Best Health Insurance in South Carolina (2026)

The most important number when comparing South Carolina health insurance is the annual ceiling on what you'll pay when you're sick. Ambetter has the lowest of any carrier in the state's 2026 marketplace, which is why it's the best choice for most South Carolina residents. 

In practice, the annual ceiling limits how much you could end up paying when you need surgery or have a health emergency. Blue Cross Blue Shield costs $14 less per month but its Silver deductible is $852 above Ambetter's at $4,064. The monthly savings takes more than five years to offset that deductible difference.   

First Choice Next is the stronger pick if you use care more than a few times a year. Its deductible is $1,022 lower than Ambetter's, so your insurer starts paying earlier on every visit. Blue Cross Blue Shield is the pick if you need coverage for doctors outside your insurer's approved provider list. No other South Carolina carrier in 2026 provides that option, which is why it appears on this list despite carrying the highest Silver deductible in the state.

*Our picks are the best health insurance options for 40-year-olds looking for Silver-tier HMO plans. 

Health insurance has three costs. The premium goes out every month, sick or not. The deductible is what you pay before your insurer starts covering your care. The out-of-pocket maximum sets the ceiling on what you pay in a year beyond premiums.

Ambetter's $5,545 Silver out-of-pocket maximum is the lowest in South Carolina's 2026 marketplace, $33 below the next closest carrier.

First Choice Next's $2,190 Silver deductible is the lowest in South Carolina's 2026 market, $1,022 below Ambetter and $1,874 below Blue Cross Blue Shield. For regular health care users, the lower deductible means your plan starts sharing costs sooner than with any competing carrier.

Blue Cross Blue Shield is the only 2026 marketplace carrier in South Carolina with all four plan types, HMO, PPO, EPO and POS. Its Silver plan at $576 per month is the cheapest among the six carriers we reviewed, $35 below the state average. The trade-off is the state's highest Silver deductible at $4,064.

The table lets you filter South Carolina's 2026 marketplace plans by age, plan type, metal tier and HSA eligibility. Not every carrier serves every county. Filter by your ZIP code on HealthCare.gov to confirm which plans are available where you live before comparing premiums or deductibles here.

South Carolina hasn't expanded Medicaid. Adults earning below the federal poverty level don't qualify for state Medicaid and can't access marketplace subsidies. More South Carolinians fall through this coverage hole than in most states. Enter your household income and size at HealthCare.gov to see whether you qualify for premium tax credits or Medicaid.

Plan type drives cost more than carrier in South Carolina's 2026 market. HMO plans are cheapest at every tier because they limit care to a set provider network. When a carrier controls which doctors and hospitals are covered, it takes on less financial risk and charges lower premiums. PPO and POS plans cost more because they cover some out-of-network care. Blue Cross Blue Shield is the only POS carrier in the state.

South Carolina's 2026 HMO costs range from $426 for Bronze to $653 for Gold. POS plans from Blue Cross Blue Shield are the lowest-cost Silver and Gold option in the state at $572 and $621 per month.

UnitedHealthcare has South Carolina's highest Silver premium at $766 per month. For residents who expect to meet their deductible in a given year and can absorb the higher monthly cost, UnitedHealthcare's $2,529 deductible is $683 below Ambetter's and $339 above First Choice Next's $2,190.

Which carrier costs less over a year depends on how often you use care, not which premium is lowest. Your provider network determines whether your doctors are covered at no additional cost.

South Carolina and federal agencies have free resources for comparing plans, applying for subsidies and resolving coverage disputes. These links are current for 2026.   

• HealthCare.gov: The federal marketplace where South Carolina residents compare ACA health insurance plans, check subsidy eligibility and enroll during open enrollment or a Special Enrollment Period after a qualifying life event.
• South Carolina Department of Insurance: Provides consumer guides on coverage options, helps resolve billing or claims disputes with insurers and handles complaints against carriers doing business in the state.
• South Carolina Department of Health and Human Services: Information on South Carolina Medicaid (Healthy Connections), CHIP and other public health programs, including eligibility requirements and how to apply.
• Find Local Enrollment Assistance: Search for certified enrollment navigators in your county who help you compare plans and complete your marketplace application at no cost.

Medicare covers adults 65 and older and some younger adults with qualifying disabilities. It's a federal program separate from the ACA marketplace, with different enrollment periods and plan types. If you or someone in your household is approaching Medicare age, review both types below before your 65th birthday. Enrollment windows have strict deadlines.

• Best Medicare Supplement Plans in South Carolina: Medicare Supplement plans, also called Medigap, help cover out-of-pocket costs that Original Medicare doesn't pay, such as deductibles, copays and co-insurance.  
• Best Medicare Advantage Plans in South Carolina: Medicare Advantage replaces Original Medicare and often adds prescription drug coverage along with dental, vision and hearing benefits.

My pick for most South Carolina residents is Ambetter. Its $5,545 out-of-pocket maximum is the lowest Silver ceiling in the state and cost-sharing beyond the monthly premium is capped lower than with any competing carrier. 

If you see a doctor more than twice a year, First Choice Next is the stronger pick. Its $2,190 Silver deductible is the lowest in the state. You'll pay $456 more per year in premiums than with Ambetter, but save $1,022 the first time you meet your deductible.   

South Carolina residents who need to see specialists outside a standard network, or who split their time between states, will find plan-type flexibility more valuable than a lower deductible. Blue Cross Blue Shield is the only 2026 carrier with PPO and POS options, and its HMO Bronze at $386 is the state's lowest Bronze entry point. The trade-off is the highest Silver deductible in the state at $4,064.   

If you live in Charleston-area counties, Molina Healthcare is the carrier to compare first. It leads on rates there and averages $584 per month for Silver HMO statewide, $6 below Ambetter and $8 above Blue Cross Blue Shield. Confirm county availability at HealthCare.gov before enrolling.

We ranked the best South Carolina health insurance providers by focusing heavily on monthly premiums since they create the highest ongoing cost. Maximum out-of-pocket limits and deductibles were also reviewed, which affect your total annual spending.

• Deductible (20%): The deductible is what you pay before your insurer starts sharing costs. South Carolina's 2026 Silver HMO deductibles range from $2,190 at First Choice Next to $4,064 at Blue Cross Blue Shield, a $1,874 difference. Lower average deductibles earn higher scores.
