Outpatient addiction treatment in New Hampshire operates at three distinct levels: partial hospitalization (PHP), intensive outpatient (IOP), and standard outpatient. Each provides a different intensity of care, and the right choice depends on your clinical needs, not a guess. This guide explains how each level works, who they serve, and how clinical teams determine which one fits.
What Is a Partial Hospitalization Program (PHP)?
A partial hospitalization program is the most intensive level of outpatient addiction treatment. You attend treatment during the day and return home each evening.
At Trailhead Treatment Center in Salem, NH, PHP runs 9:00 AM to 3:30 PM, five days per week. Each day includes a minimum of 5 clinical hours as required by New Hampshire regulations. The schedule includes:
- Individual therapy with your assigned therapist
- Group therapy sessions led by licensed clinicians
- Holistic programming (yoga, breathwork, meditation, sound therapy)
- Case management and resource coordination
- Lunch provided on-site
PHP is designed for people who need daily clinical structure but do not require 24-hour supervision. This includes people stepping down from inpatient or residential treatment, people whose symptoms require daily clinical contact, and people living with co-occurring substance use and mental health conditions.
Typical PHP duration: 20 to 30 days, adjusted based on clinical progress.
What Is an Intensive Outpatient Program (IOP)?
An intensive outpatient program provides structured treatment in shorter daily sessions, allowing you to maintain work, school, or family responsibilities during treatment.
IOP at Trailhead runs 9:00 AM to 12:30 PM, five days per week. Evening scheduling is being developed for adults who cannot attend daytime sessions. IOP includes group therapy, case management, and holistic programming.
IOP is appropriate for people stepping down from PHP with demonstrated progress, people entering treatment directly who meet IOP-level criteria based on clinical assessment, and working adults who need intensive care on a schedule that allows continued employment.
Typical IOP duration: 60 to 90 days.
What Is Standard Outpatient Treatment?
Standard outpatient treatment provides individual therapy sessions and medication management on a scheduled basis, typically one to three hours per week.
Outpatient treatment at Trailhead serves people stepping down from IOP who still benefit from regular clinical contact, and people maintaining long-term recovery through ongoing therapeutic support.
Outpatient is the least intensive level of care. It works when you have a stable home environment, a support network, and the ability to manage daily life while attending periodic sessions.
How Clinical Teams Determine Your Level of Care
You do not need to decide which level of care you need before calling. The admissions team determines this through validated clinical assessments during your first phone call.
At Trailhead, the assessment uses three instruments:
- ASAM (American Society of Addiction Medicine) criteria for substance use severity
- LOCUS (Level of Care Utilization System) for mental health needs
- K10 for psychological distress screening
These assessments evaluate substance use severity and duration, co-occurring mental health conditions, medical history and current medications, home environment stability, work and family obligations, and previous treatment experiences.
The result is a clinical recommendation based on where you actually are, not where you think you should be. If you start in PHP and make progress, you step down to IOP. If IOP is not enough structure, you step up to PHP.

How Treatment Progresses Through Levels
Effective addiction treatment is not a single event. It is a continuum. Most people move through multiple levels of care as their recovery progresses:
- Detox (if needed) for medical stabilization
- PHP for intensive daily treatment during early recovery
- IOP for continued structure with more flexibility
- Outpatient for ongoing maintenance and support
- Alumni services and community support for long-term recovery
Each step down reflects clinical progress. Your therapist at Trailhead stays with you through every level, so there are no handoffs and no repeating your history to a new provider.
Medication-assisted treatment with Vivitrol, Sublocade, or Brixadi can be integrated at any level of care for opioid or alcohol use disorders.
Frequently Asked Questions
Can I switch between PHP and IOP?
Yes. Treatment levels are adjusted based on clinical progress. If PHP is more than you need, your team steps you down to IOP. If IOP is not providing enough structure, you can step up.
Can I work while in PHP?
PHP runs 9:00 AM to 3:30 PM, five days per week. Most people in PHP are not working full-time during treatment. IOP is the better option if maintaining employment is a priority.
Does insurance cover PHP and IOP?
Most commercial insurance plans cover both PHP and IOP under the Mental Health Parity and Addiction Equity Act. Trailhead accepts Blue Cross Blue Shield, Harvard Pilgrim, Tufts, and most major plans. Call 978-915-8317 to verify your coverage.
What if I do not know which level I need?
You do not need to know before calling. The admissions team determines your level of care through a clinical assessment during the first call.
Is there a women-only option?
Trailhead offers the first women-only outpatient treatment track in New Hampshire, available within both PHP and IOP.
How quickly can I start?
Admission within 24 to 48 hours of your first call. Same-day admission may be available.
