A partial hospitalization program, or PHP, is a level of addiction treatment that provides clinical care for most of the day, most days of the week, without requiring the person to stay overnight. It is the most intensive form of outpatient treatment, sitting just below residential care in the continuum. A person in the program spends the day in structured treatment and returns home or to sober living at night.
This level exists for people who need a high level of daily clinical support but do not require 24-hour supervision. That includes someone who has finished residential treatment and is not yet ready for a lighter schedule, and someone whose situation is serious enough to need daily care but stable enough to spend nights outside a facility. The full-day structure delivers the intensity of inpatient treatment during the hours it matters most, while allowing the person to begin practicing recovery in their own environment each evening.

PHP in Los Angeles is the right level of care for adults who need daily, structured clinical treatment but do not require an overnight stay. It fits a few clear situations.
The common thread is a need for intensive daily treatment paired with enough stability to spend nights outside a facility. PHP is not the right level for someone who still needs medical detox or 24-hour supervision, and it is more than someone with a mild disorder and strong support may need. The clinical assessment places a person at the level that matches their situation.

The program at Simonds runs for most of the day, several days a week, with a full schedule of clinical programming that mirrors the intensity of residential treatment during daytime hours. A typical day combines group therapy, individual counseling, skill-building, and relapse-prevention work, with medical and psychiatric support available throughout.
Each person begins with a clinical assessment that sets the schedule, the expected length of the program, and the therapies involved. Treatment draws on cognitive behavioral therapy, dialectical behavior therapy, group process work, family involvement where it helps, and medication-assisted treatment when it fits the plan. Because it is delivered on the same campus as detox, residential, and IOP care, a person can move up if they need more support or step down to IOP as they stabilize, without leaving the program. For people who need housing during this phase, the program pairs with sober living, so the daytime structure combines with a substance-free place to spend evenings.

PHP sits between residential treatment above it and intensive outpatient below it, and its main role is as a bridge. Recovery usually moves from the most intensive care down through progressively lighter levels, and PHP is the stage where a person keeps the daily structure of inpatient treatment while beginning to live outside a 24-hour facility.
This placement is what makes the level valuable. A person leaving residential care is often not ready to drop straight to a few sessions a week, and moving down too fast is a common point of relapse. A day program closes that gap. It maintains daily clinical contact during the vulnerable weeks after inpatient care, then hands off to IOP as the person stabilizes and takes on more independence. Because every level is delivered on the same campus, the transitions happen within one program rather than through referrals to new providers.
The program at Simonds treats the full range of substance use disorders on an intensive daily schedule. This includes alcohol addiction, opioid addiction including fentanyl and heroin, prescription opioid dependence, stimulant addiction including methamphetamine and cocaine, benzodiazepine dependence, and polysubstance use. It is also well suited to people with a co-occurring mental health condition, because the daily schedule allows both the addiction and the mental health condition to be treated together with real clinical intensity.
The daily structure is what makes this level effective for more complex cases. Conditions such as depression, anxiety, PTSD, and trauma often sit underneath a substance use disorder, and the near-daily contact of PHP gives the clinical team the time to address both at once, rather than treating the addiction alone and leaving the underlying condition for later.

The need for intensive treatment across Los Angeles County is significant. The Los Angeles County Department of Public Health reported that drug-related overdose deaths fell 22 percent between 2023 and 2024, from 3,137 to 2,438, with fentanyl-related deaths down 37 percent, though fentanyl was still involved in 52 percent of accidental overdose deaths in 2024. For people leaving residential care, a strong day program is often what carries recovery through the weeks when it is most fragile.
Simonds is in-network with TriWest and TRICARE and works with most major insurance carriers on an out-of-network basis, and we verify benefits in about 15 minutes. We do not accept Medicaid, Medicare, or Medi-Cal. Most commercial plans cover partial hospitalization with prior authorization, and the admissions team confirms what a plan covers before treatment begins, so the cost is clear before care starts.

PHP runs for most of the day, several days a week, with the exact schedule set during the clinical assessment. It is the most intensive outpatient level, close to the daily commitment of residential treatment but without the overnight stay.
Residential treatment includes 24-hour care with overnight stays at the facility. PHP delivers a similar intensity of daytime clinical treatment but the person returns home or to sober living each evening. PHP is often the step down from residential care.
PHP is more intensive, running most of the day, most days of the week. IOP is lighter, running a few hours a few days a week. Many people step down from PHP to IOP as they stabilize, and both are available at Simonds.
Yes. PHP pairs well with sober living, since the program provides daytime structure and sober living provides a substance-free place to spend evenings. Simonds can coordinate both together.
Most commercial plans cover partial hospitalization with prior authorization. Simonds is in-network with TriWest and TRICARE and works with most major carriers out-of-network, and benefits are verified in about 15 minutes.
It depends on the substance and level of dependence. Someone with a significant physical dependence usually completes medical detox first, while someone stepping down from residential care moves directly into PHP. The clinical assessment determines the right starting point.
