Newport Beach guide to Medicare Part B and Part D penalties that can follow you for life

NEWPORT BEACH, Calif. — Two of the most expensive mistakes in Medicare are quiet ones. Miss your window to sign up for Part B or Part D, and the extra charge you owe can stay on your bill for as long as you have the coverage. The good news: once you know how the timing works, both penalties are usually avoidable.

Why these deadlines matter more than most

Medicare has a lot of dates, but Part B and Part D are the two where a missed sign-up can follow you for the rest of your life. Unlike a one-time fee, these penalties get added to your monthly premium, month after month, year after year.

That's why it's worth understanding the rules before your 65th birthday — or before you retire, if that comes later.

How the Part B late-enrollment penalty works

Part B covers doctor visits, outpatient care, and many preventive services. Most people are first eligible during their Initial Enrollment Period (IEP) — the seven-month window that starts three months before the month you turn 65 and ends three months after.

If you don't sign up when you're first eligible, and you don't qualify for a Special Enrollment Period, here's what can happen:

• Your Part B premium can go up 10% for every full 12-month period you could have had Part B but didn't.
• That higher premium generally lasts for as long as you have Part B.

So a two-year delay isn't a one-time bump. It's a 20% higher premium, every month, for life.

How the Part D late-enrollment penalty works

Part D is prescription drug coverage. The penalty here is smaller month to month, but it works the same way — it sticks.

You may owe a Part D penalty if you go 63 days or more in a row without one of these after you're first eligible:

• A Medicare Part D plan
• A Medicare Advantage plan that includes drug coverage
• Other "creditable" drug coverage (for example, from an employer or union plan that's at least as good as Medicare's)

The penalty is roughly 1% of the "national base beneficiary premium" for each full month you went without coverage, rounded to the nearest 10 cents, added to your Part D premium. It's recalculated each year as the base premium changes, and it usually lasts as long as you have Part D.

The main way to avoid a penalty: use your Special Enrollment Period

Many people at 65 are still working and covered by a job-based health plan — either their own or a spouse's. If that coverage counts as creditable, you generally don't have to sign up for Part B or Part D right away.

When the job coverage ends, you typically get a Special Enrollment Period (SEP) to enroll without a late penalty. For Part B, that window is usually up to 8 months after the employer coverage or job ends. For Part D, it's usually 63 days.

Two tips that save people a lot of trouble:

1. Ask your employer or plan for a "creditable coverage" notice in writing. For Part D especially, you may need to prove your old coverage was creditable. 2. Don't rely on COBRA or retiree coverage to keep the clock from ticking. COBRA is generally not considered active employer coverage for Part B purposes, even though you're still insured.

If you're not sure whether your situation qualifies, ask before you assume.

What if you already owe a penalty?

If Medicare tells you that you owe a late-enrollment penalty, you have the right to ask for a review, sometimes called a reconsideration. This is the process to use if you believe your prior coverage was creditable, or that you had a valid reason you weren't told about the rules.

The notice you receive will explain how to request a review and the deadline to do it. Don't ignore that letter — the timelines are short.
