Key takeaways

  • Your Initial Enrollment Period runs seven months: 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 coverage can start the first day of your birthday month.
  • Missing your IEP without other creditable coverage can trigger lifelong late-enrollment penalties for Part B and Part D.
  • Free, unbiased help is available through Washington's SHIBA program (Washington's SHIP) and at medicare.gov.

ISSAQUAH, Wash. — For people in Issaquah approaching their 65th birthday, the road into Medicare starts with one important calendar: the Initial Enrollment Period, or IEP. It's a seven-month window that can shape your coverage — and your costs — for years to come. Miss it, and you could face late penalties that follow you for life.

The good news? A little planning goes a long way. Here's what to know before the mail from Medicare starts arriving.

What the Initial Enrollment Period actually is

Your IEP is a seven-month window built around your 65th birthday. It includes the three months before the month you turn 65, the month itself, and the three months after. For most people in Issaquah, this is the first chance to enroll in Medicare Part A (hospital) and Part B (medical).

If you're already receiving Social Security benefits, you'll likely be enrolled in Parts A and B automatically. If you're not, you'll need to sign up yourself through the Social Security Administration at ssa.gov or by calling 1-800-772-1213.

Why timing inside the window matters

Not all seven months are equal. Enrolling in the first three months of your IEP means your Medicare coverage can begin the first day of your birthday month. Wait until your birthday month or later, and your start date gets pushed back — sometimes by a full month or more.

That gap can matter if you're planning to leave an employer plan, schedule a surgery, or start a new prescription. Signing up early is the simplest way to avoid a coverage gap.

The penalties for waiting

Medicare's late-enrollment penalties are one of the most common — and most painful — mistakes new beneficiaries make.

If you're still working at 65 and covered by a large employer's health plan, you may be able to delay Part B without penalty. Confirm this with your benefits administrator before you make a decision.

First steps to take right now

Even if your birthday is still months away, a few early moves can save you headaches:

1. Create a my Social Security account at ssa.gov to check your enrollment status and start dates. 2. Ask your employer or retiree plan in writing whether your current drug coverage is "creditable" for Part D purposes. 3. Learn the parts: Original Medicare (Parts A and B), Part D drug plans, Medigap supplemental policies, and Medicare Advantage (Part C) all work differently. 4. Check availability locally. Issaquah is in King County, where a wide range of Medicare Advantage and Part D plans are offered each year. Plan choices, networks, and pharmacy lists change annually, so review before you enroll.

Key 2027 numbers worth knowing

Even outside your IEP, some program-level figures are helpful context as you compare coverage:

Frequently asked questions

When exactly does my Initial Enrollment Period start and end?
It begins three months before the month you turn 65 and ends three months after your birthday month — seven months total. For example, if your birthday is in June, your IEP runs from March 1 through September 30.
Do I have to sign up for Medicare at 65 if I'm still working?
Not always. If you have health coverage through a current employer with 20 or more employees, you may be able to delay Part B and Part D without a penalty. Confirm your situation with your HR department and Social Security before deciding.
What's the difference between the IEP and the Annual Enrollment Period?
The IEP is your one-time window when you first become eligible for Medicare. The Annual Enrollment Period (October 15 – December 7) is when anyone already on Medicare can switch, add, or drop Medicare Advantage and Part D coverage for the following year.
