Medicare Part D

Still Working at 65 in Duluth? Medicare Timing Tips

DULUTH, Minn. — Turning 65 while you're still clocking in at a Duluth job? You're in good company. Plenty of workers on the North Shore are staying on the job past traditional retirement age, and that raises a fair question: do you need to sign up for Medicare right now, or can it wait?

The honest answer is, "it depends" — mostly on the size of your employer and the kind of coverage you already have. Here's how to think it through.

Start with the size of your employer

Medicare's rules treat employer coverage differently depending on how big the company is.

• 20 or more employees: Your job's health plan usually pays first, and Medicare pays second if you enroll. Many workers in this situation delay Part B without a penalty, as long as they keep that job-based coverage.
• Fewer than 20 employees: Medicare typically becomes the primary payer at 65. In small-employer situations, delaying Part B can leave gaps your job plan won't fill. Talk to your HR or benefits administrator before you decide.

If you're not sure which category your Duluth employer falls into — a small law office downtown looks very different from a large health system or the port — ask HR in writing. That answer changes everything.

Part A is usually a simple call

Most people qualify for premium-free Part A (hospital insurance) because they or a spouse paid Medicare taxes long enough. If that's you, enrolling in Part A at 65 is often harmless and can work alongside a job plan.

One big exception: if you contribute to a Health Savings Account (HSA), you cannot keep making HSA contributions once any part of Medicare (including Part A) kicks in. If your HSA matters to you, plan the timing carefully.

Part B is where timing gets real

Part B (doctor visits, outpatient care) has a monthly premium, and it's the piece most workers weigh delaying.

• If your employer coverage counts as creditable and the company has 20+ employees, you generally get a Special Enrollment Period to sign up for Part B later — up to 8 months after the job or coverage ends — without a late penalty.
• If you miss that window without qualifying coverage, you could face a lifetime Part B late penalty. That's the mistake we most want Duluth readers to avoid.

Ask your benefits office for written confirmation that your coverage is considered creditable for Medicare purposes.

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

Prescription drug coverage has its own rules. Your job's drug plan needs to be creditable (at least as good as standard Medicare Part D). Employers are supposed to send you a notice each fall telling you this — keep it.

Some Part D facts worth knowing for 2026 and 2027:

• The out-of-pocket cap for covered drugs is $2,100.
• The maximum deductible a Part D plan can charge is $615.
• The old "donut hole" coverage gap is gone as of 2025 — there are now three simpler phases.
• The Medicare Prescription Payment Plan lets you spread your drug costs into monthly installments instead of paying big bills at the pharmacy counter.

If your workplace drug coverage isn't creditable, signing up for Part D on time protects you from a lifetime late penalty later.

What Duluth workers should know about local options

Duluth sits in St. Louis County, where Medicare Advantage and Part D plan availability is set at the county level. That means when you do eventually shop — whether that's this fall or years from now — the menu of plans you see is based on the county you live in, not the city itself. If you split time between Duluth and a cabin up the Iron Range or over in Wisconsin, your permanent address decides which county's plans you can pick from.

Watch the income line if you're a higher earner

If you're still working and earning well, know about IRMAA — an income-related surcharge added to Part B and Part D premiums. For 2026, it starts kicking in above $109,000 in income for a single filer (higher for joint filers). Medicare looks back at your tax return from two years ago to decide. If your income has since dropped — say you retired — you can ask Social Security to reconsider.

Key enrollment dates to keep on the fridge

• Initial Enrollment Period: the 7 months around your 65th birthday.
• Special Enrollment Period: up to 8 months after employer coverage ends, in most cases.
• Annual Enrollment Period: October 15 – December 7 each year.
• Medicare Advantage Open Enrollment: January 1 – March 31.
