Medicare is a type of health insurance designed by the government for older persons, as well as individuals with certain disabilities and sicknesses. If a person who has Medicare needs treatment for cases of substance abuse, their rehab will be either covered entirely by their Medicare health insurance or to a great extent. The only real catch is, the individual will have to acquire treatment from a drug rehab facility which accepts Medicare. Before the individual will be allowed to start treatment, they can also get to see their primary care physician who must state that rehabilitation services are medically necessary, and the doctor will typically approve what type of treatment the person will do. Medicare Part An and Part B cover various kinds of treatment providers. Medicare Part A pays for an inpatient stay in a Medicare accepted program when the individual has to be hospitalized because of their issue, along with the costs which they willwill have to pay for personally are the same as every other stay in a hospital. Medicare Part B will partly cover outpatient rehab in the Medicare accepted center, and the individual will need to cover whatever Part B doesn't pay for with supplement insurance coverage or they're going to have to self pay.
