Partial Hospitalization Program

Residential-level clinical intensity without the overnight stay.

A partial hospitalization program, or PHP, is built for clients who need significant daily structure and support but are stable enough to spend evenings at home or in supportive housing. Across Odyssey Behavioral Healthcare’s treatment brands, PHP treats mental health conditions, substance use disorders, and eating disorders under organizational clinical standards set by Odyssey’s Clinical Quality Council.

Understanding PHP

What Is a Partial Hospitalization Program?

A partial hospitalization program is a structured, full-day treatment program that typically meets at least five days per week. Clients spend most of the day in clinical programming, then return home or to supportive housing in the evening.

PHP delivers many of the same clinical components as residential treatment, including individual therapy, group therapy, psychiatric care, and specialized programming, but without the overnight residential component. This makes it an effective option for clients who need intensive treatment while maintaining some connection to their home environment.

What to Expect in PHP

PHP is often used as a step down from residential treatment, allowing clients to maintain clinical intensity while beginning to reintegrate into daily life. It can also serve as a step up from intensive outpatient care for clients who need more structure, or as a direct entry point for clients whose needs require more than outpatient care but not 24-hour residential support.

For clients who need housing support during PHP, select programs offer residential housing options alongside programming. Lifeskills Behavioral Health offers transitional living, and STR Behavioral Health offers supportive housing, allowing clients to participate in full-day treatment while living in a structured, supportive environment.

A partial hospitalization program at Odyssey includes:

  • Full-day programming

    Clinical programming that typically runs five or more days per week

  • Individual and group therapy

    Core therapeutic work delivered daily

  • Psychiatric care

    Psychiatric evaluation and medication management as clinically appropriate

  • Specialized programming

    Treatment tailored to the client’s diagnosis and clinical needs

  • Evening flexibility

    Clients return home or to supportive housing in the evenings

  • Structured support

    A consistent daily schedule that reinforces stability and progress

Finding the Right Support

Who Is PHP For?

Odyssey’s admissions teams evaluate each client’s clinical situation to determine whether PHP is the right level of care, or whether another level would better serve their needs.

A partial hospitalization program is appropriate for clients who:

  • Need intensive, structured treatment but are stable enough to spend evenings outside a treatment facility

  • Are stepping down from residential or inpatient treatment

  • Require more support than outpatient care can provide but not 24-hour residential care

  • Benefit from full-day clinical structure while maintaining some connection to their home environment

Bridging the Treatment Gap

PHP as Part of the Continuum

PHP is often a step within a longer treatment journey. Many clients enter PHP as a step down from residential or inpatient treatment, then continue to intensive outpatient or virtual outpatient programming as they progress. For others, PHP is a step up from intensive outpatient care when their clinical needs call for more structure and support. And some clients enter PHP directly when their needs call for full-day structure without an overnight stay.

Odyssey’s full continuum of care allows clients to move through these levels within the same organization. Clinical information transfers, treatment planning stays consistent, and clients don’t have to start over with a new provider each time their level of care changes.

PHP vs Residential + Intensive Outpatient

Understanding where PHP fits in the continuum helps clarify whether it’s the right level of care.

Odyssey’s admissions teams help determine the level of care that best fits each client’s clinical situation, and clients can move between levels as their needs change.

Compared to residential treatment

PHP offers a comparable level of clinical intensity during the day but without the overnight stay. Clients in PHP are stable enough to spend evenings outside the treatment facility.

Compared to intensive outpatient (IOP)

PHP is more intensive than IOP, with full-day programming versus IOP’s several hours per week. PHP suits clients who need more structure than IOP can provide.

Frequently Asked Questions

What is a partial hospitalization program (PHP)?

A partial hospitalization program is a structured, full-day treatment program that typically meets five or more days per week.

What is the difference between PHP and residential treatment?
