Graphic of the week: Medicaid expansion and Ohio's uninsured rate

By Health Policy Institute of Ohio / June 13, 2025

The Health Policy Institute of Ohio has completed a comprehensive, data-driven study to describe how the expansion of Medicaid in Ohio in 2014 impacted coverage, access and affordability and to estimate the future impacts of discontinuing coverage.
 
HPIO’s 2025 Ohio Medicaid Expansion Study includes a series of five reports looking at various facets of the issue, including:

• Access to mental health and substance use disorder treatment

• Parents, caregivers and their children

• The state budget

• Health insurance coverage and cost

• Jobs and the economy

The brief on health insurance coverage and cost, which was released last week, found that Medicaid expansion cut Ohio’s uninsured rate in half from 2012 to 2023. If expansion was eliminated, the uninsured rate could increase by 80% in 2026. Certain groups of Ohioans, including Ohioans with a high school education or less, would be more likely to become uninsured, as illustrated above.

HPIO’s recently released 2025 Ohio Medicaid Basics and Policy Considerations: The Future of Group VIII (expansion) Medicaid Coverage in Ohio briefs contain more general information on the Medicaid program overall and considerations about Medicaid expansion coverage as policymakers consider the program's future.
