Healthcare in Oklahoma

Oklahoma's healthcare system serves approximately 4 million residents, with Oklahoma City and Tulsa serving as the primary healthcare hubs. OU Health (University of Oklahoma Health Sciences Center) in Oklahoma City is the state's flagship academic medical center, operating OU Medical Center — a Level I Trauma Center — and Children's Hospital at OU Medicine. Integris Health is the state's largest not-for-profit health system, operating hospitals across Oklahoma. In Tulsa, Ascension St. John Medical Center and Saint Francis Health System are the dominant providers.

Oklahoma expanded Medicaid in 2021 through a voter-approved ballot initiative. The program, called SoonerCare, now covers adults earning up to 138% of the federal poverty level. The Oklahoma Health Care Authority (OHCA) (okhca.org) administers SoonerCare. Oklahoma has significant rural healthcare challenges, with many counties having few primary care physicians and several rural hospitals having closed in recent years.

The Oklahoma State Board of Medical Licensure and Supervision (okmedicalboard.org) licenses allopathic physicians, while the Oklahoma State Board of Osteopathic Examiners licenses DOs. Both boards provide online verification.
