Partial Hospitalization, also known as "PHP" or Day Treatment, is a form of treatment program which works to treat substance abuse issues and mental health issues which may be co-occurring. In a PHP program, the individual in treatment takes part in various treatment activities and techniques during the day and then returns home in the evening. This takes place anywhere from five to seven days a week, depending on the severity of the problem. Partial Hospitalization can be helpful for addicted persons who may not be able to afford long-term inpatient care, or who are unable to be away from their families for prolonged periods of time. While in Day Treatment, individuals take part in typical counseling and therapy for addiction issues while also addressing mental health issues which could prevent them from making progress and obtaining gains throughout the treatment process.

Persons with co-occurring mental and substance abuse disorders must address both issues in order to become fully rehabilitated. Some individuals take drugs to alleviate symptoms of mental health problems, and some people take drugs which then, in turn, causes symptoms which mimic mental health problems, such as anxiety and depression. Addiction rehabilitation professionals know how to differentiate between the two, and can work with clients to properly treat real mental health conditions in tandem with any other substance abuse treatment that is done with the person. This has proven to be effective in keeping individuals with mental health issues off of drugs and alcohol and mentally stable and productive.

Medicaid is a type of health insurance which is offered to individuals in certain low-income tax brackets. Eligibility for Medicaid is dependent on income and other factors such as whether or not the individual has dependents and if they receive any other financial assistance. Medicaid may possibly even cover the costs associated with drug treatment, and there are many drug treatment programs throughout the country which are covered through Medicaid. Most drug rehab programs which are covered through Medicaid may only provide a limited treatment curriculum and may only supply such treatment on a short term basis, usually 30 days or less. Individuals who have Medicaid should look for which programs cover the greatest amount of treatment for the most amount of time to reap the full benefits of a Medicaid rehab program.
