Trillium Insurance Coverage for Drug & Alcohol Rehab

If you or someone you love is struggling with a substance use disorder and you receive health care coverage through the Oregon Health Plan (OHP), Trillium Community Health Plan may help cover the cost of addiction treatment at The Recovery Village Salem. Our facility accepts Trillium Medicaid CCO coverage for two critical levels of care: medical detox and SUD residential (inpatient) treatment.

Oregon ranks among the highest in the nation for illicit drug use disorder and has historically been last among all 50 states for treatment access, with nearly 80% of people who need substance use disorder care unable to receive it. The state recorded roughly 1,480 overdose deaths in the 12 months ending December 2024, down from 2023 but still far above pre-pandemic levels. If you have Trillium coverage, you have already cleared one of the biggest barriers to getting help. Our Recovery Advocates can verify your Trillium benefits, explain what is covered and walk you through the admissions process so you can focus on getting better rather than worrying about cost.

What Is Trillium Community Health Plan?

Trillium Community Health Plan is a Coordinated Care Organization (CCO) that manages health care benefits for members of the Oregon Health Plan, the state’s Medicaid program. Operated by Centene Corporation, one of the largest Medicaid managed care companies in the country, Trillium connects members to a network of medical, dental, behavioral health and substance use disorder treatment providers throughout Oregon.

The CCO model is central to how Oregon delivers Medicaid services. Instead of having medical care, mental health support and addiction treatment managed by separate entities, a CCO like Trillium coordinates all of these services under one umbrella. This integrated structure is particularly important for people dealing with addiction, because substance use disorders rarely exist in isolation. Many individuals also experience co-occurring mental health conditions such as depression, anxiety or PTSD, and a coordinated model helps ensure that both conditions are addressed together rather than separately.

Where Trillium Operates

Trillium currently serves OHP members across several regions of Oregon. Its service area includes Lane County, western Douglas County, western Linn County and, following its recent expansion, Clackamas, Multnomah and Washington counties in the Portland metro area. In February 2025, Trillium absorbed nearly 96,000 OHP members in Lane County who were previously covered by PacificSource Community Solutions, making it the sole CCO in that county and significantly increasing its total membership footprint across the state.

The Recovery Village Salem is located at 309 Lancaster Dr NE in Salem, Oregon, the state capital, situated in Marion County. Salem borders several of Trillium’s service area counties. Members assigned to Trillium as their CCO may be eligible for covered treatment at our facility depending on network status and authorization. Our admissions team works directly with Trillium to confirm your eligibility and initiate the authorization process.

What Trillium Covers at The Recovery Village Salem

The Recovery Village Salem accepts Trillium Community Health Plan coverage for two key levels of substance use disorder treatment. Both services are designed to address the most acute phases of addiction and lay the foundation for sustained recovery:

• Medical detox (ASAM Level 3.7-WM) – medically monitored inpatient withdrawal management.
• SUD residential treatment (ASAM Level 3.7R) – medically monitored intensive inpatient rehab for substance use disorders.

Medical Detox (ASAM Level 3.7-WM)

Medical detox, classified under the ASAM Criteria as Level 3.7-WM (medically monitored inpatient withdrawal management), is the clinical process of safely managing acute withdrawal symptoms under 24-hour medical supervision. It is typically the first step in treating addiction to substances that cause physical dependence, including alcohol, opioids such as heroin and fentanyl, benzodiazepines, methamphetamine and certain prescription medications.

During detox at The Recovery Village Salem, you live on-site while our clinical team continuously monitors your vital signs, hydration levels and neurological status. Physicians may prescribe medications to manage specific withdrawal symptoms, reduce cravings and prevent dangerous complications. The goal of detox is not simply to get substances out of your system — it is to stabilize you medically so you can safely transition into the therapeutic work of residential treatment.

What Withdrawal Looks Like by Substance

The detox experience varies significantly depending on which substance or combination of substances is involved. Understanding what to expect can help reduce the fear that often prevents people from seeking help.

Alcohol. Alcohol withdrawal is among the most medically dangerous forms of withdrawal. Symptoms typically begin six to twelve hours after the last drink, starting with tremors, anxiety, sweating, nausea and elevated heart rate. Symptoms usually peak between 24 and 72 hours and can include hallucinations and seizures. In the most severe cases, roughly 3–5% of patients develop delirium tremens (DTs), a potentially life-threatening condition characterized by severe confusion, fever and cardiovascular instability. Medical detox for alcohol addiction often involves benzodiazepines to prevent seizures, thiamine (vitamin B1) to prevent neurological damage, IV fluids for dehydration and continuous vital sign monitoring. Acute physical symptoms generally resolve within five to seven days, though some patients experience residual mood disturbances and sleep disruption for several weeks.

Opioids and fentanyl. Opioid withdrawal is intensely uncomfortable but rarely life-threatening when medically managed. For short-acting opioids like heroin and illicitly manufactured fentanyl, symptoms typically begin eight to 24 hours after the last dose and include severe muscle and bone pain, restlessness, insomnia, diarrhea, vomiting, cold flashes and powerful cravings. Symptoms peak in intensity between 36 and 72 hours and typically last seven to ten days, though some patients experience lingering symptoms for up to two weeks. During opioid detox, our physicians may prescribe buprenorphine (Suboxone) to reduce withdrawal symptoms and cravings, clonidine to ease anxiety and autonomic symptoms, and additional comfort medications for nausea, diarrhea and insomnia. Patients who are candidates for ongoing medication-assisted treatment (MAT) can be stabilized on buprenorphine during detox and continue it into residential care and beyond.

Benzodiazepines. Withdrawal from benzodiazepines such as Xanax, Valium or Klonopin can be medically complex and, like alcohol, carries a risk of seizures. Because of these dangers, benzodiazepine detox typically involves a slow, controlled taper rather than abrupt discontinuation. The timeline varies widely depending on the specific medication and duration of use, ranging from one to four weeks or longer. Our medical team develops an individualized tapering schedule to minimize risk and discomfort.

Methamphetamine and stimulants. Stimulant withdrawal does not carry the same seizure risk as alcohol or benzodiazepine withdrawal, but it produces a distinct pattern of symptoms that can be difficult to manage without support. The initial “crash” phase involves extreme fatigue, excessive sleep and increased appetite, followed by a prolonged period of depression, anxiety, irritability and intense cravings. Because there are no FDA-approved medications for stimulant withdrawal, medical detox focuses on supportive care, nutritional rehabilitation, sleep regulation and monitoring for suicidal ideation, which can emerge during the depressive phase.

Trillium covers medically monitored withdrawal management when clinical documentation supports that this level of care is the appropriate placement. The typical detox stay at our facility ranges from three to ten days, though it can be shorter or longer based on individual clinical need.

SUD Residential Treatment (ASAM Level 3.7R)

After completing detox, many patients transition directly into SUD residential treatment, also known as inpatient rehab. Trillium designates this as ASAM Level 3.7R — medically monitored intensive inpatient treatment for substance use disorders. During residential care, you continue to live at our Salem facility and participate in a structured daily program that addresses the psychological, emotional and behavioral dimensions of addiction that detox alone cannot resolve.

What a Day in Residential Treatment Looks Like

Residential treatment at The Recovery Village Salem follows a structured daily schedule designed to build therapeutic momentum while allowing adequate time for rest and reflection. While the exact schedule varies by the clinical needs of each patient, a representative day might include a morning check-in with nursing staff, individual therapy with a licensed counselor, two to three group therapy sessions focused on different evidence-based modalities, a psychoeducational lecture or skills workshop, recreational or wellness time (exercise, mindfulness, journaling) and an evening peer support or process group.

Evidence-Based Therapies Used in Residential Care

Our clinical team uses several evidence-based therapeutic approaches during residential treatment, including:

• Cognitive Behavioral Therapy (CBT) helps patients identify and change the distorted thought patterns and beliefs that drive substance use, teaching concrete skills for recognizing triggers, challenging automatic thoughts and developing healthier behavioral responses.
• Dialectical Behavior Therapy (DBT) focuses on building skills in mindfulness, distress tolerance, emotion regulation and interpersonal effectiveness, particularly for patients who struggle with emotional dysregulation or self-destructive behaviors.
• Motivational Interviewing (MI) is a collaborative counseling style that strengthens a patient’s own motivation and commitment to change by exploring their reasons for recovery and resolving ambivalence about treatment.
• Trauma-informed care recognizes that many people who develop substance use disorders have experienced significant trauma. Our clinical team screens for trauma history and incorporates trauma-informed approaches throughout treatment to avoid re-traumatization and promote healing.
• Relapse prevention planning equips patients with personalized strategies for maintaining sobriety after discharge, including trigger identification, coping skills, crisis contacts, medication plans and connections to community support resources.

Dual-Diagnosis Treatment for Co-Occurring Disorders

Substance use disorders frequently co-occur with mental health conditions. National data shows that roughly half of people with a severe mental illness also experience a substance use disorder, and the reverse is equally common. At The Recovery Village Salem, we provide integrated dual-diagnosis treatment in which both the addiction and the co-occurring mental health condition — whether it is depression, anxiety, PTSD, bipolar disorder or another diagnosis — are treated simultaneously by the same clinical team rather than in separate, disconnected programs.

This integrated approach matters because untreated mental health conditions are one of the most common drivers of relapse. A patient who completes SUD treatment but returns home with untreated depression or unresolved PTSD is at significantly higher risk of returning to substance use. By addressing both conditions together, dual-diagnosis care gives patients a stronger foundation for lasting recovery.

Trillium provides coverage for SUD residential treatment when it is determined to be medically necessary. Length of stay varies, but residential treatment commonly lasts between 14 and 45 days. Our clinical team submits concurrent review requests to Trillium at regular intervals throughout your stay to demonstrate ongoing medical necessity and secure continued authorization.

How Your Clinical Needs Are Assessed: The ASAM Criteria

Both detox and residential treatment placement decisions are guided by the ASAM Criteria, the most widely used framework for matching patients to the appropriate level of addiction care. The ASAM Criteria evaluates each patient across six dimensions:

• Dimension 1 — Acute intoxication and/or withdrawal potential. Your current level of intoxication and the risks of withdrawal based on the substances used, the amounts and the duration.
• Dimension 2 — Biomedical conditions and complications. Any medical conditions that need to be managed during treatment, such as liver disease, heart conditions, diabetes, chronic pain or infectious diseases.
• Dimension 3 — Emotional, behavioral or cognitive conditions. Co-occurring mental health conditions like depression, anxiety, PTSD or psychotic symptoms, as well as any history of self-harm or suicidal ideation.
• Dimension 4 — Readiness to change. Your level of motivation and engagement with treatment, as well as any ambivalence or external pressures that need to be addressed.
• Dimension 5 — Relapse, continued use or continued problem potential. Your likelihood of relapse without a structured level of care, including your history of prior treatment episodes and outcomes.
• Dimension 6 — Recovery/living environment. Your home and social environment, including people, places or situations in your daily life that could either support or undermine recovery.

Each dimension is scored based on the information gathered during your comprehensive intake assessment. The combined picture across all six dimensions determines whether medical detox, residential treatment or a different level of care is the most clinically appropriate placement. This assessment is what Trillium relies on when reviewing authorization requests — it is the clinical backbone of every coverage decision.

How Trillium Authorization Works

Because Trillium is a Medicaid managed care plan, substance use disorder treatment services at the residential level require prior authorization. Understanding how this process works can reduce uncertainty and help you feel more confident about beginning treatment.

Key Steps in the Trillium Authorization Process

1. Eligibility verification. Your Recovery Advocate contacts Trillium to confirm your active OHP enrollment and verify that Trillium is your assigned CCO. This can usually be completed within minutes over the phone or through Trillium’s electronic eligibility system.
2. Clinical assessment. When you arrive at our facility, our medical and clinical team conducts the comprehensive biopsychosocial assessment described above, scoring each of the six ASAM dimensions with detailed clinical documentation.
3. Authorization request. Our admissions team submits the prior authorization request to Trillium’s Medical Management department, including all supporting clinical documentation. Standard authorization requests are typically processed within two business days. Urgent requests — including situations where a patient needs immediate stabilization — can often be expedited.
4. Initial authorization. Trillium issues an authorization for a defined number of treatment days based on the clinical information submitted. This initial authorization covers the beginning of your detox or residential stay.
5. Concurrent review. As your treatment progresses, our clinical team submits concurrent review requests at prescribed intervals, typically every seven days for SUD residential care. These reviews include updated clinical notes documenting your progress, ongoing symptoms, treatment participation and continued medical necessity, which Trillium uses to authorize additional days of treatment.
6. Discharge planning. As you approach clinical readiness for a lower level of care, your treatment team develops a comprehensive discharge plan. This plan is shared with Trillium to support continuity of care after your residential stay.

You do not need to manage any part of this process yourself. Our team handles every interaction with Trillium on your behalf so you can focus entirely on your recovery.

What You Will Pay Out of Pocket

One of the most important advantages of receiving care through the Oregon Health Plan is that OHP members generally pay little to nothing for covered services. Under OHP, there are no monthly premiums. Copayments for most behavioral health services are either waived entirely or capped at a nominal dollar amount, typically no more than a few dollars per service. For SUD treatment that has been authorized as medically necessary through Trillium, most members will owe nothing at the point of service.

Coverage details can vary slightly depending on your specific OHP eligibility category, such as whether you are enrolled through the standard Oregon Health Plan or through a specialized eligibility pathway. Our Recovery Advocates will confirm your exact cost responsibility before treatment begins so there are no surprises. In our experience, the vast majority of Trillium OHP members are able to access detox and residential treatment with zero out-of-pocket cost.

Transportation to Treatment: Trillium’s NEMT Benefit

Getting to a treatment facility can be a significant barrier, especially for people in crisis. Trillium Community Health Plan includes a Non-Emergency Medical Transportation (NEMT) benefit for OHP members. This benefit provides free rides to and from OHP-covered medical appointments, including substance use disorder treatment.

If you need transportation to The Recovery Village Salem for your admission, Trillium’s NEMT benefit may cover the cost. The ride service can arrange transportation by taxi, ride service vehicle, public transit pass or even mileage reimbursement if you drive yourself. Rides must generally be scheduled at least 24 hours in advance, though same-day and urgent trips — including hospital discharges — may be accommodated.

The specific NEMT ride service varies depending on which Trillium service area you live in. For members in Lane County, the ride service is RideSource at 877-800-9899. For members in the Portland tri-county area (Clackamas, Multnomah, Washington), the ride service is MTM at 877-583-1552. You can also call Trillium Member Services at 877-600-5472 for help arranging transportation. If an attendant or family member needs to travel with you, their ride is covered at no additional cost.

Your Rights as a Trillium OHP Member

As a Trillium Community Health Plan member, you have specific rights protected under Oregon Medicaid law and the Oregon Health Authority’s CCO contract. When it comes to substance use disorder treatment, some of the most important rights to know include:

• Right to self-refer for SUD services. Oregon Health Plan rules generally allow members to self-refer for substance use disorder treatment without needing a formal referral from a primary care provider. This means you can contact The Recovery Village Salem directly to begin the admissions process.
• Right to timely access. Trillium is required to provide access to medically necessary services within specific timeframes. Urgent behavioral health needs must be addressed within 24 hours.
• Right to appeal a denial. If Trillium denies a prior authorization request, you have the right to receive a written explanation of the denial and the right to appeal. You also have the right to request a state fair hearing through the Oregon Health Authority if you disagree with the appeal outcome.
• Right to language access. Trillium must provide interpreter services and translated materials at no cost to members with limited English proficiency. This applies to all aspects of care, including substance use disorder treatment.
• Right to privacy. All substance use disorder treatment records are protected by both HIPAA and the more stringent federal 42 CFR Part 2 confidentiality regulations. Your treatment information cannot be shared without your written consent, except in limited circumstances defined by law.

Steps to Use Your Trillium Coverage

If you are ready to seek help with a substance use disorder and you have Trillium OHP coverage, these steps can help you get started:

1. Confirm your OHP enrollment. Make sure your Oregon Health Plan coverage is active and that Trillium Community Health Plan is your assigned CCO. You can check this through the OHP member portal, by calling OHP directly at 800-699-9075 or by calling Trillium Member Services at 877-600-5472.
2. Contact The Recovery Village Salem. Call our Recovery Advocates to begin the verification process. We will confirm your Trillium enrollment, review your benefits and discuss treatment options. You can also complete our online insurance verification form for a confidential, no-obligation benefits check.
3. Arrange transportation if needed. If you do not have a way to get to our facility, contact Trillium’s NEMT ride service to arrange a free ride. See the transportation section above for phone numbers by service area.
4. Arrive for your clinical assessment. When you arrive at our facility, our medical team conducts the comprehensive evaluation that supports the authorization request. Many patients are able to begin medical detox the same day. To help you prepare for what to bring and what to expect during your first hours at the facility, visit our What to Expect page.
5. Begin treatment. Once authorization is confirmed, your individualized treatment plan begins. Our team manages all Trillium communications throughout your stay, including concurrent reviews and discharge planning.

What Happens After Residential Treatment?

Completing detox and residential care is a critical milestone, but recovery is an ongoing process that benefits from continued support. Before you leave The Recovery Village Salem, your clinical team develops a comprehensive aftercare plan tailored to your needs. This plan may include:

• Referrals to outpatient treatment providers in your home community, including intensive outpatient programs (IOP) if clinically indicated.
• Connections to mutual support groups such as Alcoholics Anonymous, Narcotics Anonymous or SMART Recovery.
• A medication management plan if you are taking buprenorphine, naltrexone or psychiatric medications.
• Coordination with your Trillium-assigned primary care provider to help keep your medical and behavioral health care aligned after discharge.
• Guidance on accessing community recovery resources, peer support services and sober housing options, when appropriate.

If your Trillium plan covers additional outpatient levels of care, your treatment team can help facilitate that transition. Our goal is to ensure that no one leaves our facility without a clear path forward.

Why Treatment Matters Now in Oregon

Oregon’s substance use crisis has reached a level of urgency that few other states face. Overdose deaths in the state rose from 280 in 2019 to more than 1,800 in 2023 — a more than sixfold increase in just four years — driven primarily by illicitly manufactured fentanyl. Although provisional data shows a decline in Oregon overdose deaths through 2024, the roughly 1,480 fatalities recorded that year remain far above pre-pandemic levels.

Beyond opioids, Oregon faces severe challenges across multiple substance categories. Methamphetamine misuse remains widespread, and alcohol addiction continues to be a leading cause of preventable death in the state, contributing to thousands of deaths each year. Fentanyl now accounts for the majority of opioid-related fatalities in Oregon, and its presence in the illicit drug supply has made every episode of substance use more dangerous than it was even a few years ago.

Despite these staggering numbers, Oregon has historically ranked near the bottom nationwide for treatment access, with more than half of Oregonians who need SUD treatment unable to receive it. The expansion of Medicaid coverage through CCOs like Trillium is one of the state’s most important tools for closing this gap. If you have Trillium OHP coverage and you or someone you love is dealing with addiction, the coverage to get help likely already exists. The Recovery Village Salem is here to help you use it.

Frequently Asked Questions About Trillium Coverage

Does Trillium cover drug and alcohol rehab?

Yes. Trillium Community Health Plan covers substance use disorder treatment services when they are determined to be medically necessary. At The Recovery Village Salem, Trillium coverage is accepted for medical detox (ASAM Level 3.7-WM) and SUD residential treatment (ASAM Level 3.7R). Authorization is required and is based on a clinical assessment using the ASAM Criteria and Oregon Health Authority guidelines.

Do I need a referral from my primary care provider?

In most cases, you do not need a formal referral from your primary care provider to access SUD treatment. Oregon Health Plan rules generally allow members to self-refer for substance use disorder services, recognizing that barriers to entry can be life-threatening when someone is ready for treatment. However, notifying your PCP or contacting Trillium Member Services before admission can help ensure a smooth authorization process. Our admissions team can also initiate the process directly with Trillium on your behalf.

Will I owe anything out of pocket with Trillium Medicaid?

OHP members typically have zero or very low out-of-pocket costs for covered behavioral health services, including substance use disorder treatment. Copayments for most SUD services under Trillium are either waived or capped at a small amount under Oregon Medicaid rules. There are no monthly premiums for OHP coverage. Our Recovery Advocates will confirm your specific cost responsibility before treatment begins.

What levels of care does Trillium cover at The Recovery Village Salem?

The Recovery Village Salem currently accepts Trillium Community Health Plan for two levels of care: medical detox (medically monitored inpatient withdrawal management) and SUD residential treatment (medically monitored intensive inpatient services). These two levels address the most acute phases of addiction recovery, from safely managing withdrawal through intensive therapeutic programming. If you need additional levels of care such as outpatient treatment after discharge, our team can help connect you with appropriate providers in your area.

How long will Trillium cover my stay?

The length of your authorized stay depends on your clinical needs as assessed by your treatment team and approved by Trillium through their utilization management process. Medical detox typically lasts three to ten days depending on the substance and severity of dependence. SUD residential stays commonly range from 14 to 45 days. Our clinical staff submits concurrent review requests to Trillium throughout your treatment, typically every seven days, to request continued authorization when extended care is medically necessary.

What if my Trillium authorization is denied?

If Trillium denies an authorization request, you have the right to appeal the decision. Trillium is required to provide a written explanation of any denial, including the clinical rationale. Our clinical team can assist you in understanding the reason for the denial, gathering additional documentation and filing an appeal. Oregon Health Plan members also have the right to request a state fair hearing through the Oregon Health Authority if they disagree with a coverage decision.

Can I walk in for treatment with my Trillium card?

Yes. The Recovery Village Salem accepts walk-in patients. If you arrive at our facility with active Trillium OHP coverage, our admissions team will work to verify your benefits and initiate authorization as quickly as possible. Calling ahead can help expedite the process, but we understand that the decision to seek help sometimes cannot wait.

Does Trillium cover medications used during detox and residential treatment?

Medications administered as part of your inpatient medical detox or residential treatment are generally included in the facility’s per-diem rate and do not require a separate pharmacy prior authorization. This includes medications for withdrawal management (such as benzodiazepines for alcohol detox), symptom stabilization and medication-assisted treatment (MAT) such as buprenorphine. If you are prescribed ongoing medications at discharge, those prescriptions are filled through Trillium’s pharmacy benefit using their Preferred Drug List. Our clinical team coordinates with Trillium to help prevent any gap in medication access at discharge.

Can Trillium help me get to The Recovery Village Salem?

Yes. Trillium provides a Non-Emergency Medical Transportation (NEMT) benefit that covers free rides to OHP-covered medical appointments, including substance use disorder treatment. Depending on your service area, you can arrange a ride through RideSource (Lane County: 877-800-9899) or MTM (Portland tri-county: 877-583-1552). Call Trillium Member Services at 877-600-5472 if you need help arranging transportation. Rides should be scheduled at least 24 hours in advance when possible, though urgent same-day trips may be accommodated.

What if I am not sure Trillium is my CCO?

If you are unsure which CCO you are assigned to, you can check by logging into the OHP member portal, calling OHP at 800-699-9075 or calling Trillium Member Services at 877-600-5472. You can also call The Recovery Village Salem, and our team will help you verify your CCO assignment as part of the admissions process.

What happens if I need to leave treatment early?

Patients at The Recovery Village Salem can choose to leave treatment at any time, even against medical advice, as long as they do not pose an immediate risk to themselves or others. However, completing your full recommended course of treatment significantly reduces the risk of relapse and overdose. If you are considering leaving early, we encourage you to discuss your concerns with your treatment team — often, adjustments to your treatment plan can address the underlying issue without interrupting your care.
