Medicare Open Enrollment 2026 in Ohio: What to Review Before December 7

Medicare Annual Enrollment runs from October 15 to December 7 every year, and 2026 is no exception. If you have Medicare and live in Lebanon or anywhere in Warren County, this is the one window when you can change your Medicare Advantage or Part D drug plan for coverage that starts January 1, 2027. This guide covers when the window opens, what you can change, and the specific items worth checking before the deadline.

When is Medicare Open Enrollment in 2026?

Medicare Open Enrollment in 2026 runs from October 15 through December 7. This period is officially called the Annual Enrollment Period, or AEP. Any plan change you make during these weeks takes effect on January 1, 2027. Miss December 7 and, in most cases, you keep your current plan for another full year unless you qualify for a Special Enrollment Period.

What can you change during Medicare Annual Enrollment?

During the October 15 to December 7 window, you can make any of the following changes:

• Switch from Original Medicare to a Medicare Advantage plan, or from Medicare Advantage back to Original Medicare.
• Switch from one Medicare Advantage plan to another.
• Join a standalone Part D prescription drug plan, drop one, or switch to a different one.

You do not have to do anything during AEP. If you take no action, your current plan renews automatically. The risk is that your plan may not renew on the same terms, which is exactly why a yearly review matters.

Who should review their Medicare plan during open enrollment?

Every Medicare beneficiary should review their plan during open enrollment, but it matters most if any of these apply to you. Your prescriptions changed in the past year. You saw a new doctor or specialist and want to confirm they stay in network. You received an Annual Notice of Change letter from your plan describing higher premiums, copays, or deductibles for the coming year. Any one of these is a reason to compare your current plan against what is available for 2027.

Why does reviewing your Medicare plan each year matter?

Reviewing your plan each year matters because Medicare Advantage and Part D plans change their costs, drug lists, and provider networks annually. A plan that was the best fit when you enrolled can become a poor fit after the insurer updates its formulary or drops a pharmacy from the network. Your plan mails you an Annual Notice of Change every September that spells out these changes for the coming year. Reading it before October 15 puts you in a position to act during AEP instead of being locked in for another year.

How is Annual Enrollment different from Medicare Advantage Open Enrollment?

Annual Enrollment (October 15 to December 7) is open to everyone with Medicare and covers the widest range of changes. The Medicare Advantage Open Enrollment Period is a separate window that runs January 1 to March 31 and is only for people already enrolled in a Medicare Advantage plan. During that later window you can switch to a different Advantage plan or return to Original Medicare, but you cannot use it to join an Advantage plan from Original Medicare. For most people, the October to December AEP is the main opportunity to make a change.

What should Ohio seniors check before December 7?

Before December 7, work through this short checklist so your 2027 coverage matches your actual needs:

• Read your Annual Notice of Change. Compare next year's premium, deductible, and copays to what you pay now.
• Confirm your medications are covered. Check that each prescription is still on the plan's drug list and note which pricing tier it falls into.
• Verify your doctors and pharmacy are in network. Networks change, and an out-of-network provider can cost you significantly more.
• Compare total yearly cost, not just the premium. A low-premium plan with high copays can cost more overall than a higher-premium plan that covers your drugs well.
• Check dental, vision, and hearing extras if you rely on a Medicare Advantage plan for them, since those benefits are adjusted year to year.

Ohio residents can also use OSHIIP, the Ohio Senior Health Insurance Information Program run by the Ohio Department of Insurance, for free one-on-one Medicare counseling.
