Medicare is a kind of medical health insurance designed by the U.S. government for seniors, along with people with specific disabilities and sicknesses. If a person who has Medicare needs rehab for cases of substance abuse, their treatment will be either covered entirely by their Medicare insurance or to a significant extent. The only catch is, the individual will need to receive treatment from the drugs and alcohol detox facility which accepts Medicare. Before the person will be permitted to begin treatment, they may also have to see their medical doctor who must declare that rehab services are medically necessary, and the doctor will generally approve what sort of treatment the person will do. Medicare Part An and Part B cover various kinds of rehabilitation services. Medicare Part A pays for an inpatient stay in a Medicare accepted facility when the individual must be in a hospital for his or her problem, as well as the costs which they willwill have to pay for personally are the same as every other hospital stay. Medicare Part B will partially cover outpatient treatment inside a Medicare accepted center, and the individual will have to cover whatever Part B doesn't pay for with supplemental insurance or they will have to self pay.
