Medicare is a sort of medical health insurance developed by the government for older persons, as well as those that have specific disabilities and illnesses. If an individual that has Medicare needs rehabilitation for instances of substance abuse, their rehab will be either covered entirely by their Medicare insurance or to a great extent. The only catch is, the person will have to acquire treatment from a drugs and alcohol detox facility which accepts Medicare. Before the individual will be allowed to begin rehabilitation, they may also have to see their primary care physician who must state that treatment services are medically essential, and the physician 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 facility when the individual needs to be hospitalized for their problem, and the costs that they will have to pay for personally are the same as any other hospital stay. Medicare Part B will partly cover outpatient treatment inside a Medicare accepted center, and the individual will have to cover whatever Part B doesn't pay for with supplement insurance coverage or they'll have to self pay.
