Medicare is a kind of medical insurance developed by the government for senior citizens, in addition to those that have certain disabilities and diseases. If someone that has Medicare needs treatment for cases of drug or alcohol abuse, their rehabilitation will either be covered entirely by their Medicare insurance or to a great extent. The only real exception is, the person must obtain treatment from an alcohol and drugs detox facility which accepts Medicare. Before the person will be allowed to commence rehabilitation, they will also have to visit their primary care physician who must state that treatment services are medically necessary, and the physician will generally approve what type of treatment the person will do. Medicare Part An and Part B cover a variety of treatment providers. Medicare Part A pays for an inpatient stay in a Medicare accepted center when the individual must be hospitalized because of their problem, and the costs which they willwill have to pay for personally are the same as any other hospital stay. Part B will partly cover outpatient rehab within a Medicare accepted program, and the individual will need to cover whatever Medicare Part B doesn't cover with supplemental insurance coverage or they've got to self pay.
