Working past 65 in Danville? How employer size shapes your Medicare timing

Danville is in Vermilion County, and the Medicare rules for workers here are the same nationwide — but one detail changes everything: how many people your employer has on the payroll.

The rule that decides your timing

If your company (or your spouse's company, if you're covered through them) has 20 or more employees, the group health plan is the primary payer. Medicare pays second. That means many workers can safely delay Part B while they stay on the job plan.

If the employer has fewer than 20 employees, Medicare is usually the primary payer. In that case, the group plan may pay very little — or nothing — for services Medicare would have covered. Signing up for Part B at 65 is usually the right move.

Part A is almost always free — should you take it?

Most people qualify for premium-free Part A (hospital insurance) at 65 based on their own or a spouse's work history. Enrolling in Part A while still working is common and usually harmless — unless you contribute to a Health Savings Account (HSA).

Once you enroll in any part of Medicare, you can no longer make new HSA contributions. If your HSA matters to you, talk with your benefits office before signing up for Part A.

When your job ends: the 8-month window

When your employment or your employer coverage ends (whichever comes first), you get a Special Enrollment Period of up to 8 months to sign up for Part B without a late-enrollment penalty. COBRA and retiree coverage do not extend this window — the clock starts when the active employer coverage ends.

Missing this window can mean a lifelong Part B penalty of 10% for every 12-month period you could have had it but didn't.

Drug coverage: check your "creditable coverage" letter

Each fall, your employer plan should send you a notice telling you whether its drug coverage is creditable — meaning it's at least as good as a standard Medicare Part D plan. Keep that letter.

• If your job coverage is creditable, you can delay Part D without penalty.
• If it isn't, signing up for a Part D plan when you're first eligible avoids a lifelong late-enrollment penalty.

Looking ahead, Part D has a $2,400 annual out-of-pocket cap in 2027 and a maximum deductible of $700 in 2027. The coverage gap (the old "donut hole") no longer exists — the program moved to three phases in 2025. Medicare also offers the Medicare Prescription Payment Plan, which lets you spread drug costs into monthly payments.

Higher earners: know about IRMAA

If your income is above $109,000 as a single filer (or $218,000 filing jointly) in 2026, you'll pay an income-related surcharge on top of the standard Part B and Part D premiums. Social Security uses your tax return from two years earlier. If you retire and your income drops, you can ask for a reconsideration using a life-changing event form.

What to do a few months before you're ready

1. Ask your HR or benefits office, in writing, whether the plan is primary or secondary to Medicare and whether the drug coverage is creditable. 2. Decide about Part A and your HSA. 3. Mark your Special Enrollment Period dates if you plan to keep working past 65. 4. When you're ready to leave the job plan, compare your options during your Initial Enrollment Period or Special Enrollment Period — not during the general Annual Enrollment Period (Oct. 15 – Dec. 7), which is for people already on Medicare.
