The first real decision in addiction recovery is which level of care to start with. Get this wrong on the high side and you spend money and time on an environment more intensive than you need. Get it wrong on the low side and you set yourself up for relapse before treatment can take hold.
This guide walks through the five levels of care most clients move through: medical detox, residential treatment, partial hospitalization (PHP), intensive outpatient (IOP), and aftercare. It explains what each level is, who each one fits, and how a clinical team decides where to start.
Most people don't need to move through every level of care. The continuum is designed to flex to where you are. A clinical assessment matches you to the right level based on your current situation, not a fixed sequence.
| Level | Setting | Typical length of stay |
|---|---|---|
| Detox | Hospital or detox facility (24-hour) | 3 to 10 days |
| Residential | Live-in treatment facility | 30 to 90 days |
| PHP | Outpatient, live at home | 2 to 6 weeks |
| IOP | Outpatient, live at home | 8 to 12 weeks |
| Aftercare | Outpatient and community | Ongoing |
Medical detox is a short-term, supervised program that safely manages the physical withdrawal from substances. It is not addiction treatment in the psychological sense. It is the medical clearing of substances from the body so that the next phase of clinical care can be effective.
Who needs medical detox:
Who typically doesn't need medical detox:
Medical detox is generally not required for stimulants (cocaine, methamphetamine), cannabis, or mild or occasional alcohol use. Most clients in these categories go directly into PHP, IOP, or therapy.
Detox includes medical monitoring, medications to manage withdrawal safely, and stabilization before transition to the next level of care.
Coastwise is an outpatient program and does not provide detox on-site. When detox is clinically needed, we connect you with trusted detox partners in Los Angeles and the South Bay, and pick up your care in our PHP or IOP as soon as you're medically cleared.
Residential treatment is a 24-hour live-in program where clients live at the treatment facility for the duration of care. It provides continuous medical and clinical supervision, complete separation from the home environment, and an immersive daily schedule.
When residential is the right choice:
Residential is clinically indicated when a client needs 24-hour medical or psychiatric monitoring, has severe withdrawal risk, lives in an unsafe or actively triggering home environment, has acute psychiatric instability, or has tried outpatient treatment multiple times without stabilizing.
When residential is not necessary:
Residential is not a prerequisite for outpatient care. Many people go directly into PHP or IOP without ever attending residential. The cultural assumption that you have to "go away" to get better delays treatment for many clients who would do well in outpatient. Research on long-term outcomes consistently shows that what predicts recovery is engagement, evidence-based modalities, and continuity of care, not whether the client lived at a facility.
Coastwise specializes in outpatient care. When residential is the right call, we coordinate with trusted residential partners in the Los Angeles area.
PHP is the most intensive outpatient level of care. Clients attend substantial daily programming while living at home or in sober living, returning each evening.
Programming includes daily group therapy, individual therapy, psychiatric care, case management, evidence-based modalities (CBT, DBT, EMDR, trauma-informed therapy), and holistic programming including mindfulness, yoga, and somatic work. Call us to learn about our current PHP schedule: (424) 536-3002.
Who PHP fits:
For a full comparison of PHP and IOP, see our companion post: PHP vs. IOP: Which Level of Care Is Right for You?
IOP is structured outpatient programming designed to deliver clinical support while the client continues working, attending school, or caring for family. It is often used as a standalone program and is also the natural next step after PHP.
IOP includes individual therapy sessions, group therapy in small settings, regular psychiatric appointments, case management, and the same evidence-based modalities used in PHP. Call us to learn about our current IOP schedule and availability: (424) 536-3002.
Who IOP fits:
Aftercare is the long-term phase of recovery that follows more intensive treatment. It is not a separate program clients move through and complete. It is the ongoing infrastructure that keeps recovery in place after the initial clinical phase ends.
At Coastwise, aftercare includes:
Aftercare is often the difference between short-term abstinence and lasting recovery. Most clinical research on long-term substance use disorder outcomes points to continuity of care, not initial program intensity, as the strongest predictor of sustained sobriety.
Five questions help clarify the decision before your clinical assessment:
This decision is rarely one to make alone. A clinical assessment, which Coastwise offers free and confidentially, identifies what level of care fits your current situation. If detox or residential is the right call, we will tell you that and help coordinate the referral.
Yes. Detox, residential, PHP, IOP, and aftercare are all covered by most major insurance plans when clinical needs support that level of care. Outpatient programs (PHP and IOP) are generally covered at a high percentage by PPO plans. Our admissions team verifies your benefits at no cost. Call (424) 536-3002 or verify your insurance online.
If you're trying to figure out which level of care is right for you or for someone you love, a free phone consultation with our admissions team is the fastest path to clarity. The screening takes 15 to 20 minutes and gives you a direct answer. If your situation calls for a level of care we don't provide on-site, we will coordinate that referral honestly and help you transition into our outpatient program afterward.
Call (424) 536-3002 or request a consultation online. Monday through Saturday, 9:00 AM to 8:00 PM.
Coastwise serves Long Beach, San Pedro, Torrance, and the greater South Bay from our facility at 1366 W 7th Street, San Pedro, CA.
It depends on the substance, the amount, the duration of use, and your medical history. Alcohol, benzodiazepines, and high-dose opioids often require medical detox first because withdrawal can be medically dangerous. Stimulants, cannabis, and mild or occasional alcohol use typically do not require medical detox. A clinical assessment determines whether detox is needed.
Alcohol (heavy or prolonged daily use), benzodiazepines (Xanax, Valium, Klonopin, Ativan), and opioids (heroin, fentanyl, high-dose prescription opioids) most often require medical detox. Alcohol and benzodiazepine withdrawal can cause seizures and is medically dangerous without supervision. Opioid withdrawal is severe enough that medical detox usually makes the difference between someone staying in treatment and going back to use for relief.
No. Residential treatment is not a prerequisite for outpatient care. Many people begin recovery directly in PHP or IOP and never need residential. A clinical assessment determines whether outpatient is appropriate as a starting point based on your withdrawal risk, home environment, and co-occurring conditions.
For clients who are appropriate for outpatient level of care, research consistently shows comparable long-term outcomes to residential treatment. What predicts long-term recovery is engagement in treatment, evidence-based modalities, continuity of care, and aftercare. The setting matters less than the clinical fit.
Residential is clinically indicated when a client needs 24-hour monitoring, has severe withdrawal risk, lives in an unsafe home environment, has acute psychiatric instability, or has tried outpatient multiple times without stabilizing. It is not a default requirement and is not needed for most people starting recovery.
