Medicare is a type of health insurance developed by the government for senior citizens, and also those that have specific disabilities and diseases. If someone who has Medicare needs rehabilitation for cases of substance abuse, their rehabilitation will either be covered in full by their Medicare insurance or to a significant extent. The only exception is, the individual will need to obtain treatment from the drugs and alcohol detox facility which accepts Medicare. Before the individual will be allowed to start treatment, they may also have to visit their doctor who must declare that rehab services are medically necessary, and the doctor will typically approve which kind of rehab the individual will do. Medicare Part An and Part B cover several types of rehabilitation services. Medicare Part A covers an inpatient stay in a Medicare accepted program when the individual should be hospitalized for his or her problem, and also the costs that they will have to pay for personally are the same as any other stay in a hospital. Part B will partly cover outpatient rehabilitation within a Medicare accepted center, and the individual will have to cover whatever Medicare Part B doesn't cover with supplement insurance or they've got to self pay.
