Medicare Advantage plans in South Carolina

A Medicare Advantage plan (also called Part C) is an all-in-one alternative to Original Medicare, offered by private insurers that Medicare approves and pays. You still have Medicare, but the plan administers your Part A and Part B coverage and almost always folds in Part D drug coverage too. In South Carolina the plan is sold by county, and which carriers sell in your county — and which hospitals they have signed — changes every October.

What’s usually included

• Hospital and medical coverage (your Part A and Part B benefits).
• Prescription drug coverage in most plans — so you don’t buy a separate Part D plan.
• Extras Original Medicare doesn’t cover, which can include dental, vision, hearing, fitness benefits, and an annual out-of-pocket maximum that caps what you spend on covered care.

The trade-off: networks, county by county

Advantage plans use provider networks (HMO or PPO) and are sold by county. That is the single most important thing to check before you enroll: whether your doctors and your hospital are in the plan’s network, and whether your medications are on its drug list. South Carolina’s care is organized into a handful of large systems — Prisma Health in the Upstate and Midlands, MUSC Health from Charleston to Florence, Lancaster and Columbia, Roper St. Francis and Trident in the Lowcountry, Spartanburg Regional, McLeod and Grand Strand along the coast and the Pee Dee, Lexington Medical Center, AnMed, Self Regional, Tidelands and the Novant hospitals in Beaufort and Jasper counties — and each contracts with some plans and not others. We confirm your providers and prescriptions are covered before you sign anything.

If your plan left your county

A non-renewal notice is not just bad news; it opens doors. You get a Special Enrollment Period that runs past the normal deadlines, and because the plan left you involuntarily, federal rules give most people a guaranteed-issue right to buy a Medigap policy without medical underwriting — even if you are well past your original six-month Medigap window. The right is time-limited (generally 63 days after your coverage ends), so do not let the notice sit. South Carolina has no birthday rule or annual Medigap window to fall back on afterward.

Who Medicare Advantage tends to suit

People who want predictable, lower upfront costs and value bundled extras, who are comfortable using a plan network, and who live where the menu is deep. If you split the year between the coast and a grandchild up north, see specialists at Duke, Emory or Mayo, or want to use any provider nationwide, compare it against a Medigap policy — our moving to South Carolina guide walks through which plans travel. Military retirees with TRICARE For Life have their own calculation; see Veterans.

There are also specialized Advantage plans for specific situations: Chronic Special Needs Plans (C-SNPs), Institutional SNPs (I-SNPs), and Dual Special Needs Plans for people with both Medicare and Healthy Connections Medicaid, which took over from Healthy Connections Prime at the start of 2026.
