Affordable Health Insurance in South Carolina: What Most People Don't Know

By Martin Elefant · Licensed insurance agent · Updated October 2026 · 5 min read

Five facts most South Carolinians learn the expensive way.

1. "Affordable" on the marketplace means subsidized

HealthCare.gov prices are designed to be offset by the premium tax credit. Without it, you're paying the full cost of a guaranteed-issue pool.

2. There's a second market

Private shared-network plans on Cigna, Aetna and PHCS PPO price on health instead of income. For healthy people above the subsidy line they're often half the price, with a PPO.

3. Your doctor probably takes the PPO, not the HMO

National PPO networks are what most employer plans use. Many doctors in Charleston and Columbia are in the Cigna, Aetna and PHCS PPO network and not in the narrow marketplace HMOs.

4. You can enroll in a private plan any month

No waiting for November. Apply by the 20th, coverage on the 1st.

5. The deduction applies either way

South Carolina has a state income tax, so the self-employed health premium deduction reduces both federal and state taxable income.

And one South Carolina-specific thing

South Carolina didn't expand Medicaid, and most marketplace plans here are narrow-network HMOs — which is why a national PPO is the thing self-employed buyers ask about first.
