Medicare is a kind of medical insurance designed by the federal government for older folks, and also people who have certain disabilities and sicknesses. When someone that has Medicare needs rehabilitation for cases of substance abuse, their treatment will be either covered entirely by their Medicare insurance or to a great extent. The only real exception is, the person will have to obtain treatment coming from a drug rehab facility which accepts Medicare. Before the individual will be allowed to begin treatment, they will also have to see their doctor who must declare that treatment services are medically necessary, and the physician will typically approve what type of rehab the person will do. Medicare Part An and Part B cover a variety of treatment services. Medicare Part A pays for an inpatient stay in a Medicare accepted program in the event that the individual should be in a hospital for their problem, and the costs which they willwill have to pay for personally are the same as any other stay in a hospital. Part B will partly cover outpatient rehab in a Medicare accepted program, and the individual will have to cover whatever Part B doesn't cover with supplement insurance or they will have to self pay.
