Before You Turn 65 in Greenville: Know the Two Paths

GREENVILLE, S.C. — If you are turning 65 soon or rethinking your coverage, you will run into the same fork in the road every Medicare shopper faces. On one side is Original Medicare, often paired with a Medigap policy and a separate drug plan. On the other is Medicare Advantage, which bundles your coverage through a private insurer. They are built differently, and the difference matters more than most brochures let on.

Greenville is in Greenville County, where both paths are available. Which one fits you depends less on marketing and more on how each is structured.

Two different building blocks

Original Medicare is the federal program itself. Part A covers hospital stays, and Part B covers doctor visits and outpatient care. You can see any provider in the country that accepts Medicare — no network. But Original Medicare does not cap what you pay out of pocket each year, and it does not include prescription drugs.

That is where the add-ons come in. A Medigap (Medicare Supplement) policy, sold by a private insurer, helps pay the deductibles and coinsurance Original Medicare leaves behind. A separate Part D plan covers your prescriptions. Three pieces, three premiums, one flexible way to get care.

Medicare Advantage works differently. A private insurer, approved by Medicare, delivers your Part A and Part B benefits — usually with Part D drug coverage folded in. Most plans use a provider network (HMO or PPO) and require referrals or prior authorization for certain services. Every Medicare Advantage plan must include an annual out-of-pocket maximum for Parts A and B, which Original Medicare on its own does not have.

How costs are shaped

With Original Medicare plus Medigap, your monthly outlay is more predictable but usually higher: you are paying a Part B premium, a Medigap premium, and a Part D premium. In exchange, cost-sharing at the point of care is minimal with most Medigap letter plans.

With Medicare Advantage, monthly premiums are often lower (sometimes only the Part B premium), but you pay copays and coinsurance as you use services, up to the plan's yearly cap.

Two figures apply to drug coverage no matter which route you pick:

• The Part D out-of-pocket cap is $2,100 in 2026 and $2,400 in 2027.
• The Part D deductible cannot exceed $615 in 2026 or $700 in 2027.

The old "donut hole" coverage gap is gone as of 2025 — Part D now has three phases instead of four. If drug costs are tough to spread across a year, the Medicare Prescription Payment Plan lets you pay them monthly instead of all at the pharmacy counter.

Higher-income enrollees should also know about IRMAA, an income-based surcharge on Part B and Part D premiums. For a single filer in 2026, it starts above $109,000 in income.

How choosing a doctor works

This is the practical difference many Greenville-area readers care about most.

Original Medicare lets you see any provider in the U.S. that accepts Medicare — helpful if you split time between states, travel often, or want access to specialists outside a network. Medigap follows you anywhere Medicare is accepted.

Medicare Advantage plans generally ask you to use in-network providers in the plan's service area. Some plans cover out-of-network care at a higher cost; others do not cover it at all except in emergencies. If you have a specific doctor or hospital system in the Upstate you want to keep, check each plan's network before enrolling.

Extra benefits and the trade-off

Medicare Advantage plans often include benefits Original Medicare does not, such as routine dental, vision, hearing, or fitness programs. Those extras are one reason many people choose Advantage. The trade-off is the network and the plan's rules for approving certain services.

Original Medicare with Medigap does not bundle those extras, but it gives you broader provider choice and, for many people, fewer coverage decisions to argue about.

The Medigap timing rule people miss

There is one wrinkle worth understanding early. When you first enroll in Part B at 65, you get a six-month Medigap Open Enrollment Period during which insurers must sell you a policy regardless of your health. Outside that window — and outside a few special situations — insurers in South Carolina can use medical underwriting to decide whether to offer you a Medigap policy and at what price.

That means switching from Medicare Advantage back to Original Medicare plus Medigap later in life is not always simple. It is worth thinking about at the start, not after a diagnosis.

When you can choose or switch

• Initial Enrollment Period: the seven months around your 65th birthday.
• Annual Enrollment Period (AEP): Oct. 15 – Dec. 7 each year. You can join, drop, or switch Medicare Advantage and Part D plans.
• Medicare Advantage Open Enrollment Period: Jan. 1 – March 31. If you are already in a Medicare Advantage plan, you can switch to another one or return to Original Medicare (and pick up a Part D plan).

Special Enrollment Periods may apply if you move, lose other coverage, or your plan changes.
