Medicare is a form of medical health insurance created by the government for older persons, along with people with certain disabilities and sicknesses. If someone that has Medicare needs rehabilitation for cases of drug or alcohol abuse, their treatment will either be covered entirely by their Medicare health insurance or to a great extent. The only real catch is, the individual will need to receive treatment coming from a drug rehab facility which accepts Medicare. Before the person will be permitted to start rehabilitation, they will also have to visit their physician who must declare that rehab services are medically needed, and the doctor will usually approve what type of treatment the individual will do. Medicare Part An and Part B cover several types of rehab services. Medicare Part A pays for an inpatient stay in a Medicare accepted program if the individual should be in a hospital for his or her problem, and also the costs which they willwill have to cover personally are the same as every other hospital stay. Medicare Part B will partially cover outpatient treatment in the Medicare accepted program, and the individual will have to cover whatever Medicare Part B doesn't cover with supplemental insurance or they're going to have to self pay.
