Drug and alcohol addiction impacts many mature Americans and senior citizens, and this problem is going to only worsen in the near and distant future. Seniors that are insured through the Medicare program, a health coverage program available through the federal government for Americans in this age range, may utilize their health insurance to take part in essential rehab treatment for substance abuse at a variety of drug treatment programs throughout the Gridley, California area. Medicare covers both residential and outpatient drug treatment programs, and senior Americans in Gridley who decide to take part in rehabilitation should contact their primary care doctor to choose a Gridley, California alcohol and drug treatment center that will accept Medicare which would be workable for them.
