Health Insurance in South Carolina

Compare ACA health insurance, Medicare, life, dental, vision, supplemental, short-term, travel medical, and group coverage with licensed broker Mercy Makarevich.

South Carolina residents frequently navigate plan options that differ between coastal metro areas like Charleston, the Upstate, and central Columbia. Choosing the wrong network can lead to high out-of-network costs.

Mercy Makarevich provides one-on-one comparisons for South Carolina families and retirees and helps verify local doctors, prescriptions, coverage rules, and costs with each plan.

Where you apply for coverage in South Carolina

HealthCare.govMedicaid not expanded46 counties

South Carolina uses the federally facilitated Marketplace at HealthCare.gov. Individual and family applications, premium tax credit eligibility, and Special Enrollment Period verification are all handled federally.

South Carolina's 46 counties divide into three practical markets: the coastal Lowcountry around Charleston and Myrtle Beach, the Midlands around Columbia, and the Upstate around Greenville and Spartanburg. Network composition differs noticeably between them.

South Carolina sits directly between two states with very different Medicaid policies, and that contrast matters for households near the state line or considering a move.

Medicaid and CHIP in South Carolina

South Carolina has not adopted the ACA Medicaid expansion. Healthy Connections, the state Medicaid program, covers defined categories — children, pregnant women, some very low-income parents, people with disabilities, and qualifying older adults — rather than all adults under one income ceiling.

Because the state did not expand Medicaid, there is a well-documented coverage gap: adults whose household income falls below 100% of the federal poverty level are generally too poor to qualify for Marketplace premium tax credits, yet do not meet the state's narrow Medicaid categories. Premium tax credits begin at 100% FPL, so reporting income accurately on the application matters enormously — an estimate that lands just above or just below that line changes the entire result.

This is a live distinction for anyone moving between South Carolina and North Carolina, which expanded Medicaid in December 2023. The same household income can produce a Medicaid determination on one side of the border and a coverage gap on the other. The South Carolina Department of Health and Human Services makes all state eligibility determinations.

What drives your premium in South Carolina

South Carolina premiums are set by your county's rating area, enrollee ages, household size, tobacco use, and metal tier. Coastal, Midlands, and Upstate pricing can differ for the same coverage.

Premium tax credits are calculated against the second-lowest-cost Silver plan in your county. In a state without Medicaid expansion, the accuracy of your income estimate carries extra weight — it determines not just the size of your subsidy but whether you qualify for one at all.

Cost-sharing reductions apply only to Silver plans and only below 250% of the federal poverty level. For South Carolina households in the lower subsidy-eligible range, the deductible and out-of-pocket maximum difference between a CSR Silver plan and a Bronze plan is often far larger than the premium difference that draws people to Bronze.

When you can enroll

Individual ACA coverage is bought during an annual Open Enrollment Period, which for states on HealthCare.gov has opened on November 1 in recent plan years. Exact opening and closing dates are set per plan year, so confirm the current window on the official Marketplace site rather than relying on last year's dates.

Outside that window you need a Special Enrollment Period, which is opened by a qualifying life event. Most Special Enrollment Periods last 60 days from the event, and the Marketplace typically asks for documentation proving it.

Events that commonly open a Special Enrollment Period

  • Losing other qualifying coverage — job loss, aging off a parent's plan at 26, or exhausting COBRA
  • Moving permanently to a new coverage area
  • Getting married, or having a baby, adopting, or placing a child in foster care
  • Divorce or legal separation that causes a loss of coverage
  • Losing Medicaid or CHIP eligibility
  • Gaining lawful presence, becoming a citizen, or being released from incarceration

How Medicare timing works

Medicare runs on its own calendar, separate from the ACA Marketplace. Your Initial Enrollment Period is seven months long — the three months before the month you turn 65, your birthday month, and the three months after. Missing it can trigger Part B and Part D late enrollment penalties that last for as long as you hold the coverage.

After that, Medicare Open Enrollment runs October 15 through December 7 each year, when you can change between Original Medicare and Medicare Advantage or switch Part D plans. A separate Medicare Advantage Open Enrollment Period runs January 1 through March 31 for people already enrolled in an Advantage plan.

One window is easy to miss and hard to recover: your Medigap open enrollment is the six-month period beginning when you are 65 or older and enrolled in Part B. During those six months a Medicare Supplement insurer generally cannot use medical underwriting to deny you or raise your price. Outside it, in most states, they can.

Provider networks in South Carolina

Prisma Health is the largest system in South Carolina and anchors both the Upstate and the Midlands. MUSC Health anchors Charleston and operates regional hospitals across the state, and Roper St. Francis is a significant Charleston-area alternative.

Myrtle Beach and the Grand Strand, Florence, and the rural Pee Dee each have narrower options, and plans sold statewide do not necessarily contract with the same hospitals in every region.

Because South Carolina's individual market relies on relatively tight networks, confirm both your primary care physician and any ongoing specialist in the specific plan's directory. Seasonal and retiree households along the coast should also confirm how the plan handles care received while traveling.

Systems worth verifying

  • Prisma Health
  • MUSC Health
  • Roper St. Francis Healthcare
  • Bon Secours St. Francis
  • McLeod Health
  • Self Regional Healthcare
  • Tidelands Health
  • AnMed Health

System participation is not guaranteed and changes by plan and year. Confirm each provider in the specific plan's directory and directly with the provider before receiving care.

Before you enroll, verify these five things

  • Every doctor and hospital you intend to use, checked in that specific plan's directory — not the carrier's general directory
  • Every prescription, by exact name and dosage, checked against the plan's formulary and tier structure
  • Your realistic estimated household income for the coverage year, since this drives subsidy eligibility
  • The full cost picture: annual premium, deductible, copays, coinsurance, and out-of-pocket maximum together
  • Whether anyone in the household has an offer of employer coverage, which can affect Marketplace subsidy eligibility

South Carolina Health Insurance FAQ

Is Insure With Mercy licensed in South Carolina?

Yes. Mercy is licensed in South Carolina, providing enrollment support and rate comparisons for local residents.

Can I receive plan reviews remotely in South Carolina?

Yes. All South Carolina quote comparisons, network checks, and applications are completed online or by phone for your convenience.

Did South Carolina expand Medicaid?

No. South Carolina has not adopted ACA Medicaid expansion. Healthy Connections covers specific eligibility categories rather than all adults below a single income threshold, which leaves a coverage gap below the premium tax credit floor.

How is South Carolina different from North Carolina for coverage?

North Carolina expanded Medicaid in December 2023 and South Carolina has not. The same household income can result in Medicaid eligibility in North Carolina and a coverage gap in South Carolina.

Which hospital systems should I verify in South Carolina?

Most enrollees need to check Prisma Health, MUSC Health, or Roper St. Francis depending on region, plus any regional hospital in the Pee Dee, Grand Strand, or Lowcountry. Participation is plan-specific.

Do coastal and Upstate premiums differ in South Carolina?

They can. Premiums are set by rating area, so the Lowcountry, Midlands, and Upstate may price the same metal tier differently, and network composition differs as well.
