Oak Lawn at 65: how to work your 7-month Medicare window without a misstep

Turning 65 in Oak Lawn comes with a Medicare deadline most people have never had to think about before — a seven-month sign-up window built around your birthday month. Miss it, and you could face lifelong late penalties or a gap in coverage. Use it well, and you can start Medicare on time with the pieces that fit your life.

Here is how the Initial Enrollment Period works, and the first decisions to make as a new Oak Lawn enrollee.

What the Initial Enrollment Period actually is

The Initial Enrollment Period (IEP) is the seven-month window around your 65th birthday when you can first sign up for Medicare. It includes the three months before your birthday month, your birthday month, and the three months after.

When you enroll matters. If you sign up in the three months before you turn 65, your coverage generally starts the first day of your birthday month. If you sign up during or after your birthday month, coverage starts the month after you enroll. That can leave a short gap, so most people aim to enroll early in the window.

Do you have to sign up, or does it happen for you?

It depends on whether you are already getting Social Security or Railroad Retirement Board benefits.

• If you are already collecting those benefits, you will usually be enrolled in Part A and Part B automatically, and your red, white and blue card will arrive in the mail before your 65th birthday.
• If you are not yet collecting Social Security — which is common for people still working at 65 — you have to sign up yourself through the Social Security Administration at ssa.gov or by calling Social Security.

If you plan to delay Social Security to grow your benefit, put a reminder on your calendar three months before your 65th birthday to enroll in Medicare on its own.

Still working at 65? Read this carefully.

Many Oak Lawn residents are still working — or covered under a spouse's job — when they turn 65. What you do next depends on the size of that employer.

• If the employer has 20 or more employees, its plan generally stays primary, and you can often delay Part B without a late penalty. You will get a Special Enrollment Period to sign up later when the job coverage ends.
• If the employer has fewer than 20 employees, Medicare usually becomes primary at 65, and delaying Part B can leave you underinsured. Most people in that situation should enroll on time.
• Retiree coverage, COBRA and marketplace plans are not considered active employer coverage for this rule. If those are what you have, enroll in Medicare during your IEP.

When in doubt, ask your HR or benefits office in writing how your plan coordinates with Medicare.

The first decisions to make

Once you have Part A and Part B (Original Medicare) squared away, three choices come next:

1. Drug coverage (Part D). Even if you take no prescriptions today, signing up for a stand-alone Part D plan or a Medicare Advantage plan that includes drugs helps you avoid a late-enrollment penalty later. In 2026, Part D has a $2,100 annual out-of-pocket cap, a maximum deductible of $615, and the old "donut hole" is gone — replaced by a simpler three-phase design. There is also a new Medicare Prescription Payment Plan that lets you spread drug costs across the year in monthly installments. 2. Original Medicare plus a Medigap policy, or a Medicare Advantage plan. Original Medicare pays for most Part A and B services but has no yearly out-of-pocket limit; that is why many people pair it with a Medigap (supplement) policy. Medicare Advantage plans bundle Part A, Part B and usually Part D into one plan with its own network and rules. Oak Lawn is in Cook County, where many Advantage and Part D plans are sold, so it is worth comparing. 3. Whether IRMAA applies to you. Higher-income enrollees pay an Income-Related Monthly Adjustment Amount on top of Part B and Part D premiums. For 2026, IRMAA starts above $109,000 in income for a single filer (based on your tax return from two years earlier).

Medigap: the Oak Lawn timing question

If you think you will want a Medigap policy, timing matters. Your six-month Medigap Open Enrollment Period begins the month your Part B starts and you are 65 or older. During that window, Illinois insurers must sell you any Medigap policy they offer at their best available rate, regardless of your health history. After it ends, medical underwriting can apply, and pre-existing conditions may make a policy harder or more expensive to get.

After you enroll: what comes next

Your Initial Enrollment Period is a one-time event, but Medicare keeps giving you chances to adjust:

• The Annual Enrollment Period runs October 15 – December 7 every year. You can join, switch or drop a Medicare Advantage or Part D plan.
• The Medicare Advantage Open Enrollment Period runs January 1 – March 31 for people already in an Advantage plan who want to switch once.

Review your coverage every fall. Plans change, drug lists change, and your health needs change too.
