Medicare is a kind of health care insurance designed by the U.S. government for older persons, along with individuals with certain disabilities and diseases. If someone who has Medicare needs rehab for instances of substance abuse, their treatment will be either covered fully by their Medicare health insurance or to a great extent. The only exception is, the person will have to acquire treatment from a drug rehab facility which accepts Medicare. Before the person will be allowed to start treatment, they will also have to visit their primary care physician who must declare that treatment services are medically necessary, and the doctor will generally approve what sort of rehab the person will take part in. Medicare Part An and Part B cover a variety of rehabilitation services. Part A covers an inpatient stay in a Medicare accepted center if the individual should be hospitalized for problem, and also the costs which they willwill have to pay for personally are identical to every other stay in a hospital. Part B will partly cover outpatient rehab in a Medicare accepted center, and the individual will need to cover whatever Part B doesn't cover with supplemental insurance or they're going to have to self pay.
