Key takeaways

Your Initial Enrollment Period is seven months long: the three months before your 65th birthday month, your birthday month, and the three months after.
Signing up in the three months before your birthday month means your Medicare coverage can start the first day of your birthday month.
Valley Stream is in Nassau County, where residents can compare all available Medicare options at medicare.gov or by calling 1-800-MEDICARE.
Free one-on-one help is available through New York's State Health Insurance Assistance Program (HIICAP), which does not sell plans.

Here's how the window works, what to do first, and where Valley Stream residents can get free, unbiased help.

The seven-month window, explained

Your Initial Enrollment Period (IEP) starts three months before the month you turn 65 and ends three months after. That's seven months total.

When you sign up matters. If you enroll in any of the three months before your birthday month, your Part A and Part B coverage can begin the first day of your birthday month. If you wait until your birthday month or later, your coverage start date is pushed back — sometimes by a month or more.

For a Valley Stream resident with an April birthday, for example, the window opens January 1 and closes July 31.

First step: decide about Part A and Part B

Original Medicare has two pieces:

Part A covers hospital stays. Most people pay no premium for it because they (or a spouse) paid Medicare taxes while working.
Part B covers doctor visits and outpatient care. It has a monthly premium set by the federal government.

If you're already getting Social Security benefits before 65, you're usually enrolled in both automatically. If you're not, you'll need to sign up yourself at ssa.gov or your local Social Security office.

Still working? Don't skip this check

If you or your spouse are still working at 65 and have health coverage through that job, the rules get more specific. Some people delay Part B without penalty; others should sign up on time to avoid gaps. Employer size matters, and so does the type of coverage.

Before you decide, talk to your employer's benefits office and confirm in writing whether your coverage counts as "creditable" for Medicare purposes. This one conversation can save you from a lifelong late-enrollment penalty.

Then think about drug coverage and the rest

Once you've handled Part A and Part B, you'll want to think about prescription drug coverage (Part D) and whether you want to stay with Original Medicare or choose a Medicare Advantage plan (Part C).

A few 2027 program-level facts worth knowing:

Part D has a $2,400 annual out-of-pocket cap on covered drugs in 2027 (up from $2,100 in 2026).
The Part D deductible can be no higher than $700 in 2027.
The old "donut hole" coverage gap was eliminated in 2025 — Part D now has three phases.
If you have high drug costs, the Medicare Prescription Payment Plan lets you spread those costs into monthly payments instead of paying at the pharmacy counter.
Higher-income beneficiaries pay an IRMAA surcharge, which begins above $109,000 in income for a single filer in 2026.

Valley Stream is in Nassau County, and plan availability — how many Medicare Advantage and Part D plans you can choose from — is set at the county level. You can see the full list for your ZIP code using the Plan Finder at medicare.gov.

Watch these penalties

Two late-enrollment penalties trip up new beneficiaries most often:

Part B penalty: 10% added to your premium for each full 12-month period you were eligible but didn't sign up (and didn't have qualifying job coverage). It usually lasts as long as you have Part B.
Part D penalty: 1% of the national base premium for every month you went without creditable drug coverage after becoming eligible. It's also generally permanent.

These are the main reason the seven-month window matters so much.

Where Valley Stream residents can get free help

You don't have to figure this out alone, and you don't have to talk to a salesperson to get answers.

Medicare.gov and 1-800-MEDICARE (1-800-633-4227) are the official federal resources.
HIICAP — New York's State Health Insurance Assistance Program — offers free, one-on-one counseling. Nassau County residents can reach the local office through the Nassau County Office for the Aging.
The Social Security Administration handles the actual enrollment in Part A and Part B.

Frequently asked questions

When exactly does my Initial Enrollment Period start?

It starts on the first day of the month three months before you turn 65 and ends on the last day of the third month after your birthday month — seven months in all. If your birthday is on the first of the month, Medicare treats you as turning 65 the previous month, which shifts the window one month earlier.

What if I miss my Initial Enrollment Period?

You'll generally have to wait until the General Enrollment Period, which runs January 1 through March 31, and coverage begins the month after you enroll. You may also owe a Part B late-enrollment penalty. Some people qualify for a Special Enrollment Period if they had job-based coverage — check with Social Security before assuming you're stuck waiting.

Do I need to sign up for Medicare if I'm still working and have employer coverage?

Not always, but you need to confirm the details. If your employer has 20 or more employees, you can usually delay Part B without penalty. Smaller employers, retiree coverage, and COBRA all follow different rules, so ask your benefits office and, if you're unsure, call HIICAP or Medicare before your birthday month.

Where do I actually sign up?

Enrollment in Part A and Part B goes through the Social Security Administration — online at ssa.gov, by phone, or at a local office. Part D and Medicare Advantage enrollment happens at medicare.gov once you have your Medicare number. ## Getting started Turning 65 in Valley Stream doesn't have to be complicated, but it does reward planning ahead. Mark the start of your seven-month window on the calendar, gather your questions, and use the official resources: medicare.gov, 1-800-MEDICARE, the Social Security Administration, and Nassau County's HIICAP counselors. They're free, they don't sell anything, and they exist for exactly this moment.
