Medicare is a form of medical health insurance designed by the federal government for older folks, as well as people who have certain disabilities and illnesses. If an individual that has Medicare needs rehab for instances of substance abuse, their rehabilitation will either be covered fully by their Medicare health insurance or to a significant degree. The only real catch is, the individual must receive treatment from your drug rehab facility which accepts Medicare. Before the individual will be permitted to begin rehabilitation, they will also have to visit their doctor who must state that treatment services are medically essential, and the doctor will typically approve what type of rehabilitation the person will do. Medicare Part An and Part B cover a variety of treatment services. Part A covers an inpatient stay in a Medicare accepted facility if the individual has to be hospitalized for his or her problem, as well as the costs which they willwill have to pay for personally are identical to every other stay in a hospital. Medicare Part B will partially cover outpatient rehab inside a Medicare accepted program, and the individual will have to cover whatever Part B doesn't cover with supplemental insurance or they'll have to self pay.
