Medicare is a form of health insurance designed by the U.S. government for seniors, and also people who have specific disabilities and illnesses. If someone who has Medicare needs rehab for cases of drug or alcohol abuse, their rehabilitation will be either covered entirely by their Medicare health insurance or to a great extent. The only exception is, the person must acquire treatment coming from a drugs and alcohol detox facility which accepts Medicare. Before the person will be allowed to start rehabilitation, they may also have to see their physician who must state that rehabilitation services are medically essential, and the doctor will generally approve what sort of treatment the person will do. Medicare Part An and Part B cover a variety of rehabilitation providers. Part A covers an inpatient stay in a Medicare accepted center if the individual must be hospitalized for their problem, and the costs which they willwill have to cover personally are the same as any other hospital stay. Part B will partially cover outpatient rehabilitation in a Medicare accepted center, and the individual will need to cover whatever Medicare Part B doesn't pay for with supplement insurance coverage or they will have to self pay.
