Medicare accepted alcohol and drug rehab facilities accept this form of medical insurance that is provided solely to older Americans as well as people with certain disabilities and chronic illnesses. There are a few different kinds of Medicare, and the type of treatment that is covered in a Medicare accepted alcohol and drug rehab program is dependent upon which type of Medicare someone is covered under. For example, Medicare Part A covers inpatient drug rehab facilities in the event the rehab client needs hospitalization to deal with their drug abuse problem. Individuals covered by Medicare Part A will need to cover the normal cost they would be asked to pay for every other hospital stay. Medicare Part B will partially cover outpatient treatment inside a Medicare accepted program, and whatever Medicare Part B doesn't cover the person will need to pay for themselves or through some other type of supplemental insurance coverage. People who need rehab for substance abuse can't use their Medicare health coverage at just any center, and they will need to locate a Medicare accepted program unless they want to self-pay for their rehab. Medicare can provide a directory of Medicare accepted treatment providers to make the job of finding a Medicare accepted facility somewhat easier.
