South Carolina Health Insurance in 2027: Rules and Options

South Carolina buyers enroll through HealthCare.gov. The state's continuation law covers insured group plans and lasts the rest of the month coverage ends plus six months, after six months of coverage, at the full group premium. South Carolina's insurance department adopted the federal short-term limits in 2024, three months initial and four months total, replacing its older 11- and 33-month limits. Final 2027 individual rates average about 22 percent higher, among the largest increases on this list, while small-group plans rise a comparatively modest 8.9 percent.

Private health insurance in South Carolina

Most people I help in South Carolina end up on a private plan, not a Marketplace plan. Private, medically underwritten health insurance is priced on your age, zip code and health instead of your income, so a strong year never raises your premium and there is no tax credit to pay back in April.

Why people leave the Marketplace

Premiums keep climbing. South Carolina Marketplace premiums are rising 22.1% on average for 2027.
The subsidy cliff. Above 400 percent of the poverty level ($63,840 for one person, $132,000 for a family of four) you pay full price.
Surprise tax bills. Underestimate your income and you repay the tax credit in April.
Narrow networks. Many plans are local HMOs or EPOs that need referrals and cover little outside the area.
High out-of-pocket costs. 2027 out-of-pocket maximums reach $12,000 per person and $24,000 per family.
One window a year. Outside open enrollment you need a qualifying life event to enroll or switch.

What a private plan does differently

Start any month. If approved, coverage can begin the first of next month, with no wait for open enrollment.
Networks that travel. Many private plans use national PPO networks, which can give you in-network doctors outside South Carolina too. Networks vary by plan.
Can cost less than full-price Marketplace plans for some healthy applicants above the subsidy line.
Accident coverage the Marketplace does not offer. A private plan can be paired with accident coverage, a separate policy. What it includes varies by plan.
Approval is based on health. You answer health questions, and acceptance is not guaranteed.

With a significant health condition, or income low enough for a large tax credit, a Marketplace plan can be the better fit, and I will tell you if it is. Either way you see both side by side.

Private plans are not ACA Marketplace plans. Benefits, exclusions and pre-existing condition rules differ by plan and by state, so review the plan details before you enroll.

Short-term health plans

South Carolina's insurance department adopted the federal short-term limits in 2024, three months initial and four months total, and has not issued newer guidance. Short-term plans are medically underwritten, exclude pre-existing conditions and cap benefits, so they fit only a defined gap.
