Medicare is a sort of health insurance developed by the government for seniors, as well as people who have certain disabilities and illnesses. If someone that has Medicare needs rehab for instances of substance abuse, their treatment will either be covered completely by their Medicare health insurance or to a great extent. The only real exception is, the person will need to acquire treatment from the alcohol and drugs detox facility which accepts Medicare. Before the person will be permitted to begin rehabilitation, they will also have to see their primary care physician who must state that rehabilitation services are medically necessary, and the physician will usually approve what type of rehab the individual will do. Medicare Part An and Part B cover different types of rehabilitation services. Part A covers an inpatient stay in a Medicare accepted facility if the individual has to be in a hospital for his or her problem, along with the costs which they willwill have to cover personally are identical to any other stay in a hospital. Medicare Part B will partly cover outpatient treatment in the Medicare accepted facility, and the individual will need to cover whatever Part B doesn't pay for with supplement insurance coverage or they'll have to self pay.
