Medicare is a form of health care insurance developed by the government for seniors, as well as those that have certain disabilities and sicknesses. When someone who has Medicare needs rehab for instances of substance abuse, their rehabilitation will be either covered entirely by their Medicare insurance or to a significant degree. The one catch is, the individual will need to receive treatment from your drugs and alcohol detox facility which accepts Medicare. Before the individual will be permitted to commence treatment, they will also have to visit their primary care physician who must state that rehabilitation services are medically necessary, and the physician will generally approve what type of rehabilitation the individual will take part in. Medicare Part An and Part B cover a variety of rehabilitation services. Part A covers an inpatient stay in a Medicare accepted facility if the individual needs to be in a hospital for his or her problem, along with the costs that they will have to pay for personally are the same as any other stay in a hospital. Part B will partly cover outpatient rehabilitation in a Medicare accepted program, and the individual will have to cover whatever Part B doesn't cover with supplemental insurance coverage or they're going to have to self pay.
