Part B and Part D late penalties explained for Normal residents

NORMAL, Ill. — For folks turning 65 in McLean County, one of the biggest Medicare mistakes has nothing to do with picking a plan. It's missing a deadline. Sign up late for Part B (doctor visits) or Part D (prescription drugs) without the right coverage in place, and Medicare can add a penalty to your premium for as long as you have the coverage — in many cases, for the rest of your life.

Here's what Normal residents need to know about those deadlines, how the penalties work, and how to steer clear of them.

The deadlines that matter most

Most people become eligible for Medicare at 65. Your Initial Enrollment Period (IEP) is a 7-month window: the 3 months before your birthday month, your birthday month, and the 3 months after.

If you miss that window and don't qualify for a Special Enrollment Period (for example, because you had job-based coverage from an employer with 20 or more employees), you may have to wait for the General Enrollment Period, which runs January 1 through March 31 each year. Coverage then begins the month after you sign up — and by that point, a late penalty may already be attached.

The Medicare Annual Enrollment Period (October 15 – December 7) and the Medicare Advantage Open Enrollment Period (January 1 – March 31) are for changing plans, not for first-time enrollment in Parts A and B.

How the Part B late penalty works

If you don't sign up for Part B when you're first eligible, and you don't have other qualifying coverage, Medicare adds 10% to your standard Part B premium for every full 12-month period you could have had it but didn't.

That surcharge doesn't go away. In most cases, you pay it for as long as you have Part B. Someone who delayed three full years, for example, could pay 30% more every month — for life.

The good news: if you're still working past 65 and covered by a large employer's health plan, you generally can delay Part B without a penalty and sign up later during a Special Enrollment Period.

How the Part D late penalty works

The Part D penalty works differently but stings the same way. If you go 63 days or more in a row without creditable prescription drug coverage after you first become eligible, Medicare can charge a permanent late-enrollment penalty when you finally sign up.

The math: Medicare multiplies 1% of the "national base beneficiary premium" by the number of full months you went without coverage, rounds it, and adds it to your monthly Part D premium. Because that base premium can change from year to year, your penalty amount can shift too — but it stays with you.

"Creditable coverage" simply means drug coverage that Medicare considers at least as good as a standard Part D plan. Employer plans, union plans, VA coverage, and TRICARE often qualify. Your plan is required to send you a notice each year telling you whether it counts — save those notices.

What's changing under the hood in 2027

Even if you're not worried about penalties right now, a few program facts are worth knowing as you weigh your enrollment timing:

• Part D out-of-pocket cap: $2,100 in 2026 and $2,400 in 2027. Once you hit it, you pay nothing for covered drugs the rest of the year.
• Part D maximum deductible: $615 in 2026 and $700 in 2027.
• The coverage gap ("donut hole") is eliminated as of 2025, replaced by a simpler three-phase design.
• Medicare Prescription Payment Plan: an optional program that lets you spread your drug costs into monthly payments instead of paying at the pharmacy counter.
• IRMAA (higher premiums for higher earners) begins above $109,000 in income for single filers in 2026.

The local picture in Normal

Normal is in McLean County, where Medicare plan availability — including Medicare Advantage and stand-alone Part D drug plans — is set at the county level. The number of plans and carriers offered here changes each year, so if you're weighing when to enroll, it's worth checking what's currently available in McLean County using the Plan Finder at Medicare.gov.

Availability is not the same as suitability. What matters for avoiding penalties is simply that you have some form of creditable coverage in place, on time.

How to avoid the penalties — a simple checklist

1. Know your 7-month window. Mark the 3 months before your 65th birthday on the calendar now. 2. If you're still working, ask your HR department, in writing, whether your health plan is considered creditable for Part B and Part D purposes. 3. Keep the annual "Notice of Creditable Coverage" your drug plan sends you. It's your proof. 4. Don't let 63 days pass without drug coverage once your Medicare eligibility begins. 5. When in doubt, ask before you skip. A short call now beats a lifetime surcharge later.
