Medicare and Employer Coverage While Working in Rock Hill

In Rock Hill, plenty of people keep working past 65 — at Piedmont Medical Center, the school district, small businesses along Cherry Road, or a shop of their own. If that's you, one of the trickiest Medicare questions is simple to ask and harder to answer: do I sign up now, or wait?

The right answer depends on the kind of health coverage you have at work, the size of your employer, and a few deadlines that can be expensive to miss. Here's how to think it through.

Start with your Initial Enrollment Period

Your Initial Enrollment Period is a 7-month window around your 65th birthday: the 3 months before, your birthday month, and the 3 months after. This is when most people first become eligible for Medicare, whether they enroll or not.

Even if you plan to stay on your job's insurance, it's worth looking at Part A (hospital insurance) during this window. Most people qualify for premium-free Part A because they or a spouse paid Medicare taxes long enough. Signing up rarely hurts, and it can help pick up hospital costs your work plan doesn't.

Part B (doctor visits and outpatient care) is where the real decision sits, because Part B has a monthly premium and a lifetime late-enrollment penalty if you sign up at the wrong time.

The 20-employee rule

Here's the piece most people miss. Medicare's rules for working past 65 depend on how big your employer is.

• 20 or more employees: Your group health plan is generally the primary payer, and Medicare would be secondary. You can usually delay Part B while you keep that coverage, then sign up later without a penalty.
• Fewer than 20 employees: Medicare is generally the primary payer once you turn 65. If you don't enroll in Part B, your employer plan may pay very little — or nothing — for services Medicare would have covered. That can leave you exposed.

If you work for a small employer in York County, ask your HR or benefits administrator, in writing, how the plan coordinates with Medicare at 65. Don't guess.

Special Enrollment Period when you leave work

When your job or your job-based coverage ends, you get a Special Enrollment Period to sign up for Part B. It lasts up to 8 months after the coverage or the job ends, whichever comes first. Using this window keeps you clear of the Part B late-enrollment penalty, which can otherwise add 10% to your premium for each full 12-month period you could have had Part B but didn't.

A couple of common tripwires:

• COBRA doesn't count as "current" employer coverage for delaying Part B. If you rely on COBRA past 65, the clock on your Special Enrollment Period may already be running.
• Retiree health coverage doesn't count either. Same issue — enroll in Part B when active employment ends.

Don't forget prescription drugs

If you delay Part D (drug coverage), you need "creditable" drug coverage from your employer plan in the meantime — that means coverage at least as good as standard Medicare drug coverage. Your plan is required to send you a notice each year telling you whether it is creditable. Keep those letters. If your employer coverage is not creditable and you go more than 63 days without Part D, you can face a lifetime Part D late-enrollment penalty.

A few Part D figures worth knowing when you eventually shop for drug coverage:

• The Part D out-of-pocket cap is $2,100 in 2026.
• The Part D deductible cannot be more than $615.
• The old "donut hole" coverage gap has been gone since 2025 — Part D now has three phases.
• The Medicare Prescription Payment Plan lets you spread your drug costs across the year in monthly amounts instead of paying big bills at the pharmacy counter.

Also keep an eye on income. IRMAA — the higher-income surcharge on Part B and Part D — starts above $109,000 for a single filer in 2026 (higher for joint filers). If you're still earning strong wages, that surcharge can factor into whether you delay Part B.

What's available around Rock Hill

Rock Hill is in York County, where a range of Medicare Advantage and stand-alone Part D plans is offered each year by several carriers. Plan choices, premiums, and networks are set at the county level and change every year, so it's worth comparing options during the Annual Enrollment Period, October 15 through December 7, before your coverage year begins. If you enroll in a Medicare Advantage plan and want to change it, there's also a Medicare Advantage Open Enrollment Period from January 1 through March 31.

You can see the current plans for your ZIP code using the Plan Finder at medicare.gov.

A simple way to decide

If you're still working in Rock Hill and approaching 65, walk through these questions in order:

1. Does my employer have 20 or more employees? 2. Is my drug coverage creditable? (Check the annual notice.) 3. When do I actually plan to retire or drop the job plan? 4. Would paying a Part B premium now make sense given my income and how much care I use?

Your HR or benefits office can answer #1 and #2. A local counselor can help with #3 and #4 without trying to sell you anything.
