Medicare is a form of health care insurance designed by the government for older persons, in addition to people with certain disabilities and sicknesses. If someone who has Medicare needs treatment for cases of drug or alcohol abuse, their rehab will either be covered entirely by their Medicare health insurance or to a significant degree. The only exception is, the person will need to obtain treatment from the drug rehab facility which accepts Medicare. Before the person will be allowed to commence rehab, they may also have to visit their primary care physician who must state that rehabilitation services are medically needed, and the physician will generally approve which kind of rehabilitation the individual will do. Medicare Part An and Part B cover various kinds of treatment providers. Part A covers an inpatient stay in a Medicare accepted center in the event that the individual needs to be in a hospital for their problem, and the costs which they willwill have to pay for personally are the same as any other stay in a hospital. Medicare Part B will partly cover outpatient treatment in a Medicare accepted facility, and the individual will have to cover whatever Medicare Part B doesn't cover with supplemental insurance coverage or they will have to self pay.
