Drug and alcohol addiction plagues many elderly Americans and senior citizens, and this situation is going to only become worse in the years to come. senior citizens that are insured by the Medicare program, an insurance plan provided via the federal government for people in this age group, may use their health coverage to receive essential rehab services for substance abuse at a number of alcohol and drug rehabilitation centers around the South San Francisco, California area. Medicare covers both residential and outpatient drug and alcohol treatment centers, and seniors in South San Francisco whom decide to get treatment should contact their primary care doctor to decide on a South San Francisco, California drug rehab facility who accepts Medicare which will be workable for them.
