Medicare is a type of health care insurance developed by the government for seniors, as well as people with certain disabilities and illnesses. When someone who has Medicare needs rehab for instances of drug or alcohol abuse, their rehab will be either covered completely by their Medicare health insurance or to a great extent. The only catch is, the person will need to acquire treatment coming from a drugs and alcohol detox facility which accepts Medicare. Before the person will be allowed to commence rehabilitation, they may also have to see their primary care physician who must state that treatment services are medically necessary, and the physician will typically approve what sort of treatment the person will do. Medicare Part An and Part B cover various kinds of rehabilitation services. Part A covers an inpatient stay in a Medicare accepted program in the event that the individual should be in a hospital for his or her problem, along with the costs that they will have to cover personally are the same as every other hospital stay. Part B will partially cover outpatient rehab in the Medicare accepted program, and the individual will need to cover whatever Part B doesn't pay for with supplemental insurance coverage or they'll have to self pay.
