Substance abuse treatment takes place in a wide variety of different treatment settings with a variety of different treatment approaches. For example, some substance abuse treatment can be done on an outpatient basis, where the person will typically participate in treatment during the day but is allowed to return home daily. Other substance abuse treatment requires the person to reside in a hospital or residential facility during the entire course of treatment, which is especially beneficial in resolving more severe cases of addiction. Inpatient and residential substance abuse treatment can be done on a short term or long term basis, depending on unique circumstances which can be different for each individual. Most substance abuse treatment will focus on getting the person physically rehabilitated, and then focus on the root psychological and emotional issues which will help them avoid relapse in the future.

Drug or alcohol rehab services which are offered on an outpatient basis are available to addicted individuals who have circumstances which prevent them from being able to participate in an inpatient rehab facility. An outpatient substance abuse rehabilitation program delivers many of the same services as an inpatient program, but allows for flexibility as opposed to an inpatient drug or alcohol rehabilitation center where the person is expected to remain at the rehabilitation center until the treatment process is complete. Outpatient drug or alcohol rehabilitation is also available for individuals who have completed residential or inpatient treatment but also need a comprehensive aftercare program which will provide additional support and treatment to help them avoid relapse.

Military health insurance normally refers to TRICARE and is a commonly recognized insurance for specific drug rehabilitation programs. A drug rehab that accepts military insurance will usually accept most other types of insurance as well. TRICARE normally covers detoxification, rehabilitation and outpatient treatment.
