- Outpatient program (OP): These are treatment programs that offer therapy, education, and social support groups. Clients can continue to work, stay at home, and tend to other responsibilities while undergoing addiction treatment.
This is the lowest level of outpatient care, generally requiring three to six hours of treatment per week.
- Intensive outpatient program (IOP): An IOP is a step up from a standard outpatient program, generally requiring a minimum of nine hours of treatment per week.
A June 2014 paper on Psychiatry Services defines IOPs as alternatives to inpatient and residential programs. They aggressively focus on preventing relapse, creating social support networks, and teaching clients to effectively deal with triggers for drug or alcohol misuse.
You can begin addiction treatment in an IOP, or you may transition to this level of care after finishing a residential program or a PHP.
- Partial hospitalization program (PHP): A PHP is a step higher than an IOP, requiring up to 30 hours of treatment per week. It is the most concentrated level of outpatient addiction treatment.
Medicare defines a partial hospitalization program as an intense program that allows clients to get treatment during the day but does not require them to live at the facility. The level of care provided in a PHP is similar to that given in an inpatient treatment program.
