Medicare is a form of health insurance developed by the federal government for older folks, as well as individuals with certain disabilities and illnesses. If a person who has Medicare needs rehabilitation for cases of substance abuse, their rehab will be either covered in full by their Medicare health insurance or to a great extent. The only catch is, the person must acquire treatment from the drug rehab facility which accepts Medicare. Before the person will be permitted to start rehab, they will also have to see their primary care physician who must declare that rehabilitation services are medically needed, and the physician will usually approve what sort of rehabilitation the individual will take part in. Medicare Part An and Part B cover a variety of rehabilitation services. Medicare Part A pays for an inpatient stay in a Medicare accepted facility if the individual must be hospitalized for their problem, as well as the costs which they willwill have to pay for personally are the same as every other hospital stay. Medicare Part B will partially cover outpatient rehabilitation inside a Medicare accepted facility, and the individual will need to cover whatever Medicare Part B doesn't pay for with supplemental insurance coverage or they're going to have to self pay.
