Drug addiction and alcoholism affects 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 wide variety of substance abuse rehabilitation programs around the country. Medicare covers both inpatient and outpatient treatment 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 be suitable for them.
