Medicare is a sort of medical insurance developed by the U.S. government for older folks, in addition to those that have specific disabilities and diseases. If someone that has Medicare needs rehab for cases of substance abuse, their treatment will either be covered fully by their Medicare insurance or to a significant degree. The only exception is, the individual will have to acquire treatment from your drug rehab facility which accepts Medicare. Before the individual will be permitted to start rehabilitation, they may also have to see their doctor who must declare that rehab services are medically necessary, and the physician will generally approve what type of rehabilitation the person will do. Medicare Part An and Part B cover different types of rehab providers. Part A pays for an inpatient stay in a Medicare accepted program when the individual has to be hospitalized for his or her problem, and the costs that they will have to cover personally are the same as every other hospital stay. Part B will partially cover outpatient rehab within a Medicare accepted center, and the individual will have to cover whatever Medicare Part B doesn't pay for with supplemental insurance coverage or they've got to self pay.
