Turning 65 in Ohio

If you do one thing after reading this page, make it this: start about three months before the month you turn 65. Almost every expensive Medicare mistake I see traces back to somebody starting late.

Your seven-month window

The Initial Enrollment Period runs for seven months in total: the three months before your birthday month, your birthday month itself, and the three months after.

Those halves are not equal. Enrolling during the three months before your birthday month is what gets your coverage active on the first day of your birthday month. Enrolling during or after your birthday month pushes your start date back, which can leave you with a gap in coverage at exactly the moment your employer plan may be ending.

The checklist

1. Confirm whether you are enrolled automatically. If you are already drawing Social Security benefits, you are generally enrolled in Parts A and B automatically and your card arrives in the mail. If you are not drawing benefits yet, nothing happens on its own and you must actively enroll through Social Security.
2. Decide about Part B if you are still working. This depends on the size of your employer and the kind of coverage you have. See the section below — getting this wrong is expensive in both directions.
3. Write down every prescription. Name, dose, and how often. This single list determines more about your costs than any other piece of information.
4. Write down every doctor. Primary care, every specialist, and your preferred hospital system.
5. Choose your road. Original Medicare with a Supplement and a Part D plan, or a Medicare Advantage plan. Compared here.
6. Enroll, and get confirmation. Keep the confirmation number and your effective date somewhere you can find it.
7. Put a note in your calendar for October. Every year, Annual Enrollment runs October 15 to December 7, and every year your plan can change.

If you are still working at 65

This is the most common source of genuine confusion, and the right answer depends mainly on how many employees your employer has.

Do not guess at this one. Ask your HR department for written confirmation of whether your coverage is creditable, and call me before you decide to delay anything.

The penalties, plainly

Part B late enrollment penalty. If you do not enroll when first eligible and have no qualifying employer coverage, your Part B premium is increased permanently — the longer you waited, the larger it is. It does not expire.

Part D late enrollment penalty. Going 63 days or more without creditable drug coverage after eligibility adds a permanent amount to your Part D premium. People who take no medications at 65 often skip drug coverage entirely, and this is precisely how they get caught — the penalty follows them for life once they finally need a prescription.

Both are completely avoidable with correct timing. Neither can be appealed away afterwards in ordinary circumstances.

The decision that is hard to reverse

When you first enroll in Part B at 65, you get a one-time Medigap Open Enrollment window in which a Medicare Supplement must be issued to you regardless of your health history. No questions about your diagnoses, no declines.

Once that window closes, buying a Supplement in Ohio generally means medical underwriting outside of specific guaranteed-issue situations — and a carrier may decline you or charge more based on your health. So if you choose a Medicare Advantage plan at 65 and later decide you want the freedom of a Supplement, that move is not guaranteed to be available.

It runs the other way too: going from a Supplement to an Advantage plan is generally easy at the right time of year. That asymmetry is worth understanding before you pick, and it is the part of the conversation I spend the most time on.
