Medicare is a form of health insurance created by the U.S. government for older persons, in addition to people who have specific disabilities and illnesses. If someone that has Medicare needs rehab for cases of substance abuse, their treatment will either be covered entirely by their Medicare health insurance or to a great extent. The only real exception is, the individual must obtain treatment coming from an alcohol and drugs rehab facility which accepts Medicare. Before the individual will be permitted to start rehabilitation, they will also have to visit their primary care physician who must declare that rehab services are medically essential, and the physician will typically approve what type of rehabilitation the individual will do. Medicare Part An and Part B cover various kinds of rehabilitation providers. Part A covers an inpatient stay in a Medicare accepted facility in the event that the individual needs to be in a hospital for his or her issue, as well as the costs which they willwill have to cover personally are the same as every other stay in a hospital. Part B will partially cover outpatient rehabilitation within a Medicare accepted program, and the individual will have to cover whatever Part B doesn't cover with supplemental insurance coverage or they'll have to self pay.
