Medicare is a type of health care insurance developed by the government for older persons, in addition to individuals with specific disabilities and diseases. If an individual who has Medicare needs treatment for cases of drug or alcohol abuse, their rehabilitation will be either covered completely by their Medicare health insurance or to a great extent. The only real exception is, the individual will need to receive treatment from the drug rehab facility which accepts Medicare. Before the person will be permitted to commence rehabilitation, they will also have to visit their doctor who must declare that treatment services are medically essential, and the doctor will usually approve what sort of treatment the person will do. Medicare Part An and Part B cover various kinds of rehab providers. Medicare Part A covers an inpatient stay in a Medicare accepted center if the individual has to be hospitalized for his or her problem, and also the costs which they willwill have to pay for personally are the same as any other stay in a hospital. Part B will partially cover outpatient treatment within a Medicare accepted program, and the individual will have to cover whatever Part B doesn't pay for with supplement insurance coverage or they will have to self pay.
