Medicare is a form of medical insurance developed by the government for seniors, along with those that have specific disabilities and diseases. If an individual that has Medicare needs rehabilitation for instances of substance abuse, their rehabilitation will be either covered entirely by their Medicare insurance or to a significant degree. The only real exception is, the person will have to obtain treatment from the drugs and alcohol detox facility which accepts Medicare. Before the individual will be allowed to start rehabilitation, they will also have to visit their primary care physician who must declare that rehab services are medically essential, and the doctor will generally approve what type of rehabilitation the person will do. Medicare Part An and Part B cover a variety of rehab providers. Medicare Part A pays for an inpatient stay in a Medicare accepted center when the individual needs to be hospitalized for problem, and the costs that they will have to cover personally are identical to every other hospital stay. Medicare Part B will partly cover outpatient rehabilitation within a Medicare accepted center, and the individual will have to cover whatever Medicare Part B doesn't pay for with supplement insurance coverage or they're going to have to self pay.
