Healthcare in District of Columbia

The District of Columbia, while not a state, has one of the most concentrated collections of world-class medical institutions in the United States. Washington, D.C. is home to MedStar Washington Hospital Center — the largest hospital in the District and a Level I Trauma Center — George Washington University Hospital (GWU Hospital), Georgetown University Hospital, Howard University Hospital, and Children's National Hospital, consistently ranked among the top children's hospitals in the nation.

The District also houses major federal health agencies, including the National Institutes of Health (NIH) Clinical Center in nearby Bethesda, Maryland — the world's largest hospital dedicated to clinical research — and the Walter Reed National Military Medical Center in Bethesda, the flagship military hospital in the United States.

D.C. has one of the most generous Medicaid programs in the country, covering adults earning up to 215% of the federal poverty level. The DC Department of Health Care Finance (DHCF) (dhcf.dc.gov) administers Medicaid, while the DC Health (dchealth.dc.gov) oversees public health programs and healthcare licensing. Despite its wealth of medical resources, D.C. has significant health disparities between its wealthier northwest neighborhoods and lower-income areas in the east and southeast.
