Medicare is a kind of medical insurance designed by the U.S. government for older persons, as well as those that have certain disabilities and sicknesses. If a person who has Medicare needs treatment for cases of substance abuse, their rehab will be either covered in full by their Medicare health insurance or to a significant degree. The only exception is, the person will have to receive treatment from the drug rehab facility which accepts Medicare. Before the person will be allowed to start rehabilitation, they may also have to visit their doctor who must state that treatment services are medically needed, and the physician will usually approve what sort of rehabilitation the individual will do. Medicare Part An and Part B cover different types of rehab providers. Part A covers an inpatient stay in a Medicare accepted program in the event that the individual should be in a hospital for their 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 partially cover outpatient treatment in the Medicare accepted center, and the individual will need to cover whatever Part B doesn't pay for with supplemental insurance coverage or they're going to have to self pay.
