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 by Medicare, an insurance plan funded through the federal government for Americans in this age bracket, can use their Medicare benefits to receive treatment services for substance abuse at a wide variety of drug rehabilitation programs 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 be suitable for them.
