About Rimrock

Rimrock, located at 1231 North 29th Street in Billings, Montana, is the largest drug and alcohol addiction treatment center in the region. Serving adults across Yellowstone County and throughout Montana — including Bozeman — Rimrock specializes in substance use treatment alongside co-occurring disorders such as trauma, PTSD, mental illness, and dual diagnosis conditions. Its scale and regional reach set it apart from smaller facilities competing for the same patients in the Mountain West.

The facility offers a full continuum of care anchored by medical detox, making it a resource for individuals who require supervised withdrawal management before stepping down to less intensive services. Beyond detox, Rimrock provides residential treatment for those needing immersive, structured programming, as well as an outpatient program and an Intensive Outpatient Program (IOP) for individuals who can manage treatment while living in the community. This range of levels of care means patients can move through treatment at a clinically appropriate pace without transferring to an entirely different facility.

Rimrock’s clinical model incorporates Medication Assisted Treatment (MAT), Cognitive Behavioral Therapy (CBT), family therapy, Parent Child Interaction Therapy, and anger assessment and management. The facility also addresses alcohol addiction and gambling addiction as confirmed conditions treated, and aftercare support includes counseling services, mental health evaluations, and clinical supervision. The Garden of Hope and Recovery Lodges are on-site features that distinguish the physical campus, and CARF accreditation reflects an external quality standard the facility has met.

Rimrock serves a notably broad population: veterans, pregnant women, young adults ages 18–25, seniors, men, women, adults with HIV/AIDS support needs, individuals who are deaf or hard of hearing, court-ordered participants, and adults generally. Payment options include Medicaid, private insurance, TRICARE, state insurance, and self-pay, making the facility accessible to a wide range of financial situations. For anyone in Montana weighing where to begin medically supervised detox and a full course of addiction treatment, Rimrock’s regional standing and population breadth are practical differentiators.

Medical Detox and Withdrawal Management at Rimrock

For individuals facing substance use disorders who need medically supervised detox as a first step, Rimrock provides withdrawal management as the entry point to its continuum of care. Medical detox at Rimrock is followed by clearly defined pathways into residential treatment or outpatient programming, so the transition from acute withdrawal stabilization to longer-term treatment happens within the same organization.

Rimrock also incorporates Medication Assisted Treatment (MAT) into its clinical services — a protocol that uses FDA-approved medications alongside behavioral therapies to address the physiological dimension of addiction. For patients and families researching detox programs in Montana, MAT availability is a meaningful clinical differentiator when comparing facilities in the Billings and Bozeman areas.

Levels of Care: From Inpatient Detox to Intensive Outpatient

Rimrock's structure allows patients to enter at the appropriate level of clinical intensity. Medical detox serves those who cannot safely withdraw without supervision. Residential treatment provides immersive programming for individuals who need a structured environment beyond the acute detox phase. For those who have stabilized or whose circumstances allow them to live outside a facility, both a standard outpatient program and an Intensive Outpatient Program (IOP) are available.

This continuum matters practically: patients treated at Rimrock do not have to navigate referrals to unaffiliated programs as their clinical needs change. The facility also treats co-occurring disorders — including trauma, PTSD, mental illness, and dual diagnosis conditions — alongside substance use, which reflects the clinical reality that these conditions frequently present together in patients seeking detox and addiction treatment.

Who Rimrock Serves Across Montana

Rimrock's confirmed service area covers Billings, Bozeman, and greater Montana — a geographic footprint that reflects its status as the region's largest treatment center. The facility serves a wide range of adult populations, including veterans (with TRICARE accepted as a payment method), pregnant women, young adults ages 18–25, seniors, and individuals who are deaf or hard of hearing. Court-ordered participants and those with HIV/AIDS support needs are also among the populations the facility is equipped to treat.

Beyond clinical populations, Rimrock's payment options extend access across income levels. Medicaid, state insurance, private insurance, TRICARE, and self-pay are all accepted, reducing a common barrier for Montanans who may otherwise delay or forgo detox and treatment due to financial concerns.
