Missed Medicare Enrollment in Ohio: Your Options

If you missed your Initial Enrollment Period, you can still sign up during the General Enrollment Period — January 1 to March 31 each year — and coverage now begins the month after you enroll, not in July. You may owe a late-enrollment penalty, but not always: if you had creditable coverage during the gap, or you qualify for a Special Enrollment Period, the penalty does not apply.

Before anything else: check whether you actually missed it. A surprising number of the people who call me believing they are late are not. If you had health coverage through a job — yours or a spouse’s — during the gap, you may have a Special Enrollment Period and owe nothing.

I am Steve Almeroth, an independent Medicare broker in Middleburg Heights, and this page walks through both cases honestly, including the bad one.

First: are you actually late?

Work through these before assuming a penalty.

Did you have coverage through current employment during the gap? Yours or a spouse’s, at an employer with 20 or more employees. If so, you likely have an 8-month Special Enrollment Period rather than a penalty. See Still Working at 65 in Ohio.

Was it COBRA or retiree coverage? Then no — neither counts as current employment, and neither extends your window. This is the most common way people end up genuinely late.

Did something unusual happen? Medicare grants Special Enrollment Periods for certain situations, including some cases where you were given incorrect information by an employer or a health plan. These are case-by-case and require documentation, but they exist. If you were actively misinformed, say so when you call Social Security.

Are you eligible for a Medicare Savings Program? If your income and assets are limited, Ohio’s Medicare Savings Programs may pay your Part B premium — and enrolling in one can open its own enrollment path. See Medicare Assistance Programs.

The General Enrollment Period

If you are genuinely late, this is the path.

This changed in 2023, and stale information is everywhere. Under the old rules, General Enrollment Period coverage did not begin until July 1 — so someone enrolling in January waited six months. Section 120 of the Consolidated Appropriations Act, 2021 replaced that: coverage now begins the month after enrollment. If you find a page or a printed booklet saying “July 1,” it is out of date, including some booklets still in circulation.

Once you have Part B, you can then add a Part D drug plan or a Medicare Advantage plan.

How the penalties actually work

Two separate penalties. Both are permanent, and both are calculated on published national figures rather than on anything specific to you.

Part B

10% added for each full 12-month period you could have had Part B and didn’t.

CMS’s own 2026 example: someone who waited two full years pays 20% extra. Against the 2026 standard premium of $202.90, that is $202.90 + $40.58 = $243.50 per month, rounded to the nearest ten cents. You pay it for as long as you have Part B.

Note “full 12-month period.” Eleven months late is a 0% penalty. Thirteen months is 10%, not 13%.

Part D

1% of the national base beneficiary premium for every full month without creditable drug coverage. The base figure is $38.99 in 2026.

It is triggered by going 63 or more days in a row without creditable drug coverage after your Initial Enrollment Period ends. CMS’s example: 17 uncovered months works out to 0.17 × $38.99 = $6.60 per month, added to whatever your drug plan costs.

Two things people find counterintuitive. The penalty follows you even if you switch to a plan with no premium — you pay the penalty on top of $0. And because it is indexed to the national base premium, it moves each year.

Part A

Most people get Part A premium-free and this never applies. If you have to buy Part A, the penalty is 10%, and you pay it for twice the number of years you delayed — not for life.

What waives a penalty

Creditable coverage during the gap. This is the main one. Coverage through current employment at an employer with 20+ employees, for Part B; drug coverage at least as good as Medicare’s, for Part D. Your Notice of Creditable Coverage is the proof, and you will likely need form CMS-L564 signed by the employer.

Qualifying for a Special Enrollment Period. If one applies, you are not late at all.

Extra Help (the Part D Low-Income Subsidy). If you qualify, the Part D late-enrollment penalty is eliminated. This is worth checking carefully — many people who qualify never apply. See Medicare Assistance Programs.

A successful appeal. You can request reconsideration of a penalty determination, and it is worth doing when you were misinformed by an employer or a plan and can document it. It is a real process with a real success rate, not a formality — but it needs evidence.

The Ohio wrinkle: your Medigap window still opens

Here is genuinely good news that people in this situation often do not know.

Your Medicare Supplement (Medigap) open enrollment is the six months beginning the first month you are both 65 or older and enrolled in Part B. It is keyed to when Part B starts — not to whether you enrolled on time. So if your Part B begins in April after a General Enrollment Period sign-up, your protected Medigap window runs April through September, and during it no insurer can decline you or rate you on your health. That is Ohio Administrative Code Rule 3901-8-08.

Being late for Part B does not cost you the Medigap window. But do not waste it. Ohio has no “birthday rule” and no annual guaranteed-issue period, so once those six months pass, every supplement application here is medically underwritten. For someone who has just spent a year or more uninsured, that matters — a diagnosis in the gap can make you uninsurable afterward.

Compare the two paths in Medigap vs Medicare Advantage in Ohio.

What to do now

1. Establish whether you had creditable coverage during the gap. Call former employers now, while people still remember you. Get the CMS-L564 signed.
2. Call Social Security at 1-800-772-1213 and ask them to confirm your enrollment status and any penalty determination in writing.
3. Mark January 1. If the General Enrollment Period is your path, enrolling on January 2 rather than March 30 gets your coverage started two months earlier.
4. Plan the Medigap window before Part B starts, not after.

Common questions

Is the penalty really for life? For Part B, yes, in almost all cases. For Part D, for as long as you have drug coverage. Part A’s is time-limited.

Can I avoid the penalty by skipping Part B entirely? You avoid the penalty and keep the exposure. Without Part B you have no outpatient coverage — no doctor visits, no outpatient surgery, no chemotherapy, no durable medical equipment. And the penalty grows the longer you wait, so the arithmetic gets worse, not better.

I’m on Medicaid. Does this apply? Different rules, and generally better ones. Ohio’s Medicare Savings Programs can cover the Part B premium, and enrollment is handled differently. Get specific advice.

Will a broker help me if I’m late and there’s no sale in it? This one is mostly paperwork and Social Security, and there is no commission in it. I still take the call — it is a bad time for people and the answers are not obvious.
