Medicare is a type of medical insurance designed by the U.S. government for senior citizens, as well as people who have specific disabilities and sicknesses. If an individual that has Medicare needs treatment for cases of substance abuse, their treatment will be either covered in full by their Medicare health insurance or to a great extent. The one exception is, the person will have to obtain treatment coming from a drug rehab facility which accepts Medicare. Before the individual will be allowed to start treatment, they will also have to see their primary care physician who must declare that rehabilitation services are medically necessary, and the physician will usually approve what type of rehab the person will do. Medicare Part An and Part B cover various kinds of rehabilitation services. Medicare Part A covers an inpatient stay in a Medicare accepted center when the individual should be in a hospital for his or her issue, as well as the costs which they willwill have to pay for personally are identical to any other hospital stay. Medicare Part B will partially cover outpatient rehab inside a Medicare accepted program, and the individual will need to cover whatever Medicare Part B doesn't pay for with supplement insurance or they will have to self pay.
