A PHP is the most intensive level of outpatient treatment. At Changes, it runs several hours a day, five days a week, with evenings at home. It gives you daily clinical structure without the overnight stay of residential treatment.
PHP at Changes involves several hours of treatment a day, five days a week, depending on your personalized plan. It is more intensive than IOP, which runs 9 to 15 hours a week.
PHP is the more intensive of the two. It runs several hours a day, five days a week, while IOP runs 9 to 15 hours a week across fewer days. Many clients step down from PHP to IOP as they stabilize.
Most clients attend PHP for several weeks before stepping down to a lower level of care. The exact length depends on your progress and clinical needs, which your team reviews with you throughout.
Yes. PHP is a daytime program, so you attend treatment during the day and return home each evening. That structure lets you practice new skills in your own environment while getting intensive daily support.
Some clients come to PHP after detox or residential care, and some start at the PHP level directly. Changes does not provide detox or residential treatment on-site, but we coordinate referrals with licensed partners and bring you into PHP once you are stable.
Most major insurance plans cover PHP with prior authorization, since it is a recognized step in the continuum of care. Changes works with most major providers and verifies your benefits in about 15 minutes, free and confidential. Private-pay options are available if needed.
PHP is the right level of care for adults who need daily clinical structure but do not require 24-hour residential treatment. It sits one step above IOP in intensity, and it fits people whose symptoms or recovery needs call for consistent, full-day support while they live at home.
Most people who enter our PHP fall into a few groups. Some are stepping down from residential treatment or a detox referral and need intensive daily support before moving to a lower level of care. Others are coming from a crisis point or finding that weekly therapy, or even IOP, is not enough to stay stable. Others are managing a substance use disorder alongside a co-occurring condition such as depression, anxiety, or trauma that needs daily attention.
A clinical assessment determines whether PHP is the right starting point. If your needs are better matched by a different level of care, we will tell you and help you get there.
PHP at Changes involves several hours of treatment a day, five days a week, with evenings spent at home. The schedule is structured and consistent, which is what gives PHP its clinical strength: daily contact lets your team monitor progress closely and adjust care quickly.
Treatment starts with a clinical assessment. A licensed clinician reviews your history, current symptoms, and any co-occurring conditions, then builds an individualized plan that sets your daily focus and a realistic path through the program. Because the program runs five days a week, that plan can move at the pace your recovery actually needs rather than waiting week to week.
A typical day combines group therapy, individual therapy, and skills-based sessions. Group work builds peer support and accountability. Individual therapy gives you focused time with a clinician on the specific issues driving substance use or destabilizing your mental health. Skills sessions cover the practical work of recovery: managing triggers, regulating emotions, and building routines that hold once the program ends.
Because you return home each evening, PHP lets you practice new skills in your real environment and bring what happens back into the next day’s sessions. Most people attend PHP for several weeks before stepping down to a lower level of care, usually IOP, as they stabilize.
Our PHP uses evidence-based, individualized therapies, including Cognitive Behavioral Therapy, Dialectical Behavior Therapy, Motivational Interviewing, trauma-informed care, and relapse-prevention strategies.
Cognitive Behavioral Therapy (CBT) anchors the clinical work. It helps you identify the thoughts and patterns that drive substance use and mental health symptoms, then build healthier responses you can use every day.
Dialectical Behavior Therapy (DBT) teaches emotional regulation, distress tolerance, mindfulness, and interpersonal skills. At the PHP level, where clients often arrive with intense symptoms, these skills do a lot of the daily stabilizing work.
Motivational Interviewing strengthens your own commitment to change, which matters most in the early, less-settled stage of recovery that PHP is often built to address.
Trauma-informed care runs underneath all of it. Our clinicians account for how past trauma shapes current behavior, so treatment supports stability rather than setting it back. Relapse-prevention work carries through the whole program and into your step-down plan.
PHP is the most intensive outpatient level Changes offers, and most clients move through it as one step in a continuum. If you need medical detox or residential care first, we coordinate that through licensed referral partners, then bring you into PHP once you are stable. As you progress, you typically step down from PHP to our Intensive Outpatient Program, and later to continuing care.
Changes Treatment Center works with most major insurance providers, and we verify benefits on any plan in about 15 minutes. Most commercial plans cover PHP with prior authorization, since it is a recognized step in the continuum of care, though exact coverage and out-of-pocket cost depend on your specific plan.
The fastest way to know what you would pay is to let us check for you. Verification is free, carries no obligation, and we handle the insurer directly. If you do not have coverage that works, we offer private-pay options and will talk through the most realistic path on a confidential call.
PHP and IOP are both outpatient, so you live at home in both. The difference is intensity. PHP is the right level when you need full, structured days of clinical support five days a week. IOP is the right level once you are stable enough to return to work or family responsibilities and need fewer hours each week.

Orange County has been hit hard by addiction. The county recorded an estimated 490 accidental overdose deaths in 2023, and its opioid overdose death rate nearly tripled between 2017 and 2021, according to the Orange County Health Care Agency. The agency notes that cities along the coastal and southern parts of the county, Costa Mesa among them, tend to see higher rates of drug- and alcohol-related hospitalizations than inland areas. County figures for 2024 show overdose deaths beginning to fall, which local health officials link to wider access to treatment and naloxone.
For someone who needs intensive daily support, a local PHP matters more than it might at a lower level of care, because you are on-site five days a week. Changes Treatment Center is at 2787 Bristol Street in Costa Mesa, serving adults across Orange County. Insurance verification takes about 15 minutes, and most clients can begin within a few days.
