Medicare is a type of medical health insurance created by the U.S. government for senior citizens, as well as people with certain disabilities and illnesses. When someone who has Medicare needs rehabilitation for instances of substance abuse, their rehabilitation will be either covered in full by their Medicare health insurance or to a great extent. The only exception is, the person will have to acquire treatment from a drug rehab facility which accepts Medicare. Before the person will be permitted to start rehabilitation, they may also have to visit their physician who must state that rehab services are medically necessary, and the physician will generally approve what sort of rehab the individual will take part in. Medicare Part An and Part B cover a variety of rehabilitation solutions. Medicare Part A covers an inpatient stay in a Medicare accepted facility if the individual needs to be in a hospital for his or her problem, as well as 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 in the Medicare accepted center, and the individual will have to cover whatever Medicare Part B doesn't pay for with supplemental insurance or they've got to self pay.
