Medicare in plain English

Medicare is federal health coverage, mostly for people 65 and older and for some people under 65 who have been receiving disability benefits. It is not one policy. It is a set of parts you assemble, and the assembly is where almost all of the confusion lives.

The rules are identical in every state. What is not identical is what you can actually buy with them. Medicare Advantage and Part D availability varies by county and ZIP code, and in York County — Rock Hill, Fort Mill, Tega Cay, Indian Land and York — that single fact changes the shape of the decision, because so many households here keep doctors on both sides of the Charlotte line.

The parts, one at a time

Part A — hospital coverage

Inpatient hospital stays, skilled nursing after a qualifying stay, hospice and some home health care. Most people pay $0 for Part A because they or a spouse paid Medicare taxes for at least 40 quarters. If you have 30 to 39 quarters the premium is $311 a month; with fewer than 30 it is $565 a month.

A $0 premium does not mean $0 when you use it. There is a $1,736 deductible per benefit period, then $434 a day for hospital days 61 through 90, and $868 a day for lifetime reserve days 91 through 150.

Part B — medical coverage

Doctor visits, outpatient care, lab work, imaging, durable medical equipment and preventive services. The standard premium in 2026 is $202.90 a month, with an annual deductible of $283. After the deductible, Original Medicare generally pays 80% of the approved amount for most Part B services and you pay the remaining 20% — with no annual ceiling on that 20%, which is the single most important structural fact on this page.

Part C — Medicare Advantage

A private plan that delivers your Part A and Part B benefits in one package, usually with drug coverage built in, always with an annual cap on your out-of-pocket costs for covered in-network care, and always through a provider network. You stay in Medicare and keep paying the Part B premium. How Medicare Advantage works in South Carolina covers it properly.

Part D — prescription drugs

Drug coverage, either as a stand-alone plan alongside Original Medicare or built into a Medicare Advantage plan. Your out-of-pocket spending on covered drugs is capped at $2,100 in 2026 and $2,400 in 2027, and a plan's drug deductible can be no more than $615 in 2026 or $700 in 2027. See what Part D is for how the tiers and pharmacies work underneath those limits.

The two roads

Once you have Part A and Part B, there are two ways to finish the job, and they are genuinely different roads rather than two versions of the same one.

  • Original Medicare, usually with a Medicare Supplement and a stand-alone drug plan. You can see any provider in the country who accepts Medicare, with no network and no referrals. The supplement covers much of what Medicare leaves behind, which is how you put a ceiling on that uncapped 20%. You pay more in monthly premium for more predictability.
  • Medicare Advantage. One plan, usually with drugs and extras included and a hard annual cap on in-network costs, but care runs through a network and sometimes through referrals.

We will not tell you one road is better. It depends on your doctors, your medications, your budget and how much uncertainty you are willing to carry. For a household here, though, there is an extra question stacked on top: a network has to hold together across a state line. If your primary care doctor is in Rock Hill and your cardiologist is in Charlotte, the question is never whether a plan is good in general — it is whether that specific plan covers those specific providers. That is checkable, and it has to be checked before you enroll rather than after the first appointment.

When you sign up

Your first window is the 7-month Initial Enrollment Period: the three months before your birthday month, the month itself, and the three months after. If you are still working past 65 with employer coverage — very common here, often for a Charlotte employer — you may be able to delay Part B and use an 8-month Special Enrollment Period when the job or the coverage ends. Whether that applies turns on the size of the employer, not on how good the coverage feels: see Medicare alongside employer coverage.

After that, the windows repeat. The Annual Enrollment Period runs October 15 to December 7 with changes effective January 1, and Medicare Advantage Open Enrollment runs January 1 to March 31 for people already in a Medicare Advantage plan. When you can enroll in Medicare lays all of them out, including the General Enrollment Period of January 1 through March 31 for people who missed their first chance.

One window never repeats. The Medigap Open Enrollment Period is six months beginning the first month you are both 65 or older and enrolled in Part B, and once it closes insurers can generally use medical underwriting.

Coming to Medicare before 65 in South Carolina

Medicare is not only a program for people turning 65. People receiving Social Security Disability Insurance generally wait 24 months for Medicare to begin, and those months do not have to be consecutive. ALS is an exception — no five-month disability wait and no 24-month Medicare wait, with Parts A and B set up for you. End-stage renal disease is the other exception to the standard path.

Here is where South Carolina differs from its neighbors in a way that genuinely matters. No South Carolina law requires private insurers to sell Medicare Supplement coverage to people under 65; access runs through the state pool instead. That is a real constraint, and anyone who tells you otherwise has confused this state with another one. The reassurance is equally real: a full six-month Medigap Open Enrollment Period still opens at 65, so a decision made under 65 is not the last one you get to make.

South Carolina has also not expanded Medicaid, which is worth knowing as background if you are under 65 and waiting out the 24-month period. To be clear about our own role: The Jordan Insurance Agency helps with Medicare. We do not sell or advise on Medicaid, and we will point you to the state's Medicaid agency rather than guess.

Costs beyond the premium

Two additions catch people out. The first is income-related: if your modified adjusted gross income is above $109,000 for one person or $218,000 for a couple filing jointly, an amount is added to your Part B and Part D premiums. In the first bracket that is $81.20 on Part B and $14.50 on Part D — so a first-bracket Part B total is $284.10 a month, which is the whole premium rather than a surcharge on top of it.

The second is self-inflicted and avoidable: signing up late. Part B adds 10% of the standard premium for every full 12-month period you could have had it and did not, and it generally stays for as long as you have Part B. Part D adds roughly 1% of the national base beneficiary premium ($38.99 in 2026) for each full month you went without creditable prescription drug coverage, triggered by a gap of 63 days or more. The late enrollment penalty explains both.

There is help with cost for people with limited income and resources, through Medicare Savings Programs and Extra Help. We will not tell you whether you qualify — that is checked, never asserted — but we will check it with you rather than leave you to find it.
