Medicare is a form of medical health insurance created by the government for seniors, along with people who have certain disabilities and diseases. When someone that has Medicare needs treatment for cases of drug or alcohol abuse, their rehab will be either covered entirely by their Medicare insurance or to a significant extent. The only exception is, the person must acquire treatment from a drugs and alcohol detox facility which accepts Medicare. Before the individual will be allowed to start rehabilitation, they may also have to visit their medical doctor who must declare that treatment services are medically necessary, and the physician will typically approve what type of rehab the person will take part in. Medicare Part An and Part B cover various kinds of rehab services. Part A pays for an inpatient stay in a Medicare accepted center if the individual has to be hospitalized for his or her issue, along with the costs which they willwill have to pay for personally are the same as every other hospital stay. Part B will partly cover outpatient rehab in a Medicare accepted program, and the individual will need to cover whatever Medicare Part B doesn't cover with supplemental insurance or they're going to have to self pay.
