Medicare is a kind of medical health insurance designed by the government for older persons, and also people who have certain disabilities and illnesses. When someone who has Medicare needs rehab for instances of drug or alcohol abuse, their treatment will either be covered completely by their Medicare health insurance or to a significant degree. The only catch is, the person will have to acquire treatment from your drug rehab facility which accepts Medicare. Before the person will be permitted to start rehab, they will also have to see their medical doctor who must declare that rehabilitation services are medically necessary, and the doctor will generally approve what sort of rehab the person will do. Medicare Part An and Part B cover different types of rehabilitation services. Part A pays for an inpatient stay in a Medicare accepted program if the individual needs to be hospitalized for their problem, and the costs that they will have to pay for personally are the same as every other hospital stay. Part B will partly cover outpatient rehabilitation in a Medicare accepted facility, and the individual will need to cover whatever Medicare Part B doesn't pay for with supplemental insurance coverage or they're going to have to self pay.
