Medicare is a type of medical insurance developed by the government for seniors, and also those that have certain disabilities and illnesses. If a person who has Medicare needs treatment for cases of substance abuse, their rehab will either be covered fully by their Medicare insurance or to a significant degree. The only real catch is, the individual must acquire treatment from an alcohol and drugs rehab facility which accepts Medicare. Before the person will be permitted to begin treatment, they may also have to visit their primary care physician who must declare that rehab services are medically necessary, and the physician will generally approve what type of rehabilitation the person will do. Medicare Part An and Part B cover several types of treatment services. Part A pays for an inpatient stay in a Medicare accepted facility in the event that the individual must be hospitalized because of their issue, as well as the costs which they willwill have to pay for personally are the same as every other stay in a hospital. Part B will partly cover outpatient treatment within a Medicare accepted facility, and the individual will need to cover whatever Medicare Part B doesn't cover with supplement insurance or they will have to self pay.
