Columbus, Indiana Medicare IEP: three months before to three after

Turning 65 in Columbus is a milestone — and it comes with one of the most important paperwork windows of your life. Your Initial Enrollment Period (IEP) opens three months before the month you turn 65, includes your birthday month, and runs three months after. That's a seven-month stretch to make your first Medicare decisions without a late penalty.

Key takeaways

  • Your Initial Enrollment Period lasts seven months — the three months before your 65th birthday month, that month, and the three months after.
  • Signing up during the three months *before* your birthday month means your Medicare can start the month you turn 65.
  • 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, and the old "donut hole" is gone.
  • Columbus residents can get free, unbiased help from Indiana SHIP, Medicare.gov, or 1-800-MEDICARE before choosing coverage.

The good news: you don't have to figure it out alone, and you don't have to figure it out all at once. Here's a plain walk-through of what to do first, in what order, and where to get free local help.

Start with your seven-month window

Your IEP is built around your 65th birthday month. If you turn 65 in June, your window runs March 1 through September 30.

Here's the part people miss: when you enroll inside that window changes when your coverage starts. If you sign up during the three months before your birthday month, coverage begins the first day of your birthday month. If you wait until your birthday month or later, coverage can be delayed by up to a month after you sign up. Enrolling early is usually the smoother path.

Decide if you need to actively sign up

Some people are enrolled in Medicare automatically. Others have to take action.

Understand the parts before you pick anything

Medicare has four parts, and it helps to know what each one does before you shop.

Once you have Part A and Part B (Original Medicare), you'll decide whether to add a standalone Part D plan and possibly a Medigap supplement — or to go the Medicare Advantage route instead.

What's new for Part D in 2027

If prescription costs have worried you in the past, the Part D rules that took effect in 2026 carry forward with higher limits in 2027:

Higher earners should also know about IRMAA — an income-related surcharge on Part B and Part D premiums that starts above $109,000 in income for a single filer in 2026.

What Columbus residents can expect locally

Columbus is in Bartholomew County, and plan availability is set at the county level. That means every Medicare Advantage and Part D plan you can consider is one that's approved to sell in Bartholomew County. When you use the Plan Finder at Medicare.gov, enter your ZIP code and it will show you the specific menu available where you live.

We're not naming or ranking plans here — that's your call, based on your doctors, your prescriptions, and your budget. But knowing your options are county-based helps you tune out national ads that may not apply to you.

Frequently asked questions

When exactly should I sign up for Medicare if I'm turning 65?
The safest move is to enroll during the three months before your birthday month. That way your coverage starts the first day of the month you turn 65, with no gap. You can still enroll during your birthday month or the three months after, but your start date may be delayed.
Do I have to take Part B at 65 if I'm still working?
Not always. If you have health coverage through a current employer (yours or your spouse's) and that employer has 20 or more employees, you can usually delay Part B without a late penalty. Smaller employers and retiree plans work differently, so check with your benefits office and Social Security before you decide.
What happens if I miss my Initial Enrollment Period?
You may have to wait for the General Enrollment Period (January 1 – March 31) to sign up for Part B, and you could face a lifetime late-enrollment penalty added to your monthly premium. Part D has its own late penalty. This is why the seven-month window matters.
Where can I get help comparing plans in Columbus without a sales pitch?
Indiana SHIP offers free, confidential counseling and does not sell insurance. You can also call 1-800-MEDICARE or use the Plan Finder tool at Medicare.gov with your Columbus ZIP code to see what's available in Bartholomew County. Turning 65 doesn't have to be stressful. Give yourself time, use the official resources, and make the decision that fits your health and your budget — not someone else's sales quota.
