Medicare is a sort of health insurance designed by the government for older persons, in addition to people who have certain disabilities and sicknesses. When someone who has Medicare needs rehabilitation for instances of substance abuse, their treatment will be either covered entirely by their Medicare insurance or to a significant degree. The one catch is, the individual must acquire treatment from the alcohol and drugs rehab facility which accepts Medicare. Before the person will be allowed to start rehab, they may also have to visit their primary care physician who must declare that rehab services are medically necessary, and the doctor will usually approve what type of treatment the individual will take part in. Medicare Part An and Part B cover different types of rehabilitation services. Part A covers an inpatient stay in a Medicare accepted program when the individual must be in a hospital for their problem, as well as the costs that they will have to cover personally are identical to every other stay in a hospital. Part B will partially cover outpatient rehabilitation within a Medicare accepted center, and the individual will need to cover whatever Medicare Part B doesn't cover with supplemental insurance coverage or they're going to have to self pay.
