Medicare is a form of health care insurance designed by the federal government for senior citizens, and also people with certain disabilities and illnesses. If a person who has Medicare needs rehabilitation for cases of drug or alcohol abuse, their treatment will be either covered entirely by their Medicare health insurance or to a significant extent. The only exception is, the individual must acquire treatment from an alcohol and drugs detox facility which accepts Medicare. Before the individual will be permitted to start treatment, they may also have to see their primary care physician who must state that rehab services are medically necessary, and the physician will usually approve which kind of rehab the individual will take part in. Medicare Part An and Part B cover a variety of rehabilitation solutions. Medicare Part A pays for an inpatient stay in a Medicare accepted center if the individual needs to be in a hospital for their problem, as well as the costs that they will have to cover personally are identical to every other hospital stay. Medicare Part B will partially cover outpatient treatment inside a Medicare accepted center, and the individual will need to cover whatever Part B doesn't cover with supplemental insurance or they will have to self pay.
