Medicare late penalties: how Part B and Part D fees stick

Bellevue, Neb. — Missing a Medicare deadline can quietly cost you for the rest of your life. The late-enrollment penalties for Part B (doctor visits) and Part D (prescription drugs) don't just show up once — they're added to your monthly premium for as long as you have that coverage. The good news: if you understand the timing, the penalties are almost always avoidable.

Here's how each penalty works, who is at risk in Bellevue and Sarpy County, and the simple steps to protect yourself.

Why these penalties exist

Medicare is built on the idea that healthy and less-healthy people share the risk pool together. If people could wait until they got sick to sign up, premiums would climb for everyone. The late-enrollment penalties are Medicare's way of encouraging people to enroll on time — or to keep other coverage that's at least as good until they do.

That means the penalties aren't a punishment for forgetting a form. They're a permanent adjustment to your premium, so it pays to get the timing right the first time.

How the Part B penalty works

Your Initial Enrollment Period for Part B is a seven-month window: the three months before you turn 65, your birthday month, and the three months after. If you don't sign up during that window and you don't qualify for a Special Enrollment Period, you may owe a late fee.

The Part B penalty adds 10% to your standard Part B premium for every full 12 months you were eligible but didn't enroll. That amount is added to your premium for as long as you have Part B — in most cases, for life.

If you missed your window, you generally have to wait for the General Enrollment Period (January 1 – March 31) to sign up, with coverage starting the month after you enroll.

How the Part D penalty works

Part D works differently, but the idea is similar. If you go 63 days or more in a row without "creditable" prescription drug coverage after your Initial Enrollment Period ends, you can be charged a Part D late-enrollment penalty when you finally join a drug plan.

The math: Medicare multiplies 1% of the national base beneficiary premium by the number of full months you went without creditable coverage, then rounds to the nearest 10 cents. That amount is added to your Part D premium each month, for as long as you have Part D coverage.

"Creditable" simply means your drug coverage is expected to pay, on average, at least as much as standard Medicare drug coverage. Employer plans, union plans, and some VA and TRICARE coverage often qualify. Your plan is required to tell you each year whether your coverage is creditable — keep those notices.

How to avoid the penalties

Most Bellevue-area residents can sidestep these fees with a little planning:

• Mark your Initial Enrollment Period. It starts three months before your 65th birthday. Even if you plan to keep working, confirm what you need to do.
• If you're still working past 65, check with your employer's benefits office to see whether your health and drug coverage is creditable and whether you should still take Part A.
• If you lose employer coverage, you generally get a Special Enrollment Period to sign up for Part B and Part D without a penalty — but the clock is short, usually 8 months for Part B and 63 days for Part D.
• If you already owe a penalty, you can ask for a reconsideration if you believe it was applied in error, especially if you had creditable coverage you can document.

What's available locally

Bellevue is in Sarpy County, where Medicare beneficiaries can choose from Original Medicare plus a stand-alone Part D plan, or a Medicare Advantage plan that often includes drug coverage. The Annual Enrollment Period runs October 15 through December 7 each year, and the Medicare Advantage Open Enrollment Period runs January 1 through March 31. Those windows are for changing coverage — they don't erase a penalty already in place, but they're the right time to make sure you have the coverage you need going forward.

For 2026, Part D also has some important program-level protections worth knowing about: an annual out-of-pocket cap of $2,100, a maximum deductible of $615, and the optional Medicare Prescription Payment Plan, which lets you spread your drug costs across the year in monthly payments.
