Medicare is a form of health care insurance developed by the government for senior citizens, as well as people who have certain disabilities and illnesses. If someone who has Medicare needs rehab for cases of drug or alcohol abuse, their treatment will be either covered in full by their Medicare insurance or to a great extent. The only real catch is, the individual must receive treatment from your drug rehab facility which accepts Medicare. Before the person will be permitted to commence rehab, they can also get to see their physician who must declare that rehabilitation services are medically necessary, and the physician will generally approve what type of rehab the individual will take part in. Medicare Part An and Part B cover different types of rehabilitation services. Part A covers an inpatient stay in a Medicare accepted center when the individual needs to be hospitalized because of their problem, as well as the costs which they willwill have to cover personally are the same as any other stay in a hospital. Part B will partially cover outpatient rehabilitation inside a Medicare accepted program, and the individual will need to cover whatever Medicare Part B doesn't pay for with supplemental insurance or they're going to have to self pay.
