South Carolina’s largest metro has a deep Medicare menu and a care map split between Prisma Health and Bon Secours St. Francis, with Spartanburg Regional reaching in from the east.
What to know before you compare plans in Greenville County
Greenville County offers dozens of Medicare Advantage plans, every Medigap carrier in South Carolina and the full Part D lineup. The network question is the whole question: Prisma Health Greenville Memorial and its Upstate hospitals, Bon Secours St. Francis downtown and on the east side, and Spartanburg Regional’s Pelham campus in Greer each sign their own Advantage contracts, and a plan built around one may exclude another.
Greenville retirees travel more than most and many keep a mountain place or a grandchild’s spare room in another state, which is where a Medigap policy’s any-provider access matters. We compare what is sold at your ZIP code, confirm your doctors and pharmacy, and set Advantage beside a supplement so the trade-off is plain.

Your options
Which kind of plan fits you in Greenville?
Medicare Advantage
All-in-one Part C plans, often $0 premium, that use a local network — so your providers, your county and your prescriptions matter.
Medigap pairs with Original Medicare and lets you see any provider nationwide that accepts Medicare — MUSC, Prisma, Duke or Emory across the line, or the hospital in your county seat.
Greenville County typically offers dozens of Medicare Advantage plans, every Medigap carrier in South Carolina, and the full Part D lineup, set by ZIP code and changing each plan year.
Are Prisma and Bon Secours St. Francis in the same plans?
Rarely both in every plan. Each accepts Original Medicare and therefore any Medigap policy, and each contracts with some Medicare Advantage plans and not others; the contracts change yearly. We confirm your doctors and hospital are in-network before you enroll.
How much does your help cost?
Nothing. Independent agents are paid by the carriers when you enroll, so comparing plans and reviewing your coverage each year is free to you.
