Medicare is a type of health care insurance designed by the U.S. government for seniors, in addition to those that have specific disabilities and sicknesses. When someone who has Medicare needs treatment for instances of substance abuse, their rehabilitation will either be covered fully by their Medicare health insurance or to a significant degree. The only real exception is, the person will need to acquire treatment from the drug rehab facility which accepts Medicare. Before the individual will be allowed to start treatment, they may also have to see their primary care physician who must declare that rehab services are medically essential, and the doctor will usually approve which kind of rehabilitation the individual will take part in. Medicare Part An and Part B cover different types of rehab providers. Medicare Part A covers an inpatient stay in a Medicare accepted center when the individual has to be in a hospital for problem, and also the costs that they will have to cover personally are the same as any other hospital stay. Medicare Part B will partly cover outpatient rehab inside a Medicare accepted facility, and the individual will have to cover whatever Medicare Part B doesn't cover with supplement insurance or they've got to self pay.
