Medicare is a form of medical insurance developed by the federal government for senior citizens, in addition to people with specific disabilities and diseases. If a person who has Medicare needs treatment for instances of substance abuse, their rehabilitation will either be covered entirely by their Medicare insurance or to a significant degree. The only real exception is, the person will have to acquire treatment from your drug rehab facility which accepts Medicare. Before the individual will be allowed to begin treatment, they will also have to visit their doctor who must declare that rehab services are medically necessary, and the physician will typically approve what type of treatment the person will take part in. Medicare Part An and Part B cover different types of rehabilitation solutions. Medicare Part A pays for an inpatient stay in a Medicare accepted center when the individual should be in a hospital for problem, as well as the costs that they will have to cover personally are the same as every other hospital stay. Medicare Part B will partially cover outpatient rehab within a Medicare accepted center, and the individual will need to cover whatever Medicare Part B doesn't pay for with supplement insurance or they're going to have to self pay.
