The Partial Hospitalization Program in Winnetka at Fortify Wellness is the most structured level of care we offer without an overnight stay, built for adults and adolescents who need full clinical days but can recover at home each evening. The program treats substance use alongside depression, anxiety, bipolar disorder, and trauma. Call (818) 918-9564 to speak with admissions today.
A partial hospitalization program, or PHP, is day treatment: you spend most of the day in structured clinical care, then return home each evening rather than staying overnight. It is the highest level of care below residential treatment, and it exists for a specific moment in recovery. PHP is the right level when symptoms or cravings are too intense for a few outpatient hours a week to hold, but a locked residential bed is not necessary. People most often enter PHP in one of two ways: stepping down from inpatient or detox and needing to keep daily structure while they stabilize, or stepping up from outpatient care when life has become unmanageable and weekly therapy is no longer enough. Because you go home each evening, PHP also lets you practice new coping skills in the same environment where you will use them, which is part of why the level works.
A PHP day at Fortify Wellness is built around clinical hours rather than a single appointment. The day combines individual therapy, multiple group sessions, and psychiatric and medical oversight, with the specific mix set by your assessment. Cognitive behavioral therapy anchors the clinical work, and group sessions cover relapse prevention, processing, and skill-building so you are not working through recovery alone. Medication management runs alongside the therapy for anyone with a co-occurring condition, so depression, anxiety, or trauma are treated in step with the substance use rather than left for later. Because PHP fills most of the day, it is the level where the heaviest clinical work happens before a person steps down to less intensive care.
PHP is rarely where treatment ends; it is where the most intensive outpatient work begins, before a planned step down. Most people move from PHP into an intensive outpatient program once they stabilize, then into standard outpatient care as they return fully to work, school, or family life. That continuum matters because recovery is not a single event, and the level of support should match where a person actually is week to week. The same clinical team carries you through each step, so moving from PHP to a lighter level does not mean starting over with new providers or repeating your history to strangers. Your team adjusts the level based on clinical progress, not a fixed calendar.
For the right person, partial hospitalization is as effective as inpatient care, and the research supporting that goes back decades. PHP sits at Level 2.5 on the American Society of Addiction Medicine continuum, the most intensive outpatient level, one step below residential. A widely cited review of intensive outpatient and day-treatment programs found that randomized and quasi-experimental studies consistently reported reductions in substance use and outcomes comparable to inpatient or residential care for appropriately selected patients. The phrase that matters there is appropriately selected: PHP is not right for everyone, which is why the assessment comes first. For someone who is medically stable and has a safe place to sleep, a full day of structured treatment can do the same clinical work as a residential stay while keeping their job, their home, and their family connections intact. For someone whose withdrawal or symptoms need overnight monitoring, it cannot, and the honest answer in that case is residential care first.
The question most people weigh before entering PHP is whether they need a residential bed instead. The difference comes down to overnight supervision and medical acuity. The table below lays out how the two compare.
If you can stay safe and supported at home overnight, PHP gives you the clinical intensity of a full treatment day without leaving your life entirely. If symptoms or withdrawal need monitoring around the clock, residential care is the safer starting point, and our admissions team will say so directly during your assessment rather than place you in the wrong level. For anyone who needs medically supervised detox first, we coordinate that through trusted licensed providers before PHP begins.
The first day starts with a clinical assessment rather than a group room. A licensed clinician reviews your history, your current use, any co-occurring conditions, and your medical needs, and that conversation sets your treatment plan and confirms PHP is the right level. From there, a typical PHP week is built around full clinical days, several days a week, made up of a rotating mix of individual therapy, process and skills groups, and time with psychiatric and medical staff where it is needed. Early on, much of the work is stabilization: getting cravings, sleep, and any withdrawal aftermath under control so the deeper therapeutic work can land. As the days go on, the focus shifts toward the patterns underneath the substance use and the practical skills for handling them once treatment ends. Families are brought in where that is appropriate, because the home you return to each evening is part of the recovery, not separate from it. None of this runs on a fixed countdown. How long you stay in PHP, and when you step down to an intensive outpatient program, is decided by your clinical team based on progress, not a preset number of days.
Partial hospitalization is a covered level of care under most commercial insurance plans, usually with prior authorization because it is a higher-intensity program. Fortify Wellness holds California DHCS certification (Cert 191603AP), and our admissions team confirms what your specific plan approves for day treatment, including how authorization and continued-stay reviews work, before you commit to a start date. The point is that you walk in already knowing what is covered.
Getting in is straightforward. Reach us by phone or the secure form and admissions will hear out your situation, then a confidential clinical assessment determines whether PHP is the right entry point or whether you should step up or down a level. Once that is settled, you begin, with your benefits and any out-of-pocket cost confirmed in advance. Benefit checks cost nothing, and for anyone without coverage, our team lays out private-pay paths instead of closing the door.
Winnetka sits in the heart of the west San Fernando Valley, bordered by Canoga Park, Reseda, and Northridge, with Los Angeles Pierce College drawing a large student and young-adult population into the area. For people living here, a full-day program only works if it is close enough to attend every day without a long commute eating into the hours treatment requires. Fortify Wellness is a short drive north in Granada Hills, which keeps a daily PHP schedule realistic for Winnetka residents rather than something that falls apart after the first week. We work with people across Winnetka, Canoga Park, Reseda, and the surrounding west Valley communities, where demand for accessible day treatment remains high even as Los Angeles County overdose deaths have begun to fall.
The county data explains why a high-intensity level like PHP still matters even as the overall picture improves. Los Angeles County recorded 2,438 drug-related overdose and poisoning deaths in 2024, down 22 percent from 3,137 the year before, the largest single-year drop in county history, according to the Los Angeles County Department of Public Health. Fentanyl was still involved in 52 percent of those deaths. That combination of real progress alongside a drug supply still dominated by fentanyl is exactly the situation PHP is built for: people whose use has reached a dangerous point need structured, daily clinical care quickly, and a day program delivers that intensity without waiting for a residential bed to open.
PHP is a full-day program, the most time-intensive level of care below residential. You attend structured clinical hours during the day and return home each evening. Your assessment sets the exact schedule for your plan.
No. Inpatient and residential treatment include overnight stays with 24-hour supervision. PHP gives you a full day of treatment and then you go home each evening, which makes it a step down from residential care.
Sometimes. If you need medically supervised detox first, we coordinate that through trusted licensed providers before PHP begins, then bring you into the day program once you are stable.
Yes. We treat both adults and adolescents, and the program addresses substance use together with co-occurring conditions like depression, anxiety, and trauma.
Most people step down from PHP to an intensive outpatient program, then to standard outpatient care, with the same clinical team carrying through each level. Your team adjusts the pace based on your progress.
Most commercial plans cover medically necessary PHP, usually with prior authorization since it is a higher level of care. We confirm exactly what your plan approves and what it will cost before your start date, so nothing about coverage is a surprise.
For appropriately selected patients, research has long found day treatment produces outcomes comparable to inpatient or residential care. It works best for people who are medically stable and have a safe place to stay overnight; a clinical assessment confirms whether it fits your situation.
Partial hospitalization is Level 2.5 on the American Society of Addiction Medicine continuum, the most intensive outpatient level, one step below residential treatment and one step above an intensive outpatient program.

A full treatment day asks a lot, and it is easier to say yes to when the program is a short drive and the clinical team stays the same from one level to the next. Call (818) 918-9564 or send the secure insurance form, and admissions will tell you plainly whether PHP fits where you are right now, or whether another level is the better place to start.
