About

About Rimrock Foundation

Rimrock Foundation is a CARF-accredited substance use treatment facility located at 1231 North 29th Street in Billings, Montana. Positioned as a leading addiction treatment resource in the region, Rimrock serves individuals across Billings, Bozeman, and the broader Montana area who need structured, clinically supervised care — from the earliest stage of withdrawal through longer-term recovery programming.

The facility offers a full continuum of care built around medical detox as its entry point for many patients. Beyond medically supervised detox, Rimrock provides residential treatment, a standard outpatient program, an intensive outpatient program (IOP), and day treatment — giving patients options at every level of clinical need. This range means someone can step down from inpatient detox directly into a higher level of outpatient care without leaving the same provider network.

Treatment at Rimrock incorporates Medication Assisted Treatment (MAT), Cognitive Behavioral Therapy (CBT), and family therapy. The facility also addresses co-occurring disorders and dual diagnosis, trauma and PTSD, and gambling addiction alongside substance use — reflecting a recognition that many people entering detox or residential care carry multiple clinical needs at once.

Rimrock serves a notably broad population: adults, young adults ages 18–25, seniors, men, women, pregnant women, veterans, court-ordered individuals, and people with HIV/AIDS or who are deaf or hard of hearing. The facility accepts Medicaid, state insurance, TRICARE, private insurance, and self-pay. Insurance verification is handled through the Admissions Department, and payment arrangements are confirmed with the Business Office prior to admission.

Medical Detox and Withdrawal Management at Rimrock Foundation

For individuals facing acute withdrawal, Rimrock Foundation offers medical detox as the clinical starting point in its care continuum. Medically supervised detox provides a structured setting where withdrawal can be managed before a patient transitions into the next appropriate level of care — whether that is residential treatment, day treatment, or an intensive outpatient program.

Rimrock also integrates Medication Assisted Treatment (MAT) into its programming, which supports patients whose withdrawal and ongoing treatment may benefit from FDA-recognized pharmacological protocols. The combination of medical detox and MAT positions Rimrock as a clinically oriented option for people who need more than peer support during early recovery.

Levels of Care: From Inpatient Detox to Outpatient Programs

Rimrock Foundation operates across five distinct levels of care: medical detox, residential treatment, outpatient program, intensive outpatient program (IOP), and day treatment. This structure allows clinicians to place patients at the appropriate level of intensity and step them down gradually as stability improves — reducing the gaps that often lead to relapse during care transitions.

The facility serves individuals across Billings, Bozeman, and throughout Montana, making it one of the more accessible multi-level treatment providers in the state. For families researching options, the ability to transition a loved one from inpatient detox into residential or outpatient care within the same organization can reduce logistical and clinical friction during a critical period.

Co-Occurring Disorders and Specialized Population Services

Rimrock treats co-occurring disorders and dual diagnosis, trauma and PTSD, and gambling addiction — conditions that frequently appear alongside substance dependence and complicate detox and early recovery. Addressing these conditions within the same treatment setting, rather than referring out, is a meaningful clinical distinction for patients whose needs go beyond withdrawal management alone.

The facility explicitly serves veterans, pregnant women, seniors, young adults, court-ordered individuals, and people with HIV/AIDS or hearing impairments. TRICARE is accepted, which directly supports access for active-duty military and veteran patients. This breadth of population-specific programming is relatively uncommon among Montana detox and treatment providers.

Payment Options and Admissions at Rimrock Foundation

Rimrock Foundation accepts Medicaid, state insurance, TRICARE, private insurance, and self-pay. For those unsure whether their coverage applies, the Admissions Department offers insurance verification — a practical first step for families or individuals trying to assess cost before committing to a program.

Per the facility's own policy, payment arrangements — whether through an insurance carrier, employer, family, or the patient directly — must be confirmed with the Business Office prior to admission. Prospective patients or families can reach Rimrock at (406) 248-3175 or by email at info@rimrock.org to begin that process.
