Just up US-101 from Westlake Village, our outpatient rehab in Thousand Oaks runs drug and alcohol rehab across three levels, PHP, IOP, and standard outpatient, so you keep living at home and holding work or family while you attend. Most major insurance is accepted, and we verify your benefits before you start.
When Outpatient Rehab Is the Right Choice
For adults in Westlake Village, outpatient rehab is the level that treats a drug or alcohol problem without pulling you out of your life. It fits when you have a stable home and a job, a family, or a business you cannot leave for a month, and it is the usual next step once a detox or residential stay is behind you. You keep sleeping in your own bed and drive the short stretch of US-101 to the Thousand Oaks center for sessions, then head home the same day.
Outpatient is not the place to start if you are in active withdrawal or need supervision through the night. When that is the case, we help arrange a medically supervised detox or a residential stay first, then bring you into our program once you are stable. We treat adults 18 and older and do not run a teen or adolescent track. Veterans and active-duty service members can join our dedicated veterans and active-duty program.
Drug and Alcohol Rehab, Not Physical or Nursing Rehab
"Rehab" near Westlake Village can mean two very different things, so to be clear: this is addiction treatment at a licensed drug and alcohol rehabilitation center, not physical therapy or skilled-nursing rehabilitation. We treat drug and alcohol use disorders, not post-surgical recovery or mobility rehab. On the addiction side we work with alcohol, opioids including fentanyl and prescription painkillers, cocaine, methamphetamine and other stimulants such as Adderall, cannabis, and nicotine, and we treat co-occurring conditions such as depression, anxiety, trauma and PTSD, bipolar disorder, and ADHD on a parallel mental health track when that fits you.
The Outpatient Levels We Offer Near Westlake Village
We run three outpatient levels under one roof, and you move down through them as you steady out. What changes from one level to the next is how many hours a week you spend in treatment; the clinical team, the therapies, and the standard of care stay the same across all three.
| Level of care | What it involves |
|---|---|
| Partial hospitalization (PHP) | The most structured outpatient level, during the day on weekdays |
| Intensive outpatient (IOP) | Fewer weekly hours, built around a job or school |
| Outpatient (OP) | Lighter, longer-term relapse-prevention support, including evening sessions |
Most people move from PHP to IOP to standard outpatient as they stabilize. Because we run the full continuum in one place, the same team carries you from the most structured day treatment down to relapse-prevention outpatient, rather than handing you off or stopping at a single level. If you need a medically supervised detox or an inpatient stay before outpatient care, we coordinate that referral first and then step you into our program.
Outpatient vs Inpatient Rehab
The choice between outpatient and inpatient rehab comes down to where you live during treatment. Outpatient keeps you in Westlake Village, in your own home and routine, driving to Thousand Oaks for scheduled sessions. Inpatient or residential means moving into a facility around the clock, usually for weeks. For someone with a steady home and work or family nearby, outpatient is the fit; when withdrawal is active or home is not a safe place to get sober, inpatient comes first. We provide the outpatient side and refer out for detox or residential when that is the safer place to start.
| Outpatient (Lotus) | Inpatient or residential | |
|---|---|---|
| Where you live | Home in Westlake Village | Inside the facility, full-time |
| Job and family | Stay in your routine | On hold for weeks |
| Right when | Home is stable and recovery can happen around it | Withdrawal is active or home is unsafe |
How We Treat Drug and Alcohol Addiction
Treatment for people who travel in from Westlake Village is built from evidence-based therapy and, where it helps, medication managed by our medical team. Cognitive behavioral therapy (CBT) is the backbone, used to catch the thoughts and situations that drive use and to build skills you practice between sessions. Dialectical behavior therapy (DBT) adds distress tolerance and emotion regulation. EMDR is available for trauma and PTSD that sit underneath addiction. For opioid and alcohol use disorders, medication-assisted treatment with Suboxone and Vivitrol is folded into counseling rather than run on its own. We also provide psychiatry and medication management, TMS for depression that has not responded to medication, and group, family, and individual therapy. Telehealth is available for some services, which helps when a daily drive is hard. Which of these make up your plan is decided at your assessment and adjusted as you progress.
Insurance for Westlake Village Residents
Most commercial insurance covers outpatient drug and alcohol rehab with prior authorization, and we handle the benefits check for you. Lotus Recovery works with most major insurers on both an in-network and out-of-network basis, including Blue Cross Blue Shield, Aetna, UnitedHealthcare, Optum, Blue Shield of California, Kaiser Permanente, GEHA, UMR, and Anthem. Network status varies from plan to plan, so we verify your specific benefits before treatment begins and tell you what your plan covers. Same-day and walk-in assessments are available, and you can start the benefits check by phone or through our online insurance form.

Reaching the Center From Westlake Village
Our center is not in Westlake Village itself. It is in neighboring Thousand Oaks, at 290 Conejo Ridge Avenue, a short drive up US 101. For much of Westlake Village it is a quick trip up the freeway, and because outpatient treatment means coming in for sessions and heading home afterward, a short, reliable trip is part of what keeps treatment going. We serve Westlake Village along with Thousand Oaks, Newbury Park, Oak Park, Agoura Hills, and Calabasas. The need is real across the area: Ventura County recorded 216 fatal overdoses in 2025, an 8 percent rise and the first increase after four straight years of decline, according to the Ventura County Medical Examiner's Office, with opioids involved in 145 of those deaths. Our office is open Monday through Friday from 9am to 9pm, and our admissions line is answered 24 hours a day.

Rehab Near Westlake Village: Common Questions
How Much Is a 30-Day Rehab Program?
Most commercial plans cover outpatient drug and alcohol rehab with prior authorization, so what you pay is usually your plan's deductible and coinsurance. We work with most major insurers on both an in-network and out-of-network basis, verify your specific benefits before you start, and explain what your plan covers. We do not run a 30-day inpatient program; the cost of one varies widely by facility and whether care is inpatient or outpatient.
How Long Can a Patient Stay in Inpatient Rehab?
Inpatient or residential stays are commonly 30, 60, or 90 days, set by medical necessity and what insurance authorizes. We are an outpatient program rather than an inpatient one, so if you need a residential stay or medically supervised detox first, we help arrange it and then step you into our outpatient care afterward.
What Are the Three Types of Rehab?
For addiction, care is usually grouped into three types: medically supervised detox, inpatient or residential rehab, and outpatient rehab. We provide the outpatient type across three levels, partial hospitalization (PHP), intensive outpatient (IOP), and standard outpatient (OP), and we coordinate detox or residential care when that is the safer place to begin.
Where Is the Rehab if It Serves Westlake Village?
Our center is in Thousand Oaks, at 290 Conejo Ridge Avenue, a short drive from Westlake Village up US 101. We serve Westlake Village residents from that location rather than from a separate office in the city.
What Types of Drug and Alcohol Addiction Do You Treat?
We treat alcohol and a range of drugs: opioids including fentanyl and prescription painkillers, cocaine, methamphetamine and other stimulants such as Adderall, cannabis, and nicotine. When a mental health condition such as depression, anxiety, or PTSD sits alongside the substance use, we treat both together rather than sending you between providers.
Is Medication-Assisted Treatment Available?
Yes. For opioid and alcohol use disorders, our medical team offers medication-assisted treatment with Suboxone and Vivitrol, paired with counseling rather than used on its own. Whether it belongs in your plan is decided with you at your assessment.
What Should I Expect at the First Visit?
Your first step is a clinical assessment, often the same day you call, that sets your starting level of care and builds a weekly schedule around your work, school, or family. We verify your insurance before treatment begins and tell you what your plan covers, and same-day and walk-in assessments are available.
