Medicare is a type of health care insurance developed by the U.S. government for seniors, in addition to people who have certain disabilities and sicknesses. If a person that has Medicare needs rehabilitation for cases of substance abuse, their rehabilitation will be either covered completely by their Medicare health insurance or to a great degree. The only exception is, the person will have to obtain treatment coming from a drug rehab facility which accepts Medicare. Before the person will be allowed to begin rehabilitation, they will also have to see their medical doctor who must declare that rehabilitation services are medically necessary, and the physician will usually approve what type of treatment the person will do. Medicare Part An and Part B cover different types of rehabilitation providers. Medicare Part A covers an inpatient stay in a Medicare accepted program if the individual needs to be in a hospital because of their issue, along with 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 need to cover whatever Medicare Part B doesn't pay for with supplement insurance or they're going to have to self pay.
