Medicare is a type of health care insurance created by the government for seniors, and also people with certain disabilities and sicknesses. If someone who has Medicare needs rehabilitation for cases of drug or alcohol abuse, their rehabilitation will either be covered fully by their Medicare insurance or to a great extent. The one catch is, the individual will need to receive treatment from an alcohol and drugs detox facility which accepts Medicare. Before the individual will be allowed to begin treatment, they will also have to visit their primary care physician who must state that rehab services are medically necessary, and the doctor will generally approve what sort of rehabilitation the individual will do. Medicare Part An and Part B cover a variety of rehab providers. Part A covers an inpatient stay in a Medicare accepted facility when the individual has to be in a hospital for their problem, along with the costs that they will have to cover personally are identical to any other stay in a hospital. Part B will partially cover outpatient treatment in the Medicare accepted center, and the individual will have to cover whatever Part B doesn't cover with supplement insurance coverage or they've got to self pay.
