Alcohol and drug rehabilitation centers which accept Medicare are available in almost all parts of the U.S., and this health insurance plan can cover both inpatient and outpatient drug and alcohol treatment programs. The only stipulations are that the need to receive services in a drug rehab facility must be deemed medically necessary by the person's physician and the individual's doctor is required to lay out their drug rehab curriculum. Due to the fact that there are health screenings that have been put into effect by Medicare in liaison with physicians who treat older Americans, early detection has been essential in getting seniors to a suitable alcohol and drug treatment facility in Three Rivers, California that is offered through their Medicare plan. This has helped many older Americans resolve problems with addiction and eventually overcome substance abuse effectively to ensure they can enjoy the rest of their lives without the threat of relapse.
