The capital has a deep plan menu, three systems that contract on their own terms — Prisma, Lexington Medical Center and MUSC Health — Fort Jackson’s retirees, and the Dorn VA.
What to know before you compare plans in Richland County
Richland and Lexington counties offer a wide Advantage menu, every Medigap carrier in South Carolina and the full Part D lineup. The network question is the whole question: Prisma Health Richland and Prisma Health Baptist, Lexington Medical Center in West Columbia and MUSC Health’s Columbia hospitals each sign their own Advantage contracts, and a plan built around one may exclude another.
Columbia is also an Army town and a state-government town. Fort Jackson retirees reach 65 with TRICARE For Life, state and school-district retirees have PEBA rules, and veterans from across the Midlands use the Dorn VA. We compare what is sold at your ZIP code with all of that in front of us.

Which kind of plan fits you in Columbia?
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.
Richland and Lexington counties typically offer a wide Medicare Advantage menu, every Medigap carrier in South Carolina, and the full Part D lineup, set by ZIP code and changing each plan year.
Is Lexington Medical Center in my Advantage plan’s network?

Nothing. Independent agents are paid by the carriers when you enroll, so comparing plans and reviewing your coverage each year is free to you.
