Medicare is a type of medical health insurance designed by the U.S. government for seniors, as well as people with certain disabilities and illnesses. If someone who has Medicare needs rehab for cases of drug or alcohol abuse, their treatment will either be covered entirely by their Medicare insurance or to a great extent. The only catch is, the person will need to acquire treatment from a drug rehab facility which accepts Medicare. Before the individual will be permitted to begin rehabilitation, they may also have to visit their physician who must declare that rehab services are medically necessary, and the doctor will usually approve which kind of rehab the person will take part in. Medicare Part An and Part B cover a variety of treatment services. Medicare Part A covers an inpatient stay in a Medicare accepted facility when the individual has to be in a hospital for issue, and also the costs which they willwill have to pay for 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're going to have to self pay.
