Medicare is a form of health insurance created by the government for older persons, in addition to people who have certain disabilities and sicknesses. If an individual who has Medicare needs rehab for instances of drug or alcohol abuse, their rehab will either be covered in full by their Medicare health insurance or to a significant degree. The only real exception is, the person will need to receive treatment from your drug rehab facility which accepts Medicare. Before the individual will be allowed to commence rehab, they will also have to visit their medical doctor who must declare that rehabilitation services are medically necessary, and the physician will usually approve which kind of rehabilitation the individual will do. Medicare Part An and Part B cover various kinds of rehab services. Medicare Part A pays for an inpatient stay in a Medicare accepted center when the individual needs to be hospitalized because of their problem, as well as the costs that they will have to cover personally are the same as every other hospital stay. Medicare Part B will partly cover outpatient rehabilitation in a Medicare accepted program, 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.
