Why Medication-Assisted Treatment Matters Behind Bars

Medication-assisted treatment, often called MAT or MOUD when referring specifically to opioid use disorder, is one of the most evidence-based approaches to treating addiction. In correctional settings, it can reduce withdrawal, lower overdose risk, and help people continue care after release. That matters because incarceration often interrupts treatment at the exact moment when continuity is most important.

In Montana, the need is especially clear. State health officials say incarcerated people have disproportionately high behavioral health needs, and a large share of people processed through the Department of Corrections have offenses related to substance use. Montana also reports a much higher overdose risk after release from custody, which makes treatment continuity a public safety issue as much as a health issue.

How Montana Defines the Problem

Montana's Department of Public Health and Human Services describes MOUD as the use of FDA-approved medications, including buprenorphine and methadone, together with therapy to support recovery from opioid use disorder. The state also notes that these medications can reduce cravings and withdrawal, improve survival, and decrease opioid-related overdose deaths and criminal justice involvement. ([dphhs.mt.gov](https://dphhs.mt.gov/BHDD/SubstanceAbuse/))

That framing is important because correctional health care has historically focused on crisis management rather than long-term treatment. In a jail or prison, untreated withdrawal can lead to medical complications, behavioral instability, and a higher chance that a person will return to illicit opioid use after release. MAT helps address those risks in a structured, medically supervised way. This is a general inference based on the state's stated goals and the known role of MOUD in treatment.

What Montana's Department of Corrections Is Doing Now

Montana's Department of Corrections has an active MAT policy, DOC 4.5.56A, with a revision date of April 24, 2026. The policy states that the department will provide access to MAT for patients who meet criteria and agree to participate in treatment for opioid use disorder and/or alcohol use disorder. It applies to all secure facilities, including department-owned and contracted facilities. ([cor.mt.gov](https://cor.mt.gov/_docs/Policies/Chapter4/DOC-4.5.56A-Medication-Assisted-Treatment-MAT-Program.pdf))

The policy also says patients are screened upon entry for evidence of substance use disorder, and that ASAM criteria, validated assessment tools, urine drug screens, community records, overdose history, and the Montana Prescription Monitoring System may be used in diagnosis and treatment planning. In other words, Montana's correctional MAT program is not a casual add-on; it is built into intake screening, clinical evaluation, and ongoing care. ([cor.mt.gov](https://cor.mt.gov/_docs/Policies/Chapter4/DOC-4.5.56A-Medication-Assisted-Treatment-MAT-Program.pdf))

As of the state's 2024 Substance Use Disorder Strategic Plan, the Department of Corrections was offering MAT/MOUD in three secure care correctional facilities, and contracted facilities had also begun to offer these services. That suggests Montana has moved beyond pilot-stage thinking and is building a broader correctional treatment model.

The Reentry Connection: Why Release Planning Is Critical

One of the most important developments in Montana is the state's reentry-focused behavioral health work. Montana says it became the third state to receive federal approval to waive the inmate exclusion and provide a limited set of Medicaid-covered services to adults in state prisons with a behavioral health need during the 30 days before release. Those services can include case management, medication-assisted treatment, optional in-reach clinical consultation, and a 30-day supply of medication in hand at release. ([dphhs.mt.gov](https://dphhs.mt.gov/HeartInitiative/JusticeInvolved))

That matters because the period immediately after release is one of the highest-risk times for overdose and other health crises. Montana's own materials point to a 2020 study showing a 27-times higher overdose rate among people released from the Department of Corrections compared with the general population. The state's reentry services are designed to reduce gaps in care and improve the handoff from prison to community treatment. ([dphhs.mt.gov](https://dphhs.mt.gov/HeartInitiative/JusticeInvolved))

What This Means for Jails in Montana

Montana's most detailed public policy language is aimed at the Department of Corrections and secure facilities, but the broader lesson for county jails is clear: correctional health care is increasingly expected to support evidence-based addiction treatment, not just detoxification. Jails often see shorter stays than prisons, which can make treatment continuity harder. Still, the same principles apply: screen early, verify existing prescriptions, coordinate with community providers, and avoid abrupt treatment interruptions whenever possible. This is an inference from Montana's correctional policy and statewide treatment framework. ([cor.mt.gov](https://cor.mt.gov/_docs/Policies/Chapter4/DOC-4.5.56A-Medication-Assisted-Treatment-MAT-Program.pdf))

For local jails, the practical challenge is often logistics. Facilities may need prescribers, pharmacy access, secure medication storage, and protocols for transfer and release. They also need clear communication with community treatment programs so that someone who starts or continues MAT in custody can keep going after discharge. Montana's emphasis on warm handoffs and discharge planning points in that direction. ([dphhs.mt.gov](https://dphhs.mt.gov/HeartInitiative/JusticeInvolved))

Why MAT in Corrections Is a Public Safety Strategy

Medication-assisted treatment is not only about individual health. Montana's public health materials note that MOUD can decrease opioid use, overdose deaths, and involvement with the criminal justice system. That makes correctional MAT part of a broader public safety strategy: fewer overdoses, fewer emergency interventions, and a better chance that people leaving custody can stabilize their lives. ([dphhs.mt.gov](https://dphhs.mt.gov/BHDD/SubstanceAbuse/))

Montana's 2024 strategic plan also shows the state is investing in the workforce and infrastructure needed to support treatment, including training for medical professionals and expansion of peer support. Those investments matter because correctional MAT works best when it is connected to a larger treatment ecosystem rather than operating in isolation. ([dphhs.mt.gov](https://dphhs.mt.gov/assets/publichealth/EMSTS/opioids/SUDsStrategicPlan2024.pdf))

Challenges That Still Remain

Even with policy progress, implementation is not simple. Rural geography, staffing shortages, limited behavioral health capacity, and the need for secure medication management can all make correctional MAT difficult to scale. Montana's own materials show that many residents with substance use disorder still are not receiving treatment, which means the correctional system is only one part of a much larger access problem. ([dphhs.mt.gov](https://dphhs.mt.gov/assets/publichealth/EMSTS/opioids/SUDsStrategicPlan2024.pdf))

There is also a distinction between having a policy and delivering consistent care in every facility. Public documents show that Montana's DOC policy applies to secure facilities and that contracted facilities are included as specified in contract, but the day-to-day experience can still vary by location, staffing, and clinical resources. That is a cautious inference based on the policy structure. ([cor.mt.gov](https://cor.mt.gov/_docs/Policies/Chapter4/DOC-4.5.56A-Medication-Assisted-Treatment-MAT-Program.pdf))

The Bottom Line for 2026

As of today, Montana is actively treating medication-assisted treatment as a core correctional health tool rather than an optional extra. The state has a current DOC MAT policy, statewide MOUD guidance, and a reentry-focused Medicaid waiver that can support treatment continuity before release. Together, those steps show a clear direction: more screening, more access, and better transitions from custody to community care. ([cor.mt.gov](https://cor.mt.gov/_docs/Policies/Chapter4/DOC-4.5.56A-Medication-Assisted-Treatment-MAT-Program.pdf))

For Montana jails and prisons, the takeaway is straightforward. If the goal is to reduce overdose, improve recovery, and support safer reentry, medication-assisted treatment is one of the strongest tools available. The challenge now is making sure that access is consistent, timely, and connected to care after release.
