Medicare is a form of health insurance developed by the U.S. government for older persons, as well as people with certain disabilities and sicknesses. When someone who has Medicare needs rehab for cases of drug or alcohol abuse, their treatment will either be covered entirely by their Medicare insurance or to a significant extent. The only real catch is, the individual must obtain treatment from the drug rehab facility which accepts Medicare. Before the individual will be allowed to commence treatment, they will also have to see their medical doctor who must declare that rehab services are medically needed, and the physician will typically approve what type of rehabilitation the person will do. Medicare Part An and Part B cover a variety of rehab services. Part A pays for an inpatient stay in a Medicare accepted program when the individual needs to be in a hospital because of their problem, and the costs which they willwill have to pay for personally are identical to any other hospital stay. Medicare Part B will partially cover outpatient treatment inside a Medicare accepted program, and the individual will need to cover whatever Part B doesn't cover with supplement insurance or they've got to self pay.
