The four parts of Medicare

Original Medicare is two parts, A and B. Together with Part D for prescriptions and Part C (Medicare Advantage) as a private alternative, they cover the full picture.

Key Medicare dates for Ohioans

Most Medicare changes happen during a few specific windows each year. Missing them can mean late penalties or being stuck with the wrong plan until next October.

Initial Enrollment

Turning 65

7-month window

Starts 3 months before your 65th birthday month, includes that month, and runs 3 months after.

Annual Enrollment

AEP for everyone

Oct 15 – Dec 7

Switch Medicare Advantage plans, change Part D, or move between Original Medicare and Advantage. Changes take effect Jan 1.

MA Open Enrollment

One more chance

Jan 1 – Mar 31

If you're already in a Medicare Advantage plan, you can switch to another MA plan or back to Original Medicare + Part D once.

General Enrollment

If you missed IEP

Jan 1 – Mar 31

For people who didn't enroll in Part B when first eligible. Coverage starts the month after enrollment. Late penalties may apply.

Ohio in Context

Why your Medicare choices look different in Ohio

01 — Market Size

The 6th-largest Medicare state

More than 2.5 million Ohioans are enrolled in Medicare, with Medicare Advantage penetration among the highest in the country. That competition tends to mean richer benefits and more $0-premium plans in metro Ohio than you'll see in smaller states.

02 — Deep Carrier Market

National and regional plans

Both national insurers and Ohio-rooted regional plans compete here, which often means richer benefits and more $0-premium options than smaller-market states see. Star Ratings vary by county — the same carrier can be 4.5 stars in one ZIP and 3.5 stars in the next.

03 — 2026 Shake-Up

Plans are changing in dozens of counties

Several Ohio Medicare Advantage carriers are non-renewing plans for 2026, hospital-system network contracts are being renegotiated, and some supplemental benefits are being restricted. If you're already enrolled, read your Annual Notice of Change carefully.

04 — Dual Eligibles

Next Generation MyCare Ohio

For people with both Medicare and Medicaid, the Ohio Department of Medicaid is rolling out Next Generation MyCare in 2026 across 29 counties — including the Columbus, Cleveland, Cincinnati, and Dayton metros. Coverage is delivered through several contracted managed-care organizations.
