Part B and Part D enrollment deadlines for Wylie residents

# Medicare late-enrollment penalties: how they work and how to avoid…

WYLIE, Texas — Missing a Medicare deadline can quietly add a surcharge to your monthly bill for the rest of your life. For folks here in Wylie approaching 65 — or already there and thinking about dropping employer coverage — the rules around Part B and Part D late-enrollment penalties are worth learning before a birthday or a job change sneaks up.

The good news: these penalties are almost always avoidable if you know the timing.

How the Part B penalty works

Part B covers doctor visits, outpatient care and many preventive services. If you don't sign up when you're first eligible — and you don't qualify for a Special Enrollment Period — Medicare adds 10% to your standard Part B premium for each full 12 months you delayed.

That surcharge isn't a one-time fee. In most cases, you pay it every month for as long as you have Part B. Someone who waits three full years, for example, could see a 30% permanent bump on top of the base premium.

You can generally sign up for Part B only during set windows: your Initial Enrollment Period, a Special Enrollment Period, or the General Enrollment Period (January 1 – March 31). Coverage from the General Enrollment Period starts the month after you sign up.

How the Part D penalty works

Part D is prescription drug coverage. The penalty here is calculated differently: 1% of the "national base beneficiary premium" for every month you were eligible for Part D but went without creditable drug coverage. "Creditable" means coverage that Medicare considers at least as good as a standard Part D plan — often employer, union or VA coverage.

That amount is rounded to the nearest 10 cents and added to your Part D premium each month, typically for as long as you have Part D. Because the national base premium can change year to year, your penalty can shift slightly too.

The Part D annual out-of-pocket cap on covered drugs is $2,100 in 2026 and $2,400 in 2027, and the maximum Part D deductible is $615 in 2026 and $700 in 2027. The coverage gap known as the "donut hole" has been eliminated since 2025, so drug coverage now runs in three simpler phases.

Who's exempt — and how Wylie workers can protect themselves

Many people in the Wylie area keep working past 65, often with employer health insurance through a Plano, Richardson or Dallas job. If your employer coverage is considered creditable and comes from a group of 20 or more employees, you generally can delay Part B and Part D without a penalty. When that coverage ends, you get a Special Enrollment Period to sign up.

A few tips to stay safe:

• Ask your employer or plan administrator, in writing, whether your drug coverage is creditable. Keep the notice.
• If you have retiree coverage, COBRA or VA benefits, check the rules — COBRA and most retiree plans do not count as active employer coverage for Part B purposes.
• Mark your Initial Enrollment Period on the calendar: the three months before your 65th birthday, your birthday month, and the three months after.

Local context for Wylie

Wylie sits in Collin County, where Medicare beneficiaries have a wide range of Original Medicare, Medicare Advantage and stand-alone Part D options to consider once they are enrolled. Availability and plan counts are set at the county level, not the city level, so two neighbors in Wylie see the same menu of choices — but the enrollment rules described above apply the same way everywhere in the country.

The Annual Enrollment Period (October 15 – December 7) and the Medicare Advantage Open Enrollment Period (January 1 – March 31) are for switching or changing plans — they generally don't erase a late-enrollment penalty you've already accrued.

Where to get personal help

Because penalties depend on your exact timeline — when you turned 65, when your job coverage ended, whether it was creditable — it pays to talk with someone who can look at your paperwork.
