A PHP, or partial hospitalization program, is a structured mental health treatment program where you attend therapy and psychiatric services during the day, typically five to seven days a week, then go home in the evening. It sits between inpatient hospitalization and traditional outpatient therapy on the spectrum of mental health care, offering intensive support without requiring an overnight stay.
Most programs last two to four weeks and require at least 20 hours of treatment per week. PHPs are commonly used as a step-down after an inpatient psychiatric stay, or as an alternative to hospitalization for people who need more support than a weekly therapy appointment but don’t require around-the-clock supervision.
What a Typical Day Looks Like
A PHP functions like a full or near-full day of treatment. You arrive in the morning and spend the day rotating through different types of therapy sessions, skill-building workshops, and check-ins with mental health professionals. Afternoons generally include additional individual, group, or family therapy, giving you time to work through challenges and practice new coping strategies before heading home for the evening.
The minimum standard is at least 20 hours of therapeutic contact per week, spread across at least four days, with a minimum of three hours on each of those days. In practice, many programs run five to seven days a week with sessions lasting six or more hours per day. This intensity is what separates a PHP from less structured outpatient options.
Types of Therapy Used in PHPs
PHPs draw on several evidence-based approaches, tailored to what each person needs:
- Cognitive behavioral therapy (CBT) helps you identify and change negative thought patterns. It’s widely used for depression, anxiety, and substance use disorders.
- Dialectical behavior therapy (DBT) focuses on emotional regulation, distress tolerance, and mindfulness. It was originally developed for borderline personality disorder but is now used for a range of conditions involving intense emotions or self-harm.
- Group therapy sessions create a space to share experiences, learn from others going through similar struggles, and practice communication skills. Common topics include stress management and relapse prevention.
- Family therapy brings family members into the treatment process to improve communication, resolve conflicts, and build a stronger support system at home.
- Medication management involves psychiatric professionals monitoring and adjusting medications as part of the overall treatment plan.
Some programs also incorporate acceptance and commitment therapy (ACT), occupational therapy, and educational sessions about your specific condition. The mix of therapies can vary from program to program, but the common thread is a structured, multi-layered approach rather than relying on a single type of treatment.
Who Works With You in a PHP
PHPs are staffed by a multidisciplinary team. You’ll typically work with psychiatrists or other physicians, psychologists, licensed clinical social workers, psychiatric nurses, and sometimes certified substance use counselors. This team collaborates on your treatment plan and adjusts it as you progress. The presence of prescribing clinicians is one reason PHPs can offer medication management alongside therapy, something most standard outpatient settings can’t do as closely.
How PHP Compares to IOP
The level of care just below a PHP is an intensive outpatient program, or IOP. The two are easy to confuse because both let you live at home, but they differ in meaningful ways.
PHPs are more intensive. You attend five to seven days a week for several hours each day, and the treatment environment is highly structured with close psychiatric oversight. IOPs typically meet three to five days a week for fewer hours and run over a longer period, often 8 to 12 weeks. The focus in an IOP leans more toward building coping skills, preventing relapse, and strengthening support networks, while a PHP provides the kind of comprehensive psychiatric care and crisis stabilization that someone recently discharged from inpatient care might need.
The tradeoff is flexibility. IOPs are designed to let you keep going to work or school. PHPs require a bigger time commitment, which can make them harder to fit around daily responsibilities. Many people move through these levels in sequence: inpatient care first, then PHP, then IOP, then traditional outpatient therapy. Others enter directly at the PHP level if their symptoms are severe but don’t require hospitalization.
How Long a PHP Lasts
The standard duration is two to four weeks, though the exact length depends on your progress, the severity of your condition, and your treatment team’s assessment. Some people stabilize quickly and step down to an IOP within two weeks. Others benefit from the full four weeks or occasionally longer. The goal is always to transition you to a less intensive level of care as your symptoms become more manageable.
Insurance Coverage for PHPs
Medicare Part B covers partial hospitalization services when a doctor or qualified mental health professional certifies that you would otherwise need inpatient treatment. The program must provide at least 20 hours of therapeutic services per week, and both the provider and the program must accept Medicare assignment. After meeting the Part B deductible, you pay coinsurance for each day of services.
Medicare covers the core treatment components, including group psychotherapy, individual therapy, occupational therapy related to mental health, patient education, and caregiver training. It does not cover meals, transportation, social support groups (as distinct from clinical group therapy), or job skills training that isn’t part of your mental health plan.
Most private insurance plans also cover PHPs, though the specifics vary by carrier and plan. Coverage typically requires a pre-authorization showing that the level of care is medically necessary. If you’re considering a PHP, calling your insurance provider before enrollment can clarify your out-of-pocket costs and any limits on the number of covered days.
