Montana Health Insurance 2026

Montana is a high-premium state due to its small, dispersed population and frontier geography. The ACA marketplace offers only 15–30 plans statewide, with BCBS of Montana, PacificSource, and the Mountain Health CO-OP as the primary carriers. Silver premiums for a 40-year-old average $565–$595/month before subsidies. Montana implemented a Section 1332 reinsurance waiver, which has moderated what would otherwise be even higher premiums. Network adequacy is a significant challenge in rural counties, where accessing specialist care may require long drives or air travel. Montana uses Healthcare.gov for marketplace enrollment.

Montana expanded Medicaid in 2016 through the HELP Act, which was extended in 2019 and made permanent in 2021. The expansion has covered approximately 100,000 Montanans. Montana's rural and tribal communities have benefited significantly from the expansion, as access to coverage had been especially sparse. The state has no state-based exchange. Montana's large Native American population — served by Indian Health Service and Medicaid — benefits from the expanded eligibility, though access to IHS facilities remains the primary care source for many.
