Drug addiction and alcoholism affects many older Americans and seniors, and this problem 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 drug or alcohol addiction at a wide variety of drug rehab facilities around the country. Medicare covers both inpatient and outpatient rehab programs, and seniors who wish to receive treatment can consult with their primary care physician to choose a treatment program covered by Medicare which would be suitable for them.
