Medicare is a sort of health care insurance created by the U.S. government for seniors, in addition to people who have specific disabilities and diseases. When someone who has Medicare needs rehabilitation for instances of substance abuse, their rehab will either be covered entirely by their Medicare insurance or to a great extent. The only exception is, the person will need to acquire treatment from the alcohol and drugs detox facility which accepts Medicare. Before the person will be allowed to begin treatment, they may also have to see their physician who must state that rehabilitation services are medically necessary, and the physician will typically approve what type of rehab the person will take part in. Medicare Part An and Part B cover different types of rehab providers. Medicare Part A pays for an inpatient stay in a Medicare accepted facility when the individual should be in a hospital for their issue, as well as the costs that they will have to cover personally are identical to any other stay in a hospital. Medicare Part B will partly cover outpatient rehab 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.
