Drug addiction and alcoholism can effect many older Americans and seniors, and this issue continues to grow as each year passes. 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 Medicare benefits to receive vital treatment services for substance abuse at a variety of drug and alcohol rehabilitation centers around the country. Medicare covers both inpatient and outpatient rehab programs, and seniors who are in need of help can consult with their primary care physician to choose a treatment program covered by Medicare which would be suitable for them.
