Medicare is a form of health care insurance designed by the federal government for senior citizens, in addition to individuals with certain disabilities and sicknesses. When someone that has Medicare needs rehab for instances of drug or alcohol abuse, their rehabilitation will be either covered fully by their Medicare health insurance or to a significant degree. The only real catch is, the person must acquire treatment from your alcohol and drugs rehab facility which accepts Medicare. Before the individual will be allowed to start treatment, they can also get to visit their medical doctor who must state that treatment services are medically necessary, and the doctor will usually approve what type of rehab the person will take part in. Medicare Part An and Part B cover several types of rehab services. Medicare Part A covers an inpatient stay in a Medicare accepted program if the individual has to be hospitalized because of their problem, as well as the costs that they will have to cover personally are the same as every other hospital stay. Medicare Part B will partially cover outpatient treatment in the Medicare accepted facility, and the individual will have to cover whatever Part B doesn't cover with supplemental insurance or they will have to self pay.
