Medicare is a form of medical insurance created by the government for senior citizens, in addition to people who have specific disabilities and diseases. If someone who has Medicare needs rehab for instances of substance abuse, their rehab will be either covered fully by their Medicare health insurance or to a great extent. The one exception is, the individual must obtain treatment from the drugs and alcohol detox facility which accepts Medicare. Before the person will be permitted to begin rehabilitation, they may also have to visit their primary care physician who must declare that rehabilitation services are medically necessary, and the physician will typically approve which kind of rehabilitation the individual will do. Medicare Part An and Part B cover different types of rehabilitation providers. Medicare Part A pays for an inpatient stay in a Medicare accepted program if the individual must be hospitalized because of their problem, as well as the costs which they willwill have to cover personally are identical to every other hospital stay. Part B will partially cover outpatient rehabilitation in the Medicare accepted facility, and the individual will need to cover whatever Medicare Part B doesn't cover with supplemental insurance coverage or they'll have to self pay.
