Why the Medicare IEP matters most in Las Vegas

LAS VEGAS, N.M. — If a 65th birthday is on the horizon, the most important Medicare date isn't October or December. It's the seven-month stretch built around the birthday month itself — the Initial Enrollment Period, or IEP. Miss it, and the road back can mean waiting, paying more, or both.

Here's a plain-language walkthrough for readers in Las Vegas and the rest of San Miguel County.

What the Initial Enrollment Period actually is

Your IEP is a seven-month window tied to your 65th birthday. It starts three months before the month you turn 65, includes your birthday month, and runs three months after. That's your first — and cleanest — chance to sign up for Medicare Part A (hospital) and Part B (medical), according to Medicare.gov.

If you enroll in the three months before your birthday month, coverage generally begins the first day of your birthday month. Sign up later in the window, and coverage starts the month after you enroll.

Why the window matters

Medicare is not automatic for everyone. If you're already receiving Social Security benefits before 65, you'll usually be enrolled in Parts A and B automatically. If you're not — which is more common now that people work longer — you have to sign yourself up through the Social Security Administration.

Skip your IEP without other qualifying coverage, and two things can happen:

• A late enrollment penalty for Part B, which can add 10% to your premium for each full year you were eligible but didn't sign up. That penalty typically sticks around for as long as you have Part B.
• A late enrollment penalty for Part D (prescription drug coverage) if you go 63 days or more without "creditable" drug coverage after becoming eligible.

These are the kinds of mistakes that are easy to avoid — and painful to fix later.

First steps to take before your birthday month

A simple checklist for people aging in:

1. Decide on Part B timing. If you or your spouse are still working and have solid employer coverage, you may be able to delay Part B without penalty using a Special Enrollment Period later. If not, plan to enroll during your IEP. 2. Create a "my Social Security" account at ssa.gov. That's where you'll sign up for Parts A and B if it isn't automatic. 3. Think about drug coverage. Part D is optional, but going without creditable coverage triggers a penalty later. The Part D out-of-pocket cap is $2,100 in 2026 and $2,400 in 2027; the maximum deductible is $615 in 2026 and $700 in 2027. The old "donut hole" coverage gap is gone as of 2025. 4. Choose your path: Original Medicare or Medicare Advantage. Original Medicare (Parts A and B) is the federal program, often paired with a standalone Part D plan and sometimes a Medigap policy. Medicare Advantage (Part C) is offered by private insurers approved by Medicare and bundles coverage together. 5. Check what's available locally. Las Vegas is in San Miguel County, where Medicare Advantage and Part D plan options are set at the county level. You can compare them at Medicare.gov's Plan Finder using your ZIP code and medication list.

A quick word on income and IRMAA

Higher-income enrollees pay an extra amount on top of the standard Part B and Part D premiums, called IRMAA. For 2026, IRMAA surcharges start above $109,000 in income for a single filer (and higher thresholds for joint filers). Social Security uses your tax return from two years earlier to decide, so a recent retirement or life change can sometimes be appealed.

After your IEP: the other dates to know

Your IEP happens once. After that, the calendar shifts to these annual windows:

• Annual Enrollment Period: Oct. 15 – Dec. 7 — anyone with Medicare can join, switch, or drop a Medicare Advantage or Part D plan.
• Medicare Advantage Open Enrollment: Jan. 1 – March 31 — people already in a Medicare Advantage plan can make one change.
• Special Enrollment Periods — triggered by life events like moving, losing employer coverage, or qualifying for Extra Help.

There's also a General Enrollment Period (Jan. 1 – March 31) for people who missed their IEP entirely. Coverage starts the month after you enroll, but late penalties may apply.

Small tools that can ease the cost

Two features worth knowing about as you set up drug coverage:

• The Medicare Prescription Payment Plan lets you spread your out-of-pocket drug costs across the calendar year in monthly payments instead of paying big amounts at the pharmacy counter. It's optional and free to opt into.
• Extra Help (the Low Income Subsidy) can lower drug plan costs for people who qualify by income and resources.
