Medicare is a kind of health insurance created by the federal government for older folks, and also people who have certain disabilities and diseases. When someone that has Medicare needs rehab for cases of substance abuse, their rehab will be either covered in full by their Medicare insurance or to a great extent. The only catch is, the person will have to receive 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 primary care physician who must state that rehabilitation services are medically necessary, and the physician will usually approve what sort of rehabilitation the person will do. Medicare Part An and Part B cover several types of treatment services. Medicare Part A covers an inpatient stay in a Medicare accepted center in the event that the individual should be hospitalized because of their 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 or they will have to self pay.
