Drug addiction and alcoholism can effect many older Americans and seniors, and this issue is projected to only worsen in the coming years. Seniors who are covered through the Medicare program, an insurance plan funded through the federal government for Americans in this age bracket, can use their benefits to receive treatment services for addiction at a variety of drug rehab programs around the country. Medicare covers both inpatient and outpatient treatment programs, and seniors who are in need of help can consult with their primary care physician to choose a treatment program covered by Medicare which would fit his or her particular needs.
