Medicare is a kind of health insurance developed by the U.S. government for senior citizens, along with people who have specific disabilities and sicknesses. When someone who has Medicare needs treatment for instances of substance abuse, their treatment will either be covered entirely by their Medicare health insurance or to a significant extent. The one exception is, the person must receive treatment from the alcohol and drugs rehab facility which accepts Medicare. Before the person will be permitted to begin rehab, they may also have to visit their physician who must state that rehabilitation services are medically needed, and the physician will usually approve what sort of rehab the individual will do. Medicare Part An and Part B cover various kinds of rehabilitation providers. Medicare Part A pays for an inpatient stay in a Medicare accepted program when the individual should be in a hospital for his or her issue, and the costs which they willwill have to cover personally are the same as every other stay in a hospital. Part B will partially cover outpatient rehab inside a Medicare accepted center, and the individual will need to cover whatever Medicare Part B doesn't cover with supplement insurance or they've got to self pay.
