Lewis and Clark Behavioral Hlth Servs Alcohol and Drug Program

For families in the Yankton area researching addiction treatment options, one of the practical challenges is finding a recovery center that can support a person across multiple stages of the process — not just the acute first days, but the weeks and months that follow. Lewis and Clark Behavioral Health Services addresses this by offering medical detox, residential treatment, an outpatient program, and an intensive outpatient program (IOP) under one roof in Yankton, SD.

This structure matters because the transition between levels of care is often where continuity breaks down. Moving from detox into residential treatment, and then stepping down into an outpatient program or IOP, within the same facility means the clinical team already knows the person's history and treatment context. For residents of Yankton, Vermillion, Lake Andes, and the surrounding region, Lewis and Clark Behavioral Health Services represents one of the more complete substance abuse treatment options available locally.

A significant share of people entering addiction treatment are also managing untreated or undertreated mental health conditions. Lewis and Clark Behavioral Health Services specifically treats co-occurring disorders and dual diagnosis cases, as well as trauma and PTSD alongside substance use disorders. This isn't an add-on — it's built into the center's clinical focus across levels of care.

The use of Cognitive Behavioral Therapy (CBT) as a core therapeutic method reflects a structured, skills-based approach to recovery that addresses both thought patterns and behaviors. CBT is well-suited to dual diagnosis treatment because it can be applied to both substance use and mental health symptoms simultaneously, making it a practical fit for a population that often arrives with complex, layered needs.

Lewis and Clark Behavioral Health Services works with a wider range of populations than many regional treatment centers. The facility accepts adolescents, young adults ages 18–25, women, pregnant women, seniors and older adults, individuals who are Deaf or hard of hearing, and those entering treatment through court order. This breadth reflects a commitment to accessibility across the communities of southeastern South Dakota.

On the financial side, the center accepts Medicaid, Medicare, TRICARE, private insurance, state insurance, self-pay, and sliding scale fees, and also offers financial assistance. Critically, the center's stated policy is that services are provided regardless of ability to pay — a meaningful commitment for individuals and families who may be concerned that cost will be a barrier to accessing residential treatment or an outpatient program.

One of the most important questions people ask when choosing a rehab is what comes after inpatient treatment. At Lewis and Clark Behavioral Health Services, the existence of both an outpatient program and an intensive outpatient program (IOP) means that step-down care can happen within the same recovery center. Rather than completing residential treatment and then searching for a separate outpatient provider, individuals can transition into a less intensive level of care with the same clinical team in Yankton, SD.

This kind of continuity is particularly valuable for people returning to communities in southeastern South Dakota — including Vermillion and Lake Andes — where options for specialized substance abuse treatment may be more limited. Maintaining a consistent therapeutic relationship through CBT-based outpatient programming can support the longer-term recovery work that begins after detox and residential treatment conclude.
