Medicare is a kind of medical health insurance developed by the U.S. government for seniors, in addition to individuals with specific disabilities and diseases. If a person that has Medicare needs rehabilitation for cases of substance abuse, their rehabilitation will either be covered in full by their Medicare insurance or to a great extent. The only real exception is, the person will need to obtain treatment from an alcohol and drugs rehab facility which accepts Medicare. Before the person will be allowed to begin treatment, they will also have to see their medical doctor who must declare that treatment services are medically necessary, and the physician will usually approve what type of rehabilitation the individual will take part in. Medicare Part An and Part B cover different types of rehab services. Medicare Part A covers an inpatient stay in a Medicare accepted center in the event that the individual needs to be hospitalized because of their problem, as well as the costs which they willwill have to cover personally are identical to every other hospital stay. Medicare Part B will partly cover outpatient rehabilitation within a Medicare accepted facility, and the individual will need to cover whatever Part B doesn't pay for with supplement insurance or they will have to self pay.
