Medicare is a form of health care insurance created by the U.S. government for seniors, as well as those that have specific disabilities and illnesses. If a person who has Medicare needs treatment for cases of substance abuse, their rehabilitation will either be covered completely by their Medicare insurance or to a significant degree. The only exception is, the individual must receive treatment from a drug rehab facility which accepts Medicare. Before the individual will be permitted to begin rehab, they will also have to visit their physician who must state that treatment services are medically essential, and the physician will usually approve what sort of treatment the individual will take part in. Medicare Part An and Part B cover a variety of rehab providers. Medicare Part A covers an inpatient stay in a Medicare accepted facility in the event that the individual needs to be in a hospital because of their problem, as well as the costs that they will have to cover personally are the same as any other hospital stay. Medicare Part B will partly cover outpatient treatment inside a Medicare accepted facility, and the individual will need to cover whatever Medicare Part B doesn't cover with supplement insurance coverage or they're going to have to self pay.
