What Types of Rehab Treatment Does Medicare Cover?

With most Medicaid plans covering at least some of the costs of rehab treatment for alcohol addiction or drug addiction, the types of treatment can vary in intensity and frequency. Types of treatment may include:4,5

  • Detox services: In some cases, you may need assistance when detoxing from drugs and alcohol, which can potentially be uncomfortable, painful, or even life threatening. Medical detox helps you safely withdrawal from drugs and alcohol, as you’ll receive around-the-clock medical supervision. You might also be given medications to help minimize withdrawal symptoms.
  • Inpatient or residential care: Inpatient/residential live-in treatment centers provide drug and alcohol rehab while you live onsite at the facility. Most inpatient programs last anywhere from 15–90 days, depending on the program you’re in and your individual needs.
  • Partial hospitalization (PHP): Partial hospitalization programs give you the opportunity to live at home while attending treatment during the day.
  • Intensive outpatient program (IOP): Intensive outpatient programs involve attending treatment programs a few evenings a week. In an intensive outpatient program, you can live at home and even go to work during the day.
  • Outpatient treatment: Individuals who have completed inpatient treatment often attend outpatient treatment for ongoing support on their journey to sobriety. You live at home and spend 10–12 hours a week at the treatment facility for therapy and support.

When you decide to get treatment for a drug or alcohol addiction, you will need to decide what type of treatment is best for you.
