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 benefits to receive vital treatment services for substance abuse at a wide variety of substance abuse rehab centers around the country. Medicare covers both inpatient and outpatient rehabilitation facilities, and seniors who wish to receive treatment can consult with their primary care physician to choose a rehab program covered by Medicare which would be suitable for them.
