Medicare is a form of medical health insurance created by the government for senior citizens, along with people with certain disabilities and diseases. When someone that has Medicare needs rehab for cases of drug or alcohol abuse, their rehab will be either covered in full by their Medicare insurance or to a great extent. The only real exception is, the person must receive treatment from an alcohol and drugs detox facility which accepts Medicare. Before the individual will be permitted to begin rehab, they may also have to visit their doctor who must declare that rehabilitation services are medically necessary, and the physician will usually approve what sort of rehabilitation the individual will do. Medicare Part An and Part B cover several types of rehab services. Part A pays for an inpatient stay in a Medicare accepted center when the individual should be in a hospital because of their issue, and the costs which they willwill have to cover personally are the same as every other hospital stay. Part B will partly cover outpatient rehab within a Medicare accepted program, and the individual will need to cover whatever Medicare Part B doesn't pay for with supplement insurance or they're going to have to self pay.
