Medicare is a form of health care insurance developed by the government for older folks, along with those that have certain disabilities and diseases. If an individual that has Medicare needs rehab for cases of drug or alcohol abuse, their rehab will be either covered in full by their Medicare insurance or to a great extent. The only real catch is, the individual must acquire treatment from the drugs and alcohol detox facility which accepts Medicare. Before the person will be allowed to start rehab, they will also have to visit their primary care physician who must declare that treatment services are medically needed, and the doctor will generally approve which kind of rehab the person will do. Medicare Part An and Part B cover various kinds of treatment services. Medicare Part A pays for an inpatient stay in a Medicare accepted facility when the individual has to be in a hospital for his or her issue, and the costs that they will have to cover personally are identical to every other hospital stay. Medicare Part B will partially cover outpatient rehab in the Medicare accepted program, and the individual will have to cover whatever Part B doesn't pay for with supplement insurance or they will have to self pay.
