Medicare is a type of health care insurance designed by the government for senior citizens, along with individuals with certain disabilities and diseases. When someone who has Medicare needs rehabilitation for cases of substance abuse, their rehabilitation will be either covered entirely by their Medicare insurance or to a great extent. The only real catch is, the individual will have to receive treatment from the alcohol and drugs rehab facility which accepts Medicare. Before the person will be permitted to start rehabilitation, they will also have to see their primary care physician who must state that rehab services are medically essential, and the physician will generally approve what type of treatment the person will take part in. Medicare Part An and Part B cover various kinds of rehab providers. Medicare Part A pays for an inpatient stay in a Medicare accepted program when the individual has to be in a hospital because of their problem, and also the costs which they willwill have to cover personally are identical to any other hospital stay. Medicare Part B will partly cover outpatient treatment in a Medicare accepted center, and the individual will have to cover whatever Medicare Part B doesn't pay for with supplement insurance or they're going to have to self pay.
