Ohio Medicare Plans: Medigap, Advantage, Part D, and Dual-Eligible

Medicare in Ohio comes in four flavors, and which one is right for you depends on your health, budget, doctors, and prescription list. Medigap (Supplement) pairs with Original Medicare for the most provider freedom — Ohio has 12 Medigap plans on the 2026 market. Medicare Advantage bundles A, B, often D, and extras into one plan with network restrictions — 59 MA plans in Ohio for 2026. Part D drug plans pair with Original Medicare or are built into MA — 19 stand-alone Part D plans in Ohio for 2026. Dual-eligible integrated plans (Next Generation MyCare Ohio) serve Ohioans with both Medicare and Medicaid.

Pick the plan type that fits

The plan you pick at 65 isn't permanent, but it sets your defaults for years to come. The four main types each have a different cost structure, network model, and Ohio-specific quirks worth understanding before you enroll.

How to choose

Start with what's non-negotiable for you. The three questions that decide most plan picks:

  1. Are there specific doctors or hospitals you must see? If yes — and they're at a major academic medical center like Cleveland Clinic, OSU Wexner, or UC Health — Medigap with Original Medicare gives you the broadest access (any provider that takes Medicare). Medicare Advantage networks vary, and sometimes the largest hospital systems are in-network only with certain MA carriers.
  2. How predictable are your medical costs? If you take a lot of prescriptions, have chronic conditions, or want to know exactly what each visit will cost — Medigap's higher premium for low cost-sharing usually saves money over time. If you're healthy, rarely visit doctors, and want low premiums — Medicare Advantage's $0 premiums and bundled extras (dental, vision, OTC) can be a better deal.
  3. Do you have retiree coverage from an Ohio pension or PSHB? If yes, the trade-off changes — your pension's group plan may be better than anything individual, or it may not be. See Ohio public pensions and Medicare for the pension-by-pension breakdown.

Common pitfalls

  • Don't enroll in both Medigap and Medicare Advantage. It's illegal for an agent to sell you Medigap if you're on MA, and vice versa — the two structures conflict.
  • Don't enroll in two Part D plans. If your MA plan already includes Part D, a stand-alone PDP cancels the MA plan. If your STRS Ohio or SERS group plan has built-in Rx, a separate PDP cancels the group plan.
  • Don't drop Medigap to try MA without understanding the switch-back risk. Ohio has no birthday rule. Once you leave Medigap, getting back in usually requires medical underwriting — and pre-existing conditions can mean denial or higher rates.
  • Don't skip Part B because "I have something else." Most "something else" is secondary to Medicare. Skipping Part B at 65 means a lifetime late-enrollment penalty unless you have qualifying employer coverage from an employer with 20+ employees.
