Drug rehab facilities which deliver services to those covered by Medicare offer services in every part of the U.S., and this health insurance plan can cover both inpatient and outpatient drug rehab facilities. The only rules of thumb are that the need to receive services in a drug rehab program must be deemed medically necessary by the individual's doctor and the person's doctor must assist in setting up their treatment curriculum. Because there are health screenings which have been put into the system by Medicare in liaison with physicians who treat seniors, early diagnosis has been essential in getting seniors into an appropriate alcohol and drug treatment facility in Imperial, California that is covered through their Medicare insurance coverage. This has helped countless numbers of seniors overcome problems with addiction and in the end beat substance abuse effectively to ensure they can enjoy the rest of their life without risk relapse.
