What is a Partial Hospitalization Program (PHP) in California?

A PHP is a structured day treatment program that provides intensive clinical care, including therapy and medical support, while allowing individuals to return home or to a supportive living environment each evening. It serves as an intermediate level of care between inpatient and outpatient settings.

What services are included in a PHP?

PHP typically includes individual therapy, group counseling, case management, medical monitoring, relapse prevention planning, and life‑skills support delivered by licensed clinicians to address addiction and any co‑occurring mental health conditions.

Who is a PHP appropriate for?

A PHP is appropriate for individuals who need intensive structured support and clinical oversight but do not require 24‑hour inpatient care, such as those transitioning from detox or needing more support than standard outpatient treatment.

How does PHP support recovery progression?

PHP helps individuals build coping skills, establish routines, stabilize health, and prepare for lower levels of care, promoting smoother transitions to outpatient therapy or community‑based support after program completion.

When someone is battling addiction or a mental health disorder, the question of “what’s next?” becomes both urgent and overwhelming. Often, people picture either full inpatient care—where a person stays in a facility 24/7—or a much lighter form of outpatient support. But there’s a crucial middle ground that offers intensive treatment without requiring an overnight stay: the Partial Hospitalization Program, or PHP.

If you or a loved one is navigating the complexity of substance abuse or co-occurring disorders, understanding what a partial hospitalization program in California truly looks like can offer clarity, direction, and perhaps even hope.

What is a Partial Hospitalization Program (PHP)?

A partial hospitalization program (PHP) is a structured, intensive level of care designed for individuals who need more support than what a typical intensive outpatient program (IOP) offers but do not require 24/7 supervision like inpatient treatment.

In essence, PHP is a step-down from inpatient care or a step-up from outpatient services. It offers several hours of daily therapy and support—usually five to seven days a week—without requiring the patient to stay overnight.

Unlike residential treatment, PHP allows patients to return home at the end of the day, which makes it a highly practical alternative for many Californians trying to balance recovery with everyday life responsibilities.

What a Typical Day in a PHP Looks Like

Patients in a partial hospitalization program usually participate in treatment for about six to eight hours a day, five days a week. A day in a partial hospitalization program often includes:

Individual therapy: One-on-one sessions that focus on personal challenges, goals, and the recovery process.
Group therapy sessions: These offer peer support and help you develop healthy coping skills.
Family therapy sessions: Involving family members in the healing process can foster accountability, communication, and trust. It can also increase the amount of support you have at home.
Medication management: For those managing a mental health disorder like depression or anxiety, regular psychiatric check-ins ensure medications are working effectively.
Skill development workshops: These focus on stress regulation, communication, emotion processing, and relapse prevention strategies.
Dialectical Behavioral Therapy (DBT): A highly effective, evidence-based therapy for treating co-occurring disorders, including emotional dysregulation and substance abuse. Often used during dual diagnosis programs.

Personalized Care: The Core of PHP

No two people experience addiction or mental health in the same way. That’s why a hallmark of California’s best PHPs is the emphasis on individualized treatment plans. These plans are designed after comprehensive assessments by licensed clinicians, social workers, and psychiatrists, who evaluate the patient’s symptoms, medical history, substance use background, and life circumstances.

The result? A personalized care plan that addresses both the root causes and the symptoms of the condition, tailored to the unique needs of the patient.

Who is PHP For?

A partial hospitalization program is an appropriate level of care for:

Individuals leaving an inpatient program who still need intensive treatment.
People experiencing acute mental health symptoms but who are stable enough to avoid an inpatient stay.
Patients who struggle with co-occurring disorders such as substance abuse and depression, anxiety, or PTSD.
Adults in need of a structured environment to regain functionality while staying connected to their daily lives.

In short, PHPs offer a safe and supportive environment for people who require more than once-weekly therapy but don’t need round-the-clock care.

PHPs in California: What Sets Them Apart

California—especially in Southern California, like Sherman Oaks—is a hub for progressive, integrated care. From Los Angeles to San Diego, PHPs are often located near beaches, mountains, or nature retreats, helping foster a welcoming environment conducive to healing.

Moreover, the state is home to a high concentration of dual-diagnosis experts and trauma-informed care facilities. This is critical when treating co-occurring disorders, where behavioral health and addiction intersect.

In California, PHPs often offer special services like:

Access to holistic therapies like yoga, meditation, or art therapy.
A broader focus on life skills and transition planning.
Multidisciplinary teams are composed of psychiatrists, social workers, therapists, case managers, and peer support specialists.

Why Choose PHP Over Other Options?

While inpatient treatment might feel like the safest choice, it can be disruptive to your daily life and expensive. At the other end, intensive outpatient programs may not provide enough structure for those in early recovery.

A partial hospitalization program (PHP) bridges that gap. It allows individuals to maintain a level of independence while receiving intensive care. This model also supports a step-down approach, where patients can gradually move to an intensive outpatient setting, then outpatient care, and eventually full independence, without abrupt transitions that make relapse a risk.

The Numbers: What the Data Shows

According to the National Institute on Drug Abuse (NIDA), 40-60% of individuals recovering from substance use disorder will relapse at some point.[1] PHPs offer relapse-prevention tools early in recovery when the risk is highest.

The Substance Abuse and Mental Health Services Administration (SAMHSA) reports that approximately 17 million adults in the U.S. experienced both a substance use disorder and a mental health disorder in 2023.[2] Programs that offer integrated treatment, like PHPs, have higher success rates than those treating these conditions separately.

California consistently ranks among the top states for access to behavioral health services, with an increasing number of facilities offering adult partial hospitalization programs designed for specific populations (e.g., veterans, LGBTQ+, adolescents, and trauma survivors).

Transitioning Back to Daily Life

One of the core strengths of PHP programs is how they prepare patients to reintegrate into everyday life. By providing real-world coping tools and peer support while allowing individuals to return home at night, these programs foster autonomy and accountability from the very beginning.

Many PHPs also include aftercare planning, connecting patients to alumni groups, outpatient therapists, and community-based recovery support systems.

Frequently Asked Questions (FAQs)

1. How long does someone typically stay in a partial hospitalization program?

While program lengths vary depending on individual needs, most PHPs last between two to six weeks. The exact duration is determined by ongoing clinical assessments and how well the person is responding to treatment. Some patients may transition into an Intensive Outpatient Program (IOP) afterward for continued support.

2. Can someone work or attend school while enrolled in a PHP?

Due to the time commitment—often 6+ hours a day, five days a week—most participants are not able to work or attend school full-time during PHP. However, many facilities offer flexible scheduling or evening programming, and short-term leave from work or school may be advisable during this phase of treatment.

3. Does insurance cover partial hospitalization programs?

Yes, many private insurance plans and Medicaid options in California do cover PHPs under behavioral health services. However, coverage varies by provider and plan. It’s recommended to contact your insurance company or have the treatment center verify benefits and handle pre-authorization if needed.

4. Are meals or transportation included in PHPs?

Some PHPs include meals during treatment hours, especially those located at medical centers or residential-style campuses. Transportation is not typically included, but some programs offer shuttle services or help coordinate rides for patients with limited mobility or resources.

5. What qualifications do the PHP staff typically have?

Staff in a PHP usually include licensed clinical social workers (LCSWs), psychologists, psychiatrists, nurses, and certified addiction counselors. Many programs also include peer support specialists and case managers. All staff are trained in trauma-informed care and substance use treatment.

6. Can a PHP accommodate individuals with physical disabilities or chronic medical conditions?

Many modern PHPs in California are ADA-compliant and designed to support patients with physical limitations. If someone has a chronic condition like diabetes or epilepsy, medical staff can often coordinate care in tandem with behavioral health treatment, though this should be discussed during the intake process.
