Rehab Cost in Montana: 2026 Treatment Cost Guide
Montana recorded 217 drug overdose deaths in 2022, a rate of approximately 19 per 100,000 residents according to CDC WONDER. While Montana’s overall rate remains below the national average, fentanyl-involved deaths rose sharply between 2019 and 2022, and methamphetamine continues to dominate treatment admissions across the state. Montana’s challenge is less about absolute numbers and more about geography: the fourth-largest state by land area serves just over 1.1 million people, and residential treatment capacity is concentrated in a handful of cities separated by hundreds of miles of highway.
Montana’s treatment landscape was reshaped by the 2015 Health and Economic Livelihood Partnership (HELP) Act, which expanded Medicaid to adults earning up to 138% of the federal poverty level. Voters made expansion permanent through the 2019 legislative renewal. Approximately 80,000 Montanans gained coverage, closing the coverage gap that had previously left many working-poor adults without any affordable path to treatment. This guide breaks down what rehab actually costs in Montana, what insurance and Medicaid cover, and how to find help even in the most remote parts of the state.

Montana treatment costs run slightly above the Mountain West average because of limited residential capacity and the travel burden many patients face. Daily inpatient rates typically range from $450 to $1,250. Rural travel, lodging for family visits, and lost wages during residential stays can add thousands of dollars beyond the published program fee.
Why Montana Rehab Costs Are Higher Than Neighbors
Several Montana-specific factors influence cost:
Limited Residential Supply: Montana has roughly 16 residential/inpatient facilities statewide. Limited supply against consistent demand keeps private-pay rates from falling.
Geographic Distance: Montana is 147,000 square miles — larger than Japan. Facilities must serve enormous catchment areas, and many residents travel 150-300 miles to access care.
Rural Labor Costs: Attracting and retaining licensed addiction counselors, psychiatrists, and nurses in rural Montana requires premium compensation, inflating program operating costs.
Tribal Service Demand: Seven reservations and a significant urban Native population create additional demand for culturally-specific treatment. While Indian Health Service provides no-cost care to eligible members, non-tribal residents often face waitlists at state-contracted facilities.
Regional Cost Variation:
- Billings (Yellowstone County): $14,000-$32,000 (state’s largest treatment market)
- Missoula: $14,000-$34,000 (western hub)
- Great Falls: $12,000-$28,000 (central hub)
- Bozeman: $16,000-$40,000 (higher cost of living)
- Helena: $13,000-$28,000 (state capital)
- Eastern Montana: often requires travel to Billings or out-of-state
Montana’s Treatment Landscape
Montana has approximately 98 licensed treatment facilities statewide, including 16 offering residential or inpatient care, according to the SAMHSA Treatment Locator. The Montana Department of Public Health and Human Services Addictive and Mental Disorders Division (AMDD) licenses providers and administers state and federal treatment funding.
Distribution of Treatment Facilities in Montana
Treatment facilities follow Montana’s population centers and I-90/I-15 corridors:
- Yellowstone County (Billings): 22 facilities (state’s treatment hub)
- Missoula County: 16 facilities
- Cascade County (Great Falls): 11 facilities
- Gallatin County (Bozeman): 10 facilities
- Lewis and Clark County (Helena): 9 facilities
- Flathead County (Kalispell): 8 facilities
- Silver Bow County (Butte): 6 facilities
Eastern Montana counties — Dawson, McCone, Garfield, Petroleum — often have no licensed SUD providers at all. Residents depend on telehealth services, long-distance travel, or cross-state referrals to North Dakota or Wyoming.
Key Montana Treatment Regulations
HELP Act Medicaid Expansion: Montana expanded Medicaid in 2016 through the HELP Act and made expansion permanent in 2019. The program covers approximately 80,000 previously uninsured adults earning up to 138% of the federal poverty level. Montana’s uninsured rate dropped from more than 14% pre-expansion to 8.3% in 2023.
AMDD Licensing and Funding: The Addictive and Mental Disorders Division licenses all Montana SUD treatment providers and administers the federal Substance Abuse Prevention and Treatment (SAPT) Block Grant, State Opioid Response (SOR) funds, and state general fund appropriations.
Indian Health Service Partnership: Montana’s seven reservations are served by IHS facilities that provide SUD treatment to eligible tribal members at no cost. The Montana-Wyoming Tribal Leaders Council and state AMDD coordinate on cross-jurisdictional treatment referrals.
MAT Expansion: Montana has significantly expanded access to medication-assisted treatment through the State Opioid Response grant, funding buprenorphine waivers for primary care providers and mobile methadone initiatives.
Insurance Coverage in Montana
Montana’s uninsured rate of 8.3% (U.S. Census Bureau, 2023 ACS) is near the national average, down dramatically from pre-expansion levels. About 66,000 Montanans enrolled in ACA marketplace plans for 2025 coverage.

AMDD State-Funded Treatment: The Addictive and Mental Disorders Division funds treatment through contracted regional providers. Uninsured Montanans can access no-cost or sliding-scale treatment through regional behavioral health authorities.
Indian Health Service / Urban Indian Health: Tribal members and descendants can access SUD treatment through IHS facilities and urban Indian health centers at no cost.

Detox Costs in Montana
Alcohol Detox: $200-$475 per day ($1,400-$6,650 total for 7-14 days). Alcohol withdrawal can be life-threatening and requires 24/7 medical monitoring.
Opioid Detox: $200-$425 per day ($1,400-$4,250 total for 7-10 days). Most Montana programs use buprenorphine-assisted withdrawal.
Benzodiazepine Detox: $225-$500 per day ($3,150-$7,000 for 14 days). Requires slow tapering due to seizure risk.
Methamphetamine Detox: $175-$375 per day ($875-$2,625 for 5-7 days). Methamphetamine is Montana’s dominant treatment admission driver, and most Montana detox programs have significant experience with stimulant withdrawal management.
Fentanyl Detox: $200-$450 per day ($2,000-$4,500 for 10+ days). Given fentanyl’s rising share of Montana overdose deaths, most programs now use extended stabilization and micro-dosing buprenorphine induction.

Final Thoughts: Getting Help in Montana
Montana’s HELP Act Medicaid expansion fundamentally changed treatment access for tens of thousands of working-poor residents who previously had no affordable coverage option. Combined with the Indian Health Service, urban Indian health centers, and a statewide AMDD-contracted provider network, Montana now offers more pathways to treatment than at any point in state history.
- Call 988 for immediate crisis support
- Check Montana Medicaid (HELP Plan) eligibility — expansion covers adults earning up to 138% FPL
- Explore ACA marketplace plans at HealthCare.gov — subsidized coverage starting as low as $0-$75/month
- Contact AMDD or your regional provider — no-cost state-funded treatment for uninsured residents
- For tribal members, contact IHS or an urban Indian health center — culturally-specific treatment at no cost
The biggest barrier in Montana is not cost — it’s distance. Treatment works, and Montana’s growing telehealth MAT network, mobile methadone, and regional provider system have made that distance more manageable than ever.
