Medicare is a kind of medical health insurance created by the U.S. government for seniors, in addition to those that have specific disabilities and illnesses. When someone that has Medicare needs rehab for cases of drug or alcohol abuse, their treatment will either be covered in full by their Medicare health insurance or to a great extent. The only exception is, the individual must receive treatment from an alcohol and drugs rehab facility which accepts Medicare. Before the individual will be permitted to start treatment, they may also have to visit their physician who must state that rehab services are medically needed, and the physician will generally approve what type of treatment the person will do. Medicare Part An and Part B cover different types of rehab services. Medicare Part A covers an inpatient stay in a Medicare accepted facility in the event that the individual must be hospitalized for his or her issue, as well as the costs that they will have to pay for personally are the same as every other hospital stay. Part B will partly cover outpatient rehab inside a Medicare accepted program, and the individual will need to cover whatever Part B doesn't pay for with supplement insurance or they've got to self pay.
