Ohio is one of the most competitive Medicare Advantage markets in the Midwest. With 2.56 million Medicare-eligible residents and a penetration rate exceeding 56%, more than half of Ohio's Medicare population has already chosen a private Medicare Advantage plan over Original Medicare. The state's 212 plans for 2026 (down slightly from 217 in 2025) span HMOs, PPOs, and a large Special Needs Plan market tied to Ohio Medicaid, giving beneficiaries meaningful choices in nearly every county.
What makes Ohio distinct: a mix of national carriers (UnitedHealthcare, Humana, Aetna, Anthem) and strong regional plans (Medical Mutual of Ohio, SummaCare, CareSource, MediGold, PrimeTime Health Plan). Ohio has no 5-star plans for 2026, but several plans hold 4.5-star ratings. Urban counties like Cuyahoga (Cleveland) and Summit (Akron) have 70+ plan choices; rural Appalachian counties in southeastern Ohio have far fewer options. The state's average premium of $13.54 is slightly below the national average, and every county has at least one $0-premium plan.
This guide covers the 2026 Ohio Medicare Advantage market: plan counts, top carriers, plan types, how to enroll, and what to watch for when comparing plans. The Annual Election Period (AEP) for 2026 runs October 15 to December 7, with coverage effective January 1, 2027.

Plan Types in Ohio: HMO vs PPO vs SNP
Medicare Advantage plan-type breakdown in Ohio| Plan Type | Est. Plans | Avg Premium | Best For |
|---|
| HMO / HMO-POS | 105 | $10/mo | Lower premiums, comfortable using in-network Ohio providers |
| PPO | 68 | $20/mo | Flexibility to see out-of-network providers without a referral |
| Special Needs Plan (SNP) | 39 | $0/mo | Dual-eligible (Medicaid + Medicare), chronic conditions, institutional care |
| PFFS / MSA | ~0 | $0/mo | Rare in Ohio; check medicare.gov for current availability |
HMO and HMO-POS plans account for roughly half of Ohio's 212 plans. PPOs grew in 2025-2026 as more Ohioans seek network flexibility. SNPs represent a significant share due to Ohio's large dual-eligible population. Plan type counts are estimates based on CMS landscape data; exact counts vary by source.

What to Look For in a Medicare Advantage Plan in Ohio
Premium is not the only number that matters when picking a Medicare Advantage plan in Ohio. Here are six factors that carry the most weight in 2026:
- Provider network. Confirm your primary care doctor, specialists, and preferred hospital (Cleveland Clinic, OhioHealth, Ohio State Wexner Medical Center, Kettering Health, etc.) are in-network before you enroll. Ohio networks vary by carrier and county, and some plans use narrow networks tied to specific health systems.
- Prescription drug coverage (formulary). Most Ohio MA plans include Part D. Verify your specific medications are on the plan's formulary at the tier you can afford. The 2026 Part D out-of-pocket cap is $2,100 for all enrollees, a benefit created by the Inflation Reduction Act signed in 2022.
- Star Ratings. CMS rates every MA plan 1 to 5 stars based on about 40 quality measures covering chronic disease management, member experience, and prescription safety. Ohio's statewide weighted average is 3.9 stars. Plans rated 4 stars or higher receive quality bonus payments that fund richer benefits. The 4.5-star carriers in Ohio include Aetna, Humana, Medical Mutual of Ohio, SummaCare, MediGold, and PrimeTime Health Plan.
- Supplemental benefits (dental, vision, hearing, fitness). Most Ohio MA plans include some dental, vision, and hearing coverage that Original Medicare does not provide. Coverage depth varies widely: some plans offer only routine exams, while others cover hearing aids and comprehensive dental care. Compare the Evidence of Coverage for annual limits.
- Maximum out-of-pocket (MOOP). The 2026 federal in-network MOOP ceiling for Medicare Advantage is $9,250 (down from $9,350 in 2025). Many Ohio plans set theirs lower, between $4,500 and $7,500. Original Medicare has no out-of-pocket ceiling at all, which is a key reason people choose MA. Check each plan's specific MOOP before enrolling.
- Prior authorization requirements. Ohio MA plans can require prior authorization (PA) for surgeries, advanced imaging (MRI, CT scans), and specialist referrals. If you have a complex condition or anticipate significant care, ask about the plan's PA frequency and review CMS denial rate data published annually.
Key Medicare Dates in Ohio
Medicare enrollment has multiple windows. Missing the right window can mean waiting months for coverage or paying late enrollment penalties.
- Annual Election Period (AEP): October 15 - December 7, 2026 — The main shopping window. Switch between Original Medicare and Medicare Advantage, change MA plans, or add or change a standalone Part D plan. Coverage begins January 1, 2027.
- Medicare Advantage Open Enrollment Period (MA OEP): January 1 - March 31, 2026 — For current MA enrollees only. You can switch to a different MA plan or return to Original Medicare. One switch allowed during this period.
- Initial Enrollment Period (IEP): 7-month window around your 65th birthday — Starts 3 months before your 65th birthday month, includes the birthday month, and runs 3 months after. Enroll in Medicare Parts A and B, then choose Medicare Advantage or Original Medicare with a standalone Part D plan.
- Special Enrollment Periods (SEPs): Varies by qualifying event — Triggered by moving out of your plan's service area, losing employer coverage, gaining or losing Medicaid eligibility (dual-eligible SEP allows quarterly changes), or other qualifying events. Typically a 2-3 month window.
- 5-Star Special Enrollment Period: December 8, 2026 - November 30, 2027 — Ohio has no 5-star MA plans for 2026, so this window does not apply to Ohio beneficiaries this plan year. It allows enrollment any time into a 5-star plan, if one becomes available.
Notable Extras in Ohio Plans
Ohio Medicare Advantage has several state-specific features worth knowing about:
- OSHIIP: Free One-on-One Medicare Counseling: Ohio's Senior Health Insurance Information Program (OSHIIP) is the state's federally funded SHIP (State Health Insurance Assistance Program). Trained counselors help Ohio Medicare beneficiaries compare plans, understand rights, and navigate enrollment at no cost. Call 1-800-686-1578 or contact the Ohio Department of Insurance at insurance.ohio.gov. OSHIIP also runs Welcome to Medicare town halls across the state.
- CareSource MyCare Ohio: Integrated Dual-Eligible Plan: Ohio has an active financial alignment demonstration (MyCare Ohio) that integrates Medicaid and Medicare benefits for dual-eligible residents into a single managed care plan. CareSource MyCare Ohio is the primary D-SNP vehicle in many counties, offering $0 premiums, $0 copays, and coordinated care managers. Dual-eligible beneficiaries in Ohio can also change plans once per quarter (Q1, Q2, Q3), plus during AEP.
- Regional High-Quality Plans: Ohio has a notable cluster of regional Medicare Advantage plans with strong local reputations and above-average Star Ratings. SummaCare (Summa Health, Akron, 4.5 stars, 33 northeast Ohio counties), MediGold (OhioHealth, Columbus, 4.5 stars), and PrimeTime Health Plan (Akron/Canton, 4.5 stars) all consistently outperform national carrier averages in Ohio. These plans tend to have smaller but tightly managed provider networks.
How to enroll in Ohio Medicare Advantage
Enrollment in Medicare Advantage is handled federally through CMS, but Ohio-specific resources like OSHIIP can walk you through every step at no cost. You can enroll online, by phone, or through a licensed insurance agent. Confirm your doctors accept the plan before you finalize enrollment.
You must already be enrolled in Medicare Parts A and B before you can join a Medicare Advantage plan. If you are turning 65, enroll in Parts A and B first during your 7-month Initial Enrollment Period, then choose your MA plan.
- Step 1: Confirm you are enrolled in Medicare Parts A and B (call Social Security at 1-800-772-1213 or check ssa.gov if unsure).
- Step 2: Use the CMS Medicare Plan Finder at medicare.gov/plan-compare to compare Ohio MA plans by ZIP code. Filter by Star Rating, premium, and whether your doctors and drugs are covered.
- Step 3: Contact OSHIIP (1-800-686-1578) for free personalized counseling. OSHIIP counselors can compare plans side-by-side with you and explain your rights before you commit.
- Step 4: Enroll during a valid enrollment window (AEP: October 15 to December 7, or your IEP, or an applicable SEP). Submit your enrollment online at medicare.gov, call 1-800-MEDICARE (1-800-633-4227), or enroll directly through the plan's website or a licensed broker.
- Step 5: Confirm your enrollment by reviewing the plan's welcome packet and ID card, which arrives within 10 business days of your enrollment being processed. Verify your primary care doctor and any preferred specialists are listed in the plan's current provider directory.
How to enroll in Ohio Medicare Advantage detail| Document | Why You Need It |

$0 premium Medicare Advantage plans in Ohio (2026)
Every Medicare-eligible Ohioan has access to at least one $0-premium Medicare Advantage plan in 2026. In major metro counties, the selection is substantial. A $0-premium plan means you pay no monthly plan premium beyond your standard Part B premium ($202.90 in 2026), but you still have copays, coinsurance, and deductibles when you use care. Compare total annual cost (premium + cost-sharing + drugs), not just the monthly premium.
$0 premium Medicare Advantage plans in Ohio (2026) detail| County | Metro Area | $0 Premium Plans Available (Est.) | Total Plans 2026 |
|---|
| Cuyahoga | Cleveland | 36+ | 72 |
| Summit | Akron | 46+ | 70 |
| Hamilton | Cincinnati | 30+ | 64 |
| Franklin | Columbus | 37+ | 61 |
| Montgomery | Dayton | 25+ | ~50 |
Estimates based on Connie Health and Medicare.org county-level data for 2026. Exact counts vary by ZIP code within a county. Some $0-premium plans charge cost-sharing that can exceed the premium savings if you use significant care,compare total annual out-of-pocket limits, not just monthly premium.

Medicare Advantage vs Original Medicare in Ohio
Original Medicare (Parts A and B) plus a Medigap supplement and a standalone Part D plan gives you nationwide provider access and minimal prior authorization, but the monthly cost in Ohio typically runs $180 to $350 for Medigap + Part D combined. Medicare Advantage bundles all coverage into one plan at an average of $13.54 per month statewide, but comes with a defined provider network and prior authorization requirements for many services.
If you travel frequently between Ohio and other states, or you need access to out-of-state specialists (such as specialists at institutions outside Ohio's borders), Original Medicare plus Medigap is usually a better fit. If you live in Ohio year-round and want lower monthly costs plus dental, vision, and hearing benefits, Medicare Advantage typically offers better total value. The 2026 Part A inpatient hospital deductible is $1,736 per benefit period, and Part B standard premium is $202.90 per month,both costs you'll owe under Original Medicare regardless of how much care you use.
Ohio Medicaid, dual eligibility, and D-SNPs
Ohio residents who qualify for both Ohio Medicaid and Medicare are dual eligible. Dual-eligible beneficiaries can enroll in a Dual Special Needs Plan (D-SNP), which coordinates both programs and typically offers $0 premiums, $0 copays for primary and preventive care, and reduced or eliminated drug costs. Ohio's primary D-SNP vehicle is CareSource MyCare Ohio, available in most counties.
Dual-eligible Ohio beneficiaries also have expanded enrollment rights: you can change MA plans once per calendar quarter in Q1, Q2, and Q3, plus during AEP. If your Medicaid status changes, that also triggers a Special Enrollment Period. UnitedHealthcare and Humana also offer D-SNP plans in Ohio for 2026. Check whether you qualify for Extra Help with Part D costs.
