Medicare is a form of medical health insurance developed by the government for senior citizens, as well as those that have specific disabilities and diseases. If a person who has Medicare needs treatment for cases of drug or alcohol abuse, their rehabilitation will either be covered in full by their Medicare health insurance or to a great extent. The only real exception is, the individual will need to acquire treatment from an alcohol and drugs rehab facility which accepts Medicare. Before the person will be permitted to start rehabilitation, they will also have to visit their medical doctor who must declare that treatment services are medically needed, and the physician will usually approve what type of rehab the individual will do. Medicare Part An and Part B cover different types of rehabilitation solutions. Medicare Part A pays for an inpatient stay in a Medicare accepted center if the individual has to be in a hospital because of their problem, as well as the costs that they will have to cover personally are the same as every other hospital stay. Part B will partially cover outpatient rehabilitation in a Medicare accepted center, and the individual will have to cover whatever Medicare Part B doesn't cover with supplemental insurance coverage or they will have to self pay.
