Medicare is a type of medical insurance developed by the government for senior citizens, and also people who have certain disabilities and illnesses. If someone who has Medicare needs treatment for instances of drug or alcohol abuse, their treatment will either be covered in full by their Medicare insurance or to a significant degree. The only catch is, the individual will need to receive treatment from the drug rehab facility which accepts Medicare. Before the person will be permitted to start rehabilitation, they will also have to see their physician who must declare that rehabilitation services are medically necessary, and the physician will usually approve what type of treatment the individual will take part in. Medicare Part An and Part B cover a variety of treatment providers. Part A covers an inpatient stay in a Medicare accepted facility when the individual needs to be in a hospital for his or her issue, along with the costs that they will have to cover personally are identical to every other hospital stay. Part B will partly cover outpatient treatment inside a Medicare accepted program, 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.
