Medicare is a kind of medical health insurance created by the U.S. government for older persons, and also people who have certain disabilities and illnesses. If someone who has Medicare needs rehabilitation for cases of drug or alcohol abuse, their rehab will either be covered fully by their Medicare insurance or to a great extent. The only real catch is, the person will have to receive treatment from your drug rehab facility which accepts Medicare. Before the individual will be permitted to start rehabilitation, they will also have to see their doctor who must state that rehab services are medically necessary, and the physician will usually approve what sort of treatment the person will do. Medicare Part An and Part B cover a variety of rehab providers. Part A pays for an inpatient stay in a Medicare accepted center when the individual should be in a hospital for their problem, along with the costs which they willwill have to pay for personally are identical to every other hospital stay. Medicare Part B will partially cover outpatient rehab inside a Medicare accepted program, and the individual will need to cover whatever Medicare Part B doesn't cover with supplement insurance or they'll have to self pay.
