Medicare is a kind of medical insurance developed by the government for senior citizens, as well as people who have certain disabilities and diseases. If a person who has Medicare needs rehab for instances of drug or alcohol abuse, their rehab will be either covered completely by their Medicare insurance or to a great extent. The only real exception is, the person will need to receive treatment from an alcohol and drugs rehab facility which accepts Medicare. Before the person will be allowed to start rehabilitation, they can also get to see their primary care physician who must declare that rehab services are medically necessary, and the doctor will usually approve what sort of rehab the individual will do. Medicare Part An and Part B cover a variety of rehab solutions. Part A pays for an inpatient stay in a Medicare accepted program when the individual needs to be hospitalized for his or her problem, along with the costs which they willwill have to cover personally are the same as every other hospital stay. Part B will partially cover outpatient rehabilitation inside a Medicare accepted program, and the individual will need to cover whatever Medicare Part B doesn't cover with supplement insurance coverage or they will have to self pay.
