Medicare is a type of medical insurance created by the government for seniors, in addition to individuals with certain disabilities and sicknesses. If a person who has Medicare needs rehabilitation for cases of drug or alcohol abuse, their rehab will either be covered completely by their Medicare health insurance or to a significant degree. The one catch is, the person must obtain treatment from the drug rehab facility which accepts Medicare. Before the individual will be allowed to begin rehab, they can also get to see their doctor who must state that rehab services are medically essential, and the doctor will typically approve what sort of rehabilitation the individual will do. Medicare Part An and Part B cover different types of rehab services. Medicare Part A covers an inpatient stay in a Medicare accepted center in the event that the individual must be in a hospital for his or her problem, along with the costs that they will have to cover personally are identical to every other stay in a hospital. Medicare Part B will partially cover outpatient rehab inside a Medicare accepted program, and the individual will need to cover whatever Medicare Part B doesn't pay for with supplement insurance coverage or they will have to self pay.
