Medicare is a kind of health care insurance designed by the federal government for senior citizens, along with individuals with certain disabilities and diseases. If an individual that has Medicare needs rehabilitation for cases of substance abuse, their rehab will either be covered in full by their Medicare health insurance or to a significant extent. The only exception is, the individual will have to acquire treatment from the drugs and alcohol detox facility which accepts Medicare. Before the person will be allowed to start rehab, they may also have to visit their primary care physician who must declare that rehab services are medically necessary, and the physician will typically approve which kind of rehab the individual will do. Medicare Part An and Part B cover various kinds of rehabilitation services. Medicare Part A pays for an inpatient stay in a Medicare accepted center in the event that the individual needs to be in a hospital for his or her issue, as well as the costs that they will have to pay for personally are the same as every other hospital stay. Part B will partly cover outpatient rehab within a Medicare accepted program, and the individual will need to cover whatever Medicare Part B doesn't cover with supplemental insurance coverage or they're going to have to self pay.
