Medicare is a type of health care insurance developed by the government for seniors, and also those that have certain disabilities and illnesses. If a person that has Medicare needs rehabilitation for instances of drug or alcohol abuse, their treatment will be either covered fully by their Medicare health insurance or to a great extent. The one catch is, the person will have to receive treatment coming from a drug rehab facility which accepts Medicare. Before the person will be allowed to commence treatment, they will also have to see their primary care physician who must state that rehabilitation services are medically necessary, and the physician will usually approve which kind of rehab the person will do. Medicare Part An and Part B cover different types of rehabilitation services. Medicare Part A covers an inpatient stay in a Medicare accepted facility in the event that the individual must be hospitalized for their problem, as well as the costs which they willwill have to cover 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 Part B doesn't cover with supplement insurance coverage or they're going to have to self pay.
