Medicare is a type of medical health insurance designed by the government for seniors, as well as people who have specific disabilities and illnesses. When someone who has Medicare needs rehab for instances of drug or alcohol abuse, their treatment will either be covered fully by their Medicare health insurance or to a significant extent. The only exception is, the person will have to acquire treatment from an alcohol and drugs detox facility which accepts Medicare. Before the person will be permitted to commence rehab, they will also have to visit their primary care physician who must state that rehabilitation services are medically essential, and the physician will usually approve which kind of treatment the individual will do. Medicare Part An and Part B cover various kinds of treatment services. Part A covers an inpatient stay in a Medicare accepted center when the individual should be in a hospital for his or her problem, as well as the costs which they willwill have to cover personally are the same as every other hospital stay. Medicare Part B will partly cover outpatient rehabilitation in a Medicare accepted center, and the individual will need to cover whatever Part B doesn't cover with supplement insurance or they'll have to self pay.
