Medicare is a kind of medical health insurance developed by the U.S. government for older persons, in addition to people with specific disabilities and diseases. When someone who has Medicare needs treatment for instances of drug or alcohol abuse, their rehab will either be covered in full by their Medicare health insurance or to a great extent. The one catch is, the individual must receive treatment from the drug rehab facility which accepts Medicare. Before the individual will be permitted to start treatment, they may also have to visit their medical doctor who must declare that treatment services are medically necessary, and the doctor will typically approve what sort of rehab the person will take part in. Medicare Part An and Part B cover different types of rehabilitation services. Part A pays for an inpatient stay in a Medicare accepted program if the individual has to be in a hospital because of their issue, and the costs which they willwill have to pay for personally are the same as every other hospital stay. Part B will partially cover outpatient rehabilitation in a Medicare accepted program, and the individual will have to cover whatever Part B doesn't cover with supplement insurance or they will have to self pay.
