Medicare is a type of medical health insurance designed by the U.S. government for older persons, and also people with certain disabilities and sicknesses. If someone who has Medicare needs rehab for cases of drug or alcohol abuse, their rehabilitation will be either covered in full by their Medicare insurance or to a great degree. The only real exception is, the person will have to obtain treatment from a drug rehab facility which accepts Medicare. Before the person will be allowed to commence rehab, they will also have to visit their medical doctor who must declare that rehabilitation services are medically necessary, and the physician will usually approve what sort of rehab the individual will do. Medicare Part An and Part B cover a variety of rehabilitation providers. Part A covers an inpatient stay in a Medicare accepted center when the individual has to be in a hospital for his or her problem, along with the costs that they will have to pay for personally are identical to any other stay in a hospital. Part B will partially cover outpatient rehabilitation inside a Medicare accepted center, and the individual will need to cover whatever Part B doesn't pay for with supplemental insurance coverage or they'll have to self pay.
