Medicare is a kind of medical insurance designed by the federal government for older persons, as well as people with specific disabilities and diseases. When someone that has Medicare needs rehabilitation for cases of drug or alcohol abuse, their treatment will either be covered entirely by their Medicare insurance or to a significant extent. The only catch is, the person must receive treatment from the drug rehab facility which accepts Medicare. Before the individual will be allowed to commence treatment, they may also have to visit their doctor who must state that rehabilitation services are medically needed, and the doctor will generally approve what sort of rehabilitation the person will do. Medicare Part An and Part B cover several types of rehabilitation services. Medicare Part A covers an inpatient stay in a Medicare accepted center if the individual must be hospitalized for his or her problem, and the costs that they will have to pay for personally are the same as any other hospital stay. Medicare Part B will partially cover outpatient treatment in a Medicare accepted center, and the individual will need to cover whatever Part B doesn't cover with supplement insurance or they've got to self pay.
