Medicare is a type of medical health insurance created by the U.S. government for older persons, along with people with certain disabilities and sicknesses. If a person who has Medicare needs rehabilitation for cases of substance abuse, their treatment will be either covered fully by their Medicare health insurance or to a significant extent. The only real exception is, the individual must obtain treatment coming from a drugs and alcohol detox facility which accepts Medicare. Before the person will be allowed to begin rehab, they may also have to see their doctor who must state that rehab services are medically essential, and the physician will generally approve which kind of rehab the person will do. Medicare Part An and Part B cover a variety of rehab services. Medicare Part A pays for an inpatient stay in a Medicare accepted program when the individual needs to be in a hospital for his or her issue, as well as the costs that they will have to pay for personally are identical to every other stay in a hospital. Medicare Part B will partially cover outpatient treatment in 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.
