Two things decide most South Carolina coverage questions, and neither is the plan you pick. The state uses the federal marketplace, and it never expanded Medicaid. The second one is what catches people, and it turns on the income number you write on the application.

How South Carolina coverage actually works
South Carolina uses HealthCare.gov, the federal marketplace, so the calendar and the website are the familiar ones. The ACA rules apply in full: nobody is declined for health history, nobody pays more for a pre-existing condition, and the subsidy is based on the income you expect for the year rather than what you earned last year. Because South Carolina is on the federal calendar, open enrollment for 2027 coverage runs November 1, 2026 through January 15, 2027. December 15, 2026 is the date that actually matters: it is the last day to pick a plan that starts January 1. Enroll after that and coverage does not begin until February 1. My open enrollment guide covers the rest, including what opens a window outside those dates and the appeal still running against the rule that would have shortened the season.
There is also a private market outside the exchange, and many of its plans aren't ACA plans. Those can ask health questions and decline an applicant, and they enroll year round. For a healthy buyer earning too much to qualify for a subsidy, that is sometimes the better answer. It is a different product with different rules, not the same coverage cheaper, and the private plans vs. the marketplace guide spells out how they differ. I quote both doors side by side.
The one South Carolina thing you should know
South Carolina did not expand Medicaid. That creates a coverage gap, and it is the single most important thing to understand about buying your own insurance here. Earn too little and you can fall below the threshold for a marketplace subsidy while still not qualifying for regular Medicaid. Earn a little more and the subsidy appears. It is the wrong way round, it catches people every year, and I would rather tell you the gap exists than pretend every South Carolinian has a good option.
The practical upshot is that your income estimate is not paperwork, it is the whole decision. If your income is low, seasonal, or hard to predict, talk to me before you conclude you are stuck. Where that number lands changes which door is even open to you.
Networks from the Upstate to the Lowcountry
Whether a plan covers your hospital is a network question, not a brand question. South Carolina networks look different in the Upstate, the Midlands and the Lowcountry, and two plans at the same premium can treat the same hospital completely differently. If your doctor is in Charleston and you live inland, or the other way round, that needs checking before you enroll. It is part of every quote I run.
If you work for yourself, everything in the self-employed guide applies here: the premium deduction, estimating an income that moves, and the marketplace versus private decision.
Questions South Carolinians actually ask
Can an out-of-state broker help me in South Carolina?
Yes. My South Carolina license runs under NPN 22091157. The thing worth asking a broker here is not where they are based but whether they will be straight with you about the coverage gap, because it is the single most consequential thing about buying coverage in this state.
Does South Carolina have its own exchange?
No. South Carolina uses HealthCare.gov, the federal marketplace, so the website and the enrollment calendar are the federal ones.
Did South Carolina expand Medicaid?
No. That is why a coverage gap exists here. Some adults earn too little for a marketplace subsidy and still do not qualify for regular Medicaid. If your income is low or irregular, talk to someone before you assume you are out of options.
Can I get covered outside open enrollment in South Carolina?
Sometimes. A qualifying life event, such as losing other coverage, moving, marriage or a birth, opens a special enrollment period, usually 60 days. Private-market plans that aren't ACA plans also enroll year round, though many of them can decline an applicant. I can tell you in one call which applies to you.
What does health insurance cost in South Carolina?
It depends on your age, your county, your income, and whether a private-market or marketplace plan fits better. Text me your zip code and age and I will give you real numbers the same day.

Get my options →The bottom line
South Carolina uses the federal marketplace and never expanded Medicaid, which leaves a band of income where neither program reaches you. Most national advice glosses over it. If your income moves around, and self-employed income usually does, the estimate you put on the application matters more than the plan you choose.
That is worth getting right before you enroll rather than discovering it at tax time. Call or text and we will work through the number together. If you employ people, the small business guide covers the employer side.
