Medigap vs. Medicare Advantage in Ohio

In Ohio, Original Medicare with a Medigap policy usually costs more each month but has no network and few bills when you get care; Medicare Advantage usually costs less up front, uses a network and charges copays as you go. Ohio has no Medigap birthday rule, so moving from Medicare Advantage back to Medigap later can mean health questions. The choice you make at 65 matters most.

How does each option work?

Original Medicare with Medigap: Medicare pays first for hospital and medical care, and your Medigap policy pays some or all of what's left, such as deductibles and the 20% Part B coinsurance. You add a standalone Part D plan for drugs. See Medigap in Ohio.

Medicare Advantage: a private plan approved by Medicare replaces Original Medicare for your Part A and Part B care. Most plans include Part D, use a provider network, and charge copays or coinsurance as you use care, up to a yearly limit. See Medicare Advantage in Ohio.

You need Part A and Part B either way, and you keep paying your Part B premium either way. In Ohio, 1,490,804 of 2,635,104 people with Medicare were in Medicare Advantage or another Medicare health plan in July 2026, per CMS.

How do the costs compare?

Cost	Original Medicare + Medigap + Part D	Medicare Advantage
Monthly premium	Part B, plus the Medigap premium, plus the Part D premium.	Part B, plus the plan's premium if it has one.
Bills when you get care	Depends on the plan letter. Plan G leaves you the Part B deductible; Plans K, L and N leave more cost sharing.	Copays or coinsurance for most services, set by the plan.
Yearly limit on medical costs	None in Original Medicare alone. Plan K's limit is $8,360 and Plan L's $4,180 in 2027; with Plan G, very little is left to pay.	Required: up to $9,850 in network in 2027 (a PPO's combined limit can be up to $14,800).
Drug costs	Through a Part D plan, capped at $2,400 in 2027.	Usually included, with the same $2,400 cap.
How premiums change	Medigap premiums usually rise over time. Ohio doesn't require one pricing method, so ask whether a policy is priced by issue age or attained age.	Premiums and benefits can change every January 1; your Annual Notice of Change shows what's new.

Ohio law also bars health care practitioners from balance billing people with Medicare (ORC 4769.02), so Ohio providers shouldn't bill you above the Medicare-approved amount under Original Medicare.

Medicare Advantage plans may offer extra benefits such as dental, vision, hearing or fitness. Extra benefits vary by plan and county, may have limits and costs, and not every plan offers them. Check a plan's Summary of Benefits or Evidence of Coverage.

Networks, Florida winters and rural Ohio

Question	Original Medicare + Medigap	Medicare Advantage
Which doctors and hospitals?	Any provider in the U.S. who accepts Medicare.	The plan's network. HMOs generally cover out-of-network care only for emergencies and urgent care; PPOs cover it at a higher cost.
Referrals and prior approval	No referrals. Medicare's rules decide what's covered.	Many plans need referrals or prior authorization for some services.
Winters in Florida or elsewhere	Works the same in every state.	Emergencies and urgent care are covered; routine care away usually isn't in an HMO. More than 6 months in a row away ends your enrollment unless the plan has a visitor program.
Travel outside the U.S.	Plans C, D, F, G, M and N pay 80% of emergency care for the first 60 days of a trip, after a $250 deductible, up to a $50,000 lifetime limit.	Generally not covered; check the plan's Evidence of Coverage.
Rural and Appalachian Ohio	Works with any hospital or clinic that accepts Medicare, including across the river in West Virginia or Kentucky.	Depends on the county. For 2027, Summit County has 68 plans open to everyone and Scioto County 22; check the network near you.

Switching later: why Ohio's rules matter

Ohio has no Medigap birthday, anniversary or yearly switching rule (ORC 3923.33 to 3923.339; OAC 3901-8-08). House Bill 24 would add one; as of November 2026 it is still in the House Insurance Committee and dies if it isn't passed by December 31, 2026. That makes the direction you move important.

Change	Health questions?	Rule
Buy Medigap in your first 6 months when you're both 65 and in Part B	No	Medigap open enrollment, OAC 3901-8-08(N)
Switch Medigap policies later	Usually yes	No Ohio birthday rule
Leave Medicare Advantage for Medigap	Usually yes	No health questions only with a guaranteed-issue right, OAC 3901-8-08(O)
Leave Medicare Advantage within 12 months of joining at 65 (trial right)	No	Guaranteed issue for any Medigap policy sold in Ohio
Your Medicare Advantage plan ends or leaves your county	No, for Plans A, B, D, G, K or L (C or F if eligible before 2020)	Guaranteed issue; apply up to 63 days after coverage ends
Switch Medicare Advantage plans	No	October 15 to December 7, and January 1 to March 31

In short: in Ohio it's easier to start with Medigap and move to Medicare Advantage later than the other way around. If you're under 65 with Medicare because of a disability, Ohio doesn't require companies to sell you Medigap; your guaranteed chance comes at 65, or in a federal guaranteed-issue situation.

Other Ohio factors to weigh

Ohio Medicaid: with full Medicaid you usually don't need Medigap; MyCare Ohio's plans can cover both Medicare and Medicaid. See MyCare Ohio and Medicare Savings Programs in Ohio.
Public retirees: OPERS, OP&F and HPRS retirees choose individual plans through their system's marketplace; STRS Ohio and SERS offer group Medicare Advantage plans, and joining another plan can end that coverage. See Ohio public retirement systems and Medicare.
Veterans: VA care and TRICARE For Life work alongside Medicare. See veterans, TRICARE and military retirees in Ohio.
Plans ending in 2027: if your Medicare Advantage plan is ending, this is a rare chance to buy Medigap without health questions. See Ohio plans ending in 2027.

How to decide

List your doctors, hospitals and drugs. Include specialists in Cleveland, Columbus or Cincinnati and any provider across a state line.
Check what's sold in your county. Look up your county on our counties page and check each plan's network for your providers.
Compare a typical year and a bad year. Add premiums and expected copays, then compare with the plan's out-of-pocket limit or your Medigap plan's coverage.
Think about winters away. If you spend months outside Ohio, weigh how each option handles care there.
Mind your timing. Your Medigap open enrollment period at 65 is the one time any company must sell you any policy it offers. Ohio gives you 30 days after delivery to return a new Medigap policy for a refund.

To compare Medigap policies and Medicare Advantage plans from the companies they work with, you can request a call from a licensed insurance agent, or see plans for your ZIP code. Complaints about an agent or company go to Ohio Department of Insurance Consumer Services at 1-800-686-1526.

Frequently asked questions

Is Medigap or Medicare Advantage better in Ohio?

Neither is better for everyone. Medigap with Original Medicare suits people who want any provider in the U.S. who accepts Medicare, spend winters away, or want predictable bills. Medicare Advantage suits people comfortable with a local network who want drug coverage and possible extra benefits in one plan.

Can I have Medicare Advantage and Medigap at the same time?

No. A Medigap policy doesn't pay anything while you're in Medicare Advantage, and it's illegal for a company to sell you one then unless you're switching back to Original Medicare. If you already have Medigap and join Medicare Advantage, you may want to keep it during your 12-month trial period.

What is the Medicare Advantage trial right?

If you join a Medicare Advantage plan when you're first eligible at 65 and leave within 12 months, you can buy any Medigap policy sold in Ohio without health questions. If you dropped a Medigap policy to try Medicare Advantage for the first time, you can get that policy back within 12 months if the company still sells it.

If I choose Medicare Advantage, can I switch to Medigap later in Ohio?

You can return to Original Medicare during open enrollment or the January to March window, but outside a guaranteed-issue situation a Medigap company can ask health questions and turn you down. A bill (HB 24) to add a yearly switching right has been proposed; it is not law.

Do I need a separate drug plan with Medigap?

Yes. Medigap policies don't cover prescriptions, so most people with Medigap also join a standalone Part D plan. CMS lists 9 standalone Part D plans in Ohio for 2027. Most Medicare Advantage plans include drug coverage.
