South Carolina's healthcare market has grown significantly with the expansion of the Charleston and Greenville metropolitan areas. MUSC Health (Medical University of South Carolina) is the academic anchor, while Prisma Health (a merger of Palmetto Health and Greenville Health System) is the largest provider organization in the state. These health systems shape the payer landscape, with affiliated plans and exclusive network arrangements influencing which payers matter most by region.
BlueCross BlueShield of South Carolina is the dominant commercial payer in the state, with some of the highest commercial market share of any regional Blue plan in the country. Aetna, Cigna, and United Healthcare also operate in the state, but BCBS SC's dominance makes it the unambiguous first credentialing priority for new practices.
South Carolina Healthy Connections Medicaid operates managed care through three organizations: Healthy Blue (BCBS SC), Molina Healthcare of SC, and Select Health of South Carolina (MUSC-affiliated). The state also has a fee-for-service Medicaid component for specific populations. Providers must credential with each managed care plan serving their region.
Arctic Health helps South Carolina providers credential with BCBS SC and all Healthy Connections managed care plans, ensuring complete submissions across what is one of the most BCBS-concentrated markets in the country.
