Medicare is a kind of health care insurance designed by the U.S. government for seniors, and also people with certain disabilities and sicknesses. If an individual who has Medicare needs treatment for instances of substance abuse, their treatment will either be covered completely by their Medicare health insurance or to a significant degree. The only exception is, the individual will need to receive treatment from an alcohol and drugs rehab facility which accepts Medicare. Before the person will be allowed to start rehab, they can also get to see their doctor who must state that rehab services are medically needed, and the doctor will usually approve which kind of rehab the individual will do. Medicare Part An and Part B cover various kinds of treatment services. Medicare Part A pays for an inpatient stay in a Medicare accepted program when the individual must be in a hospital because of their problem, and the costs which they willwill have to pay for personally are the same as any other stay in a hospital. Medicare Part B will partly cover outpatient treatment in a Medicare accepted program, and the individual will have to cover whatever Medicare Part B doesn't cover with supplement insurance coverage or they will have to self pay.
