Medicare is a kind of medical insurance designed by the government for seniors, in addition to people who have specific disabilities and sicknesses. If a person who has Medicare needs treatment for cases of substance abuse, their treatment will either be covered in full by their Medicare health insurance or to a great extent. The only real exception is, the individual will have to receive treatment coming from a drug rehab facility which accepts Medicare. Before the individual will be permitted to start treatment, they may 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 rehabilitation the person will do. Medicare Part An and Part B cover different types of rehab services. Medicare Part A pays for an inpatient stay in a Medicare accepted center if the individual has to be hospitalized for his or her problem, and also the costs which they willwill have to cover personally are the same as any other hospital stay. Part B will partially cover outpatient rehab inside a Medicare accepted program, and the individual will need to cover whatever Medicare Part B doesn't cover with supplement insurance coverage or they've got to self pay.
