Medicare is a form of health insurance designed by the U.S. government for older persons, in addition to people with specific disabilities and sicknesses. If a person that has Medicare needs rehabilitation for cases of drug or alcohol abuse, their rehab will be either covered in full by their Medicare insurance or to a significant extent. The only catch is, the person will have to receive treatment from a drug rehab facility which accepts Medicare. Before the person will be permitted to begin rehab, they will also have to see their medical doctor who must declare that rehab services are medically needed, and the doctor will typically approve which kind of treatment the person will do. Medicare Part An and Part B cover several types of rehab services. Medicare Part A pays for an inpatient stay in a Medicare accepted center if the individual has to be hospitalized for problem, and also the costs which they willwill have to cover personally are the same as every other stay in a hospital. Medicare Part B will partially cover outpatient treatment in a Medicare accepted center, and the individual will have to cover whatever Part B doesn't pay for with supplemental insurance or they'll have to self pay.
