Billings provides the main medical services for a four-state area, with state-of-the-art equipment and highly skilled personnel. The community is served by nearly 500 physicians and dentists. Most of the health care facilities are concentrated in a 114-acre medical corridor that encompasses both of the city's major hospitals and 20 other health-related facilities.
Billings Deaconess Hospital, part of the Deaconess-Billings Clinic Health System, is a 272-bed Level II trauma center with general care and specialized services that include a cardiac care center, cancer services, an intensive care unit, the Kidney Center, a psychiatric center, pulmonary services, Women's Resource Center, occupational health and wellness, orthopedics and sports medicine, and a Research Institute. In 2004 ground was broken on a $27 million expansion to the hospital's Regional Emergency and Trauma Center.
A 302-bed Level II trauma center, the St. Vincent Hospital and Health Center is operated by the Sisters of Charity of Leavenworth and provides comprehensive inpatient and out-patient services, special services for women and seniors, and expertise in cardiology, orthopedics, general internal medicine, pediatrics, emergency and trauma, neurosciences, rehabilitation, neonatology, and oncology.
