Medicare is a form of medical health insurance developed by the government for seniors, as well as individuals with specific disabilities and diseases. When someone who has Medicare needs treatment for instances of substance abuse, their rehabilitation will either be covered in full by their Medicare health insurance or to a great extent. The only real catch is, the individual must acquire treatment from your drug rehab facility which accepts Medicare. Before the person will be allowed to commence treatment, they will also have to visit their primary care physician who must state that treatment services are medically needed, and the doctor will usually approve what type of treatment the person will take part in. Medicare Part An and Part B cover different types of treatment services. Part A covers an inpatient stay in a Medicare accepted center in the event that the individual must be in a hospital for their problem, and the costs which they willwill have to pay for personally are the same as every other stay in a hospital. Medicare Part B will partially cover outpatient treatment in a Medicare accepted center, and the individual will have to cover whatever Medicare Part B doesn't cover with supplement insurance coverage or they will have to self pay.
