Medicare is a kind of health insurance developed by the U.S. government for older folks, as well as people who have certain disabilities and illnesses. When someone that has Medicare needs treatment for cases of substance abuse, their rehab will be either covered fully by their Medicare insurance or to a significant extent. The only catch is, the person must receive treatment from an alcohol and drugs rehab facility which accepts Medicare. Before the individual will be allowed to begin rehab, they may also have to see their primary care physician who must declare that rehab services are medically essential, and the doctor will usually approve what sort of rehabilitation the person will do. Medicare Part An and Part B cover several types of treatment providers. Medicare Part A covers an inpatient stay in a Medicare accepted facility in the event that the individual has to be hospitalized for his or her problem, and also the costs which they willwill have to pay for personally are the same as any other hospital stay. Medicare Part B will partially cover outpatient treatment inside a Medicare accepted facility, and the individual will have to cover whatever Part B doesn't pay for with supplement insurance or they'll have to self pay.
