Medicare is a kind of health insurance developed by the U.S. government for senior citizens, as well as people who have certain disabilities and diseases. If someone that has Medicare needs rehabilitation for cases of drug or alcohol abuse, their rehabilitation will either be covered fully by their Medicare insurance or to a great degree. The only catch is, the person must receive treatment from a drug rehab facility which accepts Medicare. Before the person will be allowed to start treatment, they will also have to see their physician who must state that rehab services are medically needed, and the doctor will generally approve what type of rehab the person will do. Medicare Part An and Part B cover a variety of treatment services. Medicare Part A pays for an inpatient stay in a Medicare accepted center if the individual should be hospitalized for problem, as well as the costs which they willwill have to cover personally are identical to every other hospital stay. Medicare Part B will partly cover outpatient rehab inside a Medicare accepted center, and the individual will have to cover whatever Part B doesn't pay for with supplemental insurance coverage or they'll have to self pay.
