Healthcare in Montana

Montana is the fourth-largest state by area but one of the least densely populated, presenting significant healthcare delivery challenges. With approximately 1.1 million residents spread across a vast landscape, many Montanans live far from hospitals and specialist services. Billings Clinic and St. Vincent Healthcare (part of SCL Health) in Billings are the state's largest hospitals and primary referral centers. Benefis Health System in Great Falls, Providence St. Patrick Hospital in Missoula, and Bozeman Health are other major regional providers.

Montana expanded Medicaid in 2016 through a bipartisan legislative effort, extending coverage to approximately 100,000 low-income adults. The program, called Montana Medicaid, is administered by the Montana Department of Public Health and Human Services (DPHHS) (dphhs.mt.gov). The state uses a federally facilitated marketplace for ACA plans.

Montana has a significant Native American population, and the Indian Health Service (IHS) operates facilities on several reservations. Behavioral health, particularly substance use disorder and suicide prevention, is a major public health priority. The Montana Board of Medical Examiners (boards.bsd.dli.mt.gov/med) licenses physicians and provides online verification.
