Medicare is a kind of health insurance developed by the government for older folks, in addition to people who have specific disabilities and diseases. If a person who has Medicare needs rehabilitation for cases of substance abuse, their rehab will be either covered fully by their Medicare insurance or to a great extent. The only real exception is, the individual will have to obtain treatment from an alcohol and drugs detox facility which accepts Medicare. Before the individual will be allowed to begin treatment, they may also have to visit their primary care physician who must state that rehabilitation services are medically essential, and the physician will generally approve what type of rehabilitation the individual will do. Medicare Part An and Part B cover various kinds of rehab services. Part A covers an inpatient stay in a Medicare accepted center if the individual should be hospitalized because of their issue, and the costs that they will have to cover personally are identical to every other stay in a hospital. Medicare Part B will partly cover outpatient rehab inside a Medicare accepted facility, and the individual will have to cover whatever Medicare Part B doesn't cover with supplement insurance or they're going to have to self pay.
