Medicare is a sort of medical health insurance designed by the U.S. government for senior citizens, along with people with certain disabilities and sicknesses. If an individual who has Medicare needs rehab for instances of substance abuse, their rehab will either be covered entirely by their Medicare insurance or to a significant extent. The only catch is, the person will need to acquire treatment from your alcohol and drugs detox facility which accepts Medicare. Before the individual will be allowed to start rehabilitation, they may also have to visit their primary care physician who must state that rehab services are medically necessary, and the physician will usually approve what type of rehab the individual will do. Medicare Part An and Part B cover several types of treatment providers. Part A pays for an inpatient stay in a Medicare accepted center if the individual must be hospitalized for his or her issue, along with the costs that they will have to cover personally are the same as every other stay in a hospital. Part B will partly cover outpatient rehab within a Medicare accepted center, and the individual will have to cover whatever Part B doesn't pay for with supplemental insurance coverage or they're going to have to self pay.
