Medicare is a type of health insurance created by the U.S. government for senior citizens, and also people with specific disabilities and illnesses. When someone who has Medicare needs treatment for instances of drug or alcohol abuse, their treatment will be either covered completely by their Medicare health insurance or to a significant extent. The only exception is, the individual must receive treatment from the alcohol and drugs detox facility which accepts Medicare. Before the individual will be allowed to begin treatment, they will also have to see their physician who must declare that rehabilitation services are medically necessary, and the physician will usually approve what type of rehabilitation the individual will do. Medicare Part An and Part B cover various kinds of treatment providers. Part A covers an inpatient stay in a Medicare accepted facility in the event that the individual must be in a hospital for their problem, and also 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 rehab inside a Medicare accepted program, and the individual will need to cover whatever Medicare Part B doesn't cover with supplemental insurance or they will have to self pay.
