Medicare is a form of health insurance created by the U.S. government for older folks, in addition to individuals with certain disabilities and sicknesses. If an individual who has Medicare needs rehabilitation for cases of substance abuse, their rehabilitation will be either covered fully by their Medicare health insurance or to a great extent. The only real exception is, the person will have to obtain treatment from the alcohol and drugs rehab facility which accepts Medicare. Before the person will be allowed to start rehabilitation, they may also have to see their physician who must declare that rehabilitation services are medically necessary, and the physician will generally approve which kind of treatment the individual will do. Medicare Part An and Part B cover a variety of treatment solutions. Medicare Part A covers an inpatient stay in a Medicare accepted program if the individual must be hospitalized because of their problem, and the costs which they willwill have to cover personally are the same as every other stay in a hospital. Medicare Part B will partially cover outpatient treatment inside a Medicare accepted facility, and the individual will have to cover whatever Part B doesn't cover with supplement insurance or they will have to self pay.
