Turning 65 in Maryland Heights? When to Delay Medicare

Turning 65 in Maryland Heights? When to Delay Medicare — plain-language Medicare information for Maryland Heights, Missouri.

MARYLAND HEIGHTS, Mo. — Turning 65 while you're still punching a clock raises a fair question: do you actually need Medicare yet? For many workers in Maryland Heights, the honest answer is "it depends on the size of your employer" — and getting that call right can save you from late penalties and coverage gaps down the road.

Here's a plain-English guide to how Medicare fits with a job-based health plan, what the rules say, and where to get answers tailored to your situation.

The size of your employer matters most

The single biggest factor is how many people work for your (or your spouse's) employer.

• 20 or more employees: The group health plan is the "primary payer." Medicare is secondary. You can usually keep the job plan and delay Part B without a late penalty.
• Fewer than 20 employees: Medicare generally becomes the primary payer at 65. If you don't enroll in Part B, the group plan may pay very little — leaving you on the hook for big bills.

If you work for a smaller company, talk to the HR or benefits office before your 65th birthday to confirm how the plan coordinates with Medicare.

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

Part A (hospital insurance) is premium-free for most people who worked and paid Medicare taxes for at least 10 years. Many workers sign up for Part A at 65 even while keeping employer coverage, because it costs nothing in monthly premium.

There is one important exception: if you contribute to a Health Savings Account (HSA), you can't keep adding to it once you enroll in any part of Medicare, including Part A. If your HSA matters to you, weigh that trade-off carefully.

Part B (outpatient and doctor coverage) has a monthly premium, so many people with strong employer coverage delay it. As long as your job-based plan qualifies as "creditable" and your employer has 20+ workers, you generally won't owe a late enrollment penalty for signing up later.

Don't miss your Special Enrollment Period

When you retire or your employer coverage ends, the clock starts.

• Part B: You have an 8-month Special Enrollment Period that begins the month after employment or the group plan ends — whichever comes first. COBRA and retiree coverage do not extend this window.
• Part D (drug coverage): You generally have about 2 months after employer drug coverage ends to sign up without a late penalty, as long as your prior coverage was "creditable."

Ask your benefits office each year for a "creditable coverage" notice for prescription drugs. Keep it. That paperwork is how you prove you shouldn't owe a Part D penalty.

What about Part D and 2027 drug costs?

If your job plan includes drug coverage that Medicare considers creditable, you can delay Part D without penalty. If it doesn't — or once you leave the plan — Part D becomes important.

A few facts worth knowing as you compare 2026 and 2027:

• The Part D out-of-pocket cap is $2,100 for the year. Once you hit it, you pay $0 for covered drugs the rest of the year.
• The maximum Part D deductible is $615.
• The old "donut hole" coverage gap is gone; Part D now has three simpler phases.
• The Medicare Prescription Payment Plan lets you spread your drug costs into monthly installments instead of paying all at once at the pharmacy.

Maryland Heights sits in St. Louis County, where a number of stand-alone Part D plans and Medicare Advantage plans with drug coverage are available if you decide to leave employer coverage.

Watch out for IRMAA if you're a higher earner

If you're still working, your income may be high enough to trigger IRMAA — an income-related surcharge added to your Part B and Part D premiums. For 2026, IRMAA starts above $109,000 for single filers (and higher for joint filers). Social Security bases this on your tax return from two years ago, so a big earning year now can affect your Medicare premiums later.

If your income drops after retirement, you can ask Social Security to reconsider using Form SSA-44.

How to think through the decision

A quick checklist before your 65th birthday:

1. Ask HR: How many employees does the company have, and how does the plan work with Medicare? 2. Ask HR: Is the drug coverage "creditable" for Part D? 3. Compare what you pay now (premiums, deductibles, network) with what Medicare would cost. 4. Factor in your spouse — will they lose coverage if you drop the group plan? 5. Think about HSA contributions before enrolling in any part of Medicare.

There's no one right answer. A worker with rich family coverage at a large employer often delays Part B. Someone at a 10-person shop usually doesn't.
