Clarksville Workers at 65: Medicare and Job Insurance

CLARKSVILLE, Tenn. — If you're closing in on 65 and still clocking in — whether at Fort Campbell, a Hankook plant, Austin Peay, or a small business off Wilma Rudolph Boulevard — one of the most common questions we hear is simple: Do I have to sign up for Medicare if I already have insurance through my job?

Clarksville workers, here's the Medicare question that trips people up

The honest answer is: it depends. And getting it wrong can mean lifelong penalties or a gap in coverage. Here's how to think it through.

Start with the size of your employer

Medicare's rules hinge on how many people work at your employer (or your spouse's employer, if you're on their plan).

• 20 or more employees: Your job-based insurance is generally the primary payer, and Medicare would be secondary. Many people in this situation delay Part B without penalty as long as the employer coverage is considered "creditable."
• Fewer than 20 employees: Medicare usually becomes the primary payer at 65, and your employer plan pays second. In that case, you typically need to enroll in Parts A and B on time, or you could be stuck with big out-of-pocket bills.

If you're not sure which category your employer falls into, ask your HR or benefits office in writing. That answer drives everything else.

Part A is usually a yes. Part B is the real decision.

Most people sign up for Part A (hospital insurance) at 65 because they've paid enough in Medicare taxes to get it premium-free. It rarely hurts to take it — though there's a wrinkle if you contribute to a Health Savings Account (HSA). Once you enroll in any part of Medicare, you can no longer contribute to an HSA. If your workplace plan is a high-deductible HSA plan, talk with HR before enrolling.

Part B (doctor and outpatient care) has a monthly premium, so this is where the "delay or not" question really lives. If your employer coverage is creditable and the company has 20+ employees, delaying Part B is often reasonable. If not, delaying can cost you.

The penalty piece — and the 8-month window

Miss your enrollment window without creditable coverage and Medicare can add a late enrollment penalty to your Part B premium — 10% for every 12 months you could have had it but didn't. That penalty typically lasts as long as you have Part B.

When you eventually leave the job or lose the employer plan, you get a Special Enrollment Period — 8 months to sign up for Part B without penalty. COBRA and retiree coverage do not count as active employer coverage for this purpose, which surprises a lot of people. The clock starts when the job or the group plan ends, whichever comes first.

Don't forget Part D — even if you're still working

Prescription drug coverage has its own rules. If your employer plan includes drug coverage that Medicare considers creditable, you can delay Part D without penalty. Your plan should send you a notice each year confirming this — keep it.

For 2027, Medicare's drug benefit includes some meaningful updates worth knowing about, whenever you do enroll:

• A $2,400 annual out-of-pocket cap on covered Part D drugs (up from $2,100 in 2026).
• A Part D deductible maximum of $700 in 2027 (up from $615 in 2026).
• The old "donut hole" is gone, replaced by a simpler three-phase structure.
• The Medicare Prescription Payment Plan lets you spread drug costs across the year in monthly installments instead of paying big amounts at the pharmacy counter.

Higher earners should also know about IRMAA — an income-related surcharge that starts above $109,000 for a single filer in 2026 and can raise your Part B and Part D premiums.
