If you’re looking for addiction treatment in Massachusetts, you may notice something odd: programs that offer the same care as a PHP or IOP are listed under different names. It’s not a mistake; it’s a legal distinction unique to this state.
In MA, providers use terms like Day Treatment because the state has specific rules about how clinical models must be named and licensed. These rules help keep things safe, consistent, and transparent.
This blog will walk you through what PHP and IOP usually mean, how Massachusetts defines them, and what to look for when choosing the right level for you or your loved one.
What Are PHP and IOP?
Across the United States, mental health and substance use rehab centers often use the terms “Partial Hospitalization Program” (PHP) and “Intensive Outpatient Program” (IOP) to describe levels of care.
These labels help describe how much monitoring someone receives in a given week, but they’re not always legal terms for billing or licensing. In Massachusetts, for example, options that offer PHP or IOP-level services are licensed instead as Day Treatment under the state’s official categories.
Think of it like a care ladder:
Inpatient → PHP → IOP → Outpatient
Each step down reflects a lower intensity of clinical support and a higher level of personal independence. Understanding where a program fits on this scale can help you compare your options, especially when the naming varies by state.
Partial Hospitalization Program (PHP)
A PHP program provides a high level of oversight without staying overnight. It’s often used after detox or residential services. Most PHP mental health or substance use treatment includes:
- 5 to 6 hours of structured therapy per day
- Sessions 5 days per week
- Group, individual, and family therapy
- Psychiatric care and medication management
PHP is ideal after inpatient treatment or for people who need full-day guidance to manage symptoms.
Intensive Outpatient Program (IOP)
An IOP program offers flexibility with fewer hours than PHP. It’s a good option for people stepping down from higher levels or those who don’t need full-day support. Typical features:
- 3 to 4 hours of therapy per day
- Sessions 3 to 5 days per week
- Group, individual therapy, and psychiatric check-ins
- Dual diagnosis services
An IOP mental health or addiction track still features clinical help and structure, but the schedule is easier to balance with daily life.
How Massachusetts Labels These Programs
Here’s where it gets specific. MA does not use the terms “PHP” or “IOP” in official licenses.
Instead, under 105 CMR 164 (the state regulation governing substance use treatment licensing), facilities must register under these categories:
- Day Treatment (DT)
- Extended Day Treatment (EDT)
These align with what some insurers call PHP and IOP in terms of format and intensity. In other words, they meet the same clinical needs. The difference lies in the legal terminology used by the state.
Day Treatment
Day Treatment is the Massachusetts-approved label for treatment tracks that offer:
- 3 to 4 hours of structured clinical supervision per day
- Group therapy, individual therapy, and psychiatric services
- Dual diagnosis support for mental health and substance use
This mirrors the clinical criteria of an IOP used by insurance providers, but follows the naming rules under 105 CMR 164.
Extended Day Treatment
Extended Day Treatment provides more intensive recovery services and includes:
- 5 to 6 hours of care per day
- Trauma-informed, experiential, and wellness-focused options
- Full clinical oversight and dual diagnosis therapy
- A full-day schedule for those needing more monitoring
This mirrors the national standards for a PHP, but MA requires facilities to use the EDT label.
Why “PHP” and “IOP” Aren’t Used in Massachusetts
Every addiction treatment center in this state must follow specific licensing rules. The Massachusetts Department of Public Health (DPH) and Bureau of Substance Addiction Services (BSAS) oversee these rules. They regulate what programs can be called under 105 CMR 164.
The approved categories are:
- Day Treatment (DT)
- Extended Day Treatment (EDT)
- Structured Outpatient Addiction Program (SOAP)
- Outpatient (OP)
Terms like PHP and IOP are not on the approved list. That means even if a program is clinically comparable to those treatment levels, it cannot legally use those labels for marketing, documentation, or billing purposes. And this isn’t just a technicality either; the state enforces these naming rules as part of a standardized licensing system that all providers must follow.
Licensing matters because it ensures safety, consistency, and transparency. It also protects your rights as a client and supports valid insurance claims. Using unlicensed terms like “PHP” or “IOP” can lead to insurance denials or delayed reimbursements if the program isn’t aligned with official definitions.
Day Treatment vs. Extended Day Treatment: What’s the Difference?
While these two names sound similar, they reflect both clinical and licensing differences in MA. Here’s a side-by-side comparison to help you understand the two options:
| Feature | Day Treatment | Extended Day Treatment |
|---|---|---|
| Hours per Day | 3–4 | 5–6 |
| Days per Week | 3–5 | 5 |
| Includes Psychiatric Offerings | Yes | Yes |
| Group and Individual Therapy | Yes | Yes |
| Experiential Therapies | Sometimes | Often |
| Educational Support (Youth) | No | Yes (in youth programs) |
| Dual Diagnosis Services | Often | Always |
| Matches National | IOP | PHP |
How to Tell If a Program Offers PHP or IOP-Level Care
Since outpatient rehab programs may not use these national terms, here’s how to evaluate whether a service meets your needs. Ask these questions when comparing your options:
- How many hours of clinical oversight do I receive each week?
- Are therapy sessions individual, group-based, or both?
- Will I have access to psychiatric care and medication management?
- Are staff licensed and credentialed?
- Do they offer trauma-informed or dual diagnosis therapies?
- How is the family involved in the process?
Remember: The label matters less than the services provided.
What to Look for in a Licensed Massachusetts Program
Not all rehabs meet the same standards. Look for signs that a program is properly certified and aligns with your needs.
A high-quality licensed facility in Massachusetts will include:
- Active licensure through DPH/BSAS
- Staff with relevant credentials and clinical experience
- Help for co-occurring mental health and substance use disorders
- Family therapy and aftercare/discharge planning
- Clear policies and safety protocols
These features ensure you receive evidence-based care in a setting that meets state standards. They also protect your rights and support insurance claims.
Getting the Right Care, No Matter What It’s Called
We know the language around addiction treatment can be confusing. In Massachusetts, “PHP” and “IOP” may not appear on a provider’s website, but the oversight you need is still available under other names. It’s the structure, quality, and support behind the service that count.
At New Growth Recovery, we offer both Day Treatment and Extended Day Treatment. These programs deliver the same level of care you’d expect from IOP or PHP, tailored to your needs and licensed by the state.
