Medicare is a form of health care insurance created by the government for older persons, as well as those that have specific disabilities and diseases. When someone who has Medicare needs rehab for instances of substance abuse, their rehabilitation will be either covered fully by their Medicare health insurance or to a great extent. The one exception is, the individual will need to receive treatment from the drugs and alcohol detox facility which accepts Medicare. Before the individual will be permitted to start rehab, they will also have to see their primary care physician who must state that rehabilitation services are medically needed, and the physician will typically approve what type of rehab the person will do. Medicare Part An and Part B cover different types of rehab solutions. Part A covers an inpatient stay in a Medicare accepted center when the individual should be in a hospital for his or her problem, and also the costs that they will have to pay for personally are the same as any other stay in a hospital. Medicare Part B will partially cover outpatient treatment in the Medicare accepted facility, 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.
