Medicare is a sort of health insurance designed by the U.S. government for senior citizens, in addition to those that have certain disabilities and illnesses. If someone who has Medicare needs rehab for instances of substance abuse, their treatment will either be covered in full by their Medicare health insurance or to a great degree. The only exception is, the person must receive treatment from an alcohol and drugs rehab facility which accepts Medicare. Before the individual will be allowed to begin treatment, they may also have to see their physician who must state that rehabilitation services are medically necessary, and the doctor will usually approve what sort of rehabilitation the individual will do. Medicare Part An and Part B cover a variety of treatment services. Medicare Part A covers an inpatient stay in a Medicare accepted program in the event that the individual should be in a hospital for his or her issue, along with the costs which they willwill have to cover 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 need to cover whatever Part B doesn't pay for with supplemental insurance or they've got to self pay.
