Medicare is a kind of health care insurance developed by the government for older persons, as well as people who have certain disabilities and illnesses. If someone that has Medicare needs rehabilitation for cases of substance abuse, their rehab will either be covered in full by their Medicare insurance or to a significant degree. The only real exception is, the individual must acquire treatment from a drug rehab facility which accepts Medicare. Before the person will be allowed to begin treatment, they will also have to see their doctor who must state that rehabilitation services are medically needed, and the physician will usually approve what sort of treatment the individual will do. Medicare Part An and Part B cover various kinds of treatment services. Medicare Part A pays for an inpatient stay in a Medicare accepted facility when the individual should be hospitalized because of their problem, along with the costs that they will have to pay for personally are the same as any other hospital stay. Part B will partially cover outpatient rehabilitation within a Medicare accepted facility, and the individual will need to cover whatever Part B doesn't pay for with supplemental insurance coverage or they will have to self pay.
