Medicare is a sort of medical insurance developed by the government for older folks, as well as those that have certain disabilities and diseases. When someone who has Medicare needs rehab for cases of substance abuse, their rehab will either be covered fully by their Medicare health insurance or to a significant degree. The only real exception is, the person must acquire treatment coming from a drugs and alcohol detox facility which accepts Medicare. Before the person will be allowed to start rehab, they may also have to see their primary care physician who must state that rehab services are medically necessary, and the physician will usually approve what sort of treatment the person will do. Medicare Part An and Part B cover a variety of rehab providers. Medicare Part A covers an inpatient stay in a Medicare accepted center when the individual must be hospitalized for his or her problem, as well as the costs which they willwill have to pay for personally are the same as any other hospital stay. Medicare Part B will partly cover outpatient rehab in the Medicare accepted program, and the individual will need to cover whatever Part B doesn't pay for with supplemental insurance coverage or they'll have to self pay.
