Medicare is a kind of health care insurance designed by the government for senior citizens, and also people who have certain disabilities and diseases. If someone that has Medicare needs rehab for cases of drug or alcohol abuse, their treatment will either be covered entirely by their Medicare health insurance or to a significant extent. The one exception is, the individual must receive treatment from the drugs and alcohol detox facility which accepts Medicare. Before the person will be permitted to begin treatment, they can also get to visit their primary care physician who must state that rehabilitation services are medically necessary, and the doctor will usually approve what type of rehab the individual will do. Medicare Part An and Part B cover a variety of treatment services. Part A covers an inpatient stay in a Medicare accepted center when the individual should be in a hospital because of their problem, as well as the costs which they willwill have to cover personally are the same as every other hospital stay. Part B will partially cover outpatient treatment within a Medicare accepted facility, and the individual will need to cover whatever Medicare Part B doesn't cover with supplement insurance or they'll have to self pay.
