Medicare is a type of health care insurance developed by the federal government for seniors, and also people with certain disabilities and sicknesses. If a person who has Medicare needs treatment for instances of substance abuse, their rehab will either be covered entirely by their Medicare insurance or to a great extent. The only real exception is, the individual will have to acquire treatment from your drug rehab facility which accepts Medicare. Before the person will be allowed to begin rehabilitation, they will also have to see their primary care physician who must state that treatment 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 several types of rehabilitation services. Medicare Part A pays for an inpatient stay in a Medicare accepted facility in the event that the individual should be in a hospital for his or her problem, along with the costs which they willwill have to pay for personally are identical to any other hospital stay. Medicare Part B will partly cover outpatient treatment inside a Medicare accepted program, and the individual will need to cover whatever Part B doesn't pay for with supplement insurance coverage or they're going to have to self pay.
