Partial Hospitalization Program (PHP) at Milestone Treatment Center

Recovery is a journey of steps, and finding the right level of care is critical for long-term success. For many individuals, a standard outpatient visit isn’t enough, but 24/7 residential care isn’t necessary. This is where a Partial Hospitalization Program (PHP) bridges the gap. At Milestone Treatment Center, serving Merchantville, NJ, and Virginia Beach, VA, our PHP offers highly structured, full-day treatment that allows you or your loved one to live at home.

What is a Partial Hospitalization Program (PHP)?

A Partial Hospitalization Program (often called “Day Treatment”) is the highest level of outpatient care available. It provides the intensive medical and therapeutic structure of an inpatient rehab facility but you or your loved one can maintain independence and privacy by sleeping in their own home or a sober living environment.

Unlike an Intensive Outpatient Program (IOP), which typically meets for a few hours a day, PHP is a full-time commitment. Folks attend treatment 5 to 6 days a week, for roughly 6 hours a day.

At Milestone Treatment Center, our PHP is designed to stabilize individuals immediately following detox or for those whose needs are too complex for standard outpatient care.

Who Benefits from PHP?

Partial Hospitalization is ideal for individuals who require robust support but do not need 24-hour medical supervision. It is particularly effective for those who:

  • Have recently completed a medical detox and need stabilization.
  • Are stepping down from residential inpatient care but aren’t ready for less frequent therapy.
  • Struggle with co-occurring mental health disorders (dual diagnosis) requiring daily monitoring.
  • Have a supportive home environment free from triggers.

Measurable Outcomes: Milestone’s Success

Does intensive day treatment work? Our data says yes. By immersing you or your loved one in a therapeutic environment all day while practicing skills at home at night, we see significant improvements. Between Dec 2024 and May 2025, Milestone alumni reported:

  • 18% overall decrease in depression symptoms.
  • 17% decrease in anxiety symptoms.
  • 47% decrease in substance cravings.
  • 16% decrease in perceived stress levels.

National Research: Why PHP is the “Gold Standard”

Milestone’s PHP fits squarely within a research-backed model. Studies across the United States consistently find that most participants experience meaningful clinical improvement by discharge.

1. Proven Symptom Reduction

Across diagnoses like major depression and bipolar disorder, studies report symptom reduction rates in roughly 65–75% of PHP patients, with anxiety disorders also showing strong response to structured day treatment.

Furthermore, gains in functioning and mental health made during PHP were generally maintained after discharge, indicating durable benefit beyond the program itself. Patient-reported outcome data also shows that, on average, participants rate themselves as “much improved” or “quite a bit helped,” with program satisfaction typically high.

2. Reducing Relapse and Hospitalization

Because PHPs aim to prevent or shorten inpatient stays, hospitalization rates are a key outcome. In one large study, effective PHP care cut the proportion of enrolled patients requiring inpatient hospitalization from 16.5% of discharges down to 8.9%. Another quality‑improvement report found that in a single year, a PHP admitted 95 of 169 referrals (56%) and tracked ongoing decreases in inpatient utilization among those completing treatment.

For substance use specifically, an alcohol‑focused PHP study reported that fewer than one‑third of patients relapsed to alcohol use at one‑month follow‑up, despite high severity in their day-to-day lives.

3. Closing the Gap in Care

Partial hospitalization has become a standard level of care across many hospital systems and behavioral health organizations. In fact, sector reports note that PHPs and IOPs were among the “bright spots” in behavioral health investment through 2023, reflecting increased demand for options that bridge the gap between weekly therapy and full residential care.

Frequently Asked Questions

How long does PHP last?

The length of stay varies by individual progress, but most folks participate in PHP for 2 to 4 weeks before stepping down to an Intensive Outpatient Program (IOP).

Can I go to work while in PHP?

Because PHP is a full-time commitment (typically 9am to 3pm), working during program hours is usually not possible. However, we can help coordinate FMLA paperwork for medical leave.

Does insurance cover PHP?

Yes, most private insurance providers cover Partial Hospitalization as a medical necessity. Our admissions team can verify your benefits for free.
