Medicare is a form of health care insurance created by the U.S. government for older folks, as well as people with specific disabilities and diseases. If an individual who has Medicare needs rehabilitation for cases of drug or alcohol abuse, their rehab will be either covered fully by their Medicare health insurance or to a significant extent. The only real exception is, the person must acquire treatment from a drug rehab facility which accepts Medicare. Before the person will be allowed to commence rehabilitation, they may also have to see their medical doctor who must state that rehab services are medically necessary, and the doctor will typically approve which kind of treatment the person will take part in. Medicare Part An and Part B cover various kinds of rehabilitation providers. Medicare Part A covers an inpatient stay in a Medicare accepted facility if the individual should be in a hospital because of their problem, and also the costs that they will have to pay for personally are identical to any other hospital stay. Medicare Part B will partly cover outpatient treatment within a Medicare accepted facility, and the individual will have to cover whatever Medicare Part B doesn't cover with supplement insurance coverage or they will have to self pay.
