Medicare is a form of medical insurance developed by the government for seniors, as well as people who have specific disabilities and illnesses. If someone that has Medicare needs rehab for instances of drug or alcohol abuse, their treatment will either be covered entirely by their Medicare insurance or to a significant degree. The only real catch is, the person will need to receive treatment from an alcohol and drugs rehab facility which accepts Medicare. Before the individual will be allowed to begin rehabilitation, they will also have to see their doctor who must state that treatment services are medically necessary, and the physician will typically approve what sort of rehabilitation the person will do. Medicare Part An and Part B cover various kinds of rehab providers. Medicare Part A pays for an inpatient stay in a Medicare accepted facility if the individual has to be in a hospital for their problem, and also the costs which they willwill have to cover personally are the same as every other hospital stay. Medicare Part B will partly cover outpatient treatment in a Medicare accepted center, and the individual will need to cover whatever Medicare Part B doesn't pay for with supplement insurance or they'll have to self pay.
