Oscar Health vs Cigna in South Carolina
In South Carolina, marketplace plans are sold through HealthCare.gov, and neither carrier is on it for 2026. Plan availability, networks, and premiums vary significantly by county and ZIP code across South Carolina — what is available in Columbia, Greenville, and Charleston is not necessarily available in smaller or rural parts of the state.
The most important thing to understand about comparing any two marketplace carriers: premium is not the same as cost. A plan with a lower monthly premium may have a higher deductible, narrower network, or worse formulary coverage for your medications — resulting in higher total annual spending than a plan that cost more per month.

How to Choose Between the Two
Neither carrier sells 2026 marketplace plans in South Carolina, so compare the insurers that do: Ambetter from Absolute Total Care, BlueCross BlueShield of South Carolina, First Choice Next, InStil Health, Molina Healthcare and UnitedHealthcare. Compare their after-subsidy premiums, network coverage for your specific doctors, and formulary coverage for your prescriptions before deciding.
If you qualify for ACA subsidies: Compare after-subsidy costs: the cheaper-looking plan before subsidies may not be cheapest after your premium tax credit is applied.
If you are paying full unsubsidized cost: At full unsubsidized cost, total annual cost (premium + expected out-of-pocket) determines value. Consider deductible, OOP max, and network breadth.
What to Check Before You Choose
Before selecting either plan, do these four checks using each carrier’s provider directory and formulary tool:
- Doctor check: Search for your primary care physician and any specialists you see regularly in each carrier’s South Carolina provider directory. Networks can be narrow, and a doctor who is in-network with one carrier may not be with the other.
- Hospital check: Confirm the hospital you would go to for a planned procedure or emergency is in-network. Hospital network participation differs from physician network participation.
- Drug formulary check: Look up every prescription you take in the formulary for each plan you are considering. Note the tier and the cost-sharing for each. Small formulary differences can result in hundreds of dollars in annual cost difference.
- After-subsidy premium: If you qualify for a premium tax credit, enter your income and household size at the federal marketplace (healthcare.gov) to see the after-subsidy premium for each plan. The after-subsidy number is what you actually pay.
This state has NOT expanded Medicaid. Buyers below the federal poverty level (~$15,650/year for one adult) may fall into the coverage gap with no affordable option unless they qualify for CHIP or other programs.
