Medicare is a type of medical health insurance designed by the U.S. government for senior citizens, as well as individuals with specific disabilities and diseases. If an individual who has Medicare needs rehabilitation for cases of drug or alcohol abuse, their treatment will either be covered fully by their Medicare health insurance or to a significant extent. The only exception is, the individual will need to receive treatment from your alcohol and drugs rehab facility which accepts Medicare. Before the individual will be permitted to begin treatment, they may also have to visit their primary care physician who must state that rehab services are medically essential, and the physician will usually approve which kind of treatment the individual will take part in. Medicare Part An and Part B cover various kinds of rehab services. Medicare Part A pays for an inpatient stay in a Medicare accepted program if the individual should be hospitalized for their problem, as well as the costs that they will have to pay for personally are the same as any other stay in a hospital. Part B will partly cover outpatient rehabilitation in the Medicare accepted center, and the individual will need to cover whatever Medicare Part B doesn't pay for with supplemental insurance or they're going to have to self pay.
