Medicare is a national health insurance program offered in the United States. It is currently managed by Centers for Medicare and Medicaid Services.
The program offers health insurance coverage for all American citizens aged 65 or older. Exceptions include younger people with a proven disability status as determined by the Social Security Administration. Medicare will often cover for 80% of all related medical expenses for those covered. The other 20% is usually covered by the individual's private insurance company or its Medicare health plan. This uncovered 20% is known as an "Out of Pocket Cost".
