Healthcare in Ohio

Ohio has one of the most distinguished healthcare systems in the United States, home to world-renowned medical institutions and a strong network of regional hospitals. Cleveland Clinic is consistently ranked among the top hospitals in the nation and is globally recognized for cardiac care — its Heart and Vascular Institute has been ranked #1 in the nation for cardiology and cardiac surgery for over 25 consecutive years. University Hospitals Cleveland Medical Center and MetroHealth are other major academic medical centers in Cleveland. In Columbus, OhioHealth and Ohio State University Wexner Medical Center are the dominant health systems. Cincinnati Children's Hospital Medical Center is consistently ranked among the top children's hospitals in the nation.

Ohio expanded Medicaid in 2014, and the program covers approximately 3.5 million residents. The Ohio Department of Medicaid (ODM) (medicaid.ohio.gov) administers the program. Ohio has been severely impacted by the opioid epidemic, and the state has invested heavily in addiction treatment, harm reduction, and recovery support services. The State Medical Board of Ohio (med.ohio.gov) licenses physicians and provides online verification.
