Still Working at 65 in Grand Island? Your Medicare Timing Guide

If you live in Grand Island and you're approaching 65 while still working, you may be wondering whether you need to sign up for Medicare right away — or whether your job's health plan is enough for now. The honest answer: it depends on the size of your employer, the kind of coverage you have, and a few key deadlines you don't want to miss.

Grand Island, Neb. — Turning 65 while still on the job? Here's how to think it through.

This guide walks through how Medicare fits together with employer coverage, so you can make a calm, informed decision.

Start with your Initial Enrollment Period

Your first chance to sign up for Medicare is called the Initial Enrollment Period. It's a seven-month window: the three months before you turn 65, the month of your birthday, and the three months after.

Most people should at least enroll in Part A (hospital insurance) during this window, because for many workers it has no premium. Whether you enroll in Part B (medical insurance) right away depends on your job coverage.

Does the size of your employer matter? Yes.

This is the single most important rule to understand:

• If your employer has 20 or more employees, your group health plan is usually the primary payer, and Medicare is secondary. Many people in this situation delay Part B to avoid paying a premium for coverage they don't fully need yet.
• If your employer has fewer than 20 employees, Medicare usually becomes the primary payer at 65. That means if you don't enroll in Part B, you could be left with big gaps in coverage — because your job plan may only pay what Medicare would have paid.

If you're not sure how your plan works, ask your HR or benefits office directly. It's a normal question and they hear it often.

The Special Enrollment Period protects you when you retire

If you delay Part B because you have qualifying employer coverage, you get a Special Enrollment Period to sign up later — without a late penalty. You have up to 8 months after your job or your employer coverage ends (whichever comes first) to enroll in Part B.

A couple of important cautions:

• COBRA and retiree coverage do not count as active employer coverage for this purpose. Once your active job ends, that 8-month clock starts.
• Missing the window can mean a lifetime Part B late-enrollment penalty — usually 10% added to your premium for each 12 months you could have had Part B but didn't.

If retirement is on your horizon, mark your calendar the day your employer coverage ends.

Don't forget prescription drugs (Part D)

Even if you keep your employer plan, you need to know whether its drug coverage is considered "creditable" — meaning it's at least as good as a standard Medicare Part D plan. Your employer is required to tell you this in writing each year. Keep that notice.

If your job's drug coverage is creditable, you can delay Part D without penalty. If it isn't, and you go more than 63 days without creditable coverage, you may face a Part D late-enrollment penalty later.

A few Part D facts worth knowing as you compare 2027 coverage:

• The Part D out-of-pocket cap is $2,100 in 2026 and $2,400 in 2027.
• The Part D maximum deductible is $615 in 2026 and $700 in 2027.
• The old "donut hole" coverage gap is gone as of 2025 — Part D now has three phases instead of four.
• The Medicare Prescription Payment Plan lets you spread your drug costs across the calendar year in monthly installments, at no extra charge. It's optional.

Higher earners: know about IRMAA

If your income is above certain thresholds, you'll pay an Income-Related Monthly Adjustment Amount (IRMAA) on top of your Part B and Part D premiums. For 2026, IRMAA starts above $109,000 for single filers (higher for married couples filing jointly). Social Security uses your tax return from two years earlier to decide.

If you've had a life change — retirement, a spouse's death, divorce — you can ask Social Security to reconsider using more recent income.
