Medicare is a sort of health care insurance developed by the U.S. government for older persons, along with people with certain disabilities and sicknesses. When someone that has Medicare needs rehabilitation for instances of substance abuse, their rehabilitation will be either covered completely by their Medicare insurance or to a great extent. The only catch is, the individual will have to obtain treatment from a drugs and alcohol detox facility which accepts Medicare. Before the person will be allowed to start rehab, they may also have to see their doctor who must declare that rehabilitation services are medically needed, and the doctor will generally approve what sort of rehabilitation the person will do. Medicare Part An and Part B cover several types of rehab providers. Medicare Part A covers an inpatient stay in a Medicare accepted facility if the individual should be in a hospital because of their problem, 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 rehab in the Medicare accepted program, and the individual will need to cover whatever Medicare Part B doesn't pay for with supplemental insurance or they'll have to self pay.
