Medicare is a sort of medical insurance designed by the U.S. government for older folks, and also individuals with certain disabilities and sicknesses. When someone who has Medicare needs rehab for cases of substance abuse, their rehab will be either covered in full by their Medicare health insurance or to a significant extent. The one exception is, the person will have to obtain treatment from the alcohol and drugs detox facility which accepts Medicare. Before the person will be allowed to begin rehabilitation, they will also have to see their primary care physician who must state that treatment services are medically necessary, and the doctor will generally approve what type of rehabilitation the person will do. Medicare Part An and Part B cover several types of treatment providers. Part A covers an inpatient stay in a Medicare accepted program when the individual needs to be in a hospital for their problem, along with the costs which they willwill have to pay for personally are the same as any other stay in a hospital. Medicare Part B will partly cover outpatient treatment in a Medicare accepted facility, and the individual will have to cover whatever Part B doesn't pay for with supplemental insurance coverage or they'll have to self pay.
