How Gulfport residents can avoid Medicare late-enrollment fees

In Gulfport, turning 65 comes with a stack of Medicare mail — and a few deadlines that can quietly cost you money for the rest of your life. The most common trap? Missing your sign-up window for Part B (doctor visits) or Part D (prescription drugs). Both parts carry late-enrollment penalties that don't just add up once. They stick to your monthly premium for as long as you have coverage.

The good news: these penalties are almost entirely avoidable if you know the rules.

How the Part B 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 Part B premium for each full 12-month period you delayed. That higher premium usually stays with you for as long as you're enrolled in Part B.

Example: If you waited three full years to sign up, your premium could be 30% higher — every month, for life.

Most people become eligible during their Initial Enrollment Period, a seven-month window that starts three months before the month you turn 65 and ends three months after.

How the Part D penalty works

The Part D penalty works differently but the idea is similar. If you go 63 days or more in a row without Medicare drug coverage or other "creditable" drug coverage after you're first eligible, you can be charged a penalty when you finally enroll.

The math: Medicare multiplies 1% of the "national base beneficiary premium" by the number of months you were uncovered, rounds to the nearest 10 cents, and adds it to your Part D premium. Like the Part B penalty, it generally lasts as long as you have Part D.

What "creditable coverage" means

You don't get penalized just for delaying — you get penalized for going without coverage that Medicare considers as good as its own. This is called creditable coverage.

Common examples include:

• Group health insurance from a current employer (yours or your spouse's)
• Some union or retiree plans
• TRICARE or VA drug coverage (for Part D purposes)

Each fall, your drug plan or employer plan should send a Notice of Creditable Coverage. Save it. If Medicare ever asks why you delayed enrolling, that letter is your proof.

How Gulfport residents can stay on track

Gulfport is in Harrison County, where seniors have a healthy number of stand-alone Part D plans and Medicare Advantage plans with drug coverage to choose from during enrollment periods. That's helpful — but the choice itself doesn't matter if you miss the sign-up window.

A few simple steps:

1. Mark your Initial Enrollment Period on the calendar the year you turn 65. 2. If you're still working past 65, ask your HR department in writing whether your health and drug coverage are creditable for Medicare. 3. When employer coverage ends, you generally have an 8-month Special Enrollment Period for Part B and 63 days for Part D — don't wait. 4. During the Annual Enrollment Period (Oct. 15 – Dec. 7), review your drug plan even if you like it. Formularies and pharmacies change every year.

A few 2027 numbers worth knowing

Even outside of penalties, Medicare has some new figures worth keeping in mind:

• Part D out-of-pocket costs are capped at $2,100 in 2026.
• The Part D deductible can be no more than $615.
• The coverage gap (the old "donut hole") was eliminated in 2025, so Part D now has three phases instead of four.
• The Medicare Prescription Payment Plan lets you spread drug costs across the year in monthly payments — no interest, no fees.
• IRMAA income-related surcharges begin above $109,000 in income for a single filer in 2026.

None of these change the penalty rules, but they're the backdrop for any decision you make about drug coverage.
