Medicare is a form of medical insurance developed by the federal government for seniors, and also people with specific disabilities and illnesses. If an individual who has Medicare needs treatment for cases of drug or alcohol abuse, their rehabilitation will be either covered completely by their Medicare health insurance or to a great extent. The only catch is, the person will have to obtain treatment from your drug rehab facility which accepts Medicare. Before the individual will be allowed to commence rehabilitation, they may also have to visit their primary care physician who must declare that rehabilitation services are medically essential, and the physician will typically approve what type of rehabilitation the individual will do. Medicare Part An and Part B cover different types of treatment providers. Medicare Part A covers an inpatient stay in a Medicare accepted facility when the individual needs to be in a hospital for their problem, along with the costs which they willwill have to cover personally are the same as any other hospital stay. Medicare Part B will partly cover outpatient treatment in a Medicare accepted center, and the individual will need to cover whatever Medicare Part B doesn't cover with supplement insurance or they will have to self pay.
