your state.

Can adults get CHIP coverage?

CHIP is for children only in most states. Adults must look to Medicaid or other programs. A few states have extended CHIP to cover parents, but this is rare. Check with your state program to see if your state is one of them.

How long does CHIP coverage last once I am enrolled?

CHIP coverage is usually renewed once a year. You will receive a notice before your renewal date asking you to confirm your income and family information. As long as you remain within the income limits and submit your renewal on time, your child stays covered.
