Healthcare in Maryland

Maryland is home to one of the most distinguished healthcare systems in the world, anchored by Johns Hopkins Medicine in Baltimore — consistently ranked as one of the top hospitals in the United States and globally renowned for medical research, education, and clinical care. University of Maryland Medical System (UMMS) is the state's largest health system, operating the University of Maryland Medical Center (a Level I Trauma Center and academic medical center) along with hospitals throughout the state. MedStar Health and Luminis Health are other major systems serving the Baltimore-Washington corridor.

Maryland's proximity to Washington, D.C. means that many residents also access care at major medical centers in Northern Virginia and the District. The state has a highly educated and relatively affluent population, contributing to better-than-average health outcomes in many metrics. However, Baltimore City faces significant health disparities, with elevated rates of chronic disease, violence-related trauma, and substance use disorders in many neighborhoods.

Maryland expanded Medicaid in 2014, and the program covers approximately 1.6 million residents. The state operates Maryland Health Connection (marylandhealthconnection.gov), its own ACA marketplace. The Maryland Board of Physicians (mbp.state.md.us) licenses physicians and provides online verification.
