Sanctuary Treatment Center provides multiple levels of care for adults seeking alcohol and drug rehab in Los Angeles. Treatment intensity can vary significantly depending on a person’s substance use, withdrawal risk, mental health needs, treatment history, recovery environment, and overall stability.
Some people may need the structure of detox or residential treatment before transitioning into outpatient care. Others may be appropriate for Partial Hospitalization (PHP), Intensive Outpatient (IOP), or standard outpatient treatment from the beginning.
Our goal is to help each client enter treatment at an appropriate level of care and transition to greater independence as recovery progresses.
Levels of care available through Sanctuary Treatment Center include:
- Medical detox
- Residential treatment
- Partial Hospitalization Program (PHP)
- Intensive Outpatient Program (IOP)
- Outpatient treatment
- Medication-Assisted Treatment when clinically appropriate
- Aftercare and continuing treatment planning
Understanding Addiction Treatment Levels of Care
Addiction treatment is not one single type of program.
Levels of care describe how much structure, supervision, clinical support, and weekly treatment a person receives. Someone who is medically unstable or at risk for significant withdrawal generally requires a different treatment setting than someone who is stable, living in a supportive environment, and ready to begin rebuilding everyday routines.
The appropriate level of care can also change throughout treatment.
A client may begin with detox, transition into residential treatment, continue into PHP or IOP, and eventually move into less intensive outpatient care.
This step-down approach allows treatment to evolve alongside the client’s clinical progress.
Substances We Treat at Sanctuary
Sanctuary Treatment Center provides treatment for alcohol and a wide range of substance use disorders. Our programs can support individuals struggling with:
- Heroin Addiction
- Meth Addiction
- Prescription Drug Addiction
- Marijuana Addiction
- Synthetic and Designer Drugs
How Is the Right Level of Care Determined?
You do not need to decide which program you need before contacting Sanctuary Treatment Center.
Our clinical and admissions teams evaluate several factors when determining an appropriate starting level of care, including:
- Current alcohol or drug use
- Frequency and amount of use
- Withdrawal symptoms or withdrawal risk
- Recent overdose history
- Physical health
- Mental health symptoms
- Current medications
- Previous treatment
- History of relapse
- Ability to remain stable outside treatment
- Home and recovery environment
- Family and social support
- Safety concerns
A person with significant withdrawal risk may need detox before beginning another level of care. Someone who is medically stable but needs substantial structure may be more appropriate for residential treatment or PHP.
People who have greater stability and support may be able to participate in IOP or outpatient care.
The recommendation can change as treatment progresses.
Moving Through the Continuum of Care
Recovery often involves more than one level of treatment.
A typical progression might look like:
Detox → Residential Treatment → PHP → IOP → Outpatient Care → Aftercare
Not every client will need every stage.
Some people may enter at PHP or IOP. Others may require a longer period of residential treatment or may transition between levels differently based on their progress.
The purpose of a continuum of care is not to force every client through the same sequence. It is to provide enough flexibility to increase or decrease support as clinical needs change.
Treatment for Co-Occurring Mental Health Needs
Substance use and mental health concerns frequently occur together.
Depression, anxiety, trauma, mood symptoms, emotional dysregulation, and other mental health concerns can influence substance use and recovery.
Sanctuary Treatment Center can incorporate dual diagnosis treatment when substance use and mental health symptoms overlap.
Addressing both concerns can help clients better understand the patterns contributing to substance use and develop healthier ways of managing stress, emotions, relationships, and other triggers.
Find the Right Level of Addiction Treatment in Los Angeles
Knowing that you need help does not mean you need to know exactly which type of treatment to choose.
Sanctuary Treatment Center provides multiple levels of alcohol and drug rehab in Los Angeles, allowing care to be matched to a person’s current needs and adjusted as recovery progresses.
Our admissions team can help you understand the differences between detox, residential treatment, PHP, IOP, and outpatient care and discuss what level may be appropriate based on your situation.
Call Sanctuary Treatment Center or verify your insurance to begin the admissions process.
Frequently Asked Questions About Rehab Levels of Care
What is the highest level of care for addiction treatment?
Medical detox and residential treatment generally provide the greatest amount of structure and supervision.
Detox focuses primarily on safely managing withdrawal and achieving medical stability. Residential treatment provides 24-hour structure while clients participate in ongoing addiction treatment.
What is the difference between residential treatment and PHP?
Residential treatment requires clients to live within a structured treatment setting.
PHP provides intensive daytime programming but allows clients to live outside the treatment facility when clinically appropriate.
PHP is often used after residential treatment as clients become more independent.
What is the difference between PHP and IOP?
PHP provides more weekly treatment hours and a higher degree of structure.
Sanctuary’s PHP may involve up to approximately 30 hours of programming each week, while IOP generally involves approximately 9 to 15 hours.
Can I start treatment in IOP?
Yes, some people may be appropriate for IOP without first completing detox, residential treatment, or PHP.
The appropriate starting point depends on withdrawal risk, stability, substance use severity, mental health needs, home environment, and other clinical factors.
How long does each level of care last?
There is no universal treatment timeline.
Length of stay or participation depends on the client’s clinical progress, treatment needs, level of care, insurance coverage, mental health needs, relapse risk, and recovery environment.
Can my level of care change during treatment?
Yes. Treatment recommendations should evolve as a person’s needs change. A client may move into a less intensive program as stability improves or require additional support if new clinical concerns emerge.
Do I need detox before entering rehab?
Not everyone requires detox.
An assessment can determine whether withdrawal can be safely managed without medical detox or whether supervised withdrawal management should occur before entering another level of treatment.
