Insurance Curator Finding affordable health insurance as an adult can feel overwhelming. Premiums keep rising, employer-based plans may not be available, and the open enrollment window is narrow. However, two government programs—Medicaid and CHIP—offer low cost health insurance for adults that qualifies many people who thought they didn’t qualify. Unlike marketplace plans with high deductibles, these programs provide comprehensive coverage at little to no cost.
If you are an adult without employer-sponsored insurance, you may be leaving free or nearly free coverage on the table. This guide breaks down everything you need to know about Medicaid and CHIP eligibility, how to apply, and how to avoid common mistakes.

What Is Low Cost Health Insurance for Adults?
Low cost health insurance for adults refers to coverage that either costs nothing or charges a very low monthly premium, copay, or deductible. Medicaid and the Children’s Health Insurance Program (CHIP) are the two primary public programs offering such coverage. While CHIP is often associated with children, many states also cover pregnant women and, in some cases, parents of eligible children—making it a viable option for low-income adults.
- Medicaid is a joint federal-state program that provides free or low-cost health coverage to millions of Americans, including adults with limited income.
- CHIP is designed for children, but it also covers pregnant women in many states and can sometimes extend to parents or caretaker relatives.
Understanding which program you qualify for depends on your income, household size, state of residence, and whether your state expanded Medicaid under the Affordable Care Act (ACA).
Medicaid: The Cornerstone of Low-Cost Coverage
Medicaid is the single largest source of low cost health insurance for adults in the United States. It covers a wide range of services—doctor visits, hospital stays, preventive care, mental health, prescription drugs, and more—often with zero premium and minimal copays.
Who Is Eligible for Medicaid as an Adult?
Eligibility for adults depends heavily on state decisions. Under the ACA, states were given the option to expand Medicaid to all adults with income up to 138% of the Federal Poverty Level (FPL). As of 2025, 40 states and Washington, D.C. have adopted expansion.
- In expansion states: Single adults earning up to about $20,783 per year (2025 FPL) qualify.
- In non-expansion states: Eligibility is usually limited to parents with very low income (often below 50% FPL), and childless adults may not qualify at all.
Example: A 30-year-old living in Texas (non-expansion) earning $15,000 would likely not qualify for Medicaid. The same person in California would be covered.
What Medicaid Covers
Medicaid benefits are comprehensive. Federal law requires states to cover:
- Inpatient and outpatient hospital services
- Physician services
- Laboratory and X-ray services
- Nursing home and home health care
- Preventive screenings and immunizations
- Mental health and substance use disorder treatment
Many states also offer dental, vision, and transportation benefits. Copays are typically capped at very low amounts (e.g., $3 for a generic drug).
How to Apply for Medicaid
Applications are accepted year-round—there is no limited open enrollment period. You can apply:
- Online via your state’s Medicaid agency or through the Health Insurance Marketplace at HealthCare.gov
- By phone or mail
- In person at a local Department of Social Services or community health center
You will need proof of income, identity, and citizenship or legal status. Most applicants receive a decision within 45 days (or faster if pregnant or disabled).
CHIP: A Low-Cost Option for Parents and Pregnant Women
The Children’s Health Insurance Program (CHIP) was created in 1997 to cover children in families with incomes too high for Medicaid but too low for private insurance. However, CHIP also provides low cost health insurance for adults in two specific categories:
- Pregnant women: Many states cover pregnant women under CHIP with benefits that include prenatal care, labor and delivery, and postpartum care.
- Parents and caretaker relatives: Some states allow parents of children enrolled in CHIP to also get coverage through the program (often called “CHIP for adults” or “Medicaid expansion for parents”).
CHIP Eligibility for Adults
- Income limits vary widely by state. Typically, families with incomes between 138% and up to 300% of FPL may qualify for CHIP for their children. For pregnant women, the income threshold can go even higher—sometimes up to 400% of FPL.
- Status: Adults must be either pregnant or the parent/guardian of a child under 19 who is eligible for CHIP or Medicaid.
Example: A mother with a toddler in Florida earning $35,000 (about 250% FPL) could qualify for CHIP pregnancy coverage, providing full prenatal care with minimal copays.
What CHIP Covers for Adults
When CHIP covers adults, the benefit package is similar to Medicaid, including:
- Doctor visits, hospital care, prescriptions
- Prenatal and postpartum care
- Dental and vision for pregnant women in some states
Premiums are usually low—often $20–$50 per month or less—and copays are capped.
How to Apply for CHIP
Apply the same way as Medicaid—through your state’s CHIP agency or via the Marketplace. Pregnant women should mention their pregnancy during the application to be evaluated for CHIP coverage.
Medicaid vs. CHIP: Eligibility and Cost Comparison
The table below highlights the key differences between the two programs for low cost health insurance for adults.
| Feature | Medicaid | CHIP (for adults) |
|---|---|---|
| Who qualifies | Adults with income ≤ 138% FPL (in expansion states); limited parents in non-expansion | Pregnant women and, in some states, parents of eligible children |
| Income limit | Up to 138% FPL (varies by state) | Typically 138%–400% FPL (state-dependent) |
| Cost | Usually $0 premium; minimal copays | Low premiums (often under $50/month); capped copays |
| Coverage scope | Comprehensive medical, dental, vision, mental health | Similar to Medicaid, including prenatal care |
| Enrollment | Year-round | Year-round |
| Immigrant eligibility | Lawful permanent residents after 5-year waiting period (some exceptions) | Same as Medicaid; pregnant women may qualify even without waiting period |
| State variation | Very large (expansion vs. non-expansion) | Moderate (income limits and adult coverage vary) |
Common Myths About Low Cost Health Insurance for Adults
Myth 1: “I make too much for Medicaid, so I don’t qualify for any help.”
Reality: In expansion states, single adults earning up to about $21,000/year qualify. Even in non-expansion states, pregnant women may qualify for CHIP at higher incomes. Additionally, marketplace subsidies are available for those above the threshold.
Myth 2: “CHIP is only for children.”
Reality: CHIP covers pregnant women in every state, and a handful of states extend coverage to parents. Always check your state’s rules.
Myth 3: “If I have a job, I can’t get Medicaid.”
Reality: Medicaid does not require you to be unemployed. Many working adults with low incomes qualify. The program is based on income, not employment status.
Myth 4: “I’ll lose my coverage if I get a small raise.”
Reality: Medicaid and CHIP have built-in transitions. If your income rises slightly, you may move to a different program (like a subsidized marketplace plan) without a gap in coverage.
Step-by-Step: How to Apply for Medicaid or CHIP
- Check your state’s eligibility – Use the HealthCare.gov screener or visit your state Medicaid website.
- Gather documents – Pay stubs, tax returns, social security numbers, proof of citizenship or legal status.
- Submit an application – Online is fastest. You can also call 1-800-318-2596 (TTY: 1-855-889-4325) for help.
- Wait for a determination – Most states respond within 30–45 days. If you are pregnant, you may get expedited coverage.
- If approved, choose a plan – In many states, you’ll automatically be enrolled in a managed care plan. Review your options if needed.
- Renew annually – Medicaid and CHIP require renewal each year. Keep your contact info updated to avoid losing coverage.

Other Low-Cost Options to Consider
If you do not qualify for Medicaid or CHIP, other low cost health insurance for adults options include:
- Short-term health insurance – Limited duration plans with lower premiums but fewer benefits. They do not cover pre-existing conditions.
- Catastrophic coverage – Available to adults under 30 or those with hardship exemptions. Low premiums but very high deductibles.
For a thorough comparison, read our guide on Low Cost Health Insurance for Adults: Short-term Plans vs. Catastrophic Coverage.
- Marketplace subsidies – If your income is between 100% and 400% FPL, you may qualify for premium tax credits that make private insurance affordable.
- Community health centers – Offer sliding-scale fees based on income, even if you are uninsured.
Expert Insights: Why Understanding the System Matters
Navigating health insurance requires more than just knowing income limits. Many adults miss out on coverage because they assume the process is too complicated or that they don’t “qualify for free stuff.” The reality is that Medicaid and CHIP are designed to serve working families and individuals.
Books like The Price We Pay: What Broke American Health Care–and How to Fix It (rated 4.7 stars) provide context on why the system is broken and how programs like Medicaid are vital safety nets. Understanding the broader landscape helps you advocate for yourself and make informed choices.
Tip: Never skip applying because you think you earn a few dollars too much. The only way to know for sure is to submit an application. Income is evaluated monthly, not annually, in many states.
Frequently Asked Questions
1. Can a childless adult get Medicaid?
Yes, in the 40 expansion states (plus D.C.), any adult under 65 with income up to 138% FPL can qualify. In non-expansion states, childless adults generally cannot get Medicaid unless they are pregnant, disabled, or elderly.
2. Does CHIP cover parents of children who are on CHIP?
In some states, yes. States such as New York, Illinois, and Pennsylvania offer CHIP coverage for parents. Check your state’s specific rules.
3. What is the income limit for Medicaid for a single adult in 2025?
In expansion states, the limit is 138% of the Federal Poverty Level—that’s about $20,783 for a single adult. Non-expansion states have much lower limits (often below $5,000/year for parents).
4. Can I have both Medicaid and another insurance?
Yes, in some cases. If you have employer coverage, Medicaid may still pay for services that your employer plan doesn’t cover (like copays). This is called “secondary coverage.”
5. How long does it take to get approved for Medicaid?
Typically 45 days or less. Pregnant women often receive a decision within 15–30 days. If you apply through the Marketplace, you may get an immediate eligibility determination.
6. Does Medicaid cover dental for adults?
Adult dental coverage is optional for states. About half of states offer comprehensive dental benefits through Medicaid, while others cover only emergency extractions. CHIP often includes dental for children, but adult dental varies.
