The Army’s largest training post retires a lot of soldiers into the Midlands. TRICARE For Life, Moncrief Army Health Clinic, the Dorn VA across town — and a Medicare decision that looks different from a civilian one.
Why the Medicare choice is different for a Fort Jackson family
Richland and Lexington counties hold one of the state’s largest Army-retiree communities, and most of them reach 65 with TRICARE For Life waiting. TFL requires Medicare Parts A and B and then pays secondary to Medicare, so a Medigap policy is usually unnecessary; its pharmacy is creditable, so a Part D plan usually is too. What is left to decide is whether an MA-only Advantage plan adds dental, vision or hearing worth having, and whether its network reaches the Prisma, Lexington Medical Center or MUSC Health doctors you use.
Veterans without TRICARE use the Wm. Jennings Bryan Dorn VA Medical Center, and here the Part B timing question is the one that matters: VA care is not creditable for Part B, so delaying Part B because you have the VA triggers a lifelong penalty. Moncrief Army Health Clinic continues to see retirees on a space-available basis; it is not a substitute for Medicare.

Turning 65? Your Initial Enrollment Period is the 7 months around your birthday. Already on Medicare? The Annual Election Period is Oct 15–Dec 7, and Medicare Advantage Open Enrollment runs Jan 1–Mar 31. Moving to South Carolina, losing a plan, or a FEMA hurricane declaration each open a Special Enrollment Period.
Your options
Which kind of plan fits a military retiree here?
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.
I retired from the Army with TRICARE For Life. Do I need a Medigap policy or Part D?
Usually neither. TFL pays secondary to Medicare and its pharmacy is creditable drug coverage. An MA-only Advantage plan can add dental or vision without duplicating your drug benefit; we check whether one is worth it for you.
I use the Dorn VA. Do I still need Part B?
In most cases, yes. VA medical care is not creditable coverage for Part B, so delaying it can trigger a permanent penalty and leaves you without coverage at a non-VA hospital. Enroll on time.
Can I keep using Moncrief after 65?
Retirees can be seen at Moncrief Army Health Clinic on a space-available basis under TRICARE rules; Medicare does not pay there. Most Fort Jackson retirees pair TFL with civilian care at Prisma, Lexington Medical Center or MUSC Health.
