Medicare is a type of health insurance developed by the U.S. government for older persons, as well as people with certain disabilities and illnesses. If a person who has Medicare needs treatment for cases of substance abuse, their rehabilitation will be either covered fully by their Medicare insurance or to a great extent. The only real catch is, the person will have to acquire treatment from a drugs and alcohol detox facility which accepts Medicare. Before the person will be permitted to begin rehab, they may also have to see their primary care physician who must declare that treatment services are medically necessary, and the physician will generally approve which kind of treatment the person will take part in. Medicare Part An and Part B cover different types of treatment services. Part A pays for an inpatient stay in a Medicare accepted facility if the individual has to be hospitalized because of their issue, along with the costs which they willwill have to pay for personally are the same as every other stay in a hospital. 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 supplemental insurance coverage or they're going to have to self pay.
