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 program funded through the federal government for Americans in this age bracket, can use their benefits to receive vital treatment services for drug or alcohol addiction at a wide variety of drug and alcohol treatment facilities around the country. Medicare covers both inpatient and outpatient rehab programs, and seniors who wish to receive treatment can consult with their primary care physician to choose a rehab program covered by Medicare which would fit his or her particular needs.
