Medicare is a form of medical insurance developed by the federal government for senior citizens, as well as those that have certain disabilities and diseases. If someone who has Medicare needs rehab for instances of substance abuse, their rehabilitation will either be covered fully by their Medicare health insurance or to a significant extent. The one exception is, the individual will have to acquire treatment from your drug rehab facility which accepts Medicare. Before the person will be allowed to begin treatment, they can also get to see their primary care physician who must state that rehabilitation services are medically necessary, and the physician will usually approve which kind of treatment the person will take part in. Medicare Part An and Part B cover various kinds of rehabilitation providers. Medicare Part A covers an inpatient stay in a Medicare accepted program if the individual must be hospitalized for their issue, and the costs which they willwill have to cover personally are identical to any other stay in a hospital. Medicare Part B will partially cover outpatient rehab in the Medicare accepted facility, and the individual will need to cover whatever Medicare Part B doesn't pay for with supplemental insurance coverage or they'll have to self pay.
