Medicare in South Carolina: 2025 Guide
South Carolina is one of the fastest-growing retirement destinations in the Southeast, drawing retirees to coastal communities like Hilton Head, Beaufort, and Myrtle Beach as well as inland cities like Greenville and Columbia. With approximately 1.2 million Medicare beneficiaries and a Medicare Advantage penetration rate of around 55%, South Carolina has a well-developed Medicare market in its urban and coastal areas, though rural counties still face limited plan competition. South Carolina has not expanded Medicaid under the Affordable Care Act, which creates a coverage gap for some lower-income residents who do not qualify for full Medicaid but remain below the threshold for marketplace subsidies.
Medicare Advantage Plans in South Carolina
South Carolina's Medicare Advantage market is most competitive in and around its major metropolitan areas. In Charleston, Myrtle Beach, Greenville, and Columbia, beneficiaries typically have access to a wide variety of plans including HMOs, PPOs, and Dual Eligible Special Needs Plans (D-SNPs). Major insurers operating in the state include UnitedHealthcare, Humana, BlueCross BlueShield of South Carolina, and Centene (through its Allwell brand), all of which maintain active presences in the state's most populated counties. Beneficiaries in these areas often have 20 or more plan options to compare during the Annual Enrollment Period.
The picture is considerably different in rural South Carolina. Counties in the Pee Dee region, the Lowcountry, and the rural Upstate may have only a handful of plans available — or in some cases, very limited MA options that may not include a broad enough provider network for beneficiaries who rely on local hospitals and specialists. Residents in these areas may find that Original Medicare combined with a Medigap (Medicare Supplement) policy provides more predictable coverage given the limitations of local MA networks. SC SHIP counselors can help rural beneficiaries evaluate whether Medicare Advantage or Original Medicare with Medigap is a better fit for their individual situation.
South Carolina's appeal as a retirement destination means the Medicare-eligible population continues to grow, which drives ongoing insurer investment in the state's markets. Coastal retirement communities such as Hilton Head Island and the Beaufort area have seen growing plan availability in recent years as insurers follow population trends. Beneficiaries who recently relocated to South Carolina from another state should be aware that they qualify for a Special Enrollment Period to switch Medicare Advantage plans after a permanent move, even outside of the Annual Enrollment Period.
Medicare Savings Programs in South Carolina
South Carolina's Medicare Savings Programs (MSPs) are administered by the South Carolina Department of Health and Human Services (SCDHHS). The MSPs help low-income Medicare beneficiaries pay for Part B premiums and, at higher levels of assistance, Part A and Part B deductibles and cost-sharing as well. The four MSP tiers — Qualified Medicare Beneficiary (QMB), Specified Low-Income Medicare Beneficiary (SLMB), Qualifying Individual (QI), and Qualified Disabled and Working Individuals (QDWI) — each have distinct income and asset thresholds. Qualifying for QMB provides the most comprehensive cost-sharing protection and also makes beneficiaries automatically eligible for the federal Extra Help program for prescription drug costs.
Because South Carolina has not expanded Medicaid, some low-income adults between ages 19 and 64 fall into a coverage gap and are not eligible for either full Medicaid or Marketplace subsidies. However, individuals who are 65 or older and eligible for Medicare can still apply for Medicare Savings Programs regardless of the state's Medicaid expansion status. To apply for an MSP in South Carolina, contact SCDHHS at 1-888-549-0820 or visit a local SCDHHS office. Income and asset limits are adjusted annually, so beneficiaries who were previously denied may want to reapply. SC SHIP counselors can provide free assistance with the MSP application process.
State Pharmaceutical Assistance in South Carolina
South Carolina does not operate a State Pharmaceutical Assistance Program (SPAP) for Medicare beneficiaries. Residents who need help paying for prescription drugs under Medicare Part D should apply for the federal Extra Help program (also known as the Low Income Subsidy, or LIS), which is administered by the Social Security Administration. Extra Help can significantly reduce Medicare Part D premiums, deductibles, and copayments for eligible beneficiaries. Automatic qualification for Extra Help applies to anyone who receives full Medicaid, SSI, or a Medicare Savings Program benefit.
South Carolina beneficiaries who do not qualify for Extra Help but still struggle with drug costs should also ask about the Medicare Part D Extra Help program's partial subsidy tier, which extends assistance to beneficiaries with somewhat higher incomes. Additionally, many pharmaceutical manufacturers offer Patient Assistance Programs (PAPs) that provide free or low-cost medications directly. SC SHIP counselors at 1-800-868-9095 can help beneficiaries identify all available programs and assist with applications at no charge.
Getting Free Medicare Help in South Carolina
The SC SHIP (South Carolina State Health Insurance Assistance Program) provides free, unbiased Medicare counseling to South Carolina residents. Operated through the South Carolina Department on Aging and the DHHS aging services network, SC SHIP counselors help beneficiaries compare Medicare Advantage and Part D plans, understand their Medigap rights, apply for financial assistance programs, and resolve billing problems and appeals. The statewide toll-free number is 1-800-868-9095, and local counseling sites are available in all 46 South Carolina counties through Area Agencies on Aging and senior centers.
SC SHIP also provides special outreach to rural communities and newly retired beneficiaries who may be navigating Medicare for the first time. Counselors are available for in-person appointments throughout the state and conduct group education events at libraries, churches, senior centers, and retirement communities. During the Annual Enrollment Period (October 15 – December 7), SC SHIP ramps up staffing and outreach to handle the increased demand for plan comparison assistance. All SC SHIP services are completely free — counselors are not insurance agents and receive no compensation based on plan enrollment.
Plan availability in South Carolina varies significantly by location. Beneficiaries in urban and coastal areas such as Charleston, Myrtle Beach, Greenville, and Columbia typically have access to 20 or more Medicare Advantage plans, with options from major insurers including UnitedHealthcare, Humana, BlueCross BlueShield of SC, and Centene. In contrast, rural South Carolina counties may have only a few plan options or limited network coverage. Use the Medicare Plan Finder at Medicare.gov to see plans available in your specific ZIP code, or call SC SHIP at 1-800-868-9095 for free personalized assistance comparing your options.
Most Medicare beneficiaries aged 65 and older are not directly affected by South Carolina's decision not to expand Medicaid, because they qualify for Medicare regardless of income. However, the Medicaid coverage gap does affect individuals under 65 who receive Medicare due to disability and who have incomes between 100% and 138% of the federal poverty level — they may not qualify for full Medicaid but face very high costs. Medicare Savings Programs remain available to Medicare beneficiaries of all ages who meet income thresholds, helping pay Part B premiums and cost-sharing. Contact SCDHHS at 1-888-549-0820 or SC SHIP at 1-800-868-9095 to learn whether you qualify for MSP assistance.
