Medicare is a type of medical insurance created by the government for older folks, along with people with specific disabilities and diseases. When someone that has Medicare needs treatment for instances of substance abuse, their rehabilitation will either be covered entirely by their Medicare health insurance or to a significant extent. The only real exception is, the individual will have to obtain treatment from the drug rehab facility which accepts Medicare. Before the person will be permitted to commence rehabilitation, they may also have to visit their physician who must declare that treatment services are medically necessary, and the physician will generally approve what sort of rehabilitation the individual will do. Medicare Part An and Part B cover a variety of rehabilitation services. Medicare Part A pays for an inpatient stay in a Medicare accepted facility when the individual needs to be in a hospital because of their problem, and also the costs that they will have to cover personally are identical to any other hospital stay. Medicare Part B will partially cover outpatient rehab within a Medicare accepted center, and the individual will have to cover whatever Part B doesn't cover with supplement insurance or they'll have to self pay.
