Dealing with drug and alcohol addiction isn’t easy, both for the person who uses substances as well as those who know and love them. Different levels of outpatient care, including one known as a partial hospitalization program (PHP), have helped many people begin their recovery from substance use disorder (SUD).1 PHPs are a step on the path to recovery, which can include a continuum of different levels of care options, depending on an individual’s treatment needs.2
Finding the right PHP addiction treatment can help individuals find peace of mind and support their recovery efforts. This article will help you understand what PHPs are, what to expect in a PHP, and what happens after someone completes PHP treatment. It will also provide an overview on insurance coverage for PHP rehab and discuss how you can find PHP treatment near you.
A partial hospitalization program is the most intensive level of outpatient treatment. PHP provides rehab services to people who require a highly supportive level of care.1,2 When appropriate, it can serve as an alternative to inpatient and residential treatment in that it provides access to a similar range of relatively intensive recovery services but allows those who need daily monitoring and management to return to their home or other sober living environment outside of treatment hours.1,2
People who may be good candidates for a PHP include those who have significant medical or co-occurring mental health conditions like bipolar disorder or depression, but have relatively stable home environments, reliable transportation, and a sufficient level of social support.1,2
Alternately referred to as day treatment programs or high-intensity outpatient programs (HIOP), partial hospitalization programs represent the most intensive level of outpatient treatment—falling between inpatient care and traditional outpatient treatment in terms of treatment intensity according to the American Society of Addiction Medicine (ASAM).2 The full ASAM continuum of care includes:2
People have different needs, and these needs can change as an individual progresses in their recovery, which means that people can transition between different levels of care.3 PHPs can serve as a starting point in addiction treatment or a continuation of care.2 For example, a PHP rehab for drug or alcohol addiction can be used as a step-down form of care following inpatient or residential treatment, a step-up from an IOP or other less intensive form of outpatient care, or as the entry point to treatment for some individuals.2,4
The most appropriate level of care can be best determined with the help of a doctor or addiction specialist. Ideally, before starting treatment, patients will undergo a comprehensive evaluation to help determine the severity of their SUD, any other mental or medical diagnoses that require treatment attention, as well as other recovery needs to help formulate an individualized treatment plan and the most suitable level of care.1,2 A person’s specific treatment plan can vary depending on the substance they use, their unique needs, and the facility that they attend.3
According to the Substance Abuse and Mental Health Services Administration (SAMHSA), treatment outcomes in intensive outpatient programs, which include PHPs, are comparable to inpatient treatment but at nearly half the cost.4 However, it’s important to note that not all treatment centers offer PHPs.
If you’re considering a partial hospitalization program, you might be wondering what happens in PHP rehab.
When appropriate, a person may begin their treatment program with medically supervised detox on an outpatient basis, to help them safely and comfortably manage their withdrawal symptoms at the start of recovery.1 Detox can take place in a separate detox program or in the PHP itself, although PHPs that offer detox services generally treat people with mild-to-moderate withdrawal symptoms and will refer someone who requires a higher level of care to the appropriate detox setting.1,5
The individual can then expect to receive a variety of services and participate in different interventions and therapies during their PHP program. This can include:
In general, people attend a PHP most days of the week for 4 to 8 hours per day, and can then leave the program and return home.1 This differs from other levels of care, including more traditional outpatient appointments, which may only require attending treatment 1 to 3 times per week in the evenings or weekends, or residential treatment, where a person lives onsite at a rehab for the duration of treatment.7 As with other forms of treatment, the exact duration of a PHP can vary depending on a person’s needs but may last 3 or more months.1
Recovery is a lifelong process, which is why it’s important to have an aftercare plan in place following treatment at a PHP rehab for drugs or alcohol.1Aftercare, also known as continuing care, helps to provide continued recovery support after an initial period of more structured treatment has ended.3 Following PHP treatment and depending on their needs, people may participate in different types of aftercare, such as:
Health insurance may cover at least part of the cost of a partial hospitalization program.10 Every insurance plan is different, but health insurance providers are required to offer some level of coverage for addiction treatment since it is considered an essential health benefit under the Affordable Care Act.10 Insurance companies also generally have to cover mental health and substance abuse treatment in a way that is similar to their coverage of medical and surgical care.10
Seeking addiction treatment is an important step in regaining control of your life. No matter how things might seem right now, there’s always hope. Prompt and appropriate treatment can help people safely stop using drugs to lead healthier lives with their families, at work, and within their communities.3
