Medicare is a sort of health care insurance developed by the government for senior citizens, and also people with certain disabilities and sicknesses. When someone who has Medicare needs rehabilitation for instances of drug or alcohol abuse, their rehabilitation will be either covered completely by their Medicare health insurance or to a great degree. The only exception is, the person must obtain treatment from the drugs and alcohol detox facility which accepts Medicare. Before the individual will be allowed to begin rehabilitation, they will also have to see their medical doctor who must state that treatment services are medically needed, and the physician will typically approve which kind of rehab the individual will do. Medicare Part An and Part B cover several types of treatment services. Part A covers an inpatient stay in a Medicare accepted program when the individual should be hospitalized for their problem, and the costs that they will have to cover personally are the same as every other hospital stay. Medicare Part B will partly cover outpatient rehab within a Medicare accepted center, and the individual will need to cover whatever Medicare Part B doesn't cover with supplemental insurance or they will have to self pay.
