How Dallas Medicare Enrollees Can Avoid Part B, Part D Fees

DALLAS, Texas — Missing a Medicare deadline can cost you every single month, for as long as you have coverage. That's the part many people don't hear about until it's too late.

Late-enrollment penalties for Part B (doctor visits and outpatient care) and Part D (prescription drugs) are added to your monthly premium — often for life. The good news: with a little planning, most people can avoid them entirely. Here's how the rules work, and what to watch for if you live in Dallas or anywhere else.

Why late penalties exist

Medicare is built on the idea that most people enroll when they first become eligible — usually around their 65th birthday. When someone waits without a good reason, Medicare adds a penalty to encourage timely sign-ups and keep the risk pool balanced.

The penalty isn't a one-time fine. It's added to your premium month after month, and in most cases it stays with you.

The Part B late-enrollment penalty

If you don't sign up for Part B when you're first eligible — and you don't have other qualifying coverage, like a job-based health plan through active employment — you may face a 10% increase in your Part B premium for every full 12 months you could have had Part B but didn't.

A few key points:

• The penalty is added to the standard Part B premium each month.
• It usually lasts for as long as you have Part B.
• Your Initial Enrollment Period is a 7-month window: the 3 months before your 65th birthday month, your birthday month, and the 3 months after.
• If you miss it, the General Enrollment Period runs January 1 – March 31 each year, with coverage starting the month after you enroll.

If you kept working past 65 and had employer coverage through your job (or your spouse's job), you likely qualify for a Special Enrollment Period to sign up for Part B without a penalty — but you have to act within 8 months of that job-based coverage ending.

The Part D late-enrollment penalty

The Part D penalty works differently. It applies if you go 63 or more days in a row without either a Part D plan or other "creditable" prescription drug coverage (coverage that Medicare considers at least as good as a standard Part D plan) after your Initial Enrollment Period ends.

The amount is calculated by multiplying 1% of the "national base beneficiary premium" by the number of full months you went without creditable drug coverage. That amount is then added to your Part D premium — and, like Part B, it generally stays with you.

If you have drug coverage through an employer, union, or the VA, ask the plan administrator for a Notice of Creditable Coverage. Keep it. That paperwork is what proves you don't owe a penalty later.

How to avoid the penalties

The simplest path:

1. Mark your Initial Enrollment Period. Sign up for Part A, Part B, and either a Part D drug plan or a Medicare Advantage plan that includes drug coverage during that 7-month window. 2. If you're still working, confirm in writing that your employer coverage is creditable. Then use your Special Enrollment Period when that coverage ends. 3. Don't go more than 63 days without creditable prescription drug coverage once you're Medicare-eligible. 4. Use the Annual Enrollment Period, October 15 – December 7, to review or change Part D and Medicare Advantage coverage for the following year.

What's available in Dallas

Dallas is in Dallas County, where Medicare beneficiaries have a range of stand-alone Part D plans and Medicare Advantage plans (which often include drug coverage) to choose from. Plan availability is set at the county level by the Centers for Medicare & Medicaid Services (CMS), so two neighbors in the same ZIP code will generally see the same menu of options.

You can compare what's offered in your county using the Plan Finder at Medicare.gov.

A few 2027 numbers worth knowing

While you're thinking about enrollment, keep these program-level figures in mind for 2026:

• $2,100 in 2026 ($2,400 in 2027) — the new out-of-pocket cap on covered Part D drug costs.
• $615 in 2026 ($700 in 2027) — the maximum Part D deductible a plan can charge.
• The coverage gap ("donut hole") is gone as of 2025; Part D now has three phases.
• The Medicare Prescription Payment Plan lets you spread your drug costs across the year in monthly installments, at no extra charge.
• IRMAA income-related surcharges for Part B and Part D begin above $109,000 in income for a single filer in 2026.
