South Carolina Health Insurance Rates by Age
Under the ACA, insurers in South Carolina can charge older adults up to 3x what they charge younger enrollees (the 3:1 age band ratio). These are average Silver plan premiums before subsidies.

|---|---|---|---|
21–25 Individual Silver plan |
$288 | $3,456 | -33% |

Subsidies Can Slash Your Premium
Most South Carolina marketplace enrollees pay far less than the listed rates. A 40-year-old earning $35,000/year could pay as little as $138/month after premium tax credits. Because South Carolina has not expanded Medicaid, adults earning below 100% FPL may fall into a coverage gap—but those between 100–400% FPL can access substantial marketplace subsidies.
South Carolina Health Insurance Rates by Plan Tier
South Carolina marketplace plans are organized into metal tiers. Lower tiers have cheaper premiums but higher out-of-pocket costs, while higher tiers cost more monthly but cover a greater share of your medical expenses.
| Plan Tier | Monthly Premium | Annual Premium | Avg. Deductible | vs. Silver Rate |
|---|---|---|---|---|
| Bronze | $315 | $3,780 | $7,400 | -27% |
| Silver | $432 | $5,184 | $5,000 | — |
| Gold | $505 | $6,060 | $1,400 | +17% |
| Platinum | $582 | $6,984 | $0 | +35% |
Which Tier Is Right for You?
Bronze works best for healthy South Carolinians who rarely visit the doctor and want the lowest premium. Silver is the most popular tier and unlocks cost-sharing reductions for low-income enrollees. Gold and Platinum suit those with chronic conditions or frequent medical needs—especially in metro areas like Charleston and Columbia where specialist care is readily accessible.
What Affects Your South Carolina Health Insurance Rate
Under the ACA, South Carolina insurers can only consider a few factors when setting your premium: age, tobacco use, location, and plan category. South Carolina allows tobacco surcharges of up to 50%, which can significantly increase premiums for smokers.

Key South Carolina Health Insurance Dates
South Carolina Health Insurance Regulations
South Carolina has not expanded Medicaid under the ACA, leaving a coverage gap for some low-income adults. The state uses the federal marketplace through HealthCare.gov and has no individual mandate.
Key South Carolina Health Insurance Protections
Period
Expansion
Type
| Regulation | Requirement | Why It Matters |
|---|---|---|
| Marketplace | HealthCare.gov | South Carolina uses the federal HealthCare.gov marketplace for individual and family health insurance enrollment, with plans from several carriers serving the Palmetto State. |
| Medicaid Expansion | No | South Carolina has not expanded Medicaid. SC Healthy Connections Medicaid only covers very low-income parents, pregnant women, children, and disabled adults. Childless adults generally do not qualify. |
| Tobacco Surcharge | Up to 50% | South Carolina allows insurers to charge tobacco users up to 50% more. A $432/month Silver plan could cost a smoker up to $648/month—an extra $2,592/year. |
| Individual Mandate | None | South Carolina has no state-level individual mandate. There is no penalty for going uninsured, but coverage is strongly recommended to protect against catastrophic medical debt. |
| Short-Term Plans | 364 Days | South Carolina allows short-term health plans up to 364 days with renewals up to 36 months. These plans are not ACA-compliant and may exclude pre-existing conditions. |
South Carolina Has a Medicaid Coverage Gap
Because South Carolina has not expanded Medicaid, adults earning below 100% of the federal poverty level (~$15,060/year for an individual) who do not qualify for SC Healthy Connections Medicaid may fall into a “coverage gap”—earning too much for Medicaid but too little for marketplace subsidies. An estimated 190,000 South Carolinians are in this gap. If you’re affected, contact a local Federally Qualified Health Center for sliding-scale care options.
Health Insurance Plan Types in South Carolina
South Carolina’s marketplace offers several plan types to fit different healthcare needs and budgets. Understanding the differences helps you choose the right balance of cost, flexibility, and provider access.
HMO (Health Maintenance Organization)
Lowest CostHow it works: You choose a primary care physician (PCP) who coordinates your care. Referrals required for specialists. Care must stay in-network except for emergencies.
Average cost in South Carolina: $358–$418/month for a Silver HMO plan (age 40).
Best for: Charleston, Columbia, and Greenville residents near major hospital systems. Ideal for families who want predictable costs and coordinated care management.
Key feature: Ambetter and BlueCross BlueShield of SC operate strong HMO networks across the state, with integrated care coordination and competitive pricing.
PPO (Preferred Provider Organization)
Most FlexibleHow it works: See any doctor without a referral. In-network care costs less, but out-of-network care is partially covered too.
Average cost in South Carolina: $468–$542/month for a Silver PPO plan (age 40).
Best for: South Carolinians who travel between cities, want to keep specific specialists at MUSC or Prisma Health, or live in rural areas with limited provider networks.
Key feature: BlueCross BlueShield of SC offers the largest PPO network in the state, covering providers at MUSC, Prisma Health, and Tidelands Health statewide.
EPO (Exclusive Provider Organization)
Good BalanceHow it works: Similar to a PPO but without out-of-network coverage (except emergencies). No referrals needed for specialists.
Average cost in South Carolina: $395–$452/month for a Silver EPO plan (age 40).
Best for: South Carolina residents who want specialist access without referrals but are comfortable staying in-network. Popular in the Charleston and Greenville metro areas.
Key feature: Combines the flexibility of a PPO (no referrals) with the lower cost of an HMO. Oscar Health offers competitive EPO plans in South Carolina’s major metro areas.
HDHP with HSA
Tax AdvantagedHow it works: High-deductible plan paired with a Health Savings Account. You pay lower premiums but more out-of-pocket until the deductible is met.
Average cost in South Carolina: $272–$342/month for a Bronze HDHP plan (age 40).
Best for: Healthy South Carolinians who want the lowest premiums and tax-advantaged savings. Popular with self-employed professionals and young adults.
Key feature: HSA contributions are tax-deductible at both the federal and South Carolina state level. South Carolina conforms to federal HSA rules, maximizing the tax advantage for Palmetto State residents.
POS (Point of Service)
OptionalHow it works: Combines HMO and PPO features. You pick a PCP and need referrals like an HMO, but can see out-of-network providers at higher cost like a PPO.
Average cost in South Carolina: $415–$482/month for a Silver POS plan (age 40).
Best for: South Carolinians who want the structure of an HMO with the safety net of occasional out-of-network access for specialists at MUSC or Prisma Health.
Key feature: Less common on South Carolina’s marketplace but available through some employers. Offers a middle ground for those unsure between HMO and PPO.
How to Save on Health Insurance in South Carolina
Without Medicaid expansion, South Carolina residents need to be especially strategic about finding affordable coverage. Here are proven strategies to keep your premiums manageable.
Check Subsidy Eligibility
South Carolina residents earning between 100% and 400% FPL can access federal premium tax credits through HealthCare.gov. A 40-year-old earning $35,000 could reduce a $432/month Silver plan to about $138/month. Enhanced subsidies under the Inflation Reduction Act have expanded eligibility for many South Carolinians.
Enroll During Open Enrollment
South Carolina’s open enrollment on HealthCare.gov runs November 1 through January 15. Enrolling by December 15 ensures coverage starts January 1. Missing open enrollment means waiting for a qualifying life event such as job loss, marriage, or the birth of a child to access marketplace plans.
Consider a Bronze or HDHP Plan
If you’re healthy and rarely visit the doctor, a Bronze plan at $315/month saves $117/month versus Silver. That’s $1,404/year in premium savings. South Carolina recognizes federal HSA tax benefits, making HDHP/HSA combinations a strong option for tax-conscious residents.
Verify Your Doctors In-Network
Before picking a plan, check the insurer’s provider directory to confirm your doctors and preferred hospitals are in-network. Ambetter has the cheapest plans but a narrower network. If you need MUSC, Prisma Health, or Bon Secours, verify which plans include your preferred providers.
Explore Community Health Centers
If you fall into the coverage gap (earning below 100% FPL and not eligible for SC Medicaid), South Carolina’s Federally Qualified Health Centers offer sliding-scale fees based on income. These centers provide primary care, dental, and mental health services regardless of insurance status or ability to pay.
Check SC Medicaid Eligibility
While South Carolina hasn’t expanded Medicaid, SC Healthy Connections still covers pregnant women, children, parents with very low income, and disabled adults. Check whether your children qualify for Medicaid or the state’s CHIP program even if you don’t qualify yourself.

What South Carolina Residents Are Saying
"As a restaurant owner in downtown Charleston, I couldn’t afford group insurance for myself. Credit Haven helped me find an Ambetter Silver plan for $148/month after subsidies. That’s a fraction of what I expected. Having real health coverage lets me focus on growing my business without worrying about one medical emergency wiping me out."
"My family of four in Columbia was paying $1,400/month through COBRA after my wife’s company downsized. Credit Haven showed us we qualified for substantial subsidies and found us a BlueCross family plan for $450/month. That’s $11,400 a year in savings. I just wish South Carolina would expand Medicaid to help more families."
"I’m a 30-year-old freelance developer in Greenville and assumed health insurance was out of reach. Credit Haven showed me a Bronze HDHP for $280/month with an HSA. The tax deduction on contributions saves me money at both the federal and state level. I should have explored marketplace options years ago."
