Why Lakewood Retirees Face Medicare Part B and D Penalties

Turning 65 in Lakewood comes with a lot of paperwork, and one piece of it matters more than most people realize: signing up for Medicare on time. Miss your window for Part B or Part D, and you could pay a penalty every month for as long as you have coverage. The good news? These penalties are almost always avoidable once you know the rules.

LAKEWOOD, Colo. — A missed deadline can follow you for life

Here's a plain-English guide to how the late-enrollment penalties work, who they affect, and how to sidestep them.

The Part B late-enrollment penalty

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 have other qualifying coverage — Medicare adds 10% to your Part B premium for every full 12-month period you could have had it but didn't.

That surcharge isn't a one-time fee. It sticks to your monthly premium for as long as you have Part B. Someone who waits three years, for example, would pay an extra 30% every month, essentially forever.

Your first chance to enroll is your Initial Enrollment Period: the seven months around your 65th birthday (three months before, your birthday month, and three months after). If you miss it, the General Enrollment Period runs January 1 – March 31 each year, with coverage starting the month after you sign up.

The Part D late-enrollment penalty

Part D is prescription drug coverage. If you go 63 days or more in a row without "creditable" drug coverage after you're first eligible, Medicare can add a penalty when you finally enroll.

The math is different from Part B: Medicare multiplies 1% of the "national base beneficiary premium" by the number of full months you went without coverage, then adds that amount to your Part D premium. Like the Part B penalty, it generally lasts as long as you have the coverage.

"Creditable coverage" is drug coverage that pays, on average, at least as much as standard Medicare drug coverage. Employer plans, union plans, and TRICARE often qualify. Your plan should send you a notice each year telling you whether your coverage counts — save those notices.

How to avoid a penalty in the first place

A few habits keep most people out of trouble:

• Mark your Initial Enrollment Period. It starts three months before the month you turn 65.
• Don't assume you're auto-enrolled. People already receiving Social Security usually are; everyone else has to sign up through the Social Security Administration.
• If you're still working past 65, check with your employer's benefits office. Group coverage from a company with 20 or more employees usually lets you delay Part B without penalty and gives you a Special Enrollment Period later. Smaller employers often work differently — ask before you decide.
• Keep your "creditable coverage" letters. They're your proof you didn't need Part D yet.
• Watch the 63-day rule for drug coverage. If you lose creditable drug coverage, don't wait months to pick up a Part D plan.

What's changing in 2026

The penalties themselves aren't going away, but the drug program around them keeps evolving. A few program-level facts to know for 2026:

• Part D has a $2,100 annual out-of-pocket cap on covered drugs.
• The Part D deductible can't be higher than $615.
• The old coverage gap ("donut hole") is gone as of 2025 — Part D now has three phases instead of four.
• The Medicare Prescription Payment Plan lets you spread your drug costs across the calendar year in monthly installments instead of paying big bills at the pharmacy counter.
• IRMAA — the income-based surcharge on Part B and Part D premiums — starts above $109,000 for a single filer in 2026.

These changes don't erase penalties for people who signed up late, but they make it more important than ever to actually have Part D in place.

Enrollment windows to remember

• Initial Enrollment Period: the 7 months around your 65th birthday.
• General Enrollment Period (Part B): January 1 – March 31.
• Annual Enrollment Period: October 15 – December 7 (for Medicare Advantage and Part D changes).
• Medicare Advantage Open Enrollment: January 1 – March 31 (for people already in a Medicare Advantage plan).
• Special Enrollment Periods: triggered by life events like losing job-based coverage, moving, or leaving a plan's service area.
