Drug addiction and alcoholism can effect many older Americans and seniors, and this problem 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 Medicare benefits to receive treatment services for drug or alcohol addiction at a variety of drug treatment facilities around the country. Medicare covers both inpatient and outpatient rehabilitation facilities, and seniors who are in need of help can consult with their primary care physician to choose a rehab program covered by Medicare which would fit his or her particular needs.
