Medicare is a form of medical health insurance developed by the government for senior citizens, and also those that have certain disabilities and illnesses. When someone that has Medicare needs rehab for cases of substance abuse, their treatment will either be covered entirely by their Medicare health insurance or to a great extent. The only catch 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 commence treatment, they may also have to visit their primary care physician who must state that treatment services are medically necessary, and the physician will typically approve what type of rehabilitation the person will take part in. Medicare Part An and Part B cover various kinds of rehabilitation providers. Medicare Part A pays for an inpatient stay in a Medicare accepted facility in the event that the individual has to be in a hospital because of their problem, and the costs which they willwill have to pay for personally are the same as every other stay in a hospital. Part B will partially cover outpatient rehab within a Medicare accepted program, and the individual will need to cover whatever Medicare Part B doesn't cover with supplement insurance or they will have to self pay.
