Healthcare in Texas

Texas has the second-largest healthcare system in the United States, serving a population of nearly 30 million residents across a vast and geographically diverse state. The Texas Medical Center (TMC) in Houston is the world's largest medical complex, encompassing over 60 institutions including MD Anderson Cancer Center (consistently ranked #1 in the nation for cancer care), Houston Methodist Hospital, Memorial Hermann Health System, Baylor St. Luke's Medical Center, and Texas Children's Hospital (one of the top pediatric hospitals in the country).

Dallas-Fort Worth is served by major systems including UT Southwestern Medical Center, Baylor Scott & White Health (the largest not-for-profit health system in Texas), Texas Health Resources, and Parkland Memorial Hospital. San Antonio has the University Health System and CHRISTUS Health, while Austin is home to Ascension Seton and St. David's HealthCare.

Texas has not expanded Medicaid under the ACA and has one of the highest uninsured rates in the nation. The state Medicaid program, administered by the Texas Health and Human Services Commission (HHSC) (hhs.texas.gov), covers low-income children, pregnant women, and people with disabilities. The Texas Medical Board (tmb.state.tx.us) licenses and regulates physicians statewide.
