Medicaid vs. ACA Marketplace in NC: Which Should You Choose?

Before December 2023, hundreds of thousands of North Carolinians fell into a coverage gap: too much income for the old Medicaid rules, too little to feel secure buying a plan. Medicaid expansion closed that gap, and now the question for many NC residents is which path fits them. This guide compares Medicaid and the ACA marketplace in North Carolina so you can choose with confidence.

Medicaid vs. ACA marketplace in North Carolina: which should you choose?

In North Carolina, the choice is driven mostly by income. If your household earns up to about 138 percent of the federal poverty level, you generally qualify for Medicaid, which has little or no premium. Above that line, you buy a subsidized marketplace plan through HealthCare.gov, where premium tax credits lower your monthly cost. The handoff happens cleanly at that 138 percent line.

This split exists because North Carolina expanded Medicaid effective December 1, 2023. According to NC Medicaid, more than 650,000 residents have enrolled since then. Expansion opened full Medicaid to adults ages 19 to 64 who previously earned too much to qualify but too little to comfortably afford other coverage.

Where is the income line between Medicaid and the marketplace?

The dividing line is about 138 percent of the federal poverty level. Below it, Medicaid. Above it, subsidized marketplace coverage. Here is how that looks by household size for 2026, using the 2025 poverty guidelines.

If your income sits right around the line, it is worth applying through HealthCare.gov, which screens for both Medicaid and marketplace eligibility and routes you to the right program. For a closer look at the income thresholds, see our 2026 ACA income limits guide.

How do Medicaid and marketplace plans compare?

The two programs differ in cost, eligibility, networks, and how you sign up. This side-by-side shows the practical differences for North Carolina residents.

A key advantage of Medicaid is the very low cost of care. A key advantage of the marketplace is broader choice of carriers and provider networks, which matters if you want to keep a specific doctor in Charlotte, Durham, or Asheville.

Can I get a $0-premium marketplace plan in North Carolina?

Yes, many North Carolina residents just above the Medicaid line can find Silver plans with $0 or near-$0 premiums after subsidies. When your income is modest but over 138 percent of FPL, your premium tax credit is large relative to the plan cost, which can wipe out the monthly premium entirely.

For shoppers in that band, a Silver plan is usually the smart pick because it also unlocks cost-sharing reductions, which lower your deductible and out-of-pocket costs. That combination means low monthly cost and lower bills when you actually use care. To confirm your eligibility, see whether you qualify for ACA subsidies in North Carolina.

How do I apply for each in North Carolina?

The application path depends on which side of the income line you are on, but you can start in one place and get sorted automatically.

1. Apply through HealthCare.gov. When you enter your income, the system checks Medicaid eligibility first. If you appear to qualify for Medicaid, it sends your information to the state.
2. Apply through NC ePASS for Medicaid. You can also apply directly at the ePASS online portal run by NC DHHS at medicaid.ncdhhs.gov, by phone, or at your local Department of Social Services.
3. Have your documents ready. You will need income information for everyone in your tax household, plus identity and residency details.
4. Watch your timing. Medicaid enrollment is open year-round. Marketplace enrollment generally requires open enrollment or a qualifying life event such as losing other coverage or moving.

What if my income changes during the year?

Income changes are common, especially for self-employed and hourly workers, and they can move you between programs. If your income rises above the Medicaid line mid-year, you may become eligible for a marketplace plan, which can trigger a special enrollment period. If it falls below the line, you may qualify for Medicaid, which you can enroll in any time.

The important habit is to report changes promptly. Updating your income keeps your coverage and any subsidy accurate, and it prevents surprises at tax time. If you are weighing the marketplace side, check whether you qualify for ACA subsidies in North Carolina to estimate your real cost.

The bottom line on Medicaid vs. marketplace in NC

In North Carolina, the decision is mostly settled by income. Under about 138 percent of the federal poverty level, Medicaid offers the lowest-cost coverage with year-round enrollment. Above that line, a subsidized marketplace plan gives you broader network choice, and many residents just over the line pay little or nothing after subsidies. Apply through HealthCare.gov or NC ePASS, keep your income current, and let the income line point you to the program that fits.
