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 Medicare benefits to receive vital treatment services for drug or alcohol addiction at a wide variety of drug and alcohol treatment centers around the country. Medicare covers both inpatient and outpatient rehabilitation programs, and seniors who wish to receive help can consult with their primary care physician to choose a rehab program covered by Medicare which would fit his or her particular needs.
