Medicare is a type of medical health insurance developed by the federal government for older persons, along with people with specific disabilities and diseases. When someone that has Medicare needs rehabilitation for cases of drug or alcohol abuse, their rehabilitation will either be covered completely by their Medicare insurance or to a great extent. The only exception is, the person must obtain treatment from the alcohol and drugs rehab facility which accepts Medicare. Before the person will be allowed to begin rehab, they may also have to see their medical doctor who must state that rehabilitation services are medically necessary, and the doctor will generally approve what type of rehab the person will do. Medicare Part An and Part B cover different types of rehab solutions. Medicare Part A pays for an inpatient stay in a Medicare accepted facility in the event that the individual needs to be in a hospital for his or her problem, along with the costs which they willwill have to cover personally are the same as every other stay in a hospital. Medicare Part B will partially cover outpatient rehab in a Medicare accepted program, and the individual will need to cover whatever Medicare Part B doesn't cover with supplemental insurance or they've got to self pay.
