Medicare is a kind of medical health insurance designed by the U.S. government for older persons, along with those that have certain disabilities and illnesses. If someone that has Medicare needs treatment for instances of drug or alcohol abuse, their rehab will be either covered entirely by their Medicare insurance or to a great extent. The only real catch is, the individual will need to receive treatment from the alcohol and drugs detox facility which accepts Medicare. Before the individual will be permitted to begin rehab, they may also have to see their medical doctor who must declare that rehab services are medically necessary, and the doctor will typically approve what type of treatment the person will do. Medicare Part An and Part B cover various kinds of rehabilitation providers. Medicare Part A covers an inpatient stay in a Medicare accepted program when the individual should be hospitalized for his or her issue, along with the costs that they will have to pay for personally are identical to any other stay in a hospital. Medicare Part B will partially cover outpatient rehabilitation inside a Medicare accepted program, and the individual will need to cover whatever Part B doesn't pay for with supplement insurance coverage or they're going to have to self pay.
