Medicare is a kind of medical health insurance created by the federal government for senior citizens, along with people who have certain disabilities and illnesses. When someone who has Medicare needs rehab for instances of substance abuse, their rehabilitation will be either covered entirely by their Medicare health insurance or to a great extent. The only real catch is, the individual will have to receive treatment coming from a drugs and alcohol detox facility which accepts Medicare. Before the person will be allowed to begin rehabilitation, they may also have to visit their doctor who must state that rehab services are medically necessary, and the doctor will generally approve which kind of rehabilitation the person will do. Medicare Part An and Part B cover different types of rehab providers. Part A pays for an inpatient stay in a Medicare accepted program in the event that the individual has to be in a hospital for issue, as well as the costs that they will have to pay for personally are the same as any other stay in a hospital. Part B will partially cover outpatient rehabilitation in the Medicare accepted center, and the individual will have to cover whatever Medicare Part B doesn't cover with supplement insurance or they'll have to self pay.
